What it is

The 6319290 is the main heat exchanger body fitted to Sime's Format DGT HE boiler range. It transfers the heat produced by the burner into the water circulating through the appliance. Sime has updated this part to the current version 6319290A, which also replaces the earlier 6319201 and 9202 references.

Signs this part needs replacing

  • Water leaking from around the heat exchanger
  • Reduced or fluctuating hot water/heating output
  • Kettling or banging noises when the boiler fires
  • Lockouts linked to overheat or flow sensors

Before you order

  • Confirm the GC number on your appliance data plate
  • Match the part number printed on your existing heat exchanger
  • Isolate gas, electricity and water before removal
  • Have the replacement fitted by a Gas Safe registered engineer
