We are about to have a vertical system installed by Dandelion in fact the drill rig will be here on Friday Aug 13th (yeah the old superstition). We are located close to Kingston NY and after a small heating oil leak decided to get out of the fossil fuel business! We checked out mini splits but found the maintenance on 6 interior units to be excessive not to mention the holes in the house walls for the refrigerant and drain lines. Dandelion designed a 5 ton system which requires two holes for the vertical loops. The house is 1920 sq ft and has an open design. We also had to replace the old hot air duct system as it was small and made from ductboard. After seeing the condition of the ductboard it was money well spent! Will update this comment after the drilling and install.
@@NetZeroTech Today they finished drilling two holes 288ft. Very noisy for three days! Waiting for next phase which will be the trenching and going thru the foundation. Can't wait to remove the oil tank and oil along with the furnace.
@@chrismaxny4066 Great! Thank you very much for sharing. It sounds like the noisiest part is over. Good luck for the rest of the project. I'm sure it'll feel great to remove the oil tank and furnace. Exciting! I wish you lots of joy with the new system, the savings, the comfort, and the clean air, once it's installed. I'd appreciate hearing more. I think it would be interesting for others to learn about the next steps, the progress, and result of the project.
@@chrismaxny4066 Hi ChrisMax, How are you? Is your system installed? What has the experience been so far? I thought your previous comments where really interesting for others to learn from. Thanks again!
@@NetZeroTech We've been living with geothermal for three days and the cooling is phenomenal! Dandelion installed a 5 ton Aaon geothermal heat pump but we didn't get the desuperheater as our electric water heater is extremely efficient. However if your household has more than two people the desuperheater will be helpful in providing additional hot water. If you are in the northeast of the US Dandelion is without a doubt the best company to hire to install a geothermal system. All the people from initial contact to the final install and adjustments were respectful and helpful. Their quality of work and attention to detail is top of the line. Our project involved upgrading our main electric panel to 200 amps and completely replacing the ductwork. We were very happy to so because an electric car is in our future and the ductwork was made of ductboard that was 30 plus years old. These two upgrades added $13,000 USD to the cost of the geothermal project but I consider them to be essential changes that would have been done at some point. The entire experience of installing geothermal beyond the cost is more like an adventure. The process started with a phone call to Dandelion at the end of April 2021. We had the site survey in June which consisted of taking photos of the entire interior of the house with a 3d imaging camera so Dandelion could design the proper system for our home. Also the site for the drilling and trenching on our property was chosen. Dandelion actually wanted to start drilling in July but I put them off until mid-August which is when the drilling rig arrived. This was the part of the project that kept me awake at night. Both the neighbor's and my wells were very close (50ft) to the drill holes and as a precaution I had tested our wells before the drilling started. The drilling was extremely noisy, heard all over the neighborhood, and took two and a half days. This is the worst and most messy part of the entire project but also very interesting. Trenching to the foundation wall came next which was quiet compared to the drilling and not as bad as I expected. After reading what I consider a hit piece on Dandelion in Forbes magazine which mentioned cracked foundation walls caused by holes needed for the geothermal loops I was apprehensive! Turned out the foundation was just fine after drilling the holes but have the shopvac ready as there will be a lot of concrete dust blowing into the basement as the drill comes thru the wall. The rest of the install was a piece of cake and again Dandelion did an outstanding running the electric, connecting the loops to the geo heat pump, and finishing up cleaning the work site. The outside landscape was left in rough ready to be top soiled and seeded condition as per the contract. The cost of just Dandelion's part of the project (all in USD) starting with the total: $40,375 - $1750 (discount for paying up front) - $9820 (incentive) Price before tax credit: $28,805 (what we paid) -$7489 (tax credit) Final Total: $21,316

How the excel sheet has calculated the breakeven point, Break even point is when the energy cost savings equal the amount of the upfront cost but here it is calvulated using the energy cost equals the upfront cost? I might be wrong with my concept, Can you have the explaination for it? Thank You for wonderful video!
Hi @DHRUMILKHATRI-br8mj, Thank you for your feedback and looking into the calculations. I appreciate it. So, for the electric heating with electricity from a solar panel system, the breakeven is calculated assuming that after the installation of the system (solar panel system or geothermal system), there is negligible electricity cost. This is true in case you have energy storage, e.g. in form of net metering or a battery bank. So, without inflation and time value of money, the system is paid down after the upfront cost matches the electricity cost equivalent that you would have paid for with electric heating and no solar panel system. I'll try to update and document the assumptions on the breakeven calculations in the coming weeks. What does your current heating and cooling system look like? Do you have a system in mind that you'd like to switch to? Warm regards, Katha

Your example location, Colorado, spends most of its energy budget on heating and not so much on cooling. But what of a desert area, such as Arizona, New Mexico,, Nevada, Texas, and high sierra areas of California? Yes, the desert gets cold at night, so heating is required, but cooling is often more than half the budget. How do the numbers work out there?

Geothermal can work great for cooling! In fact, you can DIY low-tech geothermal, if you can manage the excavations..that is the hardest part. Running fluid loops in the ground, harvests the earth’s mean-temp…that is approx. 55F., at about 6’ deep, most areas where people live. The key to the thrift of running geothermal, is that equipment to heat or cool, only has to heat or cool maybe about 30 degrees different from the earth’s temp, but with an above-ground system, the devices must heat or cool a far bigger difference…if I want the house temp at 70F., and outside air is 32F., the machines must warm the house by close to 40 degrees. But a geothermal “preconditioning”, allows the machinery to only work to make about 20F….half the work. Same for chilling….an AC unit must compensate the difference between say, a 100F. day, so must chill down 30F to reach the target temp. Or, a central HVAC must warm up a house from whatever the cold outside is…That costs energy. Hundreds, sometimes a couple thousand watts while on. States with more heating hours, or with more cooling hours, adjust their pricing units to cause higher costs for whichever one needs, to cost the most…those in heating climates, pay big energy bills to heat, but less to cool…and vice versa. Ya just can’t get ahead, with how systems have been rigged. But really, if you want your house at 70F., geothermal-fed machines could feasibly only require the geothermal fluid temp with a fan blowing across the tubes in fins, only using enough energy to power the pump circulating the fluid, & the fan. What if you had such a system (a low-tech geothermal) running 24/7, basically keeping the house at an average temp of the ground, & only adding the bit of auxiliary heat or cooling as needed? Combines regular heat & cool system, but adding a low tech geothermal, that only circulates fluid between ground to cooling fins with a fan blowing on it…maybe controlled by a thermostat, so it isn’t blowing ground-temp all the time, but enough to augment the regular system…THAT could be more easily retrofitted, though, there’s a little learning curve to it, it’s still very simple.
Hi Winter Star, That's right. Making use of the ground temperature helps to reduce the temperature difference between the house and its surrounding. The "low-tech" geothermal sounds like an interesting idea. Thank you for sharing!
I just had my pool (5.5m wide x 13m long x 1-3 m deep) removed and filled in. I very much wanted to lay down some loops, probably could have had 2 levels in the deep end. But even though the excavation was "free", I don't think I could have gotten more than a ton of capacity in that area, or in any event as much as I would need for my ~330m2 house. Also, I think the inspector and contractor would have made things difficult. Finally, even if that all shook out OK, maybe I would never use it for whatever reason. My other thought was just run some simple loop to cool a decent volume of air that I could bathe my AC condenser in when it's on. Would just be a small fan. But again, inspector and contractor would not want the hassle of understanding where I was coming from. In the end, I think it was some lost opportunity, but would have been not worth it or even be possible.
Most US homes typically use 12 kW (3.4 tons). Most installers expect a 3 or 5 ton system to be most suitable in a residential home. Make sure to insulate well to avoid efficiency losses that can also arise from oversizing the system. In most cases, improving the insulation and then choosing a smaller system helps to reduce both upfront and recurring expenses.
Hi, Thank you for watching and leaving a comment. Not specifically for Connecticut. However, this video on cold-climate heat pumps might be interesting for you: th-cam.com/video/3ExhnTuYNZ4/w-d-xo.html Thank you, Katha
Anyone know where I can get my geothermal system designed. I would like to do most of the plumbing myself and have professional HVAC person install the heat pumps. Thanks
Hi Steve, Great to hear you're going to install a geothermal system. Where you can get your geothermal system designed depends on your location. Heating and cooling is a fairly local business, since the system designer, who typically also wants to be the installer, would want to come by and take a look at the property. Some companies have locations in various states. Does anyone else have different thoughts? Thanks, Katha
@@NetZeroTech International Ground Source Heat Pump Association in the US offers a range of information and directory of services. Including list of certified installers.
Can you elaborate on the logic behind this "Additional Heating Required" assumption? Shouldn't this apply to both the electric heating and geothermal? The way I'm looking at it, if there are 65 days in a year where the clouds prevent enough solar to be generated for geothermal then the same should apply for electric heating from solar?
Hi Eaton, Thanks for commenting! 🙏 I'm sure many people have the same question. Many heat pumps in cold climates have a backup heat source known as auxiliary heat. Cold-climate heat pump technology has massively improved in the past years. So, many cold-climate heat pump models have become very efficient even at low temperatures that auxiliary heat is not required anymore. When the outside temperature is below 30 degrees, heat pumps with auxiliary heat auto-engage emergency heat to keep up with demand from the interior thermostat. Your heating system will then use the secondary system, e.g. an electric heat strip, with your normal heating. Electric heating systems do not have auxiliary heat, because they don't work more efficiently at lower flow temperatures (higher ambient temperatures). They essentially are in the less efficient and more expensive auxiliary heat mode at all times. I hope this helps and you are well. 😊 Happy holidays! 🎊 Katha PS - Feel free to checkout these videos to learn more about Heat Pumps and additional heating: Do AIR SOURCE HEAT PUMPS work in cold climates?

