Not all Europeans use a drying rack indoors. In the Netherlands only the poor do this. It takes a long time and doesn't even save any energy as the water from your clothes makes your entire house humid and feel cold in the winter.

Shrug we've been mostly using them, they seem to work well enough.

I'm familiar - however it's slow. What do you do if you need your clean clothes to be dried quickly?

Buy merino wool clothing, it dries very quickly :-)

It's time to heat pump

Yeah, though the heat pump dryers I've seen don't sound like they perform very well for some reason. I need to look into it more.

Heat pump water heaters, though, are supposedly much better than resistive.
