Bosch WTB86200UC 300 4.0 Cu. Ft. White Stackable Electric Dryer. This condensing dryer vents out of a drain hose like your washer and condenses the steam into the drain. It does not vent outdoors, which means you can put it anywhere you can get a plug. It will increase the temperature and humidity where you put it. That can be ok in winter, but makes your air conditioner work harder in the summer and may increase the likelihood of mold problems. If you really want to geek out, check out this study on dryers.
