Can a heat pump replace my gas boiler completely?

Yes. A properly designed and installed air source heat pump provides all the space heating and hot water your home needs. It fully replaces a gas boiler.

How it works:

  • Space heating — the heat pump heats water that circulates through your radiators or underfloor heating, just like a boiler
  • Hot water — a dedicated hot water cylinder (usually 200–300 litres) stores hot water for taps and showers. This replaces a combi boiler’s on-demand approach with stored hot water that is ready when you need it
  • Controls — modern heat pumps have smart controls that learn your heating patterns and optimise efficiency

What customers tell us:

  • The warmth is more consistent and even compared to a boiler that cycles on and off
  • Rooms stay at a more stable temperature throughout the day
  • Hot water is plentiful, especially with a properly sized cylinder

Important considerations:

  • Your home’s insulation matters. A well-insulated home gets the best results.
  • Some radiators may need upgrading to work efficiently at lower flow temperatures
  • A heat-loss assessment is essential to size the system correctly

We design every system individually for each home to ensure it delivers the comfort and performance you expect.
