Edwin Ruud (June 9, 1854 - December 9, 1932) was a Norwegian mechanical engineer and inventor who immigrated to the United States where he designed, sold, and popularized a tankless water heater. He is the founder and President of Ruud Manufacturing Company, now a division of the Rheem Manufacturing Company.

Biography
Early life
Edwin Ruud was born in the Askim parish in ÃÆ'ËÅ"stfold, Norway. He was educated in engineering at the Horten Technical School ( Horten technical to skole ) in Vestfold, Norway.
Gas Company and Fuel Manufacturing
In the 1880s, Ruud began working for George Westinghouse at the Gas Fuel and Manufacturing Company in Pittsburgh, Pennsylvania. Eight years after filing his first US patent, Ruud proposed the first five patents he would award to the Westinghouse Fuel and Manufacturing companies.
In 1889, Ruud designed a water heater design for an automatic type of water storage tank that uses a lower gas heater and a temperature controlled gas valve. He then patented the design in 1890. In October 1890, he expanded his first water heater design, under the Gas Fuel and Manufacturing Company.
Ruud Manufacturing Company
On January 22, 1897, Ruud filed a separate patent of Gas Fuel and Manufacturing Company for Automatic Water Heaters. The new design consists of a cast iron shell, coats the burner, heats the surface (a roll of copper pipe in which water flows), and a thermostat that controls the gas valve. The purpose of design improvement is, "to keep the water supply at the desired temperature at all times."
With this new design, Ruud left the Gas Fuel and Manufacturing Company to start Ruud Manufacturing, its own engineering and manufacturing store where it began to produce and popularize at home, as well as commercial and industrial water heaters. Ruud was issued his patent for the Automatic Water Heater circular tube on September 6, 1898.
Ruud's business evolves as he popularizes and enhances his instant water heater design. In 1908, Ruud Manufacturing acquired two local heating and piping companies. James Hay of James Hay Company, a heating and plumbing engineer, closed down his efforts to operate as president of Ruud Manufacturing Company in 1908. and J.H. Folsom of Folsom-Webster Co., a heating and plumbing contractor company, dissolved its partnership at Folsom-Webster Company in 1908 to serve as head of the Cincinnati branch at Ruud Manufacturing Company. In 1915, Ruud Manufacturing Company had offices in Pittsburgh, Pennsylvania; Kalamazoo, Michigan; Toronto Canada; and Hamburg, Germany.
The Ruud Instantaneous Automatic Water Heater
The Thermal Valve Model, Type F, from Ruud's Instantaneous Instant Water Heater is a design that allows users to instantly heat water for applications on demand without heating, thereby saving fuel, when not in use. Type F is capable of using LP gas, natural gas, and gasoline, requiring only a spice change, and is produced in two variations, "Standard Pressure Heaters", which are designed to operate in conditions where pressure is at least twenty-pound per square inch 1.7 bar), and "Low Pressure Heaters," where operational water pressure can be as low as four pounds per square inch (0.3 bar). Thermal Valve Models, type F heaters produced in four residential sizes reflect their output in gallons per minute: 3, 4, 6, 8. In 1915, there were about one hundred thousand Type Fs installed throughout the United States. and Canada.
Heating and Air Conditioning Equipment Ruud
Edwin Ruud died in 1932 and his widow, Minna Kaufmann Ruud died in 1953. In 1959, the water heater arm of the Ruud Manufacturing Company was purchased by the Rheem Manufacturing Company and continued operations as Rheem's division.
