What it is

The Andrews 7871630 is a header for the heat exchanger, supplied as a revision variant. It forms part of the heat exchanger assembly on Andrews water heaters, directing water flow through the exchanger body. It is listed within the Andrews hot water spares range.

Signs this part needs replacing

  • Water weeping or visible staining around the header joints or gasket face
  • Corrosion, pitting or scaling on the header body or its sealing surfaces
  • Repeated loss of system pressure with no other obvious source
  • Overheating or poor hot water recovery linked to restricted flow through the exchanger
  • Distortion or cracking of the header casting

Before you order

  • Confirm the appliance model and serial number against the manufacturer's parts list
  • Check the existing header for the revision marking to confirm this variant is the correct one
  • Inspect the mating gasket and fixings, as these may also need attention
  • Verify the part number 7871630 before ordering, as heat exchanger assemblies vary between models
