1. Natural defrosting.
When the temperature is high and the sun is shining, let it melt naturally.
For solar water heaters that have been frozen, do not forcibly flush the solar vacuum tubes with hot water. Try not to rinse naturally at the peak of the sun. the solar tube with hot water, otherwise it will damage the vacuum tube.

Each solar hot water pipe is equipped with a heating tape, and when the heating tape is turned on, the solar energy can thaw.
Detailed information:
Energy use and maintenance precautions solar in winter: < /p>< p>1. Pay attention to the weather forecast in winter to get a more satisfactory water temperature. If the sunlight is not strong that day, you can add half a tank ofwater, or more than half a tank of water. , according to actual needs. If the weather is good the next day, the water tank of the solar water heater can be filled. If the temperature is low, it is better to refill the water tomorrow morning, which will avoid pipes at the solar water outlet. heating of the gel.
2. Perform a complete inspection. Check for disconnected, leaking, cracked, etc. pipes. and use good quality insulation materials or anti-freeze devices for protection. If there is a heating tape during installation, the pipe heating tape will automatically heat the pipe according to the outside temperature. When the temperature reaches a certain temperature, the heating tape will automatically cut off the power, which can effectively protect the pipeline and prevent. frozen.
