In order that the energy consumption would be low, the stones in a stone space (11) of the stove are first heated to a desired temperature by circulating air within the stove by means of a fan (5) as a closed forced circulation merely through the stone space (11). After the desired temperature has been achieved, the air is begun to be circulated by means of the fan (5) as an open forced circulation through the stone space (11) and the sauna room. |
