size of cwsc

[dib79]

hi all ,is a 25 gallon cwsc big enough to supply hot cylinder 36/18 and cold feed to shower,hot cylinder is just for shower too so no other outlets,would need small pump for shower as not enough head without one

It all depends on the flow rate of the shower/outlets compared with the incoming supply flow rate.

Many would use a 50 gall cistern as that would supply many showers without needing any fill during the shower.

thanks for reply,im limited for space as there is no loft to put tank in,the main bathroom has cylinder under cwsc in a big cupboard,high ceilings so room to sit cwsc high enough on specially made frame,the bathroom is long way from bedroom where ensuite is to go so i want to recreate this system just for one shower,would have to fit pump as although ceilings are high cwsc wont be high enough for gravity alone,i think 1.5bar pump is smallest i could fit ,the incoming pressure is 2 bar,is there a chance i could get away with 25 gallon tank,wouldve gone for electric shower but there are others in the house and electrician says supply is not good enough
