Abstract (en)
The heater (1) has a sacrificial anode (5) surrounding an impressed current anode (6), and a conformation suitable for avoiding contact of the impressed current anode with water of a tank (2) of an electric water heater before consumption of the sacrificial anode. The impressed anode is in electrical contact with the sacrificial anode. Dimensions of the sacrificial anode are greater than the dimensions of the impressed anode. The sacrificial anode is mounted on a support or a retaining sheath (3) by an elastomeric sleeve.
Abstract (fr)
Un chauffe-eau électrique à accumulation à double protection cathodique comporte une anode sacrificielle (5) et une anode (6) à courant imposé associées de manière à fournir une protection cathodique, même en l'absence d'alimentation électrique. L'anode sacrificielle (5) entoure l'anode (6) à courant imposé, de manière à éviter tout contact de l'anode (6) à courant imposé avec l'eau de la cuve (d'eau) avant consommation de l'anode sacrificielle (6).
