Professionally installed by 4Most Energy, this model is ideal for medium-sized homes and townhouses up to 2,500 sq. ft. that need a reliable, efficient, and space-saving solution.
With 80,000 BTU/h for heating and up to 190,000 BTU/h for domestic hot water, the NCB-190/080H delivers steady performance for homes with two to three bathrooms and simultaneous hot-water demand.
Built with advanced condensing technology, it recovers heat from exhaust gases to achieve up to 95 % AFUE efficiency, helping homeowners lower energy bills while reducing emissions. The stainless-steel heat exchanger ensures long-lasting durability and resistance to corrosion, while the smart modulating burner automatically adjusts performance based on real-time demand.
This model is versatile and efficient, suitable for in-floor heating systems, hydronic baseboards, and radiators, as well as high-velocity air handler setups. However, it is not recommended for glycol-based systems or heavy-duty applications such as snow melting or garage unit heaters.
