Negative if above, positive (or negative) if below (or marginal).
Connecting to those cyinders can be problematic. Ideally make a holeinthe side and fit an Essex flange. Then it needs a fast flow into the top tank if the volume's small.
Assuming the shower is a mixer of some sort, and the cold is off the rising mains use a negative head pump.
As per twgas, storage is a big issue (or in a combination cylinder a little issue) as there is not realy enough there to pump in the first place.
Hope this is of help.

Good afternoon,
Combination Fortic type cylinders shouldn't be pumped from because they usually only have around 7gal usable cold water and cant have a starvation kit attached.
Usually, we would warranty a pump on a combination cylinder.
