What it is

The heat exchanger inlet pipe is a Navien component (part number 30023513A) used on LCB 700 Combi Internal boilers. It carries water into the heat exchanger as part of the appliance's primary hydraulic circuit. It is a direct fitment for the LCB 700 Combi Internal range.

Signs this part needs replacing

  • Water weeping or visible staining around the pipe connections at the heat exchanger
  • Corrosion, pitting or surface degradation on the pipe body or at the unions
  • Scale or debris build-up restricting flow through the inlet
  • Cracks, deformation or a loose fit at the pipe joints
  • Pressure loss or poor heating performance traced to the inlet pipework

Before you order

  • Confirm the appliance model is an LCB 700 Combi Internal and note the output in KW
  • Check the serial number against the appliance data badge to confirm the correct build
  • Inspect the existing pipe and connections to confirm the fault lies with this part
  • Verify the part number 30023513A against the manufacturer's parts list for your boiler
