I have a garage that is 20' depth x 28' wide and the ceiling is 8' high. The walls are block and the outside I had 3/4" insulation board with furring strips and siding added on for aesthetics. I put 4 new 36" x 36" double pane windows with argon in the garage as well. There are 2 on the east wall and 2 on the west wall. I had ceiling rafters and a i-beam put up as there were only cables holding up the roof rafters. After the ceiling rafters & I-beam were installed I placed R12 or R19 insulation with a covering of plastic over the insulation and ceiling rafters. I then added 3/4" insulation board over that as one side is shiny silver and helps with lighting,not only insulating the place more. After all of this I noticed I got a humidity problem and the humidity levels were near 80%. So I bought a whirlpool 70 pint dehumidifier. I can get the humidity levels down to 48% but no lower. This brings me to the new problem and finding a solution. I live in the northeast of the usa & the weather is getting colder especially at nights. I spend alot of time in the garage and I need heat. At least to 65-69 degrees while Im in there. 55 when Im not. I bought two charmglow propane wall hanging heaters that were 28,000 btu's & open blue flame only to find out that I cannot get them hooked up if I house a vehicle in there. Which I do. So I had to return them. Im looking for a vented propane wall hanging heater for this garage or something that would help heat the place and keep the mositure down and keep the temps mentioned above. I also understand that adding a vent free type propane or gas heater will add to my moisture problem. I was referred to use baseboard heaters but Im concerned on how much it would cost being electric. I probably would use the heat at 65-69 degrees 20hrs/7days a week from October to May(about 7 months). I may turn the heat down to 55 degrees for the night. I was told that electric heat would help the moisture problem(which I would like to stop using the dehumidifier). They also said with gas,propane,& oil prices of today, that electric heating costs arent so bad and are a bit better nowadays. But Im still concerned and still wonder how much heat they would throw off and what the temperature would be using 1,2 or possibly 3 baseboard electric heaters. Anyone have any better advise for me?
