The Ultimate in Energy Efficiency with Hi-Tech Comfort

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 system also has the highest gallons-per-minute (GPM) when comparing input BTUs.

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.

Advanced Technology

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

  1. 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.
  2. 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.
