WHP S is the ultra-flat 50 litre mini storage tank that connects up to two energy sources (e.g. heat pump, boiler or other) and performs the functions of a hydraulic separator and distribution manifold for up to 2 zones. The internal diaphragm and the configuration of the secondary connections allow for proper fluid stratification. The dedicated heat pump connection (max. 4.5 m³/h) ensures full utilisation of the storage volume, promoting greater service continuity. If the connection of an additional energy source, such as a boiler, is not possible, WHP S is equipped with a connection for the connection of an electric heater (up to 3kW). The module is supplied with an automatic air vent valve and temperature thermowell. it is fully insulated and can be used in both heating and cooling systems.
