Navien NPE-210S Premium Condensing Tankless Gas Water Heater Features

  • Ultra Condensing Efficiency

    Ultra Condensing Efficiency

    • Navien’s Condensing Technology offers the high efficiency.
    • Money and energy savings over tank type water heaters and traditional water heaters.
  • Two Stainless Steel Heat Exchangers

    Two Stainless Steel Heat Exchangers

    • Provides longer life expectancy as they are highly resistant to corrosion and erosion compared to copper heat exchangers.
    • Reduces minerals deposits.
  • Low NOx Emissions (≤ 20ppm)

    Low NOx Emissions (≤ 20ppm)

    • New metal fiber burner is designed to deliver a consistent air/gas mixture improving combustion efficiency.
    • Result in less acid rain and less green house effect.
    • Comply with SCAQMD 1146.2 strict NOx emissions standard.
  • 2” PVC, CPVC, Polyprophylene Venting Up To 60’

    2” PVC, CPVC, Polyprophylene Venting Up To 60’

    • 2” venting option allows for a flue to be pulled through the existing vent.
    • 3” vents can be used up to 150’ with standard 2” x 3” adapters.
  • Better Adaptability to Gas System

    Utilizes Existing 1/2″ Gas Line

    • The negative pressure gas valve and fan with dual venturi operation allows for better adaptability to low gas pressure applications.
    • Makes it possible for the NPE to be installed ½” gas lines up to 24’.
  • Field Convertible

    Field Convertible

    • NPE models allow for easy convertibility from NG to LP.
  • Ultra Condensing Efficiency

    Less Water Pressure Drop

    • Simple modular for water path minimizes water pressure drop.
    • Modular design for water path make maintenance easier and service can be performed easily in the field.
