ABSTRACT:
A water heater comprising a housing defining a water heating chamber, at least a portion of the housing being metallic, and a metallic heating element disposed in the housing for heating the water, wherein the metallic portion of the housing and a metallic heating element are electrically connected such that the metallic portion of the housing is cathodic and the metallic heating element is anodic and current flows from the metallic heating element, through the water, to the metallic portion of the housing. A system for treating water is also disclosed and comprises the water heater and a collector disposed in the housing for collecting solid precipitates deposited from the water. Methods for heating and treated water are also disclosed.
