Air Source Heat Pump
What does an Air Source Heat Pump look like?
Air source heat pumps are similar in appearance to the air conditioning units commonly seen on office buildings or in warmer climates. The size of the unit required will depend on several factors, including your home’s heating demand, the size of the property, and how well it is insulated.
A typical unit may measure around one metre high and one metre wide, with a depth of approximately half a metre. However, sizes can vary depending on the manufacturer and model.
How does an Air Source Heat Pump work?
An air source heat pump works by extracting heat from the outside air and transferring it into your home. Using a refrigerant system that includes a compressor and condenser, the heat is absorbed from the air and moved through the system.
It is then raised to the required temperature to provide heating for your home, producing warm air or hot water for radiators, underfloor heating, or domestic use.
What We Offer / Installation & Servicing
Servicing
Annual servicing is recommended for all air source heat pumps and is typically required to maintain the manufacturer’s warranty. Regular servicing ensures the system continues to operate efficiently, safely, and reliably.
In addition, schemes such as the Renewable Heat Incentive (RHI) require your system to be properly maintained and operating effectively. Routine servicing helps ensure your heat pump performs at its best while supporting long-term efficiency and reliability.
We can also service systems we didn’t install!
Installation
An air source heat pump is typically installed outside the property in a location with good airflow to ensure efficient operation. The unit then transfers heat into the home via pipework connected to an indoor system, which is usually located in a utility room, garage or designated plant room. From there, the heated water is distributed to either your central heating system, such as radiators or underfloor heating; or the storage cylinder for hot water.
MCS Accredited Installers
We are MCS accredited air source heat pump installers, meaning our systems meet the strict standards set by the Microgeneration Certification Scheme. This ensures every installation is completed to a high quality and allows our customers to access government incentives such as the Boiler Upgrade Scheme.
