Core Technologies
Comfort Flow
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).
EZ Nav
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

Existing installations may require the purchase of a new main PCB and front control panel.

NaviLink & NaviLink Lite make it easy to communicate with your Navien systems anywhere internet service is accessible. The NaviLink system attaches easily to any new or existing* Navien tankless water heater, combi-boiler or boiler. NaviLink Lite is great for single residential units and magnetically mounts to the side of the unit or can easily be mounted on the wall. Also, NaviLink Lite does not require external power.
