The method involves calculating portion of flow of fluid via fluid paths (2, 3) from temperature measured by temperature sensors (5-7) that are arranged in a collection line (4) and in each of the fluid paths. The fluid paths are designed in form of co-axial coils. Reference ranges for a portion of flow of the fluid in the fluid paths are stored. A warning is delivered, during calculation of the portion, which is found in a limited range of the reference ranges. A heating system is switched-off, when the calculated portion is found above the limited range. |
