What it is
The Vaillant 0020174498 is an 11kW evaporator used in Vaillant Arotherm air source heat pump outdoor units. It absorbs heat from the outdoor air into the refrigerant circuit, forming the low-temperature side of the heat pump cycle. It is a manufacturer-supplied component for the VWL 115/2 A 230V appliance family.
Signs this part needs replacing
- Reduced heating output or the heat pump failing to reach expected flow temperatures
- Ice build-up on the evaporator that does not clear during a defrost cycle
- Visible frost patterns concentrated on part of the coil only, indicating a restricted or damaged circuit
- Physical damage to the fins or coil, such as impact damage or corrosion
- Refrigerant loss traced to the evaporator coil
Before you order
- Confirm the appliance model and variant match the fitment list above
- Check the existing evaporator part number against 0020174498 before removal
- Verify the fault is with the evaporator itself and not the defrost controls, fan or refrigerant charge
- Confirm the unit is isolated and refrigerant recovered before any work begins
