How to thaw the solar hot water pipeline?

Generally speaking, it takes 15-30 minutes to thaw after entering tropical areas. Turn on the hot water tap and start the tropical area at the same time. When hot water comes out, turn off the tap. The highest heating temperature in tropical areas is 70 degrees. The power is 25 watts per meter.

According to experience, when the temperature is below zero, some citizens can turn on the hot water tap of the solar water heater and let it drip slowly to keep the solar water flowing, which is also an effective way to prevent the solar pipeline from freezing.

In winter, if no one lives at home, it is necessary to drain the outdoor pipes and close the main water inlet valve. The handle of the mixing water valve should be placed in the warm water position and opened. Even in severe winter, the vacuum tube can't be replenished after being air-dried without water for more than 1 hour, so as to be explosion-proof.

Extended data:

Check whether the solar insulation pipe is in good condition, damaged, leaked and cracked before winter. Whether there is a water storage elbow in the outdoor pipeline.

Solar energy is generally equipped with heating and anti-freezing devices, and the public often unfreezes the pipes after freezing, which not only delays the use, but also damages the service life of solar energy.

The scientific method is to listen to the weather forecast when the temperature has been below 0℃ recently, and turn on the antifreeze device for preheating protection.

Don't worry about power consumption, because in the process of use, the power of the electric heating belt will decrease with the increase of temperature, and the power consumption is extremely small. Especially in the cold north, when the temperature is always below zero, the heating and anti-freezing device will be turned on.

In other areas, if the temperature is low at night, antifreeze can be turned on at night and turned off during the day.

When taking a bath, you should also pay attention to unplugging and cutting off the power supply to prevent accidents in which the heat balance is out of control. If it is rainy and snowy the next day, you can add half a box of water as needed.

Listen to the weather forecast, the temperature should not be too low 5℃-7℃. After entering the water at night, if there is a water tank and hot water, the solar water heater should be filled with water immediately to reduce the water temperature and heat loss at night. If the temperature is low, water it the next morning to help the water heater outlet pipe to prevent freezing.

If it rains or snows the next day, use half or half of the water tank as needed; If you use too much water, consider turning on the electric heater of the solar water heater.
