What it is
The Vaillant 0020222906 is a heat exchanger used in Vaillant VWF and Flexotherm hot water cylinders. It transfers heat from the primary circuit into the domestic hot water store, and is supplied as a service component for the appliance families listed below.
Signs this part needs replacing
- Water weeping or visible staining around the heat exchanger body or its connections
- Loss of primary circuit pressure that cannot be traced to any other component
- Reduced hot water output or slower recovery of the cylinder store
- Scale or sludge build-up restricting flow through the exchanger
- Overheating or temperature faults logged against the cylinder
Before you order
- Confirm the appliance model and variant from the data plate, as VWF 57/4 and VWF 87/4 use different cylinder sizes
- Check whether the installation is a Flexotherm variant before ordering
- Verify the existing part number against the manufacturer's parts list for your appliance
- Work on the primary circuit and cylinder should be carried out by a competent heating engineer
