The construction of this electric sauna heater requires a particularly small safety distance. Depending on the model size, the necessary distance from the wall is 6–12 cm. The heater also comes in a slim wall-mounted version. This space-saving functionality is made possible by an internal air channel which provides optimal ventilation, accelerates the heating process and extends the service life of the heating elements. In terms of its external appearance, the combination of metal and stone elements gives the heater an elegant look.
