Brief introduction: Cobest solar vacuum tube is a high efficiency and superconducting heat tube. Its thermal efficiency reaches above 95%, which is 10000 times than copper. This tube has a strong ability to resist cold, resist water scale and hold water. Occasionally damage can not influence the total running. The water tank using Cobest solar vacuum tube can increase about 10% hot water energy than common solar vacuum tube water tank.
