What it is

The pipe heat exchanger inlet is a Navien component for the NCB300-28K Combi boiler. It forms the inlet connection to the heat exchanger, carrying water into the exchanger body as part of the appliance's heating circuit. It is supplied as an individual pipe component identified by part number 30029033A.

Signs this part needs replacing

  • Visible corrosion, pitting or scaling on the pipe surface
  • Weeping or dripping from the inlet joint or pipe body
  • Water staining or mineral deposits around the heat exchanger inlet connection
  • Loss of system pressure traced to the inlet pipework
  • Leaks that persist after the joint has been correctly remade

Before you order

  • Confirm the appliance model is the NCB300-28K Combi
  • Check the existing part number against 30029033A
  • Inspect the inlet connection and surrounding pipework for additional damage
  • Verify that any leak is from the inlet pipe and not an adjacent joint or seal
