Are you up for the money saving 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. The flow temperature is the temperature water is heated to before it goes around the radiators in your home. Reducing this could save you money – and the online guide below shows you exactly how to do it. Changing the flow temperature will not affect the temperature of the hot water from your taps and showers.

We know that not everyone has the same type of boiler. You don’t need to know the make and model – the guide takes you through pictures, just click on the one that looks like your boiler. It’s quick and easy.
