If it has been a while since you purchased a new dryer, there have been changes in technology, so that you no longer require a dryer vent, like with LG ventless dryers. Vented electric drying is not very energy efficient. It requires drawing in room temperature air, passing it over a heating element to the preset temperature, and them releasing it into the drum to help remove moisture and dry the clothes. Once the air leaves the drum, it is forced down a dryer vent rather than being recycled and reused. This process has to start over, with more air being drawn in, heated, and so on, which uses a large amount of electricity.
Recycling Air Is a Key Feature of Ventless LG Dryers
One of the key features of ventless drying is recycling the air and reusing it to make drying cycles much more efficient. As a result, you end up using a fraction of the electricity to dry your clothes with a ventless model than a conventional vented dryer. It should be mentioned there is a noticeable difference in cycle times, where ventless dryers run for a longer period of time. However, this does not mean they are using more electricity. In fact, the increase in cycle time is the result of the complex recycling processes and the way moisture is extracted from your clothes.
