Storage-tank water heaters usually do their work with no muss and no fuss. As a result, homeowners tend to forget about them until the hot water stops or the appliance fails and floods the basement. While your storage water heater only requires a small amount of maintenance, it makes sense to know how it works. You’ll have a better idea of how to fix problems when they do arise.
Different Types of Water Heaters
The two main types are storage-tank water heaters and tankless water heaters. Tankless models heat water on demand, with a heating element attached to the pipe that delivers hot water to its destination.
Storage water heaters are still the most common. They have the familiar cylindrical tank and are usually installed in a corner of the basement or laundry room, or have their own closet. A typical storage water heater stores hot water in a tank ranging from 20 to 80 gallons, and keeps it hot until its needed. Water stored in the tank has to be continually reheated so it’s ready for the next user. While these systems do suffer from standby energy loss, they are quite reliable, and don’t have many parts that can malfunction.
As is the case with tankless water heaters, a storage water heater either comes as an electric model or one that’s fueled by natural gas, propane or some other fuel source.
How Does Your Storage Water Heater Work?
First, tap water enters the top of the water heater through an inlet pipe. Inside the insulated, steel tank, either electric heating elements or a gas burner heat the water. When someone in the house turns on a hot-water faucet or appliance, hot water flows out of the water heater via an outlet and is piped to the hot-water source. While a thermostat and some safety components make the system work, that’s basically how storage water heaters work.
