As per the information from A. O. Smith, North America’s largest water heating manufacturer, its new Signature Series Tankless Water Heater with X3 Scale Prevention Technology was named a winner in Good Housekeeping’s 2025 Home Renovation Awards. 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.
Scale buildup is the number one cause of failure in tankless water heaters. The new Signature Series tankless water heater line 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.
