1. Function
The domestic hot water stored in the enamelled inner boiler is heated by the electrical heating element.
The end-user can preselect the desired temperature on the setting toggle. The heating is switched on
independently by the temperature control system during the heating-up times that have been set by
the responsible electricity supply company and switched off after reaching the desired storage water
temperature.. Should the water temperature become lower, for example due to water being removed
or to natural cooling-down (the high quality CFC-free polyurethane foam insulation keeps this as low as
possible), then the heating system of the appliance switches itself back on until the pre-set storage tank
water temperature is reached.
2. Hot water requirement
The hot water requirements in the household depend on the number of persons, on the sanitary instal-
lations in the apartment or house, on the installation, on the piping and on the individual habits of the
consumers.
The following table gives some guidelines on consumption figures.
The temperature of the necessary cold water for mixing at the given hot water temperature has been
assumed as being approximately 12°C.
3. Energy-saving
Our electrical storage tanks are real energy savers as a result of the high quality .environmentally-friendly,
CFC-free polyurethane foam insulation and the built-in temperature control system.
Low storage water temperatures have proved to be particularly economical. Accordingly, the infinitely
variable adjustable temperature should only be as high as the one that has been selected as being ne-
cessary for the actual hot water requirements. This helps save energy and reduces lime scale deposits
in the storage tank.
