Abstract

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.A dual cathodic protection electric water heater has a sacrificial anode (5) and an anode (6) associated with an imposed current so as to provide cathodic protection, even in the absence of a power supply.

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).

Figure imgaf001
The sacrificial anode (5) surrounds the anode (6) with imposed current, so as to avoid any contact of the anode (6) with imposed current with the water of the tank (water) before consumption of the sacrificial anode (6).
