I must have missed it but it looks like there is no driptray and floorwaste in your utility room also i prefer to run surface mounted piping in copper which makes for a neater appearance that pex looks like spaghetti thrown on the wall old school plumber here anyway still like your videos 👍
In 1975 we built a home in Iowa and had a heat pump installed. It worked wonderfully for the 28 years we lived in the house and the present owners are still using this system today 48 years later. They have had to replace some parts but nothing major. We moved to Arkansas in 2003 and had a heat pump installed in our new home there, and 20 years later it is still working. Cannot say enough good things about this product. Economical, reliable, comfortable winter and summer....it also did the air con in summer. I am sure there have been improvements made since our install in 1975 but all to the good I am sure. Great job!!!!!
Congratulations on your new conveniences! Hopefully all your hard work brings you to an easier existence, realizing of course you have lots of projects yet to accomplish, but hopefully with less stress. So happy for you guys, onwards and upwards!
Re having exposed piping, it all looks so neat and orderly that I'd be proud to show it off! Re depending on solar panels for power, there would probably be enough heat stored in the tank to keep the house comfortable on a winter's night even if you shut off the heat pump until morning. But you won't have to, because batteries have improved to easily provide power to the compressor for many hours. Ten years ago this system would have been risky, but solar cells, batteries and air-sourced heat pumps have all become vastly more efficient since then.
Yes, we’ve thought of this too (hence the test to see the temp drop when turned off) and during periods of grey days we’ll probably turn the unit off to preserve the power in the batteries. We also have a backup generator but really want to avoid using it.
I am wondering why the ventilation pump has to be turned off for the day time. I have heard that in England, for example, it is customary to heat the apartment in the evening and at night for a while, and during the day the apartments are kept cold. This results mold damage inside of house. In my country, it is customary to keep the house heating, also the ventilation pump always on, to avoid mold damage. The ventilation pump has a thermostat that keeps the desired room temperature constant. The air heat pump should be adjusted to 23 or 24 degrees in hot weather and then keep it on all the time. Also, the humidity outside does not move inside the house when the ventilation pump is constantly on. As we all know, moisture always moves from wet to dry, which in turn worsens air quality and causes mold damage at worst. If we switch off the device continuously, there is moist air outside and dry air inside, the moisture seeps through the structures. There will be no problems if the machine is on all the time, with a suitable coolness and the indoor air is suitably dry. The air source heat pump is kept on even on working days, even if there is no one at home and when we go on vacation. The ventilation pump is easily damaged by being turned off and on constantly. (Executive director of Sulpu ry, the Finnish heat pump association, Jussi Hirvonen.)
@@vrvrhm8438 On a good insulated house you do not need to power off the heating. We have it all day long turned on and the consumption is quite low.Of course you are required some double/triple glazing and quite thick insulation layer for that.
I live in USA and all my pipes in the utility room are exposed. That’s how the house came it wasn’t something I chose. Who would want to have to dig the pipes out of the walls in an emergency situation when you have a leak and have to get to one of the pipes. Your pipes look very well organized and covered and labeled nicely. It’s not like you are serving dinner in there. Great job.
Congratulations! Not just for the hot water, cold water and electricity, but also for them being housed in a room with very good looking walls and floor! You guys are amazing.
Easiest way to describe a air heat pump is it's like a fridge but in reverse. In Sweden these heating systems are quite popular in (as you state) existing buildings since being relatively easy to install. If these systems work in Sweden they should be working better in Portugal. The data of your off-grid system would be very interesting, I dont beleive that would work in Sweden considering the short daytime (sun hours) during winter months wich is the period the system is needed the most. Final comment, Connecting the woodburner is smart, making use of the cosy fire in more ways then one. Thanks, guys!
Expansion tank is to equalise pressure as the temperature rises and the water expands. Water expands slowly with temperature - hence the small equalisation tank 😁
Yes. Traditionally in a one story dwelling the expansion of the water is relieved by a vent pipe which goes through the ceiling and roof space and extends above the roof line. As the water expands it will move up this pipe. More commonly now the pressure is relieved by a valve and pipe that's vented under the house. As this house has no underfloor space and the roof line is so far above the hot water tank, the expansion tank is installed to accommodate the expansion of the water.
@@Brigidz In central Europe you frequently have a pressure relief valve at the cylinder that vents into a drain every time the cylinder heats up. More recently I've started seeing DHW expansion vessels like in this system (you can tell it's for the domestic hot water because it's grey, central heating ones are red, not safe for drinking water). This vessels is divided into two halves by a membrane. One half is full of water, the other air or pure nitrogen. Water doesn't compress, so as it heats up its volume increases. Gases do compress so with half the vessel filled with a gas the water has somewhere to go. As the water volume increases the gas is compressed and once the pressure is relieved (e.g. because you open a tap somewhere) the gas expands again. Works fine until the membrane gets old and brittle but these things are cheap. The wood burner needs a different kind of equalisation. If you've got, say, a gas burner you can simply shut off the gas as the thermostat says the water in the cylinder is hot enough. If your heat source is a wood burner you can't do that, the fire will continue to burn for a while and the heat that generates needs somewhere to go, otherwise your back boiler could explode (that does happen if such a system is incorrectly installed, I think several people were killed in such an incident in Austria a few years ago), so you need a big water tank that can take the heat. 300 l is small for that, I tried to find figures a while ago and got something like 600 l for the smallest pellet burners.
Water also contains a lot of diluted air and when heated expands so that is also i believe sorted by the expansion tank and vent valves. A boiller like a wood burner that can generate very high temperature and might be difficult to control needs the expansion tank. While a system like a heatpump that will keep the water temperature and pressure under tight control, can do without it.
I live in Sweden and have an air/air heat pump to heat the 112 sq. m. house(no hot water) and it can still keep the inside temperature at 20 C when it is -20 outside.
Like every other subscriber to you, I share your excitement! It is a little odd that I find it fantastic and wonderful that a house in Portugal, belonging to people I don't REALLY know, has got an air source heat pump, water and electricity. But I am delighted. On the otherhand we know you, we know how hard you have worked to get this far, we appreciate your well made videos showing the mistakes as well as the successes. It is odd. I might meet you in an airport one day and see a couple I know as 'friends' with very similar views to me but you barely know I exist. I wouldn't dream of writing similar to Taylor Swift or David Attenborough, but isn't it broadly similar? Do you have bodyguards when you go to the supermarket, or send minions? (tongue in cheek) (Small aside, I genuinely bumped in to Angelina Jolie and Brad Pitt in my local supermarket some years ago, shopping for themselves without 'security')
First, congratulations on this monumental achievement and quality of life advancement! Second, evidently a lot of the rap on heat pumps is fossil fuel industry disinformation. The NYTimes and the Washington Post have both done extensive coverage on heat pumps during the past several months, for anyone interested. In particular, there’s a WaPo article from Feb. 7, 2023, about how heat pumps are working great even in chilly Maine, and all the oil industry panicky pushback. And there’s an NYT article from Feb. 22, 2023, about how well heat pumps handle the cold (tl;dr, they do have to work harder in cold weather, but they’re still more efficient than fossil fuel-run furnaces and boilers). Third, they can be used to cool homes too, which will probably be of increasing interest to everyone.
