On the even larger scale why use any extra energy to dry clothes. A

er no the energy to evaporate the water has to come from somewhere.

Obviously.

In
this case the space in the house, meaning that the space heating may come
on for a bit more than it would without.

Most unlikely. The heat concerned is at high level and, in the
absence of heat recovery, would be percolating out of the house
anyway.

However that is minimal IMHO, the
biggest snag is the increase in internal humidity. A modern sealed box
house would really need to have a window or two opened or forced
ventilation of some sort (bathroom door open and fan on).

Ventilation certainly needs to be considered. Ideally this would
take the form of whole house ventilation, especially in a "modern
sealed box".
