Households across the UK are being urged to make a simple, free change to their boiler settings that could dramatically cut their energy costs. This quick fix requires no technical skill and could put over £100 back in your pocket every year.
According to energy expert Ben Gallizzi from Uswitch, adjusting your boiler's 'flow temperature' is one of the most effective ways to reduce gas consumption without sacrificing comfort. This setting controls how hot the water is when it leaves your boiler to go to your radiators.
How Does Lowering The Flow Temperature Save You Money?
Many modern combi boilers are installed with a default flow temperature that is often higher than necessary. By reducing this temperature, your boiler doesn't have to work as hard or burn as much gas to heat your home. It's a more efficient way to operate, especially with condensing boilers which are designed to recover more heat when running at lower temperatures.
This adjustment is different from turning down your thermostat. You're not lowering the overall temperature of your home; you're simply making your heating system work more efficiently.
The Potential Savings Are Significant
The exact amount you can save depends on your current settings and household circumstances, but the figures are compelling. Experts suggest that a typical household could save around £112 per year on their gas bill by implementing this change. For some, the savings could be even greater.
This advice comes at a crucial time when many families are still feeling the pressure from high energy costs, despite recent falls in the price cap.
How To Adjust Your Boiler Settings
Making this change is surprisingly simple. Here's what you need to do:
- Locate the controls on your combi boiler.
- Find the dial or digital setting for central heating flow temperature.
- Adjust this setting to 60°C for optimal efficiency.
- Your radiators may take slightly longer to heat up, but they will still reach a comfortable temperature.
It's important to note that this advice applies specifically to homes with condensing combi boilers. If you have a different system, such as one with a hot water cylinder, you should consult a heating engineer before making changes.
This simple tweak represents one of the easiest ways to reduce your energy bills immediately. As Gallizzi notes, it's about working smarter with the heating system you already have, rather than making expensive upgrades or sacrificing comfort.
