The newly upgraded NCC199CDV commercial condensing tankless water heater from Noritz America offers an industry-best, 10-year warranty on its redesigned dual stainless steel heat exchangers. Now produced as a unique, single-piece structure for easier servicing, the new heat exchangers also incorporate substantial improvements in corrosion resistance (100%) and heat-shock durability (200%), Noritz notes. The re-engineered NCC199CDV also features an industry-leading Uniform Energy Factor of 0.97 and a now fully integrated exhaust non-return valve that speeds and simplifies common venting for up to six heaters without the need for additional accessories, the company adds.
