Samsung and LG push heat pump boilers at Busan climate expo as Korea electrifies home heating

At the 2026 Climate Industry International Expo in Busan, Samsung and LG both centered their booths on heat pump boilers, a sign that heating electrification is becoming a mainstream consumer market in South Korea. Samsung showed its EHS All-in-One unit, which combines cooling, heating, and hot water in one outdoor unit, alongside AI data center cooling and commercial HVAC systems. LG highlighted its Therma V heat pump boiler and claimed energy cost reductions of 40 to 60 percent versus fossil fuel boilers. The expo comes as Korea's government pushes a heating electrification rollout program, which is expected to drive demand for appliances that replace gas boilers with electric heat pumps. Both companies also used the event to show efficiency features in home appliances, from AI-based energy saving modes to lower standby power and e-paper displays. For buyers, the key question is whether installation costs, grid capacity, and real-world performance match the marketing numbers.

Good to see heat pumps getting a mainstream stage in Korea. The EHS All-in-One replacing separate AC and boiler is the interesting part, especially with the government electrification program pushing adoption. Would be useful to know what the rollout target actually is and how much grid capacity is reserved for it.

Both companies are showing the hardware side, but the real bottleneck is installation and retrofits. A heat pump boiler only makes sense if the building envelope and piping are ready for lower temperature water. Also curious about service costs in Korea, since that tends to decide whether people keep them after the first winter.

LG claiming 4 to 5 times the heat energy of input power is just a COP range, not a seasonal number. Real world performance depends on outdoor temperature and hot water setpoint. Also, mass heat pump adoption means winter evening peak shifts to electricity, so the grid side matters more than the expo booths suggest.

Worth watching whether Korea's heating electrification program ties subsidies to measured performance or just equipment sales. If it pays per unit installed, you get cheap units in poorly insulated homes and unhappy customers. Metered savings or seasonal efficiency requirements would keep the market honest.

Nice to see LG showing resource circulation and the Smart Cottage getting a ZEB Plus rating. But carbon certification and zero-energy building labels vary a lot by standard. The useful metric would be actual kWh and carbon per square meter, not award badges.
