Navien NHB Condensing Boiler

Navien Condensing Boiler (NHB)



Navien NCB is the first high efficiency tankless condensing combination boiler with the capacity to supply both heat and domestic hot water for larger homes - enough hydronic heat for a whole house, plus hot water to run two showers and a dishwasher all at the same time.


The Navien NCB saves installation time and reduces call backs. In addition, the NCB takes up 80% less space than a traditional floor standing boiler and tank water heater.

Industry's largest turn down ratio providing ease of installation with multiple zones while maintaining high operating efficiencies.
