What it is
The Vaillant 0020018069 is a water quantity limitator rated at 10.4 litres per minute. It regulates the domestic hot water flow rate through the boiler, keeping the draw-off within the design figure the appliance was set up for. It is used across the Vaillant ecoTEC Plus and ecoTEC Pro combi boiler families.
Signs this part needs replacing
- Domestic hot water flow rate noticeably lower than the rated 10.4 L/min at the outlet
- Flow rate that varies or drops away as the tap runs
- Reduced hot water performance at outlets that was previously acceptable
- Debris or scale build-up found in the limiter when the water section is opened
- Limiter housing damaged, distorted or failing to seat correctly on reassembly
Before you order
- Confirm the boiler model and revision from the data badge, as several VUW variants use this limiter
- Check the existing limiter's rated flow figure matches 10.4 L/min
- Verify the part number 0020018069 against the manufacturer's parts list for your appliance
- Inspect the water section for scale or debris before fitting, as the cause of low flow may lie elsewhere
