I have searched these forums looking for opinions on the efficacy of air heaters but haven't been able to find anything.
In short, do these things work? Not as a complete source of heat, but as an efficient supplement perhaps? I live in the mountains above
San Diego and we get a lot of sun. The house faces south and gives me a good deal of winter sun/warmth, but when it falls into the 30s
or 20s at night my propane wall furnace gets going. I have a tenant moving in upstairs and he wants to use a ventless propane heater instead of the wall furnace up there but that idea makes me nervous . I would much prefer a solar solution to his expected heating needs. (My two cats keep me warm on winter nights, and they run on Friskies, but my new tenant doesn't have a cat!)
