Direct efficiency. This method calculates boiler efficiency by using the basic efficiency formula-η=(Energy output)/(Energy input) X 100. In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency-E= [Q (H-h)/q*GCV]*100. Where,

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.

Aug 13, 2018 · The biggest difference between condensing boilers and “conventional”, non-condensing boilers is “efficiency”. The most efficient boilers keep heat in the house rather than letting it escape through the chimney or vent pipe. An ultra-high efficiency boiler is able to keep more heat in the heating system, but the side effect is condensation.
