The majority of electric water heaters have two thermostats: an upper and a lower, located under two control panels. To ensure your electric water heater works as efficiently as possible, you should set both of the thermostats at the same temperature. Note: some smaller electric hot water heaters only have one thermostat.

Why do I need an electric hot water thermostat?
An obvious reason for interest in electric water heater thermostats is the temperature of your hot water. If you need to adjust the water temperature, the thermostat is the place to do it. Most of the time, the thermostats get some interest when you have too little hot water or no hot water. The thermostats could be part or all of the problem.
When does the electric water heater thermostat go bad?

How do dual element water heaters work?
A dual-element water heater uses two heating elements controlled by two separate thermostats. The upper element heats the upper portion of the water column. When it reaches a specified temperature, it shuts off, and the lower heating element takes over, heating the rest of the water.
