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.
