The Evacuated Tube (EVT) Solar Collecter is the most efficient solar collectors available for solar geysers. The EVT has heating rods that use UV rays to heat the water inside the tubes.
These solar collectors work best on a pitched east/west facing roof or on any pitched roof with partial shading.
The 12 tube EVT works with a 100l geyser and is perfect for 2/3 people.
