UK households can save £100 yearly by lowering boiler temperature to 60°C for better efficiency.

UK households are being advised to lower their boiler’s flow temperature from the default 75°C to 80°C down to 60°C to improve efficiency and cut heating costs. Experts say this simple adjustment allows modern combi boilers to operate in condensing mode, reducing gas consumption by up to 9% and saving an average of £100 annually, without affecting home warmth. The change is easy to make and can help reduce energy bills during winter.
