Heating Expansion Vessels
Manage changes in water volume and pressure within compatible heating systems with our range of heating expansion vessels. Expansion vessels provide space for water to expand as it is heated, helping to accommodate changes in system pressure.
Heating expansion vessels are commonly used in sealed central heating systems and need to be correctly sized and specified for the heating system they are being installed on. Always check the vessel's capacity, operating pressure and compatibility with the system before purchasing.
Whether you're replacing an existing expansion vessel or completing a new heating installation, browse our range of heating expansion vessels for suitable solutions from Thompson and Leigh.
