Navien is proud to announce that the new NFC-H condensing fire tube combi-boiler has won the 2021 Vision Award for HVAC from FacilitiesNet. The 3rd Annual Vision Awards honor innovation and excellence in products that contribute to the efficient and profitable operations and management of institutional and commercial buildings in the United States. The NFC-H is the third Navien product to win a FacilitiesNet Vision Award after the NFB fire tube boiler won for HVAC in 2019 and the NFB-C commercial fire tube boiler also won for HVAC in 2020.
Navien NFC-H Combi-boilers patented fire tube technology makes them a smart choice for moderately sized space heating applications that require domestic hot water. At 95.0 percent AFUE, this ENERGY STAR product can result in lowered operating cost for building owners.
Powerful heating performance with inputs of 175,000 Btuh (NFC-250/175H) and 199,900 Btuh (NFC-250/200H) coupled with a 210,000 Btuh domestic hot water input with a flow rate of 5.6 gpm at 67ºF rise allows the NFC-H combi-boiler to be used in applications that would typically consist of a boiler connected to a separate tank-style water heater. Up to 15 NPE-2 tankless water heaters can be cascaded to the combi-boiler for applications that require larger domestic hot water flow rates. The NFC-H features an up to 15:1 turndown ratio, which minimizes boiler cycling and improves savings.
The compact design of the NFC-H offers space savings, and common venting capability for up to eight units allows for lower installation cost and fewer wall penetrations. Single units can be vented with 2-inch PVC up to 65 feet or 3-inch PVC up to 150 feet for additional savings.
Advanced controls and a built-in Setup Wizard with intuitive display on the NFC-H can save installers time by providing diagnostics and troubleshooting. Onboard connections for a boiler pump, three zone pumps, or three zone valves are included. Optional NaviLink™ remote access allows control of the boilers, troubleshooting, operating status, notifications, and historical performance data.
The NFC-H combi-boiler is certified for installations up to 10,100 feet (NG/LP) while offering the highest domestic hot water capability for both residential and commercial applications.
