A single cup electric heating device for heating a cup of tea, coffee or the like includes a generally vertically oriented mounting support having a flat rear surface adapted to be mounted on the wall of a motel room, hotel room or the like. The mounting support has a horizontal cup holder at its lower end for supporting the cup to be heated. Cooperating guides on the cover and sides of the mounting support slidably guide the cover for shifting movement between a raised position permitting a cup to be placed on the cup holder and a lowered position covering a cup so placed. An electric immersion heating element carried by the cover is immersed in the contents of the cup when the cover is in the lowered position and is energized by cooperating electrical contacts on the cover and mounting support which engage in the lowered cover position. An electromagnetic retaining mechanism simultaneously energized with the heating element retains the cover in its lowered position. A thermostat in the cover responsive to the temperature of the cup contents simultaneously deenergizes the heating element and retaining mechanism when the cup contents are heated to apredetermined degree and a spring returns the cover to its raised position.
