Efficient, fast, and versatile. Blichmann's newest burner is appropriately named HellFire ! This patent pending dual mode burner has the option of running quietly in efficiency mode at 80,000 BTU/hr to maintain a rolling boil up to 20 gallons. The other mode being the high power mode that will run at 140,000 BTU/hr is perfect for getting that boil going in no time. This burner also includes a patent pending heat shield to prevent the massive amount of heat from scorching your valve, thermometer and sight glass while directing it to your wort.
