What it is
The Ravenheat 6 litre expansion vessel (part 0004VAS09010/0) is a sealed-system component used across a range of Ravenheat gas boilers. It absorbs the expansion of heated water in the central heating circuit, helping to maintain stable system pressure and protect components from excess stress.
Signs this part needs replacing
- System pressure rises quickly when the boiler is running and falls when it cools.
- Boiler requires frequent topping up to maintain pressure.
- Water is discharged from the pressure relief valve during heating.
- Boiler locks out or shows a low-pressure fault.
- Banging or knocking noises from the boiler or pipework.
Before you order
- Check your boiler model and GC number against the fitment list above.
- Confirm the existing vessel's capacity and connection type match this 6 litre part.
- Ensure the system is fully depressurised before removal.
- Verify the vessel's pre-charge pressure is suitable for your system.
