Ronnie mentioned "climate control" We spend thousands on these toys and deprive ourselves of a nice place to work on them,(for those in a cold climate.) It doesn't get really cold here in Seattle, but I'm not hanging out in the shop when its 40 degrees! I have a 45k BTU furnace in the shop, I can get the place cooking in a few minutes. They cost around $600. If you aren't wound up about having it installed to code, you can DIY. I did the last one at my house and it worked for twelve years without any problems. I had to pay to get this one installed, it was $1600. I have real stucco on the wall outside of where the vent goes and its about a 25' drop. No experience with stucco and I'm too old to get on a ladder that tall! Highly recommend a Hot Dawg! I never let the garage go below 50 degree in the winter. Probably wasting money, but I just like the idea of my toys not having such a large temperature swing.