I think the same is the case in the UK, bad mouthing from the gas industry (most central heating is via gas boilers). Hopefully over time as more positive case studies energy the general public will become better informed. Our system can also run the radiant system in cooling mode. I’ll be interested to test this and see if there’s any resultant condensation on the floor
Pls keep in mind a few variables need to be in your favour to make best use of such system. For instance low cost electricity, the ability to install on your property (space, pipes) and location. It's much more challenging to upgrade eg apartment buildings, buildings with poor infrastructure, areas with high electricity cost etc. I'm not a fossilist 😂 i own a solar powered property in the Algarve with electric, floor heating battery storage and electrical vehicles.
Looks great! I can support your intuition that your air-water heat-pump together with the solar PV modules, provided you have enough battery capacity, will make you through the winter. We live in south Germany, near the Alps and, on average, we have some 10-12 weeks with temperatures below zero, and from those we have 2-3 weeks where the outside temperature is below -10ºC 24/24h. We have also underfloor heating, and an air-water heat-pump with a 750 liter tank. The heat-pump struggles on those "below -10ºC" days, where the efficiency really drops, mostly due to the fact that the cycle must reverse several times per day to unfreeze the outdoor unit. It is not perfect, but 10 years ago the technology was not as evolved as today. On our case a geothermal heat-pump would be the ideal choice, but the original builder/owner did not considered it at the time of the construction works... We also have a 18kWp solar array with a total of 18kWh battery capacity, which provides us with 85% autonomy/year (we just need some external sourcing from the public network between November and March, mostly when the roof is covered with snow). So, with the portuguese climate and proper sizing of the solar power system, you will for sure be fine, even without the wood burner. We are also planing our move back to Portugal in a few years time, and I am still somewhat hesitant between an air-water and a geothermal heat-pump. So I'm eager to see the data you will be collecting from your set-up. Keep on the good work!
You both must be over the moon happy with this milestone!! You both are creating a home masterpiece. Enjoyable to watch your progress from time to time.
Awesome accomplishment friends! Love seeing your progress ! You certainly have worked so very hard! I am glad you can get into your house! You may want to consider solar back up, as you age wood heating is a lot of work! A little of both?! Anyway, take a good holiday so you stay healthy!👏👍😁Your bodies deserve it! The house will be there in 3 days😜👍😁👏❤️ I really love the detail that you go into with your building projects! You work so well together! So take good care of yourselves! You are doing a lot! I just moved into a small home in Maine! I do oil paintings and after caring for my husband who had Alzheimer’s, I am now able to enjoy life again! Rich made 90👍👏 and we got through a very stressful time for 6 years with his passing at 90! So health is important! I see you wear breathing protection! 👏 Keep safe and healthy and hopefully , you can start to enjoy living in your Portuguese home! It ‘s certainly going to look lovely with your care! Hopefully your garden will feed you through the years to come!👏👍🍋😁❤️👏
I live in Switzerland and built a wooden house with passive energy level. I do have an air based heat pump and it works perfectly. The systems works because any temperature over 0° Fahrenheit (helps to understand better) is physically "warmth" or "energy". So also when here in winter there are - 20° Celsius, it does its work. Only problem I encounter is that whenever the temperature drops quickly, the pump needs a bit of time to heat up. So I have a wood stove and a fire place that I use in those cases to warm up the house for the max. 1 day until the heat pump is again on full mode. Congrats to your milestone!!!
ASHP will be fine off grid. Anyone saying otherwise it wrong. You’ve got underfloor and good insulation, solar and some battery storage. It will work fine. You won’t even need to use your back boiler (although it will be cozy to have the fire going) System looks amazing. Looks like you’ve covered all angles. I look forward to seeing update videos on the performance 👍🏻 congratulations
The only thing we’re a little concerned with is the number of grey days that won’t produce much power. Last winter (which was the worst for this are in a very long time), there were 40 days when we weren’t producing any power and had to use a generator. We’ve beefed up both panels and batteries, but it’s always good to have multiple backups 😀 Plus, who doesn’t love sipping wine by a fire 🤣
@@MAKEDOGROW Glad I made you laugh. Frankly, this is the best time to install a heating system, and your installation so far looks excellent! We have a log boiler and radiators waiting on the plumbers leisure. I hope we can get it all completed by winter. Ours will be log fired with vacuum tube solar for summer hot water.
@@SailingCartagena yep, this is one of the reasons we got it done now … virtually nothing happens in July/Aug and we didn’t want to risk having it installed in the run up to winter
€12,000 is a good price for all the equipment and installation. Yes, the heat pumps do run off solar alone, the converters are the keys. The heat pump looks very similar to the ones in Canada that heat a 1,000 sq. m home with the proper windows, doors, and insulation. Excellent job those guys did, tidy, easy to access. Enjoy! You both deserve it. 💦
@MAKDOGROW the heat pumps are being delivered, used in a lot of places now during renovation. They work well as far North as Edmonton, Alberta which can get to -35. The fossil fuel industries have tried to keep people away from both solar, mini turbines and heat pumps. 😡 The number of EV trucks, cars is getting to be far less noticable because there are now so many on the roads, wonderfully quiet. Canadian Permaculture Legacy has a video showing how much money is saved by driving an older Tesla, something like $7,000/year!
The room is a mechanical room and you should be proud of yr work & yr vendors, why go covering the craftsmanship, the neatness and well laid design given yr constrains, its a wonderful marvel you have created. I say don’t cover the pipes etc …. SHOW what you have done, stand tall n happy 😊🎉
First time I've heard of, much less seen, an air supplied heat condenser. I had a friend who ran an outfitter business up in Canada who installed (by himself, as I gather) an underground heat collector/condenser system and it kept them warm and snug at -59 F during the winter with no need to run a wood stove to augment it. So I know that worked in extreme conditions and am looking forward to see how your system works in a moderate climate. Clear explanations are priceless and you both hit the mark spot on. Thanks---and I'm looking forward to your next episode with whatever you have on the hob.
Air source heat pumps are being used a lot throughout Europe and are even widely-known here in the UK where there is a government not well-disposed to renewable technologies. There's certainly a lot of garbage being pushed about them in our media.
