Noritz Water Heater
It’s very important to underline that Noritz tankless water heaters are extremely durable, lasting longer than traditional tank-type water heaters, and requiring little maintenance over its lifetime. They heat water on demand rather than storing a limited amount of hot water in a tank. It seems that there is a virtually endless supply of hot water. For instance, the Noritz water heater can support up to 4 shower heads.
There are many different reasons to purchase one of the heaters of the brand Noritz. The biggest components to a tankless water heater are the burner and heat exchange, the heart of the system. Instead of using just one flame burner, Noritz utilizes two burners instead, not only heating the water running through the system faster, but the second row also captures and burns and left over gases that have escaped from the first, reducing emissions, stabilizing water heat variations, and boosting flow rate.
In addition, they use a commercial grade heat exchanger, which is the main component that takes most of the abuse from the heater.
Installation
Venting is probably the most important part of a tankless heater installation. There are many good flexible gas piping systems that can make this job simple and limit the number of joints and installation time of the new gas line. Read and obey your owners manual and manufacturers installation instructions. However, you should keep in mind that every installation is unique to a home. The Noritz should be installed by a Noritz qualified installer.
