The heating element in a unit heater is the part that converts electric energy into heat. It is responsible for heating the air your unit heater puts out. A heating element can consist of coils, ribbons, or strips of wire, and are typically made from a metal alloy that conducts heat, such as nickel, iron, aluminum, or copper. You can equate a unit heater’s heating element to a lamp filament, as it has relatively the same form and function, just on a different scale.
Qmark’s heating elements for their unit heaters are simple metal coils that are durable and made to last. If your unit heater stops producing sufficient heat due to malfunction or old age, you may be able to repair it and save money by replacing the heating element rather than buying an entirely new heater.
