What it is
The expansion vessel is a 7.5 litre component from Caleffi HIU, intended for the SATK 30, SATK 40 and SATK 60 units. It provides the expansion volume that absorbs the change in water volume as a sealed heating or hot water circuit heats up and cools down, limiting pressure swings across the system. It is listed within the Caleffi HIU product range.
