Garage Heat?

I use this and paid $100 for it from an estate sale. 24,000 btu NG in a 28x36 attached garage! I don't pay the bill so I don't know how much it costs to run, but it runs all winter and I keep the garage about 50* and turn it up when I'm going out to work! Keeps the garage warmer than the house! Geof

FYI, electric heat is the most expensive heat you can use!!

I have the same one and bought it used for a couple hundred dollars off Kijiji. Heats my 2 car garage with 9' celings in the coldest days to 70 plus degrees. I put a decent celing fan in to help keep the heat lower to the ground. Mobile home or trailer furnace sounds interesting though. Andrew.
