Expansion Vessel Capacity
Glow-worm 0020097328 is commonly catalogued by major UK heating merchants as a 10 litre expansion vessel.
Some current boiler-spares databases alternatively describe the same manufacturer part number as an 8 litre vessel. For this reason, if capacity is critical for your application, confirm the specification shown on the label of the supplied vessel or against the appliance manufacturer's technical information.
What Does an Expansion Vessel Do?
Water expands as it is heated. In a sealed central-heating system there needs to be somewhere for this additional volume to go without causing the system pressure to rise excessively.
The expansion vessel contains a flexible internal diaphragm separating the heating water from a pressurised air or gas chamber.
As the heating water expands, it pushes against the diaphragm and compresses the air side of the vessel. This helps keep system pressure within the intended operating range.
Possible Symptoms of Expansion Vessel Failure
A failed, discharged or damaged expansion vessel may contribute to symptoms including:
Boiler pressure rising significantly when the heating is switched on
Pressure dropping again when the system cools
Frequent requirement to repressurise the heating system
Pressure relief valve discharging water
System pressure approaching or exceeding 3 bar
Water escaping through the pressure relief discharge pipe
Boiler pressure fluctuations between hot and cold operation
These symptoms may also be caused by other heating-system faults. The appliance should therefore be professionally diagnosed before replacing the expansion vessel.

Important Compatibility Information
Always confirm compatibility before ordering.
Glow-worm has produced many boiler variants and revisions. Components can vary depending on the exact appliance model, production date, Gas Council number and serial number.
The safest method is to confirm that manufacturer part number 0020097328 is specified for the appliance.
If you are unsure, provide the full boiler model, Gas Council number and serial number before ordering.
Professional Installation Recommended
Replacement of an internal boiler expansion vessel normally requires the heating circuit to be isolated and depressurised.
The replacement vessel must also be correctly installed and the heating system repressurised and tested afterwards.
Where access requires removal of the boiler's room-sealed combustion casing or other work covered by gas-safety legislation, the work must be carried out by a suitably qualified Gas Safe registered engineer.
