Solar Collectors

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.

There are various types of solar collectors on the market and the two most popular types are:

Evacuated tube collectors
Flat plate collectors

Closely Coupled vs Split Systems

Closely Coupled

Closely coupled systems are the solar water heating systems where both the tank (geyser) and solar collector are on the building’s roof. The tank is typically mounted horizontally above the solar collector. In some instances, the solar collector and tank are integrated to form one structure.

The water in a closely coupled system is heated by the solar collector and circulated into the tank using a principle called thermo-siphon. In short, thermo-siphon uses the property where hot water rises and cold water sinks.

Split Systems

Split solar water heating systems allow for the tank to be placed inside the roof – improving the aesthetics of the solution. Split solar water heating systems either use thermo-siphon or pumping to circulate the water within the solar water heating system.

Solar Water Heating | Domestic | Commercial | Industrial

Solar water heating can be used in many different applications such as domestic hot water systems, commercial water heating systems, and industrial water heating systems. Solar water heating makes use of the sunlight received on earth during the day to heat the water. The hot water produced by a solar water heating system can be seen as ‘green’ as no carbon gases were emitted into the atmosphere in the process of generating the energy.

There are many different types and combinations of solar water heating systems on the market today. Some solar water heating systems use flat plat collectors, others use evacuated tubes solar collectors, some use solar pumps for circulation where other use a principle called thermo-siphon – where hot water rises and cold water sinks.
