sizing system for power shower

[wassanator]

IM going to be fitting a powershower in my bathroom
I know that the cold needs to be fed from the CWSC but i was wondering is a 114l tank going to be big enough as this feeds the HWC as well IM worried it might not be able to keep up with the demand

someone told me i can have a linked system could i just take the shower feed of the 2nd cistern with nothing else or would i be in danger of stagnate water

wassanator,
It's probably safer to fit a second tank linked to the original but you must take a feed out of the new tank on the opposite side to the link pipe.
