Regardless of the displacement, this type of solar system works with the pressure of the water supply network on the principle of a normal household electric water heater, but instead of electricity, the water is heated by the sun.

The system consists of tempered glass tubes housed in one another. The space between them is a vacuum and allows heat losses to be minimized. They contain a copper tube in which a special fluid is heated and a condenser and a heat exchanger at the end of the pipe are delivered to the water tank made of stainless steel.