Same boat here... It is such a toss up! A coworker moved from oil to normal heat pump, but it just isn't as 'warm' feeling... Which is a common complaint because heating the air is just not as warm feeling as the IR heating surfaces from the radiators. If the air is cool, but everything you touch is cold, you are going to feel cooler. Another problem is that he is heavy on the emergency heat. So he is saving money... But not nearly as much as expected. He is looking at windows, insulation, etc to help with that. But again, a radiator heats surfaces more, so an oldish drafty house can still feel cozy. But switching to forced air makes drafts much more aparant. If you are already on forced air, moving to geo thermal isn't going to feel much different. And most people on a forced air system are already going to have made improvements on drafts, and outright air leak problems before looking at any kind of heat pump system. The other advantage of geo thermal is there is less need for emergency heat. Where we are at we are often right near the Frost transition. So it starts out raining, transitions to snow/ice, and you can get humidity build up. This ironically causes your heat pump to overheat as the airflow is cut off from the outdoor unit, and you then rely more on the emergency heat. So a defrost cycle is run, which means turning on the AC in winter to defrost the outdoor coils. Obviously some install choices can help with this, but it is a weirdly common problem, and can cause issues. With geo thermal this just isn't an issue. There are no outdoor coils to freeze in the rain that need airflow. The coils are 6-8' under ground where it stays a nice cool 50ish degrees year round. So any heating you do is pulling 50*f ground up to 70 inside for a 30* temp difference. Or down from 90 oitside to 70 inside for a 20* difference. You aren't going from outdoor -10*f up to 70*f in winter. That is where the savings is. Emergency heat may still be needed if you can pump ground heat faster than your home is loosing it, but cutting drafts, insulating, etc can help that a lot.
I have a friend that purchased a house with a geo thermal unit he has had the compressor replaced ever 7 years and replace the unit once he hasn’t saved a dime after 20 years he is finely thinking about going back to natural gas
Exactly, that's a great option if you have space outside and are willing to dig it up. Driveways can work well, too. Horizontal loops are also easier to do yourself, in case that's an option,.
Do you have any suggestions on how the information of geothermal heating can get passed onto whatever NGO or Governmental Agencies that can build shelter for the refugee population from the Ukraine war? There are millions of Ukrainian refugees in Poland, and I fear nobody is thinking about how to provide heated shelter for those people when Winter arrives. Combining heat pumps with geothermal heating could heat housing for refugees without requiring enormous heating fuel costs. I wish such information could get to Habit for Humanity, or the European Union or the Polish Government so they can begin to prepare now for will otherwise become a greater human catastrophe than it is now. I might add a considerable amount of the workforce for the construction could come from the refugee population itself. Do you have any ideas on how to make this happen?
Hi Aristoctles. Indeed. Thank you for sharing. That would be a great synergy of addressing urgent humanitarian needs and the resulting temporary media coverage with the long-term need of humankind to eliminate greenhouse gas emissions. I'd have to look at the long-term impact of such a project more closely. The geographical shift in residential heating from Ukrainian refugees might be temporary and the focus and the required project resources might possibly be allocated better at higher impact projects on global greenhouse gas emissions. I currently help accelerate green hydrogen for heavy industries, which takes the bulk of my time. If anyone reading this wants to take a shot at sustainable refugee shelters, happy to connect you with folks in my network. 🙏
@@NetZeroTech In fact, I have checked with a friend of mine who as a German Academic knows who to contact in the German Political Parties and Government Bureaucracy, and I will be sending a letter to them soon. I have used links to some of your videos about Geothermal to provide background explanation. I understand your interest in hydrogen long term, but Europe needs a very short term solution to the reduction of cheap Russian gas. Therefore, Germany has domestic market as well as a foreign market reasons for Geothermal Cooling
Good video, with just the one common mistake of calling “ground source heat pumps” geothermal - geothermal energy extraction is the big, industrial scale type used for power generation using steam turbines in volcanically active places like Iceland or Yellowstone. Lots of good points in the video, though, and the costs breakdown, while US specific, do give a reasonable relative indication for other parts of the world.
@@YT-jh8co Yes, the breakeven time of new constructions (also a ground-source installation instead of repairing a broken fossil fuel furnace) is typically shorter compared to retrofits.

