An air source heat pump is a type of renewable heating system that uses the heat from the outside air to heat and heat your home's water. It functions by transferring heat from the air to a refrigerant fluid once it has been absorbed. A distribution system then amplifies the heat before releasing it into your house or building.

Air source heat pumps use a refrigeration cycle to extract heat from the outdoor air. A refrigerant fluid that circulates inside the heat pump absorbs the heat. The fluid is then compressed, raising the temperature of the fluid. Your home's heating system or hot water tank receives heat from the heated refrigerant. The procedure is then repeated with the refrigerant that has been cooled returning to the outdoor unit.

Air source heat pumps can be used in conjunction with current heating systems. They can be integrated with underfloor heating systems, conventional boilers, and radiators. The heating system should be modified to function best with the heat pump, such as by using larger radiators or underfloor heating for lower temperature operation, in order to maximise efficiency.

In general, air source heat pumps require little maintenance. To make sure the system is running effectively, it is advised to have an annual check-up by a certified expert. It could be required to regularly clean or replace the air filters, as well as check the fluid levels. You can get advice on the precise upkeep needs for your air source heat pump from your chosen installer.

Air source heat pumps can last 15 to 20 years or longer with adequate maintenance. The quality of the installation, the frequency of maintenance, and the make and type of the heat pump itself all affect how long the system will last.
