In winter and spring, how big of the sun does it take to reach 50 degrees??? 20

It's not really good.

My family's is Tsinghua Sunshine's. In winter, even if the daytime temperature is below zero, as long as it is not cloudy, it can be forty or fifty degrees. In the summer, when the sun is full, it is boiling.

You may have forgotten the most important thing, is your solar water heater going in the right direction? It should be 10-15 degrees south-west, and if you don't align with the sun, of course it won't be hot.

I came quietly and went quietly, coming with nothing, and taking two points when I left, yes.

The vacuum tube of the solar water heater will not be frozen because it is vacuum, and the water tank will not be frozen. However, if the insulation of the pipeline is not thick enough or it is easy to freeze at the bend, over the wall and other parts, at this time, on the one hand, it is necessary to do a good job of heat preservation, and on the other hand, it is necessary to install an electric heat trace in the exposed part to prevent freezing. In addition, if solar energy is not used for a long time in winter, please close the water supply valve and drain the water in the water heater and the upper and lower pipes to prevent freezing and damaging the pipes.

In severe cold areas in winter, the outdoor pipeline may be frozen and blocked (you can't go up the water or know that there is water in the tank but can't put it down), if you have installed a heat tracing, please enable it to prevent the pipeline from freezing and clogging, freezing and cracking, but it needs to be closed in time after thawing; For users who do not have a heat tracing, it is best to use up the hot water that night, put on the water before the sun rises in the morning, or connect a basin under the sprinkler head or water outlet, open the mixing valve to make the water in the water heater tank slowly drip into the basin, and the flow of water in the pipe will prevent freezing and blocking (commonly known as drip antifreeze). If no anti-freezing measures have been taken, the pipeline can be automatically dredged after the temperature rises, but it is easy to freeze and crack the pipeline after multiple freezes.

There is a close relationship between the heating of the solar water heater and the light intensity, illumination time, solar wavelength, irradiation, wind speed, water capacity, etc. In winter, the sunlight is not strong, the light time is short, and the amount of solar irradiation that can be absorbed by the vacuum tube is greatly reduced, in order to obtain a relatively satisfactory water temperature and give full play to the maximum benefit of solar energy, the amount of water can be determined according to the capacity of the water tank and the weather forecast. In addition, even in severe winter, the vacuum tube must not be replenished immediately after there is no water in the air to prevent the tube from exploding.

Tips to get so much hot water.

In winter, when it is sunny, the solar water heater can be used normally. When the temperature is below -5, it is best to use the water in the water heater in small amounts and several times a day. In winter, there is more dust, less rain, and snow or dust covering the collector can reduce the heat collection efficiency.

If possible, it is advisable to wipe the vacuum tube to increase the heat collection efficiency. Special attention should be paid to water supply when using auxiliary electric heating, and the water volume in the water tank should not be less than 50% to prevent dry boiling without water. Be sure to turn off the power when bathing.

In windy weather, fill the solar energy with water to increase the wind resistance and load-bearing capacity of the water heater, and disconnect the power supply such as electric heating and instrumentation; The use of solar energy is prohibited during thunderstorms to ensure personal safety.

According to the weather conditions, you can decide the amount of water to get a more satisfactory water temperature. After taking a bath at night, if there is still half of the hot water in the tank that is nearly 50-70 degrees, in order to prevent excessive heat loss (the less water, the faster the heat loss), such as the next sunny day, full of water; On rainy days, then on 1 3 water. When taking a bath in the morning and evening, if the water in the solar water heater has been used up and the person has not been rinsed, you can use cold water for a few minutes, use the principle of cold water sinking and hot water floating, and push out the hot water in the vacuum tube, and then take a bath.

Linuoruite solar energy cannot be used at all in winter, not only is the water not hot, but it is also easy to freeze the tube.

Hello Wooder, dear! The reason may be 1The orange pie barrier of the control instrument will transmit the wrong signal or fail to transmit the signal, resulting in the inability to enter the water.

Just replace the meter. 2.The reason for the damage of the vacuum tube is mainly to water the solar water heater in the morning, because the temperature in the vacuum tube is already very high at this time, and if the cold water at this temperature is very low, it will **.

Therefore, when filling the solar water heater, be sure to choose to congratulate before sunrise or 3 hours after sunset. Damage to the vacuum tube will cause water to flow out of the broken pipe, and the water will go up and not be able to hold it. 3. Problems with upper and lower water pipes; If there are upper and lower water pipes that are not well insulated outdoors, it will cause the water pipes to freeze and the water will not be able to get on, so pay attention to opening the pipes for insulation.
