All units with appropriate garage space, can be equipped with an additional fresh water tank. This tank is mounted in the garage area and can be filled through the connection box. The standard Smart Home system will facilitate easy topping up by controlling and monitoring the contents of the tank and regulating the filling valve accordingly.

The extra tank serves as a storage tank and can eventually be pumped into the larger, main fresh water tank. After the content has been pumped into the main tank, it will flow to the pressure pump and can be used in the regular fresh water circuit.
