The reason that ceramics are used in a number of different types of heaters is that they are relatively easy to heat without the fire and burn risk produced by coil heaters. Coil heaters generate heat by running an electric current through numerous metal coils, causing them to glow and become hot enough to burn. Ceramic heaters on the other hand use ceramic plates that are attached on the edges to a few metal coils; the coils are heated in the same manner as a coil heater, but the heat produced is readily absorbed by the plates and distributed into the air. Ceramic heaters don't become as hot, release their heat more quickly, and cool down much more readily than their coil counterparts once the heater is turned off.
To speed up the process even more, many ceramic heaters contain multiple plates so that a smaller amount of ceramic material has to be heated by each element in order to be effective. Ceramic heaters are often used to provide directed heat to small or large rooms using fans that are built in to the heater itself, with thermostats on the heater making sure that they don't overheat. To help prevent fire hazards, the fans will continue to run for a few minutes once the heating elements have been turned off so as to cool the ceramic plates down even faster. Heaters equipped with these options can be used almost anywhere, and generally feature a tilt detection unit on the bottom that will shut the heater off if it falls over as an additional safety feature.
Ceramic heaters are made of ceramic tubes and rods, which resist corrosion. This is a benefit if the space that needs to be heated is humid. Ceramic heaters offer a clean source of heat, as they don't create any dust, fumes or smells. Ceramic space heaters warm up a room quickly, as they are able to reach full operating temperature within five minutes of being turned on, and will spread heat evenly from floor to ceiling.
