How is the heat transferred from the tube to the water?

The pressurized red copper heat pipe boils liquid at low temperatures (75-80F), carrying heat to the top where it is transferred to water or heat transfer fluid flowing around the pipe.

What are the installation options for this collector?

It can be easily installed on flat roofs, inclined roofs, walls, or the ground, allowing for complete integration with buildings.

What is the working pressure of the collector?

The working pressure is 6 bar, with a testing pressure of 12 bar, ensuring safe and stable operation.

Product Q&A

Q:What is the warranty period for this solar collector?

We provide a 5-year warranty for this product, along with available after-sales service.

Q:How does the vacuum tube technology improve efficiency?

The double-wall borosilicate glass creates a vacuum layer that acts as superior insulation, significantly reducing heat loss and improving heating efficiency compared to flat panels.

Q:Is this solar collector suitable for freezing climates?

Yes, it has strong freezing resistance because there is no water inside the solar evacuated tubes, preventing damage from freezing temperatures.

Q:What materials are used for the frame and pipes?

The frame is made of 2.0mm thick aluminum alloy, and the heat pipe and header pipe are made of red copper with 0.6mm and 1.0mm thickness respectively.

Q:What certifications does this product have?

The product is certified with ISO and CE standards, ensuring it meets international quality and safety requirements.
