ABSTRACT OF THE DISCLOSURE An electric hot water heater energy saver incorpor- ates an electrically operated timer which is provided with contacts preferably by a timer motor. The contacts are oper- able to open and close an electric circuit, preferably several times during a twenty-four hour period. Electrical energy, typically from a 220 volt line, is connected to the timer motor and separately to the electrical contacts. The electrical con- tacts are connected in series with the electrical energy source and electrical heater element of an electric hot water heater. A step down transformer provides a signal voltage. A contactor is provided with its contacts connected across the timer motor operated contacts. A switch, preferably located remotely in a living area, is connected in series with the signal voltage and when closed, operates the contactor to supply electrical energy to the hot water heater element by the timing of the timer motor. A method of conserving electrical energy in an electrically oper- ated hot water heater forms a part of the invention.
