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...
