Application August 25, 1937, Serial No. 160,907

This invention relates to solar heaters and has hood is determined by the hot water require for an object to provide a self-contained solar ments and the hood preferably comprises up heater and storage tank wherein the water is Wardly inclined glass side walls 2, glass end walls maintained at a predetermined temperature, 3 and a glass top wall 14, the walls being con electrical heating means being provided when nected together and reinformed at their inter s the Sun is not shining or when the quantity of sections by angle iron strips 5. The bottom of heated water being drawn from the system ex the hood is open and fitS air tight in a groove ceeds the quantity of water being heated by the 6, formed in a supporting base fl, best shown Sun's rays. in Figure 6.
