Yes, I heat the double garage (workshop) all day for about $2.50 - and only on the days I use it. I could not be happier with the nice quiet heater. Early in the morning, when the whole garage is not heated up yet and I am in a tee shirt, I go over and warm up my hands over the rising column of heated air. Other times I just sit next to the little heater reading again what Nick recommended for a specific task... Feels good!
