Millions of UK households could be throwing away hundreds of pounds each year by overlooking a simple boiler setting that takes just minutes to adjust, according to a leading heating expert.
James Bowen, an experienced heating engineer, is urging homeowners to check their boiler's flow temperature in what he describes as "one of the easiest ways to make immediate savings" on escalating energy costs.
The Secret Setting Hiding in Plain Sight
"Most people don't realise their boilers are working much harder than necessary," Bowen explains. "By simply adjusting the flow temperature - the temperature at which water leaves your boiler to heat your radiators - households can achieve significant reductions in their gas consumption."
The recommended adjustment involves lowering the flow temperature from the typical factory setting of 75-80°C down to a more efficient 60°C for combi boilers, or 65-70°C for system boilers with hot water tanks.
Substantial Savings Without Sacrificing Comfort
Contrary to what many might expect, this adjustment doesn't mean living in a colder home. Bowen emphasises that radiators will still provide adequate warmth, they'll just take slightly longer to heat up initially.
"The beauty of this adjustment is that it maintains comfort while cutting costs," he says. "For every degree you lower your flow temperature, you're saving approximately 1% on your gas bill. For the average household, this could translate to £60-£100 in annual savings."
Environmental Impact Goes Beyond Your Wallet
The benefits extend far beyond personal finances. Bowen highlights that if just half of UK households made this simple change, the reduction in carbon emissions would be equivalent to taking hundreds of thousands of cars off the road.
"We're facing both a cost of living crisis and a climate crisis," Bowen states. "This is one of those rare solutions that addresses both issues simultaneously without requiring major investment or lifestyle changes."
How to Make the Change Today
Adjusting your boiler's flow temperature is surprisingly straightforward:
- Locate your boiler's digital display or dial controls
- Find the central heating flow temperature setting (usually marked with a radiator symbol)
- Gradually reduce the temperature to 60°C for combi boilers
- Wait 24 hours to assess comfort levels
- Make further small adjustments if needed
Bowen reassures homeowners: "This is completely safe and won't damage your boiler. If you're unsure, consult your boiler manual or contact a qualified engineer."
With energy prices remaining stubbornly high, this expert advice offers a glimmer of hope for households seeking practical ways to reduce their bills while contributing to environmental conservation.
