PURPOSE: A device for heating water using solar heat is provided to enhance heat exchange efficiency using a long heat exchange pipe in a storage tank since the heat exchange pip is spirally formed and a fixed bracket is used, thus the heat exchange pipe is easily and firmly fixed. CONSTITUTION: A device for heating water using solar heat comprises a storage tank(6). A heat exchange pipe(24) with an injection hole(23) and a discharge hole(25) is installed in the storage tank in a spiral shape. The spiral heat exchange pipe fixes a spiral pipe to a groove using the diagonal cutting line of a fixed bracket(30).
