By placing the fire and chimney on opposite sides of the house and constructing a tunnel between them, heat is pulled through the tunnel, heating the floors and helping distribute heat more evenly.
Note: caused a significant number of house fires and carbon monoxide poisoning.
I figured there were some issues like that, I think I'm more into the general idea than this specific execution
Radiant heat using pumped hot fluid (I think usually a water antifreeze mix in a closed system) in tubes attached to the underside of the floor, seems like the closest, safer mix. Could be reasonably solarpunk if the source of heat is good
Did you just invent UFH? ๐
No, just recommending it since it sounds like what they're looking for. Some of my relatives have a house with it
Technology for a Solar-Punk future.
