FIELD: heating.SUBSTANCE: invention relates to electric devices in which water is heated. An electric water heating system with limited scale depositing comprises a water-receiving tank limiting the inner accumulation space for the water being heated. The water stored in the said inner accumulation space can be heated by an electric heating element set in this inner accumulation space. Additionally an anode element and a cathode element are provided which are connected or made able of connecting to a DC power source in order to create the potential difference between the cathode element and anode element. The cathode element is installed in the inner accumulation space near the heating element. The proposed water heating system can be implemented in kettles, coffee makers, irons and washing machines.EFFECT: reduced scale deposits on the parts of an electric water heating system.15 cl, 5 dwg |
