10kW still may not be enough for a 2 car garage. My recollection is somewhere between 40-50k BTU is needed for this space, and a quick google search agrees. And I'm sure it's probably higher up here in the frigid north (I'm in Montana, got down to -13F/-25C over new years, one day it didn't get above -3F/-20C, so I understand the cold). 10kW is only 34K BTU. I'm not surprised 5.6K didn't even touch it. If I can't do propane or natural gas, I'm a big fan of the dyna-glo convection kerosene heaters. I just looked, the one I use is 23K BTU. $100US or thereabouts. Or there are various tri-fuel units available. Keroscene is not odor-free, but it definitely isn't any worse than you'd find in most garages, etc. On Thu, Jan 4, 2018 at 10:24 PM, V G wrote: > On Mon, Dec 11, 2017 at 6:24 PM, John Gardner wrote: > > > Two-car garage?
