I have a radiator which is making a whistling noise - however when we
tweak the knob / temperature control, it disappears.

What is the problem and how do you solve it?

Many thanks,

Some thermostatic radiator valves just do this, unfortunately.

It can also arise if the valve is intended to have the flow in a specific
direction (marked with an arrow on the chrome part of the valve) and
it has been fitted the other way round.

These days, most can be fitted either way and there is a two-headed arrow
to designate that.

So the short answers are to check the arrow and flow and if wrong, reverse
the valve, or failing that to replace it.

You can work out flow direction by seeing which end of the radiator gets
hotter first.

Change the valve then
