Tankless Water Heater - Navien
Navien tankless heaters provide an unlimited amount of hot water
at a steady temperature,
whenever you need it, for as long as you need it. Below is a
list of benefits of Navien tankless water heater:
Ultra Condensing Efficiency
Built-in Circulation Pump with Mini Buffer
Tank. “A” Models Only
Eco-Navien Technology
Extended Lifecycle
Easy Venting
Space Saving
Advanced Technology
Remote Control
Navien's 98 Ready-Link® Cascade System
Navien Condensing 98% Tankless Sizing
Exhaust Vent Pipe Materials

| Ultra Condensing Efficiency |
|
|
|
Because this product boasts the industry's
highest efficiency, rating (98%) means
customers can cash in on low annual operating
costs as well as receive the best payback, compared with conventional tankless
or tank-type water heaters. Navien's Condensing 98% Tankless also enjoys the
highest gallons-per-minute (GPM) when comparing input BTUs.

| Built-in Circulation Pump with Mini Buffer
Tank. “A” Models Only |
|
 |
|
- Delivers hot water to fixtures quickly resulting in
water conservation.
- No minimum flow rate: get hot water even at very
low flow rates of 0.1 or 0.2 GPM
- Eliminates any hot/cold/hot stacking, the so-called
"Cold Water Sandwich".
- Saves additional money and time by eliminating
the pump purchase cost and on-site installation
costs.
- Prevents heat exchanger from freezing.
If over half of water heaters are 'A Series models' in
Ready-Link® Cascade System, 'Non-A Models' can
be used as part of multi-unit systems. This allows
hot water circulation system as well as water
savings with low costs.

|
| Eco-Navien Technology |
|
|
|
Navien utilizes condensing technology, which uses
less gas, resulting in less CO2 emissions than
conventional water heaters.
Navien's ECO Premixed Burner not only dramatically
reduces NOx emissions but also boasts the industry's
lowest level of emissions .
Partly dissolved NOx in condensed water neutralizes
the alkaline household sewage, improving water
pollution.
|
| Extended Lifecycle |
|
 |
|
Navien utilizes dual stainless-steel heat exchangers, providing 3.8 to 4.5
times longer life-expectancy and superior resistance to corrosion over the
copper exchangers used in other brands. Navien heat exchangers operate with low-to-mid temperature water,
minimizing possible damage caused by lime build-up, making the whole
unit more efficient.

|
|
| Easy Venting |
|
The high efficiency of Navien's Condensing 98% Tankless results in lower exhaust temperatures, allowing for the use of PVC or other plastic venting materials.
- Plastic venting offers a significant savings
in cost and makes installation a breeze.
- Three-inch PVC venting runs up to 100 feet with six elbows;
allows for installation up to and above an altitude of · 4,500 feet,
without additional devices.

|
|
| Space Saving |
|
|
A Navien occupies approximately 90% less
space than a tank-type water heater. In addition,
a Navien mounts on your wall freeing up 100% of
traditionally lost floor space.

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.
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.
Triple-Layered, Pre-Mixed Burner
Controls flame by pre-mixing optimal ratio of gas and air before combustion,
reducing emissions and enhancing heat efficiency.
Leak Detector
Built-in leak detector prevents damage to water heater as well as personal
property.
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 |
- Advanced water heater diagnosis capability and error feedback.
- Touch activated banklight 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 1 ˚F increments.

|
| Navien's 98 Ready-Link® Cascade System |
Navien's 98 Ready-Link® System is the best alternative for large volumes of hot water.
With its easy wiring connection, up to 98 compact-sized Navien Water Heaters can be set up as an one system.
Unlike tank-type water heaters, sudden hot-water cutoffs can be avoided.

|
| Navien Condensing 98% Tankless Sizing |
Navien units are sized to meet the number of fixtures that a home owner expects to
run simultaneously. Because of the varying ground water temperatures across North America
and across seasons, the flow rates will change slightly depending on the region you live,
but typically, Navien tankless units can provide either
2 or 3 major fixtures simultaneously without problem on the coldest winter days.
Right Model For You

| | Exhaust Vent Pipe Materials |
All Navien water heaters are Category IV appliances;
NOTE: Plastic vent can be used in all cases EXCEPT when the
incoming (or recirculation return) water temperatures exceed 160°F (70°C).
IF you set the water heater at a temperature higher than 160°F (70°C) AND
you are running an external recirculation loop or a combination heating
system, you MUST use the Navien stainless steel venting or any 3" venting
system approved for use with Category IV appliances (typically Type BH
Special Gas Vent approved to UL1738-S636)**
