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.
Mine started throwing an E8 code this morning and won't fire up.
Going to order another and then tear this one down to see what happened.
I ran the heater for two hours this morning. The shop is a little more than 600 sq/ft semi insulated, and the starting temp was -2C/28F. After two hours, with an outside temp of 2C/36F the temp in the shop was 7C/45F. I burned a little less than 1.25L of fuel. So I don't think there's any way this thing is 8kw, or 27,000 BTU. My propane heater is supposed to be 30,000 BTU, and it would have brought the shop up to 15C in less than half the time. Watching some video reviews, one guy tore down a 5KW and an 8KW, compared the parts and said they were identical. So maybe some shenanigans going on there.
Still, not bad for the price and not bad for the amount of fuel burned. I'm going to set it up outside the shop, run the hose in, start off using both heaters, shutting off the propane when everything is up to temp.

Really, they're cheap enough you can do that. In fact, after running this one I kind of regret not buying the kit version, it comes with a 10L tank, and installation can be completely customized. Maybe next year.
Let us know what it turns out to be.
