What is the use of thermostat in water system?
Electrical Water Heater Thermostats
It controls both the upper and lower elements. A thermostat is essentially a temperature-activated switch. When the thermostat senses a water temperature below its set point, it will energize one of the elements in response to this “call for heat.”
