I read that as ......... Filling the header tank with water but the level in the tank isn`t rising to the point where the ball valve close`s. So where is all the water going?

If the header tank is constantly taking on water there's a leak alright. Can you isolate the ground floor circuit ( any underground pipe) and see if the circuit fills then.
If ye can isolate the ground floor totally, try putting mains water through it. This will increase the noise of the leak flushing out. You could use a listening stick which is basically a 3-4ft long steel pole with a wooden handle on top. (I know it sounds mad)
Or use a long screwdriver, place point on rad valves/visible bits of pipe etc. you should hear water noise flowing. When noise gets louder your getting closer. Failing that there are companies out there that specialise in leak finding.
If the leak is only slow and the gr floor heat works you could try running your hand around floor to see if the leak is heating the tiled floor.
Check for damp patches in walls/skirting boards warping slightly. Even a leaking rad valve dripping down to the pipes under d floor rotting them.
It's trial and error I'm afraid, good luck

Nice to see you speaking a proper language mate not that txt spek you use. lol

Suprising what you can hear with a long screwdriver as a listening bar, used it many times in the past.

Is there a drain off left open, wouldn't be the first time

thanks for your replies guys have tried a listening stick this is an old system and the building has been altered many times so there are lots of dead legs do any of you know of a leak detection company west coast Scotland/Glasgow area cheers..brum

Your best bet IMO would be to valve each level mate then you'll roughly know where your problem is

impossible to do this surely leak must be on ground floor ??
