What is the difference between “steady state” efficiency and AFUE?
Steady State: An efficiency rating is testing only the efficiency of the fireplace when it is burning. AFUE (Annual Fuel Utilization Efficiency): Both the on cycle and off cycle are calculated in this rating. By including the off cycles (when the fireplace is turned off) a more accurate yearly operational cost can be estimated.
