WKF hydraulic diagram

Functions: heating or cooling and hot water, operating mode: monoenergetic

This hydraulic diagram serves merely to assist in planning activities;

the hydraulic system on site must be planned and laid out by the installer!

WKF 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 circulation pump heating cycle and its

speed is regulated according to requirements. A pressure loss of max. 80 kPa is made available by the cus-

tomer. 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 cycle group unmixed, type HGU, and a mixed

heating cycle group, type HGM, are available.
