An electric radiative space heater. Electric infrared radiant heating uses heating elements that reach a high temperature. The element is usually packaged inside a glass envelope resembling a light bulb and with a reflector to direct the energy output away from the body of the heater.
A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule heating .
Joule heating affects the whole electric conductor, unlike the Peltier effect which transfers heat from one electrical junction to another. Joule-heating or resistive-heating is used in many devices and industrial processes. The part that converts electricity into heat is called a heating element. Among the applications are:
An electric current heats the block, which in turn heats the fins. The fins then heat the air. In another type of heating element, the honeycomb disk, the block of ceramic is perforated with numerous holes. The air is heated as it flows through the holes. No fins are required for honeycomb disk heating elements. [6]
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.
Electric space heaters convert electricity into heat through the process of Joule heating. The main component of these heaters is called the heating element . Heating elements come in many different geometries and styles and can be used in either convective or radiant space heaters.
