"15 Years of Expertise in One"... LG Electronics Launches New Heat Pump System Boiler

All-in-One Heat Pump System Boiler Launched in Korea
Integrated Core Components Enhance Installation Convenience
High-Efficiency, High-Performance Heat Pump Contributes to Carbon Reduction

LG Electronics is introducing a new all-in-one heat pump system boiler to the domestic market, leveraging 15 years of accumulated expertise in the system boiler business.

On May 7, LG Electronics announced the launch of its new heat pump system boiler, which integrates the outdoor unit and key system components. This new product eliminates the need for separate refrigerant piping work and allows for the direct use of existing hot water pipes in homes, significantly enhancing installation convenience. Because current installations can be utilized to the fullest, replacement of existing boilers can also be done relatively easily.

Since 2011, LG Electronics has been active in the domestic system boiler business, building up technology and business capabilities optimized for the Korean market. In particular, since 2018, the company has been the only domestic manufacturer to supply all-in-one residential heat pump system boilers. This year, LG Electronics plans to introduce a high-efficiency model, already proven in the European market, to Korea and will sequentially expand domestic production of both core components and finished products.

The new product is a high-efficiency heating and hot water system based on an air-source heat pump. It operates on the principle that the refrigerant repeatedly transitions between liquid and gas states to absorb and emit heat.

The product also meets the requirements of the government's project to supply 3.5 million heat pumps by 2035, aiming to reduce greenhouse gas emissions by 5.18 million tons. LG Electronics explained that the system can generate approximately four to five times more thermal energy than the electricity input, resulting in an estimated 40–60% reduction in energy costs compared to conventional fossil fuel boilers. It also contributes to reducing carbon emissions.

From an economic standpoint, the initial installation cost of the new system is higher than that of conventional boilers, but the energy cost savings accumulate over time, making it more economical over the entire product lifecycle, according to the company. When factoring in government subsidies, the initial investment can be recovered in about five to six years depending on the usage environment.

Additionally, the product uses R32 refrigerant—which has a 68% lower global warming potential (GWP) compared to the R410A refrigerant commonly used in existing air conditioning and heating units—thus reducing the environmental burden while improving system efficiency.

This product can reliably supply high-temperature hot water even in cold winter weather, and user convenience has been enhanced with remote control capabilities via the LG ThinQ app. The compact size and black-tone design were adopted with consideration for harmony with the building exterior.

LG Electronics is also expanding its heat pump business globally. At the recent MCE 2026, both the indoor and outdoor units of its residential heat pump system received top honors, demonstrating the company's technological excellence.

The business is also showing results. LG Electronics recently completed the supply of high-efficiency heat pumps to a new residential complex in Eindhoven, the Netherlands, and has secured additional orders in Ridderkerk, with deliveries starting in the second quarter.

The company has supplied heat pumps to more than 100,000 households in five Southern European countries including France and Spain, and continues to deliver products to large residential complexes in North Macedonia. In Germany, LG Electronics is expanding supply through strategic alliances with local installers, and in the UK, it has signed a partnership with Octopus Energy, the country's largest electricity supplier, to provide heat pumps—steadily expanding its base in Europe.

LG Electronics has established a full lineup system covering not only residential heat pumps but also commercial and industrial HVAC (heating, ventilation, and air conditioning) products. The large-scale system air conditioner, "LG MultiV i," which leads the commercial market, delivers optimal climate control for commercial buildings and large facilities where precise temperature management and integrated control are critical. In industrial markets such as data centers, factories, and power plants, extra-large cooling units known as "chillers" have been recognized for their differentiated performance and continue to drive growth.

LG Electronics is also at the forefront of developing next-generation core heat pump technologies. To develop high-performance heat pump technology that operates effectively even in extreme climates, the company operates cold-region heat pump research centers not only in Korea but also in North America (Alaska, USA), Europe (Oslo, Norway), and Asia (Harbin, China). LG Electronics continues to develop high-efficiency heating technologies through close collaboration with local universities and institutions in each country.

Jaesung Lee, President of the Eco Solution (ES) Business Division at LG Electronics, said, "Based on the technology and business experience we have accumulated in Europe and other global markets, we will pioneer the domestic market to enable customers in Korea to experience new, high-efficiency heating solutions that are also environmentally conscious."
