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). [1] [2] [failed verification] 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.
Oil heaters transfer heat by convection and radiation. [4] They can silently heat larger rooms, but take longer to heat up. Like infrared models, they lack a fan, but circulate heat according to a room's air patterns, which is why it may take longer for a user to discern a difference in temperature.
A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.
Unlike conventional ovens, which cook food by surrounding it with hot air, convection ovens circulate the air. Convection ovens are built with a fan placed in the back of the oven.

Its two ceramic elements bring up the heat quickly. On the low setting, it’s a 750-watt space heater; on the high setting, it’s 1,500 watts. It can also be used as a single-speed fan (without ...
