Need your help guys!
I have a 20' x 20' attached garage that is extremely high in humidity. It is on the north side of my house, on a concrete slab, with insulated concrete form perimeters. Both the walls and ceiling are well insulated, and the only thing bringing house air into it is the central vacuum exhaust. My wife parks her car in the garage, and I recently installed a small natural gas radiant heater (25,000BTU) to melt the snow from the car. Works great, aside from the stink. The garage has a good drain in the floor. I'm aware that the car is bringing a fair bit of moisture into the garage, but we best not go there:laughing:... As she points out, we had moisture issues there before she parked in it.
Here is a link to the heater I've installed. Local building codes do not require external venting for a heater of this size, although the mfr. specifies an open 8" hole in the wall for fresh air. I haven't done this yet.

The garage is presently sitting at 78% humidity, while the house is around 45%. Outside temperatures are around freezing, but it typically sits around 10 degrees (Celsuis) below zero here in northern Canada. My window is dripping, as are the door hinges, and the garage door door. A bit of black mold starting in the corners too... yuck.
Any suggestions on where I should start? I'd prefer to try and reduce/eliminate the source(s) of humidity before I throw any power (dehumidifier, power vent, etc) at it.
thanks for your help. This is a great forum....
