Heat Pump Installers in Llandeilo

Thermal Earth is the closest specialist heat pump installer to Llandeilo, based just 10 minutes away at our headquarters in Ammanford. We have been installing ground source and air source heat pumps across the Towy Valley since 2006.

The Llandeilo area is ideal for heat pumps. The beautiful Towy Valley and surrounding countryside is predominantly off the gas grid, with many properties relying on expensive oil or LPG. A heat pump can reduce your heating bills by 40–70% while providing consistent, efficient warmth. The fertile valley floor also offers excellent conditions for ground source installations.

With over 3,500 installations completed, we bring unmatched local experience. We install MasterTherm heat pumps backed by our Comfort Care aftercare and remote monitoring. The £7,500 BUS grant is available to all homeowners.

Frequently Asked Questions

How much does a heat pump cost in the Llandeilo area?

Air source installations typically cost £8,000 to £18,000, and ground source systems £18,000 to £45,000 before the grant. The £7,500 BUS grant brings many air source systems to under £10,000. The Towy Valley’s good ground conditions make ground source a particularly efficient choice for larger properties.

Is the Towy Valley good for ground source heat pumps?

Excellent. The Towy Valley’s alluvial soils and underlying sandstone provide very good thermal conductivity for boreholes. The relatively flat valley floor also makes horizontal trench systems a viable option for properties with larger gardens. Our drilling team has extensive local experience and can advise on the best approach for your site.

Can a heat pump replace my oil boiler?

Yes — this is the most common installation we carry out in the Llandeilo area. A heat pump connects to your existing heating circuit and replaces the oil boiler entirely. You eliminate oil deliveries and tank maintenance. Most customers see significant annual savings on heating costs.

Can you install a heat pump in an older stone property?

Absolutely. The Llandeilo area has many beautiful stone-built farmhouses and period properties, and we have installed heat pumps in many of them. We carry out a thorough heat loss survey and design the system to match your property’s specific characteristics, accounting for wall thickness, insulation, and window types.

What grants are available near Llandeilo?

The £7,500 Boiler Upgrade Scheme is available to all homeowners. The Welsh Government’s Nest Scheme and Green Homes Wales offer additional support. We handle all grant paperwork as part of our service.

How long does installation take?

Air source installations typically take 2–3 days. Ground source systems take 3–5 days for indoor works plus 1–3 days for drilling. Being based nearby in Ammanford means our team can be on-site quickly and we can respond fast if any follow-up is needed.
