While running the risk of starting yet another "how do I heat my garage" thread, I've come across the idea of using a forced air, propane furnace. Recently, I found a couple furnaces on CL that were pulled from mobile homes and for the price, they seem like a great option for the garage.
It seems there are up-draft and down-draft style hot air furnaces. The one's coming from mobile homes seem to be down-draft style and might be more difficult to use how I'm thinking...
Has anyone setup this type of thing in their shop? My idea was that I could get it hooked up with the necessary power and then have a propane tank setup outside and pay the propane people to hook up the furnace. I was thinking that I would not need any duct work...just let the thing blow air into the 28x24 garage. It would also rise onto the second floor and heat the workshop upstairs. The garage and upstairs are insulated.
Any thoughts? Crazy idea or good idea?
