A solar collector having the shape of a step pyramid which is enclosed within a transparent dome and a bottom insulating layer. A continuous coil of tubing conforming to the same shape as the step pyramid is in contact with each successive step. Because of this shape, the collector receives solar radiation during all daylight hours without the use of mirrors or tracking devices.
