WKF Duo heat pump modules are used in systems with existing storage tank systems. Their applications are
varied and they can be ordered in a range of different equipment variants. For example, external drinking
water storage tanks with a min. HE surface area of 3.0m² can be used.
The Remko drinking water storage tank, type EWS 300 is an enamelled drinking water storage tank with a
HE surface area of 3.5m². The additionally necessitated three-way changeover valve is switched over by the
Smart Control to provide HW. In a bivalent alternative application, the boiler can be connected directly to the
indoor unit (bivalent variant).
The highly efficient primary pump in the indoor unit can be used as a heating circuit pump and its speed is
regulated according to requirements. A pressure loss of max. 80 kPa is made available by the customer. If
the pressure losses on site exceed this, a separate storage tank, e.g. Remko KPS 300 must be used as a
hydraulic compensator. Then a Remko heating circuit group unmixed, type HGU, and a mixed heating circuit
group, type HGM, are available.
