Electric water heater EKA, EKR, EWH, EKL
3. Energy saving
The high-quality CFC-free PU foam insulation and the fitted temperature control means that
our electric storage tanks are genuine energy savers.
Low storage water temperatures are especially economic. Therefore, the infinitely variable
temperature setting should be set to the lowest value that is actually required to cover the real
hot water requirement. This helps save energy and reduces the build-up of limescale deposits
in the tank.
4. Standby energy consumption of the individual series
If no water is used for a long time after the end of the water heater’s heating interval, the water
in the tank will cool down slowly but continuously due to losses at the unit’s surface.
The speed of this cooling process depends on the type of device, its size, the thickness and
the quality of the tank insulation.
This behaviour is measured during a 24-hour period at a storage water temperature of 65°C,
considering the energy input in kWh that is necessary to keep the water temperature constant
during this period.

5. Operation
All operating elements required for the operation of the electric storage tanks (EWH, EKA,
EKR) (button to adjust the temperature controller) and monitoring elements (operation indi-
cator lamp and thermometer) are included in a control panel on the front wall of the device.
Wall-mounted storage tanks (EWH, EKL) do not have an operation indicator lamp.
The button to adjust the temperature controller of the horizontal storage tank (EKL) is located
on the front (connection side).
This device is not designed to be used by persons (including children) with physical, sensory
or mental disabilities or lacking experience and/or lacking knowledge, unless these are
supervised by a person who is responsible for their safety or have received instructions on
how to use this device from any such person. Children should be supervised in order to
ensure that they do not play with this device.
