I had a washer cum dryer once and it wasn't very useful. I think it was an Ariston. Even if you put it on the maximum dryer preset mode, the clothes are dry only if you have half load or less of laundry. If you split your laundry into many separate small loads, you end up using so much more electricity and water. If you have a big load to wash, then it comes out still slightly damp. Clothes are also quite crumpled after the dryer and I end up spending more time & energy ironing out all the creases on clothes. Dryers also wear out the clothes, especially soft t-shirts - shape will run a bit, and it becomes more worn-out, like "nuah" and faded/furry. Some clothes even shrink. Definitely consumes quite a lot of electricity. However, this was for a washer cum dryer. I have used a unit which is just for drying only (used it overseas), and that worked really well - clothes are dry and not crumpled. But that was a large, almost industrial type of dryer. Can even dry comforters.
