Ah that makes sense, will give it a try and update.

Hi D_H, yes I did turn the rad upside down and I gave it some welly with a rubber mallet. I think the neighbours thought there was a tone deaf steal drummer in the garden. What do you mean by no.1 remove all trv heads and set all wheel valves to fully open? Do you just mean turn the valve...

Well what a day today has been! From the previous posts, the idea today was to remove the rad in question, flush out, replace and then balance all the rads. I closed the valves either end and then proceeded to undo nuts to remove rad. The nut near to trv was a beast to undo and resulted in too...

Thanks for the valve tip D_H I will try and find something suitable before I tackle the problem :wink:

From details and advise given so far are you of the opinion that this is likely to be a blockage rather than a balancing issue? If so I guess I know what I will be doing this Saturday. Thanks for everybodys input so far.

Hi Jackthom, What is the bucket test and what should I be looking for if there is a problem? Following the advise given yesterday, with all the other rads turned off the problem rad got hot around the edges and along the top (could only leave hand there for about 4-5 secs) but in the middle...

I closed all rads except for the dodgy one, it did get hot but only around the edges and along the top the rest of the rad was quite warm but nowhere as hot as sides and top. Does this sound like a balance problem or build up of sludge?

Hi Tony, When you say is the system balanced I assume that it was originally and I have not done anything to unbalance it. On the rare occasion in the past when I once removed a radiator for decorating purposes I made a point of how many turns it took to close the lockshield and then opened...

When you say turn off all the other rads do you mean just from the trv's or the lockshields also? Hope that's not a daft question but thanks anyway.

We have 8 rads on our system, 5 upstairs and 3 downstairs. Each rad downstairs is on an inverted loop. All the rads get hot except for the one in our dining room, which at best only gets luke warm at the top. I have read various posts of similar problems and the answer would seem to be a build...

Thanks for your advise anyway D_H. Will have to see what the engineer uncovers on Friday.

D_H - Yes, the valve did seem to pass all your tests, however, when I tried it again this morning for a short while, when the programmer came to the end of its timed cycle the lever on side of valve did not revert back to the W position. I turned it off from the mains again and then the lever...

Well I followed the instructions given by D_H and it did seem to reset the midpoint valve. However, when I turned on the system again I still got no heating or hot water? The boiler stat was set to high and did fire up initially but did not remain on for too long. I did not leave the system on...

Hi D_H, thanks for the advise. I will give this a try this evening when I get home. Will report back with my findings.

I have an open vented gravity fed system operated by a baxi bermuda 401 back boiler and trv's on all rads except one. About a week ago I bled a couple of rads but with the central heating on :oops: . That evening I came home to check if rads were ok and found that none were working. My initial...
