What it is
The Vokera 10020839 is a 6 litre expansion vessel used in Vokera Mynute boilers. It absorbs the expansion of water as the heating system heats up, limiting the pressure rise within the sealed circuit. It is fitted to the Mynute 12E, 16E and 20E models.
Signs this part needs replacing
- System pressure rises sharply when the boiler heats up
- Pressure relief valve discharges water during heating cycles
- Boiler pressure drops repeatedly and needs frequent topping up
- Pressure gauge swings widely between hot and cold states
- Water present at the pressure relief discharge pipe
Before you order
- Confirm your boiler model and GC number against the fitment list
- Check the existing vessel's capacity and connection details
- Verify system pressure and inspect the pressure relief valve
- Isolate and depressurise the boiler before fitting
