A solar geyser (10), especially for use in parts of the word with high levels of solar radiation, the geyser comprising a spherical container (12) housed within a translucent shell (14) and a vacuum providing insulation between the shell and the container. The container being painted black to ensure maximum absorption of solar radiation, and the geyser including an inner reservoir (30) for storage of warm water (16) and means for monitoring the heat of the water in the inner reservoir - if the temperature reaches a predetermined maximum more water is added to the outer tank. If a predetermined minimum temperature is reached the flow of water into the outer container will be interrupted to ensure that the available water reaches the desired temperature. |
