System and method for heating water with solar energy

An assembly for heating water using solar energy, the assembly comprising:

• (a) a central enclosure comprising:
• (i) an inner wall that is water-resistant and non-corrosive,
• (ii) an outer wall that is transparent, said inner and outer walls hermetically sealed together to form a watertight compartment defined between said inner and outer walls,
• (iii) an inlet port located on a lower portion of said central enclosure,
• (iv) an outlet port located on an upper portion of said central enclosure, and
• (v) a solar collector member disposed inside said watertight compartment, said member being disposed between said inner and outer walls;
• (b) an external transparent partition spaced apart from said outer wall and defining an external insulation layer of gas between said external transparent partition and said outer wall;
• and
• (c) an internal partition spaced apart from said inner wall and defining an internal insulation layer between said internal partition and said inner wall;
• wherein said solar collector member includes a plurality of apertures formed therein,
• wherein said solar thermal collector further includes shutters for shading said plurality of apertures.
