Hi,

We had 'a man' round to remove the radiators in our lounge and dining room
prior to decorating as they were 'loose'. It was discovered that the lounge
radiator was cold just before this but a large amount of sludge came from
the pipe upon removal so we guessed that this was to blame (we are new in
the house so have no idea of the previous history).

When the decorating was finished, the radiators were re-hung but something
broke on the dining room rad. The lounge radiator was now working fine. A
date was made for the dining room radiator to be sorted out.

Unfortunately 'the man' forgot to come!

In the meantime, a leak appeared from a radiator valve upstairs. This was
fixed promptly (although the white 'knob' broke in the process).

Today, 'the man' returned to finish the job on the dining room radiator.
Apart from managing to empty the system into the fishpond (sorry fish!)
everything seemed to go ok. This evening the dining room rad was warm and
the lounge radiator was stone cold. We phoned 'the man' who suggested that
we turn off a couple of upstairs radiators to release trapped air. This
worked for the dining room radiator which is now hot. We then discovered
the top of the bathroom rad was only warm but this was fixed by bleeding it.

We are now left with the situation that the upstairs radiators are fine, the
kitchen radiator appears to be at about 80% heat, the lounge radiator is
stone cold (it was working yesterday) and the other downstairs radiators are
fine.

Any ideas as to what could be the problem with the lounge radiator? It's
freezing!!!!

Thanks in advance,

Daz
