pressured solar water heater

pressure solar water heater is a revolutionary breakthrough in the line of solar energy, as well as the symbol of a great leap in solar thermal utilization
field.

The tube has the following advantages:
1) It perfectly solves the problem of which can't run if one of the tubes is broken;
2) It prevents the tube from being easily broken caused by the volume expansion when
the water in tube freezes in frigid season
3) There is no water in the tubes, so it is successfully prevented the defects of
tubes' broken and lower power output caused by water fouling and deposits of mud and sand
4) Adopt high efficient selective absorptive coatings and low reflection ratio ensure the tube to get higher power output in cloudy weather and in moist area, especially in winter.

Features:
1) Super conductive liquid in copper heated pipe
2) Without water in glass vacuum tube, product can be used in cold conditions -30
