The Noritz Residential Combination Boiler (NRCB) allows for simultaneous residential domestic hot water and space heating and performs at a 95 percent annual fuel utilization efficiency. The NRCB’s 316L copper primary and secondary heat exchangers provide corrosion resistance, resulting in increased durability and a longer lifespan. A third flat plate heat exchanger for domestic water heating is made of stainless steel. The NRCB is available in two models: NRCB180DV and NRCB199DV. The former has a maximum gas input Btu/h of 180,000 for hot water and 100,000 Btu/h for space heating. Its maximum flow rate is 9.8 gallons per minute (gpm). NRCB199DV has a maximum gas input Btu/h of 199,000 for hot water and 120,000 Btu/h for space heating. Its maximum flow rate is 11.1 gpm.
