This is what I'm getting next year. I use wood now which works great but as others have said, mess, more work etc.
I replaced my fuel oil boiler in my house this fall with a propane boiler and plan to run a line from the tank to the garage. So one tank for house and garage on keep fill. Talked to the company that installed my new boiler and for a 75k btw Hot Dawg it's around $1500 installed. I have a 32X32 with 12' ceilings. Plan to keep it at 40 degrees all the time and turn up to 60 when I'm working.
