What it is
The Vokera 10028535 is an expansion vessel used in Vokera Mynute HE and Mynute I20 gas boilers. It absorbs the volume increase of water as the heating system heats up, keeping system pressure within the range the boiler expects. It is a sealed, pressurised component mounted within the appliance.
Signs this part needs replacing
- System pressure rises sharply when the boiler heats up and falls again once it cools.
- The pressure relief valve discharges water during normal heating cycles.
- The boiler locks out or shows a low pressure fault that will not hold after topping up.
- Water or corrosion is present at the vessel's air charge valve.
- The vessel feels heavy or full of water when the system is depressurised.
Before you order
- Confirm the boiler model against the fit list above, including any LPG or ERP variant.
- Check the part number on the existing vessel matches 10028535.
- Verify the system pressure and expansion vessel charge before condemning the part.
- Work on a sealed system vessel should be carried out by a competent heating engineer.
