Solarmat

A solar heating system, comprising:

• a solar heat exchanger having a first thin film, a second thin film of similar dimensions to the first thin film, and bonded to the first thin film at the edges, a mesh position between the first thin film and the second thin film, inlet means for permitting a fluid to enter the space between the first thin film and the second thin film filled by the mesh, and outlet means positioned such that fluid flow through the mesh covers approximately the entire region between the first thin film and the second thin film for permitting said fluid to flow from the space between the first thin film and the second thin film, whereby said fluid may be drawn by suction from the inlet means to the outlet means and solar radiation impinging on the first thin film is transferred to said fluid;
• a pump having an inlet port connected to said outlet means of the solar heat exchanger and further including an outlet port;
• regulator means connected to said outlet port of the pump and also connected to said inlet means of the solar heat exchanger for controlling the pressure of said fluid at said inlet means of the solar heat exchanger;
• a reservoir for receiving said fluid flowing from said outlet port of the pump;
• and
• second regulator means connected to an outlet from the reservoir and further connected to said inlet port of the pump for regulating the pressure of said fluid at said inlet port of the pump so that sufficient suction is created at said outlet means of the solar heat exchanger to draw said fluid from said inlet means to said outlet means of the solar heat exchanger.
