I could not have got a better heater than your Aerotherm heater.  I live in Hamilton Montana and have an unheated hangar.  I leave it on all winter and everytime I go out to fly I don't have to pre-heat because its already nice and warm.  We had 10 below temperatures here in December and the airplane stayed completely warm.  It works great on my Citabria and I can take it to my fly in ranch in the Selway Wilderness of Idaho and run it off the generator back there.
