In 2022, the IEA (International Energy Agency) reported the European market experienced a 40% increase in heat pump sales. If you’re considering an energy-efficient and cost-effective boiler alternative, it’s worth looking at LG air-source heat pumps.
An air-source heat pump transfers heat from the outdoors to provide heating for residential spaces. The heat pump’s operation can be reversed during warmer months to provide cooling to the interior and supply hot water for both central heating and household needs.
The LG heat pump line-up is called Therma V and it’s a gas replacer in providing heating, cooling, and hot water for homes. This article will take you through 5 LG air-source heat pumps and highlight what to keep in mind when choosing a heat pump for your home.

On average, the total cost of a heat pump varies between £6,000–£12,000 including the heat pump itself and installation. While choosing the best air-source heat pump for your budget, consider the following factors:
LG air-to-water heat pumps provide both building heating and the required domestic hot water. LG heat pumps are very flexible systems that can be connected to other devices such as solar cells to reduce the energy needed as input and optimise the resource potential.
LG heat pumps are inverter controlled, which means that they adapt to demand and they only use the energy necessary to operate without performing at full power. These heat pumps are designed to adjust the compressor speed to maintain the desired temperature without switching the compressor on and off.
LG offers a range of air-source heat pumps THERMA V which comes in the following models:

The THERMA V Split Heat Pump is an air-to-water heat pump with both outdoor and indoor units. It is a great choice for those seeking enhanced control over their heating and cooling systems, especially for larger properties.
The LG THERMA V Split operates without relying on fossil fuels, contributing to its environmentally friendly nature. Furthermore, it is energy-efficient and offers various outputs, from 3kW-16kW, accommodating various home sizes and types. The THERMA V Split is typically pricier than other models due to its increased capacity. This model comes with outdoor and indoor units which ensure different heating or cooling in different rooms of the house.
The THERMA V Split High-Temperature Heat Pump is a specialised solution for applications requiring powerful heating capabilities. It can provide hot water and heating at temperatures as high as 80°C, even in extremely low temperatures as low as −15°C and −20°C. This makes it particularly suitable for older properties with less insulation and refurbishment projects. It is a perfect choice for individuals who prioritise reliable performance and high capacity, especially in low-temperature conditions.
The THERMA V Monobloc offers a range of outputs from 3kW-16kW, catering to various home sizes and types. It incorporates an energy-saving inverter water pump, preventing unnecessary energy consumption. LG’s pressure control sensor empowers the system to assess its surroundings and make prompt and precise judgments on optimal operation methods. The THERMA V Monobloc is available in both monobloc and split versions, with a maximum output temperature of 65°C. Despite the modest output temperature, its capacity and efficiency make it a popular option.
This model stands out for its use of a more environmentally friendly refrigerant and has a lower Global Warming Potential compared to R410A, which is commonly used in other air-source heat pumps. The R32 refrigerant has a Global Warming Potential of 675, which is 70% lower than that of R410A.
Moreover, the Monobloc R32 model is exceptionally efficient, boasting an ErP rating of A+++. It also comes with various additional features, including the Revolutionary Scroll Compressor with ‘wet vapour’ injection, and heat exchangers coated in LG’s Ocean Black Fin epoxy resin to prevent corrosion.
One of the noteworthy advantages of the THERMA Monobloc R32 is its flexibility to incorporate standard boilers and/or solar panels into the heating and cooling system design.
The THERMA V R32 Silent Monobloc is the second generation of LG’s R32 Monobloc series. Having received the Quiet Mark accreditation, it caters to individuals who prefer quiet heat pump solutions. It operates as quietly as 32 dB which can be compared to the human whisper.
The THERMA V R32 Silent Monobloc can be installed within a minimum of 5 metres from neighbouring houses. It is also a highly efficient heat pump that uses eco-friendly R32 refrigerant and R1 scroll compressor.
