    Ultra Condensing Efficiency

    • Boasts one of the industry’s highest ratings of 0.96 DOE energy factor.
    • Low annual operating costs and the best value and payback.
  • Two Stainless Steel Heat Exchangers

    Extended Lifecycle

    • Dual stainless steel heat exchangers provide longer life expectancy and more resistance to erosion than copper heat exchangers used in other water heaters.
  • Low NOx Emissions (≤ 20ppm)

    Navien Technology is Eco Friendly

    • The Eco Pre-mixed burner dramatically reduces NOx emission levels.
    • Boast the lowest emission levels in the industry.
    • Each Navien unit installed equates to 31 cypress tress.
  • 2” PVC, CPVC, Polyprophylene Venting Up To 60’

    Inexpensive PVC venting solution

    • Lower exhaust temperatures allow for the use of 3” SCH 40 PVC venting.
    • Offers significant cost savings when compared with other venting materials.
    • Reduces installation time and makes it easy to run a 100 feet of venting.
  • Better Adaptability to Gas System

    Enhanced Safety with Dual Microprocessors

    • Two microprocessors offer better control and safe operation.
    • Not only control the burner for ideal combustion but also maintain the steady hot water temperature.
  • Field Convertible

    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.
    • GPS (Gas Pressure Sensor) offers stable combustion by sensing gas pressure and controlling the fan speed to maintain optimal combustion.
  • Ultra Condensing Efficiency

    Space Saving Design

    • The wall mount design occupies approximately 80% less space than a traditional 50 gallon tank-type water heaters.
  • ComfortFlow

    • Eliminates minimum flow rate requirement with optional internal circulation mode.
    • Minimize hot/cold/hot stacking, the so called “Cold Water Sandwich.”
    • Saves water with the reduced time to get hot water.
    • Saves on installation costs with built-in circulation pump and buffer tank.

Navien’s Ready Link System is the best alternative for large volumes of hot water. With its easy venting and installation, unlimited Navien Water Heaters can be set up as one system. Unlike tank-type water heaters, sudden hot-water cutoffs can be avoided.

  • Abundant Hot Water Supply

    16 units can be linked as one group within the system and several groups can be linked-up into one system.
  • Energy Saving

    Industry’s most efficient multi-unit system with an exceptional rating of 0.96DOE energy factor.
  • Easy Wiring Connection

    Simple wiring link without complicated communication cables and controllers.
  • Easy Ventilating

    Built in APS for longer vent pipe.
  • Low Maintenance Cost

    Even if one unit of the system fails, the rest will operate without any problems.
  • Full Modulation System

    Units activate individually as the demand for hot water increases.
