Hi all,
I had my TRV's replaced (and lockshields) on two radiators in the summer and over the last couple of weeks (since starting to use the central heating after the end of summer) I have noticed that the radiators (which have he new valves) are very temperamental. The other radiators work fine.
I have noticed that they haven't been getting warm when the central heating is on, so I change the setting on TRVs from 3 to 4 and this slight change suddenly forces a gush of hot water through the rads - making them very hot to touch. The pipe work throughout the house then seems to 'gush'.
An engineer has been out and apparently rebalanced the radiators but still have the problem.
Sometimes I have also noticed that the pipes around the boiler make considerable noise so much so that I turn the system off.
Is there a blockage in the pipes somewhere? An engineer did put a magnet on the cold feed and it was attracted to the pipe so there could be a slight blockage of sludge etc. Would this explain why a slight change in the TRV forces hot water through radiator? Or is it simply a balancing issue??
Any help appreciated.
