Water heater with an electrical heating element connected to alternating current |
摘要 |
Undesirable calcareous deposits (scale) on the electrical heating element (2) are to be avoided. To this end, the latter is made of anodically passivable material and in addition connected to a DC source (5). The electrical heating element (2) then acts as an anode on which no scale is deposited. <IMAGE>
