Did you know that lowering your boiler’s flow temperature to 55 degrees Celsius can significantly reduce your energy consumption and help lower your heating bills? This simple adjustment is especially effective for combi boilers and modern condensing systems, which operate more efficiently at lower temperatures.

Why 55°C Makes a Difference

Most boilers are set to a default flow temperature of around 70°C. While this heats your home quickly, it prevents your boiler from operating in condensing mode, where it recycles heat from exhaust gases. By reducing the flow temperature to 55°C, your boiler can work more efficiently, saving up to 10% on your energy bills without compromising comfort.

The Role of Regular Boiler Servicing

Lowering your heating temperature is a great start, but regular boiler servicing is essential to ensure your system runs safely and efficiently. Whether you’re using an Ideal, Vaillant, or Worcester boiler, annual servicing helps:

  • Detect and prevent faults early

  • Improve energy efficiency

  • Extend the lifespan of your boiler

  • Maintain manufacturer warranties
