At which point I become confused again. I do have a cold water tank in
the loft - i was under the impression this was a sign of a gravity fed
system?

Think a gravity system is where the hot water circuit isn't pumped. If
you've got motorised valves etc, it probably is.

You can have a C plan set up where the boiler/DHW cylinder circuit is
gravity (meaning convection) and a zone valve and thermostat are used
to prevent the hot water from overheating.
