LG is expanding its push into home heating with three new indoor units for its air-to-water heat pump systems, aimed squarely at European homes that are short on space but big on comfort and efficiency. The new Combi, Hydro and Control Units share a clean, unified design that has already picked up a 2026 iF Design Award, and they’re built to work with LG’s latest R290 Monobloc outdoor units using a low‑GWP natural refrigerant.

All three units get a modern 6.8‑inch color touchscreen, built‑in Wi‑Fi and LG ThinQ app support, so homeowners can tweak heating, cooling and hot water from their phones and see basic status via an LED strip at a glance. LG has also shrunk the overall volume compared to previous generations by reorganizing internal components, making it easier to tuck these into utility rooms, closets or other tight corners common in European apartments and houses.​

The Combi Unit is the all‑in‑one option: it handles space heating, cooling and domestic hot water in a single box, with an integrated 200‑liter Duplex stainless steel tank and temperature sensors to keep hot water output stable even when demand spikes. LG routes the piping connections to the rear to simplify neat installs, and offers a Two‑Zone version with a built‑in mixing pump group and buffer tank, which lets installers set up separate temperature zones in the home without a pile of extra hardware.​

The Hydro Unit targets projects where you already have a separate hot water tank or a different system layout, cutting its volume by more than 30 percent versus the previous model while integrating a three‑way valve, drain pan and a larger 12‑liter expansion tank. Everything is front‑access, and a new bracket‑type mounting design is meant to make one‑person handling more realistic, which should appeal to installers who want faster, cleaner jobs in renovation scenarios.

The Control Unit, meanwhile, strips out direct hydraulic connections and focuses purely on system control via terminal block wiring, which means it can squeeze into even smaller spots while still managing the heating system and built‑in electric heater logic. That approach reduces the number of separate control boxes and accessories needed, giving installers more flexibility to tailor setups to different building layouts and helping homeowners get a tidier, more integrated system overall.​

Paired with LG’s R290 Monobloc outdoor units, the new lineup is designed to deliver stable heating even at outdoor temperatures down to around minus 28 degrees Celsius and domestic hot water up to about 75 degrees Celsius, depending on installation conditions. Because it’s a monobloc design, only water pipes run between indoors and outdoors rather than refrigerant lines, which can simplify planning, reduce potential leak points and make it easier to adapt these systems to existing homes.​

LG plans to roll out the new indoor units across Europe starting in the first half of this year, though exact timing will vary by country. For LG, this launch is as much about installer‑friendly engineering as it is about end‑user comfort: by tightening design, controls and integration around a low‑GWP refrigerant platform, the company is clearly positioning these systems as future‑proof options for homeowners navigating stricter climate and energy rules across the EU.
