I’m currently using a beast of a torpedo heater. It’s a silent drive 220,000 btu heater. I run off road diesel in it. It will heat the barn to 60-70 degrees. I should be out there today and it’s around 10 degrees out so we shall see how she does. It definitely likes to drink the fuel but that’s the price of being comfortable I guess. I can’t wait to the floors to be heated.
I’ve also noticed you can smell it a bit more when I had the thermostat set to around 30 where it kicked on/off more. When it’s set at 50 and runs more, there is much less odor if any at all. First half hour, let it warm up, crack a window if needed and it’s great!.
So far this app appears to be working well. We shall see
