23 Best Boiler Brands of 2019 | FurnaceCompare

A residential boilers efficiency rating is typically measured by its AFUE (Annual Fuel Utilization Efficiency). Commercial boiler efficiency is often measured by combustion efficiency rather than AFUE. The fleet efficiency of a particular brand is the average efficiency of all of the models sold under that brand name.

key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.
