Water inside vacuum heat- collection tubes; since the hot medium inside vacuum tubes floats up and cold one goes down due to respective specific gravity, hot and cold mediums convections up and down to cause the heat conduction, furthermore transfer the heat to the related working medium in the heat tubes, the working medium sorbs the potential heat and becomes steam to rise up to the condensing section from the tube heat evaporating section; it emits the heat in condensing section to change again into liquid working medium; it flows back to evaporating section under the gravity action, the emitted heat is transferred into the water inside water tank or tube group by means of the heat-conduction through heat tubes condensing section; it makes the cold water in water tank into hot water in the repeated way.
