When our clients moved from Worcestershire to the beautiful coastal village of Llansaint in Carmarthenshire, they found a characterful home that almost met every need. The only drawback was the outdated oil boiler tucked away in a small room off the kitchen – a space they hoped to convert into a much-needed utility room.
Looking for a way to make their home more practical, efficient, and sustainable, they decided to explore renewable heating options. Their goal: to replace the old oil system with a clean, modern air source heat pump installation that could work seamlessly alongside their existing solar panels.
Moving Away from Oil to Renewable Energy
Already benefiting from a 4kW solar array powering their immersion heater, the homeowners wanted to build on their renewable setup and say goodbye to oil for good. After researching the latest technology, they identified the LG Therma air source heat pump with R290 refrigerant as the ideal choice – combining powerful performance with excellent environmental credentials.
When comparing installers, Birds Hill stood out. Our detailed heat-loss calculations and in-depth knowledge of LG products gave the clients confidence that their project would be handled by a team that truly understood the technology and how to get the best results from it.
“Birds’ Hill’s heat-loss calculations were comprehensive, and their recommendations for upgrading certain radiators made perfect sense. The engineers fitted everything cheerfully and professionally, despite the size and weight of some of the new radiators.”
Careful Planning and Precision Installation
The air source heat pump system was installed between April and May 2025, including a new domestic hot water cylinder, several new radiators, and partial re-piping of the existing system.
Because the property had evolved over several decades – originally a two-room stone cottage with later extensions and varying levels of insulation – the heat-loss calculations were complex. Our engineers took a meticulous approach, ensuring each room would be evenly heated while maintaining efficiency.
The clients’ plan to repurpose the old boiler room into a utility space meant that every inch mattered. Pipework placement was carefully considered to maximise usable space without compromising access for servicing.
“The engineers were very careful about where they ran pipework to make the most of the space. They were always happy to explain their plans as they went along, which gave us complete confidence in the process.”
Comfort, Efficiency and Consistent Warmth
Now that the system has been running through the warmer months, the results speak for themselves.
“Hot water is plentiful and the house is warm first thing in the mornings. It’s a different kind of heat: even and comfortable.”
Since making the switch, the homeowners haven’t needed to order oil, and with their fixed electricity tariff and solar power offset, they can forecast their energy costs with much greater certainty. The next stage of their renewable journey will be the addition of battery storage to further increase efficiency.
A Reflection of Today’s Renewable Heating Trends
Air source heat pumps have become one of the most popular choices for homeowners looking to cut their carbon footprint and reduce energy bills. They’re efficient, environmentally friendly, and increasingly supported by Government incentives such as the Boiler Upgrade Scheme, which offers £7,500 towards replacing an old oil or gas boiler with an air source heat pump.
For this Carmarthenshire home, the system delivers everything the owners hoped for – low-maintenance operation, steady warmth, and reliable performance throughout the year.
“It’s as close to a ‘fit and forget’ system as you can get.”
