Industry’s largest turn down ratio in the NHB-150 providing ease of installation with multiple zones while maintaining high operational efficiencies.
As the leader in condensing technology, Navien has already reinvented the water heating industry with the award-winning NPE tankless water heaters and the NCB combi-boilers. The new NHB boiler series is the next in line of innovations from Navien. All NHB boilers have Navien’s advanced burner system, an industry-leading AFUE of 95% and turn down ratios up to 15:1.
Now available in four sizes NHB 55, NHB 80, NHB 110 and NHB 150.

NHB Integrated control
The integrated control provides industry-leading options and features in the boiler operation parameters, including:
pacity.Manifold Kits
Navien’s Manifold kits are ideal for hydronic space heating applications. With these manifolds, we have done the piping work for you. Both primary and secondary loop manifold kits are designed to work on all NHB models for fast and clean installations. All you need to add is your own appropriately sized pump
Navien’s two largest condensing boilers, NHB-110 and NHB-150, can be cascaded and common vented
With our cascading technology, when a unit gets up to 80% capacity determined by the supply and return temperatures, the next unit will enable to help meet the hydronic space heating requirements.
This hydronic space heating requirement and demand ratio will continue until all units are generating the needed hydronic space heat up to the maximum cascaded capacity. The Navien cascading system also balances out the workload of each unit for longer life. The NHB is dual certified for single and 2-pipe venting applications.
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.

We purchased a gas insert for our home from the Cozy Comfort Plus. The whole process was super smooth and easy from the very beginning. Brian was very knowledgeable and professional. He patiently guided us through different options we had. The installation crew were also super friendly but at the same time professional and serious about their work.
I would definitely recommend them to anyone who is looking for a satisfactory experience.
Jon ConwayWe are so happy with the service, support and product that we received from Cozy Comfort Plus. Brian was incredible to work with, he took the time to understand what we were looking for and helped us with the designs and what the best fireplace for us might be. He is extremely easy to work with, very easy to communicate with and so fast and responsive!
Everything happened exactly on schedule and as planned. It was a well oiled machine!! The crews that were here to build everything were super friendly, kind, courteous and knowledgeable.
Highly highly recommend to all 😀👍

Andrew P.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!
