Expansion Vessel Pressure

[CarlJa]

Hi,

Should an expansion vessel pressure match the pressurisation unit?

For example, if the pressurisation unit is set at 1.2 bar should the expansion vessel be set at 1.2?

Many thanks

Better be totally clear what your referring to.
Expansion vessel on a heating system?

Yes, sorry forgot to add that bit

.2 below let’s say your cold pressure is 1.5 bar you would set the pre charge vessel to 1.3 bar
