This air source heat pump with output-dependent control and inverter technology is installed outdoors. The compact mono block design is suitable for heating and DHW operation as well as for efficient cooling by means of circuit reversal. It can also be used in modernisation projects as flow temperatures of up to 65 °C are available all year round for room heating and DHW heating.

Both the encapsulated refrigerant circuit and the acoustically isolated compressor make for quiet operation. The modulating fan and the wide gaps between the evaporator fins, which reduce air resistance, also contribute to the low sound power level. The combined enhanced vapour injection/enhanced saturated vapour injection cools the scroll compressor at low outside temperatures and achieves a higher heating output/flow temperature. When combined with the Internet Service Gateway, the integral heat pump manager allows the system to be controlled in the home network or from a mobile device. With integral heat and electricity metering via refrigerant circuit data. The electric emergency/auxiliary heater enables mono energetic operation. The refrigerant circuit is hermetically sealed, tested for leaks at the factory and filled with safety refrigerant R410A. The enamelled, corrosion-protected metal casing is made from hot-dip galvanised, powder coated sheet steel. Fan grille, recessed grips and cover are made from weatherproof and UV-resistant plastic.

This integral cylinder is suitable for DHW heating in heat pump mode. It can be simultaneously integrated into heating systems for the hydraulic connection and is used for delivery to/separation between the heat pump and heating circuit. Designed for heating and cooling in family houses.

The DHW cylinder comprises an enamelled steel cylinder with directly applied foam insulation, an internal indirect coil and a magnesium signal anode for additional corrosion protection. The buffer cylinder consists of a steel cylinder with directly applied foam insulation. The integral cylinder is equipped with the following components: heat pump manager, cylinder charging pump, circulation pump, 3/2-way diverter valve, safety valve with drain routed out of the rear of the appliance, T&P valve and electric emergency/auxiliary heater. The appliance is prepared for optional extension with a heating circuit with mixer. The cylinder casing consists of a plastic jacket, permanently attached at the back and sides. The front is made of sheet metal with a design cover.

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
