Expansion Vessel Sizing Guide

11/03/20

Sealed Heating Systems need to be designed so that we control the maximum temperature that the system reaches and have adequate management in place, should this maximum be exceeded.

Within these systems, the thermal expansion of water must be compensated for and this is normally achieved with an expansion vessel.

Vessels are sized according to the volume of the system, the maximum temperature that the system generates, and also the head above the vessel.

Arrow Valves manufacture a range of pressurisation units and expansion vessels – we can provide these as a complete package with all required ancillaries and the correct vessel sizing.

We can also provide assistance with vessel sizing for specifiers – click here to view our expansion vessel guide or contact us with your system parameters.
