Is water heater connected to thermostat?

Does thermostat affect water?
Each thermostat controls a heating element, which heats the water. When the water reaches the desired temperature, it’s the job of the thermostat to shut the heating element off. But if one or both thermostats go bad, it can force the heating element to run continuously, overheating the water.
Do I have to drain my water heater to change the thermostat?
Always disconnect the power or shut off the breaker before doing any work on a water heater. To change thermostats, you will need to remove the access panel and safety cover (do this for both upper and lower access panels on dual element units).

What happens when the thermostat fails on a hot water heater?
When an upper heating element or thermostat fails, the entire water heater stops producing hot water. When a lower heating element or thermostat fails, the top thermostat and element will continue to heat water in the upper half of the tank, but you will notice the hot water quickly runs out or is only lukewarm.
Why does my electric water heater reset button keep tripping?
Electric water heaters have 2 thermostats, an upper and a lower one. The reset button is a feature on the upper thermostat. You have two thermostats because the heater has an upper and a lower heating element. Each element has its own thermostat which “talks” to the other, ensuring that only one heating element is turned on at a time.
