NHB-80 HIGH EFFICIENCY CONDENSING HEATING BOILER

Navien innovation in a compact wall-hung condensing boiler

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.

NHB Integrated control

The integrated control provides industry leading options and features in the boiler operation parameters, including:

  • Adjustable heat capacity.
  • A timed hydronic supply water boost feature.
  • Adjustable anti-cycle timer.
  • Freeze protection.
  • Pressure LWCO with manual reset.
  • Adjustable minimum burner time setting.
  • Adjustable turn down ratio timing.
  • Outdoor reset and domestic hot water priority.
  • Adjustable outdoor temperature reset curves.
  • Field gas convertible.

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 tankless water heater, combi‐boiler and boiler.

* Existing installations may require the purchase of a new main PCB and front control panel. Units produced on or after 2-22-16 will be compatible out of the box.
