Having lived in both Norway and England, Norwegian houses are much warmer and drier indoors during the winter. Every house in England I lived in was damp, basically uninsulated and had terrible heating systems.

London has an interesting climate - despite being fairly far north it doesn't get that cold in winter. It is common there to not have whole house heating. Norway isn't far London, but it is enough worse a climate that pretty much everyone has some form of central heating and keeps their house warm year round.

For this discussion is means that in London the indoor climate is livable, but terrible for trying clothes, while in Norway the indoor climate is nice and drying clothes indoors is helpful for adding humidity.

> I lived for years in Paris. Dryer don’t exists there. You just don’t have space for one … Is the weather THAT different in London ?

Do you not have space for a washing machine either? In many apartments in the US the dryer is stacked on top of the washing machine. It doesn't consume any additional space.

Dublin is pretty similar culturally and climate-wise to London.

People use combo washer-dryers.

Shouldn't be if your building was designed properly, with a proper Heat Recovery Ventilator (HRV) e.g. [0]. The long and short of it, fresh air is slightly heated by stale outgoing moist air.

We're in central Europe. A few degrees colder than London in Winter, I doubt it matters. I've done it in houses built a hundred years ago (though they were modernized since, obviously) and ones that were build recently with high degrees of insulation (almost but not quite passive). Not an issue. I usually did open the windows for a couple of minutes.
