It's a bit overkill (garage is around 15X30), but I can comfortably work in there.

Mr. Heater - America's Most Popular Portable Heaters

 

Holy crap. For 450 sq ft? Wow.........
You're gonna light your *** on fire.

 

Damn, make sure you crack the door. That SOB is going to eat up all your oxygen! But you sure will be warm.

 

I fired it up and by the time I got a tarp on the large door (guy did a real **** poor homemade dual swing out), it was already comfortable. As I type, she's at least 75 floor to ceiling in there.

 

Kerosene is damn expensive here. You running it on diesel?

This is what I need.

 

Dang man i think ya might of went alil overkill on the heater!!! But on the brightside if the power ever goes out you can still cook steak with it

 

Well it takes 120 AC, so no power, no heat. But it'll run on #1 and #2 diesel/fuel oil, kero, and jet fuel.

 

we have one of these i use in out shop (20x50) and it's one of the old bigger ones and that that thing has to be turned off after about twenty minutes it'll get so hot but i love it and it goes off kerosene

 

We used to run a 500,000 BTU unit in a 50x100 tent at our old shop. It used propane as fuel and had a 500gal tank to feed it. I think that's how big it was, abot 3ft diameter and 6 ft long. It worked well, but when you worked on top of a machine you sweat your ***** off. Ground level or on the floor it was still damn chilly!

 

They had a unit that big there as well, but it was a multi-fueled unit as well (diesel, kero, etc..). But at a price tag of $1300, I'll pass. But with a building that big, need to leave it run overnight.
