I had a 24' x 28' - 2 story garage, that was insulated. I found a used furnace from a house for $200. I had a heating/cooling person switch it to propane for $100. I ran the gas line, and ran one vent line for downstairs and one for upstairs. Downstairs I just had 3 T fittings dumping the air from the ceiling, funning between the floor joists. Upstairs I ran vents like in a house. I kept the thermostat at about 50 degrees all of the time, and when I went out to work in the garage, I would raise it a bit. Normally it cost me around $300 a year to heat the garage.

I sure miss that garage!
