A. O. Smith, a leader in water heating and treatment, has combined its two areas of expertise to launch a new residential gas tankless product line with X3 Scale Prevention Technology. This new feature extends the life of the unit three times longer than traditional tankless, making it the first tankless product that maintains "like-new" performance without requiring regular scale-related maintenance. Designed with the installer in mind, the scale-preventing construction means that contractors will never need to perform scale-related maintenance, thus obsoleting the need for costly isolation valves. Further, the combustion system operates on a ½-inch gas line and vents with 2-inch PVC.
