A solar heating system for space air heating of a building has a solar energy collector in air flow communication with underground heat storage structure. The collector has an elongated frame defining a plurality of air passages. A plurality of solar energy absorption panels are arranged in ascending space elevations in each air passage so that the air flowing through the passage transpires from the front to the rear of the panels over the length of the passage. Transparent sheet members, as glass, are mounted on the frame to cover the air passages. The heat storage structure has a plurality of concrete blocks having aligned air passages. The concrete blocks are covered with coarse rock. A pebble rock bed covers the coarse rock so that the entire heat storage structure has a large heat storing capacity. Heat insulated side walls surround the heat storage structure.
