What it is
The Ferroli 39841230 is an 8 litre expansion vessel used in Ferroli domestic gas boilers. It absorbs the volumetric change of the system water as it heats and expands, limiting pressure rise within the sealed heating circuit. It is a service component for the appliance families listed below.
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 during normal heating cycles.
- The boiler loses pressure repeatedly and needs frequent topping up.
- Water is present at the vessel's connection or the vessel feels heavy when disconnected.
- The boiler locks out on a low or fluctuating pressure fault despite the system being correctly filled.
Before you order
- Confirm your boiler model and product number against the fit list above.
- Check the capacity marked on the existing vessel to confirm 8 litre is correct for your appliance.
- Inspect the vessel connection, mounting and pipework access before removal, as space around the vessel varies by model.
- Verify the part number 39841230 on the existing component or the manufacturer's parts list for your appliance.
