We've got a condensing drier [1] but being part Scot I can't bring myself to actually use it more than three or four times a year. We've used it once, I think, since Christmas. We have an airy-fairy[1] in the stairwell with an old desk-fan screwed to the ceiling to make an indoor breeze for when it's slow to dry. Does a full load overnight at the slowest, usually in nearer three hours.
[1] From the local dump nearly nine years ago, broken but easily fixable. [2]

only it wasn't nearly that expensive.