@@chrismaxny4066 Chris, now that you have had your system for nearly a full heating season I am wondering how heating with a GSHP is different from a NG furnace. For example, they say the heat output is more consistent but not a warm (air temp). Would you say your home is just as comfortable as in the past? Also, since I am considering a mini-split, do you think a modern model with 100% efficiency at -5% and 80% efficiency at -15% would be a good choice (in CT)?
Man... It is such a question. Out here in Ohio natural gas is dirt cheap, as are electricity prices. So changing from anything to anything else is a tough call unless something is both broken and unrepairable, or you can get something for a steal. The equipment costs is rarely going to pay for added efficiency of the system itself, unless the system is already toast. Now, if you are on propane, coal, oil, or resistive heat this obviously isn't true, but most of those systems were replaced in the 80s and 90s. If you have a home before 2000, you have natural gas heat and an AC. If your home is after 2000, it is a toss up between natural gas and heat pumps. So my natural gas furnace is from 1988, and is an 80% efficient system. It has had some work done over the years. The fan is clearly newer. The AC is from 2002-5. At some point someone added a 4" filter slot, and a UV light (which has never worked as long as I have been here). But the electronics and bulk of the unit is from the 80s. First winter here the furnace essentially never stopped, we closed all vents to the upstairs and unused rooms, and the air was horribly dry, and our heat bill was $500/mo+ in winter. It was awful, and we were cold. Several projects later, and in spite of rising fuel costs our Feb gas and electric bill, which is our worst for the year, was $250... And that includes about $30 worth of electricity mining on a couple Gpus. And we set the thermostat to 70*f pretty much year round, and we are now heating most of the basement and attic space. It has been a lot of work over many years getting our bill down that low, but our gas and electric bills have already more than paid for the improvements. So now I am looking at replacing a 35 year old system because we are obviously well beyond expected life expectancy. And picking what to choose is tough. Moving to a more modern 95% efficient system would be 15% off my monthly heat bill... So maybe saving me $200-250/yr? And moving from 2 window units upstairs and HVAC, so a single more modern and efficient AC is going to save an additional $2-300/yr. So let's be generous and say it would save us $550/yr for a $6k system. That would be a 12 year pay-off, for a modern cheap system expected to last 15 years. The thing would barely pay itself off by the time it is broken! And that assumes we scratch up the cash to pay for it outright. Add any kind of finance fees, and and that sucks. And if fuel costs rise dramatically during that time (as is somewhat expected), then that could really suck. Hardly an actual benefit to just riding this thing out and seeing if it can last 40 years! lol So then we look at heat pump systems. My initial looking tells me that they are going to be similarly priced around $6000 so that much is about the same. Overall operating costs though should be more significant savings closer to $750/yr. Now we are talking about an 8 year payoff, which is better, potentially worth financing, and should last the same ~15 years. However,ive heard horror stories about heat pumps in my area. My best friend had one in his last house that would freeze up outside because we hover around freezing, and the humidity and wild temp swings causes problems. I've heard similar issues from coworkers, where the ac is on in winter so the outdoor unit can thaw because it won't work without airflow. It is ironically better when we dip below and stay below freezing, which is rare. Hopefully newer units may not have the same issues? My friends newer home and heat pump appears to work just fine. And then there is the alt heat source. Most homes here with heat pumps use natural gas as the emergency heat sourse. And those who don't complain about very high electric bills with resistive heat. And that is a problem either way. Resistive heat means eating into the potential savings dramatically. Having even the option for gas backup means a $15/mo delivery charge just for the option to have it. And you could turn it off during the warm season, but the shutoff and turn on fees make that nonsensical. So I'd rather not pay $180/yr just for the couple weeks we might need emergency heat... Of course to remove gas it also means replacing our 1990s stove, and 2010 water heater... And I guess those are due for replacement anyways too soon. Then there is geothermal. In many ways the holy grail! Less need for emergency heat, making resistive heat less of a problem. Nothing to freeze up and cause trouble outdoors. Could save us closer to $1000/yr in energy bills. 5 years between inspections for most units. But the problem is price. It can be anywhere from $8-18k in my area... After incentives... Which I may or may not qualify for... such a range! And it doesn't depend on system size as much as labor costs. So it may be near the same price for a 2 ton unit as a 5, which is kind of crazy. And so few are done in my area that I can't get a straight answer unless someone comes out with either an appraisal fee or a high pressure sales pitch. If it is closer to the $8k price range, then it is a no-brainer move to do it as the added convenience and Lowe operating costs would bridge that $2k gap. If it is a $10k job it may be worth doing... But that is a lot of up-front scratch to come up with for hopefully a 10-12 year payback. $12k+ and the benefits become more murkey. I can deal with the grass being ripped out (heck, it would probably even out the lumps!). But like any investment, it is something that pays over time, so sooner is better than later... But saving up potentially $10k+ is going to take time that the current system may not have. If the current system dies tomorrow, it may decide for us lol. And the indoor equipment may still need replacement every 15-20 years like a normal system. But that future replacement should be significantly cheaper at least. And then there are minisplits to consider. Hyper efficient, long lasting, but high maintenance... And I'm lazy lol. Or rather, I'm forgetful! I use 3 month filters and am lucky to replace them every 4 months. The idea of needing to change filters and inspect the 6-8 small units my house would need... That doesn't sound like fun. It would save about $1k/yr in energy costs, and give more zoned options to keep bedrooms warmer or cooler in evenings while letting the larger open spaces have more temp variation. But at the cost of so much constant filter changes? Call me a baby, but that just isn't for me. It may make sense for the upstairs space where we need to redo duct work to make central air more effective.. But even that sounds horrible lol. I don't want to get busy and have a unit die prematurely because I'm an idiot. 1 central filter every 3 months is more my speed. I guess I am blessed by options... So I guess that is good? I'm just annoyed because there are so many other ways I would prefer to spend $6-12k than on an HVAC, and dealing with sales people, and contracts, and home construction. I should just thank my lucky stars that my 30+ year old heater is still running well. At least I am thinking about this now so I can potentially replace it on my terms rather than its terms, which would no doubt be the hottest or coldest day of the year.
Hi CaedenV, Thank you so much for sharing this! I really appreciate it. Yes, there are many options. So, it's good to be clear about goals. If you are looking for the cleanest, healthiest, most energy-efficient, and typically most cost-effective ways of heating and cooling your home, heat pumps are the way to go. One thing to consider is looking at the average worm and cold days rather than the coldest and hottest days, which is where auxiliary heating kicks in. Thanks so much and all the best. :-)
Great explanation. In the long term I think geothermal will win out on costs as economies of scale kick in reducing both the equipment cost and drilling/trenching services. Seeing how close it comes now while both are still fairly niche makes this almost a certainty.
@@NetZeroTech the only caveat for geothermal actually has nothing to do with geothermal. It is the quality of installation. In many places installers simply go by rules of thumb without putting in the necessary calculations involving soil moisture, ground thermal conductivity for different rock types, etc. This leads to poorly specified systems that most building inspectors lack the understanding to catch. This makes it a bit of a Wild West as with many new technologies. Carefully checking references beforehand can save thousands on remediation. One publicised bad install can undo to good of 25 great ones in public awareness and acceptance.
@@josephowens4654 So true, distorted perception through wrong publicity can cause a lot of unnecessary missed savings and emissions. And there is much more media coverage and attention to a much small number of cases in which something went wrong. Which is why I think that true, honest, and independent advice is of great value for everyone. This is one of the main reasons for the existence of this channel. It is a really great feeling to install a system, see the savings, improve the life quality, and reduce emissions. Helping someone to have this experience is truly rewarding. With economies of scale the level of optimization and quality of the systems will increase. The sheriff in the Wild West is gaining power.
Hi, 🙋♀️ Thank you! Much appreciated. Excellent question. To some extent. You can change the electricity price and see what that does to payback time. Fossil fuel prices have a higher volatility and are increasing overall as well. 💸 With solar PV ☀️ you can become independent of these prices changes. Yes, in the winter too with proper size and installation. Hope that helps. 😀
I think a civil engineer and you're general contractor determining how to dig the hole would disagree that it does take up a considerable amount of space during construction. You'd need to actually get the machinery into the area you plan to dig which is critical. Good financial modeling tho!
Thank you very much! Agreed! 👍 Since then, I have seen drillings that require very little space. I appreciate the compliment on the financial modeling. 😀
Hi John, that's amazing. 👏 Thank you so much for sharing! 🙏 Glad you can enjoy that significant reduction in your utility bill. Feeling more sustainable always makes me very happy. We moved to Wisconsin in April and currently rent a house. As the winter is coming closer, I'm thinking about installing a heat pump system here. We have air-source heat pumps for air conditioning. I need to talk with the owner. Perhaps we can make a cost-split deal. They have heat pump systems for rent in Europe, but the owner has to approve and order the system.
A vertical Ground Source Heat Pump (GSHP) typically reaches 200 - 600 ft into the ground. Horizontal loops are installed at about 3 - 6 ft. With respect to environmental impacts, I'd recommend looking at the MDPI article "Assessment and Minimization of Potential Environmental Impacts of Ground Source Heat Pump (GSHP) Systems". I hope that helps. Thank you. Katha
I am thinking to do open loop geo-thermal myself with 4000$ usd budget. I already have made tools to dug borewell with an worm gear electric drill. I wont be recording my progress but if anyone wants to discuss anything, please feel free.
@@NetZeroTech yes 20 years ago I installed a Water furnace heat pump it has been running ever since. My ground water is about 10c and I need a well for domestic use anyways so I made sure I had enough flow to supply my furnace. So electricity to run the water pump is the only other cost.
Thank you for watching and leaving a comment. Much appreciated. Feel free to check out some of my other videos. People have told me, they got better with time.
@@NetZeroTech I've subscribed and look forward to more from you in the future. I also shared this video with a couple of friends who also will find it informative. I'm in E. Texas with 5 acres and since I'm going to drain my small leaking pond (the soil is going to be great for geothermal but it's too porous for water retention) dig it a bit deeper (and enlarge it a bit) and now would be a good time to lay in geothermal water lines, cover with a pond liner, cap with a protective dirt layer and let it refill. I'm going to try to use a DIY of adding a automotive radiator to my HVAC ductwork and pump the low temp water through it to cool the household air during the summer. For wintertime I'm going to use the heat in the geothermal water to supply my heat pump AC unit by a commercial exchanger/condenser rather than the cold, heat poor air.

