Replace double radiator with Single (too powerful for room)?

[RajaStyle]

Is it worth replacing a double radiator with a single one with the same dimensions ?

The current double radiator in the spare bedroom is very powerful and makes the room stuffy.

The bedroom will be used by my little girl after winter and I was thinking of replacing it with a single radiator, however couple of people have told me to just keep the double and turn the thermostat valve down to half.

Is this effectively the same has having a single radiator ? or is it more efficient to put a single radiator if this double will never be utilised fully. Any advantages or disadvantages over either ?

Thanks in advance

As long as the TRV works keep it as is.

That is right - the double will bring the room up to temp. quickly and the thermo valve will hold it there- unless it needs a new valve
