The invention relates to a method for operating a system at an operating temperature of between 300°C and 500°C, using a heat transfer fluid comprising branched siloxanes of general formula (I) (R3SiO1/2)w (SiO4/2)z , in which w represents integral values of between 4 and 20, z represents integral values of between 1 and 15, and R represents a methyl group, the sum of the fractions of all siloxanes of general formula (I) being at least 95 mass % in relation to the whole heat transfer fluid. |
