A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
In the 1920s and 1930s Crosthwait invented a vacuum pump, a boiler, and a thermostat control, all for more effective heating systems for larger buildings. Some of his greatest accomplishments were for creating the heating systems for the Rockefeller Center and New York's Radio City Music Hall .
Edwin Ruud (9 June 1854 – 9 December 1932) was a Norwegian-American mechanical engineer and inventor who immigrated to the United States where he designed, sold, and popularized the tankless water heater.
Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, invented the radiator between 1855 and 1857, which was a major step in the final shaping of modern central heating. [ 17 ] [ 18 ] The Victorian cast iron radiator became widespread by the end of the 19th century as companies, such as the American Radiator Company ...
A household radiator. He is credited as one of the inventors of the radiator, which significantly contributed to modern central heating systems. He gave it the name "hot-box". San Galli's claim as the inventor of the heating radiator is disputed. It appears that he is one of several people who contributed to the development of the heating ...
Home gas heating controls cycle using a mechanical or electronic thermostat. Gas flow is actuated with a valve. Ignition is by an electric filament or pilot light. Flames heat a radiator in the air duct but outside the flue, convection or a fan may distribute the heat.
U.S. patent 2,526,874 was issued on October 24, 1950 – Apparatus for heating or cooling atmosphere within an enclosure. U.S. patent 2,535,682 was issued on December 26, 1950 – Prefabricated refrigerator construction. U.S. patent 2,581,956 was issued on January 8, 1952 – Refrigeration control device.
In 1883, he developed a thermostat, which he deployed at the State Normal School. He called the instrument an "electric tele-thermoscope" in the patent application. It was a bi-metal coiled thermostat with a mercury switch, which could be used to ring a bell to alert the fireman to open or close the heating damper.
