A. O. Smith, a leader in water heating and water treatment, was recognized for excellence in product design in the 2022 Dealer Design Awards Program. The awards are sponsored by ACHR News, a leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries. More than 130 products were entered into 13 different categories and judged by an independent panel of contractors. A. O. Smith’s condensing gas tankless water heater with X3® Scale Prevention Technology took home the bronze award in the HVAC High-efficiency Residential Equipment category.

“A. O. Smith prides itself on creating innovative water heating solutions, so we’re thrilled to see this first-of-its-kind technology recognized by the Dealer Design Awards, said Robert Aldrich, residential segment development leader at A. O. Smith. “X3 Technology means you never have to descale a tankless water heater again — alleviating maintenance time for contractors and reducing ownership costs for homeowners. X3 Technology is a game-changer for the tankless industry.

A. O. Smith recently launched X3 Technology on its full line of condensing gas tankless water heaters. Designed with both consumers and contractors in mind, it prevents scale buildup in a tankless unit, eliminating the need for routine descaling maintenance, tripling the expected lifetime of a unit and enabling it to run at like-new performance and efficiency.

“These awards give us a unique opportunity to recognize the outstanding research and development efforts that go into many of the products serving the HVACR industry, and the awards give our readers an opportunity to learn about innovative installation and service solutions, said ACHR News Publisher Sarah Harding.

Winning entries in the Dealer Design Awards were featured in the July 18, 2022, issue of ACHR News, which is distributed nationally to more than 27,000 HVACR contractors, wholesalers and distributors, and other industry professionals.
