What is a Water Heater Element?
A water heater element is a critical component of an electric water heater. It is a metal rod that heats the water in the tank. There are usually two heating elements in a water heater, one at the top and the other at the bottom. When the thermostat signals that the water temperature has dropped below the set point, the heating element turns on and heats the water. Over time, the heating element can become corroded or damaged, leading to a decrease in efficiency, hot water shortages, and even complete failure.
