Did you know that an electric water heater heats water similar to one of those portable immersion water heaters you use to heat a cup of water when you're traveling? It's true. Electric water heaters are not much more complex than that. They have two heating elements, a lower and an upper element and mount using a screw-in base or a flange mounting base. These metal heating elements get hot from electrical resistance, similar in concept to how those portable immersion heaters work.
So what happens when one or both of these heating elements goes bad? Little to no hot water is the result. But do you know which one usually goes bad first? Or how to test, repair and replace a heating element? Or the difference between a screw-in or flange type heating element? In the tutorial Electric Water Heater Troubleshooting I'll explain all that and how to troubleshoot an electric water heater, test a heating element, and how to remove and replace a faulty heating element.
