The Case for Wood Stoves in Rural Homes

Wood stoves face criticism for their carbon emissions. That makes sense in cities, where CO2 levels are higher. But out in rural, forested areas? Seems unfair. Wood is a renewable biomass. Burning it does release some CO2, but it can be sustainable if we harvest properly and avoid clear-cutting. Plus, modern wood stoves produce less smoke and can improve air quality. Of course, safety is crucia...

Bridging the Gap: 4 Benefits to Building Attached Greenhouses
Many ancient man made structures are good examples of your project. By natural means made of simple material that is available in nature and prepared in simple methods and that blends with nature without disturbing ecological and environment. Those who get irritated should try understanding. That will rather be an intellectual ointment!
What if you don't make any clerestory windows? I am going to make something in subtropical India
Are you ai generated? You're beautiful
All new buildings should be designed with large roof overhangs. The large overhang provides beauty and protection from the sun, rain and wind. Protection of the doors, windows and siding make for a more durable and comfortable home.
New homes should come with solar panels, a rain water collection system and an electric vehicle charger in the garage.
All homes should be built to accommodate the elderly and disabled. This will be better for everyone. Large wide doorways and hallways make using a cane, walker or wheel chair much easier. Bathrooms or wet rooms need to have flat floors and no shower hump or pan. A flat floor allows for easy access and drains need to provided. Easy to use lever door and faucet handles are easier for the elderly to grip and open. Main floors should include a master bedroom, restroom, shower, laundry and wide walk in closet with few steps to enter. Homes should be designed with aging in place in mind.
These are all free. It's incredible how many modern-day designers and builders do not consider passive solar design and build principles. Thank you for spreading the word.
In our region the air is too hot outside. So I think passive cooling rolls can't work here. Am l right?
This is the first video I come across that explain the dynamics of passive cooling of a structure. Thank you! Many videos address the A/C systems and “close envelope” of the structure, but the content of your video is very interesting!
I like your content, but I like to point at the sun having the highest power at noon (the sun's highest point) which in the northern hemisphere is south. When hitting glas, the light is "converted" to heat. Preventing the most powerful light to fall through glass will have the highest impact. The highest temperatures though are in late afternoon as it takes time for everything to heat up. When you are not in a region with heavy or frequent rain, it makes more sense to have outside window blinds like the ones you see in Spain or Italy than any kind of roof. You have a light and bright room when you want it (winter) and can keep the sun outside when you need to.
Well done, girl. 🎉This is exactly what we need to resort to - nature. Nature has treasures of comfort and solutions to our excesses. All we need is wake up to it. Let me congratulate you for showcasing a noble novelty we have distanced from over the years in search of comfort and returning to it for the same. Christina you are marketting gifts of nature and I love the very idea. I love countryside living and have been enjoying many of the nature's gifts most of my life. I am planning to build a granpa house using gifts of nature, no electric lighting during day. Cooling without ac, potable water from humid air, a slide with each stair, worm holes between floors for kid adventure, a diy family workshop. A rugged but safe lift between floors (when my knees back out on me)😂, and so on it goes. Imagination, imagination, imagination!!! Christina, I am 70. Will you help me design my house. You will be my guest in Pakistan when complete and I will take you around to Gilgit, Kashmir & to stunning beauty of further north. So, what do you say, nature lover? I am a mechanical engineer with hydropower as lifetime profession. Your presentation was substantial with simple science, I have subscribed your channel to remain in touch.
hwo did they do it? magic.
This is really good. I'm going to be building a house in the philippines, could you please do a video on how to reduce energy consumption in a hot and humid climate? Thank you.
Thanks! That is a good suggestion! Humidity can certainly get tricky, so will have to
Usually people think insulation is for cold climat only. But it actually works in hot climate, too. It reduces heat (or cool) "travel" in both directions. You would need less ernergy to keep a room or building cool. However, solar panels may reduce your costs on the mid-term run, too. After 20 years they usually still have 80% of their initial performance.
@leonlowenstadter9223 to anyone who knows this better than I do, my question is this. If we're in the Philippines for the ambient temperature during the summer is 90, and I'm comfortable with my house at 80 with ceiling fans, that's only 10° difference. If I'm in the north where it's 0 outside, and I want my house at 68°, that's 68° that I have to keep out. With only a 10° difference between outside and inside temperature, the insulation requirements have to be a lot different. I'm wondering if I should spend money on solar panels and air conditioning versus insulating the walls and ceiling and getting double or triple pane glass?
