Energy regulator of an electric stove with a glass-ceramic hob. 1: Electric contacts (here closed); 2: Bimetal; 3: Heater for Bimetal. An infinite switch, simmerstat, energy regulator or infinite controller is a type of switch that allows variable power output of a heating element of an electric stove.
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 .
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.
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 ...
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:
Halogen lamps are the heating-elements in halogen ovens, infrared heaters and ceramic cooktops. Low wattage halogen lamp arrays are widely used by monitor lizard keepers. Two or three small halogen lamps can produce all the heat needed in an enclosure and are recognized by the animals as sources of heat preventing curious individuals from ...
