An improved, portable, inexpensive solar heater for water and similar liquids. The heater comprises a tank triangular in transverse cross section, the hypotenuse of the triangular shape being closed by a wall effective to pass solar heat energy into the contents of the tank. A pivoted cover is provided for the hypotenuse wall and the inner surface of the cover is reflective, thus to augment the heat received by the contents of the tank. Preferably the tank and cover are made of shells filled with heat insulating material.
