Combi-boiler acts as home heating, hot water system

Navien released its next generation NCB-E combi-boiler, which provides users with a home heating system and a domestic hot water output of a standalone tankless water heater. The NCB-E is a rolling replacement with a Grundfos pump, an integral air vent and a PRV top connection. The combi-boiler also features a quiet fan and front cover bevel design.