I think the most easily understood concept of air source heat pump was a domestic fridge. The fridge maintains a colder air temperature than ambient air and the compressor etc pumps the energy out as heat through the radiator at the rear as heat. Effectively identical as your underfloor heating pipes. You'll find that the air source heat pump will work over a wide range of temperatures however as the temperature drops the efficiency will change. So,whilst you'll still have heating You'll not get the suggested 3:1 ratio
The expansion tank is for keeping pressure differential stable while the water heats up. This one is just for the expansion of water in the boiler. You really need a bigger seperate expansion tank for the water in the underfloor heating because when the temperature of the water is low and the heat pump starts the pressure drops and the flow rate decrease until it gets the setup temperature. This slows the heat transfer. It is also usefull to use a different tank as a buffer tank from the unit to the underfloor heating so the compressor of the heat pump doesn't open and close many times. An engineer can take a look on this.
Be aware that 45 degrees is in the ideal range for legeonella to multiply. If you are not planning to use too much water it will exacerbate the risk. The water must be heated above 50 degrees to kill the bacteria. Best wishes
A friend of mine had a air sourced heat pump for his outdoor swimming pool. He put a poly shelter over it so that it could be used all year round, the amount of heat within that cover seemed extreme so we installed ducting so that the heat pump could recycle the warm air to heat the water. It worked a treat.
We run a similar set-up here in the U.K. - solar PV powering our Daikin ASHP for UFH and hot water. Our climate is considerably colder but we are still getting an annual average COP of 3.
Nice! I doubt we can achieve a 3 yet (with leaky doors/windows, no insulation upstairs, etc) but it will be super interesting to watch this winter and see things improve over the years as we get closer to a finished building
We installed an air sourced heat pump 20 years ago but unfortunately at that time time there were numerous compressor issues, so that eventually after some years of repair and replacements, which the company were happy to do, we switched to solar generated electricity with a standard tank. We are in Australia and the compressors were only produced on the west coast and had to be transported all the way to the east coast. When it did work it was great. So glad the technology has caught up with the vision. We now have a new technology installed within the tank system that stores the unused solar power for times when sunlight isn’t available (that would be at night 😁).
Love the idea of the wall mount. It wasn’t suggested when we installed our split system. One suggestion, take pictures of each area, print them off and write very detailed of what pipes and tube go where and how they are run. Your memory now is wonderful, but a few projects down the line our memories get a bit blurred. This saved us a big headache when I decide to run the water to the laundry room a bit different…didn’t do it as it won’t have cut off the water to the powder room!
Great job on the prep work and the heat pump install. I'm looking forward to the video on the ventilation installation. I know the brand of ductwork you're using. 5 tips here. 1. Don't save on the number of ducts. If the duct identifier says AE34, you should not use it for more than 34m³/h per duct. AE48 is 48m³/h and so on. 2. Don't make the ducts too long and avoid unnecessary bends. A rule of thumb is: the outer diameter in cm is the maximum length in meters if you use it for the maximum flow rate (tip 1). 3. Avoid any bends really close to the collectors. If there is residual tension on the duct going into the collector they could leak. 4. Look at the instructions in the box of the collector. These are great. 5. The manufacturer has superb graphs on the combination duct size, length, and pressure drop. Use those to make a detailed pressure drop calculation based on your ductwork layout plan.
Wish I could get guys that do that kind of clean work here in the US. Small tip - pass-throughs in exterior walls and foam insulation around piping attract mice, so stuffing in a layer of copper wool on the outside prevents mice from chewing and squeezing their way in.
Wow, you both won’t know what to do with all your new stuff, you both work so very hard, we look forward to your videos all the time, so many changes and the difference, it’s really coming along, your going to have a fantastic home at the end. How’s the chickens doing? Haven’t seen them for while, and how many kittens did you keeps ? 😅
Love the way you have curved the area around that small window. I have a 1930s house in Melbourne Australia which is double brick and all the windows have that curving or rounded edge which softens the light coming in to the house.
One tip if i may ,attach a pipe or a hose to the pressure release valve to direct the water outside or in to a bucket because the last thing that you want is for something to go wrong and the pressure to rise to the point that the valve opens ( and instead of saving your system )dumping water all over your heat pump potentially creating a short ask me how i know
Yep, once we have the waste pipe installed we’ll run into that. We also need to add a pressure relief valve to the ufh manifold and run a pipe for that too (we weren’t aware we needed that until the guys did the install)
Heat pumps still work just fine below zero. We use them in Japan year-round, and many other countries are similar. The efficiency issue is mostly caused by the defrost cycle that's needed in freezing temperatures, but still it's more efficient than electric resistance heating.
I think you have an angel watching over you….min 9:38 when you’re explaining about the “misconception of the heat” - a wisp of light floats from above your left shoulder / right corner of window…and it makes sense when talking about “energy”. Just something Interesting. Love your channel!
First of all, you both look less stressed in this video. I have Daikin and I live in Italy. in the mountains. It snows maybe one day a year. So not too cold. My electric bill is not outrageous and the heat and AC work very quickly and are efficient. I have hot water on demand. I have replaced all my windows and doors with double insulated and my house is cozy. I have a ground floor cantina which I heat with a small pellet stove. I do not have solar, sadly. But most of our village is run on Wind power. I am so happy for you both to have your heating, water and flushing toilets. Bravo to you both.
I live in the U.S.A. and have a forced air heat pump for heating and air conditioning. Winters average -6 C and very hot summers 32 to 37 C or more on occasion and I am very happy with my heat pump.
Congratulations! We have the same system. So solar and Air source heat pump. We have a Panasonic Aquarea. It's just amazing. No underfloor heating just conventional iron radiators. We have a large Stone Bastide and adjoining gite for anyone that doubts you can put in old buildings! Insulation is crucial. Its currently 29 degrees outside (I am in the south of france) and the house is a consistent 20 all . year round. We have a wood burner to chug up the direct heat in the winter. You will find that you will have more hot water than you can even imagine. We can have a houseful and gite full and everyone can have showers. we have two dishwashers; two washing machines and we have never run out. We find it runs really well in the winter and we get down to minus 10- 15 in the winter. Panasonic have a model called T cap which functions normally in extreme cold weather.
Legionella may be a risk though if you keep it at 45 degrees or switch the thing off for extended periods. Although I read that some heat-pump controllers have a sterilisation cycle option to heat above 60 degrees Celsius once a week to kill it.
As always, your videos are informative and inspiring. We learn so much every time. Thank you so much for sharing all you do. You are both amazing! We are always sad when your videos come to an end because we so enjoy them.
Hello, I follow you from start. I live in China at 2000 alt and have the same system installed on my roof for many years now. Of course a Chinese brand and it works amazing without any maintainance. good choice. Go on....
'...love it when a plan comes together', as they say. The best loved and most cherished utility room for a considerable radius. Congratulations, thoroughly deserved. May your bills be low for the foreseeable future.
