Shop Heat
My weather is very similar to yours, perhaps a bit colder. My shop is odd, 30x40 with a 10x40 room built along one wall. That leaves 20x40 floor space but the ceilings in the shop are still 18' high and the area above the built in room is part of the shop volume. The best thing I did was insulate everything. I bought the place with no insulation, and it made a HUGE difference. Just the insulation alone gets me 10-15 degrees above outside temps. I put in a pair of 60" fans at the peak to push the warm air back down in winter. I use the heater listed below on top of a propane bottle. It works like a charm. To preheat, I turn it on for about 15 minutes and turn the fans on low. If it's 35 outside, I start at 45-50 inside, and the heater will bring it up to the low 60's. That's plenty good for me, I just wear an insulated sweatshirt and I'm good to go. A couple of nice things about the heater, it's quiet, and doesn't use much fuel. I use a bigger (as in fatter) propane tank, that helps keep it from icing up when it's on high.
