●This type uses the all-glass evacuated solar collector tubes as
the heat-absorbing element. The high vacuum degree of the clearance
between the outer and inner tube reduces the heat emission which is
caused by convection and conduction. The layer films (coating) of
the all-glass evacuated tubes transfer the sun energy into heat
energy. The high absorption and low emittance rate of film is
unique.
●Using thermosiphon system- Depending on the different density
between hot water and cold water, a water flowing cycle is created
in the tubes. Hot water flows antomatically upwards while the cold
water flows down. The water in the storage tank will be heated from
this nautal circulation.
