A heat collecting apparatus is provided to absorb maximum volume of solar heat by rotating a solar heat collecting plate periodically in accordance with the electrical signal transmitted from a control board. A heat collecting apparatus includes a solar heat collecting plate(10), a rotating unit(30), a solar heat absorbing pipe(20), a hot water tank(50), and a control board(40). The solar heat collecting plate collects and reflects solar heat. The rotating unit rotates the solar heat collecting plate. The solar heat absorbing pipe absorbs solar heat from the center of the solar heat collecting plate. The hot water tank reserves hot water heated by solar heat. The control board operates the solar heat collecting plate for absorption of solar heat. The solar heat collecting plate has a concave disk shape having an inner surface attached with a reflection plate(11) and a center with a through hole(12) for insertion of the solar heat absorbing pipe. The solar heat collecting plate has a rear surface equipped with a bracket. The solar heat collecting plate is tilted at the angle of approximately 15 degrees onto a pole(60) through a connection shaft. A larger gear(31) is engaged with a smaller gear(32) fastened onto a shaft of a motor(70) fixed on one side of the pole.
