Millions of UK households are being urged to stop being 'ignorant' about a simple boiler setting that could slash energy bills by hundreds of pounds annually. Heating experts have revealed that adjusting your boiler's flow temperature represents one of the easiest ways to reduce gas consumption without compromising home comfort.
The Secret Setting You're Probably Overlooking
Most modern combi boilers come with a default flow temperature setting that's often higher than necessary, typically around 75-80°C. However, experts from Nesta and the Heating and Hotwater Industry Council (HHIC) confirm that reducing this to 60°C for heating and 55°C for hot water can yield significant savings.
Substantial Savings for Typical Homes
According to detailed analysis, the average household could save approximately £112 per year simply by making this adjustment. For those in larger detached properties, the savings could reach an impressive £220 annually. With energy prices remaining stubbornly high, these adjustments represent meaningful financial relief for families across the country.
Why This Simple Change Works
Lowering the flow temperature doesn't mean your home will be colder—it simply means your boiler operates more efficiently. Rather than producing short bursts of intense heat, your system will run for longer periods at lower temperatures, maintaining consistent warmth while using less gas.
How to Adjust Your Boiler Settings
For combi boiler owners:
- Locate the central heating flow temperature dial on your boiler
- Gradually reduce the temperature to 60°C
- Allow 24 hours to assess comfort levels
- Adjust slightly if needed, but avoid returning to original high settings
Stewart Clements of HHIC emphasises that most households 'won't notice the difference' in comfort, while energy expert Paula Haugh from Nesta describes it as 'the single most effective thing you can do to save money on your gas bill.'
A Nationwide Saving Opportunity
If just half of UK households with combi boilers implemented this change, the collective savings could reach over £1 billion annually. Beyond the financial benefits, reducing gas consumption also contributes to lower carbon emissions, making it an environmentally conscious choice.
The message from energy experts is clear: don't overlook this simple adjustment that could put hundreds of pounds back in your pocket while helping the environment.
