The LG Multi F MU2R15.UL0 is a high-efficiency dual-port outdoor multi-split heat pump engineered for UK residential and small commercial applications. Operating on lower-GWP R32 refrigerant, this compact multi-room condenser links up to two separate indoor fan coil units to provide independent zone heating and cooling. Driven by LG's advanced Dual Inverter Twin Rotary compressor, the system achieves remarkable seasonal energy ratings while minimising electrical consumption and exterior running noise. Corrosion-resistant Ocean Black Fin heat exchangers protect against coastal and city pollution, guaranteeing reliable longevity throughout challenging British winters. The MU2R15.UL0 offers seamless integration with wall-mounted, cassette, or ducted indoor styles, bringing whisper-quiet operation and precision thermal control to bedrooms and home offices. Fully compatible with the LG ThinQ smart app ecosystem when connected with smart-enabled indoor units, it simplifies multi-room management. Demanding professional installation by F-Gas registered technicians, this outdoor unit provides robust domestic heating capability alongside chilled summer comfort in a compact single-fan chassis.
