The pipework doesn't really influence this.


I was thinking of a electrolytic scale inhibitor which is fitted in

I am afraid so.

If you do a Google Groups search on this newsgroup you will find that
this subject comes up about every month to two. We have one
individual who has one of these and claims that it works. He is in a
minority of almost one. Pretty much everybody else who has bought
one reports no, little or inconsistent results.



The only completely effective solution to this is to install an ion
exchange water softener. That will provide softened water for as
many outlets as you like. You then normally leave one cold outlet
(kitchen tap typically) as a direct supply from the mains.

This would have to be fitted to the incoming mains ,before it
branches off to the hot water tank and mains fed cold ?

It can go where you like, really. If you just wanted to cover the
shower then you would need to soften the cold water going to it, plus
all the hot water unless you had separate water heating for the
shower.


You could arrange for the plumbing just to feed the shower with
softened water, but it seems a bit pointless when you could cover the
entire house.


It not a house its a lareg geogian building whith over 20 bedrooms.
so it would be quite a major operation. The scale is not bad in the
other rooms.

This does make it difficult, because you also have the running costs
from the use of salt in the softener.
