<p>The device for producing hot water by means of solar energy is comprised of flexible plastic sheet material, welded along the edges thereof, so as to form a flat collector. Two medium sheets (3, 4) form a flat container (5) for absorbing the water to be heated. They are fixed one to the other at a regular distance. Two outer sheets form the outer walls (1, 2). Two intermediate layers (6, 7) formed by plastic section sheets, act as struts between the container (5) and the outer walls (1, 2). </p> |
