    The NaviLink™ Wi-Fi control system provides access to NFC-H condensing combi-boiler from anywhere in the world

  • Nfc-feature-venting

    Multiple venting options

    Low exhaust gas temperatures allow use of PVC, CPVC, polypropylene (rigid and flexible) and stainless steel venting reducing installation time and costs. System can use 2" venting for up to 65', or up to 150' with 3" venting.

  • Nfc-feature-closet-lvg-room

    Low noise levels

    Installations in or near meeting rooms, offices or any areas

Lower energy bills, easier on the planet

 
Navien condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing boilers. The result is a reduction in energy consumption, lower CO2 emissions and low exhaust temperatures allowing the use of less expensive venting materials such as Schedule 40 PVC.
