Navien NCB-240/130H High-Efficiency Condensing Combi-Boiler
The Navien NCB-240/130H is a high-efficiency condensing combi-boiler engineered to deliver powerful home heating and unlimited on-demand hot water in a single, compact unit. With 240,000 BTU/h dedicated to domestic hot water and 130,000 BTU/h for space heating, this model is ideal for medium to large homes that demand strong performance, consistent comfort, and high efficiency.
Featuring an impressive 95% AFUE rating, the NCB-240/130H uses advanced condensing technology to capture and reuse heat from exhaust gases, significantly reducing energy waste and lowering fuel consumption. This results in improved energy savings and reduced monthly heating and hot water costs.
Its sleek, wall-mounted design replaces both a traditional boiler and water heater, helping homeowners save valuable space in utility rooms, basements, or tight mechanical areas. Smart digital controls and a modulating burner automatically adjust heat output based on real-time demand, ensuring stable temperatures, fast hot water delivery, and minimal energy waste.
A durable stainless steel heat exchanger enhances heat transfer efficiency while offering long-term corrosion resistance. Combined with ultra-low NOx emissions, the NCB-240/130H provides eco-friendly performance without sacrificing power or reliability.
With flexible venting options, easy installation, and built-in self-diagnostic features, this combi-boiler is designed for long-lasting performance and low maintenance. The Navien NCB-240/130H is a smart, space-saving investment for homeowners seeking high-efficiency heating and endless hot water from one advanced system.
