A fan heater is a heater that works by using a fan to pass air over a heating element. This heats up the air, which then leaves the heater, warming up the surrounding area. They can provide very rapid heating of a room, however may be relatively noisy in operation. They are inexpensive to buy and can be used to heat areas where other heating solutions might be difficult to install, expensive or impractical. An example of such an application is their use to heat up small shop kiosks.
