Table for the determination of the connected load (kW, fitted heater type) to heat the tank water from 10° C to
85° C (reduction factor if tank water is to be heated from 10° C to 65° C: multiply value give in the table by 0.73).

Please note for electrical connection: The fitted heater types REU, RDU, RUL, RDW can be connected
directly to the mains. For the fitted heater types RSW, there needs to be a contactor in the distributor so that the
temperature sensor installed in the fitted hea-ter is able to switch the voltage for the heating elements via a control
line.
