The first water heater was invented in 1868 by Benjamin Waddy  Maughan. Before the invention of the water heater, hot water for a bath was a time consuming luxury. Anyone wanting a bath had to heat the water in small batches over an open fire or on a stove and transfer them one by one to a bathtub. Maughan called his instantaneous water heater, the “gas geyser”, it employed natural gas to heat the water as it flowed into the tub. The geyser didn’t have a flue to vent gas vapors, so it was dangerous to use. Maughan’s  design inspired mechanical engineer Edwin Ruud a Norwegian immigrant to the US to patent his automatic storage water heater in 1889. Ruud’s water heater was a cast iron appliance with a copper heat exchanger. When the water faucet was opened , an actuator valve turned on the heat burners. In 1897 Ruud opened a company in Pittsburg, PA. The Ruud Manufacturing Company became an industry leader in the first water heater products.
