It has both a cold water inlet that fills the tank with cold water and a hot water outlet that discharges the water from the faucet when the water is warm enough.
There is a thermostat that is mounted to the side of the internal tank. When the thermostat detects that the internal water temperature is below the preset threshold, it triggers the switch that flows electricity to the heating element.
The incoming cold water pipe attaches to the dip tube into the water heater. The dip tube distributes the incoming water to the bottom of the tank to ensure all of the water is heated entirely. When the thermostat detects that the tank’s water reaches the preset temperature, it stops the power. Then, you will get the desired temperature of warm water from your hot water tap.
