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.
Likewise, people ask, are upper and lower water heater elements the same?
Upper and lower heating elements are identical, and the temperature is regulated by the upper and lower thermostat and high limit device. Electric water heater elements can be different in size, but the most common is 12″ (300 mm).
Also question is, should both thermostats on a hot water heater be set the same?
An upper and a lower thermostat can be found under two control panels. If you want your electric water heater to work as efficiently as possible, you need to set both of the thermostats at the same temperature.
Should upper and lower thermostats be set the same?
The proper way is to have both of them the same. Normally the lower one is going to control the tank’s temperature until the lower element burns out and then the upper one will be in charge until you repair the heater.
Should upper and lower water heater elements the same?

What is a good setting for hot water heater?
The Consumer Product Safety Commission (CPSC) recommends setting the water heater at no more than 120 degrees Fahrenheit (49 degrees Celsius) to prevent scalding. Not to mention, a water heater that is set too high can unnecessarily increase your electricity bill. Of course, every house is different.

An electric storage-tank-style water heater has two thermostats because it has two heating elements. The thermostats are designed so only one element is active at a time. The reason only one element is active at a time is because it allows for smaller wire sizes and lower amperage demand when in operation.
