Space heaters for garage/shop?

I'm a fan of those little wall mounted propane infrared heaters. Cheap and will heat you up quick.

Not electric, but I use a 80K BTU propane mushroom heater in my 800sqft garage. Heats it up right quick. Not the most efficient if you are going to use it constantly, but for the few times I'm out there and have to work on a car or my bikes, it easily makes it T Shirt weather.

What wall heater do you have? Replacing it with another cadet may well be the simplest and best way.

Also, what is the size and insulation of your garage? Those things matter.

Essentially why I use 80K BTU to heat 800sqft. haha.

Oversized 2-car. Cars are never in it I did insulate the ceiling/attic portion last year with double layer of R-15/16 if I recall correctly. That helped. But the lack of insulation behind the drywall and the garage door are certainly not helping.

Not opposed to a propane one either.

This looks stand alone, right? no plug in, just make sure it has fuel and fire it up?

You connect it to a 20lb tank with included 10' hose. You could probably get away with using the smaller one:
Run times on the smaller one are way longer than the first one I linked.

I use one like that to heat up our garage when I need to work on something in the winter... It will take the edge off in a hurry if you crank it all the way up. I'm usually not trying to get it warm, just keep my hands from freezing while I'm wrenching on one of the vehicles.

Also, yeah, if you turn it all the way up it will devour a 20lb tank in a few hours. Mine is 20-80K, so I turn it way up for about 5-10 minutes while I'm getting stuff ready, then back it off while I'm working.

the electric infrared quartz heaters work pretty well. They tend to heat surfaces rather than the air, so they don't work as well in an empty room but you'll "feel" the heat more. you're limited to about 1500 watts on a 120V outlet, but even that will make a noticeable impact on your electric bill if you run it a lot!

propane might be the way to go, I just never like burning anything indoors.

I wouldn't run a propane heater in my house, but I don't consider my garage inside my house. With the air leaks around the roll up doors, I've never had a low oxygen issue. If you are concerned about that, you could always life your garage door slightly to vent in some fresh air.

That's why I like the infrared ones, they heat things (like me) and not air. You can run the one I have on high for days and days on a 20# propane tank.

Vent free

If you have a fuel line to the garage, invest in a Reznor ceiling heater.

I tried one of those 60,000 BTU tube style propane heaters. It worked OK, but you have to keep a garage door open some to avoid carbon monoxide buildup. When I needed the heat the most, I kept getting big bursts of ice cold wind and blowing snow in the garage. It was tempting to just close up the garage and risk the carbon monoxide, but then I read up on what it actually does to your body and brain and realized that was stupid. And the propane costs were higher than I expected.

In the end, i found that leaving the door open between the garage and the house worked better. That way I use the house furnace to heat the garage while keeping the garage door closed. The natural gas costs were cheaper than all the propane I was blowing through.
