Etc Solar Water Heater, Capacity : 500ltr

"slt energy offers evacuated tube collectors with either a u-pipe manifold or a heat pipe manifold. Evacuated tube solar collector uses evacuated tubes to absorb solar energy and then transfers energy to heat pipe via aluminium fin. The heat pipe vacuum tube collects heat from the sun with high efficiency and absorption up to 92% of the incoming irradiation. This allows a very simple installation and guarantees an exceptionally trouble-free operation. The manifold is mounted in a rock wool insulated box that protects the panels against heat loss.
