LG introduces 12kW, 14kW, and 16kW models to its Therma V R290 Monobloc S heat pump range for larger UK residential properties.
LG Electronics has expanded its Therma V R290 Monobloc S heat pump lineup, introducing higher-capacity 12kW, 14kW, and 16kW models aimed at larger UK residential units and light commercial retrofits.
The addition of these higher-output units allows heating installers to specify propane (R290) natural refrigerant systems for properties with larger heat loads. The R290 Monobloc S design integrates hydraulic components inside the outdoor unit, simplifying the installation process for plumbing and heating engineers without requiring F-gas qualification for the refrigerant circuit itself.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
For heating engineers and plumbing contractors buying through merchant networks, the expanded range provides a single-brand option when upgrading larger detached homes or older properties that previously required multiple smaller units or hybrid fossil-fuel setups. While higher-capacity R290 units command a premium initial purchase price compared to standard R32 split systems, the monobloc design reduces indoor footprint and installation complexity. Installers must account for R290 safety clearances due to propane's flammability, meaning outdoor placement must strictly comply with manufacturer setback distances from drains, windows, and property boundaries.
The extension aligns with growing UK demand for low-carbon heating solutions under current building regulations, offering higher flow temperatures suitable for standard radiator networks without requiring complete emitter overhauls in every retrofit scenario.
