Navien NCB combi-boiler

Always innovating, Navien is introducing their next generation combi-boiler, the NCB-E. Navien’s NCB series is unique in that, as one unit, it is capable of providing a whole house heating system while also providing the domestic hot water output of a stand-alone tankless water heater. The NCB-E 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. www.wholehousecombi.com.
