Why is it that no one installs solar water heaters that were popular in rural areas in the past?

1. There are restrictions on the use of solar water heaters, and there is no hot water in cold weather in winter

Seeing this problem, many friends in rural areas in the south may begin to object. Because the climate in the south is relatively warm in winter, there is no particularly cold weather. But for the vast rural areas north of the Yangtze River, especially north of the Huaihe River, water drops turn into ice during the cold winters. In winter, the water supply pipes of solar water heaters are completely frozen, and it is difficult to thaw until spring. There is no hot water at all in winter. Like our rural areas in the Dabie Mountains, during the Chinese New Year, you can only use firewood to boil water for bathing. Occasionally, when the weather is particularly good and it is sunny for many consecutive days, it is possible to provide hot water using solar energy. However, this intermittent and intermittent situation has indeed interfered with the lives of farmers. Many people find it very troublesome and useful, and it is better not to use it.

2. Solar water heaters are easy to break, and repairs are troublesome and expensive.

When solar water heaters were promoted in rural areas in the past, many water heaters were of unknown brands and had no products. Many farmers do not know the real situation, are deceived, and are greedy for cheap, so they buy and install them. As a result, within two or three years of use, we found that the water heater often broke down. For example, a no-name solar water heater installed in my home before. After three years, several pipes became black and broken, and it could not heat at all. In the words of my father, if you put a basin of hot water outside to bask in the sun for a day in the summer, the temperature of the water will be higher than that of the water in the solar system. However, for such miscellaneous brands, they are often replaced by one shot at a time. If you want to find after-sales maintenance personnel, you can't find them. If you want to repair it yourself, there are not many dedicated maintenance personnel in small rural towns. Even if there are, the cost of labor and materials is very high, and many people think it is not cost-effective.

3. There is no running water installed in rural areas, and it is very troublesome to fill the water heater.

In most rural areas of our country, running water is not installed, especially in remote mountainous areas. The current water use model is either to dig well water or to collect water from mountain springs. For example, in our hometown, we connect the water pipe from a spring on the mountainside and use the natural drop to deliver the water to our homes. However, there are often sand and leaves in mountain spring water. Even if it is filtered with a filter, some will still enter the water pipes.

Especially during flash floods, the water quality is very poor and there is a lot of sediment, which is particularly easy to block solar water pipes. There is another difficulty in our local area, because the houses in the village are built according to the mountain topography and are scattered up and down. Therefore, as long as someone lower than our house releases water, the water pressure in our house is not enough and cannot be delivered to the second floor platform. The solar water heater is on. My dad often has to get up in the middle of the night to get water, otherwise dry burning will easily occur.
