If you have ever wondered how a water heater works, then you’re not alone. There are many ways to learn more about this essential appliance. It works by heating water, so you might be surprised to learn that it can save you money as well. There are several parts to a water heater, but they all work together to provide hot water for your home. Read on for an in-depth look at each part of a water heater.

The first part of a water heater is the tank itself. The water is piped from the city water plant through the cold water service line and is then heated by a heating element. The hot water then exits the tank at the top, where it flows to your faucet or fixture. The tank is divided into two parts, or compartments, to heat the water. A dip tube sits at the top to prevent cold water from exiting the outlet.

Most water heaters are metal tanks containing protective lining. These tanks hold up to 40 to 60 gallons of water, and operate at pressures between 50 to 100 pounds per square inch. Because they are exposed to water, they are typically covered in insulating material to keep them from rusting. A decorative outer shell or an additional insulating blanket can also protect the unit. You’ll need to periodically check your water heater to ensure it is still operating properly.
