A few years ago, no company produced 48-tube solar water heaters. The main reason was the problem with the coating and insulation of the tank.
The possible situation is that the secondary foaming of the insulating layer compresses the water tank liner, causing the water tank liner to collapse.
In addition, the exhaust port may be blocked. When the hot water is discharged, there is negative pressure in the water tank, which will also deflate the water tank.
Apart from this, the other possibilities are relatively weak. Not listed here. If it is the problem above, it is a water tank quality problem. If it is the following problem, it is a “natural disaster”. Generally does not affect the use.
How many people can take bath with 42 tube solar water heater?
I think it is better to buyetter large items at home directly from specialized stores or companies. Product quality. Insurance on Taobao is a problem.
First question: The brands you mentioned are not mainstream products, compared with Huangming (waterfall type), Tsinghua Sunshine
(waterfall type)
There is definitely a big difference between Samp (pressure-bearing type) and Soller Sunshine (pressure-bearing type).
The second question: the more pipes, the larger the capacity of the water tank will be. Smaller manufacturers generally don't make large capacities.
The third question: The installation of solar products is more important than the quality of the product itself. Three points for the product and seven points for the installation. The places where problems occur most often are piping components, which are not easy to install or use.
LThe fourth problem. After-sales service is very important. Solar energy without repair or maintenance is like an orphan. I don't know how to fix it myself. This industry is not very mature and it is difficult to find maintenance personnel.
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 and 45 degrees Celsius. Different brands of solar water heaters have very different ratios of vacuum tubes and water tankss, as well as the heat collection efficiency of the vacuum tubes and the rate of increase in water temperature.
