Heat Pipe Solar Water Heaters
1) The tube structure is between all-glass evacuated tube and metal-glass evacuated tube with heat pipes
2) Suitable for frigid zones because there is no water in the tube
3) Designed for pressure system
4) Heat pipe material: TP2 copper
5) The heat collecting part is a vacuum glass tube that lowers heat loss
6) Stable solar conversion throughout the day, with the round shaped tube allowing solar penetration from all angles.
