What it is

The Vaillant refrigerant buffer is a component used within the refrigerant circuit of Arotherm PLUS /6 air source heat pumps. It is supplied under Vaillant part number 0010033547 and sits in the refrigeration side of the appliance, where it helps manage refrigerant flow and stabilise the circuit during operation. It is a service part intended for repair or replacement work on the listed Arotherm PLUS /6 models.

Signs this part needs replacing

  • Refrigerant loss or repeated pressure faults traced to the buffer area of the circuit
  • Frosting or icing patterns around the buffer that do not clear during normal running
  • Abnormal noise or vibration from the refrigerant circuit under load
  • Visible damage, corrosion or mechanical deformation of the buffer
  • Fault codes or performance loss on the heating side that the manufacturer's diagnostic path attributes to this component

Before you order

  • Confirm the appliance model and variant against the fit list above, as the /6 Arotherm PLUS range uses several build revisions
  • Check the part number on the existing component or the manufacturer's parts list for your appliance
  • Work on the refrigerant circuit requires the appropriate handling and recovery equipment and a competent engineer
  • Verify whether any associated seals, pipework or fixings are also required before starting the repair
