I am currently finishing a new woodshop under my garage. I am looking for the best way to heat it. I understand that with a woodshop, there will be a lot of saw dust, etc, so I should stay away from open flame systems?. My house is heated with propane, so that is an option. I would also like, if possible, to allow some of the heat to filter up into the garage, but that is not the priority. Help please.