What happens when PV panels have to be replaced after 20 years? How do we take care of the hazardous waste - many heavy metals - in those systems? Batteries for the PV system? They don't last forever and that is a lot of mining to do. Nothing is free.
PV panels operate longer than 20 years. After 20 years the efficiency should be around 90% of their original output. Recycling solar panels is an interesting subject. I’d like to know more about it.
Ma'am you are very wrong if you think that Californians only pay 3 cents per kwh. You are defiantly cherry picking those numbers. In Northern California I pay 14¢ through 56¢ per kwh. Those go up after a very small base usage per month as well. I average $800 a month in the summer. How much do you pay?
Thank you for sharing. I think the US average at the time of recording was ~12 Ct. What is the usage (kWh) for that? Would you mind sharing which utility that is? Thank you.

Hi! Thank you for sharing. I'd have to go back and dig a bit deeper. I'm currently preparing a fix and flip. What would you like to prevent? Is it the daily load? it depends on the heat pump. Variable speed typically run 24/7, and that is actually a good thing, because preventing frequent turning off and on extends the lifetime. Thank you!
Hi, so, I think you are referring to ground-source heating based on the ground being heated by the sun. Geothermal heat is heat from the core of the earth. Which kind of heat is present at which depth depends on the thickness and layers of the earth’s crust. While Iceland is an obvious example of geothermal heat present under ground, it is present everywhere to varying extent. Hope that helps. Thanks for commenting.
Biggest thing I believe holding back geothermal heat/cooling is not the ROI math. Its that I can't show off to my neighbors how green I am with solar on my roof or how green I am by driving an electric car... Yet making my home more efficient as upgrading my A/C has a ROI of 4-5 years vs solars 10-20 years. Simply put, it's not sexy.
I think that's a very good point. I invested in a company selling air-source heat pumps and one of the things we discussed regarding pricing was how to make clean heating and cooling more showable. But it simply isn't as visible by nature. Perhaps someone seeing the comment has an idea on how to solve this. Thank you.
a ground sourced heat pump is used for the climate control in a building. geothermal is used to generate electricity, almost always on a grid scale. @@NetZeroTech
Thank you for noting. Yes, the name depends on the energy source. If the heat comes from the earth being heated by the sun it is ground source. The heat comes from the core of the earth it is geothermal. Good point. This depends on the earth’s crust in a geographic location, e.g. in Iceland it is geothermal right below the ground. Thank you! 🙏
This is an excellent commercial for alternate energy schemes but hardly a balanced systems engineering approach to decision making. For instance, should an 83 year old person "invest" in a systems with high up front costs? Its likely that the resale value of the house would not recover the investment. Second, and the most glaring omission is the projected life cycle costs. These ignore the very low reliability of various components and the necessary maintenance and replacement over the entire life cycle. It would be a mistake to ignore the downward spiral of compressor reliability and the switch to hazardous propane as a refrigerant that is lower in efficiency. The presentation suggests that once you pay off the initial cost that you are cost free thereafter. This is of course a marketing mind game that has been used many times in history so hopefully those considering investing will be more careful in evaluating their situation. Finally, consider obsolescence due to EPA mandates. In ten years your system may be declared irreparable. This is not a small risk.
Great points. Depends on the goal of the 83 year old person. If we're talking purely financially for themselves, some might invest in it for their kids. If we are talking contributing to reducing the sixth extinction, I'd say that is age-agnostic. I could provide some more info on reliability research. Would that be of interest? Thanks!
@@NetZeroTech I gather you believe in a sixth extinction and this rather than reliability is really your message. Change or perish. Thanks for clearing this up
If it requires an "incentive" it is by definition broken - we didn't need incentives to use smart phones, google or email - if it works, it doesn't need incentives, much less 26%
Thank you for taking the time to write several comments. Perhaps two things to consider with regards to incentives: First, most products have become economically viable once the subsidy were dropped since research and development have advanced to make the production cheaper in the meantime and market inertia has been overcome. A good example are solar panel systems. Second, unlike smart phones some products - usually infrastructural - benefit all citizens not just the person buying them, for instance through cleaner air. We could go further and start a discussion about the role of governmental regulation. It sounds like you tend towards Adam Smith's foundations of classical free market economic theory. After the great depression in 1929 John Maynard Keynes suggested the government could reduce the negative outcomes of wealth accumulation through stimulations. Today, stimulations also come from central banks in the form of quantitative easing. Thanks, Katha
@@NetZeroTech Almost all people today have at least a cell phone, if not a smart phone, so that analogy falls apart - especially when there are more smart phones than cars in the US. Solar hot water panels, hydrogen fuel cells, biodiesel - all were tried, subsidized and failed. Math always wins - regardless of ideology or what we would like and the math does not work for renewables PV still requires massive subsidies to justify CA is now undergoing a massive energy crisis because of its overreliance on an unreliable renewable energy. TX saw 189 people die in the cold snap - because of failed electrification policies - trading deaths for ideology is a soundly Communist idea - Mao would love it.
Sometimes subjects are being oversimplified. More than 8 million people died in 2018 from fossil fuel pollution. To stop heating and cooling altogether doesn’t appear to be desirable. Geothermal systems reduce the output we need for heating and cooling to a quarter of the input on average. New systems to a fifth. Is there anything I can help you with?
@@atenas80525 The incentives are a huge help with the initial cost of Solar or geothermal and they can take years off the break even point. In the long run, the 25 years for the solar output and lower operating costs in the case of geothermal will show big savings. The reality is these systems could likely be used for 40 years before they are replaced. For every system installed the long term energy savings will be quite high. I would like to hear from those that do have solar panels or Ground Source Heat Pumps what the anticipated savings is over the 25 year and 40 year period..
70's - solar hot water panels, 90's - hydrogen fuel cells, 2000's - biodiesel - now PV, wind and geothermal - every generation has their own fad that COULD work but when people actually have to use the math, it just doesn't work
Last year my home used 14,000KWh of electricity (Eversource) at .25 cents per KW for a total yearly cost of $3500. Today, on the Tesla solar panel website a system that produces 14,040 KWh is $33120 before any rebates. The equates to a 9.46 year break even time frame. With inflation - one might expect below an 8 year payback. In twenty years, the system will make 80% of the current KW. In current dollars the savings from year 10 to year 25 is $52,500 without factoring in rising electric costs or panel degradation. The assumption is they will cancel each other out. The math does work out over time.
@@Dave-tg1pu Batteries replaced 5-15 years Solar panels replaced 25 years Used panels are a hazardous waste and can't be recycled Rebates? Who pays that? some plumber or hair dresser is working to pay taxes to fund some suburbanite's environmental fad How many working people have an extra $33,000 to spend on solar panels? 25% of the population has 0 savings Most people are buried on the price of their house and cars and now groceries and gas If you live around wildfires, ash can reduce your generation to near zero Have to regularly clean the panels Plus, you still have to have a back-up source of electricity - what is that going to be?

