    Hi I am looking to install an unvented water cylinder and do away with my 140lt vented set up however I only have 1.5 bar mains pressure I quite like the valliant units or 180lt indirect cylinder however I am concerned that my low water pressure will give me a poor mixer shower performance would any plumbers be able to advise ?

    cheers

    Use a boost pump for the shower.

    Do you mean keep the vented set up and use a twin impeller pump for the shower or use a boost pump on the unvented side like a salamander home boost the problem I have is that my header tank in the loft is only 25 gallons most if not all the pumps I have seen need 50 gal of usable head.
