Propane heater safe for garage?

[gnihcraes]

Never had a problem with my setup. Just don't run propane for long. Kerosene has little smell once burning, just a giant candle.

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.

If you have an optimal burn with a blue flame and no smoke, no CO should be generated.

If the burner is running lean or rich, CO can be an issue, especially with poor ventilation.

Generally propane is very safe.

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

or slip on the ice created from the moisture, then crawl to where the cell phone went to, to call for help. Or an ambulance.

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.

THIS, exactly what I have in my shop. Works great, it?s been running great for more than 25 years. Keep the shop at 50, if I want to work in there I kick it up a little. Of course I am working off a 500 gallon tank, might not be great with a small tank.

Kerosene heaters were a craze in the 80s, I can’t tell you how many 5 gallon cans I filled at the lumberyard I worked. It was like 79 cents a gallon. Now it is so expensive I wouldn’t use it for anything other than lamps. I remember homes of people who used them a lot that had oily, sooty residue on the walls, no thanks.

Mount one from the ceiling if there is room. Only way to do it right.

I use the Mr. Heater propane cooker heater I used to use in my ice fishing hut in my garage (no longer ice fish). It's this model: https://www.amazon.com/Mr-Heater-F24...94010723&psc=1

Not fancy, but it does the job.

I have it aimed towards where my wife sits and about 5 ft from her. We usually just use it on the lowest setting to conserve propane. Even though I'm 45 degrees and 5 feet away from the heater I get sufficient heat to be comfortable.

Only a 6' hose but the heater is the full length of the hose away from the 20lb tank and sits on the concrete floor with nothing else near it.

Given that it was considered CO2 safe for a 4'x7'x6.5' nylon ice fishing hut, I figure it's safe for a garage. Been using it for several winters without a problem. The only down side it I look like a meth lab owner when I show up at the propane refill place every 3 weeks with 2 empty tanks to refill.

I also have an 18000 BTU Mr. Heater Big Buddy heater, but I need a filter for it for use with the 20lb propane and sometimes it's a pain to get it started. The other one is simple and reliable.

Own up to it- you just light your farts in the tent.

By the time you figure this out. You could have had a mini-split installed.
I run a 110v unit in the reloading building (13x15) 64 is t-shirt comfortable.
2-220v in the shop (30x24) with 18' ceiling and 2 ceiling fans @ the 12' mark on each end of the shop. 1 hr running both @ med fan and ceiling fans keeps the shop @ 60, 2 hrs and it's t-shirt weather.
.
Heat in winter, cool in summer. no hoses to trip over, worry about condensation on tools, machinery, or reloading equipment. Surprisingly it's not a serious hit electric bill wise, but i also don't run them 24/7

I use a propane heater in my garage occasionally and just open the door slightly to allow for fresh air intake. They put off so much heat to door being open a little is not an issue.
