...and our solution.
After assessing the property in Tonbridge and understanding the client’s needs, we designed a system centred around the LG 12kW Air Source Heat Pump (ASHP), known for its high efficiency and reliability. Paired with the 200L UniTherm pre-plumbed cylinder and its built-in 50L buffer tank, this setup offered a seamless solution for both underfloor heating and radiators.
Why we chose this system

LG 12kW ASHP
This unit is highly efficient, capable of extracting heat from the air even in colder temperatures, making it perfect for year-round heating. It’s ideal for larger homes or properties with higher heating demands, like this one, which has a mix of underfloor heating and radiators.

200L UniTherm Pre-Plumbed Cylinder
This cylinder stores hot water efficiently, ensuring there’s always a steady supply for both the underfloor heating system and the radiators. The built-in 50L buffer tank helps prevent short cycling, improving the overall efficiency of the system.

Versatility for UFH and Radiators
The system can manage the lower temperature demands of underfloor heating while also providing enough heat for the higher temperature requirements of the radiators. This ensures the whole house stays warm, whether it’s the heated ground floor with or upper floors using radiators.
The installation process
The installation was completed over a few days, ensuring minimal disruption to the homeowner. We carefully integrated the Air Source Heat Pump into the existing setup and configured it to efficiently run both the under floor heating and radiators. The pre-plumbed cylinder helped streamline the installation process, reducing installation time and ensuring that the system was set up correctly with the buffer tank in place for optimum performance.
Throughout the installation, we made sure to keep the client informed about how the system works, including how to adjust settings for different heating needs and how to maximise energy efficiency.


The results
The new system is now providing efficient, reliable heating throughout the home. The underfloor heating offers even, comfortable warmth on the ground floor, while the radiators quickly warm up the upper floors, all managed seamlessly by the LG 12kW ASHP and the UniTherm cylinder. The client has noticed a significant improvement in heating efficiency compared to their old system, and they are already enjoying the benefits of lower energy bills.
