Navien Condensing Heating Boiler (NHB)

The NHB series of Navien condensing heating boilers is a wall-mounted, tankless water heating unit that comes in various models, depending on your hot water needs. The unit provides a continuous flow of hot water, thus offering savings on energy and fuel. Because Navien heating boilers use condensing technology, they retain and recycle some of the heat and exhaust gasses that would be lost in more conventional units, which further improves their energy efficiency. They have an impressive 95% AFUE efficiency rating.

Each model in this series is lightweight, compact, and easy to install. They also feature a control system that can be accessed remotely with NaviLink™, which means that you can make temperature adjustments via Wi-Fi from anywhere.

The NHB models are compatible with multizone systems and are available in four different capacities:

NHB-55 (55K BTU)
NHB-80 (80K BTU)
NHB-110 (110K BTU)
NHB-150 (150K BTU)
