Yep you tee in the hot water return to the c/h return as close to the boiler as poss, well after any radiators, this should prevent reverse circ.

Ive just completed my nvq level 3, back in next week for my ACS, how you finding it?

when you say hot water return do you mean secondary circulation via a seperate pump

No. It's the return from the HW cylinder coil.

Go to the Grundfos site and look up the three tee rule.