We are about to have a vertical system installed by Dandelion in fact the drill rig will be here on Friday Aug 13th (yeah the old superstition). We are located close to Kingston NY and after a small heating oil leak decided to get out of the fossil fuel business! We checked out mini splits but found the maintenance on 6 interior units to be excessive not to mention the holes in the house walls for the refrigerant and drain lines. Dandelion designed a 5 ton system which requires two holes for the vertical loops. The house is 1920 sq ft and has an open design. We also had to replace the old hot air duct system as it was small and made from ductboard. After seeing the condition of the ductboard it was money well spent! Will update this comment after the drilling and install.
How exciting! Thank you so much for sharing! This is great. Good luck with the installation. Looking forward to that update a lot! 😀
@@NetZeroTech Today they finished drilling two holes 288ft. Very noisy for three days! Waiting for next phase which will be the trenching and going thru the foundation. Can't wait to remove the oil tank and oil along with the furnace.
@@chrismaxny4066 Great! Thank you very much for sharing. It sounds like the noisiest part is over. Good luck for the rest of the project. I'm sure it'll feel great to remove the oil tank and furnace. Exciting! I wish you lots of joy with the new system, the savings, the comfort, and the clean air, once it's installed. I'd appreciate hearing more. I think it would be interesting for others to learn about the next steps, the progress, and result of the project.
@@chrismaxny4066 Hi ChrisMax, How are you? Is your system installed? What has the experience been so far? I thought your previous comments where really interesting for others to learn from. Thanks again!
@@NetZeroTech We've been living with geothermal for three days and the cooling is phenomenal! Dandelion installed a 5 ton Aaon geothermal heat pump but we didn't get the desuperheater as our electric water heater is extremely efficient. However if your household has more than two people the desuperheater will be helpful in providing additional hot water. If you are in the northeast of the US Dandelion is without a doubt the best company to hire to install a geothermal system. All the people from initial contact to the final install and adjustments were respectful and helpful. Their quality of work and attention to detail is top of the line.
Our project involved upgrading our main electric panel to 200 amps and completely replacing the ductwork. We were very happy to so because an electric car is in our future and the ductwork was made of ductboard that was 30 plus years old. These two upgrades added $13,000 USD to the cost of the geothermal project but I consider them to be essential changes that would have been done at some point.
The entire experience of installing geothermal beyond the cost is more like an adventure. The process started with a phone call to Dandelion at the end of April 2021. We had the site survey in June which consisted of taking photos of the entire interior of the house with a 3d imaging camera so Dandelion could design the proper system for our home. Also the site for the drilling and trenching on our property was chosen. Dandelion actually wanted to start drilling in July but I put them off until mid-August which is when the drilling rig arrived. This was the part of the project that kept me awake at night. Both the neighbor's and my wells were very close (50ft) to the drill holes and as a precaution I had tested our wells before the drilling started. The drilling was extremely noisy, heard all over the neighborhood, and took two and a half days. This is the worst and most messy part of the entire project but also very interesting. Trenching to the foundation wall came next which was quiet compared to the drilling and not as bad as I expected. After reading what I consider a hit piece on Dandelion in Forbes magazine which mentioned cracked foundation walls caused by holes needed for the geothermal loops I was apprehensive! Turned out the foundation was just fine after drilling the holes but have the shopvac ready as there will be a lot of concrete dust blowing into the basement as the drill comes thru the wall. The rest of the install was a piece of cake and again Dandelion did an outstanding running the electric, connecting the loops to the geo heat pump, and finishing up cleaning the work site. The outside landscape was left in rough ready to be top soiled and seeded condition as per the contract.
The cost of just Dandelion's part of the project (all in USD) starting with the total: $40,375 - $1750 (discount for paying up front) - $9820 (incentive) Price before tax credit: $28,805 (what we paid) -$7489 (tax credit) Final Total: $21,316

How the excel sheet has calculated the breakeven point, Break even point is when the energy cost savings equal the amount of the upfront cost but here it is calvulated using the energy cost equals the upfront cost? I might be wrong with my concept, Can you have the explaination for it? Thank You for wonderful video!
Hi @DHRUMILKHATRI-br8mj,
Thank you for your feedback and looking into the calculations. I appreciate it.
So, for the electric heating with electricity from a solar panel system, the breakeven is calculated assuming that after the installation of the system (solar panel system or geothermal system), there is negligible electricity cost. This is true in case you have energy storage, e.g. in form of net metering or a battery bank. So, without inflation and time value of money, the system is paid down after the upfront cost matches the electricity cost equivalent that you would have paid for with electric heating and no solar panel system.
I'll try to update and document the assumptions on the breakeven calculations in the coming weeks.
What does your current heating and cooling system look like? Do you have a system in mind that you'd like to switch to?
Warm regards,
Katha

Your example location, Colorado, spends most of its energy budget on heating and not so much on cooling. But what of a desert area, such as Arizona, New Mexico,, Nevada, Texas, and high sierra areas of California? Yes, the desert gets cold at night, so heating is required, but cooling is often more than half the budget. How do the numbers work out there?

Geothermal can work great for cooling! In fact, you can DIY low-tech geothermal, if you can manage the excavations..that is the hardest part. Running fluid loops in the ground, harvests the earth’s mean-temp…that is approx. 55F., at about 6’ deep, most areas where people live.
The key to the thrift of running geothermal, is that equipment to heat or cool, only has to heat or cool maybe about 30 degrees different from the earth’s temp, but with an above-ground system, the devices must heat or cool a far bigger difference…if I want the house temp at 70F., and outside air is 32F., the machines must warm the house by close to 40 degrees. But a geothermal “preconditioning”, allows the machinery to only work to make about 20F….half the work.
Same for chilling….an AC unit must compensate the difference between say, a 100F. day, so must chill down 30F to reach the target temp. Or, a central HVAC must warm up a house from whatever the cold outside is…That costs energy. Hundreds, sometimes a couple thousand watts while on. States with more heating hours, or with more cooling hours, adjust their pricing units to cause higher costs for whichever one needs, to cost the most…those in heating climates, pay big energy bills to heat, but less to cool…and vice versa. Ya just can’t get ahead, with how systems have been rigged.
But really, if you want your house at 70F., geothermal-fed machines could feasibly only require the geothermal fluid temp with a fan blowing across the tubes in fins, only using enough energy to power the pump circulating the fluid, & the fan.
What if you had such a system (a low-tech geothermal) running 24/7, basically keeping the house at an average temp of the ground, & only adding the bit of auxiliary heat or cooling as needed? Combines regular heat & cool system, but adding a low tech geothermal, that only circulates fluid between ground to cooling fins with a fan blowing on it…maybe controlled by a thermostat, so it isn’t blowing ground-temp all the time, but enough to augment the regular system…THAT could be more easily retrofitted, though, there’s a little learning curve to it, it’s still very simple.
Hi Winter Star, That's right. Making use of the ground temperature helps to reduce the temperature difference between the house and its surrounding. The "low-tech" geothermal sounds like an interesting idea. Thank you for sharing!
I just had my pool (5.5m wide x 13m long x 1-3 m deep) removed and filled in. I very much wanted to lay down some loops, probably could have had 2 levels in the deep end. But even though the excavation was "free", I don't think I could have gotten more than a ton of capacity in that area, or in any event as much as I would need for my ~330m2 house. Also, I think the inspector and contractor would have made things difficult. Finally, even if that all shook out OK, maybe I would never use it for whatever reason. My other thought was just run some simple loop to cool a decent volume of air that I could bathe my AC condenser in when it's on. Would just be a small fan. But again, inspector and contractor would not want the hassle of understanding where I was coming from. In the end, I think it was some lost opportunity, but would have been not worth it or even be possible.
Yeah, sometimes practicalities make it difficult. Thanks for watching and leaving a comment!
Residential geo costs $3-5 per Watt. How many watts does a 2000sf home usually use?
Most US homes typically use 12 kW (3.4 tons). Most installers expect a 3 or 5 ton system to be most suitable in a residential home. Make sure to insulate well to avoid efficiency losses that can also arise from oversizing the system. In most cases, improving the insulation and then choosing a smaller system helps to reduce both upfront and recurring expenses.
My 4 ton waterfurnace 5 series, uses 2500 watts on stage 1 heating and 3000 watts on stage 2. Runs most of the day when under 30 degrees F
Do you have any comparison models for the north east/Connecticut?

