Propane heater safe for garage?

[Martinjmpr]

With these freezing cold temps I still want to work in the garage. My little electric heaters aren't keeping up.

Thinking of this style of heater:

Sunnydaze Decor, 40,000 BTU Forced Air Propane Heater Auto-Shutoff, Heat Type Other, Heat Output 40000 Btu/hour, Heating Capability 225 ft?, Model# BAO-118 | Northern Tool

Are propane heaters safe to use in a garage where I might be working on vehicles? I think ventilation is fine I'm more concerned about flammability.

Also my other hobby is collecting and restoring old Coleman lanterns, the kind that use liquid fuel. So I might have fuel exposed if I open up the tank (fount) on one of my lanterns. Obviously I'd have the heater far from any work space but I still worry about any kind of open flame when I'm working around gasoline.

What are you all using in your garage/workshop/barn?

Would kerosene be any better? My only gripe with kero is I hate the smell.

I used one for 3 yrs in my shop, then went to mini-splits. The only issue is. DO NOT TRIP OVER THE HOSE!

I also used a 12' ? supply line from the tank to heater. If you don't have any fans in the area, get 1, or 2. Once you get it dialed in you'll be able to work comfortable. Remember propane heat produces condensation, so adjust accordingly.

Kerosene works great. More costly than propane. I used propane to heat up and switched to Kerosene to keep it warm.

Is carbon monoxide a thing you enjoy? If so burn a hydrocarbon fuel in an enclosed space!

Fuck Kerosene in any environment you want to:
A- Not smell like kerosene
B- Don't want the oily residue everywhere.

Another by product of combustion is moisture- That's why I never had any heat source in my shop other than electric.

This sells much better. Just saying...

So much this.

It's very safe.

Only three concerns:

1. You need a carbon monoxide detector. They are cheap.

2. You cannot store gas cans or any solvents in that garage.

3. You should have a full sized dry chemical fire extinguisher nearby.

The products of combustion of propane are H2O and CO2. CO is only produced if there isn't enough O2 to support complete combustion. As long as there is enough make-up air so the O2 level in the garage doesn't get low, you should be fine. Clint's idea of a CO detector is sound and would provide nice piece of mind.

As others have stated, it's going to make quite a bit of water vapor which will condense into liquid water on any cold surface.

Sounds like the worst that can happen is things in the garage get wet and you die

If I was going to do something other than electric it would be a Reznor or Modine horizontal forced air SEPERATED combustion heater.
They draw your combustion air from outside and combustion is in a sealed chamber - condensation is virtually nil and minimal CO risk.
