What it is

The Vaillant 8000019435 is a condenser used in Arotherm PLUS /6 air source heat pump units. It forms part of the refrigerant circuit, where it transfers heat from the compressed refrigerant into the heating and hot water system. This component is specific to the VWL 35/6 and VWL 55/6 variants listed below.

Signs this part needs replacing

  • Refrigerant loss traced to the condenser, with repeated pressure faults
  • Visible damage, corrosion or contamination on the condenser coil or connections
  • Fault codes relating to refrigerant circuit pressure or heat transfer
  • Abnormal noise or vibration from the condenser area during operation

Before you order

  • Confirm the model and variant on the appliance data plate matches the fit list above
  • Check the part number 8000019435 against the manufacturer's parts list for your unit
