Thermal Solar Tube

06 25th, 2009

Solar water heating was done by flat panel solar panels. Featuring a copper coil that was sitting behind a glass panel that was pre-heating the water in it during the sunny days and was cooling off rapidity during the night or cloudy weather.
All this is now history. With the invention of the
Solar Thermal Tube also called Evacuated solar tube.

Please click on the image and let me explain how a Solar Thermal Tube with heat pipe works.

Components are:
-Double layer Glass tube that holds a vacuum for very little heat loss.
- Acetone gas filled copper heat pipe to transfer heat into the water holding tank.

Some of the benefits compared to traditional flat panel solar water heaters include
a good insulation against cold weather with the vacuum filled space between the glass. With this the outside temperature has no effect on the inside heat and the heat of the water that the thermal tube is heating.

In addition the round shaped evacuated tube catches the sunlight at a more direct angle any time during the day for maximum “sun-ray-harvesting”. The sunlight can not bounce off the flat solar panel glass.

Further the tubes are very strong and can be replaced individually in minutes so you never have a down time or a complete loss of your solar systems power.
