2. Lack of information
I have 12 radiators in my heating system - 7 on first floor and five on ground. floor. No water in first floor radiators hence the panic.
I have checked and found plenty of water in the header tank and the ball valve is ok. I tried to drain water from the lowest outlet but the header tank water won't drain. I assume this is due to blockage of the 15mm header tank feed pipe, where it connects to the 22mm pipe before the circulation pump - located in the airing cupboard.
Can't run heating as circulation pump heats up, presumably for lack of water and the boiler cuts out.
Am I right in assuming location of blockage?

SOunds like it. A water-vac on the vent might clear it enough, or mains applied to the feed pipe from above.
Pro tem you might be able to fill via the drain point. Tends to need 2 or 3 people watching turning on and off and yelling.
Woos way to do it is remove a radiator and connect via washing mashine hose to a wm tap. (they come 2.5m and are easy to join).
Do search on "combined feed and vent".

Sounds like trapped air lock in system. Try draining and refilling to try and shift it or cranking open rads on the big nut ends as oppossed to the bleed screws, sometimes shifts an air lock. Also vent pump.
The assumption that the cold feed to CH system was blocked was proved right. Took me three hours to unblock the feed and the heating is now working perfectly.
