A closed container which consists of metal or plastic and has heat-conducting ribs is provided with a feed valve. The heat-conducting fluid "heatboron" is later on filled into the container via this feed valve. To heat the container by means of the heat-conducting fluid "heatboron", an electrical heating rod is introduced into the container. A ventilating fan having a motor is mounted for the heat transfer to the ambient air. The entire system is enclosed by an outer housing. A thermostat is attached to the housing and is connected to the electrical heating rod and to the ventilating fan. An electronic controller is additionally mounted to control time and temperature. |
