If you're looking for a trusted, experienced heat pump installer near you, Russell Heating Ltd is your local specialist. With more than 20 years' hands-on experience, our qualified team of renewable heating engineers designs, installs, services and repairs air source heat pumps for homes and businesses across Bedfordshire, Hertfordshire and Cambridgeshire. We focus on practical, energy-smart solutions with advice tailored to your property, your needs and your budget — so you know exactly what you're getting and why.
Government grants available — you could save up to £7,500 off the cost of your air source heat pump installation through the Boiler Upgrade Scheme (BUS). We handle the full heat pump grant application on your behalf, and all heat pump installations qualify for 0% VAT. The scheme is open until 2028.

An air source heat pump extracts natural warmth from outside air and transfers it into your home, even when temperatures drop below zero. It can power underfloor heating, radiators, hot water cylinders and warm air convectors — providing heating and hot water from a single, low-carbon system. While it requires electricity to run, a correctly designed heat pump system typically produces three to four units of heat for every unit of electricity used, significantly reducing your energy bills and carbon footprint compared to a traditional gas or oil boiler.

Our air source heat pump services include:

Air source heat pump installation — new builds, retrofits, extensions and boiler replacements
Heat pump servicing — all makes and models, annual maintenance plans
Heat pump repair and fault diagnosis — compressor, PCB, flow switch and refrigerant issues
Heat loss calculation and full system design
Hybrid heating systems — heat pump combined with an existing gas or oil boiler
Underfloor heating installation and radiator upgrades sized for heat pump flow temperatures
Unvented hot water cylinder installation and replacement
Replace gas boiler with heat pump — full changeover service
Replace oil boiler with heat pump — including oil tank decommissioning
Commercial heat pump installation — schools, care homes, offices and industrial premises
Boiler Upgrade Scheme grant applications — handled on your behalf

Every installation starts with a full property survey and heat loss calculation, so your heat pump is correctly sized and specified — not guessed at. We design systems to run at the lowest possible flow temperatures, maximising efficiency and keeping your running costs down. We handle everything from initial consultation through to commissioning, system handover and aftercare.
