EKS 3 Storage Heat Evacuated Tube

A revolutionous system desinged to replace common hot water tanks by a storage vacuum tube.
The principle is fascinating like a transparent hot water bottle. The sun radiation is transfered directly to the stored water and the stored water is vacuumisolated.

EKS 3 is a storage type evacuated tube, having a special stainless steel container inside the evacuated glass tube. The container serves a double function in that it absorbs solar radiation at the same time stores the heated water for domestic use. This container is allaround coated with Al-N-O on its surface.

EKS 3 tubes can be connected directly to the water supply or mains circuit and serve as a water tank. It eliminates the need for heat transfer fluid.
