The First High Efficiency Tankless Condensing Combi-Boiler that can do it all
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.
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. Your customer now has more room, saves energy and enjoys all the hot water they need, whenever they want it.
