What it is
The Vaillant 0020020015 is a plastic three-way diverter valve used in Vaillant ecoTEC Plus and ecoTEC Pro boilers. It directs water flow between the central heating circuit and the domestic hot water circuit according to demand. The valve body is manufactured in plastic.
Signs this part needs replacing
- Domestic hot water runs cold or only lukewarm while the heating circuit is calling.
- Radiators warm up when hot water is drawn, indicating the valve is not diverting fully.
- Hot water temperature fluctuates or drops out during a draw-off.
- The valve head does not move when the boiler switches between heating and hot water.
- Water weeping or staining around the valve body or its connections.
Before you order
- Confirm the boiler model and GC number against the fitment list above.
- Check the part number on the existing valve matches 0020020015.
- Verify whether the boiler uses the plastic-bodied valve before ordering.
- Inspect the valve head and body for damage so the correct assembly is replaced.
