A solar heating system adapted to provide heated air and water to a building structure with simple yet efficient components. The solar heating system comprises an air heating chamber which is exposed directly or indirectly to radiant solar energy, and air heated therein is directed to a heat exchange tank. The heated air from the air heating chamber is directed through bubble producing means, the bubbles rising through water contained in the heat exchange tank. Upon escaping from the heat exchange tank, the air may be directed to any one of three locations; firstly, the air may be directed back through the bubble producing means and into the water in the heat exchange tank, secondly, it may be directed to a building structure to provide heated, humidified air, and thirdly the escaping air may be directed to ambient atmosphere. Perforated baffle members having perforations nominally smaller than the bubbles emanating from the bubble producing means are present within the heat exchange tank to cause a circuitous upward path for the bubbles, thereby increasing the heat exchange between the bubbles and the water.
