Garage heat

If you could dig a small trench (before the ground freezes) you could run a 220 line and if you got nat. gas they sell that yellow plastic stuff not very expensive run it to your fuse box and main gas line and I and others on the site can help you with the connections. Than you would have a lot more options. Been working on my barn, about 160 feet away ran 200 amp service and 1 1/4 gas line. gas line not finished with the gas line yet but about 60% done electric is all finished. You don't need 200 amp unless you are going run a lot of stuff 6 gauge will usually work well. Or you could just do one but if you are digging you might as well at least run both and just finish one at a time. The electric is easy to do. Than you can buy that big compressor. lol
