The LG Multi F MU4R25.U40 is a powerful four-zone multi-split outdoor heat pump designed to supply comprehensive heating and cooling across four independent rooms. With a cooling rating of 7.0kW and robust 7.8kW heating performance, it replaces multiple exterior condensers with a single, highly efficient outdoor unit. Utilizing high-efficiency R32 refrigerant, twin rotary inverter compression, and intelligent load modulation, it ensures minimal electrical draw alongside whisper-quiet residential operation. Anti-corrosive Ocean Black Fin protection safeguards the condenser array from salt laden air and typical UK inclement weather. Indoor units across four zones can mix high-wall, cassette, or ducted designs to match every room's styling requirements, while LG ThinQ integration lets homeowners configure individual room temperatures or heating schedules via iOS and Android apps. F-Gas certified installation is mandatory to establish flared refrigeration circuits, charge checks, and dedicated electrical feeds. It provides an exceptional central decarbonisation solution for contemporary UK households.
