Noritz is a Japanese manufacturer whose products for the Canadian market are described on the official site as shipped directly from its manufacturing operations in Japan; its North American arm, Noritz America Corporation, is headquartered at Fountain Valley, California and operates the official noritz.com site. Noritz is best known for tankless gas water heaters and also sells condensing combination boilers, including the residential NRCB combi documented on Boilers.ca, which Noritz markets as able to run domestic hot water and space heating simultaneously.
Noritz's official blog announced on July 31, 2025 that a new Noritz warehouse in Vancouver, British Columbia, effective August 1, 2025, would fulfill Canadian wholesaler purchase orders for seven designated residential and commercial tankless water heater and boiler products — explicitly including the residential combination boiler, the NRCB — with inventory shipped directly from Japan. The post states lead times of five to seven days for most of Canada and names Barclay Sales (1-800-416-3033) for Western Canada and Fowler Sales, Inc. (519-502-7545) for Eastern Canada as manufacturer's representative contacts. Purchases run through wholesaler-distributors and their contractor customers rather than direct to consumers.
The Canadian evidence on noritz.com ends there: noritz.ca is a parked domain rather than an official Noritz site, and Noritz publishes no Canadian-language product pages. Boilers.ca found no CSA "C-US" mark statement, no CRN registration numbers and no stated Canadian warranty terms on noritz.com, so those details remain unverified. The available status on Boilers.ca rests on the official Vancouver-warehouse announcement and on the NRCB installation manual (SBB80UB-5, Rev. 04/21), which is written for both the United States and Canada — CSA B149.1 installation with ULC S636-certified plastic venting in Canada.

Each series hub lists its models, verified specifications, manuals and documented alerts.
The NRCB is Noritz's wall-hung condensing combi series: the NRCB180DV (GHQ-C2801WX-FF US) and NRCB199DV (GHQ-C3201WX-FF US), both rated 95.0% AFUE with 316L stainless steel heat exchangers and 18,000 BTU/h minimum fires, marketed by Noritz as able to run domestic hot water and space heating simultaneously.
The EZ Series is Noritz's high-efficiency condensing tankless water heater line — EZ71DV, EZ98DV and EZ111DV, rated 0.98 UEF with 12,800 BTU/h minimum fires and up to 11.1 GPM. These are DHW-only water heaters, not combis or boilers.
