Our system worked perfectly until it was serviced. We asked the man if one of radiators didnt get as warm because of age, size etc. He said that the system wasnt brilliant and if we turned the furthest radiator off (new) then the suspect radiator would get warmer. He did this and the warm radiator did work better. Hwever when we next turned on the furthest radiator, it will no longer work. The pipe to it is hot but all the radiator is cold. We see the man regulary and he works for a well known company and he said all of the sludge will have settled in the new radiator and that it needs flushing. Our problem is we are moving very soon and our buyer is very picky and now wants to come round to check everything works. Im annoyed because said radiator worked fine and I feel he should have warned us about this. Is it easy to flush one radiator or will the whole system need doing? How much would this cost. It is an old system with a new boiler and Im scared to mess with it as we had a few leaks when it was first fitted.
