High Efficiency Condensing Combi-Boiler, AFUE 95%, Space Heating Up to 199,900 BTU/h, Domestic Hot Water Up to 210,000 BTU/h
Dual stainless steel heat exchanger: Durable stainless steel heat exchangers resist corrosion, resulting in longer life and improved heat recovery from flue gases for superior efficiency.
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 NCB-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.
