Air Source Heat Pumps

Air Source Heat Pumps

Air Source heat pumps provide an alternative, low cost solution for space heating and hot water, working in temperatures below -20 degrees Celsius. They extract heat from the outside air and can work efficiently all year round. Residential heating systems are most effective when used at lower temperature applications such as underfloor heating but they can be used with radiators in a well insulated home.

How does it work?

Heat from the air is absorbed into a refrigerant liquid via an evaporator. This causes the liquid to evaporate into a gas. The gas is then compressed, rising its temperature and its pressure. The hot compressed gas is then fed into a condenser heat exchanger where latent heat is then absorbed by the water in the space heating system. The refrigerant condenses back into a liquid when it passes through an expansion valve to start the process again.

There are two main types of air source heat pumps:

  • Air to water systems
  • Air to air systems

An air to water system distributes heat via the houses central heating system. Heat pumps work much more efficiently at a low temperature than a standard boiler system would. This makes them more suitable for under floor heating systems or larger radiators which give out heat at lower temperatures over longer periods of time.

An air to air system produces warm air which is circulated by fans to heat up your home. The downside is that they are unlikely to provide you with hot water as well.

Air Source Heat Pump Costs

Air source heat pumps produce more energy as heat than what they use as electricity, so their efficiency is more than 100%. To install a typical system can cost a home owner around £4,000 to £10,000. Replacing an existing system (electric) could potentially save you £610 a year and 5,570kg of CO² a year! Air source Heat pumps will be eligible for the RHI (Renewable Heat Incentive) on its release.
