Which is the best solar water heater tube?

Answer:

The color of the vacuum heat collecting tube is mainly blue and black, and the overall chromatic aberration is small. But black does not indicate the quality of vacuum heat collecting tube is good, because some manufacturers in order to cover up variegated, often made of pure black film. In fact, there is a certain error in the color of the vacuum heat collecting tube, which is unavoidable, and does not affect the heat collecting efficiency of the vacuum heat collecting tube.
The surface of the vacuum heat collecting tube is smooth and clean, the pipe body has no spots, no air lines, no scratches and no film forming. (this phenomenon will affect the collection efficiency and beauty).
The vacuum heat collecting tube has the mirror surface complete, bright and clean, without blackening and blackening.
There are three kinds of vacuum heat collecting tubes: high temperature pipe, high efficiency pipe and high cold pipe. High temperature pipe coating than ordinary length (from the nozzle is about 1cm), the tube of high temperature resistance, anti damping performance is particularly strong, the film on the 400 DEG C high temperature air drying condition, not aging, not falling, not color. The high efficiency pipe film is about 2.5cm apart from the pipe mouth. The tube is ultra high absorption, less heat loss, fast heating up and high thermal efficiency. The high temperature pipe has the advantages of high efficiency, high heat efficiency and fast heating, less heat loss, and hot water as usual under the condition of 30 DEG C. Consumers can choose different vacuum heat collecting tubes according to different areas.