@johnb5478 Honestly, I am not an expert but I taught myself a lot about it. However, the insulation would make most sense on walls to the south so that less heat passes the wall. Insulation on the ceiling or the floor are more for cold climates as you like to keep the heat from exiting upwards or the cold "draining" heat from below the building. Replacing the windows is far more expensive than insulation, so this is usually a bit further down the road. However, insulation needs to be thought in combination with your high humidity (mold). On the other hand, compared to solar panels and A/C it's no maintenance. As you probably have many sunny days A/C with solar panels probably makes most sense as A/C reduces humidity, too.
@leonlowenstadter9223 thank you for the reply. I had considered getting a whole house dehumidifier, but I don't know why I wasn't remembering that AC also removes humidity. I appreciate you reminding me of that and we will stick as much money as we can into keeping the sun off the walls and windows and get some panels and mini splits where we need them. Thanks again.
Great! ❤🎉 now we need a video on passive heating
Thanks! Totally, on it! Also, coming out with a passive solar course soon! stay tuned :)
1:10 appreciate the disclaimer. Hot and humid is difficult. Stay slim, do, eat, and wear little?
hahaha! yes!! I am working with a mechanical designer on some passive solutions for this but still knocking our heads for that one!!
suggestions: camera position is too low, move it up and stop moving your chin up. Plus it might be a good idea to do some vocal warm ups prior, you're voice is a bit too nasal sounding.
Thanks for the feedback! I'll work on the camera angles and voice work for the next one!
Good presentation!
Thanks! Glad you enjoyed it!
Nevermind the naysayers and those who seem to think their criticism is warranted. This video was very well put together, and diagrams and design sketches usually give much more detail than actual pictures of existing structure. If your viewers call for real life examples, you can always put together a video or series of videos featuring that, but those examples don't HAVE to be included in an instructional video like this. As for criticism regarding your filming and framing, let your video editor worry about that, if you have one, and if you do it yourself, don't take just random advice from random internet strangers. Your video editing looks great.
good luck editing having the camera position too low
Blindly criticizing someone makes you a jerk, but blatantly lying and brushing off clear faults is equally bad. Pretending everything is perfect helps no one, least of all the creator, who might genuinely want to improve. Constructive feedback, even when critical, is far more valuable than empty praise. Dismissing valid observations as 'random advice from strangers' not only disrespects those who take time to offer input but also undermines the creator's growth. Encouragement is great, but it should never come at the expense of honesty and meaningful improvement.
Thanks for the encouraging words - I appreciate your support!
One of the largest problems is the heat transfer through the exterior wall studs. I have built a small cottage. What I did was to have a second course of 2X4 studs. The top and bottom plates are 2X6. The first set of studs are structural and hold up the outside sub-siding and siding. The second set are also 16" on center, but set two inches 'in' and staggered in the center of the bays of the other set of studs. This second set of studs holds the insulation and the drywall. Now, no stud touches both the drywall and the sub-siding/siding; there is no heat transfer through the wall. Another gain is quiet: my cottage, while not sound-proof, is much quieter than without this stud scheme. And it is not expensive.
Thank you. 😊
Glad this video was helpful!
I feel you should have at least discussed fiberglass and rockwool
good point! I could elaborate on other options in another video
Visit Kerala India to see some amazing work on climate ready homes
Can you make videos on that?
Thanks for the tip! I'll have to check it out!
On climate ready homes? or on Kerala India?
This is the best summary I've heard yet. Thanks!
Aw thanks!!
You are showing design not real picture it could be fantastic if you could show real picture how could cool
Exactly!!!!!👍🏾👍🏾
Thanks for the feedback! I'm planning on creating a video with more real-world examples in the future, stay tuned!
You make fantastic TH-cam videos keep it up!!!
Thank you! I appreciate the encouragement!
I'm designing for a tight house but also for passive ventilation with my fans, window types and placements. For those nice sping and fall days where I don't need to run my hvac and dehum.
Very smart!
A fundamental part of marketing is "education" or information.
Absolutely! Education is key!
What are your thoughts on rock wool for insulation? Great videos! (Just came across your channel & binging through your library! 😂)
Thanks for following along! I actually think Rockwool is great for certain applications, especially roofs. I regret including it in this video! It does require a bit of processing but is generally a pretty low carbon footprint. Its great on roofs because of its high R value, waterproof and fireproof properties. Its a great when used as exterior insulation. Hope that helps!
@christinaransbury Thank you! Yes, I was thinking it would be great for the exterior envelope. 👍
Put the camera 6" higher, remove glasses to remove glare. Use animation to show low and high pressure zones, easy with ai
Is this supposed to be criticism or unsolicited constructive criticism?
Thanks for the feedback. I am generally new to TH-cam!
