Navien NPE-180A




  • ½” gas pipe capable up to 24’
  • Field convertible gas system
  • Ultra condensing efficiency
  • Dual stainless steel heat exchangers
  • Low NOx emissions (≤ 20ppm)
  • SCH 40, 2” venting up to 60’
  • Cascading capable

Ultra Condensing Efficiency

  • Navien’s Condensing Technology offers the high efficiency.
  • Money and energy savings over a tank type water heaters and traditional water heaters.

Two Stainless Steel Heat Exchangers

  • Provide longer life expectancy as they are highly resistance to corrosion and erosion compared to copper heat exchangers.
  • Reduce minerals deposits.

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” 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.

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

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

Less Water Press 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.

Intelligent Preheating Technology

  • Recognizes hot water usage patterns to intelligently provide hot water when needed.
