Noritz America has announced it will offer a 25-year warranty on the dual stainless-steel heat exchangers used by four of its residential condensing models.

The 25-year warranty will apply to single-family home applications using any of four models in Noritz’s EZ Series of residential condensing tankless water heaters, first unveiled in April 2017: EZTR50, EZTR75, EZ98, and EZ111. All have a Uniform Energy Factor (UEF) of 0.96, and all are specially engineered for tank-replacement applications.

In addition to the dual stainless steel heat exchangers that, with proper maintenance, offer a greater resistance to corrosion and scale buildup, the four water heater models share three critical design features. Unique to the EZ Series, these features are meant to reduce a homeowner’s upfront investment by sharply curtailing the installation time and cost for the plumbing or HVACR contractor:

• Top-mount, hot-water and cold-water connections that reduce the amount of new-plumbing work normally required by a tankless-for-tank replacement.
• Maximum venting flexibility with four different options, including outdoor (OD), direct vent (DV), single vent (SV) and 2-inch flex vent. The fourth option utilizes the existing B-Vent, formerly used by the tank water heater being replaced.
• The possibility of reusing the tank unit’s half-inch gas line, thus avoiding the substantial expense of running a new gas line.

In addition to being offered separately for indoor or outdoor installation, these new units are available in their own “EZTR Bundle” packages that include materials and accessories for direct indoor replacement of 50- and 75-gallon, tank-type water heaters.

“Noritz has always believed that our products offer contractors and their customers the very best quality in the tankless water heater industry, and now we are backing up that belief with this new warranty,” comments president and chief operating officer Jay Hassel.

“We are the only water heater manufacture offering a warranty like this,” he continues. “It’s a bold statement, but contractors and their customers need to be confident in their purchases, and this warranty is intended to give them that confidence. Now installers can tell the homeowner: ‘We install the Noritz EZ Series because it’s the best product with the water heater industry’s very best warranty.’”