Kylie you did an amazing job explaining air source heat pumps! I'm a mechanical engineer and have been design HVAC and heat pump system for over 15 years you did a better job explaining them than a lot of engineers :) I'm in the states and work for the National Renewable Energy Laboratory (NREL) it's a US government research laboratory. I do a lot of research in energy efficient buildings and on-site energy generation (mostly solar). You an totally power an air source heat pump system on solar, if it's all sized correctly. Just curious if you guys ever made an energy model or heating load model for your house? That it's the best way to predict if a system will be able to heat/cool on the coldest/hottest days. Anyways keep up the great work!
Hello, please check the issue regarding Legionellen in the drinking water. Once a week you should heat the water to min. 65 degree C in order to kill the Bakterien.
@@danchodancho2998 I thought I’d seen mention of that (and the anti frost) cycle in my research but must admit I’d forgotten it. 45 still probably won’t be our final temp … we want to find a temp just above comfortable shower temp (so we’re not needlessly heating water just to add cold to it)
@@MAKEDOGROW perfect! In our house we have 2 piece of Daikin Alterma 3. (460liters) In first one we heat water to 50C, in second 40C. We use thermo valves in our shower to use constant temperature and comfort - this is game changer. Btw from10C to 40Cour consumption is around 1.5kW and 4kW if we heat to 50C
Looking forward to hear about your data (electricity consumption) after your first winter ! Congratulations ! It’s always a pleasure to watch your videos !
Congrats! It's clear you guys have been pushing super hard to get to this point - I can't wait for the day you can take a shower in your new bathroom! System looks fantastic.
@@MAKEDOGROW I'd be temped to run a hot water line out a window to a temporary outdoor shower then - I imagine the solar shower has some severe limitations on shower length. Congrats again on all the progress you two are inspiring.
We are tied to ASHP because our garden is too small but here in the Netherlands we would be better with ground source. Great work guys. We see so many videos of properties in Portugal that use wood/gas and rarely do we see solar panels.
@@1Waarheidsolar panels have a lifespan and carbon footprint. It'sless than coal, fuel etc. It's going in the right direction. What do you use for power?
What an accomplishment! All your research, planning, and building came together! I am looking forward to your documenting how it works for you coming winter. As I read the comments I got the impression that you perhaps should address the final water temperature level in another video. People are concerned. People also don’t understand the difference between showering and washing yourself.
Isn’t it funny what people pick up on … I knew the showering comment would get comments 😂. We’ll definitely address the questions/concerns in another video
Since you're in Portugal you should reach an efficiency(SCOP) of 4 or 5, not only 2 as said in the video. I like the Mitsubishi Electric units a bit better(they are more efficient). Your pipes could be 32mm, I think it is 26 now. 32mm has less resistance and makes your pump more efficient! Other than these points, well done. It looks like a very clean setup. On your other comment if it's allowed to put the pipes in the wall: yes you are allowed to do that, but they need to be pipes that include thick insulation(for any expansion of the pipes).
Great job, looking forward to seeing your video on the upgrade to your solar system. I live in Northen Spain. In 2020 I installed a Victron Solar system Basic spec info is 4.8KW of panels in two arrays one 8 and one 4. A 5KVA Inverter/Charger and all the other stuff to control it. We are completely off grid. The system supports an air source heat pump hot water boiler plus a pellet burner for the under-floor heating, two fridges a freezer a dehumidifier, well pump and charges our Electric car. If you would like a more detailed overview of the full system, I am more than happy to provide it. I also keep a detailed log of the solar capture ect. I have also installed a smart home system which has enabled me to reduce the amount of electrical cabling. To date the only month of the year I struggle with is December, A backup Generator is used but only for very short periods of time during November, December, January and February.
Heat pumps can also be used for forced air systems. Not just hot water systems. For the blaymen they ARE air conditioner units. Just flowing in opposite direction. My home cools and heats with forced air heat pumps(have air handlers in attic). Our hot water is a separated all electric resistance coil unit. Another channel Wild Wonderful Offgrid run three heat pumps off grid. They live in the West Virginia mountains where it is cold. They supplement with a woods stove. He is a professional electrician so that helped them. But it is 100% possible to run them on solar. Th he have a very large array and a diesel generator as a backup as well as a large battery bank.
Pretty good instruction and understanding the heating system in Portugal...when I was there there wasn’t any house heating in any house I lived ...sooooooo.....sooooooo....very cold and humid with constant rain, I lived near the Lisboa airport where the wind was very strong also....very good learning and also good for your housing 😊🎉
Wow! Great work! So interresting and wonderful to follow your build! Thank you!! Like that you are, and that you stay, true to yourseves and your vision❤
It’s great to get workers who have pride in the work.
I must have missed it but it looks like there is no driptray and floorwaste in your utility room also i prefer to run surface mounted piping in copper which makes for a neater appearance that pex looks like spaghetti thrown on the wall old school plumber here anyway still like your videos 👍
WOW!! This is PROGRESS!! This was quite something watching these men doing the hookups. Thank you, Kylie, for explaining the system.
In 1975 we built a home in Iowa and had a heat pump installed. It worked wonderfully for the 28 years we lived in the house and the present owners are still using this system today 48 years later. They have had to replace some parts but nothing major. We moved to Arkansas in 2003 and had a heat pump installed in our new home there, and 20 years later it is still working. Cannot say enough good things about this product. Economical, reliable, comfortable winter and summer....it also did the air con in summer. I am sure there have been improvements made since our install in 1975 but all to the good I am sure. Great job!!!!!
Wow. I had no idea this technology went back that far. That is what foresight looks like. Hats off to you.
Really? A heatpump is in your fridge.. theyve been around as long as the car..
@@Deiphobuzznot technically true.
Congratulations on your new conveniences! Hopefully all your hard work brings you to an easier existence, realizing of course you have lots of projects yet to accomplish, but hopefully with less stress. So happy for you guys, onwards and upwards!
Re having exposed piping, it all looks so neat and orderly that I'd be proud to show it off! Re depending on solar panels for power, there would probably be enough heat stored in the tank to keep the house comfortable on a winter's night even if you shut off the heat pump until morning. But you won't have to, because batteries have improved to easily provide power to the compressor for many hours.
Ten years ago this system would have been risky, but solar cells, batteries and air-sourced heat pumps have all become vastly more efficient since then.
Yes, we’ve thought of this too (hence the test to see the temp drop when turned off) and during periods of grey days we’ll probably turn the unit off to preserve the power in the batteries.
We also have a backup generator but really want to avoid using it.
I am wondering why the ventilation pump has to be turned off for the day time. I have heard that in England, for example, it is customary to heat the apartment in the evening and at night for a while, and during the day the apartments are kept cold. This results mold damage inside of house.
In my country, it is customary to keep the house heating, also the ventilation pump always on, to avoid mold damage. The ventilation pump has a thermostat that keeps the desired room temperature constant. The air heat pump should be adjusted to 23 or 24 degrees in hot weather and then keep it on all the time.
