You need to make sure that the hot supply to the shower has come off a 'surrey' flange or an 'essex' flange if it is going to a thermostatic valve. You also need to ensure that the valve supports low pressure water flow.
The pipework from the hot tank will need to be installed correctly as you may find you will have an air gap from the cylinder to the valve, causing the water to 'trickle' through the hot pipe.
You can get single impeller pumps that will pump the water, but normally that only applies to areas where overall water pressure (cold) is low.
Check the compatability of the shower valve before diagnosing any faults with the installation.
