The Intermatic WH40 Water Heater Timer provides a convenient external override switch. Utilities in many areas of the country offer two electric rates for residential or commercial customers. One rate has the regular daytime electrical rate, the other is "off peak" rate. The off peak rate provides customers with "lower-priced" electricity during the nighttime and weekend periods. These time switches allow the customer to shift electricity use into these off-peak time periods in an attempt to save utility costs.
The Water Heater Timer will repeat a preset schedule daily. An external manual lever will allow the user to turn the water heater on and off ahead of schedule. Then, the Timer will resume the preset program at the next scheduled on or off operation.
If you have an electric water heater, you can save an additional 5%-12% of energy by installing a timer that turns it off at night when hot water isn't being used or off during your utility's peak demand times. Also, your utility company may offer an incentive to customers who install control devices that shut off electric water heaters during peak demand periods. Contact your electric utility to see if they offer a Demand Management Program. Under this type of program, the utility would offer "time of use" electricity rates that vary according to the demand on the system. Higher rates are charged during peak times and lower rates are charged during off-peak times.

This a very good product I purchased 2 of these 6 years ago and they are still working to keep my water heaters off during peak electric rate times. I bought them at my local Lowe's and they are still priced at just under $50.
