LG Air-Source Heat Pumps: Prices, Reviews and More (2024)

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 system 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.

lg air-source heat pump cost

LG air to water heat pumps and air to air 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:
