PURPOSE:To improve heat collecting efficiency by a method wherein very small amount of air bubble is blown into the water heating vessel of the solar heat water heater to utilize the effect of disturbing hot-water due to the natural ascending force of the bubbles. CONSTITUTION:When the sunshine has arrived at a predetermined strength, a photosensor switch 5 is operated to operate an air pump 3 and force the air bubbles 4 into the solar heat water heater 2 from the lower side thereof. The air bubbles ascend naturally along the right receiving surface of the water heater and leave to the outside of the water heater. According to this method, the air bubbles contact with the light receiving surface during ascending and disturb hot-water to promote the movement of heat whereby the heat collecting efficiency may be improved. |
