The main objective of this paper is to introduce the concept of novel flat plate solar geyser with integrated heat exchanger and open loop passive system.The heat exchanger acts both as collector for solar radiations and as a heat exchanger its self for cold water beneath it. Contrary to the conventional flat plate solar collectors, water is in direct contact with the collector or flat grooved heat exchanger. A safety control box is installed to minimize hydraulic pressure of cold water reservoir on the flat grooved heat exchanger as contrary to tube a plate cannot sustain high pressures. The heat exchanger has circular grooves which adds in sustaining hydraulic pressure, increase heat exchanger exposed area to the sun and also cause turbulence in flowing cold water to increase heat rate. A special exit system for hot water is used having a float tube which enable user to withdraw hot water without pressure of cold water from cold water reservoir.
