Abstract: A solar heater is disclosed herein for increasing the temperature of water which provides a conical array of a tubular coil carried on a circular frame. Drive mechanism is operably coupled to the frame for maintaining the water conducting coil array substantially perpendicular to the impinging rays of the sun. A circular parabolic mirror is mounted on the frame beneath the conical coil array for redirecting the sun's rays passing through a central opening in the array to the underside of the water conducting coil while other rays of the sun directly strike the top side of the coil. The drive mechanism is controlled by an electrical circuit including a time clock, a motor, limit switches and several relays operably connected together to provide a controlled drive to achieve the sun-following feature.
