A review of Noritz NRCP series of tankless and condensing water heaters for the ultra-efficient domestic water heating and fast hot water delivery. The NRCP series is the most advanced group from this manufacturer, known as the ecoTOUGH, and is built for indoor use in large homes and small commercial applications with the high hot water demand. It is recommended for the homeowners who would like to have better control of water usage.
Noritz NRCP tankless water heaters are designed as direct vent indoor models for on-demand water heating, supplying up to 4-bath homes with the continuous and endless water flow. The built-in smart technology can memorize your family water usage pattern providing hot water fast and when you want it, reducing the wait time and saving water and energy.
Noritz NRCP models are available in two sizes. The NRCP1112-DV comes with the maximum power of 199,900 BTU and high water flow of 11.1 GPM, and NRCP982-DV, another indoor unit, that has a slightly lower power of 180,000 BTU and water flow of 10.1 GPM (both available on amazon.com), which makes them ideal for high demanding applications. Both models come with the superior energy factor (EF) of 0.94, making them ultra-efficient and Energy Star compliant, which ensures excellent savings and low pollution.
NRCP water heaters are mainly used in residential applications such as showers, dishwashing, and washers, but can also be used in commercial applications utilizing either natural gas or propane.
The main difference between NRCP and other models is the internal pump that allows the pre-heated water to recirculate through the system, enabling faster water delivery to the fixtures and better user experience and comfort. Water heaters can work in two recirculation modes, external with the return line and internal that does not require the return line while keeping the internal water warm. The appliances cannot be used for space heating appliances, only the potable water.
With the recirculation system inside water is always warm/hot, protecting the system from freezing. If you need a unit for both space and water heating, check out Noritz NRCP combination boilers.
Both models from NRCP series are equipped with two heat exchangers, made of the heavy duty stainless steel, protecting the system from high thermal and mechanical stress and scale build-up. Condensing operation is what brings significant energy savings, higher efficiency and flexible vent installation using the PVC and CPVC pipes.
The condensing technology of the NRCP tankless water heaters allows the use of PVC and CPVC vents up to 100 ft., due to the lower temperature of exhaust gases, making the installation easier, faster and economically reasonable. With the correct conversion kit, water heaters can, instead of the DV, use single vents (SV).
The NRCP series utilizes the dual flame burners that are capable of generating high-efficient operation with the power of up to 199,900 BTU and steady water temperature.
The modulating gas valve with the Turn Down Ration of over 10 can lower the power from high 199,900 BTU to 18,000 BTU, making it last longer and provide greater savings with the cleaner gas combustion.
Quick Connect cable makes connection of two identical heaters possible, allowing heating more water.
Direct electronic ignition allows an easy and automatic gas ignition of the burner.
The programmable remote control is built into the body of the water heater, right in the front panel for easy access. The remote controller is quite big, and due to its simple design provides all the necessary features for the high performance: function buttons, temperature settings buttons, LED indicator and large LCD display screen where you can check the operating status, temperature and error codes during the failure.

|Water flow (GPM)||0.5-11.1||0.5-10.1|
|max # of baths||4.5||3.5|
|Water/gas connections (inch)||3/4||3/4|
If you are looking to buy a tankless water heater for your large home and demanding family, get a Noritz NRCP1112 or NRCP982 as they built strong with quality materials, can provide high water flow rates of up to 11.1 GPM, heat water efficiently with the efficiency of over 90% and emit less greenhouse gasses. These are one of the most innovative models from this manufacturer, that provide hot water almost instantaneously thanks to the built-in recirculation pump, and if there is a problem with the unit, diagnostics system provides help using the error codes and history of issues.
