Abstract: A gravity driven Thermosiphon solar water heating system to harness solar insolation in low sunshine regions. This innovatory system uses CO2 as the working fluid to collect even mild sunlight to heat the water in sub-zero temperature areas. This solar water heater harnesses solar energy by fitting U-shaped copper heat removal pipes in evacuated glass tubes. This system works automatically by natural thermosiphon circulation force caused by density difference of supercritical CO2 at different temperatures. This innovatory solar water heater can perform in ice cold temperature areas where water based systems cease to function after freezing.
