NFC fire tube combi-boilers – Navien
Navien introduced its new NFC series stainless steel fire tube combi-boilers available in two sizes: NFC-175 (175,000 Btuh) and NFC-200 (199,900 Btuh). The company says the combi-boilers provide enough heating input for up to a 3,500-square-foot home and continuous domestic hot water supply for up to three bathrooms. Ideal applications include retrofits and new installations in single-family homes, multifamily houses, and light commercial buildings.
The new Navien NFC combi-boiler models come with a patented in-house designed and manufactured heat exchanger, low profile burner for ease of service, advanced controls offering intuitive user navigation, a built-in DHW module (pump, flat plate heat exchanger, 3-way valve, mixing valve, water adjustment valve, and auto water fill valve), common venting capability up to eight units, cascading capability up to 16 units, and built-in hardware to connect up to three zone pumps without a need for additional external controllers.
