Exclusive built-in recirculation system included on all NPE-A models.
Navien ComfortFlow® is the first and only system that incorporates a built-in insulated buffer tank and recirculation pump.
The buffer tank eliminates the “cold water sandwich” effect and issues of minimum flow rates commonly found in other tankless water heaters. The recirculation pump saves on water bills by reducing the time to get hot water. When activated, the optional ComfortFlow mode results in additional energy usage.
ComfortFlow® recirculates hot water through supply lines, eliminating wait time for hot water.
Front Panel Control Center
Self-diagnostics.Cascade up to 16 units withNavien Ready-Link® technology.
Common vent up to 8 units
Optional Wi-Fi remote control system
NaviLink makes it easy to communicate with your Navien systems anywhere internet service is accessible. The NaviLink module attaches easily to any new or existing* Navien NPE Series tankless water heater, NCB-E Series combi‐boiler and NHB Series boiler.
Optional hot water activation
system for all NPE-A units
At the push of a button, the Navien HotButton hot water system activates the internal recirculation pump and gas-fired burner to heat water in the supply lines to provide hot water whenever it’s needed.
The H2Air Kit utilizes the NPE-A pump to circulate the hot water for the hydronic air handler. This removes the need to purchase an additional circulator for the heating system.
Designed for retrofit and new construction, the Navien H2Air Kit™ includes an add-on controller to integrate space heating and DHW between any NPE-A series tankless water heater and a hydronic air handler.

Brian is very easy to work with, his advise about which gas stove to go with was excellent and my parents ending up going with the high-end Regency model. His installers were very good and were easy to talk to about the job and they did an excellent job. I like it when a contractor works with their customers and cares about their company to back up the work done. I highly recommend them and a special thank you to Brian who runs an excellent company! My parents are extremely happy and can't wait on those cold nights to go by to feel the warm heat of their new stove.
