The Ultimate in Energy Efficiency with Hi-Tech Comfort
Endless Hot Water Supply
Navien Condensing tankless heaters over safety and an unlimited amount of hot water supply. Consumers love the endless supply of hot, soothing water!
Industry's Highest Energy Efficiency Rating - 98%
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. Navien’s Condensing Tankless offers the highest gallons-per-minute (GPM) when comparing input BTUs.
Remote Control
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.
Built-in Circulation System
The built in circulation systems allows for no minimum flow rate with internal circulation mode. It will also minimize hot/cold/hot stacking, the so called “Cold Water Sandwich”, and save on installation cost with the circulation pump and buffer tank factory installed.
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. Navien Condensing 98% has become more eco-friendly by dissolving NOx in condensed water to neutralize the alkaline sewage in your house, improving water quality.
Extended Lifecycle
Navien utilizes dual stainless steel heat exchangers, providing 3.8 to 4.5 times longer life-expectancy and erosion resistance over the copper heat exchangers used in other brands. Navien’s stainless steel heat exchanger operate with relatively low water temperatures, minimizing damage from hard water conditions and maintains a high efficiency levels.
PVC Venting & Easy Installation
The high efficiency of Navien’s Condensing Tankless results in lower exhaust temperatures, allowing for the use of 3” PVC.
Optimal and Stable Operation
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.
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.
Space Saving
Navien’s condensing tankless water heater occupies approximately 90% less space than a tank-type water heater. In addition, a Navien mounts on your wall freeing up valuable floor space. |
