The original LG Therma V Monobloc has already seen enormous success in the UK marketplace as heat pump sales in 2021 trebled over sales in the previous year. But this new ‘S’ version is set to make unparalleled sales figures in 2022, says LG, as more and more housebuilders and developers, local authorities, and social housing providers move to use renewable options in their newbuild homes and begin the process of replacing older and inefficient gas boilers with an option that futureproofs their existing homes in the years ahead.

As with the original Monobloc, this new model combines the indoor and outdoor features in one module. It’s also connected by only water piping, eliminating the need for refrigerant piping, making this heat pump an installer’s dream when it comes to ease of installation.

Hydronic components like the improved plate heat exchanger, the expansion tank, water pump, flow sensor, pressure sensor, air vent valve and safety valve are all built in – inside the outdoor unit – pre-installed and ready to run. And the R32 Monobloc ‘S’ provides strong heating performance especially at low ambient temperatures while lowering its carbon emissions even more with the use of R32.

The design and technology in this new unit sees built in water flow and pressure sensors to monitor the water circuit in real time, advanced water pump control, enhanced second circuit logic, energy monitoring of estimated power consumption via the remote controller, MODBUS connectivity without Gateway if required, and advanced control for the domestic hot water recirculation pump.

The new Monobloc ‘S’ is equipped with a new advanced remote controller which supports a number of functions. It comes with a premium design 4.3" colour LCD monitor, user friendly interface that uses simple graphic, icon, and text controls, easy schedule and installer settings, and energy monitoring without meter interface to provide estimated power consumption figures. It is possible to monitor not only the temperature of the water circuit but also the flow rate and the pressure. This information provides installers with more reliable information for installation and maintenance.

This new ‘S’ version is even quieter and up to 9kW units can be installed at the minimum of 4m away, and up to 16kW units up to 5m away from neighbouring houses, complying with international noise regulations. And through the use of LG’s ThinQ technology can monitor and control compatible LG products remotely so owners can set the temperature and regulate the use of their Therma V anytime, anywhere. ThinQ technology also works with voice activation with Google Homes.

The all-in-one concept and reduced weight of the unit makes for easier and quicker installations. The new version requires lower amounts of refrigerant compared to the existing model – 16.7% less in fact – reducing emissions and lessening its environmental impact still further. The new version also features LG’s R1 Compressor technology which offers advanced efficiency, reliability, and operational range, due in part to the enhanced tilting motion of the scroll. It offers enhanced operational range – up to 135Hz, a shaft-through structure and support at both ends of the shaft which ensures higher durability and offers bottom compression, and simple structure that offers lower noise and vibration, less weight, and superior reliability.

Within the outdoor unit the new version of the LG Monobloc offers a new compressor noise shield, a new Black Fin coated heat exchanger, a new water flow sensor and a new water pressure sensor. There is an option to include a 3kW or 6kW electric back up heater.

The unit comes with a Seasonal Coefficient of Performance (COP) of up to 4.67 (average climate/low temperature application) and a A+++ rating. The COP rises to 4.9 (outdoor air 7°C/leaving water temperature 35°C) and can deliver leaving water temperature of 65°C if required.

Peter Spurway, LG’s National Sales Manager – Heating Projects, said: “These are exciting times for heat pumps and for LG as we see hugely increased interest and sales of our established Therma V units. This launch of the new Monobloc ‘S’ gives us another massive lift as we can offer the leading monobloc unit on the market.

"We’re already seeing major interest in the new unit from housebuilders, social housing providers and self-builders – keen to find the best option for renewable heating projects up and down the country. They are seeing the latest advances incorporated into the new unit and with the restriction on the use of fossil fuelled heating in new build properties from 2025 are keen to begin working with the products that they will be using from that time onwards immediately.

"It is lazy specification to just keep on hanging combi gas boilers on walls of new homes now. It’s important that in a world that requires renewables as a matter of urgency, housebuilders begin to incorporate future proofing to their homes and deliver the energy efficiency and emission reducing technology that is proven across Europe here in the UK today.”
