The time you save drying laundry on the radiator will, in the worst case, be your undoing. The dried garment can cause heat build-up.
This increases the likelihood that the laundry will ignite and cause a fire.
If you have a towel radiator in the bathroom, you don’t have to worry about it. The rod-like shape, which is specially made for this purpose, prevents heat build-up. So you can let your laundry dry on it with a clear conscience. A nice side effect: since the towels dry particularly quickly on this type of radiator, the room climate in the bathroom does not become too humid and can prevent mold from forming.
