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. Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right ...
Although the General Services Administration had Specification W-H-193 [13] for electric space heaters, it was replaced in 1995 by the UL standards. Additional information on portable-heater safety may be found at the Department of Energy's Energy Efficiency website. [14]
Local fire departments responded to an estimated average of 44,210 home structure fires caused by heating equipment, including space heaters, each year from 2016 to 2020, per the NFPA.
A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.
There is also thermostat controlled operation installed in modern kerosene heaters as well. 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.
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.
