A shallow tank which is inclined when the unit is in operative position and having a relatively large surface to face in the direction of the sun, and a wide tube or a plurality of tubes extending over this large surface and communicating at one end directly with the interior of the tank near the lower end thereof and communicating at an opposite end directly with the interior of the tank spaced above its lower end, thermosiphon circulation being maintained as liquid in the unit is heated by the sun when in the tube or tubes and flows therefrom into the tank, down through the tank and back into the tube or tubes. It is preferable to provide an insulation shield over the end of each tube which directs liquid into the tank.
