Ceramic bobbin heaters are a unique steatite heating element that can be installed freely for direct heating of air. In the manufacturing of bobbin heaters we use ceramic segments that we build together to desired length. The segments have recesses where we place open heating coils.A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.Ceramic heaters are easily portable and give off a great deal of heat from a small box. These heaters tend to be more energy efficient and safer than many heaters, so even though they heat up quickly, their plastic casings stay cool. A great use for this type of fan would be in a small office or tabletop.
