Eden pure heaters?

I have an Eden pure in my house I run it during the day in the winter. It raises my elec. bill by 50.00/month but saves me more than that in propane. It heats a room ok. I use it in my living room. My thermostat is also there so the heater isn't kicking on all the time. It might knock a little of the chill out of my garage but it sure wouldn't heat it. I use a propane fired space heater to heat mine.
