Boiler information

What is efficiency?

The boiler efficiency is the ratio of the energy input to output. This means that high efficiency boilers require less fuel input to produce the same amount of heat to the system as lower efficiency boilers.
	In any boiler there are heat losses, some in the flue (the combustion products are hot and therefore carry part of the heat energy out of the boiler into the outside air), and some through the boiler casing into the boiler room. If the total amount of energy produced by combustion was transferred to the heating system water the efficiency would be of 100%.
