This is what i have and it does the job very well. My garage is very well insulated and not very big. Im concerned of its safety and if its ok to leave on all winter long. Ive left it on for a few days at a time with no issues and most of the time the only the only thing burning is the pilot light. My biggest concern is the wall opposite of the heater is my 1 1/2 yr old sons bedroom. I thought of putting a baby monitor in the garage so someone inside could hear the smoke alarm going off in case of a fire and to my advantage someone is always home.
