volume 11 the lower heating element 16 is electrically connected to the building power supply 30 and is disposed near to a lower wall 34 of the tank 14 such that the lower heating element 18 is generally closer to the lower wall 34 of the tank 14 than the upper heating element 16 is to the upper wall 32 the lower heating element 18 receives current from the power supply 30 via control module 12 such that the control module 12 regulates the lower heating element 18 between an on state and an off state the electric water heater 10 also includes an upper temperature sensor 36 and a lower temperature sensor 38 each in communication with the control module 12 the upper and lower temperature sensors 36 and 38 are in communication with the control module 12 such that readings from the upper and lower temperature sensors 36 and 38 are transmitted to the control module 12 for processing the upper temperature sensor 36 is disposed adjacent to the upper heating element 16 to monitor a temperature of water within the tank 14 generally between the upper heating element 16 and the upper wall 32 the lower temperature sensor 38 is disposed adjacent to the lower heating element 18 to monitor a temperature of water within the tank 14 generally between the lower heating element 18 and the upper heating element 16 the temperature sensors 36 and 38 are preferably thermistors such as an ntc thermistors but could be any suitable temperature sensor that accurately reads the temperature of the water within the tank 14 during operation the control module 12 receives information from the sensors 36 and 38 for use in selectively actuating the upper heating element 16.