Also, the humidity outside does not move inside the house when the ventilation pump is constantly on. As we all know, moisture always moves from wet to dry, which in turn worsens air quality and causes mold damage at worst.
If we switch off the device continuously, there is moist air outside and dry air inside, the moisture seeps through the structures. There will be no problems if the machine is on all the time, with a suitable coolness and the indoor air is suitably dry.
The air source heat pump is kept on even on working days, even if there is no one at home and when we go on vacation. The ventilation pump is easily damaged by being turned off and on constantly. (Executive director of Sulpu ry, the Finnish heat pump association, Jussi Hirvonen.)
@@vrvrhm8438 On a good insulated house you do not need to power off the heating. We have it all day long turned on and the consumption is quite low.Of course you are required some double/triple glazing and quite thick insulation layer for that.
I live in USA and all my pipes in the utility room are exposed. That’s how the house came it wasn’t something I chose. Who would want to have to dig the pipes out of the walls in an emergency situation when you have a leak and have to get to one of the pipes. Your pipes look very well organized and covered and labeled nicely. It’s not like you are serving dinner in there. Great job.
Congratulations! Not just for the hot water, cold water and electricity, but also for them being housed in a room with very good looking walls and floor! You guys are amazing.
Easiest way to describe a air heat pump is it's like a fridge but in reverse. In Sweden these heating systems are quite popular in (as you state) existing buildings since being relatively easy to install. If these systems work in Sweden they should be working better in Portugal.
The data of your off-grid system would be very interesting, I dont beleive that would work in Sweden considering the short daytime (sun hours) during winter months wich is the period the system is needed the most.
Final comment, Connecting the woodburner is smart, making use of the cosy fire in more ways then one.
Thanks, guys!
Expansion tank is to equalise pressure as the temperature rises and the water expands. Water expands slowly with temperature - hence the small equalisation tank 😁
Yes. Traditionally in a one story dwelling the expansion of the water is relieved by a vent pipe which goes through the ceiling and roof space and extends above the roof line. As the water expands it will move up this pipe. More commonly now the pressure is relieved by a valve and pipe that's vented under the house. As this house has no underfloor space and the roof line is so far above the hot water tank, the expansion tank is installed to accommodate the expansion of the water.
@@Brigidz In central Europe you frequently have a pressure relief valve at the cylinder that vents into a drain every time the cylinder heats up. More recently I've started seeing DHW expansion vessels like in this system (you can tell it's for the domestic hot water because it's grey, central heating ones are red, not safe for drinking water).
This vessels is divided into two halves by a membrane. One half is full of water, the other air or pure nitrogen. Water doesn't compress, so as it heats up its volume increases. Gases do compress so with half the vessel filled with a gas the water has somewhere to go. As the water volume increases the gas is compressed and once the pressure is relieved (e.g. because you open a tap somewhere) the gas expands again. Works fine until the membrane gets old and brittle but these things are cheap.
The wood burner needs a different kind of equalisation. If you've got, say, a gas burner you can simply shut off the gas as the thermostat says the water in the cylinder is hot enough. If your heat source is a wood burner you can't do that, the fire will continue to burn for a while and the heat that generates needs somewhere to go, otherwise your back boiler could explode (that does happen if such a system is incorrectly installed, I think several people were killed in such an incident in Austria a few years ago), so you need a big water tank that can take the heat. 300 l is small for that, I tried to find figures a while ago and got something like 600 l for the smallest pellet burners.
Water also contains a lot of diluted air and when heated expands so that is also i believe sorted by the expansion tank and vent valves. A boiller like a wood burner that can generate very high temperature and might be difficult to control needs the expansion tank. While a system like a heatpump that will keep the water temperature and pressure under tight control, can do without it.
Should the wood burner not be open vented separately?
I live in Sweden and have an air/air heat pump to heat the 112 sq. m. house(no hot water) and it can still keep the inside temperature at 20 C when it is -20 outside.
Congratulations guys! You deserve all that the system can deliver, considering all the hard work you put in. 👏👏👏
Like every other subscriber to you, I share your excitement! It is a little odd that I find it fantastic and wonderful that a house in Portugal, belonging to people I don't REALLY know, has got an air source heat pump, water and electricity. But I am delighted.
On the otherhand we know you, we know how hard you have worked to get this far, we appreciate your well made videos showing the mistakes as well as the successes. It is odd. I might meet you in an airport one day and see a couple I know as 'friends' with very similar views to me but you barely know I exist. I wouldn't dream of writing similar to Taylor Swift or David Attenborough, but isn't it broadly similar? Do you have bodyguards when you go to the supermarket, or send minions? (tongue in cheek)
(Small aside, I genuinely bumped in to Angelina Jolie and Brad Pitt in my local supermarket some years ago, shopping for themselves without 'security')
First, congratulations on this monumental achievement and quality of life advancement! Second, evidently a lot of the rap on heat pumps is fossil fuel industry disinformation. The NYTimes and the Washington Post have both done extensive coverage on heat pumps during the past several months, for anyone interested. In particular, there’s a WaPo article from Feb. 7, 2023, about how heat pumps are working great even in chilly Maine, and all the oil industry panicky pushback. And there’s an NYT article from Feb. 22, 2023, about how well heat pumps handle the cold (tl;dr, they do have to work harder in cold weather, but they’re still more efficient than fossil fuel-run furnaces and boilers). Third, they can be used to cool homes too, which will probably be of increasing interest to everyone.
I think the same is the case in the UK, bad mouthing from the gas industry (most central heating is via gas boilers).
Hopefully over time as more positive case studies energy the general public will become better informed.
Our system can also run the radiant system in cooling mode. I’ll be interested to test this and see if there’s any resultant condensation on the floor
Pls keep in mind a few variables need to be in your favour to make best use of such system. For instance low cost electricity, the ability to install on your property (space, pipes) and location. It's much more challenging to upgrade eg apartment buildings, buildings with poor infrastructure, areas with high electricity cost etc.
I'm not a fossilist 😂 i own a solar powered property in the Algarve with electric, floor heating battery storage and electrical vehicles.
Well done guys, very impressed with what you guys are doing👏👏👏👏
Careful with Legionnaires' disease if your water isn't hot enough. But it's great that you guys have hot water now 😊
Looks great!
I can support your intuition that your air-water heat-pump together with the solar PV modules, provided you have enough battery capacity, will make you through the winter.
We live in south Germany, near the Alps and, on average, we have some 10-12 weeks with temperatures below zero, and from those we have 2-3 weeks where the outside temperature is below -10ºC 24/24h. We have also underfloor heating, and an air-water heat-pump with a 750 liter tank. The heat-pump struggles on those "below -10ºC" days, where the efficiency really drops, mostly due to the fact that the cycle must reverse several times per day to unfreeze the outdoor unit. It is not perfect, but 10 years ago the technology was not as evolved as today. On our case a geothermal heat-pump would be the ideal choice, but the original builder/owner did not considered it at the time of the construction works...
