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.

I have needed immediate service and repair for the Heat Pump in my Condo in Mississauga three times over the last 8 years. Every time during the heat wave in the summer, and also Ice storm in the winter. Cozy Comfort Plus was referred to me by a family member. Since then Cozy Comfort Plus has always been the place for me to go to for professional and great technical service and repair, even for maintenance on my Gas fire place. As I needed to keep my tenants happy and satisfied. They helped me save thousands of Dollars, by recognizing the problem and replacing the faulty part on a cheap Heat Pump installed by the original builder. Cozy Comfort Plus truly stand to their name. I have referred them to my elderly parents also living in a Condo and they had the same great experience I did. Their technicians are experienced, professionals and extremely customer friendly. In all occasions, they treated it as if their own. Thank you Cozy Comfort Plus

Amir VaghariWe've had Cozy Comfort Plus over at least a couple of times to instal and maintain our furnace over the years for our place in Mississauga. They have gained our trust and exceeded our expectations as customers. They repaired our heat pump that has been working exceptionally since their visit. They also fixed our AC on another occasion. These guys are the best in the business and honestly such wonderful people. If you were looking for a trustworthy organization with integrity, I would highly recommend contacting Brian and team at Cozy Comfort Plus. I'm sure these people will take great care of you, just as they did for us!

Martin SykesCozy Comfort Plus Inc. installed a new high efficiency furnace in our house two years ago and it has been operating perfectly ever since. Their service was straight forward, reasonably priced and good value for money. They even walked us through the complicated rebate program that was hard to understand without being involved in the industry.
I would highly recommend them for your next heating and cooling needs.
