Description
12L Pressure Vessel for 100L and 120L Water Heaters
A 12L pressure vessel helps manage pressure changes in a water-heating installation supplied by a pump. Water expands as it heats, which can increase pressure in a pumped or closed system. A correctly selected and installed vessel provides space for this expansion and helps reduce unnecessary pressure stress within the system.
Suitable Water Heater Sizes
This model is intended for water heaters with a maximum capacity of 120 litres. It is compatible with Atlantic 100L and 120L water heaters, making it suitable for larger domestic hot-water installations.
Vessel sizing also depends on the system pressure and installation conditions. Therefore, the 12L capacity and pressure setting should be confirmed by a qualified plumber or technician before installation.

Why Use a Pressure Vessel?
A pressure vessel accommodates changes in water volume and pressure during the heating cycle. This can help the system operate more reliably when the installation includes a pump or behaves as a closed system.
The vessel should be correctly sized, charged and installed. It does not replace the safety valve or any other safety component required by the water-heating system.
Pressure Vessel or Expansion Vessel?
This type of component may also be described as an expansion vessel. Both terms are commonly used for a vessel that provides space for water expansion and helps manage pressure changes in a water-heating installation.
Installation Guidance
The vessel should remain accessible for inspection and maintenance. Before use, the installer should confirm the system pressure, preset charge, connection and suitability for the water heater. The completed installation should then be checked for leaks and correct operation.
