摘要： 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.

摘要： A fuel-fired water heater has a series of control and operating components which, with electrical power being supplied to the water heater circuitry via a power switch, are electrically actuatable in a predetermined sequence to supply combustion heat to water contained in a tank portion of the water heater to return the temperature of the water to a heated setpoint temperature in response to the water temperature falling below such setpoint temperature. LED diagnostic indicating lights are wired into the water heater circuitry in a manner such that each indicating light is associated with a different one of the electrically coupled components. As the components are sequentially actuated during a water heating cycle, the LED lights are successively illuminated. If one of the components malfunctions during such heating cycle, one or more of the indicating lights remains unilluminated, with the last illuminated light being indicative of the last component in the sequence which functioned properly, thereby facilitating the ready identification of the component which malfunctioned. The LED indicating lights are supported in a single row on a housing-mounted circuit board to which electrical indicating light leads from the water heater control circuit are connected. One of the LED lights is a power indicating light and, like the other indicating lights, has a resistor in an electrical trace leading to the light. The power indicating light and its associated resistor are physically isolated from the other indicating lights and their associated resistors by an interior housing barrier wall.
