What is an air source heat pump?

Air Source Heat Pumps absorb heat from the outside air to heat your home and hot water. They are a greener, cleaner alternative to gas and oil, and can extract heat from air temperatures as low as -15°C!

Self-builders everywhere are falling in love with Air Source Heat Pumps. Your dream home deserves a heating system that fits your lifestyle. Studies have shown that Air Source Heat Pump and underfloor heating work excellently together in order to achieve cost-effective, environmentally-friendly and cosy warmth day after day.

How do they produce heat?

An Air Source Heat Pump uses energy absorbed from the air and transfers it to the water based heating system via a vapour/compression cycle.

The process uses a refrigerant gas R32/R290 which has a low boiling point. When the R32/R290 gas is exposed to external air it heats up and compresses causing the temperature to increase. It then changes from a gas to a liquid before passing through a heat exchanger transferring heat to the heating system. As the heat is transferred to the heat exchanger the liquid changes back to a gas and the cycle is repeated.

Benefits of an Air Source Heat Pump

You Control Your Heat Demand

By utilising ASHP integrated technology, you can smartly manage your heat demands to ensure optimum efficiency and satisfaction.

Quality of Heat

As opposed to the ‘blasts’ of heat provided by traditional heating systems and fuels such as gas and oil, ASHPs operates a ‘slow and steady’ kind of heat provision, offering high-grade consistent heat at lower temperatures. This is boosted further by better levels of heat retention in newer dwellings.

Saving on Energy Bills

In new homes, your Air Source Heat Pump operates between 25 – 30% more cost-effective than traditional heating alternatives.

Air Source Heat Pump FAQs

What servicing is required and how often does an air source heat pump need serviced?

Accordion icon
An air source heat pump should be professionally serviced once a year to check refrigerant levels, electrical connections, filters, and general operation. Between services, you should keep the outdoor unit clean and clear of debris, and occasionally check filters and drains. Regular annual servicing keeps it efficient and maintains the warranty.

What is the difference between a mono-bloc and a split unit air source heat pump?

Accordion icon
A monobloc air source heat pump has all its components — including the compressor and heat exchanger — contained in a single outdoor unit. Water from your heating system runs directly to and from this unit. A split system separates the components: the compressor is outside, while the heat exchanger and control systems are inside. Split units generally perform better in colder weather and can be quieter indoors, but they require refrigerant pipework and professional installation by a qualified refrigerant engineer. Monobloc systems are simpler to install and maintain but may lose a bit more heat over longer water pipe runs.

Location of an Air Source Heat Pump?

Accordion icon
An air source heat pump is usually installed outside the building, in a spot with good airflow and easy access for servicing. It should be placed on a solid, level base close to the house to reduce pipe runs and heat loss. Ideally, it’s positioned away from windows and neighbouring properties to minimise noise, and clear of obstructions like walls or plants so air can flow freely around it.

Can I use underfloor and radiators with an air source heat pump?

Accordion icon
Air Source Heat Pumps can be used with underfloor and/ or radiators. The underfloor or radiators must be sized to run at a lower flow temperature usually 30 – 45 degrees, to main the efficiency of the ASHP.

Can Photo-voltaic solar panels be incorporated into my air source heat pump system?

Accordion icon
Yes, Photo-voltaic solar panels can work with an air source heat pump. The panels generate electricity to power the heat pump, lowering energy costs and making the system more efficient and sustainable.

Can solar thermal be incorporated into my Air Source Heat Pump system?

Accordion icon
Yes, solar thermal can be combined with an air source heat pump. The solar panels can preheat the water, reducing the heat pump’s workload and improving overall efficiency, especially for hot water production.

Is an Air Source Heat Pump noisy?

Accordion icon
An air source heat pump makes some noise from its fan and compressor, but modern units are generally quiet—typically similar to a fridge or a low-speed fan. Proper placement and installation help keep noise to a minimum.

Are Air Source Heat Pumps suitable for older dwellings?

Accordion icon
Air source heat pumps can work in older homes, but they are most efficient in well-insulated properties. Older dwellings often need upgraded insulation, double glazing, and draught-proofing to maintain comfortable temperatures and make the system cost-effective.
