Featuring an integrated recirculation pump, a 0.97 UEF, and an unmatched 15-year heat exchanger warranty
It’s safe to say we’ve all experienced the inconvenience of having to wait for hot water to arrive at the faucet or shower. Fortunately, the all-new, award-winning NRCR Residential Condensing Tankless Water Heater Series, equipped with the latest technology Noritz has to offer, delivers hot water with virtually no wait time.
Featuring an integrated recirculation pump, the NRCR is designed to provide homeowners with reliable and instantaneous hot water for years to come. It does this by recirculating the water through the home’s plumbing system, so hot water is always available in whatever part of the house it’s needed.
The NRCR carries an ultra-high Uniform Energy Factor (UEF) of 0.97, while offering superior durability and better efficiency with redesigned and reformulated dual, stainless-steel heat exchangers. The corrosion and heat-shock resistance of this high-grade material permits an industry-leading, 15-year warranty. Available with inputs of 165,000 Btu per hour and 199,900 Btu/h, the new NRCR series delivers a premium solution to meet the growing demand for hot-water recirculation.
Green Builder magazine has awarded the NRCR its Green Innovations of the Year Award for 2020. The NRCR aims to reduce resource waste and minimizes the waste of unused potable water down the drain. It further protects the environment by heating water strictly on-demand, saving energy by eliminating the need to constantly reheat a full storage tank, as with a conventional water heater. Moreover, the material composition of the NRCR Condensing Tankless Water Heater contributes to its superior sustainability and makes it the smarter choice in terms of product longevity.
METHODS OF RECIRCULATION
Some homes have a pre-built loop that is ready to take advantage of a recirculation pump working in conjunction with the water heater. If a home lacks a dedicated return line, and homeowners want to avoid the cost of adding one, a crossover valve can be installed.
Our CSV-BPK Crossover Valve Kit is a simple-to-install component that effectively provides hot-water recirculation without the need for a conventional, dedicated return line from the farthest fixture to the water heater.
MODES OF RECIRCULATION
Learning Mode/Auto Mode
The Learning Mode on the NRCR quickly learns household water usage habits based on daily use. Once it does, it automatically triggers the recirculation loop in line with that expected usage. The correct water temperature is quickly delivered when and where it’s needed the most.
Scheduling Mode offers even more control, as you can set your schedule with a remote accessory and tailor the integrated pump’s operation to your lifestyle and scheduled needs. Water recirculates only when needed; for example, first thing in the morning or later in the evening when family members take their daily showers or baths.
The most efficient mode, On-Demand operates at the push of a button. A rocker switch or “doorbell”-style button can be purchased and installed to prime the pump for use only when you want it, in compliance with California’s Title 24 Code.
OTHER KEY FEATURES
Whole-home, hot-water service: The 199,900 Btu/h model (NRCR111-DV) meets all the hot-water needs of residences with up to 4.5-bathrooms; the 165,000 Btu/h model (NRCR92-DV) is designed for homes with up to 2.5-bathrooms.
Less-expensive and easier-to-install venting: Venting involves 2-inch or 3-inch PVC or CPVC pipe, instead of stainless steel: with vent runs up to 65 feet for 2-inch pipe; up to 150 feet for 3-inch. Also available: Common venting of multiple units with no need for a return valve.
Wi-Fi capability: Homeowner and contractor can monitor and control the NRCR remotely through a special app with on-off control, setpoint temperature adjustment, error-code checking, energy-consumption tracking, and scale-buildup detection.
Improved, low-BTU performance: The NRCR eliminates issues with high incoming water temperatures by reducing BTU output to less than 10,000 Btu, preventing water temperature fluctuations while keeping your tankless running smoothly and efficiently. Special programming allows the NRCR to maintain stable outlet water temperatures at input levels well below the listed burner minimum of 18,000 Btu/h. This unique, energy-saving feature — found in no other tankless water heater currently available — is ideal for recirculation applications, which so often involve warm water returning to the water heater for reheating. A special control mode directs the unit to bring that warm water back to the setpoint with minimal energy consumption.
Separate digital display enables easier monitoring of water heater operations by the homeowner, as well as easier troubleshooting for service tech personnel.
