Navien Tankless Water Heaters 30004827B Cold Water Inlet Adapter

The Navien Tankless Water Heaters 30004827B is a copper inlet adapter for Navien combi boilers only and is made from copper. The position of the appliance is rather simple; it links the cold water supply line to the boiler. The design of the adapter makes it easy to screw it on the inlet port of the boiler and on the other end to the cold water line thus ensuring that it is leak proof. This means that the water which is required in the boiler will always be flowing in as cold water to maintain the process. In all Navien combi boilers, cold water is used in both the heat exchanger and for making domestic hot water.
