LG Electronics is launching an all-in-one heat pump system boiler in South Korea, aiming to capitalize on the shift toward electrification in the heating market. The company plans to expand adoption of residential heat pumps by offering a high-efficiency electric alternative in a market still dominated by gas boilers.
The company said Thursday the new product combines the outdoor unit and key system components into a single package. That design eliminates the need for separate refrigerant piping work and can use a home’s existing hot-water pipes, making it easier to meet demand for boiler replacements. LG Electronics has operated a domestic system boiler business since 2011 and has supplied residential all-in-one heat pump system boilers since 2018.
The new model uses an air-source heat pump that draws heat from the air to provide space heating and hot water. LG Electronics said it can deliver about four to five times as much heat energy as the electricity it consumes, cutting energy costs by about 40% to 60% compared with fossil-fuel boilers.
LG Electronics said the product meets standards tied to a government program to deploy 3.5 million heat pumps by 2035 as part of a plan to cut greenhouse gas emissions by 5.18 million metric tons. While upfront costs are higher than for conventional boilers, the company said government subsidies and energy savings could allow payback within five to six years, depending on usage conditions.
The company also highlighted environmental features. It uses R32 refrigerant, which it said has a global warming potential 68% lower than R410A, a refrigerant commonly used in heating and cooling equipment. LG Electronics said the system can supply high-temperature hot water even in low winter temperatures and supports remote control through the LG ThinQ app.
Industry observers say South Korea’s heating market remains centered on city-gas boilers, but demand for heat pumps could rise first in new housing and public buildings as carbon-cutting rules and electrification policies take hold.
LG Electronics said its heat pump business has already been tested in Europe. At MCE 2026, a global HVAC exhibition held recently in Milan, Italy, both its residential heat pump outdoor and indoor units received awards. The company also cited supply deals for a new housing complex in the Netherlands and projects serving more than 100,000 households across five countries in southern Europe.
LG Electronics is also expanding its heat pump lineup beyond residential use to commercial and industrial markets. It supplies its Multi V i system air conditioners to large commercial facilities and is promoting large chillers for industrial sites such as data centers, factories and power plants. The company operates cold-climate research centers in South Korea, Alaska in the United States, Oslo in Norway and Harbin in China to develop next-generation technologies.
Lee Jae-sung, president and head of LG Electronics’ ES Business Division, said the company will work to develop the domestic market based on technology and business experience built in Europe and other global markets.
