As the leader in condensing technology, Navien has already reinvented the water heating industry with the award-winning NPE tankless water heaters and the NCB-H combi-boilers. Our new NHB-H boiler series is the next in a long line of innovations from Navien. All boilers have Navien’s advanced burner system, an industry-leading AFUE of 95% and turndown ratios up to 15:1.

Now available in four sizes: NHB-55H, NHB-80H, NHB-110H and NHB-150H.

The industry’s largest turndown ratio in the NHB-150H minimizes short cycling and provides better reaction to changing heating demands throughout the year.
