I came across this website and thought many here would appreciate it. http://waterheatertimer.org/
The owner does a great job of showing you how to set up different types of water heater timers to save kWh and $. There's also some good information on how water heaters work there.
I recently discovered that our electricity supplier, AEP, offers "time of day" rates, lower on nights and weekends and higher during weekdays. I'm planning to put our water heaters on timers and then do our clothes and dish washing at night. Both machines offer delayed start so its easy. Water should be hot for morning showers even if we shut the water heaters down at 7:00 AM. The timers (one for each water heater) will actually be mounted on the wall near our HVAC thermostat so we can override or reprogram them easily.
