What it is
The Intergas 864107 is a flat-type expansion vessel used in Intergas Combi Compact ECO RF and Compact HRE boiler ranges. It absorbs the volume increase of water as the system heats up, holding the sealed system pressure within its working range. The vessel is charged with air on one side of an internal diaphragm, which separates it from the heating water.
Signs this part needs replacing
- System pressure drops repeatedly and needs frequent topping up
- Boiler pressure rises sharply once the system is hot
- Water discharges from the vessel's air charge valve when the cap is depressed
- The vessel feels heavy or waterlogged when the system is drained
- Visible corrosion or weeping at the vessel connection
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the existing vessel is the flat type used on these ranges
- Verify the part number 864107 on the vessel or the manufacturer's parts list
- Check the system charge pressure and expansion vessel pre-charge before condemning the part