Hi Steve, Great to hear you're going to install a geothermal system. Where you can get your geothermal system designed depends on your location. Heating and cooling is a fairly local business, since the system designer, who typically also wants to be the installer, would want to come by and take a look at the property. Some companies have locations in various states. Does anyone else have different thoughts? Thanks, Katha

@@CajunGreenMan Thank you for sharing! 🙏
Can you elaborate on the logic behind this "Additional Heating Required" assumption? Shouldn't this apply to both the electric heating and geothermal? The way I'm looking at it, if there are 65 days in a year where the clouds prevent enough solar to be generated for geothermal then the same should apply for electric heating from solar?
Hi Eaton, Thanks for commenting! 🙏 I'm sure many people have the same question. Many heat pumps in cold climates have a backup heat source known as auxiliary heat. Cold-climate heat pump technology has massively improved in the past years. So, many cold-climate heat pump models have become very efficient even at low temperatures that auxiliary heat is not required anymore. When the outside temperature is below 30 degrees, heat pumps with auxiliary heat auto-engage emergency heat to keep up with demand from the interior thermostat. Your heating system will then use the secondary system, e.g. an electric heat strip, with your normal heating. Electric heating systems do not have auxiliary heat, because they don't work more efficiently at lower flow temperatures (higher ambient temperatures). They essentially are in the less efficient and more expensive auxiliary heat mode at all times. I hope this helps and you are well. 😊 Happy holidays! 🎊 Katha

Same boat here... It is such a toss up!
A coworker moved from oil to normal heat pump, but it just isn't as 'warm' feeling... Which is a common complaint because heating the air is just not as warm feeling as the IR heating surfaces from the radiators. If the air is cool, but everything you touch is cold, you are going to feel cooler.
Another problem is that he is heavy on the emergency heat. So he is saving money... But not nearly as much as expected. He is looking at windows, insulation, etc to help with that. But again, a radiator heats surfaces more, so an oldish drafty house can still feel cozy. But switching to forced air makes drafts much more aparant.
If you are already on forced air, moving to geo thermal isn't going to feel much different. And most people on a forced air system are already going to have made improvements on drafts, and outright air leak problems before looking at any kind of heat pump system.
The other advantage of geo thermal is there is less need for emergency heat. Where we are at we are often right near the Frost transition. So it starts out raining, transitions to snow/ice, and you can get humidity build up. This ironically causes your heat pump to overheat as the airflow is cut off from the outdoor unit, and you then rely more on the emergency heat. So a defrost cycle is run, which means turning on the AC in winter to defrost the outdoor coils. Obviously some install choices can help with this, but it is a weirdly common problem, and can cause issues.
With geo thermal this just isn't an issue. There are no outdoor coils to freeze in the rain that need airflow. The coils are 6-8' under ground where it stays a nice cool 50ish degrees year round. So any heating you do is pulling 50*f ground up to 70 inside for a 30* temp difference. Or down from 90 oitside to 70 inside for a 20* difference. You aren't going from outdoor -10*f up to 70*f in winter. That is where the savings is. Emergency heat may still be needed if you can pump ground heat faster than your home is loosing it, but cutting drafts, insulating, etc can help that a lot.
I have a friend that purchased a house with a geo thermal unit he has had the compressor replaced ever 7 years and replace the unit once he hasn’t saved a dime after 20 years he is finely thinking about going back to natural gas

Do you have any suggestions on how the information of geothermal heating can get passed onto whatever NGO or Governmental Agencies that can build shelter for the refugee population from the Ukraine war? There are millions of Ukrainian refugees in Poland, and I fear nobody is thinking about how to provide heated shelter for those people when Winter arrives. Combining heat pumps with geothermal heating could heat housing for refugees without requiring enormous heating fuel costs. I wish such information could get to Habit for Humanity, or the European Union or the Polish Government so they can begin to prepare now for will otherwise become a greater human catastrophe than it is now. I might add a considerable amount of the workforce for the construction could come from the refugee population itself. Do you have any ideas on how to make this happen?
Hi Aristoctles. Indeed. Thank you for sharing. That would be a great synergy of addressing urgent humanitarian needs and the resulting temporary media coverage with the long-term need of humankind to eliminate greenhouse gas emissions. I'd have to look at the long-term impact of such a project more closely. The geographical shift in residential heating from Ukrainian refugees might be temporary and the focus and the required project resources might possibly be allocated better at higher impact projects on global greenhouse gas emissions. I currently help accelerate green hydrogen for heavy industries, which takes the bulk of my time. If anyone reading this wants to take a shot at sustainable refugee shelters, happy to connect you with folks in my network. 🙏

