Best for: Tankless Technology Integration
Noritz specializes in hot water and condensing systems (no steam boilers available).
Yes — Noritz boilers are a solid mid-range option. Our editorial score is 3.9/5 based on published efficiency, climate fit, warranty, features, and price positioning. Noritz is associated with Noritz Corporation; confirm the exact model platform, parts path, and coverage rather than assuming they are shared. For a Long Island home, compare the exact matched system and written installation scope because design and commissioning can matter as much as the badge on the equipment.
Ratings are editorial comparison scores—not customer reviews, installation counts, or manufacturer endorsements.
A useful Noritz comparison starts with the exact indoor and outdoor model pairing—not the brand name alone. Home+ Air & Heat can review Noritz boiler options for homes in our covered Nassau County and western Suffolk service areas, then document whether the proposed equipment, capacity, electrical scope, and installation approach fit the project.
Before work is authorized, ask for the design method, AHRI match where applicable, installer or dealer qualification required by the manufacturer, registration responsibility, parts coverage, labor coverage, exclusions, and current incentive assumptions in writing. Those details vary by model, project, contractor status, installation date, and current program rules.
Noritz rates 3.9 out of 5 in our mid range-tier boiler assessment. The scoring reflects build quality, parts availability on Long Island, warranty terms, and how the equipment holds up in the homes we service. It fits best when tankless technology integration. Reviews are only half the picture — sizing and installation quality drive most of the failures we get called to.
This is Home+ Air & Heat's own editorial assessment as an insured installing contractor, not an average of customer star ratings.

Noritz brings Japanese tankless expertise to the boiler market, leveraging decades of water heating innovation. Founded in 1951, they've applied their tankless technology leadership to wall-mounted condensing boilers and combis. We install Noritz in Massapequa, Seaford, and Wantagh homes where compact installation and reliable hot water matter.
The CB combi series delivers both space heating and domestic hot water from a single wall-mounted unit. Parts availability runs 24-48 hours through regional distributors, with common components stocked at F.W. Webb and Sid Harvey's. The 12-year heat exchanger warranty provides solid coverage.
Noritz pricing typically comes in below Rinnai while delivering comparable Japanese quality. For homes under 2,400 square feet with 2-3 bathrooms, the CB series provides efficient heating with fast hot water recovery. The compact footprint saves valuable basement space in smaller homes.
Our bottom line: Noritz delivers reliable Japanese engineering at more accessible pricing than competitors like Rinnai. If you want tankless-style technology for both heating and hot water, Noritz offers excellent value. All condensing models qualify for PSEG rebates at 94-96% AFUE.
