The solar heating, distilling, and pasteurizing system of this invention comprises an integrated distillation column-reflector-bracket assembly, a heat storage system of composite construction, and at least one evacuated glass solar collector having selective absorption. The distillation column subassembly is filled with the fluid medium to be boiled which flows into the solar vacuum tube collectors where an evaporation process takes place. A float valve mechanism mounted to the frame automatically maintains the correct liquid level inside the distillation column. The height of float valve mechanism is adjustable by means of an adjustable float bracket. The distillation column subassembly collects and concentrates the steam or vapor generated inside the attached evacuated glass solar collector tubes. The column also separates the vapor from the boiling liquid medium and conducts the vapor into a heat and distilled fluid storage system. The reflector-bracket subassembly has a reflecting panel made from at least one sheet of reflective material typically flat or formed into a plurality of substantially parallel linear troughs shaped to concentrate solar radiation ideally. This reflector also acts as a means of further stress and strain distribution and dissipation into the structural elements of the bracket subassembly.
