The films can also be used in heating panels to produce wall or ceiling panel heaters. Although heating films do not usually run at very high temperatures (typically 30 °C (86 °F) on floors and up to 40 °C (104 °F) on walls), due to the large surface area they cover, they can provide significant energy output.
The nichrome wire is wound around a ceramic core, and the number of spirals per inch vary according to the requested watt density. Potential from an alternating current source, which can either be 2 phase or 3 phase, flows through the coiled nichrome wire, heating up the wire, which in turn, heats the cartridge heater sheath.
Radiative heating elements (heat lamps) are high-powered incandescent lamps that run at less than maximum power to radiate mostly infrared instead of visible light. These are usually found in radiant space heaters and food warmers, taking either a long, tubular form or an R40 reflector-lamp form. The reflector lamp style is often tinted red to ...
A group of separate heaters can be switched to offer different heating levels. Electric showers and tankless heaters usually use from 3 to 10.5 kilowatts. Minerals present in the water supply may precipitate out of solution and form a hard scale on the heating element surface, or may fall to the bottom of the tank and clog water flow.
A constant wattage cable is composed of multiple constant electric power zones and is made by wrapping a fine heating element around two insulated parallel bus wires, then on alternating sides of the conductors a notch is made in the insulation. The heating element is then normally soldered to the exposed conductor wire which creates a small ...
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.
