Back boiler plumbing circuit

[Japnut04]

Plumbed this up last week an having a problem with it, the gravity flow from the stove works fine, its just when the pump for the stove kicks in the return from the rads seems to go up through the coil instead of back to the stove, put a gate valve on the return link which helped but still not right, its cooling the hot water in the cylinder every time the pump runs, cheers for any advice giving.

are both boilers feed from the same cistern in the loft to give the same head?

I only have the back boiler side fed from the f+e tank at the minute didnt get around to putting in a new pipe for the ch side of things

you should have used a injector tee on the stove you would have no problem
