Electric Range - Calrod™ Heating Element Construction

The heating elements on some GE Appliance and Hotpoint ranges are called Calrod™ heating elements. This is a specific name branded on the metal circle in the center of the electric coil. Newer electric coil ranges have sensi-temp electric burners and are not branded with the Calrod™ name.

Understanding the Construction of the Calrod™ Heating Element

The Calrod™ heating element is manufactured by threading a coiled wire through a metal (steel alloy) sheath. Magnesium Oxide is poured around the wire to keep it centered in the sheath. The ends of the element are sealed with a ceramic material. The sheath is then formed to fit the oven cavity. If the Calrod™ is to be used as a surface burner, the side of the sheath is flattened and the element is formed into the familiar surface burner coil. This flattened side provides a flush contact with the bottom of a cooking vessel, thus transferring heat into the vessel efficiently.
