What it is

The Heatline Heat Exchanger By-Pass Pipe is a pipe component used within the heat exchanger circuit of Heatline gas boilers. It carries the by-pass flow around the heat exchanger, helping to maintain correct circulation and temperature control through the appliance. This part is listed under Heatline's heat exchanger category for the S30 System and Compact S30S System models.

Signs this part needs replacing

  • Visible water weeping, staining or crusting around the by-pass pipe or its joints
  • Corrosion, pitting or thinning on the pipe surface
  • Kettling, noisy circulation or uneven heat output from the boiler
  • Repeated overheating or overheat lockout linked to poor circulation through the heat exchanger
  • Scale or debris build-up restricting flow through the pipe

Before you order

  • Confirm your boiler model against the fit list above before ordering
  • Check the part number on the existing pipe matches D003200445 or the replaced code 3003200445
  • Verify the GC number on the appliance data badge where available
  • Inspect the surrounding heat exchanger connections for damage that may also need attention
