What it is
The Vokera 10028811 is an expansion vessel used in the Vokera Unica 32 BHE gas boiler. It absorbs the volume increase of water as the system heats, holding the sealed system pressure within its design range. The vessel is a serviceable component within the boiler casing.
Signs this part needs replacing
- System pressure rises sharply as the boiler heats and falls again once it cools.
- The pressure relief valve discharges water, or the discharge pipe is wet.
- The boiler repeatedly loses pressure and needs topping up.
- Water is present at the vessel's air charge valve, or the charge cannot be held.
- Pressure gauge readings swing widely during normal operation.
Before you order
- Confirm the boiler model is the Vokera Unica 32 BHE.
- Check the part number on the existing vessel against 10028811.
- Verify the vessel's connection type and charge pressure against the manufacturer's parts list for this model.
- Check the system pressure and expansion vessel charge before condemning the part.
