Noritz America Corporation recently opened a new showroom and contractor-training facility in the Atlanta suburb of Marietta, with the goal of providing handson instruction on the benefits of tankless water heating for plumbing, mechanical and HVAC tradespeople, as well as their residential and commercial customers. The newly renovated, 1,650-square-foot showcase is part of Noritz’s 13,000-square-foot distribution center in Marietta that serves as a logistical hub for the Southeastern United States.
