An air source heat pump (ASHP) is renewable energy technology that extracts heat from the air outside and uses it to provide heating and hot water in your home.

When the ASHP is in heating mode, the outdoor unit extracts heat from the outside air, which is absorbed by the refrigerant fluid circulating in the heat pump unit. The compressor then raises the temperature of the refrigerant fluid, which is then transferred to the indoor unit. The indoor unit then releases the heat into the indoor air or water, which is circulated throughout the building.

ASHPs are highly efficient, as they use electricity to move heat rather than creating it directly. The amount of heat that can be extracted from the air depends on the outdoor temperature, so they are most efficient in mild to moderate climates. They can also be used in reverse for cooling in the summer, making them a versatile year-round heating and cooling solution.

Air source heat pumps are a clean and renewable energy technology that can help to reduce carbon emissions and provide an efficient and cost-effective heating and cooling solution for homes and buildings. ASHPs are regarded as ‘fit and forget technology’ due to how little maintenance they require to run; their positive environmental impact also makes those considering installation eligible to obtain a government grant (Boiler Upgrade Scheme BUS) which covers part of the cost of replacing fossil fuel heating systems with ASHPS.

Another benefit of Air Source Heat Pumps is that they can be powered by Solar Panels – meaning that in some cases the electricity generated can allow you to run your Air Source Heat Pump for free.
