gravity fed pumped system

[lisagav]

hi all,

i have an old central heating system which has very basic controls and i'm getting fed up of having to put the heating on to get warm water.

is it possible to install a 3 way valve and a new controller somewhere in the system so that i can choose if i want water or heating.

thanks in advance

There is but without seeing the locations of everything and the orientation of the pipes it will be dificult to give accurate information.
