Abstract:
An electric storage water heater with double cathodic protection includes a sacrificial anode (5) and an impressed current anode (6) combined so as to provide cathodic protection, even in the absence of a power supply. The sacrificial anode (5) surrounds the impressed current anode (6) so as to prevent any contact of the impressed current anode (6) with the water of the water tank before consumption of the sacrificial anode (6).
