About Navien Inc

Navien Brand Logo

One of the reasons that Navien is not as well-known as some of its competitors is due to the fact that the company hasn’t been around as long. They were founded in 2006. Despite their short stint in the industry, they’ve already managed to make an impact on the market. Of course, the group’s parent company is KD Navien, which has been working with water heating and boiler technology for over 35 years! So, they definitely know a thing or two about such technologies and how to satisfy clients throughout the world.

The parent company, KyungDongNavien, was founded in 1978. In 1988, the company made history by developing the first highly efficient and eco-friendly condensing boil in Asia! Now, they’re bringing their products to North America.

Navien’s Technologies

In order to figure out, whether or not a Navien tankless water heater is right for you, it is essential to figure out precisely how the company’s technologies work. Unlike the traditional, storage water heaters, these units are capable of providing the user with hot water on demand. And these units only activate once you’ve turned on the water tap. This helps to eliminate the need to constantly heat up and store hot water, which will ultimately lead to a decrease in your electricity bill. If you’re a fan of hot water and absolutely despise running out, you’ll love a Navien tankless model.

Navien Warranty


When taking the time to explore Navien’s portfolio of water heaters, you’ll want to pay close attention to the company’s warranties. Navien does provide the consumer with a lengthy warranty, but the specifics vary substantially from one water heater model to the next. The majority of residential water heaters from Navien will come with a 1-year warranty on labor, 5-year parts warranty, and a 15-year or 5-year warranty on the heat exchanger. Checking the manual or specifications of your model is recommended.
