According to the experience of some citizens, when the temperature is below zero, you can turn on the hot water tap of the solar water heater to make it drip slowly and keep the solar water flowing smoothly, which is also an effective method to prevent the solar pipeline from freezing.
In winter, if the house is unoccupied, the water in the outdoor pipeline should be discharged, the main water inlet valve should be closed, and the handle of the water mixing valve should be placed in the warm water position to open. Even in severe winter, if the vacuum tube is exposed to air for more than 1 hour without water, it can't be replenished to prevent the tube from bursting.
Extended data:
Before winter, check whether the solar insulation pipe is well insulated and whether there is any phenomenon such as disconnection, leakage and cracking. Whether there is a water storage elbow in the outdoor pipeline. ,
Solar energy is generally equipped with a heating and anti-freezing device, and citizens often use it to defrost after freezing in the pipeline, 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 and turn on the anti-freezing device for preheating protection when the temperature has been below 0℃ recently.
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 the smallest. Especially in the cold areas in the 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, the anti-freezing device 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 the heat balance from getting out of control and accidents. If it is rainy and snowy the next day, you can need half a box of water as needed.
Listen to the weather forecast, the temperature should not be too low (5℃-7℃). After using water at night, such as water tank and hot water, water should be injected into the solar water heater immediately to reduce the water temperature in the water tank and the 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, you can use half or half of the boxed water according to actual needs; If you use too much water, consider starting an electric heater in your solar water heater. ,
