Garage Hot Dog heater

And that’s what is weighing my mind.....I’m thinking pellets would be cheaper

Although the exhaust is vented on the unit I do not believe combustion air comes from outside.

I heat two outbuildings with LP Gas ceiling mounted heaters. The brand I have is Reznor. Building one is 936 sq ft, Building two is 700 sq ft. A third outbuilding is a small craft studio at 140 sq ft that has an LP monitor wall mounted heater. All three units are vented outside and all three buildings are insulated (R 19 walls, R 30 ceiling) and sheetrocked. I have a 1000 gallon buried tank that supplies the three buildings. In 2019 it cost $1400 in propane. Like others have said, I keep it at 50 degrees and crank it up when I go out there, heats in minutes.

I use a Mr Heater vent free blue flame in my little one car garage without any issues with condensation. I have to keep it on low or it will drive me out. Problem is it uses a bunch of propane. I am getting it plumbed for NG next winter.

Remember your P38 is only capable of 38K BTUs max output and it will eat pellets trying to get there. I think it will struggle greatly to get you where you want to be.

I would look into the Toyotomi vented heater. It runs on kerosene and is extremely efficient. It's easily vented outside and uses outside air for combustion. I have the older version, the Monitor Heater, and it heats my garage perfectly.

I'm using the torpedo style heater and burning kerosene. Running it with the door closed is a no go. When it's not to cold I was running it with the garage door cracked open but it wasn't very efficient. I devised this little cutout to bring in fresh air. You can pull out the heater when not in use, don't forget to put some screening on the outside vent to keep the critters out.

Fair point. I was thinking originally of running it like Thursday nights thru Sundays and I be happy with 50 degrees. Probably will take hours to warm it.
I think the P38 would do it because I heated my house with that in MA. Firt floor was always 70 but I did chew thru 3.5 tons. Not sure how much it would chew thru to maintain 50 or so. I figure if it ate 2 tons at $259 a ton thats likely cheaper than propane? Ive got 4 of the 100 gallon propane tanks behind the garage but Burn pellets in the house so I only use about !80 gallons a year.

I have one installed by Eastern Propane a few years ago. My garage is 40x22x9 and it heats it no problem. My garage doors (3) are insulated so that helps. I would have to look to see the size if you are interested. It’s nice in the fact it heats the air not the objects initially. So I can turn it on and be comfortable in short order. I like the fact it is a closed system (intake/exhaust outside) as I do a bit of wood working and no issues with the dust.

I did a quick search and found my install info.

Modine Hot DAWG 60K BTU unit (sealed combustion) and vent kit was $2k, installation was $1300 but of course this will depend on your setup. This was in 2013.

Do not use anything in a garage that is not closed combustion. Open flame is a no no in a garage. Modine Hot Dawg has both closed & open & are awesome heaters

Plus you already own the stove so no out of pocket other than the wall thimble and some venting pipe....
