moving hot water cylindr

[wildcard]

Got a cust who has a 36x18 vented cylinder fitted in the corner of a kitchen on a flat he is doing up.He wants it moved into a cupboard which has no access to hots or cold unless I go up into the loft.
The excisting cylinders hot water & vent all disappear into a stud wall behind the bathroom.
Any ideas how i can move this without it airlocking,maybe a surrey flange.
P.S its a direct cylinder

any chance you can replace with an unvented cylinder or too much hassle ?

how high is the tank in the loft? not resting on joists i hope

All new pipework feed, open vent from tank in loft just make sure your loft pipework has a smooth run and not going up and down like some people have.. Shouldnt have to worry about surrey flange etc

Do it as it should be done with new vent to loft. Unorthodox solutions, to help a client, can bite you in the Rse.
