What is the reason why solar water heaters always burst water pipes?

Causes of bursting of hot water pipes of solar water heaters;

1, after the solar water tank is waterless, the vacuum tube temperature is high during the day. If water is added at this time, it is easy to blow up the pipe due to excessive temperature difference, which is the most likely.

2. When there is less water in the vacuum tube, due to the high temperature, the steam after boiling water will release a lot of heat when it meets cold air, and it will condense into water at the nozzle, and the vacuum tube will overheat, expand and burst locally, but it is less likely.

3. The vacuum tube can't keep warm due to air leakage, which causes the water in the tube to freeze without light, and the vacuum tube will crack.

Usage and precautions:

1, full tank of water is well insulated, and half tank of water loses temperature fastest, so try to keep the water tank full.

2. Grasp the water supply time, try to supply water at night or before the sun comes out in the morning, and read the instructions carefully to master the functions of the instrument.

3. When the temperature is lower than 0℃, it is best to use the water in the water heater several times a day, and rely on the water temperature to raise the pipeline temperature.

4. Pay attention to the weather forecast. When the temperature is very low, fill the water tank with hot water at night, then put a basin under the nozzle or faucet, loosen the hot water valve slightly and let it drip slowly to keep the water flowing in the pipeline to avoid freezing and blocking the pipeline.
