An air drier comprises a chamber in which articles are placed for drying, a blower for causing air to pass through the chamber, a heater for heating the air entering the chamber and a control circuit which includes sensors for detecting the ambient air temperature and that of air leaving the chamber. The control circuit is adapted to control the power supplied to the heater in dependence on the detected temperature difference. The control circuit has an economy switch which when operated causes the circuit to maintain the exhaust air temperature at a temperature only slightly above ambient, and a detector which monitors the power supplied to the heaters and interrupts the drying cycle when the power drops below a predetermined value.
