AET AFRICA innovates, manufactures and supplies energy efficiency products for water heating and cooling systems and also conducts research on innovating those technologies. The company designs innovative products that would reuse wasted heat, provide accessibility and affordable hot water to all households and commercial users and further pasteurises the water.

AET developed a technology to decrease electricity costs of water preparation through a hotspot, without replacing conventional geysers. The hotspot compliments geyser timers, geyser blankets and high pressure solar geysers.
