I'm new to this forum and just starting out finishing my 2.5 car garage. I have blown R30 in the attic and installed r13 in the walls. I don't spend a whole lot of time in the garage (two young kids) but enjoy it when I do. I'm having a hard time deciding on heat options. I live in Michigan so it gets cold in the winter. In not sure if I should install a 240 electric or natural gas heater. I don't have 240 at the garage or a stub out for NG but both should be simple enough. With limited time spent out there should I just go for the electric option? Is it worth the extra expense for the NG? My garage measures 22x33. Any advice would be great.
