Description

Technical Field

In winter, there is heating supply indoors, and the walls of the house are relatively hot. The upper and lower water pipes of ordinary solar water heaters are not prone to freezing before they are out of the wall. However, the outdoor water tank is very easy to freeze in cold weather because the insulation performance of the outer insulation layer is limited and the water in the water tank is in a stagnant state for a long time.

The device has a simple structure, and the upper and lower water tanks, solar vacuum tubes, main pipes, and branch pipes form a closed circulation pipeline, which can effectively prevent the water inside the outdoor pipeline from freezing by forming a microcirculation.