We also have a 18kWp solar array with a total of 18kWh battery capacity, which provides us with 85% autonomy/year (we just need some external sourcing from the public network between November and March, mostly when the roof is covered with snow). So, with the portuguese climate and proper sizing of the solar power system, you will for sure be fine, even without the wood burner.
We are also planing our move back to Portugal in a few years time, and I am still somewhat hesitant between an air-water and a geothermal heat-pump. So I'm eager to see the data you will be collecting from your set-up.
Keep on the good work!
"utility room" a.k.a. "mission control" - fantastic job!
You both must be over the moon happy with this milestone!!
You both are creating a home masterpiece. Enjoyable to watch your progress from time to time.
Awesome accomplishment friends! Love seeing your progress ! You certainly have worked so very hard! I am glad you can get into your house!
You may want to consider solar back up, as you age wood heating is a lot of work! A little of both?!
Anyway, take a good holiday so you stay healthy!👏👍😁Your bodies deserve it! The house will be there in 3 days😜👍😁👏❤️
I really love the detail that you go into with your building projects! You work so well together!
So take good care of yourselves! You are doing a lot!
I just moved into a small home in Maine! I do oil paintings and after caring for my husband who had Alzheimer’s, I am now able to enjoy life again! Rich made 90👍👏 and we got through a very stressful time for 6 years with his passing at 90! So health is important! I see you wear breathing protection! 👏
Keep safe and healthy and hopefully , you can start to enjoy living in your Portuguese home! It ‘s certainly going to look lovely with your care!
Hopefully your garden will feed you through the years to come!👏👍🍋😁❤️👏
I live in Switzerland and built a wooden house with passive energy level. I do have an air based heat pump and it works perfectly. The systems works because any temperature over 0° Fahrenheit (helps to understand better) is physically "warmth" or "energy". So also when here in winter there are - 20° Celsius, it does its work. Only problem I encounter is that whenever the temperature drops quickly, the pump needs a bit of time to heat up. So I have a wood stove and a fire place that I use in those cases to warm up the house for the max. 1 day until the heat pump is again on full mode. Congrats to your milestone!!!
ASHP will be fine off grid. Anyone saying otherwise it wrong.
You’ve got underfloor and good insulation, solar and some battery storage. It will work fine. You won’t even need to use your back boiler (although it will be cozy to have the fire going)
System looks amazing. Looks like you’ve covered all angles.
I look forward to seeing update videos on the performance 👍🏻 congratulations
The only thing we’re a little concerned with is the number of grey days that won’t produce much power. Last winter (which was the worst for this are in a very long time), there were 40 days when we weren’t producing any power and had to use a generator. We’ve beefed up both panels and batteries, but it’s always good to have multiple backups 😀
Plus, who doesn’t love sipping wine by a fire 🤣
As long as you are above 0K = -273°C = -460°F, molecules are moving.
Some how I don’t think they have to worry about minus temps
@@bridgwll He's just showing off how smart he is. I have to admit I didn't know when molecules stopped moving ...that's impressive.
@@kindlydude lol.
Here in Portugal we call the utility room an "engine room"😁 nice work!
Congratulations on your install!!! 👍👏👏👏 I hope it makes life more comfortable for you. 🥰🎶❤️
Thank god for that, its been getting cold recently.
😂🤣😂
@@MAKEDOGROW Glad I made you laugh. Frankly, this is the best time to install a heating system, and your installation so far looks excellent! We have a log boiler and radiators waiting on the plumbers leisure. I hope we can get it all completed by winter. Ours will be log fired with vacuum tube solar for summer hot water.
@@SailingCartagena yep, this is one of the reasons we got it done now … virtually nothing happens in July/Aug and we didn’t want to risk having it installed in the run up to winter
I learn so much from watching you and look forward to your solar videos. It’s a huge leap in your progress and so well planned. Bravo!
€12,000 is a good price for all the equipment and installation. Yes, the heat pumps do run off solar alone, the converters are the keys.
The heat pump looks very similar to the ones in Canada that heat a 1,000 sq. m home with the proper windows, doors, and insulation.
Excellent job those guys did, tidy, easy to access.
Enjoy! You both deserve it. 💦
@MAKDOGROW the heat pumps are being delivered, used in a lot of places now during renovation.
They work well as far North as Edmonton, Alberta which can get to -35. The fossil fuel industries have tried to keep people away from both solar, mini turbines and heat pumps. 😡 The number of EV trucks, cars is getting to be far less noticable because there are now so many on the roads, wonderfully quiet.
Canadian Permaculture Legacy has a video showing how much money is saved by driving an older Tesla, something like $7,000/year!
The room is a mechanical room and you should be proud of yr work & yr vendors, why go covering the craftsmanship, the neatness and well laid design given yr constrains, its a wonderful marvel you have created.
I say don’t cover the pipes etc …. SHOW what you have done, stand tall n happy 😊🎉
Progress, progress, progress.....always amazed. Todd, Debbie & Madyson, Tulsa Oklahoma USA
First time I've heard of, much less seen, an air supplied heat condenser. I had a friend who ran an outfitter business up in Canada who installed (by himself, as I gather) an underground heat collector/condenser system and it kept them warm and snug at -59 F during the winter with no need to run a wood stove to augment it. So I know that worked in extreme conditions and am looking forward to see how your system works in a moderate climate. Clear explanations are priceless and you both hit the mark spot on. Thanks---and I'm looking forward to your next episode with whatever you have on the hob.
Air source heat pumps are being used a lot throughout Europe and are even widely-known here in the UK where there is a government not well-disposed to renewable technologies. There's certainly a lot of garbage being pushed about them in our media.
I think the most easily understood concept of air source heat pump was a domestic fridge. The fridge maintains a colder air temperature than ambient air and the compressor etc pumps the energy out as heat through the radiator at the rear as heat. Effectively identical as your underfloor heating pipes. You'll find that the air source heat pump will work over a wide range of temperatures however as the temperature drops the efficiency will change. So,whilst you'll still have heating You'll not get the suggested 3:1 ratio
Yes, it's like a fridge without a door built into the wall, with the opening outside.
That's fantastic and a very big step in making your home livable! I can foresee comfort in your future!
The expansion tank is for keeping pressure differential stable while the water heats up. This one is just for the expansion of water in the boiler. You really need a bigger seperate expansion tank for the water in the underfloor heating because when the temperature of the water is low and the heat pump starts the pressure drops and the flow rate decrease until it gets the setup temperature. This slows the heat transfer. It is also usefull to use a different tank as a buffer tank from the unit to the underfloor heating so the compressor of the heat pump doesn't open and close many times. An engineer can take a look on this.
