These kinds of geyser systems involve panels which are situated on the roof, while the geyser tank is situated within the roof.

This kind of heating does not involve a natural thermosiphon process but requires a pump in order to move the water for heating.

These systems can either be installed as a complete new solar water heating system where it is referred to as a split pump system or converting your geyser into a solar geyser which is referred to as a retrofit solar geyser system.
