What is an air source heat pump?
An air source heat pump (ASHP) extracts heat from outdoor air and transfers it into your home via radiators, underfloor heating, or a hot water cylinder — even when temperatures drop as low as -15°C. It works like a refrigerator in reverse: absorbing heat energy from the air outside and compressing it to a higher, usable temperature inside.
Because ASHPs move heat rather than generate it, they typically produce 3 units of heat energy for every 1 unit of electricity used — making them around 300% efficient. Compare that to an A-rated gas boiler at 85–92%, and the difference is clear.

How do air source heat pumps work?
Evaporation
The heat pump draws in outside air across a refrigerant-filled heat exchanger. The refrigerant absorbs the heat and evaporates into a low-pressure gas.
Compression
The gas passes through a compressor, raising its pressure and temperature significantly.
Condensation
The hot gas moves through a second heat exchanger, transferring its heat into your home’s water circuit — warming radiators, underfloor heating, or your hot water cylinder.
Expansion
The refrigerant cools, returns to liquid form, and passes through an expansion valve — ready to start the cycle again.
Why homeowners in Wrexham & North Wales are switching to heat pumps
Up to £7,500 in Government Funding
Air source heat pumps qualify for the Boiler Upgrade Scheme, which provides £7,500 off the cost of supply and installation. Rawson Solar manages the grant application on your behalf.
NIBE Pro Approved Installation
As an approved NIBE Pro installer, we’re trained and accredited directly by NIBE to install their market-leading heat pump systems to the highest standard — giving you full manufacturer warranty protection.
3–4x More Efficient Than a Gas Boiler
ASHPs typically operate at 300% efficiency or above. A gas boiler, even an A-rated one, maxes out at around 92%. Over time, that difference shows up clearly on your energy bills.
Lower Carbon Footprint
Switching from a gas or oil boiler to a heat pump significantly reduces your home’s carbon emissions — especially as the UK electricity grid continues to get greener.
Improved EPC Rating
Installing an ASHP can improve your home’s Energy Performance Certificate rating, which matters if you’re looking to sell or remortgage.
Pairs Perfectly with Solar Panels
Already have solar? Your ASHP can run primarily off your own generated electricity, cutting running costs even further. Rawson Solar can design a fully integrated system.
Save up to £7,500 with the Boiler Upgrade Scheme
The Boiler Upgrade Scheme (BUS) is a government grant that provides homeowners in England and Wales with £7,500 towards the cost of an air source heat pump. The grant is deducted directly from your installation quote — you never handle the funding yourself.
Rawson Solar are MCS accredited, which is a prerequisite for any installer applying for BUS grants on behalf of customers. We handle the paperwork, submission, and follow-up so you don’t have to.
