I drew this from memory (at office at mo), so some config of some of the pipes where they go in and out of tanks, cisterns etc. may be iffy, but the principle of the layout is correct.
Vent from cylinder does go over cold water tank (although shown over expansion in error)
Not sure, but pretty certain there is a vent from primary side to feed/expansion
2 pipes drawn from f/e tank in error - only 1
This is a rough schematic so the boiler return pipe won't be higher than the tank, but shows the principle of what is there.
Any ideas??
