Generally speaking, a 42-tube solar water heater can bathe 7 to 10 people. The number of people who can take a bath is mainly related to the capacity of the solar water tank and the water temperature. The water tank has a large capacity and can provide a large amount of hot water; the solar water tank has high water temperature and can provide enough hot water with more cold water. Under normal circumstances, the average daily hot water consumption per person in a household is around 50 liters at 45 degrees Celsius. Different brands of solar water heaters have very different ratios of vacuum tubes and water tanks, as well as the heat collection efficiency of the vacuum tubes and the rate of water temperature rise.
Will it be easy to break if there are too many solar tubes?
The less water shared by the tubes, the hotter the solar panel will bequickly and the stronger its heat collection will be. performance will be. Normally, a 1.8 meter thick pipe should carry 8-9 liters of water, and a 1.5 meter long thin pipe should carry around 6-7 liters of water. In fact, the less water a single pipe carries, the better.
The more parts an object has, the worse the reliability. As long as the goal can be achieved, a product is constructed with an appropriate number of parts.
If you use 18 tubes, this will be appropriate. There is no need to use more tubes.
For example, if the chance of failure of a tube is one in ten thousand and you use 10 tubes, then you don't know when the tubes will be broken. If your pipes are broken, but you have used 10,000 of them, then one of your pipes must be broken. This means that the more you use, the higher the risk of failure. .
For solar water heaters, not so much.It is better to increase the volume of the water tank than to increase the number of pipes. Because on sunny days, especially in summer, it is common to have water. The temperature can reach over 80 degrees. However, if the water temperature is too high, it will harm the water tank. Insulating materials and pipe plastic will age more quickly at high temperatures, but real water is only used for showering. should be about 43 degrees.
Therefore, increasing the volume of the water tank can make full use of the existing pipes and increase the water storage capacity. Hot water can be extended until the third and fourth days. and lowering the temperature increases the life of the system, which is a desirable direction.
