Navien's next-generation condensing tankless technology is designed to simplify every installation and offer the best hot water experience. It eliminates the tankless obstacles of past, making it an ideal solution for tank replacements. Simle retrofit, exclusive ComfortFlowTM technology, ultra high condensing efficiency and now field gas convertibility all combine to make the new NPE series easily the best choice in tankless.


Utilizes Existing 1/2" Gas Line
The NPE is the first tankless system that can utilize a home's existing 1/2" gas line, for lengths up to 24feet.

2" PVC Venting
Low exhaust gas temperature allows for use of PVC, CPVC and Polypropylene vent systems, significantly reducing installation cost and hassle. The system can use 2" venting for up to 60feet, often letting the installer run a flue through the existing chase without requiring additional holes.

Field Gas Convertibility
The NPE's negative pressure gas valve and Dual Venturi system allows for easy field convertibility from Natural Gas (NG) to Propane (LP) operation.

Comfort Flow Technology
Eliminates "cold-water sandwiches" and issues of minimum flow rate. An insulated buffer tank and recirculation pump accelerates hot water delivery.

Intelligent Preheating Technology
Recognizes hot water usage patterns to intelligently provide hot water when needed.

Ultra Condensing Efficiency
Navien's condensing technology delivers cooled exhaust gas and high-performance. (EF .95)

Dual Stainless Steel Heat Exchangers
Two stainless steel heat exchangers provide longer life expectancy, as they are highly resistant to corrosion compared to copper heat exchangers.

Front Panel Command Center
A user-friendly interface on the front of the unit makes it easy to set up the NPE, run diagnostics and view essential system information.

High Altitude Operation
The NPE is designed to operate up to 10,000 feet, ensuring maximum performance in any region.

Outdoor Vent Cap (Optional)
NPE is designed for outdoor installation.

So much advanced technology in such a compact unit.
The NPE is a fully integrated system, designed to provide a high-performance hot water experience.

Simpler inside and out.
In comparison to other units the Navien NPE is designed with simplicity in mind.
