BENEFITS OF A 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)

Tankless boiler don’t require much maintenance, cleaning them once a year is going to expand the lifespan and reduce the risk for corrosion.

The goal of routine tankless maintenance is to prevent scale from building up inside the heat exchanger, keep filters, igniters, fans and burners clean, and check gas pressure, proper venting and system performance. Over time, we’ve found that the average household benefits the most from annual service plans. With proper maintenance your tankless water heater will be more efficient, more reliable, and have a significantly longer service life.
