This invention relates to heaters, an ob Iocated beneath and spaced from the top ject being to provide means for utilizing wall 14 is a receptacle 17. This receptacle the heat of the sun rays for heating Water. is preferably of the same configuration as Another object of the invention is the the top wall 14 and is adapted to contain water or other liquid 18. Located within provision of a heater of this character which the is constructed of sections arranged so that housing between the bottom of the wall 30 one or more sections will be positioned trans of the receptacle 17 and the bottom wall 12 versely of the direct rays of the sun as the of the housing is a lining of heat insulating. latter travels across the horizon, together material 19. The receptacle is provided with means for directing the Sun's heat with an inlet 20 and outlets 21 and these 65 upon a receptacle or container for Water. Or inlets and outlets may be connected respec other liqui and to provide a circulation tively with a suitable source of water sup through the receptacle. . . . ply and with receptacles or the like to With the above and other objects in view, which the heated water may be conducted. the invention further includes the follow The top wall 14 is of novel construction, 70 ing novel features and details of construc inner each of the sections being formed of an tion to be hereinafter more fully described, panel 22 and an outer panel 23. illustrated in the accompanying drawings These panels are provided with openings and pointed out in the appended claims. which are surrounded by flanges 24, the 2 In the drawings:- d flanges 24 of one of the panels being tele 5 Figure 1 is a top plan view of a solar scopically received within the flanges 24 of heater constructed in accordance with the the other panel.
