Noritz NRCB180 180,000 BTU Tankless Water Heater - HCNAC1002-NG

The NRCB180 Residential Combination Boiler allows for simultaneous residential domestic hot water and space heating, and performs at a 95% AFUE (Annual Fuel Utilization Efficiency). Its fuel‐saving performance allows the NRCB to meet "Energy Star Most Efficient" standards.

The NRCB180DV has a maximum gas input Btuh of 180,000 for hot water and 100,000 Btuh for space heating. Its maximum flow rate is 9.8 gallons per minute. The product is manufactured with 316L stainless steel and weighs only 95 pounds (gpm).

• Venting versatility: The NRCB will adjust to either PP or CPVC venting without the installer needing to make any programming changes. The venting can also easily be reconfigured to use room air.

• Recirculation capability: On the domestic hot water side, the NRCB is compatible with a recirculation loop without the need for accessory heat exchangers or controls.

• Compact construction: At less than 100 pounds, the NRCB is lighter than a traditional boiler, allowing it to save up to 80 percent in space.

• Built‐in auxiliary pump connections: An external pump control allows for a secondary heat loop, in addition to the built‐in primary pump.

• Component design: Each part of the NRCB is assembled as an individual component, simplifying servicing and replacement for technicians.

• Built‐in outdoor temperature reset: The built‐in sensor measures outdoor temperatures, allowing the NRCB to constantly operate at maximum efficiency.
