I am considering a Harman P38 to be used in my workshop. The shop is about 700 sq ft and the insulation is ok. I live in Northern Minnesota as well. I am concerned that the stove will go out when it sits for a while after the thermostat is satisfied. Like when I would not be in there and the heat is turned down to say 45-50. Or can the stove burn a few pellets here and there and keep it self lit? I would rather have a pellet stove than a propane furnace if possible. Thanks for any input!
