BENEFITS OF A NAVIEN COMBI-BOILER
Hot Water Innovation
Homeowners Can Trust
Durable Heat Exchangers
Navien combi-boiler heat exchangers are built with durable stainless steel.
Low run cost
A separate stainless steel flat plate heat exchanger for DHW creates one of the highest flow rates 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)
Remote temperature control
The 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 the use of PVC, CPVC, polypropylene (rigid and flexible), and stainless steel venting reducing installation time and costs. The 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.
Precise temperature control adjustment
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)
Explore Navien Combi-boiler Applications
Navien Combi boilers offer endless hot water on demand for any size home, and with heat inputs up to 199,000 BTU/H, they are compatible with a variety of whole house heating applications such as finned tube and cast iron baseboards, radiant floor heating systems, fan coils, radiators, and air handlers.

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.
