Lack of shower pressure

Hi all,

I have a problem with my shower at home and need advice from you guys.
I have an indirect system installed and have 2 showers ( not power showers) just standard thermostatic control type, heating circuit is perfect and boiler pressure perfect at 1.5 bar, the top floor shower works perfect with a powerful flow out of the showerhead but the lower floor shower has a almost non-exsistant flow of water after about 20 secs after turning it on, now the hot water cylinder is on the same floor as the shower not working but the top floor shower works perfect which seems strange as id thought it would be the other way around BUT when you lower the non working showerhead to the floor it starts to flow again, seems to be a gravity problem...?

Please help!!!

Thanks in advance
