Ideal isar he30 expansion vessel pressure

[spannermonkey72]

How do you check the pressure of the expansion vessel on an Ideal isar HE30 (not water pressure) & what is the ideal operating pressure?

 

[vicvapour]

Attach a pressure meter to it, bosch do one

From the manual;

An 8-litre expansion vessel, with an initial charge pressure
of 0.75 bar.

Do you know where the valve is to check it is?

 

[vicvapour]

Yes, it on top of the expansion vessel, if your not too confident doing it why not get a RGI to check it for you my friend.

Thanks, I'd searched the net for a picture to show where the valve is located but couldn't find one. Thanks for your advice

The valve on the exp vessell is on the front of the vessell near the fan so removal of the combusion cover is required to access

Pressed the Thanks button!

Maybe back to ask more advice

Anytime bud

The system water pressure will need to be released when checking the expansion vessel pressure.
Connect a foot pump with a pressure gauge on to the schroeder valve to check the pressure.
Come to think of it,that could be the Ideal boiler with the schroeder valve behind the fan unit in the combustion chamber.Maybe best to get a GasSafe engineer in to check it.

From memory, they arent too bad on these access from the top is normally okay on the HE's.

No. !! Vic hasn't a clue !! Everyone else's info is correct.
Best to remove fan ,
Yes I do know how old this thread is , but it's a valuble resource , and this thread gave me the correct answer , despite the best patronising guess work of Vic !!!
