Abstract

It is provided an improved closed-loop solar thermi-siphon heating system that comprises a storage tank for heated water provided with inlet and outlet pipes and a heat exchanger provided within a storage tank. The heat exchanger is fluidically connected to solar collectors and is connected to an expansion vessel that is capable of receiving excess water from the heat exchanger and to discharge it back into the heat exchanger.
