What we install and why it works: Air source heat pumps extract ambient heat from outside air and boost it to heat radiators, underfloor systems and domestic hot water. They’re ideal for well‑insulated semi‑detached and detached homes, new builds and many older properties after a suitability survey. We select high‑performance units, size the system to your home and ensure correct flow temperatures and buffer cylinders for reliable hot water and even heating.
Local knowledge, regulated workmanship: OneHeat Limited engineers are City & Guilds qualified and CHAS‑accredited, delivering installations and repairs with clear paperwork and safety standards. We guide customers through grant eligibility such as the Boiler Upgrade Scheme, provide running‑cost modelling so you can make an informed choice, and offer practical finance options.

Frequently Asked Questions
Many older homes can use ASHPs successfully, but suitability depends on insulation, radiator size and available outdoor space for the condenser. We carry out a measured survey and advise whether additional insulation, larger radiators or a buffer cylinder are needed to get the best performance.
