The water in a solar water heating system needs to be circulated for the system to work. Several methods are used to circulate the water within the system including pumps and the thermo-siphon principle.

Closely coupled and split solar water heating systems are two different designs that can be used when manufacturing a solar water heating system – each with its own pros and cons.

A solar collector is the device that is typically placed North facing on your roof which absorbs Sun light and converts it into heat. The heat produced by the solar collector is in turn used to heat the water inside your geyser.
