expantion vessels

[jedi 436]

what size expantion vessel do i need , does it depend on ur system capacity

 

[tweakyboy]

What is it for, heating or hot water?

 

[jedi 436]

its for the central heating

 

[jedi 436]

its for the cental heating it keeps building pressure up above 3 bar then venting of i had an external vessel fitted a few years ago but it looks as though its faulty and ive no idear of its capacity

Might just need re pressurising.

 

[jedi 436]

thanks ill try that is it still 1/1.2 bar

 

[SimonG]

1 bar for me, but don't forget to drop the system pressure first. If you get water out the schrader valve I would say its goosed. If there's no label on it to give the capacity just measure it and take the measurements into the plumbers merchants, they should be able to help.
