Boilers can be amongst the least energy efficient appliances in your home and account for
up to a third of all domestic CO2 emissions. As the current lifespan of a boiler is 10-15 years having an old
boiler could waste considerable amounts of your money.
A heating system that uses a high efficiency condensing boiler with the correct heating controls can save you as
much as 40% on your heating bills. A high efficiency-condensing boiler is the most efficient boiler available. It
converts more than 88% of the fuel it uses into heat, compared with around 72% for conventional boiler types.
