This monobloc heat pump with output-dependent control, with a highly integrated indoor module, is suitable for fast, space-saving installation. 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 via an integral buffer cylinder. The compact design is suitable for heating and DHW operation as well as for efficient cooling via 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. The Stiebel Article Number for this product is 204914.
