*Based on NFC-250/200H.
**Whole house refers to combi-boilers that offer at least 150,000 BTU/H for DHW.
COMPARE
these advantages and see why NFC-H combis are the right fit for small and large homes
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.
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.
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
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.
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.
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.
Built-in DHW module now with
advanced performance
Navien’s new innovative domestic hot water heat exchanger now generates even more hot water, giving customers the ability to run up to 3 showers and a dishwasher, all at the same time with 5.4 gallons per minute at a 67°F temperature rise.
Advanced
user interface control with setup wizard
Navien’s new backlit control panel is simple and intuitive to use with its plain text display and an innovative click wheel that improves usability for all information input
Built-in hardware to connect up to
3 zone pumps or 3 zone valves
With Navien’s new PCB design you now have the ability to connect 3 zone pumps.
Optional magnetic boiler filter
The NaviClean™ is designed to work with Navien NFC-H Series boilers. It is best suited for heating systems with 1" to 1-1/4" copper or black iron pipes. It features a permanent magnet mounted inside the glass reinforced nylon housing.
The NFC-H can be cascaded with up to 15 Navien NPE tankless water heaters
Common vent up to 8 units
One NFC-H combi-boiler can be common vented with up to 7 NPE tankless water heaters. The NFC/NPE systems are approved for single pipe (exhaust) and dual pipe (fresh air intake and exhaust) installations.
