Savings from using a heat pump


Using a heat pump can deliver considerable cost savings when compared with other heating methods

eg Oil, gas, LPG, electric storage heaters etc.

Replacing storage heaters with a heat pump will give the greatest saving followed by LPG and oil

comparioson of heating costs


Heat pumps have an efficiency rating called a COP (coefficient of performance)

The higher the COP, the more efficient the heat pump is and the lower the running costs will be.

All of the heat pumps that we sell at HeatPumps4Homes are MCS approved, which means that their output and COP figures have been independently tested and certified.


How much you can save will depend on what system you use now, as well as what you are replacing it with. Your savings will be affected by:

  • Your heat distribution system
    If you have the opportunity, underfloor heating can be more efficient than radiators because the water doesn’t need to be so hot. If underfloor heating isn’t possible, use the largest radiators you can. Your installer should be able to advise on this.
  • Your fuel costs
    You will still have to pay fuel bills with a heat pump because it is powered by electricity, but you will save on the fuel you are replacing. If the fuel you are replacing is expensive you are more likely to make a saving.
  • Your old heating system
    If your old heating system was inefficient, you are more likely to see lower running costs with a new heat pump.
  • Old fuel type
    Replacing oil boilers, LPG or storage heaters will give the best savings. but good savings can also be made when replacing mains gas systems.
  • Water heating
    If the heat pump is providing hot water then this could limit the overall efficiency. You might want to consider solar water heating to provide hot water in the summer and help keep your heat pump efficiency up.
  • Using the controls
    Learn how to control the system so you can get the most out of it. You will probably need to set the heating to come on for longer hours, but you might be able to set the thermostat lower and still feel comfortable. Your installer should explain to you how to control the system so you can use it most effectively.

These are the savings you might make every year when replacing an existing heating system in an average four-bedroom detached home with an average ASHP (air source heat pump) installation:
