Blichmann Floor Burner
A 72,000 BTU/hr burner that is a great blend of heating power and efficiency - and does so whisper quietly! In addition, low flame combustion is clean, wind performance is outstanding, and the heavy stainless construction is built to last a lifetime. For operation on natural gas expect 15% less power and 15% longer heating times due to the lower BTU content of natural gas vs. propane.
Blichmann also documented that the published BTU of competitive burners varied wildly from actual measured results. And measuring the performance is straightforward: simply run the burner for an hour at full power and measure the weight of the propane used in lb. Then multiply the weight in lb X 21,000 to get the burner rating in BTU/hr. For example. the Bayou Classic has a published rating of 180 KBTU/hr but only measured at 68 KBTU/hr!
