Good evening everybody. I finally have my garage and have my two cubs under a roof. No power or insulation just yet, but getting there. I wanted to heat the garage so I could work (play)during the winter. I was intending to use a coal stove that I had, but thought about getting a Rinnai propane heater with a direct vent, and avoid building a chimmney. After reading the Rinnai info on line I am a little conserned that a garage installation might not be the best idea, with the dust etc. Then I thought of everone here and wondered what your suggestions might be? It's not a machine shop like some guys have, just a garage. I offset the two bay doors to one side so I could park cars and work on the cubs all along the other side with a generous workbench at the back. It's 32' deep 30' wide and the ceiling is approx. 10 feet high. It's getting cold up here already!
