Gravity hot water system ?
Quite common as heat rises, you can trap the central heating flow to stop this. As heat rises, if you drop the flow down before going up, the heat cannot rise naturally.

if it is fully pumped system it would most like be the heating zone valve passing or the 3-port valve passing.
It could also be reverse circulation, but it is unlikely, as if it were it would have been present since the day it was installed

Well what type of system do you have ?
Fully pumped or gravity hot water ? can you have central heating on by itself ? or only with hot water ?

easy cure? yeah, turn all the radiators off! :P
Your local engineer should have no trouble correcting the fault, unfortunately i can't give any other advice without any details of your system.
