23Id.Nr.: 123158-12FUNCTIONThe domestic water stored in the enamelled internal boiler is heated by the electrical heating insert. Theuser can pre-select the desired temperature via the adjustment knob. The heater automatically switcheson during the heating times specified by the locally responsible power utility and switches off again whenthe desired tank water temperature has been reached. When the water temperature drops, e.g. due to wa-ter being drawn off or natural cooling (kept as low as possible by the high-quality CFC-free PU-foam insu-lation), then the heater switches on again until the pre-selected tank water temperature has been reached.HOT WATER REQUIREMENTThe hot water consumption in a household depends on the number of persons, the sanitary equipment inthe home or apartment, the insulation, the piping and the individual habits of the consumer.The following table provides a number of typical consumption values:Hot water demand inlitresRequired storage water quantity inlitresat 37 °C at 55 °C with 80 °C with 60 °CFull bath 150 - 180 55 - 66 78 - 94Shower 30 - 50 11 - 18 16 - 26Washing hands 3 - 6 1 - 2 1,6 - 3,1Hair wash (short hair) 6 - 12 3 - 4,4 4,2 - 6,3Hair wash (long hair) 10 - 18 3,7 - 6,6 5,2 - 9,4Use of bidet 12 - 15 4,4 - 5,5 6,3 - 7,8Washing dishesfor 2 persons per day 16 10 14for 3 persons per day 20 12,5 18for 4 persons per day 24 15,2 21,5House cleaning per bucketof cleaning water 10 6,3 9(A temperature of approx. 12 °C is assumed for the cold water being mixed to achieve the specified hotwater temperature.)ENERGY SAVINGSThe high-quality environmentally-friendly CFC-free PU foam insulation and integrated temperature regu-lation make our electric flat storage tanks real energy savers. Low storage tank water temperatures areespecially economical. The continuously adjustable temperature should therefore only be set to the actualhot water temperature required. This helps to save energy and reduces the rate of limescale formation inthe tank.
