The earliest clothes dryers were made in England and France in the late 18th and early 19th centuries. Known as “ventilators,” they were large metal drums with ventilation holes, powered by hand cranks and used over open fires which resulted in the clothes always smelling of smoke, often being covered in soot and sometimes catching fire!
Gas burner tumble dryers are much more cost effective than electric units and are becoming more popular for use in the home, usually they are found in laundries.
Physicist Davis MacKay weighed his laundry and discovered that a typical 4kg load of dry washing emerged 2.2kg heavier. Even after vigorous spinning in a modern washing machine it’s not surprising it takes so much energy in a tumble drier to remove all that water!
The data we use to work out energy and water costs come from a range of reliable international sources to give an average figure. Figures are rounded up or down to the nearest whole number.
