LG launches new Therma V Monobloc’s heat pump

LG has launched the latest version of its sector leading Therma V Monobloc air to water heat pump – the Therma V R32 Monobloc ‘S’.

LG has added a new Therma V Monobloc heat pump to the family.

As with the original Monobloc, this new model combines the indoor and outdoor features in one module. It’s also connected by water-only piping, eliminating the need for refrigerant piping.

Hydronic components such as 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’ works well at low ambient temperatures whilst lowering its carbon emissions even more with the use of R32. 

The innovative 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 original LG Therma V Monobloc has already had success in the UK marketplace as heat pump sales in 2021 trebled over sales in the previous year.  

‘S’ for ‘silence’ – an even quieter version 

The new Monobloc ‘S’ is equipped with a new advanced remote controller which supports several functions. It comes with a premium design 4.3-inch colour LCD monitor, user-friendly interface that uses simple graphics, 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.  

The original version was extremely quiet, but this new ‘S’ version is even quieter and up to 9kW units can be installed at a minimum of 4 metres away, and up to 16kW units – up to 5 metres 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 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 features LG’s revolutionary 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 a simple structure that offers lower noise and vibration, less weight and superior reliability. 

Major new interest from housebuilders and social housing providers 

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 backup heater. 

The unit comes with a seasonal coefficient of performance 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 of heating projects, said: “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.”
