Navien NFC-250/200H Condensing Combi-Boiler
Engineered for homes and light commercial spaces that demand both powerful heating and abundant hot water, the Navien NFC-250/200H is a premium condensing combi-boiler that delivers 199,900 BTU for domestic hot water and 210,000 BTU for space heating — all from a single, compact, wall-mounted unit.
Rated at 95% AFUE and Energy Star certified, this high-efficiency system helps homeowners and contractors reduce energy consumption without compromising on comfort or performance. Its 15:1 turndown ratio — one of the widest in its class — allows the boiler to precisely match output to actual demand, minimizing short-cycling, improving comfort, and maximizing long-term energy savings on both heating and hot water production.
The NFC-250/200H features a redesigned domestic hot water module with integrated mixing and water adjustment valves, delivering stable, consistent hot water temperatures even under fluctuating demand. Installation and daily operation are simplified through Navien’s advanced control system, featuring an intuitive interface and a guided Setup Wizard, while built-in powered connections support up to three zone valves or pumps for flexible, multi-zone hydronic heating configurations.
Built to last, the unit is constructed around a patented stainless steel fire tube heat exchanger and a non-metallic condensate base, offering superior corrosion resistance and long-term reliability. Flexible venting options — 2″ pipe runs up to 65 feet or 3″ runs up to 150 feet — make installation adaptable to a wide range of building layouts.
Designed for scalability, the NFC-250/200H is approved for high-altitude installations up to 10,100 feet on both natural gas and propane, with conversion kits included. For larger-capacity projects, it can be common vented with up to seven NPE units or cascaded with up to fifteen units, providing a seamless path to expand heating capacity as demand grows.
Whether for residential space heating, multi-fixture domestic hot water supply, multi-zone hydronic systems, or large-scale cascade installations, the Navien NFC-250/200H combines efficiency, durability, and intelligent control in one dependable solution.
