An electric water heater works essentially the same way as a gas water heater. It brings cold water in through the dip tube (1) and heats it using the electric heating elements (2) inside of the tank. The hot water rises in the tank and is moved throughout the home through the heat-out pipe (3).
How does an electric water heater work instantly?
How does an electric instant water heater work? In an instant water heater, cold water flows through the inlet pipe. This water is then heated using electric heating elements inside the tank. The water that is now heated rises in the tank and is withdrawn through the outlet pipe.
Which element heats up first on electric water heater?

How does a water heater heat water?
Gas water heaters use a flame underneath the tank to create heat, while electric water heaters use a heating element to warm the water. Each tank has inlets that enters and exits the tank to move the water to where you need it (i.e. shower, dishwasher, etc.).
How do you start a electric hot water heater?

Why do water heaters have two thermostats?
Electrical Water Heater Thermostats The upper thermostat is the main control component for most water heaters. It controls both the upper and lower elements. Most electric water heaters above 20 gallons have two thermostats that sense the temperature of the water in both the top and bottom of the tank.
Why do water heaters have 2 elements?
The upper element heats the upper portion of the water column. When it reaches a specified temperature, Rheem notes that it shuts off, and the lower heating element takes over, heating the rest of the water. This is an efficient, money-saving feature, as the water is heated in a consistent manner.
