That is the whole idea behind having the anode - it dissolves instead of your heater tank being eaten away. Water and dissimilar metals don't get along and pretty soon electrolysis sets in and the "weakest" (softest) metal is the one that suffers. By having an anode to eat away the electrolytic action is minimized on the aluminum water tank.
