There are two types of passive solar heating; a
storage tank that collects heat directly from the sun or a heater which uses
convection, known as a
thermosiphon,
to heat the water tank.
The thermosiphon uses a solar water heater panel
to collect heat from the sun and move water against gravity into an insulated
water tank.
You can see how this works in the video above
right
where a splash of red dye shows how the water circulates though
the storage tank.
