I've been a hidden fan for awhile now. I started my cinder block cedar smokehouse. Im to the point now for insulation and interior finishing. I have the offset fire box but was also wanting to add an alternate heat source so when it's time to go to bed I can. Im looking at the mypin with a thermocouple and a 1500 watt burner from brinkman as advised on here. But is this an option with the offset fire box as well or is propane burner the better option?
