Abstract

L'invention concerne un chauffe-eau à accumulation (1) équipé de dispositifs anticorrosion (5, 6, SC) à courant appliqué. L'invention concerne également un procédé permettant de mesurer régulièrement la valeur du courant appliqué (Id). Le chauffe-eau à accumulation (1) peut être également équipé d'un dispositif de protection cathodique à anode sacrificielle (4). L'invention concerne enfin des procédés de fonctionnement alternatifs permettant de protéger l'anode sacrificielle (4) ou le courant appliqué, et des procédés conçus pour commander la présence de l'anode sacrificielle (4) et son degré d'usure.
