    Product details

    SET COMPONENTS: Heat pump and integral cylinder including DHW cylinder with internal indirect coil, WPM heat pump manager, cylinder charging pump, heating circuit pump, 3/2-way diverter valve, safety valve, 100 l parallel buffer cylinder and electric emergency and booster heater.

    APPLICATION: Inverter air | water heat pump with output-dependent control, designed as a compact mono block appliance for outdoor installation. Can be used for heating and DHW; also provides efficient cooling via circuit reversal. Ideally suited for use in new builds or buildings with a low system temperature. Sold in perfectly matched sets with compact indoor units for straightforward, space saving installation.

    EQUIPMENT/CONVENIENCE: Optimum noise reduction due to encapsulated refrigerant circuit and acoustically isolated compressor. With integral heat and electricity metering via refrigerant circuit data.

    EFFICIENCY: The waste heat from the inverter is used to raise the return temperature. This increases the overall efficiency of the system. Demand-dependent and energy efficient defrosting by reversing the circuit.

    INSTALLATION: Accessories for effective condensate drainage are available for both floorstanding or wall mounted installations. Integral anti-vibration mounts for direct connection to the heating system. Easy access to the electrical connection panel without having to open the appliance.
