For a long time, your only options for in-home laundry were to purchase a separate washer and dryer. However, that is no longer the case. Combination units, which have been popular in Europe for numerous years, are now available in the United States. A combination unit incorporates both the washer and dryer into a single space-saving appliance. Further, these models eliminate needing access to a dryer vent, because they use ventless dryer technology.
When looking at a combination washer and dryer, like those available from LG, you need to remember these models do operate slightly differently from traditional laundry pairs. Because you are incorporating both washing and drying cycles in a single appliance, the complete cycle time is longer. This does require you to adjust your laundry habits, from attempting to do all of your laundry in a single day, to doing a load or two several days throughout the week.
Even though it takes slightly longer to do a load of laundry, you are provided with energy efficient features, like requiring less water to wash clothes and less electricity to dry the clothes. A combination LG washer and ventless dryer uses between 12 and 15 gallons of water, compared to 30 for a conventional front loading washer and the 40 to 60 gallons a top-loading washer uses per cycle. In addition, the drying cycle only requires 1.4 kilowatts of electricity per hour, as compared to the 5 or 6 kilowatts needed by a traditional dryer.
