A solar radiation collector for generating useful heat in a liquid, comprising an essentially horizontal liquid infeed line and a liquid outfeed line. A heating device for heating the liquid incorporates radiation absorbing, mutually spaced tubes interconnecting the infeed line with the outfeed line, the lengthwise axes of the tubes each coinciding with a focusing axis of an associated mirror or reflector, all of the mirrors being rotatable about their focusing axis in order to focus the incident solar radiation upon the associated tube. The heating device is mounted as a unit in a completely closed hollow compartment. The infeed and outfeed lines are embedded as supporting reinforcement means in the longitudinal walls of the hollow compartment, and these longitudinal walls in conjunction with the transverse walls interconnecting such longitudinal walls form a self-supporting frame construction for the front window and the rear closure wall of the hollow compartment which contains the heating device.
