What is boiler efficiency? - OVO Ener

While modern condensing boilers have to be A-rated with an efficiency of 90% or more, older non-condensing boilers can be a lot lower. A boiler over 15 years old could be 85% efficient and one over 20 years old could be only 70% – definitely room for improvement. Another sign of efficiency are ratings, so we’ll get on to those next.

Replacing My Boiler | Energy Saving Tru

Heating accounts for about 55 per cent of what you spend in a year on energy bills, so an efficient boiler makes a big difference. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue (a pipe for extracting fumes and supplying fresh air to the boiler).
