Can you heat your house with no energy during winter? Heres a real world performance example. 25 degrees outside and 65 degrees inside....no electricity... @svenh 👀 what do ya think 😁 https://youtu.be/WRYO0spgonU?si=1eQ8qBSTXRCG-Rsl

Yes 100% possible. My future design aims to be fully passive solar. In my current dwelling I am during the day, and built a walker stove (Tiny rocket mass cook stove) for the night. Use about 1 cord of wood a year. I do plan to include a similar stove in the future design for those 1-2 weeks a year where the overcast is long enough in the winter. It's all about 3 things. 1. Thermal Mass 2. A way to charge that mass with the right window to mass ration and exposure. 3. Insulation Personally my (currently in redesign) future dwelling will likely be largely underground in a hillside to tap into earth stable temperatures. This alone should make a huge difference.

Passive geothermal is the way! I've been researching ground-air-heat-transfer designs for greenhouses to create passive zone boosting. After I test it out for a greenhouse I'm curious to see if I think it has application for a home design.

Earthships do that usually pretty simple by running culvert or oter tubes out back through the berm. I am toying with sand battery ideas to store excess electricity once my batteries are full. Industrial versions come a long way, but should be simple enough to build myself. Hyper insulated box of sand underground with heating elements... done. I also like decouple ground heat pumps (diy or otherwise) to avoid possible radon and moisture issues in earth tubes. Can be as simple as 1" tubing with glycol attached to a radiator, or hooked up to a heat pump for more efficiency. And before someone says it... yes i'd love to use excess electricity to mine btc and use the heat. But the miners are just too expensive for my personal project. Maybe we could play with that for Coyote Commons some time.

Good considerations! Had similar thoughts re: decoupling. Sand battery seems fun!
