Air Source Heat Pump Installation in Carmarthen
Air source heat pumps designed and installed across Carmarthen and Carmarthenshire. MCS-certified installs eligible for the \u00a37,500 Boiler Upgrade Scheme grant.
Independent, evidence-based surveys
An air source heat pump extracts heat from outside air and uses it to warm your Carmarthen home and hot water. Even in cold weather it delivers 3-4 units of heat for every 1 unit of electricity used.
We arrange design and installation of ASHPs across Carmarthen, from straightforward retrofits replacing an old gas or oil boiler through to complete new heating systems with low-temperature radiators or underfloor heating.
All installs are completed by our MCS-certified installer partners, so you qualify for the £7,500 Boiler Upgrade Scheme grant, cutting the upfront cost dramatically. We handle the grant application as part of the install.
