I checked on the heater about two hours after starting it. The inside of the greenhouse was 20 degrees warmer than the outside. Unfortunately, I seem to have triggered a safety shutoff switch at some point. Everything was ok, though. I am going to try to mount it in a different place. It stinks of diesel, and I don't like being around it when it is running, but it is certainly powerful. I had the thought today that I could easily heat both my high tunnel and greenhouse with just that one heater. I was planning on using the high tunnel more like a greenhouse, anyway, with tables of potted plants. I may have to mount the heater externally, to give it enough space to not overheat.

And I am hoping to not have to run it much, maybe 4-6 hours on a cold night, but at this point that is only occurring once or twice a week.
