OK here are my details
Mexico Super 450FF Conventional floor standing boiler in kitchen (with pump located inside boiler housing)
Hot water tank located in bathroom directly above boiler
Two tanks in the loft, one smaller than the other.
Smaller tank has a ball cystern and an overflow pipe (wrapped in polystirine)
Larger tank has a ball cystern and is made of black plastic
Recently the upstairs radiators have stopped heating up fully, the lower part of the radiator has some heat but not much. I have tried bleeding these radiators, initially some air comes out, then it stops and there is no water or air.
The smaller of the two tanks in the loft (I guess this is the feed and expansion, or fill and return not sure to be honest) has a lot of brown sludge in it, which is quite disgusting. The water level is above the ball cystern, and to be honest it doesnt look like it has gone below the ball in quite some time. Also I have noticed that the overflow pipe that is routed outside has started to drip, where it never used to at all.
When the heating kicks in, all the radiators make a lot of sloshing water noises and the boiler also makes this sloshing sound (this goes away after a while, maybe 5 minutes or so).
The downstairs radiators seem fine. I had these balanced quite nicely, but now the upstairs radiators are not heating up, no amount of balancing seems to make a difference.
I tried to switch off all radiators in the house, with both the adjustable dial and the locksheild, and then turned the heating on. Wierdly the boiler would not fire up at all unless at least one of the radiators downstairs was opened up at both ends. No idea if this is related, but I thought it was a bit wierd.
Anyway, any help would be much appreciated.
