If you have a gas combi boiler, you could save up to £112 a year

Are you up for the boiler challenge?

If you have a gas combi boiler, you could save up to £112 a year on your gas bill by changing a single setting.

A combi boiler – a boiler that provides both your hot water and heating – works best when it heats radiators to 60°C or below. The flow temperature your boiler is set to heat at may be too high – it’s not unusual for boilers to be set between 70°C and 80°C. Reducing this could save you money – and the online guide below shows you exactly how to do it.
