Microsolar's Patented Coaxial Multi-valve Technology solves the stagnation problem by eliminating the laminar flow. Each collector has its own dedicated inlet and outlet valve directly to the hot water tank. The inlet is a separate internal pipe through which the colder water sinks, right to the bottom of the vacuum tube. The restriction on tube length is removed and the system performance has been maximised.

This design is state of the art. All of the benefits that vacuum tube technology brings are enhanced by Microsolar's patented coaxial system. Add to that, the parabolic concentrating reflector and it is no wonder that this new technologically superior product is the only thermosyphon device, worldwide that has ever reached 100 degrees Celsius starting from cold, in a single day.

Further proof of the efficiency of this design is that the product, which uses all of the enhancements made over the years, achieves its maximum performance almost daily.
