Storage tank

[thor2]

I need to replace a plastic 30 gallon storage tank in a cupboard but due to restrictions I can only get a 25 gallon tank to fit the space,will this affect the flow to the hot water taps? The hot water cyl is directly below the storage tank in the same cupboard,it is a downstairs flat so everything is on the one level,can anyone offer advice on this?
thanks John

Personally I think you will be fine with the flow as the head of water is the same but im sure some more qualified than I may have an opinion on this.Plenty of Scottish boys on here to give you some advice, may even be local to you.

don't see a problem with a smaller tank other than it will run out sooner if running a bath etc.

size of the tank wont effect the pressure if its at the same height, flow should be the same if piped up the same way.

I have used 28mm pipe from storage tank to cyl and came off cyl with 22mm,how soon can i reduce to 15mm to get decent pressure to taps,no bath just kitchen and bathroom sinks ?

changing the pipe to 15 will reduce preause its the hieght of the water that determines preasure

Slow the flow (outlet) down a bit or fit two ball valves so it fills quicker
