Pretty good! I built a stove from a 55 gallon drum, a Sotz kit. That was rated at 150,000 BTU. Huge firebox 32 inches long.
This is the Sotz kit on steroids.
For comparison, my current stove is a top of the line Jotul, rated at 55,000 BTU. I loved the old barrel stove but the girlfriend hated it! Said it was ugly and she would leave me if we didn't get a Jotul.
Women, go figure.
