Steve Vance at the AO Smith water heater plant in TN. Learning about the newest innovations in water heaters. When it comes to high efficiency water heaters, no one comes close to matching the expertise and innovation of A. O. Smith. Whether you need a gas, an electric, or a tankless water heater, the inventive minds at A. O. Smith have one waiting for you.
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.
