Solar Water Heating
Thermosiphon Systems are where the tanks are installed on the roof. The pressure created by the hot water drives the water up into the tank.
Although some people might find them not visually pleasing, they are about the most effective systems.
Split pump systems have the tank inside the roof, and will have a pump that drives the water down into the tank.
Often used on new builds, as well as where when there are restrictions of placing tanks on the roof
A retrofit system is the most cost effective option of installing a solar geyser.
The original geyser is used and a panel is placed on the roof. A pump will drive the heated water from the panel down into the geyser tank. Normally used when the existing geyser is in good working condition, and not older than 7 years.
There are two options of collectors available for solar geysers.
EVT(evacuated tubes) and Flat Plate. Both have their pros and cons.
Evacuated tubes is a slightly newer technology, and lately have been found to be more efficient in water heating.
While the Flat Plate systems have a longer plant life and are more durable to the elements
