Combustion air in is taken from the outside.
Exhaust is run through a marine bulkhead fitting.
It's a steel building so no worries about fire.

This is the way. you can get them to run on a waste oil diesel mix too if you are really cheap

Yikes. That's a lot of Canadian Pesos. Maybe since my garage is already relatively warm it's not as bad on the pocket book.
If the electric gets you above freezing, how much warmer does the diesel heater get ya?

Thank you. In this thread is the first time I've heard about these units. Much appreciated 👍

I can get my 500sq/ft shop up to about +15c with it. Plenty warm with a shop coat on.
I've run a bit of waste oil in mine but I've got so much stale gas to use up, it's just easy to mix it 50/50 with diesel.
I installed mine last night. It really pumps out the heat. If their rating is accurate it's almost 30,000 BTU, and it seems like that's possible. The controller, in auto, controls pump speed, and heat output based on temp setting and would probably work well in a smaller, better insulated space, or more normal temperatures. My shop was around 0C and I had it set to 10C. At that setting it ran the pump at a lower speed so the heat output was not enough to raise the temperature significantly. You can run it in manual and set pump speed, so that's what I'll do.
The muffler and associated piping gets really hot, so there's opportunity there. I tried putting a bike radiator on the output and it got really hot, really fast, so I'll be putting a rad and fan on the exhaust before long. May as well try to maximize all the available heat. One problem is that it's a little loud. Perfectly fine for a normal shop, but I do a fair bit of listening in my shop, and I found it annoying. I will be installing it outside the room, in the main part of the barn and piping the heat in.
So far I'm pretty impressed. It cost half what I paid for my ventless propane heater and should do the same job, maybe even more efficiently.
