LG’s heating product portfolio comprises a wide range of highly energy efficient renewable energy systems, providing the right heating solution for any application and requirement.

THERMA V is LG’s Air to Water Heat Pump system, especially designed for new housing and renovation. The heat pump range can supply heating through various heat emitter types (under floor heating / radiators) while also providing all your domestic hot water requirements. LG heating products provide a greener and more energy efficient heating solution through continuous research and development of green energy technologies such as R32 refrigerant AWHP and R1 scroll compressor.

Unitherm is the exclusive supplier of LG Heat Pump products in Ireland.

The THERMA V R32 Monobloc S is the 2nd generation of LG's R32 Monobloc series, released in 2021. As implied by “silence” and “supreme," it boasts reduced noise level and best performance in the THERMA V Series. Combining the indoor and outdoor as one module, it's also connected by only water piping eliminating the need for refrigerant piping. Furthermore, hydronic components like the plate heat exchanger, expansion tank, water pump, flow sensor, pressure sensor, air vent valve, and safety valve are conveniently situated inside the unit. The R32 Monobloc S provides excellent heating performance, especially at low ambient temperature while it lowering its carbon emissions with R32.

With innovation and safety in mind, the LG Therma V Hydrosplit separates the Indoor unit (IDU) and outdoor unit (ODU), connecting them through water pipes.

The unit’s heat exchanger is located within the ODU, reducing the risk of indoor refrigerant leakage. Quick and easy installation is made possible by the IDU’s built-in hydronic components such as water pump, expansion tank, and air vent as well as the fact that the electric wiring can be done in the same space as the IDU.
