The message
from "Roger Mills" contains these words:

Can anyone see any problems with this arrangement?

No tank-jacket? (insert smiley of choice here)

Oh yes there is! The cylinder in encased in a factory-fitted foam jacket -
that's what the green stuff is, rather than copper corrosion! g

Other than that - the only minor niggle is there's only one isolator
valve for the tank.

Why is that a problem - it's not an unvented cylinder? Are you talking about
motorised valves or manual valves? I may well put some full-bore ball valves
in strategic places in order to be able to isolate various components, if I
can fit them in.
