HOW PRE-HEATING THERMOSIPHON WORKS
1. Cold water enters your solar geyser straight from your cold water mains.
2. Cold water is drawn down into the solar panel. As the cold water moves through the solar panel, it will gradually heat up, making its way back to the geyser as warm water. This process continues, slowly heating the water up throughout the day. This process is called “thermosiphoning”.
3. As you open your taps to draw water, you will draw water from your existing (or primary) geyser. With standard geyser installations, once you draw water from your geyser, it will fill up with water from your cold water inlet. With our preheater, this is not the case. Your primary geyser will fill with hot water from your solar geyser, significantly reducing the need for your electrical element to kick in, saving you money on electricity.
