The heat pump is suitable for larger buildings built or renovated for optimised energy efficiency with heat loads between 8 and 18 kW. It works with a speed controlled compressor and delivers heat and DHW up to 65°C. It can also be used for energy saving surface cooling and for active air conditioning and room dehumidification via fan coils. The slimline indoor unit has a footprint of less than half a square metre. Minimal outdoor unit noise emissions make the heat pump the perfect solution in high-density residential areas.
