Heat pipe solar collector, vacuum tube type solar collector

Could operate in very cold days, even under **0℃ ambient temperature. 

Fast system starting and rapid thermal conductivity in winter time. 

Season independent operation thanks to the anti-freezing heat transfer medium. 

Larger heat transfer end and wider copper pipe for faster heat transfer and higher efficiency. 

European Solar Keymark certified, with satisfactory annual energy yield. 

Could work smoothly with high efficiency in winter days, even under **0℃. Both the φ*4 andφ*4 heat transfer end are available.
