What kind of heat are you running for your garage for your cobra?

[riggsjr]

Looking to add some propane heat to my 32x24x9 well insulated garage. Garage is made out of 2x6's. I have 5 windows,1 man door and 3 garage doors. I use the garage mostly for storage but want to add heat to work in there on weekends. No not looking to keep the cobra warm all the time .Been doing a little research and I am now thinking about OPTION 1.... Something like a Payne house furnace for the money .A 60,000 or 80,000 BTU unit.I would still need venting, duct work, gas line and filter box. This furnace achieves up to 92.1% AFUE.I would like to mount this unit horizontal up in the air to save space.My only concern is the condensation trap freezing when not in use.I would think also that these units are fairly quiet.

OPTION #2 is a Mr. Heater Big Maxx or Hot Dawg hanging unit which this unit I heard is ver noisy. Maybe like a 60,000 BTU unit.

Wondering if you have a garage with heat what type of heat are you using?
