I'm putting forced air wall heaters for 2 bedrooms (Markell Brand). They have 1000,2000,3000,4000w units. The rooms are upstairs, about 230 sq ft each, 2 double pane windows, r19 walls, r38 ceiling. Also I live in Delaware.
My first question is, what wattage should I choose? I would prefer the 2000w small footprint heaters. My rooms are well insulated and I think the downstairs heat will rise and contribute a bit. I'm also not going to go off and kill myself if it only heats to 68ish on the really cold days. Thoughts?
Second Question, I'm putting foamboard on the walls they will be installed (cape cod so there is a wall between the room and the ceiling). Can I put it over the heater installation or should I leave the back of the unit exposed to dissipate heat?
