The first high efficiency tankless condensing combi-boiler that can do it all.



Innovations make Navien condensing combi-boilers the best choice for homeowners.

The Navien NCB-E saves installation time and reduces call backs. In addition, the NCB-E takes up 80% less space than a traditional floor standing boiler and tank water heater. Navien NCB-E is the first high efficiency 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. You can now have more room, save energy and enjoy all the hot water you need, whenever you want it. Navien’s sustainable solution reduces energy consumption and lower CO2 emissions so you can help protect the environment as you add value.
