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.

The THERMA V R32 Monobloc S is the 2nd generation of LG's R32 Monobloc series. As implied by “silence” and “supreme," it boasts reduced noise level and best performance in the THERMA V Series. It is a fully packaged piece of equipment, where the indoor and outdoor unit are combined as one module. Therefore, there is no need for refrigerant piping work since the monobloc unit located outside is connected by only water piping.

Unitherm Heating Systems have been supplying LG heat pumps for over 5 years in the Irish market. Particularly suited to new residential units and home energy upgrades with no requirement for gassing the heat pumps.

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

The THERMA V R32 Monobloc S combines the indoor and outdoor as one module. They are 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.

An important feature of the LG’s is the Blackfin technology integrated in the Monoblocs. Composed of an enhanced epoxy resin it protects vital components from various corrosive external elements such as airborne salt and pollution. We have seen this very popular on developments in coastal areas, cutting down the volumes of parts needing replacement.

Therma V is very simple to set up. Its straightforward layout and continuous operation-tracking make maintenance relatively quick and painless.

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.
