How Electric Water Heater Works?

You do use hot water that comes out from a water heater, but you do not know how the water is heated. It is necessary to know how it works as it will help you fix some problems in the future. The working of an electric water heater may seem complex, but it is indeed simple. Here is what goes on inside an electric water heater while heating cold water:

Tank
The tank is the most visible part of your electric water heater. It is that long cylinder which is usually a few feet high and around 20-25 inches in diameter. While the exterior part of the tank is metallic, the interior is made up of glass. This is because glass does not corrode with water. Between these two parts, there is a layer of insulation for efficiency purposes. 

Cold Inlet
The water comes from the mainline into the unit through this supply line. It enters the unit from top.
Dip TubeThe cold water from the supply line then passes through the dip tube. This tube delivers the cold water to the bottom of the unit.

Heating Elements
Electric water heaters use burners to heat water. Some water heaters may have one heating element, while some may have two: one to heat from the top and one to heat from the bottom. All the heating elements work together to heat the water efficiently.

Thermostat
The thermostat regulates the water temperature and turns the water heater on and off. If the water heater has two heating elements, it will also have two thermostats. 

Anode Rod
Anode rod is also known as the sacrificial rod. The purpose of this tiny pole on the inside of the unit is to prevent corrosion. The pole is made from stainless steel and is coated with magnesium, zinc, or aluminium. 

Hot Water Outlet
This is the supply line that carries the hot water out of the unit and delivers it to all the taps in your home. It is located at the top of the unit.
​
These are the components of an electric water heater that should be in proper working condition to satisfy your hot water needs. When any of these components stop working, you cannot heat water. To know more about the working and maintenance of your electric water heater, you should get in touch with the professional technicians as they have the proper knowledge about the different types of hot water tanks in Edmonton.
