I drained down my central heating system to fit thermostatic valves on all of the radiators. When I came to refill the system via the Boilermate II thermal store I had great difficulty. There is water in the fill/expansion tank but none in the main body of the thermal store itself. I eventually managed to fill the downstairs radiators but can't fill the upstairs ones or the tank. Any suggestions please?
Can't refill a Boilermate II

Sounds like the cold feed is blocked.........A near on impossiblity to unblock on a Boilermate II.
I have in the past cut a hole in the header tank and using a 22mm tank connector run a 22mm pipe. Removed the drain off from the cylinder and connected the new pipe into this connector using a tee with a drain off on. This restores a cold feed to the cylinder in 22mm thats not likely to block and can easily be unblocked if it does.
Id also recommend at least 4-5 litres of inhibitor when filling back up.

I have exactly the same. Yesterday system was drained to attempt repair to boiler. On trying to fill back up overhead (filler/expansion) tank is full of "silt" which has seeped into (and blocked) cold feed to main unit .

I would also fit a Magnaclean filter on the CH return pipe to the Boilermate. Essential I would say.
