I hang most of my wash to dry. If I had a clothesline, I would hang even more, i.e. sheets.

If you turn the heat to LO, yes it will take awhile longer to dry the load BUT the motor that rturns the drum uses very little energy, it is the heaters that suck it down so the reduction in energy use is Huge.
In addition, no shrinkage, easier on the clothes overall, and very little if any static electricity so I do not need to use softeners or other additives, a big savings for the environment and my wallet.
Just turn the thing to LO, people!!!!

I've been using those for years. They help the clothes dry faster and more wrinkle free. My only concern is that they are made of wool, so if you're a vegan, you'll want to
take a pass on these.
