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.

  • 10-1-ratio-nfb-2

    TDR 15:1 for DHW and up to 11:1 for heating

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