Check out why Noritz tankless water heater is an excellent solution for your home? See the expert review of the Energy Star and condensing models. Find the top features and benefits designed for domestic water and hydronic home heating.
Noritz manufacturer features an impressive selection of tankless water heaters and boilers for residential and commercial use.
All home sizes are covered, from the smaller one with one bath to larger homes with multiple baths, Jacuzzi and hot tubs, and applications that require higher hot water delivery.
In addition to tankless, Noritz boilers can be used for both water and space heating, and are called combination boilers.
Here is the list of the available Noritz water heaters built for domestic hot water production and space heating, found as the high-efficient and mid-efficiency groups:
Noritz CB series. With the two sizes available, Noritz CB combination boilers are designed with the maximum power of 199,000 BTU and a high 95% efficiency for powerful but cost-effective water heating.
Built as the direct vent heaters, they are ideal for those homeowners who prefer simple installation and having one unit to supply hot water and provide space heating, such as hydronic applications.
NRCP condensing series. Noritz tankless water heaters from the NRCP series are offered as indoor or direct vent models, designed with the latest technology for the ultra-high efficiency, low NOx operation, and fast water delivery.
Thanks to the internal circulation pump and two operating modes, the NRCP series can produce lots of hot water, reaching a high water flow of 11 GPM, making it ideal for 4-bath homes.
NRC series. The NRC series offers tankless models designed in four different sizes for indoor and outdoor installations and high efficient water heating using both natural gas and propane.
The smallest unit has the maximum gas input of 120,000 BTU while the largest has 199,900 BTU, easily covering up to 4 baths.
NR series. The NR series is the group of four economy and mid-efficiency tankless water heaters that can heat water with an efficiency of up to 85%.
Noritz NH series. Hydronic tankless boilers from the Noritz NH series are specifically designed for radiant heating applications. Hydronic boilers come in two sizes and for indoor installation; NH150-DV with the maximum gas input of 150,000 BTU and NH199-DV with 199,900 BTU.
What I like on Noritz tankless water heaters are the superior and superb features such as two the most important elements; dual-flame burner and commercial-grade heat exchanger. Another great thing about Noritz is that this company, builds almost all of its parts, with no outsourcing.
Noritz tankless water heaters can perform with the 83-97% energy efficiency, making them environmentally friendly or "green", great energy savers, and some Energy Star approved. One of the most efficient tankless water heaters from the Noritz is the NRC98 model.
A dual flame burner is one of the latest technologies used in Noritz water heaters, while most of the competitors utilize the single flame burners. Noritz superior technology allows greater performance, efficiency, and cleaner gas combustion.
Even with the higher water flow rate, a dual flame burner increases the heating output. Tankless models with the two rows of burners are not only powerful, but they are not harmful to the environment as they produce less greenhouse gases and provide hot water with less fluctuation in the temperature (less cold water sandwiching).
Non-condensing heaters from Noritz are using thicker copper pipes for its heat exchangers, which brings longer service life and increased thermal efficiency.
Condensing models on the other side are equipped with the dual heat exchangers, which combines the thick copper pipes and stainless steel.
Condensing technology allows water to get more heat from the flue gases, so Noritz hot water heaters can increase its performance and lower the temperature of the exhaust gases and use cheaper PVC pipes.
This series also brings an incredible 11 gallons per minute of hot water.
Like other manufacturers, Noritz is providing endless hot water, while the Turbo-flow feature brings a higher flow rate.
Quick-Connect is available on models such as NR981, NRC111, and NRC98, which brings even more hot water for one home. This feature allows two identical models to connect, combining the power and work as one.
There is also a larger Multi-system that can be used to link up to 24 units. These units are hooked up to a single controller so that this system can work as one system.
Troubleshooting Noritz tankless water heaters is easy as the unit uses an advanced control and diagnostic system available on the built-in controller (some models). Some of the error codes can be found in this article.
As it can be seen from the above review and detailed category review, the Noritz manufacturer makes tankless water heaters for almost any type of the house; new or old, small or large, and for any budget, economy mid-efficient models and advanced, expensive ultra-efficient condensing heaters. The common benefits are the endless hot water supply, small size, wall-hung installation, low NOx emission, easy use and control, and lengthy warranty.
