The heated towel rack will heat up to between 100 and 140 degrees Fahrenheit. It will not produce sufficient heat to injure you if you touch or brush up against it, though you should still exercise caution around the device. Please note that once a heated towel rail is warmed up, the surface temperature will remain constant and can't be adjusted incrementally.
The heated towel racks have a built-in offset from the wall (the size of the offset will depend on which model you purchased); the offset provides sufficient clearance to prevent any damage to the wall. You should also maintain a distance of four inches between the towel warmer and surrounding fixtures.
Additionally, nearly all of our electric towel warmer models* come with built-in TempSmart overheat protection which will shut the unit down automatically if the unit's surface exceeds the safety limit of between 149°F (65°C) and 167°F (75°C).
*Excludes the Elements model.
