Replacing you existing boiler

Boilers account for around 55% of what you spend in a year on energy bills, so an efficient boiler makes a big difference.

Replacing an old gas boiler with an A-rated high-efficiency condensing boiler and improving your heating controls will significantly cut your home's carbon dioxide emissions - and could save you as much as £310 a year.

How much could you save?

This will depend on how old and inefficient your existing boiler is.

Old Boiler RatingAnnual SavingCarbon Dioxide saving per year
G (<70%) £310.00 1,200kg
F (70-74%) £205.00 810kg
E (74-78%) £155.00 610kg
D (78-82%) £105.00 430kg
These are estimated figures based on installing a new A-rated condensing boiler and full set of heating controls in a gas-heated, semi-detached gas heated home with three bedrooms.

Todays modern boilers are more efficient for several reasons, but their main advantage is that they are all condensing boilers. 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 condensing boiler has a bigger heat exchanger, so it recovers more heat, sends cooler gases up the flue and is more efficient. Sometimes the flue gases get so cool that the water vapour in the gas condenses out (hence the name). When this happens, even more energy is recovered from the condensing vapour, and the efficiency gets higher still.
