Navien managed to expand its operations to the United States and Canada in 2006. The company has gone forward to become one of the most reputable producers of several home comfort products including tankless water heaters. Here is the Navien tankless water heater reviews for your better understanding which tankless water heaters are best.

Why Should You Choose Navien Tankless Water Heaters?

Navien’s Tankless Water Heaters are available for both commercial and residential use. Unlike the traditional tank-type water heaters, Navien tankless water heaters usually provide an endless supply of the hot water at any time you require it.

Therefore, what actually sets the Navien tankless water heaters apart from the other water heater products? Navien normally specializes in producing condensing tankless heaters and the condensing technology has given their units unparalleled efficiency. As a matter of fact, Navien’s tankless heaters boast of an average efficiency factor of 0.98. This is a great improvement from the traditional tank-type heaters that only had an energy factor of 0.55. Meanwhile, average tankless water heaters have an efficiency grade of 0.82. Although there are still other brands that are presently manufacturing condensing water heaters, their average energy efficiency only reaches 0.95 which is clearly way below the Navien’s efficiency grade.

For average homeowners, such superior thermal efficiency usually translates to low costs when it comes to energy bills.

Apart from its revolutionary condensing technologies, the Navien water heaters are also equipped with the ECO Premixed Burners that dramatically cuts down the heater’s CO and NOx emissions by as much as 75 percent. The Eco Burner Technology normally makes the Navien water heaters to be among the most environmentally friendly heaters on the market today.

The Comfort Flow Technology is also another feature which gives Navien tankless heaters an edge over other tankless water heaters in the market. Most tankless water heaters usually have the “cold water sandwich problems”, where supply of the hot water flows inconsistently thus resulting into short bursts of the cold water in between the flow of hot water. With Navien’s buffer tank and recirculation pump, the cold water sandwich phenomenon doesn’t become a problem anymore.
