Talk about my own feelings: 1. Solar power is always great in summer because you can have hot water almost every day. In winter there are many rainy days and low temperatures. The sun only shines during the day and hot baths can be taken at night.
2. The solar bath requires a large difference in soil (the location of the solar installation is different from where you live), so that the water flow is relatively large and comfortable.
3. It is best to bring an electric heater so that you can take a hot bath every day in winter.
4. My house then had rapid electric heating installed, which alleviated the winter bathing problem.
Can I use solar energy to take a shower on a rainy day?
Solar water heaterYou don't can't take a shower with water that hasn't been used in a long timegtime.
If it is not necessary for a long time, we can first drain all the water from the water heater and turn off the power. If it is not drained it will be in a tank. high temperature and high pressure state for a long time, which will produce a lot of gas and water pressure, also cause certain damage to the water tank; then disassemble the heat collecting tube and cover the vacuum tube with a blanket or quilt to avoid The heat collecting tube and vacuum tube are not burned by the sun during long-term exposure.
Choose a water heater
1. First of all, if you want to be able to take a bath with hot water at any time, then the editor recommends choosing an electric water heater. or a gas water heater. It is better not to choose a solar water heater, because the solar water heater Water is heated by the heat of the sun. By weathers cold, especially in winter, the warmth of the sun is not enough, the water cannot be heated in time, and bathing will become inconvenient.
2. We should also choose a water heater with excellent heating performance and quality. Sometimes we will buy cheap but poor quality water heaters, and various problems will often arise after using them for a while. Therefore, we should choose a well-known water heater at the beginning to ensure its quality. will be guaranteed, which is safer to use.
On rainy daysyou can use solar energy to take a bath, but it is still not recommended.
During thunderstorms, it is recommended not to use electrical appliances or solar water heaters for bathing, as you are concerned that lightning protection facilities may not be perfect and can cause lightning. CepenHowever, current transmission lines, including many household appliances or equipment, have good lightning protection designs, so there is no problem in normal use.
Of course, if you can use it, it's good to be patient. If the lightning protection installations prove to be defective, an accident may occur.
Since the birth of life on earth, it has mainly relied on the energy of thermal radiation provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method. to prepare food, such as making salt and drying salted fish.
Working principle:
Sunlight passes through the first glass layer of the heat-absorbing tube and shines on the black heat-absorbing layer of the second. glass layer.The heat absorption of the enesolar energy, due to the vacuum insulation between the two layers of glass, the heat transfer will be greatly reduced (radiant heat transfer still exists, but there is no heat conduction or heat convection), and most of the heat cannot be transferred to the glass The water inside the tube heats the water inside the glass tube.
The heated water becomes lighter and flows upward along the heating surface of the glass tube into the insulated water storage bucket. The relatively low temperature water in the bucket enters the glass tube along the backlit surface of the glass. tube for replenishment. In this continuous cycle, heat conservation. The water in the water storage barrel is continuously heated to achieve the hot water target.
