Hi all,

We have recently moved house and approx 3 years ago the previous owners had a new boiler and hot water storage cylinder fitted.

Boiler: Vaillant ecotec plus 418
Storage cylinder: Ariston Classico STI 125 HE unvented hot water storage cylinder installed in the loft

It was my understanding that an unvented water cylinder such as the above should be giving mains hot and cold pressure throughout the house. No need for shower pumps etc.
The issue we have is that the hot water pressure is shockingly bad. Eg. Running any hot tap and the pressure drops to a trickle after a couple of seconds, the shower will stop if another tap is run etc etc.

Im surprised that it is like this given the newness of the kit. Is it possible that some flow control has been installed? Or maybe there is some fault with the install or kit? Any advise much appreciated.

Thanks, Iain.

Is cold water flow ok?

The cylinder possibly needs a service, the cold feed filter could be blocked or otherwise faulty combination valve for example.
 
Thanks for the rep breesy. The cold pressure seem fine, ten times more powerful than the hot.
Not sure when, or if it's even been serviced, no details were supplied hen we purchased.
 
it should be serviced every year by someone with the G3 cert

You should get a chap with a G3 ticket to check it out and service it. Unvented cylinders should be serviced regularly, few are!
