Not the OP, but indoor drying in winter at least where I live has the issue that (a) it tends to be so slow that the wash sometimes starts smelling stale, (b) it's just extracting heat from the house by evaporation, so it's going to raise your heating bills anyhow, perhaps? (c) you might end up having issues with indoor humidity, such as moldy walls.

Heat pump or condensing dryers may well be a better option.

Almost certainly the perfect solution will be situational. I mean, if your house is too dry in the winter, a bit of extra humidity might even be a feature, after all...

> you might end up having issues with indoor humidity

Winter air tends to be much drier than summer air, so much so that my bath towels dry on the rack in the winter overnight, but may stay damp for a whole day in the summer.

That said, water will condense at heat bridges (?)(poorly/not insulated parts of the wall) in the winter, causing mold, if the place is poorly insulated.

Where I lived before, that's still 80% (usually 90-95% in summer)

That's relative humidity, not absolute. Absolute humidity has an additional Arrhenius (https://en.wikipedia.org/wiki/Arrhenius_equation) factor. For instance, 100% relative humidity at 40 C is 51.1 g/cm^3, while at 20 C it's only 17.3 g/cm^3.
