Abstract
An electric water heater for heating a flow of pool or spa water includes an elongated metallic body of brass, bronze, aluminum or alloys thereof. A lengthwise elongated hollow in the body defines a water flow path having inlet and outlet openings directly communicating with the ends of the hollow. An electric resistance immersion heating element is positioned in the hollow between the inlet and outlet for heating a flow of water and is controlled by a heat sensing element, such as a thermostat, disposed in an opening in a thick body portion forming an elbow passage corner-turning the water flow path at one of the inlet and outlet openings. The thick body portion projects into the elbow passage and has a first face facing the opening and merging with a second face facing the elongated hollow at a convex locus extending widthwise across the elbow passage. The sensing element receiving opening extends widthwise of the convex locus. The thick body portion protects the sensing element from corrosion and erosion damage.
