A control module for a water heater includes a switching module that receives a voltage supply and outputs the voltage supply to the water heater. The water heater includes an electrical junction box that receives the voltage supply. A communication module communicates with at least one of an energy meter and an energy network external to the water heater and the control module, and receives information from the at least one of the energy meter and the energy network. The control module is mounted on the water heater and the voltage supply passes through or adjacent to the control module. The control module determines an operating characteristic of the water heater based on the voltage supply and selectively actuates the switching module to turn on and turn off the voltage supply to the water heater in response to the operating characteristic and the information.

Smart energy controlled water heater

A control system for an electric water heater having an upper heating element and a lower heating element is disclosed. The control system includes a control module that controls operation of the electric water heater by selectively toggling the upper and lower heating elements between an ON state and an OFF state and a consumer interface module that allows a consumer to input a set point temperature and select an energy savings mode for the electric water heater. The control module regularly monitors hot water usage and adjusts the set point temperature by a predetermined setback amount until a capacity of the water heater matches consumer usage.

Method and apparatus for operating an electric water heater using adjustable temperature setpoints

A control for an electric water heater detects a condition of a heating element when the heating element is not being energized. A switching module is operable to interrupt power to the heating element, which de-energizes the heating element. A detector module detects the condition of the heating element when the heating element is de-energized. The detector module senses current flowing through the heating element and generates a detection signal that is indicative of the current.