@@chrismaxny4066 Thank you very much for sharing your experience!
@@chrismaxny4066 Chris, now that you have had your system for nearly a full heating season I am wondering how heating with a GSHP is different from a NG furnace. For example, they say the heat output is more consistent but not a warm (air temp). Would you say your home is just as comfortable as in the past? Also, since I am considering a mini-split, do you think a modern model with 100% efficiency at -5% and 80% efficiency at -15% would be a good choice (in CT)?
Man... It is such a question.
Out here in Ohio natural gas is dirt cheap, as are electricity prices. So changing from anything to anything else is a tough call unless something is both broken and unrepairable, or you can get something for a steal. The equipment costs is rarely going to pay for added efficiency of the system itself, unless the system is already toast. Now, if you are on propane, coal, oil, or resistive heat this obviously isn't true, but most of those systems were replaced in the 80s and 90s. If you have a home before 2000, you have natural gas heat and an AC. If your home is after 2000, it is a toss up between natural gas and heat pumps.
So my natural gas furnace is from 1988, and is an 80% efficient system. It has had some work done over the years. The fan is clearly newer. The AC is from 2002-5. At some point someone added a 4" filter slot, and a UV light (which has never worked as long as I have been here). But the electronics and bulk of the unit is from the 80s.
First winter here the furnace essentially never stopped, we closed all vents to the upstairs and unused rooms, and the air was horribly dry, and our heat bill was $500/mo+ in winter. It was awful, and we were cold. Several projects later, and in spite of rising fuel costs our Feb gas and electric bill, which is our worst for the year, was $250... And that includes about $30 worth of electricity mining on a couple Gpus. And we set the thermostat to 70*f pretty much year round, and we are now heating most of the basement and attic space. It has been a lot of work over many years getting our bill down that low, but our gas and electric bills have already more than paid for the improvements.
So now I am looking at replacing a 35 year old system because we are obviously well beyond expected life expectancy. And picking what to choose is tough. Moving to a more modern 95% efficient system would be 15% off my monthly heat bill... So maybe saving me $200-250/yr? And moving from 2 window units upstairs and HVAC, so a single more modern and efficient AC is going to save an additional $2-300/yr. So let's be generous and say it would save us $550/yr for a $6k system. That would be a 12 year pay-off, for a modern cheap system expected to last 15 years. The thing would barely pay itself off by the time it is broken! And that assumes we scratch up the cash to pay for it outright. Add any kind of finance fees, and and that sucks. And if fuel costs rise dramatically during that time (as is somewhat expected), then that could really suck. Hardly an actual benefit to just riding this thing out and seeing if it can last 40 years! lol
So then we look at heat pump systems. My initial looking tells me that they are going to be similarly priced around $6000 so that much is about the same. Overall operating costs though should be more significant savings closer to $750/yr. Now we are talking about an 8 year payoff, which is better, potentially worth financing, and should last the same ~15 years.
However,ive heard horror stories about heat pumps in my area. My best friend had one in his last house that would freeze up outside because we hover around freezing, and the humidity and wild temp swings causes problems. I've heard similar issues from coworkers, where the ac is on in winter so the outdoor unit can thaw because it won't work without airflow. It is ironically better when we dip below and stay below freezing, which is rare. Hopefully newer units may not have the same issues? My friends newer home and heat pump appears to work just fine.
And then there is the alt heat source. Most homes here with heat pumps use natural gas as the emergency heat sourse. And those who don't complain about very high electric bills with resistive heat. And that is a problem either way. Resistive heat means eating into the potential savings dramatically. Having even the option for gas backup means a $15/mo delivery charge just for the option to have it. And you could turn it off during the warm season, but the shutoff and turn on fees make that nonsensical. So I'd rather not pay $180/yr just for the couple weeks we might need emergency heat... Of course to remove gas it also means replacing our 1990s stove, and 2010 water heater... And I guess those are due for replacement anyways too soon.
Then there is geothermal. In many ways the holy grail! Less need for emergency heat, making resistive heat less of a problem. Nothing to freeze up and cause trouble outdoors. Could save us closer to $1000/yr in energy bills. 5 years between inspections for most units. But the problem is price. It can be anywhere from $8-18k in my area... After incentives... Which I may or may not qualify for... such a range! And it doesn't depend on system size as much as labor costs. So it may be near the same price for a 2 ton unit as a 5, which is kind of crazy. And so few are done in my area that I can't get a straight answer unless someone comes out with either an appraisal fee or a high pressure sales pitch. If it is closer to the $8k price range, then it is a no-brainer move to do it as the added convenience and Lowe operating costs would bridge that $2k gap. If it is a $10k job it may be worth doing... But that is a lot of up-front scratch to come up with for hopefully a 10-12 year payback. $12k+ and the benefits become more murkey. I can deal with the grass being ripped out (heck, it would probably even out the lumps!). But like any investment, it is something that pays over time, so sooner is better than later... But saving up potentially $10k+ is going to take time that the current system may not have. If the current system dies tomorrow, it may decide for us lol.
And the indoor equipment may still need replacement every 15-20 years like a normal system. But that future replacement should be significantly cheaper at least.
And then there are minisplits to consider. Hyper efficient, long lasting, but high maintenance... And I'm lazy lol. Or rather, I'm forgetful! I use 3 month filters and am lucky to replace them every 4 months. The idea of needing to change filters and inspect the 6-8 small units my house would need... That doesn't sound like fun. It would save about $1k/yr in energy costs, and give more zoned options to keep bedrooms warmer or cooler in evenings while letting the larger open spaces have more temp variation. But at the cost of so much constant filter changes? Call me a baby, but that just isn't for me. It may make sense for the upstairs space where we need to redo duct work to make central air more effective.. But even that sounds horrible lol. I don't want to get busy and have a unit die prematurely because I'm an idiot. 1 central filter every 3 months is more my speed.
I guess I am blessed by options... So I guess that is good? I'm just annoyed because there are so many other ways I would prefer to spend $6-12k than on an HVAC, and dealing with sales people, and contracts, and home construction. I should just thank my lucky stars that my 30+ year old heater is still running well. At least I am thinking about this now so I can potentially replace it on my terms rather than its terms, which would no doubt be the hottest or coldest day of the year.
Hi CaedenV, Thank you so much for sharing this! I really appreciate it. Yes, there are many options. So, it's good to be clear about goals. If you are looking for the cleanest, healthiest, most energy-efficient, and typically most cost-effective ways of heating and cooling your home, heat pumps are the way to go. One thing to consider is looking at the average worm and cold days rather than the coldest and hottest days, which is where auxiliary heating kicks in. Thanks so much and all the best. :-)
Wow, so much great information. Thank you very much.
You are welcome. Glad it was helpful. :-)
Great explanation. In the long term I think geothermal will win out on costs as economies of scale kick in reducing both the equipment cost and drilling/trenching services. Seeing how close it comes now while both are still fairly niche makes this almost a certainty.
Great point! I agree. Looking forward to that development.
@@NetZeroTech the only caveat for geothermal actually has nothing to do with geothermal. It is the quality of installation. In many places installers simply go by rules of thumb without putting in the necessary calculations involving soil moisture, ground thermal conductivity for different rock types, etc. This leads to poorly specified systems that most building inspectors lack the understanding to catch. This makes it a bit of a Wild West as with many new technologies. Carefully checking references beforehand can save thousands on remediation. One publicised bad install can undo to good of 25 great ones in public awareness and acceptance.
@@josephowens4654 So true, distorted perception through wrong publicity can cause a lot of unnecessary missed savings and emissions. And there is much more media coverage and attention to a much small number of cases in which something went wrong. Which is why I think that true, honest, and independent advice is of great value for everyone. This is one of the main reasons for the existence of this channel. It is a really great feeling to install a system, see the savings, improve the life quality, and reduce emissions. Helping someone to have this experience is truly rewarding. With economies of scale the level of optimization and quality of the systems will increase. The sheriff in the Wild West is gaining power.
@George Mann You are right! Isn't GSHP 200-600 feet and geothermal about a mile deep on average? That would be 10X deeper. Thank you, Katha
@@josephowens4654
Absolutely Correct !!!!!
There is so much Conflicting Information out there !!- In All issuses
Great video! Does your break-even calculation take into account ever-rising electricity costs (at least in certain areas)?
Hi, 🙋♀️ Thank you! Much appreciated. Excellent question. To some extent. You can change the electricity price and see what that does to payback time. Fossil fuel prices have a higher volatility and are increasing overall as well. 💸 With solar PV ☀️ you can become independent of these prices changes. Yes, in the winter too with proper size and installation. Hope that helps. 😀
you make it seem like this is a brand new tech, but it's been used in homes for centuries
Yes, I agree. The only difference is that today the systems are safer and more cost-effective.
I think a civil engineer and you're general contractor determining how to dig the hole would disagree that it does take up a considerable amount of space during construction. You'd need to actually get the machinery into the area you plan to dig which is critical. Good financial modeling tho!
Thank you very much! Agreed! 👍 Since then, I have seen drillings that require very little space. I appreciate the compliment on the financial modeling. 😀
Geothermal is the best especially with solar panels Was paying 400Now pay $147Thank you Gio
Hi John, that's amazing. 👏 Thank you so much for sharing! 🙏 Glad you can enjoy that significant reduction in your utility bill. Feeling more sustainable always makes me very happy. We moved to Wisconsin in April and currently rent a house. As the winter is coming closer, I'm thinking about installing a heat pump system here. We have air-source heat pumps for air conditioning. I need to talk with the owner. Perhaps we can make a cost-split deal. They have heat pump systems for rent in Europe, but the owner has to approve and order the system.
How deep do you need to drill? What happens if you hit ground water?
A vertical Ground Source Heat Pump (GSHP) typically reaches 200 - 600 ft into the ground. Horizontal loops are installed at about 3 - 6 ft.
With respect to environmental impacts, I'd recommend looking at the MDPI article "Assessment and Minimization of Potential Environmental Impacts of Ground Source Heat Pump (GSHP) Systems".
I hope that helps. Thank you. Katha
I am thinking to do open loop geo-thermal myself with 4000$ usd budget. I already have made tools to dug borewell with an worm gear electric drill. I wont be recording my progress but if anyone wants to discuss anything, please feel free.
Great. Thank you for sharing. Best of luck. And joy in the process. I‘d be curious to see how it goes. Thank you, Katha
Very interesting and useful. Thank you for sharing :)
Glad to hear! Thank you for watching.
You only priced out closed loop which is way more expensive than open loop if you have the necessary available resources.
Hi, Thanks for the note. What is your estimate for open loop?
@@NetZeroTech cost of the furnace plus water pump likely less than 1/4 of the closed loop because of drilling or digging
@@offgridwanabe Interesting. What's the catch? Have you installed one of these systems?
@@NetZeroTech yes 20 years ago I installed a Water furnace heat pump it has been running ever since. My ground water is about 10c and I need a well for domestic use anyways so I made sure I had enough flow to supply my furnace. So electricity to run the water pump is the only other cost.
@@offgridwanabe Sounds great! Well done! 🙂

