Yet again I hear you cry but I have read all the previous strings,
chacked the flow (no thermo valves), bled all the rads, lagged the
But I still have a radiator that chimes like big ben when the heating
comes on. I am convinced it is inside the rad so can it be some
restiction? They rad is about 30 years old I guess and it dings every
minute or so.
Have to cure or else no wife-hmmm!
Have you considered the wall brackets?
The radiator itself will expand (especially if it is a long one) and the
brackets on the back of the radiator, which drop onto the wall brackets, may
well want to move a little along the wall brackets.
Modern wall brackets have little plastic inserts on which the radiator
These should allow silent movement.
Your wall brackets may well not have these, or they may be worn out.
If this is the problem, I presume you will have to get some new wall
brackets with the plastic inserts, unless you are very lucky and they fit
your 30 year old brackets.
Either way, it will be radiator off wall time.
P.S. just considered that a spray lubricant (oil based or rubber/PTFE spray)
may provide enough short term slippage to change the 'ding' or eliminate it.
This would at least confirm the diagnosis.
