Ultra Condensing EfficiencyNavien’s condensing efficiency boasts the industry’s highest efficiency. Customers can take advantage of the low annual operating costs and receive the best value and payback, compared with conventional tankless or tank-type water heaters.

Extended Lifecycle
Navien utilizes dual stainless steel heat exchangers, providing a longer life-expectancy and more resistance to erosion than copper heat exchangers used in other water heaters. Navien’s stainless steel heat exchangers operate with relatively low water temperatures, minimizing damage from hard water conditions and maintains a high efficiency level.

Endless Hot Water Supply
Navien’s Condensing Tankless Water heaters offer an unlimited supply of hot water to meet a home’s unending demand for hot, soothing water!

Easily Installed PVC Venting
The high efficiency of Navien’s Condensing Tankless Water Heater results in lower exhaust temperatures, allowing for the use of 3″ SCH 40 PVC venting.
PVC venting offers a significant cost savings when compared with other venting materials.
PVC venting is lightweight and easily slides together, reducing installation time and making it easy to run a 100 feet of venting.- * Each elbow deduct 5′ off of venting length
Eco Navien Technology
Navien’s condensing technology uses less gas than conventional water heaters, resulting in less CO2 emissions.
The Eco Pre-mixed Burner dramatically reduces NOx emission levels, making it the lowest emission levels in the industry.
Each Navien Unit Installed Equates to 31 Cypress Trees.A Navien Condensing water heater reduces up to 964 lbs of CO2 per year compared to a conventional water heater, and up to 324 lbs of CO2 per year compared to a tankless water heater.

Optional Circulation Pump and Mini Buffer Tank (Model “A”)
No minimum flow rate required with optional internal circulation mode
minimize hot/cold/hot stacking, the so called “Cold Water Sandwich”
Save installation cost with optional circulation pump and buffer tank- The Ready-Link® Cascading System can combined “A” models units and non “A” model units together to save money on installation costs and conserve water.
Space Saving Design
Navien’s condensing tankless water heater’s compact, wall mount design occupies approximately 80% less space than a traditional 50 gallon tank-type water heater*. Navien’s compact design adds free space that can be used to store other house hold items.

Advanced Technology
① Enhanced Safety with Dual Microprocessors
Navien’s two microprocessors offer better control and safer operation by continuously cross monitoring each other’s performance to assure proper operation at all times.
These two microprocessors not only control the burner for ideal combustion but also maintain the steady hot water temperature.

② Optimal and Stable Combustion with APS and GPS
APS (Air Pressure Sensor) maximizes combustion efficiency by sensing and controlling the air required for optimal combustion even in high-wind locations and installations with long vent runs.

GPS (Gas Pressure Sensor) offers stable combustion by sensing gas pressure and controlling the fan speed to maintain optimal combustion, even under a wide range of gas-pressure changes.
Remote Control (NR-10DU)
Advanced water heater diagnosis capability and error feedback
Touch activated backlight function and Easy-to-Use button type control
Built-in recirculation timer for water and energy savings
Key-pad lock button prevents inadvertent temperature changes
Temperature adjustment in 1°F increments between 98-120°F
