I know a comi can give between 9 - 14
litres per minute of hot water.

It can give up to 22 litres/min, depending on which one you buy.

Does anybody know the flow rate of hot water
from a standard 110 litre indirect copper cylinder.

DEpenmding on the height of the tank above and the size of the cold feed
pipe. Apprix 25-30 litres/min on avaerge, but at a very low pressure.
Volume but no pressure.

If the cold water header tank is
approx 2m above the cylider then is
there 0.2bar pressure......
What would be the flow rate????

You will have to run around the shower to get wet. You can use a venturi
shower that takes it cold off the high pressure mains and hot from the
low
pressure cylinder. Works well.

But not as well as installing a good quality shower pump like a Stuart
Turner and getting good flow and pressure. At least 25lpm at two
showers concurrently.

This is tripe information. Expensive, noisy, vibrates, wakes the house up,
uses too much water making you water bill large, empties the cylinder far
too quickly, souses more gas to heat all the wasted water, etc. Totally
silly idea. Intelligent people don't use them.
