The water is circulated between tank and tubes by a German-made circulation pump which is regulated by a solar controller.

Neopower tubes consist of an inner and outer tube sealed under vacuum, using 2 mm glass. This type of tube is exceptional good quality for its reliability and performance. Extra large heat pipe condensers (24 x 90 mm) are used to achieve high efficiency.

Within the Neopower vitreous enamel tank, super thick fluoride-free polyurethane froths evenly under high pressure so that it has great performance of retaining heat. The quality anode magnesium rod is made according to Germanic DIN4753 standard and provides efficient corrosion protection for the tank.
