For those in colder climates these next 5 or so months, I'm curious as to what you use to heat your garages? I've got a 2 stall and I doubt any options from Lowes are gonna get the job done.
"I'm curious as to what you use to heat your garages?" My unattached but insulated 2 bay has an oil fired hot air heater . Common around here to use a (used ) hot air Mobile Home (Miller ) type or other small home oil/gas fired hot air unit. Electric is simpler install but typically burns $ ... . Wood heat is option. Mostly depends on fuel source. (Local building codes should be a considered.) Thermostat keeps garage just above freezing in coldest weather or can warm it up for work in a half hour. In coldest weather timer warms it up for me in AM and once overnite. . . . have fun
We have natural gas so I use a 70,000 BTU forced air unit hung from the ceiling to heat the 1480 sq' garage. I set the tstat at 55 all winter and turn it up to 65 when I am out there working. I have a few ceiling fans on low that I use to move the air around. The garage is 2x6 construction with insulated doors, R19 in the walls and roof, tyvek wrapped with 1/2" foam board and 1/2" insulated siding. Seems like the heater only comes on when i open a door. Stoping the air leaks is key
I should've mentioned I do have a wall-mounted propane heater in the above garage space/loft running to the tank outside. It's a detached so I'm tempted to tap into it for the garage area, but I'm also planning on finishing that space above and put in a mini split for heat/cooling. i could run another unit downstairs. Of course, none of it's currently insulated, so that should be step 1. Thanks guys!
In North NJ I leave the heat on 24/7 at 55F. Then the tools and cars arent frozen and its a comfortable work environment. With the heat on constant it barely runs as long as you arent opening doors.
Natural gas heater in my uninsulated 2-car garage. Don't remember if it's 20k or 30k BTU but it gets stupid hot in no time. It's probably too big for my little garage but I got it at a yard sale for $75.
