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.

We just had a gas fireplace installed by Cozy Comfort Plus. What an incredible and seamless process this was - beginning to end.
We met with a few companies, and loved the professionalism and communication with Brian. He was thorough in his explanations, took his time to answer all our questions. We were so impressed that we knew right away this was a company we wanted to work with.
The installation was seamless! A team of three people (Jason, Amir, and Hamid) came on time and got straight to work. They were friendly, efficient, and left the space spotless!
Had we known that switching from a wood fireplace to a gas one was this easy, we would have done it years ago!
We would highly recommend Cozy Comfort Plus to anyone wanting to install a gas fireplace!!!
So happy we did our research and ended up working with these guys!

Greg LindsayMy furnace broke mid February and from the first call Cozy Comfort Plus exceeded my expectations and it was the best customer service experience I've had in a very long time. They had someone here within two hours who very knowledgeable and gave me several options. I ended up deciding to replace my furnace and they had it done the next day. From my first contact on the phone, to the technician to the installation staff they were all professional, responsive and truly a pleasure to work with. In a little over 24 hours the heat was back on and at a very fair price.
I cannot recommend them highly enough as it's a stressful time when your furnace goes mid February. They even submitted the rebates before I had a chance to call them the next day!! All I can say is WOW.
