Navien’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

Diagram of Navien stainless steel heat exchangerNavien 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!

Shower, washer, and bathtub

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

Exo Pre-mixed BurnerEco 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.

Comparison of a tank water heater and a NR-180Space 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.

③ Three-phased, Pre-Mixed Burner
Controls flame by pre-mixing optimal ratio of gas and air before combustion, reducing emissions and enhancing heat efficiency.

④ Leak Detector
Built-in leak detector prevents damage to water heater as well as personal property.

⑤ Air Intake Filter
An air intake filter prevents foreign substances, such as dust or insects, from entering the system, freeing the burner from elements that would normally cause unstable combustion or energy inefficiency.

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 98-12

With the Eternal hybrid water heater, you get endless hot water without sacrificing water pressure. Its compact stainless steel design is up to 98% efficient, durable, and leaves almost no carbon footprint.


What is a hybrid water heater?

Diagram of a hybrid water heaterTank + tankless = Eternal. The Eternal provides endless hot water like a tankless, but has about 2 gallons of storage inside. Why is storage important? The buffer storage means hot water is ready when you need it. You do not have to wait for the water to heat up and waste energy when the hot water is not being used. Plus, you do not lose water pressure when running multiple fixtures and appliances. Therefore, you get the benefits of a tank and a tankless without having to worry about running out of hot water.

 How does it work?

With Eternal’s unique patented counter flow design, cold water enters from the bottom while heat is pushed down from the top through radiating transfer pipes. As the water flows through the unit, heat is pushed in multiple directions to maximize the transfer of energy. The end result is a small, efficient heat exchanger that can replace multiple tanks and supply endless hot water.

Can it support multiple applications?

All of the Eternal hybrid water heaters can support multiple applications. You can run the dishwasher, shower, and do the laundry at the same time. Select the Eternal that is right for you.

Does it have advanced features?

The Eternal has a digital display screen that allows you to adjust the temperature with ease. You can turn the hot water temperature up in the winter and turn it down in the summer. When you go on vacation, you can even turn the water heater off so you do not waste energy. The Eternal also has an optional remote control that allows you to change the temperature from a more convenient location.

Will it save time & water?

Eternal is compatible with most recirculation systems, whether it’s a dedicated return line or under-the-sink retrofit pump. The built-in reserve tank within the heat exchanger makes instant hot water possible. Sold separately.

Is it easy to install and maintain?

The Eternal water heaterThe Eternal must be installed by a licensed contractor with plumbing expertise. Since the Eternal features standard water connections on top, the unit can sit in the same space as a tank. It’s small size and flexible design allows you to put the Eternal indoors, outdoors, wall mount or place it on the floor. Due to its patented self-cleaning design, the Eternal does not need a costly annual heat exchanger flushing which is often required for tankless.

Will it help me save money?

energystar[1]The Eternal is an Energy Star appliance and is up to 98% thermal efficient which means for every dollar you pay for fuel, 98 cents is transferred to heat. Over time, the high efficiency can save your family time, energy, and money. Since the Eternal is an ENERGY STAR appliance, it qualifies for available government and/or local utility rebates.

What type of warranty and support does Eternal offer?

Eternal comes with a 15 year residential / 5 year commercial no leak warranty.
