Description :

1. Using a high efficiency heat pipe and heat transfer fin design to conduct the heat from within the all glass vacuum tube up to the header.
2. Due to the vacuum between the two glass tubes, conductive and convective heat loss are eliminated.
3. The tube is 100% glass, the problem with loss of vacuum due to a broken seal is greatly minimized, therefore, these tubes perform very well in overcast conditions as well as low temperatures.
4. The evacuated heat pipes used in Lotusino solar collectors have a boiling point of only 30 celsius degree which leads to its rapid heat transfer and excellent low temperature performance.
5. Due to the cylindrical absorber area, which passively tracks the sun throughout the day, lotusino collector have a stable solar conversion all day.
6. Suitable for mains pressure water.
7. Easy plug in installation.
8. The perfect solar collector for domestic solar water heater systems, also ideal for commercial solar water heating applications.
