What is an air source heat pump?


Air source heat pumps work by absorbing heat from the outside air. This heat is then used to heat radiators, underfloor heating systems or hot water in your home.

Working differently from a ground source heat pump, an air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside.

Air source heat pumps can get heat from the air even when the temperature is as low as -15° C, making it an ideal energy source all year round.

Heat pumps have some impact on the environment as they need electricity to run, but the heat they extract from the ground, air, or water is constantly being renewed naturally.

the benefits....

  • It could lower your bills, especially if you are replacing conventional electric heating
  • Minimal maintenance needed
  • It could lower home carbon emissions (depending on which fuel you are replacing)
  • It could provide you with income through the government’s Renewable Heat Incentive (RHI)
  • It can heat your home as well as your water
  • No requirement for fuel deliveries

is an air source heat pump right for you?

In a word yes, it is very important you service your existing heat pump, although many companies do not promote this. We are experienced in servicing these units so please contact us to find out more. 

You will need to find a suitable location outside your home for the unit. These can be fitted to a wall or placed on the ground. It will need to have plenty of space around it to get a good flow of air. A wall which gets sunlight is ideal.

Air source heat pumps work at their best when producing heat at a lower temperature than your traditional boiler, therefore it’s essential that your home is well insulated and draught-proofed for the heating system to be as effective as possible. 

If the system is replacing an electricity or coal heating system it will become cost neutral and start to pay for itself  quicker. This would take longer to achieve should the system be replacing a mains gas system so this should be a consideration.

Air source heat pumps generally perform better with underfloor heating systems or warm air heating than they do with radiator-based systems because of the lower water temperatures required.

Combining the installation with other building work can reduce the cost of installing the system.
