We have a condenser washer/dryer. It takes only small loads (compared to what we were used to in the states) and the dryer does take a very long time. But it works - has three settings of dry - "line dry" (which takes forever), "hanging dry" (which leaves the clothes just barely damp, not good for jeans but ok for cottons and synthetics), and "ironing dry" (which leaves clothes noticeably damp, but if you're going to iron them it's just fine. Also has a fan setting that only blows air.
I have had a lot of trouble with wrinkling on the "line dry" setting so I usually go with one of the next two and just make sure that the clothes are arranged so that the remaining moisture can evaporate in a few hours.
The machine also has a lot of pre-programmed settings, where you put the clothing in and it washes and then goes straight into drying mode after. It can take literally all afternoon on those settings. The machine is very energy efficient and uses very little water. The plus is that it does create a bit of heat, which warms the kitchen (where it is located) up. Saves having to pay to heat the kitchen that little bit.
