Determining & Testing Boiler Efficiency for Commercial

efficiency. Boiler efficiency, in the simplest terms, represents the difference between 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 will result in substantial fuel savings.
