If you have city central radiated heating, then making the radiators less effective is just a bonus of getting your clothes to dry a bit faster.

I'm not sure how common that is, the only place I have heard of it is in some Scandinavian countries but if you know otherwise i would love to hear about it.

All of northern china is like this. I'm sure much of Russia is also, its a pretty common thing spread by the soviets (socialized heating....).
