Noritz advanced features and difference

What I personally like on Noritz tankless water heaters are the advanced 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 almost all parts are built by this company, no outsourcing.

High energy efficiency

Noritz tankless water heaters can perform with the 83-97% energy efficiency, making them environment friendly or "green", great energy savers and some Energy Star approved.

Dual flame burner

Dual flame burner is one of the latest technologies used in Noritz water heaters, while most of the competitors utilize the single flame burners. This Noritz' superior technology allows greater performance, efficiency and cleaner gas combustion.

Powerful and clean

Even with the higher water flow rate, dual flame burner increases the heating output. Tankless models with the two rows of burners are not only powerful but they are good on the environment as they produce less greenhouse gases and provide hot water with less fluctuation in the temperature (less cold water sandwiches).

Heat exchanger

Non-condensing heaters from Noritz are using thicker copper pipes for its heat exchangers, which brings longer service life and increased thermal efficiency.

Condensing technology

Condensing models on the other side are equipped with the dual heat exchangers which are the combination of 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 amazing 11 gallons per minute of hot water.

Turbo-flow

As other manufacturers, Noritz is providing an endless hot water while the Turbo-flow feature brings higher flow rate.

Quick-Connect

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 be connected, combining the power and work as one.

Multi-system

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 this system can work as one system.

Easy troubleshooting

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.

Summary

As it can be seen from the above review and detailed category review, 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 heaters.The common benefits are the endless hot water supply, small size, wall-hang installation, low NOx emission, easy use and control and long warranty.
