As a heating technology, Joule heating has a coefficient of performance of 1.0, meaning that every joule of electrical energy supplied produces one joule of heat. In contrast, a heat pump can have a coefficient of more than 1.0 since it moves additional thermal energy from the environment to the heated item.
Such a heat unit, if found acceptable, might with great propriety, I think, be called the Joule, after the man who has done so much to develop the dynamical theory of heat. [8] At the second International Electrical Congress, on 31 August 1889, the joule was officially adopted alongside the watt and the quadrant (later renamed to henry). [9]
Electric heat can be accurately applied at the precise point needed in a process, at high concentration of power per unit area or volume. Electric heating devices can be built in any required size and can be located anywhere within a plant. Electric heating processes are generally clean, quiet, and do not emit much byproduct heat to the ...
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 ...
In 1845, Joule published a paper entitled "The Mechanical Equivalent of Heat", in which he specified a numerical value for the amount of mechanical work required to produce a unit of heat. In particular Joule had experimented on the amount of mechanical work generated by friction needed to raise the temperature of a pound of water by one degree ...

Vietnam had the fastest growth in coal use in Southeast Asia during 2011-2021, at an annual growth rate of 11%. [4]Data of the Ministry of Industry and Trade (MOIT), 10 months of 2018 coal production was estimated at 34.35 million tons, up 10% over the same period in 2017, of which clean coal output of Vinacomin (TKV) was 29.6 million tons, up 10.9% over the same period last year.

I think of Joule-Lenz heating as producing, not releasing, heat. -- Joe 16:34, 28 November 2015 (UTC) @Rchandra: That is correct, the best kind of correct. For next time, maybe you can be WP:BOLD and perform the edit yourself? If someone disagree, they will revert and discuss, no big deal.
