What it is
The Vaillant 0020166565 is a domestic hot water (DHW) heat exchanger used in Vaillant VPM pump units. It transfers heat from the primary circuit into the domestic hot water supply. It is a serviceable component within the DHW side of the appliance.
Signs this part needs replacing
- Reduced or inconsistent domestic hot water temperature
- Scale or debris build-up restricting flow through the DHW circuit
- Water weeping from the heat exchanger body or its connections
- Kettling or banging noises from the DHW side during draw-off
- Repeated overheat or DHW-related fault codes on the appliance
Before you order
- Confirm the appliance model matches one of the VPM units listed above
- Check the part number on the existing heat exchanger against 0020166565
- Verify the fault is on the DHW circuit and not the primary side or controls
- Confirm access and isolation arrangements before removing the existing component
