Working Principleï¼Âš

The vacuum tubes absorb the solar energy and transfer into the heat energy, then pass it to the U pipes. U pipes conduct the heat to the water.. The circulation pump makes water circulate every now and then. And each time the water circulates through the header pipe, the temperature is raised by 5-10 degree. There is no water in the vacuum tube, so the tube will not break in the winter. It can be still operate in the event of occasional tube breakages.
