What is the BTU of a Forgemaster?

BTU is a standard measurement of heat produced by a furnace. Each Forgemaster burner will produce about 50,000 BTU’s when operated at 8 pounds of propane pressure. Compared to a normal household furnace (100.000 BTU’s) you might think that’s not much heat produced. A two burner Forgemaster produces approximately the same heat necessary to heat a 3-bedroom house, but is confined to an area of about 2.5 cubic feet.

Blacksmiths and farriers generally think in terms of degrees for heating steel. A Forgemaster operating at welding pressure (12-14 psi) will produce in excess of 2500 degrees F.
