Abstract: A storage type gas water heater has two or more tanks providing a primary heated water storage tank from which hot water is drawn, and one or more supplementary water storage tanks that utilize hot combustion gas from the primary heated water storage tank to generate and supply temperate water to previous supplementary water storage tanks and/or the primary water storage tank. A diffuser chamber is provided between the primary heated water storage water tank and the supplementary water storage tank with combustion gas from the primary heated water storage tank vented therein. A diffuser is provided in the diffuser chamber to disperse the vented combustion gas to pre-heat (temperate) the water in the supplementary water storage tank. If more than one supplementary water storage tank is provided, each supplementary water storage tank is separated by a diffuser in a diffuser chamber with combustion gas vented therein.

Abstract: A heating assembly for a water heater may include a base, a first electric heating element secured to the base, and a second electric heating element secured to the base. The second electric heating element is electrically isolated from the first electric heating element. The first and second electric heating elements are independently switchable to provide a first heat rating of the heating assembly and a second heat rating higher than the first heat rating. A water heater assembly may include a tank defining a chamber for holding a volume of water, and the heating assembly coupled to the tank. The water heater assembly may include a second heating assembly, and may further include a controller configured to control the first and second heating assemblies to provide heating at same or different heat ratings.
