Dryers are an important household appliance, and often one of the most used. They can quickly dry your clothes, so you don’t have to wait as long for them to air dry. Not only are they convenient, but they can also save you a lot of money on your energy bill. Most people think that because they’re not doing any damage to their clothes, they can just leave the dryer on indefinitely. This is not only wasteful, but it’s also dangerous. A dryer that’s left on for too long can easily overheat, causing a fire.
