Air Source Heat Pumps

Yes, air source heat pumps can save you up to £1,100 compared to traditional heating systems. Exactly how much you can save with an air source heat pump depends on its coefficient of performance (CoP).

The running costs of air source heat pumps range from £650 to £1150 a year and they largely depend on the system size and current gas prices. However, many more factors contribute to the running cost of air source heat pumps.

You can expect to pay anywhere between £1,500 and £18,000 for the cost of an air source heat pump. However, the price ultimately depends on what type of air source heat pump you’re looking to install. Air-to-water heat pumps tend to cost more than air-to-air heat pumps.

Air source heat pumps can still provide heating during the winter months in the UK, however, their efficiency may decrease due to the fact that they lose efficiency below 0°C as they rely on the outside air.

ASHP HEAT PUMP Coefficient of Performance, or COP, refers to the amount of energy produced by the heat pump compared to the amount of energy used to run it. The higher the COP, the more efficient the technology.

For example, an electric fire using 1kWh of electricity to generate 1kWh of heat would have a COP of 1 – making it 100% efficient as it uses the same amount of energy as it generates. An ASHP HEAT PUMP that uses 1kWh of electricity to generate 4kWh of heat would have a COP of 4 and is 400% efficient, extracting an additional 3kWh of heat from the Air to provide heating and hot water.

You can expect an air source heat pump to last for 20 years or more. Because they’re based on a relatively simple and reliable technology, heat pumps don’t need a lot of maintenance – although an annual service is recommended.

Yes. Air source heat pumps work effectively even when outside temperatures are -15°C, although they are a bit more energy efficient at warmer temperatures.

Air source heat pump systems use a hot water cylinder to heat water. Your home's water is heated and stored in a cylinder for when you need it.
The cylinder is insulated so once the water is heated it'll stay hot for several hours, so you should always have hot water for washing dishes and running a bath.
We'd recommend the hot water tank to meet your needs, so you'll always have enough hot water for your home.

You could mount an air source heat pump on a wall, if it's still easily accessible by an engineer. But for optimal performance and a reduced operational sound, we'd recommend it be installed at ground level.
