Noritz NRCB Combi
Model Number: NRCB
Japanese-engineered combi boiler at value pricing.
Technical Specifications
Prices depend on sizing, venting and piping in your home, so we quote every installation.
Sizing: the right size comes from a room-by-room heat-loss calculation, not the size of the old boiler or a rule of thumb. Oversized boilers short-cycle and waste fuel; steam systems are sized to the connected radiation instead. See how we approach boiler installation.

Sizing & Installation Notes
Combi boilers like the NRCB Combi are sized on two loads at once: the home's heat loss and the peak domestic hot water demand. In most Long Island homes the hot-water load is the larger one, so we size to your household's simultaneous shower and tap use.
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.
