Often hear of customers claiming to be ripped off and so called heating engineers and plumbers claiming to be the pants when it comes to them being smarter than the average bear. Following story is factual. I was involved towards the tail end of the saga.
Someone I know was getting his bathroom revamped. Plumber doing the work offered to ‘look’ at the heating system that was failing to heat the rads adequately.
While the sequence may be incorrect, work was carried out be it in different order. Megna clean was installed as sediment was suspected as the root cause of radiators failing to heat the rooms. Nil improvement.
Some radiators were replaced as it was thought these were blocked. Number changed not known as did not ask the client. No improvement.
Pipes to rads were replaced which did not make any difference.
Some rads on upper floor were turned down to force heat to other rads. Made little difference.
Pump (I had previously fitted a 6m head pump) was replaced with 6m pump as pump I had fitted was said to be not powerful enough. No change.
The primaries to cylinder and heating are pumped with a motorised valve to control rads via a roomstat. A gate valve was fitted to the combined feed and vent pipe. This has now been opened fully for safety reasons. End result no difference.
Finally the householder approached me for my thoughts. I suspected flow issues in the heating zone having checked flow and return temps with dual thermometers.
The plumber was asked to check motorised valve but claimed it was OK. He took umbrage at customer seeking second opinion. Cured the problem which turned out to be the stuck motorised valve. Fitted second MV to cylinder for HW temp control. Fitted progstat for improved heating control
