An air source heat pump is an energy-efficient, low-carbon heating system that extracts heat from the outside air and transfers it into your home to provide heating and hot water. Even during cold Essex winters, it can still generate heat – working like a fridge in reverse.
Air source heat pumps are up to 4 times more efficient than traditional gas boilers, helping homeowners in Essex reduce energy bills and lower their carbon footprint. They’re ideal for well-insulated homes and can be used with radiators or underfloor heating.


Not every property is suitable for an air source heat pump — but many homes across Essex are already perfectly positioned to switch to renewable heating.
At Clean Therm, we believe in honest, expert advice. We only recommend and install air source heat pumps in homes that are truly suitable — so you get real savings, long-term performance, and peace of mind.
Here’s a quick checklist to help you decide if your property is a good fit:
✅ Your home is well insulated (loft and cavity walls ideally filled)
✅ You have double glazing throughout
✅ You use radiators or underfloor heating
✅ You want to reduce your heating bills long-term
✅ Your current system runs on gas, oil, or electric
✅ You’re located in Essex or the surrounding areas
✅ You’re interested in the £7,500 Boiler Upgrade Scheme (BUS) grant
