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

Provides longer life expectancy as they are highly resistant to corrosion and erosion compared

Reduces minerals deposits.

New metal fiber burner is designed to deliver a consistent air/gas mixture improving combustion efficiency.

Low NOx Emissions (≤ 20ppm)

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 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.

Intelligent Preheating Technology

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