Navien NPE-180A2 - Condensing Tankless Water Heater - 150,000 BTU

The Navien NPE-180A2 is a high-efficiency condensing tankless water heater designed for residential and light commercial use. With a capacity range of 10,000 to 150,000 BTU per hour and a Uniform Energy Factor of 0.95, it delivers powerful performance while minimizing energy waste. The unit provides a maximum flow rate of 8.4 GPM at a 1.7 °C temperature rise, making it suitable for multiple simultaneous hot water demands. Compact and wall-hung, it installs easily indoors or outdoors and supports field conversion between natural gas and propane.

Equipped with Navien’s dual stainless steel heat exchangers and a built-in recirculation pump, the NPE-180A2 offers exceptional durability and faster hot water delivery. It features the EZNav™ multi-line control panel with integrated HotButton™ for user-friendly control, and it supports cascading and common venting with up to 12 units. Approved for 5.1 cm or 7.6 cm venting materials, it supports long vent runs and uses a 1/5.1 cm gas line up to 731.5 cm. With ultra-low NOx emissions and multiple built-in features, the NPE-180A2 meets a wide range of installation needs with high efficiency and flexibility.

Navien NPE-A2 simply a smarter hot water system for today's life styles

Navien...the proven leader in condensing tankless,  makes it even easier to install and set up  with the new NPE-A2 series

Built-in recirculation system

Navien’s patented ComfortFlow ®  system is the first to include a buffer tank, recirculation pump and fine-tuned controls into a tankless water heater, resolving the cold-water sandwich effect* and issues of minimal flow rates commonly found in other tankless water heaters.

* The “cold-water sandwich effect” is the undesired introduction of cold water into the hot water supply line on occasions of frequent on/off operations. (Measure Guideline: Transitioning to a Tankless Water heater, DOE, Sept.2012).

  The built-in recirculation pump allows the NPE-A2 to recirculate water either through an external recirc line or through existing supply lines while using NaviCirc®, without the need for external pumps or controls.

 

 

Multi-line control with built-in intuitive software 

Navien’s new backlit EZNav™ control panel uses simple text and icons to make set up, operation status and troubleshooting faster and easier than ever before.

• Self-diagnostics.
• Displays temperature and water flow rate.
• Displays status of cascade operation.
• Convertible display from °F to °C.
• User Friendly Interface.
• Easy setup.
