About Noritz Water Heaters
Noritz water heaters represent Japanese engineering excellence in tankless water heating technology. Founded in 1951 in Kobe, Japan, Noritz Corporation has grown to become one of the world's largest manufacturers of tankless water heaters and boilers. The company entered the North American market in the 1990s and has established a strong reputation for reliable, energy-efficient on-demand water heating solutions among professional contractors and homeowners.
Noritz manufactures condensing and non-condensing tankless water heaters for residential and light commercial applications. Their EZ series offers affordable entry-level tankless performance, while the NRC condensing series achieves efficiency ratings up to 0.97 UEF. The NRCB combi-boilers provide both space heating and domestic hot water from a single unit. Noritz backs its products with up to 12-year heat exchanger warranties. Serial numbers use a YYYY.MM-SERIAL format where the first four digits indicate the year and the next two digits indicate the month of manufacture.
