ABSTRACT:
An electric sauna heater comprising an outer casing surrounding a stone space containing heat-storing material, and at least one electric resistor provided in the stone space for heating the heat-storing material. In order to provide an electric sauna heater in which the required preheating time, the energy consumption, and the steam generating properties are advantageous, the outer casing is thermally insulated and surrounds the stone space substantially tightly at least on the sides and at the top. Electric power supply to the electric resistor(s) is effected in dependance of the temperature in the stone space so that by forming air flow connection between the stone space and the room where the sauna heater is positioned the room can, when desired, be warmed up ready for a sauna bath.
