Charles S. L. Baker and his assistant demonstrating a heating/radiator system Baker worked over the span of decades on his product, attempting several different forms of friction, including rubbing two bricks together mechanically, as well as using various types of metals.
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.
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 ...
The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason and Scot Rory Gregor developed a primitive radiator in 1841 [4] and received a number ...
The blower motors on these single-stage furnaces consume more energy overall because, regardless of the heating requirements of the space, the fan and blower motors operate at a fixed-speed. Due to its One-Speed operation, a single-stage furnace is also called a single-speed furnace.
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.
San Galli received a radiator patent in 1857, [2] while American Joseph Nason developed a primitive radiator in 1841 [3] and received a number of U.S. patents for hot water and steam heating. Nason's patent for tapered pipe threads in particular is cited by 1930s writer Ara Marcus Daniels as the key development in the birth of the radiator. [3]
It consisted of a new style of heat exchanger in a sheet metal cabinet—a highly efficient, lightweight replacement for the bulky, slow-responding castiron radiator. In 1931, The Trane Company developed its first air conditioning unit, the Trane unit cooler, and in 1938 its first centrifugal refrigeration machine, the Turbovac.
