This 18-litre heating expansion vessel is designed for use in sealed central heating systems, providing a dedicated space for water to expand as it heats. It is typically installed by heating engineers as part of new installations or when upgrading existing systems where no feed or expansion tanks are used.
Its main function is to help maintain system pressure, supporting stable boiler operation and helping to prevent pressure-related issues during heating cycles. The vessel is suitable for domestic and light commercial heating applications, offering straightforward connection to a range of compatible heating setups.
