    en.wikipedia.org/wiki/Cartridge_heater

    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.

    en.wikipedia.org/wiki/Home_wiring

    Homes typically have several kinds of home wiring, including electrical wiring for lighting and power distribution, permanently installed and portable appliances, telephone systems, heating or ventilation system control, and increasingly for home theatre and computer networks. [1]

  4. Electric heating - Wikipedia

    en.wikipedia.org/wiki/Electric_heating

    Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators. Alternatively, a heat pump can achieve around 150% – 600% efficiency for heating, or COP 1.5 - 6.0 Coefficient of performance , because it uses electric power only for ...

  5. Heating element - Wikipedia

    en.wikipedia.org/wiki/Heating_element

    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 ...

  6. Space heater - Wikipedia

    en.wikipedia.org/wiki/Space_heater

    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.

  7. Resistance wire - Wikipedia

    en.wikipedia.org/wiki/Resistance_wire

    Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures, up to 1,400 °C (2,550 °F). When used as a heating element, resistance wire is usually wound into coils.

    In both those instances the white wire should be identified as being hot, usually with black tape inside junction boxes. The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking ...

    en.wikipedia.org/wiki/Water_heating

    Tiny point-of-use (POU) electric storage water heaters with capacities ranging from 8–32 L (2–6 gallons) are made for installation in kitchen and bath cabinets or on the wall above a sink. They typically use low power heating elements, about 1 kW to 1.5 kW, and can provide hot water long enough for hand washing, or, if plumbed into an ...
