You can take a bath when the temperature is above 35 degrees.
Solar energy refers to the energy of thermal radiation from the sun (see the three modes of propagation of thermal energy: radiation). Its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has relied primarily on thermal radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as crafting. salt and dry the salted fish. With the decline of fossil fuels, solar energy has become a significant part of human energy consumption and continues to grow. There are two ways to use solar energy:photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
Advantages
(1) Universal: The sun shines all over the earth and there are no geographical restrictions, whether on land or sea, on mountains or the islands. and can be directly developed and used. It is easy to collect and requires no mining or transportation.
(2) Harmless: The development and use of solar energy will not pollute the environment. It is one of the cleanest sources of energy, which is extremely valuable today as environmental pollution becomes more and more serious.
(3) Huge: The energy of solar radiation that reaches the Earth's surface each year is approximately 130000 billion tons of coal, and its total quantity constitutes the largest energy that can be developed in the world today.
Will the water temperature in the solar water heater be too high to burn out the machine?
It depends on the water temperature in the water tank. If it is cold water, it will take about 3 days to turn on the electricity to heat it. It takes more than an hour to heat the water to 75 degrees and the water heater will automatically stop heating. the water heater. When the heating light goes out, you can take a shower.
If you take a bath in summer, you can take a bath after turning on the power for about 20 minutes. The suitable temperature for human body bathing is generally around 42 degrees, but in winter it is better. have a higher temperature. A 50 liter water tank is usually enough for one person to take a bath after que the water heater automatically stops heating.
Detailed information:
The vast majority of solar water heater instructions include a “not for consumption” warning.
Although the water entering the water heater is clean tap water, the materials used to make the water heater and its supporting components (such as metal pipes, etc.) ) can often contain harmful substances such as lead, cadmium. , manganese and arsenic poison. In addition, the temperature of the water heated by solar water heaters is generally between 40°C and 70°C, which is conducive to the reproduction of bacteria and viruses.
In addition, whether it is a solar water heater or an electric water heater, there is a water storage tank. Unused water may be stored in the tank over time, causing the discharge ofe the previously heated water. pollute.
SunThe water temperature in the solar water heater can reach a maximum of 100°C. In the early stages of the design of the solar water heater, the problem of combustion and aging of components was not taken into account. Burnout.
However, it is recommended not to maintain high temperatures permanently. If the temperature remains high for too long, it will accelerate the aging of the water tank coating and various accessories. Therefore, it is recommended that when the solar water heater is not used for a long time, the automatic water supply function should be turned off or the water in the solar water heater can be drained.
