The thermal characteristic of a new type of vacuumed fractal solar collector (VFSC) is derived and evaluated in this paper. Its heating capacity is estimated based on the fractal arrangement of toroidal absorbers on a parabolic concentrator. The total coefficient of thermal losses in the VFSC is determined with minimal solar energy. At the same time, the absorbers in the VFSC are designed fractally from toroidal polymer pipes located in a vacuumed parabolic space. The possibility of working in the VFSC in non-stationary thermal modes with zero water consumption and minimal solar radiation is shown. In addition, the transmission and absorption capacity of the VFSC is estimated. It is noted that according to the results of tests in the forced mode of heating by solar radiation with zero water consumption, the helio device showed positive results.
