What it is
The Heatrae Sadia flat expansion vessel has an 8-litre capacity and is supplied as part number 24100037. It is used with Heatrae Sadia HI-MAX Store cylinders to accommodate the expansion of water as it is heated. The vessel helps maintain stable system pressure and reduces the risk of pressure relief discharge during normal operation.
Signs this part needs replacing
- Pressure relief valve discharging water during heating cycles
- System pressure rising sharply or fluctuating without obvious cause
- Water weeping or corrosion visible on the vessel body
- Repeated loss of system pressure after topping up
- Vessel feels heavy or gives little or no air charge when checked
Before you order
- Confirm the existing vessel is an 8-litre flat type and matches part number 24100037
- Check the cylinder model is one of the HI-MAX Store 125L, 145L or 170L units listed
- Verify the connection arrangement and mounting position on the existing cylinder before ordering
- Ensure the system is depressurised before removal if fitting immediately
