Models: NPE-240A, NPE-210A, NPE-180A
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’.
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.
Eliminates cold water sandwich.
Saves water with the reduced time to get hot water.
Saves money with built-in recirculation system.
Intelligent pre-heating function.
Offers the ultimate hot water experience
Navien’s units have built in controls for multi-unit system allowing easy setting.
No extra control boards are required, reducing installation costs.
Easy wiring between units and easy setting of the parent and child for multi-unit system.
16 units can be linked as one group and cascade as many groups as you need.
Cascading allows for added redundancy insuring on-demand hot water in all situations.
Small and compact wall-hung design allows multi-unit system even in a confined area.
Used for hotels, schools, hospitals, beauty shops, restaurants, health centers, and more.
