Company: A. O. Smith®

Product: Gas Tankless units with X3™ Technology

Description: Available in three sizes with maximum BTU/H inputs of 160K, 180K, and 199K, the product line comes with an integrated recirculation pump providing the benefit of instant hot water. Like all A. O. Smith condensing gas models, products with X3™ Technology, they are Energy Star® qualified with UEFs up to 0.93. This new technology feature extends the life of the unit three times longer than traditional tankless without requiring regular scale-related maintenance. The scale-preventing construction means that contractors will never need to perform scale-related maintenance, eliminating the need for isolation valves. The combustion system operates on a ½-inch gas line and vents with 2-inch PVC.
