Consumers are being encouraged to reset the flow temperature on their boiler to 60C or below. Research from innovation agency Nesta found that this measure saved extra money than fitting a sensible thermostat, which saves a typical household £64 a yr.
This might cut £1billion from energy bills, cutting carbon emissions by the equivalent of six million transatlantic flights.
The easy change could save extra money than other free measures, equivalent to closing curtains at night, which saves £10 a yr, and placing foil behind radiators, which saves £3 to £11 a yr.
The fee-saving measure is one of the vital effective free energy-saving options, in keeping with the Nesta research.
Flow temperature refers back to the temperature that a boiler heats water as much as before it circulates across the radiators in a house.

Combination boilers work most efficiently if the flow temperature is ready to 60C or below, but boilers are sometimes set much higher than that.
A consumer changing their flow temperature is different to changing the temperature on a thermostat, which saves energy just by lowering overall room temperatures.
Reducing the flow temperature for a house saves energy because the boiler will run more efficiently, leading to rooms being heated more slowly, with only a slight temperature drop for homes with poorer insulation.
Nesta is launching a step-by-step online tool to assist guide people through the best way to turn down their combi flow temperature.
The tool is backed by campaign partners Which?, Energy UK, EDF, E.ON and Octopus Energy.
Madeleine Gabriel, Director of Sustainable Future at Nesta, said: “While the Energy Price Guarantee helps thousands and thousands to avoid bankruptcy from high energy bills, the actual amount people pay still will depend on their energy use, so it will be significant that anyone needing to maintain costs as little as possible this winter feels confident taking motion.
“Many persons are already doing as much as they’ll to lower your expenses on energy bills but there are hidden tricks that individuals can take themselves that don’t affect their comfort.
“We’ve found people can save £112 a yr just by making one change to their combination boiler to make it more efficient – a much greater saving than many better-known energy-saving suggestions.

“To assist as many individuals as possible lower your expenses and reduce carbon emissions, we now have designed a tool to guide anyone through this step-by-step.”
The Energy Price Guarantee is a Government-mandated cap on the unit price that households may be charged for energy, with typical annual bills rising this month to £2,500.
Nesta worked with Salford University to check how much gas is saved by lowering flow temperatures in a real-world environment.
These showed that reducing flow temperature from 80C to 60C can save nine percent of total gas use, or £112 for a median home.
A Nesta survey found that two-thirds of individuals (67 percent) said they’d wear warm clothes as an alternative of turning on the heating
Greater than half said they’d keep the heating on for fewer hours to scale back their bills while 57 percent said they’d lower the thermostat.
Rocio Concha, Which? Director of Policy and Advocacy, said: “We’re supportive of Nesta’s recent tool, which shows how reducing the flow temperature on combi boilers might help consumers shave money off their heating bills, without compromising on the temperature they heat their home to.
“We’re also calling on the Government to turbo boost the insulation of homes to assist consumers save energy and reduce their bills.
“It is usually vital that energy corporations do all they’ll to support their customers through this extraordinary cost of living crisis.”
