Expansion vessel above main tank?

[connick159]

Hi all,

Any reason the white expansion vessel in the pic could not be moved to above the main tank?

I asked for it to go above the tank given we have the room and I was planning to build a partition around the tank and this now is a bit of a rethink with where they have put the expansion vessel.

I questioned the location when I came back to site but the installer simply told me it has to be no higher than the tank. 

Any experience of this on here I'd love to hear comments.

Thanks

Both my expansion tanks are above their larger tanks (buffer and DHW).
