I want to relocate my existing primary circuit heated hot water tank to
another location in my house which will require me to install a 'Y'-type
system with a motorised three way valve. I've searched the Internet,
without
much success so far, to find a clear circuit diagram which will help me
complete the re-piping of the system.

Does anyone know of a good source of diagrams either on the internet or
elsewhere which will help me design my pipe circuits? I think I understand
what I need to do but seeing in a picture/diagram would be worth a
thousand
words. I am especially puzzled or concerned to know if I need to fit some
kind of bypass system around the motorised valve for either maintenance or
summer running.

TIA for any help than anyone can give me
