Electric Water Heater Wiring Diagram

If you are changing a water heater thermostat on your hot water heater, or would just like to troubleshoot your hot water heater, you may want to know how it is to be wired.

Here is a diagram of the way a normal electric hot water heater with two elements that run non-simultaneous will be wired. This means that only one element at a time will be working and have power going to it. The top element will heat water until it is heated to your set point and then it will switch the power to the lower element to heat the bottom of the tank. This gives you some hot water quickly, and then heats the rest of the tank.
