What it is
The Potterton 5140179 is a 7,5 litre expansion vessel supplied for Potterton Commercial boilers. It holds a sealed air cushion within the heating circuit, absorbing the increase in water volume as the system heats up and limiting the resulting rise in pressure.
Before you order
- Check the boiler model and confirm that a 7,5 litre vessel is the correct capacity for that appliance.
- Match the part number 5140179 against the existing vessel or the appliance documentation.
- Confirm that the vessel's connection and mounting arrangement suit the boiler before ordering.
- After fitting, check the system pressure and the vessel's air charge.