Huge game changer. You'll be indoors, warm and wet this winter. 🎉congratulations 🎊
Be aware that 45 degrees is in the ideal range for legeonella to multiply. If you are not planning to use too much water it will exacerbate the risk. The water must be heated above 50 degrees to kill the bacteria. Best wishes
A friend of mine had a air sourced heat pump for his outdoor swimming pool. He put a poly shelter over it so that it could be used all year round, the amount of heat within that cover seemed extreme so we installed ducting so that the heat pump could recycle the warm air to heat the water. It worked a treat.
We run a similar set-up here in the U.K. - solar PV powering our Daikin ASHP for UFH and hot water. Our climate is considerably colder but we are still getting an annual average COP of 3.
Nice! I doubt we can achieve a 3 yet (with leaky doors/windows, no insulation upstairs, etc) but it will be super interesting to watch this winter and see things improve over the years as we get closer to a finished building
Such a wonderful couple. Pure class. Cheers🍺🍺
We installed an air sourced heat pump 20 years ago but unfortunately at that time time there were numerous compressor issues, so that eventually after some years of repair and replacements, which the company were happy to do, we switched to solar generated electricity with a standard tank. We are in Australia and the compressors were only produced on the west coast and had to be transported all the way to the east coast. When it did work it was great. So glad the technology has caught up with the vision. We now have a new technology installed within the tank system that stores the unused solar power for times when sunlight isn’t available (that would be at night 😁).
Congratulations, moving forward and setting new frontiers in technology and management. More challenges to come. A’bientot from 🇫🇷👍🍷🇬🇧🇪🇺😍
Brilliant, you must be extreamly chuffed with what you have done. It all looks great.
Really looking forward to Kylie silencing the naysayers with actual data on the viability of running heat pumps like this from solar. Nice video.
I like the exposed piping and wiring it's purposeful. Especially in this room
It is always such a pleasure to give (and to hear) a genuine positive review of work that has been done.
Love the idea of the wall mount. It wasn’t suggested when we installed our split system. One suggestion, take pictures of each area, print them off and write very detailed of what pipes and tube go where and how they are run. Your memory now is wonderful, but a few projects down the line our memories get a bit blurred. This saved us a big headache when I decide to run the water to the laundry room a bit different…didn’t do it as it won’t have cut off the water to the powder room!
Great job on the prep work and the heat pump install. I'm looking forward to the video on the ventilation installation. I know the brand of ductwork you're using. 5 tips here. 1. Don't save on the number of ducts. If the duct identifier says AE34, you should not use it for more than 34m³/h per duct. AE48 is 48m³/h and so on. 2. Don't make the ducts too long and avoid unnecessary bends. A rule of thumb is: the outer diameter in cm is the maximum length in meters if you use it for the maximum flow rate (tip 1). 3. Avoid any bends really close to the collectors. If there is residual tension on the duct going into the collector they could leak. 4. Look at the instructions in the box of the collector. These are great. 5. The manufacturer has superb graphs on the combination duct size, length, and pressure drop. Use those to make a detailed pressure drop calculation based on your ductwork layout plan.
Amazing quality of installation seems a bit of an understatement!
Wish I could get guys that do that kind of clean work here in the US. Small tip - pass-throughs in exterior walls and foam insulation around piping attract mice, so stuffing in a layer of copper wool on the outside prevents mice from chewing and squeezing their way in.
I'm impressed guys, so clever, savings will mount up and it'll pay for itself over the next few years.
This is big step for you so hopefully next winter will be more warmth for you😊
OMG they were so young too. Happy for you both!
Wow, you both won’t know what to do with all your new stuff, you both work so very hard, we look forward to your videos all the time, so many changes and the difference, it’s really coming along, your going to have a fantastic home at the end. How’s the chickens doing? Haven’t seen them for while, and how many kittens did you keeps ? 😅
Bravo you guy's, you've come a long way working so hard. Much love from Oklahoma USA Jackie 🇺🇸 💖
Love the way you have curved the area around that small window. I have a 1930s house in Melbourne Australia which is double brick and all the windows have that curving or rounded edge which softens the light coming in to the house.
One tip if i may ,attach a pipe or a hose to the pressure release valve to direct the water outside or in to a bucket because the last thing that you want is for something to go wrong and the pressure to rise to the point that the valve opens ( and instead of saving your system )dumping water all over your heat pump potentially creating a short ask me how i know
Yep, once we have the waste pipe installed we’ll run into that. We also need to add a pressure relief valve to the ufh manifold and run a pipe for that too (we weren’t aware we needed that until the guys did the install)
Heat pumps still work just fine below zero. We use them in Japan year-round, and many other countries are similar. The efficiency issue is mostly caused by the defrost cycle that's needed in freezing temperatures, but still it's more efficient than electric resistance heating.
I think you have an angel watching over you….min 9:38 when you’re explaining about the “misconception of the heat” - a wisp of light floats from above your left shoulder / right corner of window…and it makes sense when talking about “energy”. Just something Interesting. Love your channel!
Congratulation for your BIG day...achievement. It is great to finish a project that takes soo long to complete.👏👏👏 Good job!
Looks like a tidy job
First of all, you both look less stressed in this video. I have Daikin and I live in Italy. in the mountains. It snows maybe one day a year. So not too cold. My electric bill is not outrageous and the heat and AC work very quickly and are efficient. I have hot water on demand. I have replaced all my windows and doors with double insulated and my house is cozy. I have a ground floor cantina which I heat with a small pellet stove. I do not have solar, sadly. But most of our village is run on Wind power. I am so happy for you both to have your heating, water and flushing toilets. Bravo to you both.
Omg!!!!!! Life changing !!! Gread research, incredible result and great minds behind!!!
a big step accomplished. sounds worth every penny!!
I live in the U.S.A. and have a forced air heat pump for heating and air conditioning. Winters average -6 C and very hot summers 32 to 37 C or more on occasion and I am very happy with my heat pump.
Nice touch from the installers to label everything in English for you.
Congratulations! We have the same system. So solar and Air source heat pump. We have a Panasonic Aquarea. It's just amazing. No underfloor heating just conventional iron radiators. We have a large Stone Bastide and adjoining gite for anyone that doubts you can put in old buildings! Insulation is crucial. Its currently 29 degrees outside (I am in the south of france) and the house is a consistent 20 all . year round. We have a wood burner to chug up the direct heat in the winter. You will find that you will have more hot water than you can even imagine. We can have a houseful and gite full and everyone can have showers. we have two dishwashers; two washing machines and we have never run out. We find it runs really well in the winter and we get down to minus 10- 15 in the winter. Panasonic have a model called T cap which functions normally in extreme cold weather.
Legionella may be a risk though if you keep it at 45 degrees or switch the thing off for extended periods. Although I read that some heat-pump controllers have a sterilisation cycle option to heat above 60 degrees Celsius once a week to kill it.
