We are having a 32'by 28' garage built and I'm going to have the walls and underside of the roof spray foamed and the garage doors are going to be insulated. An LP gas line is plumbed to bring into the building. The roof framing is trusses and I wasn't going to have ceiling drywall installed, just open trusses. Might keep the garage a bit cooler in the summer.
My plan was a hanging forced air LP heater but looking over the crop of hanging heaters I have no idea of which one to choose. Any recommendations? Should I consider an LP radiant heater instead of forced air? Would one be enough (it's a three bay garage.)
Usually we get into the low teens and even single digits very occasionally, the objective it to just keep the garage in the ~55 degree range.
