Noritz NRC111DV 199,900 BTU Tankless Water Heater - HCNAC1013-NG

Noritz NRC111DV 199,900 BTU Tankless Water Heater - HCNAC1013-NG

The NNRC111 DV Residential Tankless Water Heater utilizes a dual heat exchanger, a fusion of stainless steel and copper heat exchangers. The 100% stainless steel component captures the residual heat from the exhaust temperature to preheat the incoming water before it runs through the main copper heat exchanger. This results in dramatic reduction of carbon dioxide and increases the heater's efficiency level to over 93%!

Another benefit of this technology is lower exhaust temperatures, which means less costly PVC can be used for its venting. A PVC adapter is built into the heater for easy installation.

Features

• Heat Exchanger: Manufactured with commercial grade copper, 25% thicker piping than standard models

• Venting Options: Available as an Outdoor (requires no venting) or indoor Direct Vent (‐DV) model which includes special plastic flue adapters that are compatible with both 3" or 4" Schedule 40 and 80 PVC/CPVC pipe. The DV model can also be converted to an SV model with the use of a Conversion Kit (#SV‐CK‐3)

• Quick‐Connect: Two identical units can be linked together by using the optional Quick Connect Cord (#QC‐2) for twice the hot water capacity

• Thermal Efficiency: Fully condensing, 95% efficient for use with natural gas or propane

• Temperature Controls: Includes remote thermostat that can precisely adjust the output temperature from 100°F to 140°F with the capability to display temperatures in both°C and°F

• Power Cord Installatiohn Kit: 6' power cord is included with ‐DV models only

• Safety Devices: Flame Sensor, Overheat Prevention Device, Lightning Protection Device, Freeze Protection, Condensate Overfill

• Additional Fetures: Temperature Lockout, High Elevation Adjustment, Condensate Overflow Monitoring System, Service Reminder Function
