Radiators, makes house smell nice too. Need to think about a dehumidfier though, we don't have one but don't seem to suffer I'm crap at washing lines, forget to get it back in and then it gets wet
Either washer dryer obviously, or get a rack from Ikea, I got quite a decent one recently, was about £22. It folds flat but once up its huge, I just stick that in the spare room or the main bathroom, mostly the bathroom as our spare room is also a study.
