1.higher heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorb coating and perfect combination with high vacuum tube heat preservation

2.wide applicable range:as the heat pipe has less heat capacity,it canbe started quickly even under couldy fine day and collect heat effectively.it can work normally even-30 below degree.as no water in the vacuum tube,it can effectively prevent lowing of heat efficiency due to frost cracking or scalling

3.each individual tube can work independently,and the whole machine can still work if individual tube is damaged.the service life of the heat pipe canbe longer than 15years.

4.the unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube.
