About Navien Water Heaters

In 2006, Navien, Inc. was established to open new markets in the United States and Canada for parent company KD Navien. Navien has since become one of the fastest growing companies in the home comfort sector in North America, providing condensing tankless gas water heaters and condensing combi boilers. Navien's products possess state-of-the-art technology, high efficiency and reliable quality, making it the leader in the marketplace for tankless technology.
Navien has achieved international recognition for its sophisticated engineering and robust designs. Backed by more than thirty years of experience with advanced water heating technology, Navien will continue its mission to provide high quality products that are beneficial to both customers and the environment.

Navien’s Premium Tankless Gas Water Heaters are available for both residential and commercial use. Unlike traditional tank water heaters, Navien tankless heaters provide an endless supply of hot water any time you need it. So what sets Navien tankless heaters apart from other water heater products? Navien specializes in condensing tankless water heaters and this condensing technology gives the brand’s units unparalleled efficiency. In fact, Navien’s water heaters boast an average of 0.98 efficiency factor. This is a dramatic improvement from traditional tank water heaters that only have a 0.55 energy factor. Meanwhile, the average tankless water heater has an 0.82 efficiency grade. Although there are other brands that are currently manufacturing condensing tankless water heaters, their average energy factor only reaches 0.95, which is obviously way below Navien’s efficiency grade.
For the average homeowners, this superior thermal efficiency translates to lower costs in energy bills. Aside from its revolutionary condensing technology, the Navien tankless water heater is also equipped with ECO Premixed Burners which dramatically cut down the heater’s NOx and CO emissions by as much as 75%. This Eco Burner Technology makes the Navien tankless water heater one of the most environmentally friendly tankless heaters in the market.
