Anyone have any experience in heating a garage to use as a workshop over the winter? I live in NC so it's relatively mild weather, but winter temeratures do get low (30s, sometimes below). It would be nice to be able to do projects or work on the car or whatever (for example painting something would go much better in a warmer room.)
The thought of a natural gas heater appeals to me (I have gas service) except that they're expensive of course. Electric heat would be the easiest and cheapest up front, but I'm worried about outrageous electric bills.
Also, what about insulating the garage? I'm going to be drywalling it, and I'm wondering if insulating it would be worthwhile. It's already insulated on the wall areas that are adjoining the house, of course.
