Mark,
We use the propane unit to take the chill off of the garage.  The only 
problem that we see is getting too close and burning your self or possibly 
starting a fire.  You do need to set it out away from everything because the 
face gets very hot.  We have about the same garage footage uninsulated and a 
little drafty.  It does not get that cold here but we are close enough to the 
water that with the winds it feels colder.  It does take a while to our 
garage to something like a stable temperture.
Bob and Annice