@@NetZeroTech I've subscribed and look forward to more from you in the future. I also shared this video with a couple of friends who also will find it informative.
I'm in E. Texas with 5 acres and since I'm going to drain my small leaking pond (the soil is going to be great for geothermal but it's too porous for water retention) dig it a bit deeper (and enlarge it a bit) and now would be a good time to lay in geothermal water lines, cover with a pond liner, cap with a protective dirt layer and let it refill. I'm going to try to use a DIY of adding a automotive radiator to my HVAC ductwork and pump the low temp water through it to cool the household air during the summer.
For wintertime I'm going to use the heat in the geothermal water to supply my heat pump AC unit by a commercial exchanger/condenser rather than the cold, heat poor air.
@@bobjoatmon1993 That's great! Thank you very much. I appreciate it. Sounds like a great project. Thank you for sharing. It would be awesome to hear how it goes. Perhaps you can take pictures or a video and tell us about it if you like. Good luck!
2:49 "Fact 5: Description"
Apologies. We can't edit in retrospect. Just introduced a review process to avoid this. Thank you for noticing!
What happens when PV panels have to be replaced after 20 years? How do we take care of the hazardous waste - many heavy metals - in those systems? Batteries for the PV system? They don't last forever and that is a lot of mining to do. Nothing is free.
PV panels operate longer than 20 years. After 20 years the efficiency should be around 90% of their original output. Recycling solar panels is an interesting subject. I’d like to know more about it.
Ma'am you are very wrong if you think that Californians only pay 3 cents per kwh. You are defiantly cherry picking those numbers. In Northern California I pay 14¢ through 56¢ per kwh. Those go up after a very small base usage per month as well. I average $800 a month in the summer. How much do you pay?
Thank you for sharing. I think the US average at the time of recording was ~12 Ct. What is the usage (kWh) for that? Would you mind sharing which utility that is? Thank you.
Outstanding breakdown. Thank you!
Thank you very much. 🙏 I appreciate it and hope it helps. Have a great week. 😊
i disagrees on the life of a heat pump you mention ( source) . the compressor and electronics operate 24/7 . simple research on hvac company web sites , counter your "suggested " life . plus the the top end units , there 3-4 avg computer board are $ 1500 - 3k each to replace . If a home needs geo thermal , the design team missed the opportunity in the build / shell phase . the roi on home / commercial shell efficiency construction, spanks the , after thought of efficiency after , the build phase. reduce the daily load . good on you for education . what about prevention ?
Hi! Thank you for sharing. I'd have to go back and dig a bit deeper. I'm currently preparing a fix and flip. What would you like to prevent? Is it the daily load? it depends on the heat pump. Variable speed typically run 24/7, and that is actually a good thing, because preventing frequent turning off and on extends the lifetime. Thank you!
i wish i knew why everyone refers to it as geothermal when it has NOTHING to do with geothermal heat.
Hi, so, I think you are referring to ground-source heating based on the ground being heated by the sun. Geothermal heat is heat from the core of the earth. Which kind of heat is present at which depth depends on the thickness and layers of the earth’s crust. While Iceland is an obvious example of geothermal heat present under ground, it is present everywhere to varying extent. Hope that helps. Thanks for commenting.
Biggest thing I believe holding back geothermal heat/cooling is not the ROI math. Its that I can't show off to my neighbors how green I am with solar on my roof or how green I am by driving an electric car... Yet making my home more efficient as upgrading my A/C has a ROI of 4-5 years vs solars 10-20 years. Simply put, it's not sexy.
I think that's a very good point. I invested in a company selling air-source heat pumps and one of the things we discussed regarding pricing was how to make clean heating and cooling more showable. But it simply isn't as visible by nature. Perhaps someone seeing the comment has an idea on how to solve this. Thank you.
You're joking, right?
@@jamesharper8373 nope unfortunately.
Fantástico!!!
Obrigada!
😀😀😀
😀😀😀
you seem to be conflating ground sourced heat pumps & geothermal power plants. these are NOT the same thing.
My apologies, if that is the case. Do you roughly remember which minute? Thanks!
a ground sourced heat pump is used for the climate control in a building. geothermal is used to generate electricity, almost always on a grid scale. @@NetZeroTech
You are using the wrong term. The term you should be using is "ground source". There's a big difference between these technologies.
Thank you for noting. Yes, the name depends on the energy source. If the heat comes from the earth being heated by the sun it is ground source. The heat comes from the core of the earth it is geothermal. Good point. This depends on the earth’s crust in a geographic location, e.g. in Iceland it is geothermal right below the ground. Thank you! 🙏
This is an excellent commercial for alternate energy schemes but hardly a balanced systems engineering approach to decision making. For instance, should an 83 year old person "invest" in a systems with high up front costs? Its likely that the resale value of the house would not recover the investment. Second, and the most glaring omission is the projected life cycle costs. These ignore the very low reliability of various components and the necessary maintenance and replacement over the entire life cycle. It would be a mistake to ignore the downward spiral of compressor reliability and the switch to hazardous propane as a refrigerant that is lower in efficiency. The presentation suggests that once you pay off the initial cost that you are cost free thereafter. This is of course a marketing mind game that has been used many times in history so hopefully those considering investing will be more careful in evaluating their situation. Finally, consider obsolescence due to EPA mandates. In ten years your system may be declared irreparable. This is not a small risk.
Great points. Depends on the goal of the 83 year old person. If we're talking purely financially for themselves, some might invest in it for their kids. If we are talking contributing to reducing the sixth extinction, I'd say that is age-agnostic.
I could provide some more info on reliability research. Would that be of interest?
Thanks!
@@NetZeroTech I gather you believe in a sixth extinction and this rather than reliability is really your message. Change or perish. Thanks for clearing this up
If it requires an "incentive" it is by definition broken - we didn't need incentives to use smart phones, google or email - if it works, it doesn't need incentives, much less 26%
Thank you for taking the time to write several comments. Perhaps two things to consider with regards to incentives: First, most products have become economically viable once the subsidy were dropped since research and development have advanced to make the production cheaper in the meantime and market inertia has been overcome. A good example are solar panel systems. Second, unlike smart phones some products - usually infrastructural - benefit all citizens not just the person buying them, for instance through cleaner air. We could go further and start a discussion about the role of governmental regulation. It sounds like you tend towards Adam Smith's foundations of classical free market economic theory. After the great depression in 1929 John Maynard Keynes suggested the government could reduce the negative outcomes of wealth accumulation through stimulations. Today, stimulations also come from central banks in the form of quantitative easing. Thanks, Katha
@@NetZeroTech Almost all people today have at least a cell phone, if not a smart phone, so that analogy falls apart - especially when there are more smart phones than cars in the US.
Solar hot water panels, hydrogen fuel cells, biodiesel - all were tried, subsidized and failed. Math always wins - regardless of ideology or what we would like and the math does not work for renewables
PV still requires massive subsidies to justify
CA is now undergoing a massive energy crisis because of its overreliance on an unreliable renewable energy.
TX saw 189 people die in the cold snap - because of failed electrification policies - trading deaths for ideology is a soundly Communist idea - Mao would love it.
Sometimes subjects are being oversimplified. More than 8 million people died in 2018 from fossil fuel pollution. To stop heating and cooling altogether doesn’t appear to be desirable. Geothermal systems reduce the output we need for heating and cooling to a quarter of the input on average. New systems to a fifth.
Is there anything I can help you with?
@@atenas80525 math becomes irrelevant when externalities are disregarded to suit ideological preferences.
@@atenas80525 The incentives are a huge help with the initial cost of Solar or geothermal and they can take years off the break even point. In the long run, the 25 years for the solar output and lower operating costs in the case of geothermal will show big savings. The reality is these systems could likely be used for 40 years before they are replaced. For every system installed the long term energy savings will be quite high. I would like to hear from those that do have solar panels or Ground Source Heat Pumps what the anticipated savings is over the 25 year and 40 year period..
70's - solar hot water panels, 90's - hydrogen fuel cells, 2000's - biodiesel - now PV, wind and geothermal - every generation has their own fad that COULD work but when people actually have to use the math, it just doesn't work
In some market conditions the technologies you mention are economically viable. Failure is part of evolution.
Last year my home used 14,000KWh of electricity (Eversource) at .25 cents per KW for a total yearly cost of $3500. Today, on the Tesla solar panel website a system that produces 14,040 KWh is $33120 before any rebates. The equates to a 9.46 year break even time frame. With inflation - one might expect below an 8 year payback. In twenty years, the system will make 80% of the current KW. In current dollars the savings from year 10 to year 25 is $52,500 without factoring in rising electric costs or panel degradation. The assumption is they will cancel each other out. The math does work out over time.
@@Dave-tg1pu Batteries replaced 5-15 years
Solar panels replaced 25 years
Used panels are a hazardous waste and can't be recycled
Rebates? Who pays that? some plumber or hair dresser is working to pay taxes to fund some suburbanite's environmental fad
How many working people have an extra $33,000 to spend on solar panels?

The only thing you need to know about geothermal is that air source heat pumps can work down 31 F
In terms of efficiency, geothermal heat pumps are superior to air-source heat pumps in most cases due to the stable temperature below ground. A video comparing the systems is on my list of future videos. Please subscribe if you'd like to be notified. Thank you!
