There are many different types of systems:
- Flat panel/flat plate systems
- Evacuated tube systems
- Thermosiphon systems
- Split pumped systems
In the Pretoria area (or any area where frost occurs), it is advisable to use a frost-resistant system. The reason is that Pretoria reaches temperatures of below 4 grade degrees celsius.
A frost resitant system is also known as a direct evacuated tube system. These systems have frost resistant properties, but are maintenance free.
