Garage heater problems!!

Thanks fourspeed, t-stat is installed, now trying to figure out what to do in the ceiling, here is the link of the thread I started bout the insulating. I plan on keeping the t-stat right down as much as possible, especially when I am not in there. Just want to keep it warm enuf so $hit (aerosols, liquids etc) doesnt freeze.
