"It was impressive, both technically and environmentally, that it can supply cooling, heating, and even hot water by utilizing thermal energy from the air without directly using fossil fuels."
At "Smart Energy Plus (SMART ENERGY PLUS·SEP) 2026," held on the 28th at Hall B of COEX in Seoul Samsung-dong, Oh Yoon-seok (23), a college student examining the heat pump boiler "LG Therma V" at the LG Electronics booth, said as much. The LG Therma V is a high-efficiency product that utilizes the principle of a refrigerant alternating between liquid and gas states to absorb and release heat. It can supply approximately four to five times more thermal energy than the input power.
The LG Therma V showcased by LG Electronics at this exhibition consists of an outdoor unit, an indoor unit, and a deluxe remote control. The heat pump boiler, which functions as the outdoor unit, absorbs thermal energy from the air, and the indoor unit utilizes it to supply cooling, heating, and hot water. Users can intuitively check the status of cooling, heating, and water supply through the display on the deluxe remote control.
LG Electronics has diversified its indoor unit lineup into options such as a control unit, hydro unit, and combo unit, allowing selection according to residential environments. At SEP 2026, it unveiled the combo unit alongside the heat pump boiler. The combo unit is an all-in-one indoor unit with a built-in water tank of approximately 200 liters, characterized by integrating the functions required for cooling, heating, and hot water supply into one.
Installation convenience has also been enhanced. LG Electronics integrated key system components inside the product, enabling the use of existing hot water pipes without separate refrigerant piping construction. This reduces installation time and costs while minimizing variations in construction quality by embedding core distribution pipe components. According to the company, the LG Therma V can reduce energy costs by approximately 40% to 60% compared to existing fossil fuel-based boilers and contribute to reducing carbon emissions.
The LG Therma V began a demonstration project last month at the Hyo Apartment complex in Seogwipo City, Jeju. This is a project to verify an electrification model for cooling, heating, and hot water supply suitable for domestic residential environments by installing heat pumps in an apartment complex where residents actually live, a first in Korea.
The plan is to implement a "boiler-free apartment" model optimized for Korean multi-unit housing by converting the heating and hot water methods that relied on existing fossil fuel-based boilers and gas pipes to heat pumps.
LG Electronics has been developing its heat pump business in global markets since 2008. Following its entry into the domestic system boiler market in 2011, it supplied the country's first residential all-in-one heat pump boiler in 2018. Recently, it has accelerated its expansion of domestic operations by being selected as the top contractor for the "2026 Heat Pump Adoption in Daily Life Project" promoted by the government and Jeju Island.
It is also focusing on overseas market penetration and securing technological competitiveness. LG Electronics is expanding its business scope by supplying heat pumps to residential complexes in Europe, including the Netherlands, Germany, Poland, and France. It is strengthening R&D (Research and Development) to achieve stable performance even in extreme climates by operating cold-region research institutes in locations such as Alaska, USA; Oslo, Norway; and Harbin, China, in addition to Korea.
In particular, the heat pump is considered one of the core technologies in the cleantech sector among "ABC (Artificial Intelligence·Bio·Cleantech)," which LG Group Chairman Koo Kwang-mo has emphasized as a future growth driver.
An LG Electronics official stated, "Heat pumps are emerging as a next-generation solution to replace existing fossil fuel-centric cooling and heating," adding, "Based on technology verified in Europe and business know-how accumulated over many years domestically, we will actively pursue the expansion of the heat pump market."
