Hello all 
I have a problem which has been going on for a while and would appreciate some assistance. I shall start from the beginning so apologies for the long post.
I had a new Worcester condensing boiler installed in January 2008 after the old boiler died. It would appear the previous occupants had never had it serviced (about 10 years without servicing) so I was determined to make sure I had an efficient heating system.
I paid about £1850 which included boiler buddy being installed and a flush of the system as recommended by the manufacturer.
Since install I have had the installers back on numerous occasions, mainly to replace previously installed parts (or so they said!). Each time I have paid as the guarantee only covers the boiler.
The most recent case of having the installers back was in August last year when the radiators downstairs were taking ages to heat up and when they did were only warm at the top and not the bottom. A power flush was needed (according to them) and despite boiler buddy added and the sysem flushed on install I had to pay for this also, albeit with a hefty discount due to other admin issues which I won't go into. They cleaned the boiler buddy and added inhibitor whilst doing the power flush.
The system worked for a while, however after recently testing the system the downstairs radiators didn't heat up at all. I balanced the system and they got warm at the top but cool at the bottom again. I have tested the pump and it is on the highest setting and the spindle is rotating, however it would appear the problem is sludge once more.
I say this as 2 of the radiators downstairs have a TRV on them. I took them off and tesed the pin to make sure it wasn't stuck. I took the pin out and black inky water came out (lucky I had a towel there!). Therefore I think there is sludge still in the system.
I have left a message with the installers as I think they should be liable considering a power flush was done a year ago and there is still sludge remaining. However I don't think they will feel the same and I know that sometimes older systems as mine is can sludge up a lot very quickly.
What do you guys think the best course of action is? Do you think I need to replace the offending radiators?
Many thanks and sorry for the long post.
