Is an air source heat pump the right option for me?

Whilst most homes are suitable for a heat pump, some updates such as improved insulation or radiator upgrades may be required to your property for the heat pump to work effectively. Our installers will never install a heat pump that won't keep your home comfortably warm.

To install a heat pump, you'll also need to meet all the requirements below:

  • you need to be a homeowner 
  • your home needs to have enough outside space (approx 2m x 1m) and not within 1m of boundary walls
  • your home needs enough space for a water tank
  • your home needs to have good insulation, such as cavity wall and loft insulation

Air source heat pump FAQs

There are many factors that contribute to whether you’ll be able to save money on your energy bills, such as:

  • your electricity tariff
  • the type of heat pump you install
  • the design of your central heating system
  • your location and its average air or ground temperatures throughout the year

Savings on your energy bill will also depend on the system you're replacing. According to Energy Saving Trust, if you're replacing an old (G-rated) gas boiler with an air source heat pump you could save up to £340(3).

Heat pumps work more efficiently when it’s warmer which means they’ll have to work a bit harder when it’s cold, just like a boiler. However, the heat pumps we can offer still work effectively at -25°C.

The heat pump that's installed is bespoke to your home. After speaking with a specialist and designing the right heat pump for you, it will take around 3-5 days to install. To read more about air source heat pump installations, visit our installation guide.

In some cases, we’ll recommend installing larger radiators. If you have old or single panel radiators, you may need to replace your radiators for double or triple panel radiators to increase the surface area. Radiator upgrades are important as they’ll improve the efficiency of your heat pump and reduce running costs.

You can expect the noise to be a similar volume to a fridge. As it gets colder outside, this noise will increase while it’s operating. However, you shouldn’t be able to hear the sound indoors.

All of our heat pumps come with a manufacturer's warranty of up to 7 years.
