Title (EN) ACCUMULATOR WATER HEATER WITH ADJUSTABLE CATHODIC PROTECTION
(FR) CHAUFFE-EAU A ACCUMULATION A PROTECTION CATHODIQUE REGLABLE
Abstract:
(EN) The present invention relates to an accumulator water heater (1) fitted with impressed current corrosion protection devices (5, 6, SC). The present invention also describes a method to regularly measure the value of the impressed current (Id) to be applied. Said accumulator water heater (1) can be additionally fitted with a cathodic protection device with sacrificing anode (4). The invention relates also to the alternative operating methods for the protection of the sacrificing anode (4) or of the impressed current, and to the methods designed to control the presence and degree of wear of said sacrificing anode (4).
(FR) 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.
