I assume you typed hot water & hot water + heating but forgot the space between words so the swear filter starred it out.

Sounds like a y plan but using the internal boiler thermostats to control temperature of hot water & heating.

hi all
just to let you all know that it is sorted.
in the end it was just a y plan but because of the lack of a tank stat the mid positon wouldnt work!
fitted one and wired the heating through the hot water satisfied terminal on the tank stat and bingo.
