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 ...
The heat output of any electrical heating element can be regulated by regulating the electrical power input. PTC heating elements also can be regulated indirectly. For example, a PTC heating element with a sharp change in resistance at a particular temperature can be fitted with a constant voltage source and a variable-speed fan.
Convective space heaters utilize convection to transfer heat from the power source to a space. These heaters typically either rely on natural or forced convection. Natural convection is a phenomenon where temperature variations in an environment generate fluid flow. Forced convection heaters utilize a device like a fan to generate air flow and ...
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 cartridge heater is a tube-shaped, heavy-duty, ... The most common types of sheaths are 304 stainless steel, 316 stainless steel, and incoloy 800.
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. Heating elements are used in household appliances, industrial equipment, and scientific ...
