New models combine advanced scale prevention with contractor-friendly features

ASHLAND CITY, Tenn. (Aug. 14, 2023) – State Water Heaters, a leading manufacturer of commercial and residential water heaters, announces the launch of its Concentric Vent Non-condensing Tankless Water Heater line with X3® Scale Prevention Technology. Expanding this patented technology to additional State tankless units showcases the company’s commitment to combating the number one enemy of tankless water heaters—scale buildup.

Scale accumulation in a tankless water heater compromises efficiency and performance while increasing maintenance costs. State’s breakthrough X3 Scale Prevention Technology ensures uninterrupted functionality, eliminates the need for scale-related maintenance and extends the lifespan of tankless units three times longer than unprotected units. Now, State Water Heaters is introducing this breakthrough technology to its non-condensing concentric vent tankless water heaters, offering residential contractors top-of-the-line technology in a lower-cost unit.

“Scale buildup has long been a major obstacle for tankless water heaters,” says Isaac Wilson, senior product manager at A. O. Smith. “With our X3 Technology, we’re addressing this challenge head on, ensuring like-new performance for the life of the product. By expanding X3 Technology to non-condensing models, we’re revolutionizing the market and empowering builders and installers with exceptional scale prevention capabilities for superior efficiency.”

Designed to meet the unique needs of industry professionals, this innovative product simplifies installations thanks to contractor-preferred concentric venting. The unit accommodates long venting runs and features quick natural-gas-to-propane field convertibility for added flexibility.
