EZNav™ multi-line control with built-in intuitive software

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.

Cascading up to 32 units and common vent up to 12 units

Cascade up to 32 units with Navien Ready-Link® technology.

With Navien's Ready-Link® cascading technology, when a unit gets up to 80% capacity the next unit will turn on to help meet requirements. The flow on demand ratio will continue until all 32 units are generating hot water as needed. The Navien cascading system also balances out the workload of each unit for longer life.

Common vent
up to 12 units

Building penetrations are reduced with Navien's common venting feature.
