Combined GBK water heater operates in the same manner as the electrical GB water heater
however, it has also been fitted with the cooling water heat exchanger allowing the sanitary
water to be heated by alternative sources of energy (e.g. central heating, solar collector or heat
pump). The two heating systems - electrical heating element and heat exchanger - can operate
singly or concurrently. While the combined water heater is connected to the water supply system
in the same manner as the GB model, the connection to the additional energy source has to be
made as well. The inlet of the heating medium into the cooling water heat exchanger is colour-
coded blue, while the outlet is colour-coded red. GBK water heaters can also be connected to
the return hot water pipe. The return hot water pipe makes hot water instantly available at all
points of use simultaneously. The return pipe can be connected to the inlet point at the top of the
water heater after removing the plastic cap and unscrewing the stopper. The return pipe
elements can also be purchased at any authorised dealer of our products at a later stage.
POWER CONNECTION
The power lead must be fitted to the water heater prior to connecting the heater to the power
supply. In order to do this the plastic protective cover must be taken off by removing the plate
inserted into the front side of the cover. The plate can be released by carefully inserting a flat
screwdriver into the fissure between the plate and the protective cap, first next to the thermostat
knob and then into the fissure opposite the knob. Once loose, the plate can subsequently be
removed by hand. In order to remove the plastic protective cover, the thermostat knob must also
be removed and both fixing screws undone. The protective cover can be re-fitted following the
same procedure in reverse. The water heater must be connected to the power supply in
accordance with the requirements set out in the relevant standards applying to the electrical
installations. For safety reasons, a switch should be installed on the lead connecting the heater
to the power grid, i.e. a switch disconnecting both power supply poles with the minimum of 3 mm
distance between the open contacts.
