To set the thermostatic radiator valves.

With the room at the desired temp, listen to the flow of water through the
valve with the stethoscope. Slowly turn the valve down until you hear it
just come to a stop.

Clever. ;-)

Clever, but wrong.

Ok?

The TRV wants to be set to the point where the rad delivers the amount of power the room requires to stay at that temp, which is not trivial to measure.

Quite, so what did he do wrong that stopped that happening (and one
assumes it did happen or he wouldn't have posted the process here?),
and without any 'measurement' as such?

Bottom line ... if each rad sets each room to the required temperature
and keeps it there, hasn't the process worked?
