Gravity hot water central heating system

Hi terry,

I have recrently replaced my direct hot water cylinder with a indirect cylinder and re-made all the pipe connections to allow for a expansion tank and overflow pipe. The problem is the gravity hot water no longer reaches the tank from the boiler even though the pipe is 28mm?
Can I add an additional pump on the return to boost the flow.
