Innovations make Navien condensing combi-boilers the best choice for homeowners
Stainless steel heat exchanger
Navien’s advanced stainless steel heat exchanger design resists corrosion better than copper for longer life.
High flow rates
Separate stainless steel flat plate heat exchanger for DHW creates one of the highest flow rate for any combi‑boiler in the industry. (NCB-H up to 5.4 GPM @ 70º temperature rise; NFC-H up to 5.4 GPM @ 67º temperature rise)
Optional NaviLink™ Wi-Fi
control systemThe NaviLink™ Wi-Fi control system provides access to NCB-H and NFC-H condensing combi-boilers from anywhere in the world
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 60', or up to 150' with 3" venting.
Low noise levels
Installations in or near media rooms, recreation rooms or any living areas of the house are possible with the quiet running Navien combi-boilers.
High turndown ratios up to 11:1
The sophisticated gas flow control system provides a high turndown ratio, reducing energy waste and excessive combi-boiler cycling and enhances temperature control for DHW. (NFC-H 11:1 for heating and DHW; NCB-H 6:1 heating, 11:1 DHW)
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.
The ultimate
in energy efficiency
Navien condensing combi-boilers are Energy Star certified, providing an AFUE of 95.0%. These extremely efficient and eco-friendly units provide extra energy savings over a traditional floor standing boilers and storage tanks.
