Navien’s NCB-E is its next generation combi-boiler. The series is capable of providing a whole-house heating system while also providing the domestic hot water output of a stand-alone tankless water heater. It will be a rolling replacement, now with a Grundfos pump, an integral air vent, a PRV top connection, a quieter fan and a new front cover bevel design.
