This is a passive system that works on the principle of density difference to transport heat energy. Potable heat transfer fluid (i.e., water) is heated by a solar collector and the natural convection drives the water from the solar collector unit to the hot water storage tank unit. Water becomes less dense due to solar heating and expands according to the temperature rise. Hot water is circulated to the storage tank, and the relatively cooler water from the bottom of the tank is circulated to t...
