2. Kerosene heater - Wikipedia

   en.wikipedia.org/wiki/Kerosene_heater

   However, most kerosene heaters do not require electricity to operate. Most heaters contain a battery-operated or piezo-electric ignitor to light the heater without the need for matches. If the ignitor should fail the heater can still be lit manually. The Japanese non-vented "fan" heater burns kerosene gas and is known as a gasification type ...

   Typical fan heater's internal parts. The picture immediately to the right (the top on the mobile site) shows most of the component parts of a typical plug-in electric fan heater. The heating element is the coiled wire frame located behind the fan blades. The thermostat is at the top left. The heat (wattage) selector switch is at the top right.

4. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   Electric heating or resistance heating converts electricity directly to heat. Electric heat is often more expensive than heat produced by combustion appliances like natural gas, propane, and oil. Electric resistance heat can be provided by baseboard heaters, space heaters, radiant heaters, furnaces, wall heaters, or thermal storage systems.

5. Heating element - Wikipedia

   en.wikipedia.org/wiki/Heating_element

   Thick-film heaters are a type of resistive heater that can be printed on a thin substrate. Thick-film heaters exhibit various advantages over the conventional metal-sheathed resistance elements. In general, thick-film elements are characterized by their low-profile form factor, improved temperature uniformity, quick thermal response due to low ...

6. Electric heating - Wikipedia

   en.wikipedia.org/wiki/Electric_heating

   An electric heater is an electrical device that converts an electric current into heat. [1] The heating element inside every electric heater is an electrical resistor , and works on the principle of Joule heating : an electric current passing through a resistor will convert that electrical energy into heat energy.

7. Salamander heater - Wikipedia

   en.wikipedia.org/wiki/Salamander_heater

   Salamander heaters date back to at least 1915. In the early 1940s, W.L. Scheu of Scheu Manufacturing Company, a producer of temporary portable space heating equipment, developed the modern salamander heater to provide warmth to allow construction crews to work in inclement weather. Sales spread across the US, and by the 1950s, to Europe.
