On Toasty walls

Don’t you put radiant heat in the floor?
In my opinion – that’s a bad idea. Building code says if you put heat in the floor you have to insulate R10.
This forces you to thermally isolate the living space from the earth.
Imagine it’s really cold outside – 55 degrees from the floor is a nice and free heat source. If it’s hot, 55 is a nice cool source.

Residential code targets 64 based on comfort. I avoided the issue by designing supplemental heat into the interior walls & tire wall to avoid the issue.
