When it may not be suitable
This expansion vessel is not suitable for open-vented heating systems or domestic hot water potable water supplies, as it is specifically engineered for closed central heating circuits.

How to use
Installation should be performed by a qualified heating technician in accordance with local regulations and manufacturer guidelines. The vessel must be securely mounted to a suitable wall using appropriate hanging hardware and connected to the return or supply line of the closed central heating system. Ensure that an isolation valve and draining point are included in the setup for future maintenance. Once installed, verify that the system is properly filled and that the pre-charge pressure aligns with the specific requirements of the heating installation before putting it into operation.
What to consider before purchase
Verify that the 8-liter capacity meets the specific expansion requirements of your heating system
Ensure the maximum pressure rating of 3 bar is compatible with your installation
Check that your system is a closed central heating circuit
Confirm that adequate wall space is available for hanging installation
Usage recommendations: Regularly inspect the expansion vessel annually as part of routine central heating maintenance to check for signs of wear, correct pressure levels, and secure mounting. Prompt professional checks are advised if unexpected pressure fluctuations occur within the heating system.
