ComfortFlow®  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.

EZNav™ 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.

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.
