Heaters and methods of manufacturing ceramic heaters are provided. The heater includes a ceramic cylindrical-shaped body and an electrical connector connected at one end of the body. The electrical connector may be a screw-in connector. The heater also includes one or more resistance coils, filaments, wires or the like, that are embedded in the ceramic body and are electrically coupled to the electrical connector. The heater can include either one coil to provide radiated thermal output in a 180° range or two coils to provide radiated heat in a 360° range. The heater is connectable to a base coupled to an electrical source to energize the heater. The method of manufacturing enables the heater to be produced with either one coil or two coils, thereby providing a manufacturing process that can produce heaters having various capabilities.
