PSI/Bar of an expansion vessel
- Thread starter merton69
- Start date
Typically 0.8 Bar for a standard install ie. boiler not in the basement and several floors above (that would preclude a higher pressure)).
Check pressure with zero pressure on the water side of the vessel.
Be amazed if that vessel's still ok....but they were tough boilers given most were illegal installs.

In the past certain manufacturers eg. Ariston were sold through builders merchants and being cheaper than many other makes were frequently installed by non registered gas installers. Certainly in London most installs were rough. They're a nice boiler to work on with very few design faults unlike some of the higher priced boilers at the time.
