What Are Electric Coil Heaters?

Electric coil heaters are a type of electrical heating device that transfers heat by way of a metal coil. Although there are many designs, they all have two major components: a coil and a heating unit. The heating unit generates electrical energy that is passed into the coil. As that electricity passes through the coil, it is converted into heat energy which can then pass to the surrounding medium.

This is a highly flexible type of heating device. They are often favored for their simplicity and low maintenance needs. Electric heating coils can be used to heat open-air or can be directly applied to a medium that needs heating. They are used as industrial heaters, electric duct heaters, consumer space heaters, and as parts of larger systems in many other applications.
