THERMA V Monobloc Air Source Heat Pump
The THERMA V Monobloc is one of LG's most popular heat pumps and amongst the most energy efficient on the market. It is a compact "all-in-one" unit which delivers a low to medium temperature hot water supply and is available in outputs from 3kW-16 kW to suita range of homes.
The Monobloc unit is connected by water piping and so doesn't need refrigerant piping and features several energy saving components such as the inverter water pump which prevents energy wastage the wide louvre fin and heat exchanger path which conserves energy, provides an increased exchange rate. LG's pressure control sensor enables the unit to make faster and more accurate decisions about the most efficient way to operate.
THERMA V Split Air Source Heat Pump
The THERMA V Split heat pump is recommended for both new build homes as well as renovation and modernisation projects. While the Monobloc is an "all-in-one" solution, the THERMA V Split heat pump is split into an outdoor unit and a separate indoor unit; this unit manages your air source heating or cooling by zones, i.e. different temperatures in different rooms of the house.
THERMA V Split Air Source Heat Pump High Temperature
The THERMA V Split is also available as a High Temperature model which is recommended for older and lesser insulated properties as well as refurbishment projects. This model is capable of reaching a hot water temperature of 80°C in dual refrigerant systems and up to 65°C for a single refrigerant system. The system includes 2 units: the external unit can be installed up to 10m from the property so you have a good deal of flexibility when choosing where to put it.
THERMA V Monobloc Air Source Heat Pump R32
The latest addition to LG's THERMA range is the Monobloc R32 which uses a more environmentally friendly refrigerant. R32 has a Global Warming Potential of 675 which is 70? lower than that of R410A which is used in many other air source heat pumps.
This model is highly efficient with an ErP rating of A+++ and features several extra features such as the Revolutionary Scroll Compressor with 'wet vapour' injection, heat exchangers coated in LG's Ocean Black Fin epoxy resin to prevent corrosion and a 5 to 6dB lower sound power level than previous models.
The THERMA Monobloc R32 can incorporate standard boilers and / or solar panels in the heating and cooling system design and delivers excellent 100% performance at low temperatures of -7°C.

Benefits of LG heat pumps
Reduced energy bills
LG's THERMA V is approximately up to 4.5 times more efficient than traditional boilers; it actually generates 4 times as much energy as it uses, so it's easy to see where energy bill savings come from.
Lower carbon footprint
75% of the energy the THERMA V uses is from the air outside and just 25% comes from electricity. This is a significantly reduction in CO? emissions compared to traditional boilers which burn fossil fuels like oil or gas. In fact, in some situations they can cut a home's carbon emissions by as much as 50%.
Easy to maintain
The average life of a boiler is just 8-10 years but as long as your air source heat pump gets an annual service it should need very little maintenance and many can last for up to 25 years.
Heat your home all year round
Air source heat pumps by LG will work in the worst UK temperatures as they are designed to cope with temperatures as low as -25°C.
Seasonal auto mode
The system will monitor the temperature outside and automatically adjust its operation to compensate, saving energy and adding that extra touch of convenience.
Lengthy 7 year warranty
LG offer an impressive 7 year warranty with their heat pumps which should give you real peace of mind that you're investing in a high quality product.
Emergency operation feature
Should anything go wrong, the THERMA V includes an emergency operation feature which will ensure heat production continues until an engineer can address the issue. For minor problems in sensor malfunctioning the heat pump cycle is forced to operate. For bigger problems caused by defects in the pump's cycle parts, the electric heater element will run instead.
Convenient and smart controls
LG's heating controller features a 4.3-inch wide color LCD display with a reactive touch LED panel to make controlling your heat pump system simple and easy. In addition, LG also offer a smart control system called called ThinQ. This app connects all LG appliances in your home so you can control and monitor them wherever you are. You can even view energy consumption and send operational data to your service engineer.
Earn money with the RHI
When installed by an MCS accredited company, an LG THERMA V air-to-water heat pump could earn you money through the government's Renewable Heat Incentive (RHI) scheme. The RHI scheme pays owners of eligible renewable heating systems for each unit of energy the heat pump generates for 7 years after it has been commissioned. The exact payments you'll receive will vary depending on the current tariff, the technology installed and how much energy you generate.
How much does an LG heat pump cost?
The average cost of installing an air source heat pump system is around £6,000 – £12,000. The exact price you'll pay will depend on the model and size of the heat pump you choose and which company to carries out the installation.
Once the heat pump is installed you can look forward to many years of energy savings and potential earnings through the Renewable Heat Incentive (RHI) scheme which will go a long way towards repaying your investment.
