NHB‑H
NHB-H Series
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-H combi-boilers. The new NHB-H boiler series is the next in line of innovations from Navien. All boilers have Navien’s advanced burner system, an industry-leading AFUE of 95% and turndown ratios up to 15:1.
Now available in four sizes NHB-55H, NHB-80H, NHB-110H and NHB-150H.

Industry’s largest turndown ratio in the NHB-150H minimizes short cycling and provides better reaction to changing demands throughout the year.
With Navien’s new PCB design you now have the ability to connect and control a boiler pump, 3 zone pumps or 3 zone valves, all integrated in the unit.
Navien’s new backlit control panel is simple and intuitive to use with its color‑coded plain text display, and an innovative click wheel for easy navigation through setup, operation, diagnostics, and more.
This system matched stainless steel manifold kit is just another high-quality accessory to help make your installation faster and easier. The kit includes the space heating supply isolation valves, space heating return isolation valves, PRV/air vent/LWCO adapter tree, threaded connection adapter with clip and LWCO plug.

With our cascading technologies, the number of units operating is determined by the system demand to help meet the hydronic space heating requirements. As demand increases additional units will be enabled to meet higher heating requirements. Conversely, as system demands decreases, the number of operating units will decrease until the heating requirement is met.
The Navien cascading system also balances out the workload of each unit for longer life. The NHB-H is also certified for common venting, reducing the venting and number of terminations required.
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 and 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.
* Existing installations may require the purchase of a new main PCB and front control panel.
