An electric heater is a device that uses electrical energy to produce heat for warming up spaces or objects. It typically works by passing electricity through a heating element, such as a coil or ceramic material, which then generates heat. Electric heaters are commonly used for home heating, as well as in various industrial and commercial settings. They are portable, easy to use, and offer efficient, safe heating without the need for fuel combustion. Popular types include space heaters, baseboard heaters, and oil-filled radiators.
