Households looking to cut their energy bills are urged to make a simple change to their boiler settings, which could save them over £100 a year.
Charity Nesta has launched a money-saving boiler campaign in partnership with Which?, Energy UK, EDF, E.ON and Octopus Energy.
Nesta says households using combi boilers should set the ‘supply temperature’ lower to be more energy efficient and save £112 a year, without compromising the temperature in their home.
Reducing the temperature of your boiler by 10C could save you over £100 a year
What is the flow temperature of a boiler?
The supply temperature is the temperature to which a boiler heats radiators and works more efficiently if the temperature is set at 60C. However, the boiler flow temperatures are often set much higher.
According to Nesta, changing the supply temperature on your central heating boiler has no influence on the temperature of the hot water from your taps.
Instead, it means your boiler is in ‘condensation mode’, recovering heat that would otherwise be lost.
Households that run their combi boiler at a lower temperature should leave the heating on for about 15 minutes longer to heat their home.
But Nesta’s research shows that lowering the temperature from 80°C to 60°C saves nine per cent of total gas consumption, or £112 for an average home.
How to change your boiler setting
The boiler supply temperature is different from that of your thermostat and is controlled by two knobs or knobs on your boiler – one for heating and one for hot water.
You cannot do this if you have a hot water gas tank.
Settings usually vary from boiler to boiler, so it’s worth reading the manual to find out how to reset yours.
Saving energy: Many households are trying to reduce their power consumption as bills rise
The heating knob usually has a radiator icon, but Nesta has a step-by-step guide to help you through the process.
Some homes can be heated at supply temperatures below 60C – the lower you set it, the more money you will save.
However, for older houses that are poorly insulated, 55C can be too cold and take a little longer to warm up the room.
Nesta suggests lowering the supply temperature to 50C when it is milder outside and to 60C on the coldest days of the year. It is safe and easy to change your supply temperature several times a year.
Lowering the temperature in 5C increments depending on the weather can save 12 percent on your gas bill, according to Nesta, which works out to around £150.
