Feature:

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 (86 Fahrenheit 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 (up to 8 bar/116psi);

7.       Easy plug-in installation;
