Each year in March and April is the peak period of decoration since the spring, in addition to a variety of building materials, home appliances is also a concentrator to buy, in the area, many families use solar water heaters, environmental protection and energy saving but also safe, but many friends also encountered To the various problems of solar water heaters, today I will introduce them to you: 
Under normal circumstances, each person takes 20-40kg of hot water for one bath, and each vacuum tube can heat 6.5kg of water. Based on the family population and the customary bath water consumption, the required water heater capacity can be estimated.
To use solar water heaters in areas without tap water, it is generally possible to use the water from the pumps and add an auxiliary tank to the same height as the solar water heater to store cold water so that it can be used to bathe cold water.
It may be because the vent hole is blocked. When the water enters or discharges, the internal air cannot be discharged or replenished instantaneously, resulting in a pressure difference between the inside and the outside, resulting in breaking or squeezing the water tank.
The relationship between the size of the water tank and the number of vacuum tubes?
General water heater design is designed according to the required hot water bath temperature, general solar water heater design water temperature range is 400C ~ 900C, roughly each tube heating water 6.5kg.
Vacuum tube solar water heaters should pay attention to what issues?
As the vacuum tube is in the air, the temperature in the tube can reach about 2500C, so waterless or first water in the tank must be performed before sunrise or half an hour after the sun goes down.
How to distinguish the advantages and disadvantages of solar water heaters?
Solar water heaters are a type of solar thermal utilization. The entire water heater includes a heat collection section, a heat storage section, and a bracket section. The main reason for distinguishing the heat collection part is the absorption rate and the divergence rate of the heat collection element, which is related to the material and the manufacturing process.
The heat storage element is the warehouse of the water heater. It has two quality guarantees: one is leakage, and the other is insulation. Liner welding is very important, the strength of welding and whether the material is anti-corrosion is the key to the quality of the interior of the tank. In addition, the insulation material determines the insulation performance. In cold areas, thick insulation must be used.
The bracket supports the main part of the operation to ensure the correct position of the heat collecting element. It needs to have the same life span as the other components of the mainframe. This requires good strength and corrosion resistance, and it can be judged by its visual inspection. Material, thickness, surface treatment.
