About air source heat pumps
Air source heat pumps are a space-saving and economical way to heat your hot water. Modern units are quiet and have high efficiencies of up to 450%. Air source heat pumps extract heat from the outside air, this is passed through a heat exchanger which boils the refrigerant gas. This also means they can generate heat even when the air temperature is as cool as – 15°C.

The benefits of air source heat pumps
- Lower fuel bills, especially if you are replacing conventional electric heating.
- Possible government grant available.
- Lower home carbon emissions.
- There are no fuel deliveries needed.
- It can heat your home as well as your water.
- There is minimal maintenance required.
- Can be easier to install than a ground source heat pump.
How do air source heat pumps work?
Air is drawn through the heat exchanger by the fan, the air heats the refrigerant, which in turn then heats the water for heating and not water. There are two main types of ASH: air-to-water and air-to-air. Choosing an air-to-water or an air-to-air system will determine the type of heat distribution system you need.

Costs
Installing a typical system costs around £9,000 to £15,000. Running costs will vary depending on a number of factors including the size of your home, how well insulated it is and what room temperatures you are aiming to achieve.
Savings
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 radiators sized for the application. 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 are likely to save money on your fuel bills (depending on the type of heating you are replacing).
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.
Water heating. If the heat pump is providing hot water then this could limit the overall efficiency. You may want to consider solar water heating to provide hot water in the summer and help keep your heat pump efficiency up.
Using 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.
Maintenance
Heat pump systems typically come with a warranty of two to three years. Workmanship warranties for heat pumps can last for up to 7 years, for example, through QANW (Quality Assured National Warranties).
Many manufacturers also offer options for warranty extensions for a fee.
With regular scheduled maintenance, you can expect an ASHP to operate for 20 years or more.
Every year, you should check that the air inlet grill and evaporator are free from leaves or other debris. Remove any plants that start to grow near the heat pump. You may also be advised by your installer to check the central heating pressure gauge in your house from time to time. If so, you should be shown how to do this.
Ask your installer for written details of any other maintenance checks you should undertake to ensure everything is working properly. Consult with your supplier for exact maintenance requirements before you commit to installing a heat pump.
A professional should service the heat pump every year.
Anti-freeze can be used to prevent the heat pump from freezing in cold winter weather.
Levels of anti-freeze and its concentration are some of the things that a professional installer will check when they come to service your heat pump. Though unusual for a domestic installation, some heat pumps have external refrigeration pipes, and these will need to be serviced annually by a refrigeration engineer.
