What it is
The Vaillant 012993 is a water quantity limitator rated at 13 litres per minute. It is fitted within the domestic hot water circuit of compatible Vaillant gas boilers to control the flow rate through the appliance. Its function is to keep the hot water draw-off within the design flow of the boiler so the appliance can maintain a stable delivery temperature.
Signs this part needs replacing
- Reduced hot water flow rate at the taps compared with the boiler's normal delivery
- Hot water temperature fluctuating or running hot and cold during draw-off
- Boiler cycling or cutting out repeatedly while hot water is being drawn
- Scale or debris build-up visible on or around the limitator
- Poor hot water performance that persists after checking the inlet filter and mains supply
Before you order
- Confirm your boiler model and variant against the fit list above
- Check the existing limitator is rated at 13 litres per minute before ordering
- Verify the fault is not caused by scale elsewhere in the domestic hot water circuit
- Have the appliance model and GC number to hand when checking compatibility
