Not only good for garages but the house too. I used to have mine in my basement then we quite using the basement. So last year I brought it up stairs and mounted it in front of my fire place and use it during the day to heat the kitchen and living room so the furnace wasn't running all day, and it cut my heating bill by 30%. The bed rooms and bath rooms I just left the doors open, but your not in there that much during the day anyways. Only difference is mine is the inferred not the blue flame
