   A steam table. Commercial food warmers are used in restaurants as well as outdoor food carts. In restaurants and hotels they may operate the same way, but on a larger scale. Buffets commonly use large, stainless steel containers with a sterno fuel source. Restaurants also use steam tables to keep multiple vessels warm at once.

3. Cartridge heater - Wikipedia

   en.wikipedia.org/wiki/Cartridge_heater

   The heating coil is the actual resistance which is where the electrical load occurs. The most common type of metal alloy used for this purpose is a nickel-chromium mixture, also known as nichrome. [6] The nichrome wire is wound around a ceramic core, and the number of spirals per inch vary according to the requested watt density.

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. Hot plate - Wikipedia

   en.wikipedia.org/wiki/Hot_plate

   A hot plate or hotplate is a heated flat surface on a stove or electric cooker on which food may be cooked. [3] It comprises a heated top which is flat and usually circular, and may be made of metal, ceramic, or heat-resistant glass, with resistive wire forming a heating element fitted underneath and a thermostat to control the temperature.

6. 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 ...

7. Halogen oven - Wikipedia

   en.wikipedia.org/wiki/Halogen_oven

   A halogen oven, halogen convection oven, or halogen cooking pot is a type of oven that utilizes a halogen lamp as its heating element. Halogen ovens are often noted for being more energy-efficient than a conventional electric oven due to their more effective heating of food and faster cooking times.