Yes, the unit has one of those cycles. And, this temp was only for testing
As always, your videos are informative and inspiring. We learn so much every time. Thank you so much for sharing all you do. You are both amazing!
We are always sad when your videos come to an end because we so enjoy them.
Hello, I follow you from start. I live in China at 2000 alt and have the same system installed on my roof for many years now. Of course a Chinese brand and it works amazing without any maintainance. good choice. Go on....
Wonderful explanation of how this system works in winter temperatures. Thank you
So happy for your accomplishments such a load off your shoulders. Great days ahead
'...love it when a plan comes together', as they say. The best loved and most cherished utility room for a considerable radius. Congratulations, thoroughly deserved. May your bills be low for the foreseeable future.
Kylie you did an amazing job explaining air source heat pumps! I'm a mechanical engineer and have been design HVAC and heat pump system for over 15 years you did a better job explaining them than a lot of engineers :) I'm in the states and work for the National Renewable Energy Laboratory (NREL) it's a US government research laboratory. I do a lot of research in energy efficient buildings and on-site energy generation (mostly solar). You an totally power an air source heat pump system on solar, if it's all sized correctly. Just curious if you guys ever made an energy model or heating load model for your house? That it's the best way to predict if a system will be able to heat/cool on the coldest/hottest days. Anyways keep up the great work!
Kiley, that was clearly explained, thank you! Good luck with your new system! Laura ❤
Hello, please check the issue regarding Legionellen in the drinking water. Once a week you should heat the water to min. 65 degree C in order to kill the Bakterien.
The current temp is not the final temp .. since we’re not using the system just yet
@@MAKEDOGROW don't wary, Daikin have weekly probram about this. Btw if you use every day full tank then you don't need this program
@@danchodancho2998 I thought I’d seen mention of that (and the anti frost) cycle in my research but must admit I’d forgotten it.
45 still probably won’t be our final temp … we want to find a temp just above comfortable shower temp (so we’re not needlessly heating water just to add cold to it)
@@MAKEDOGROW perfect! In our house we have 2 piece of Daikin Alterma 3. (460liters) In first one we heat water to 50C, in second 40C. We use thermo valves in our shower to use constant temperature and comfort - this is game changer. Btw from10C to 40Cour consumption is around 1.5kW and 4kW if we heat to 50C
excellent explanation by both of you, especially Kylie explaining all the steps in plain speaking terms kudos to the pair of you :) :)
Looking forward to hear about your data (electricity consumption) after your first winter !
Congratulations ! It’s always a pleasure to watch your videos !
YeeeHawww! Finally a really snazzy and effective completion of a long hard project. Congratulations and enjoy :)
Congrats! It's clear you guys have been pushing super hard to get to this point - I can't wait for the day you can take a shower in your new bathroom! System looks fantastic.
Yeah, us too!! 😀
We’ll have to settle for a flushing loo this year, don’t think we’ll get to the upstairs bathroom until next year
@@MAKEDOGROW I'd be temped to run a hot water line out a window to a temporary outdoor shower then - I imagine the solar shower has some severe limitations on shower length. Congrats again on all the progress you two are inspiring.
Fantastic idea having your heat pump system set up to take multiple sources, especially tying in a fire and back boiler.
Always look forward to your videos. Seeing the results of your research, careful planning and hard labor come to fruition must feel wonderful.
*Wow that looks great... YAY finally you have heating and hot water inside. I guess you will be moving in full time soon and out of the tent.*
Great job! You are ready for anything, have alternatives Love that.
Great explanation on how it works and why you selected it. You make my engineer heart happy!
We are tied to ASHP because our garden is too small but here in the Netherlands we would be better with ground source. Great work guys. We see so many videos of properties in Portugal that use wood/gas and rarely do we see solar panels.

Fabulous! Another stage completed. Well done guys!
Really neat job. I feel relieved for you that the heating is in. I suffered for you guys last winter.
What an accomplishment! All your research, planning, and building came together! I am looking forward to your documenting how it works for you coming winter.
As I read the comments I got the impression that you perhaps should address the final water temperature level in another video. People are concerned. People also don’t understand the difference between showering and washing yourself.
Isn’t it funny what people pick up on … I knew the showering comment would get comments 😂.
We’ll definitely address the questions/concerns in another video
It’s amazing just how much work goes into installation of said equipment, not to mention all the prep work you guys did prior.
Since you're in Portugal you should reach an efficiency(SCOP) of 4 or 5, not only 2 as said in the video. I like the Mitsubishi Electric units a bit better(they are more efficient). Your pipes could be 32mm, I think it is 26 now. 32mm has less resistance and makes your pump more efficient! Other than these points, well done. It looks like a very clean setup.
On your other comment if it's allowed to put the pipes in the wall: yes you are allowed to do that, but they need to be pipes that include thick insulation(for any expansion of the pipes).
Golly, that was complex, it did my head in.
Great job, looking forward to seeing your video on the upgrade to your solar system. I live in Northen Spain. In 2020 I installed a Victron Solar system Basic spec info is 4.8KW of panels in two arrays one 8 and one 4. A 5KVA Inverter/Charger and all the other stuff to control it. We are completely off grid. The system supports an air source heat pump hot water boiler plus a pellet burner for the under-floor heating, two fridges a freezer a dehumidifier, well pump and charges our Electric car. If you would like a more detailed overview of the full system, I am more than happy to provide it. I also keep a detailed log of the solar capture ect. I have also installed a smart home system which has enabled me to reduce the amount of electrical cabling. To date the only month of the year I struggle with is December, A backup Generator is used but only for very short periods of time during November, December, January and February.
I'm very glad it went well for you!
Lovely to see good workmanship.
Excellent you two, absolutely love following your progress. & mainly love your humor & attitude between the 2 of you .Max
Heat pumps can also be used for forced air systems. Not just hot water systems. For the blaymen they ARE air conditioner units. Just flowing in opposite direction.
My home cools and heats with forced air heat pumps(have air handlers in attic). Our hot water is a separated all electric resistance coil unit.
Another channel Wild Wonderful Offgrid run three heat pumps off grid. They live in the West Virginia mountains where it is cold. They supplement with a woods stove. He is a professional electrician so that helped them. But it is 100% possible to run them on solar. Th he have a very large array and a diesel generator as a backup as well as a large battery bank.
We have ground source heating in Orkney. Xx
Beautifully elegant system!!!
Pretty good instruction and understanding the heating system in Portugal...when I was there there wasn’t any house heating in any house I lived ...sooooooo.....sooooooo....very cold and humid with constant rain, I lived near the Lisboa airport where the wind was very strong also....very good learning and also good for your housing 😊🎉
Wow! Great work! So interresting and wonderful to follow your build! Thank you!! Like that you are, and that you stay, true to yourseves and your vision❤
We had the same system installed in France for our underfloor heating and hot water. We also had a water softener installed.
