Abstract
An electric water heater has a tank portion in which water to be heated is stored. The stored water is heated by a vertically spaced plurality of electric heating elements extending into the tank interior. The heating elements are of unequal wattages, and serve unequal volume water zones, but provide equal heating wattage densities in each of the water zones.
