A. O. Smith produced its first residential water heater in 1939, establishing a tradition of innovation that continues to this day. In 1953, A. O. Smith shipped its first commercial water heater equipped with a “glass-lined” tank, which remains the industry standard for protecting steel from the corrosive effects of water.

In 2004, A. O. Smith reaffirmed its mastery of glass lining technology by introducing patented Blue Diamond™ glass coating on its best Conservationist® residential water heaters. Blue Diamond™ provides the ultimate protection… over twice the corrosion resistance compared to industry-standard glass lining.

The Cyclone Xi™ water heater symbolizes A. O. Smith’s clear leadership in the commercial water heating market. Introduced in 1997, The Cyclone XHE® commercial gas water heaters were designed with high thermal efficiencies to deliver maximum hot water output at the lowest possible cost, which can translate into thousands of dollars saved per year for owners of restaurants and other commercial buildings.

A. O. Smith Water Products Company is headquartered in Ashland City, Tennessee, home of the world’s largest water heater factory. The A. O. Smith network includes five manufacturing facilities in North America, plus plants in Nanjing, China and Veldhoven, The Netherlands.
