<p>The method involves inserting heating elements (10a, 10b) into a filling material via openings (4a, 4b) in an envelope of a chamber of an anchoring system, where the heating elements are provided with electrical resistors. The material is heated using the heating elements to totally or partly fluidize the material. The fluidized material is extracted via the openings. A thermocouple of the heating elements is used for measuring a temperature in the vicinity of the heating elements. Thermal power, which is delivered by the elements during heating, is regulated based on the measured temperature.</p> |
