Heating and hot water add up to over half of what a household spends every year on energy bills, so an efficient boiler makes a big difference. So how will a new boiler save me money exactly?
Older boilers lose at least some heat in the hot gases that escape up the pipe that is used to extract fumes and supply fresh air to the boiler (the flue).
Modern boilers are more efficient than older boilers for several reasons, but their main advantage is that they are ‘condensing’. A condensing boiler recovers a larger amount of heat from the exhaust flue gas and then uses it to heat the central heating water.
How much money will installing a new boiler save?
How much you can save with a new boiler will vary depending on the size of your home, but it will also vary depending on the thermal performance of your home. If your house is also thermally insulated with items such as loft insulation, cavity wall insulation, and double-glazed windows, you will keep in more heat. You can also save money by using lower temperatures on radiators that are bled on a regular basis, using a smart thermostat, and switching off heating in rooms you don’t use.
The Energy Saving Trust has published figures on what could be saved by installing a new A-rated condensing boiler with a programmer, room thermostat, and thermostatic radiator controls in a gas-heated home from an older boiler with a programmer and room thermostat.
Depending on the age of your boiler, from information in October 2022, you could save between £375 and £840 for a detached house and between £235 and £420 for a mid-terraced house. (Full calculations can be found here).
In addition, you might find that an energy-efficient modern boiler will be more reliable, and easier and cheaper to maintain.
