Electric radiant floors in a mobile home
I'm planning on building a tiny mobile home a little less than 300 square feet total. I live in Northern WI and want better insulation and better building materials and designs than the manufactured homes. I also need some of common building chemicals out of my home.
I seem to do best with electric heat or radiators, but building on an 8 x 32 foot trailer has limited floor space that I don't want to be taken up with baseboard heaters and find that water radiators would probably be out of the question (or would they?). I wonder whether electric in-floor heating will lose too much heat below (even with a high R-value insulation) and result in high energy costs. I live in an apartment now and do well with electric heat, but I'm on the 2nd floor, so I'm not sure what would happen to efficiency with cold air below me. I could use a vented propane heater for back-up, but would like to rely on in-floor heating if possible. I prefer not to have forced air heat, even though this seems to be the popular way to heat mobile homes.
I will design the tiny home for good passive solar, but I may not always be able to depend on it, depending on where I am parked.
Also, given I would not have heat vents, I'm curious as to whether I would need a heat exchanger to keep the air turnover high and how I would do that, or if turning on a bathroom van or range exhaust a couple times a day would suffice in addition to doors opening in the winter. (I'm not concerned in the summer as I keep windows open most of the time.
