Does it really make much of a difference ? My garage is insulated except for the door and I have an electric heater that will get it toasty in the winter. In the summer I have the door up and a fan on anyway. The only time I heat the garage is when I'm going to be working out there. I turn the heater on about 1/2 an hour before and it's fine. Actually I never need to turn that heater up all the way. Seems like it might be a hundred bucks or so and a couple hours for something I don't need. What's the opinion on this ?
