Heating engineer shares 'simple and effective' energy hack to cut bills fast

This past week, Brits were urged to check a boiler flow setting this winter, as many across the UK could be spending far more while energy bills are expected to rise again.
Many boilers are still set much higher by default, often between 70°C and 80°C, while most modern condensing combi boilers run efficiently at lower flow temperatures controlling water leaving the boiler.
Gordon Wallis, energy expert at Your NRG, advised lowering radiator flow temperature to around 55°C, noting it heats homes effectively with less energy while radiators take slightly longer to warm.
Adjusting flow temperature could reduce gas use without turning heating off, and households should also check hot water temperature setting to avoid unnecessary heat costs.
Social media and energy suppliers recently recommended lower flow temperatures, but owners of hot water tank systems or older boilers should consult a qualified engineer first; the change works best for combi boilers in well-insulated properties.
