World's first tankless water heater with built-in scale prevention honored for efficiency, innovative features and zero lifetime maintenance, delivering significant homeowner savings and instant hot water on demand

JOHNSON CITY, Tenn., Dec. 4, 2024 /PRNewswire-PRWeb/ -- A. O. Smith, North America's largest water heating manufacturer, today announced its new was named a winner in Good Housekeeping's . Available exclusively at Lowe's, the ENERGY STAR® certified line of premium condensing gas tankless water heaters was awarded in the "Sustainability Innovators" category for its extreme efficiency, installation adaptability, and first-of-its kind integrated scale prevention technology – which eliminates the need for maintenance and extends the lifetime of the unit by up to three-fold. More details about A. O. Smith's new residential tankless line at Lowe's and the full list of award winners can be found on .

"The professional home builders on this year's judging panel, who installed the new A. O. Smith tankless unit on 2024 projects, gave it perfect marks," said Dan DiClerico, director of the Home Improvement & Outdoor Lab at the Good Housekeeping Institute. "Fully integrated scale-prevention technology is a true game changer because it means no more annual maintenance just to keep the warranty valid, saving homeowners an additional $250 per year. Our experts were also impressed with how the one-gallon-per-minute internal recirculating pump ensures fast delivery of hot water to fixtures throughout the home when its needed."

Scale buildup is the number one cause of failure in tankless water heaters. The new features first-of-its kind, patented built-in X3® Scale Prevention Technology that provides protection for the heat exchanger, so the unit lasts three times longer than a standard tankless water heater. Homeowners benefit from like-new performance with zero lifetime de-scaling maintenance required, along with the industry's first ever "Peace of Mind" limited warranty. Unlike other manufacturers' industry-standard warranties, which automatically disqualify hard water, A. O. Smith' 15-year limited warranty covers scale-related failures should they occur. The new line also features a built-in recirculating pump, so homeowners always have instant hot water when they turn on the tap, whenever and wherever they need it.

Available in 160K, 180K and 199K BTU inputs, all models are field convertible from Natural Gas to Liquid Propane (kit included) and can be installed indoors or outdoors. They're also Ultra-Low NOx and ENERGY STAR® certified, qualifying homeowners for rebates up to $1,300 in some states. To find local rebates in your area, visit .
