Interested in this, I have a house/property I am very interested in and wife is too. Anwyays, it has one of those, not a huge one, in the pole barn that is 30x46, so I wanted to know if it would make a difference. It is also insulated on walls and cieling, so imagine it would. Let me know. Also i Have been thinking of putting on in my current garage as I have gas ran to wher the fireplace would be, and that would also be just about 10 feet from where the heater would be. Just not sure what all else I would need there. There is only 1 electric plug and I imagine they require electric too? Let me know if you do it yourself and if it works. Right now I run an electric heater and it costs a few bucks a month to run in the real cold months, but my bike is out there and our cars.
