This monobloc heat pump with output-dependent control, with a highly integrated indoor module, is suitable for fast, space-saving installations. It can be used for modernisation projects, since flow temperatures of up to 65°C are available all year round for room heating and DHW heating. It can be used in a wide range of different heat distribution systems, as the heat pump is separated from the heat distribution system by means of an integral buffer cylinder.  The compact design is suitable for heating and DHW operation as well as for efficient cooling by means of circuit reversal. The indoor module also contains the following components: DHW cylinder, cylinder charging pump, circulation pump, 3/2-way diverter valve, safety valve, electric emergency/auxiliary heater and the heat pump manager, which is used to control the system. 

Features:

• The air source heat pump for heating and cooling is installed outdoors
• Inverter technology allows ideally matched heating output through the variable speed compressor
• Even at low outside temperatures, the enhanced vapour injection/enhanced saturated vapour injection of the heat pump achieves a high flow temperature
• Quiet operation thanks to encapsulated refrigerant circuit and variable matched fan speed
• Improved room climate in summer with active cooling using circuit reversal
• High efficiency and low operating costs all year round, thanks to optimally matched components
• Low operating costs as mono mode DHW heating is possible
• Can be integrated into the home network and operated via a smartphone
• The integral cylinder for DHW heating is combined with a heating heat pump and integrated into the heating system.
• Space saving positioning thanks to integration of DHW cylinder, buffer cylinder and hydraulic working parts into a single appliance
• Installation requires little effort thanks to high level of integration including WPM heat pump manager
• Large area heat exchanger for high DHW demand
• Additional application due to suitability for cooling, e.g. via an area heating system
