"Boiler flow temperature refers to the temperature your boiler heats water to before sending it to your radiators.
John Small, home energy expert and owner of Ty Eco, explains: “Boilers are typically set to a flow temperature of 75°C to 80°C, but this could be making your system less efficient and driving up your energy bills unnecessarily.”
When your boiler’s flow temperature is too high, it works harder than it needs to, wasting energy and money. Lowering the flow temperature can make your boiler more efficient, especially during milder weather, whilst keeping your house warm.
Finding the right boiler flow temperature depends on your home’s insulation and the time of year.
John Small recommends a tailored approach: “For older homes, aim for around 55°C in warmer months and closer to 60°C in the winter. For modern, well-insulated homes, you can go as low as 45°C during spring and summer, increasing to between 50°C and 55°C in winter.”"
