COMPARE these advantages and see why NFC-H combis are the right fit for small and large homes

 

  • Nfc-h-feature-dualinputs

    Dual inputs of 210,000 BTU/H for DHW and up to 199,900 BTU/H for heating

    Satisfies all the space heating and domestic hot water requirements of most typical large homes.

  • Nfc-h-feature-size-comp

    Space saving and light
    weight design

    Navien’s sleek wall-hung combi-boilers occupy 80% less space than traditional floor standing boilers and tank water heaters.

  • Nfc-h-feature-dual-venturi

    Dual Venturi and field gas convertibility

    Dual Venturi system creates better combustion control and turndown ratio. Field gas convertibility is easy with orifice conversion kits for NG high altitude (5,400–10,100 ft.) and LP (up to 10,100 ft.) included with NFC-H Series combi-boilers

  • Nfc-h-feature-dhw-mod-easy-access

    Easy access to DHW module
    and valves

    All components of DHW module including water feed valve, flow adjustment valve, mixing valve and 3-way valve are right behind circuit board for easy serviceability.

  • Nfc-feature-closet-lvg-room

    Low noise levels

    Installations in or near media rooms, recreation rooms or any living areas of the house are possible with the quiet running NFC-H combi-boilers.

  • 10-1-ratio-nfb-2

    TDR 15:1 for heating and for DHW

    The sophisticated gas flow control system provides a high turndown ratio, reducing energy waste and excessive boiler cycling and enhances temperature control for DHW.

Patented stainless steel fire tube heat exchanger


Navien’s advanced patented stainless steel heat exchanger design is ASME‑Certified,
“H” Stamped, and reduces high stress point weld failures common on other combi-boilers.
This compact, in‑house designed and manufactured heat exchanger uses the latest automated laser welding technology to deliver superior product quality.
