We have a house under contract in Eagle, Idaho. No humidity issues. Cold winters. Not North Dakota cold, but below freezing. No game room space in the house. Plan is to convert the single car bay from the 3-car garage into a game room by putting up a wall, running more outlets, better insulation, etc. But, what's the best way to heat the space? Ductless split? Forced air unit? Infrared heater? Electric wall heaters? I imagine a split or forced air unit would be the best, but I've never had to heat a garage before. Last tidbit is my wife sees this house as more of a temporary house and not for long term, so I shouldn't splurge too much on the conversion. If the conversion bid is too high I may just leave the whole space open and have to heat the whole damn garage.
p.s. Rough dimensions of the single car bay are approx 14' x 21', or 300 sq ft. Just wide enough for a row of pins on each wall.
