The Navien NCB-190/060H Combi Boiler is a premium high-efficiency condensing unit that delivers both home heating and on-demand domestic hot water in a single, space-saving system. With an output of 60,000 BTU/h for heating and up to 190,000 BTU/h for hot water, it’s the ideal choice for modern homes, townhouses, and condos looking for reliable comfort and reduced energy bills.
Powered by advanced condensing technology, the NCB-190/060H captures and reuses exhaust heat to achieve up to 95 % efficiency, lowering gas consumption and operating costs. Its stainless-steel heat exchanger ensures exceptional durability and corrosion resistance, while the smart modulating burner automatically adjusts output based on demand for consistent performance.
