Our Expert Review
First-hand experience from our Nassau County installation team.
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.
