The invention relates to a method of controlling the supply of electric power to an electric sauna heater, the sauna heater being divided into two portions to be heated separately: a stone space (1) and an air duct (2) each being provided with one or more heating elements (1A1-1A3, 1B1-1B3, 2A1-2A3, 2B1-2B3) to heat the heat-storing material placed in the stone space (1) and the air contained in the sauna room, respectively. In the invention, to achieve good operating properties in this kind of sauna heater both with respect to the heating of the stone space and the air space of the sauna room without increasing the rated wattage of the sauna heater to an unreasonably high value, one or some of the heating elements are disconnected or connected to operate at partial power, whereby the power demand of the sauna heater is always smaller than the total power of the heating elements (1A1-1A3, 1B1-1B3, 2A1-2A 3, 2B1-2B3).
