This 'condom' for your geyser – invented in the Eastern Cape – can make it 27% more efficient

A bizarre-looking contraption for your geyser – closely resembling a condom – can make it 27% more efficient, according to its inventor, a young Eastern Cape entrepreneur.

Called the Hot Spot, the "geyser condom" was designed by Eastern Cape based company AET Africa, founded by 36-year-old Sandiswa Qayi. The idea for the product came from her personal need to save money on heating costs.