Love this content.
great stuff
I'm totally into all this! I live by an experimental house from back in the 70's that used a pool of water on the roof!
Was it still? Sounds like a mosquito breeding factory
Yes! That is another method that can also be used for passive heating and storing heat since water is such a great thermal battery. Im hesitant to put water on roofs in my projects (just from a water proofing standpoint). How is it currently performing after all these years?
Hahaha! Im assuming it was enclosed.
Cob and straw bale
Awesome.
thanks Christina
Cool !
You explained passive house really well! Thanks for that!
Glad it was helpful!
Excellent video and explanation!! one thing i would like to push back on the the amount of glazing. 7-11% is not at all how one should calculate how many windows. it should be how long the sun is hitting the inside of the house and how much thermal mass. and how cold it is outside. R value of window. also if it gets to hot in the house can always open windows/vents to cool it. I personally want much more than 7-11%!! but i suppose you could argue if you increase the windows you lower the insulating value to keep the heat in, but it dose not matter because the heat gets stored in the thermal mass!
Hey! Those are all important considerations. It is certainly a rule of thumb I am sharing. The density and type of thermal mass, R values of windows and walls, plus climate considerations are also important. All of the ~100% passive heated and cooled buildings historically have actually been closer to 5% and are way more efficient than passive house standards. I am currently working with a mechanical engineer on a calculator for this. Running an energy model in a program like WUFI Plus is helpful in understanding the thermal mass properties and the climate. However, we have statistics that show that 5% is sufficient for most 99% naturally conditioned homes.
What about pfas in any if these materials?
Thats a great question! I'll have to look into that a little closer. From what I understand PFAs are more prevalent in coatings and adhesives, so would mostly be a concern for the air barriers and not the insulation. I think there are some water based air barrier sealants out there that may be a good option, like Prosoco. I will look into these a little further! Learning more and more every day!
really excellent graphics. I love the combination of the primal elements tied to the climates. Also I appreciated the unique alternative solutions presented. Really clear.
Hey! Thanks so much for the feedback! Im glad these videos are proving useful!!
I am planning to build a house in Indonesia, under Passive House Principle, the house should be airtight, however, in hot and humid regions, we need as much cross ventilation, so how should we best apply? And how do we assess wind direction on the site? Thanks
Hey! I am about to put out a video on Passive Cooling! Stay tuned!!
@@christinaransbury Thank you!
Need a better microphone. Background noise is distracting. Thank you for sharing your knowledge. Love❤
Thanks for the feedback! Its a bummer I can't go back and change these once they are uploaded. Ive upgraded in more recent videos :) Thanks for the encouragement!
I love woodstoves! Had one in my yurt, then lived in a cabin in a community that had one. Nothing warms the soul like a woodstove. Plus, some of these newer double-burner stoves on the market have incredibly low emissions
Exactly!
I'm about to start building my own home and I don't have enough money to do it. . I'll be doing most of the work myself . I'm going to use a system called X-bracket by insofast . It seem like the fast and cheap way to get 4 inches of spray foam insulation on the outside of the house in an inexpensive way .Its new but they have lots of videos on youtube .Just wondered what you would think of them ? And also what would be the less expensive but healthy way to use their system ? I'm in Asheville NC .Heres a link or just look them up . th-cam.com/video/RcY11UV7x8U/w-d-xo.html. I would love to hear your thoughts on them. And yes I know Im crazy for building without enough money. But sometime you have to do what you have to do and life doesn't give you any other way out. I trust that I'm always in the right place at the right time.
well done video!!
Thanks for watching!
The real ecology issue is we're building structures with wood and have several industries developed around that. It's crazy considering the superior alternatives used throughout the world.
I agree! A lot of mass walls out there that are more efficient and less risky! Primarily and issue in North America
measuring carbon footprint is non-sense political tools.
there are additives to these now the stop fire, mold, etc... not a fan but it works much better than the alternatives. Home designs in the US make it easier to install and do it well. The moisture mitigation caused by air leakage is far superior with spray foam. By many definitions of eco-friendly and environmentally-conscious it works because of the short-term benefits such as no drafts, immediate savings on heating, and long-term savings in money from heating and not needing to replace wood and walls due to air leakage causing rot.
Totally understand your point from a building science perspective and with conventional framed wall systems. Just exploring alternatives here for those who want a more naturally based home from a materials perspective.

Good video. Just one correction though...heat pumps are for heating/cooling and are not the same as heat recovery ventilation systems (HRVS). Heat pumps aren't necessarily required for passive houses
Thanks for the reminder! Yes, I have since learned this since I posted this video a year ago. I'll have to repost this one with a few updates soon!
