Noritz NCB-H

The Noritz NCB-H brings legendary tankless water heater reliability to condensing boiler applications, delivering 95% AFUE efficiency with Japanese engineering precision and American support infrastructure.

Noritz's extensive experience with stainless steel heat exchangers translates directly to the NCB-H platform. For Nassau County homeowners familiar with Noritz tankless quality, the boiler represents a natural extension of that proven technology.

Our installation teams appreciate the NCB-H's compact wall-mount design and straightforward venting. The boiler fits easily in tight utility spaces common to Long Island construction, freeing valuable floor area for storage.

For homes in Great Neck, Manhasset, and surrounding premium communities, the NCB-H provides high-efficiency heating with manufacturer backing that instills long-term confidence. Noritz's technical support and parts availability through national distribution channels ensures serviceability.

The NCB-H features modulating burner technology that matches output precisely to heating demand, reducing energy waste and improving comfort consistency throughout the home.

Combi capability: Select NCB-H models provide both space heating and domestic hot water in a single unit, potentially eliminating the need for a separate water heater.

Condensing boilers like the NCB-H reach their rated efficiency only when return water runs cool enough to condense flue gases. We check your radiation and design water temperatures so the unit actually condenses in your home, not just on the spec sheet.

Every Noritz installation starts with a free in-home assessment covering the heat-loss calculation, venting and chimney condition, and gas or oil supply sizing. Learn more about our boiler installation process, or see current rebate and incentive programs that may apply.
