The solar water flows by itself and the pressure is too low. If the hot water flow is low, it is a problem of lack of solar energy. First, add a booster pump and use a small booster nozzle. . Better. If it is more than two years old, first check if it is caused by scale in the shower head (nozzle). You can unscrew the shower head and see if the water volume is still low. This may be due to excess scale in the shower head. water mixer. Another reason is that there is scale on the water outlet of the water storage barrel.
Solutions to the problem of too low water flow from the solar water heater:
1. Replace the pipes and increase the diameter of the pipes.
2. Add a miniature booster pump to the water outlet of the solar water heater.
3. There is now a supercharged shower that does not have electrical supercharging. As long as the cold water flows normally, it can flush hot water after use, there will be at least 3 times. more hot water than before use. It can also prevent hot and cold, anti-scalding, anti-scaling, thermostatic valve is omitted.
4. It would be better to add a booster pump and use a small booster nozzle.
1. The water outlet pipe is blocked.
The water flow of the solar water heater is low. As we just said, it's the most intuitive. judgement. This is because the water in the solar water heater is hard and scale is produced during the heating process, which adheres to the inner wall of the outlet pipe and valve.
If the water outlet pipe is partially blocked due to shower heads and other places, the diameter of the pipe will become smaller and the water outlet volume will become smaller. This situation has some persistence and water. the flow will decrease day by day. This phenomenonwill occur in many solar water heaters with poor water quality for 1-2 years of use.
2. The air outlet of the solar water heater is blocked.
On the top or side of the water storage tank of the solar water heater, there is usually an air outlet to pressure. relief and exhaust to prevent solar energy During the process of heating water in the water storage tank, the volume expansion pressure is too large and the water tank bursts. Although it is called air outlet, it is used for air inlet when we use water.
3. The outlet pipe is bent.
Some friends' solar outlet pipes are not strong enough. When the water temperature is not high, however, there is no problem with the water flow. , once the water temperature is too high, or when the outside temperature is high, the pipe will becomeIf it is not properly secured, it will sag, bend or collapse. This situation becomes all the more obvious as the water temperature is high. This equates to a reduction in pipe diameter, which will also result in low water flow.

Solution
1. First check the height difference between the solar water heater and the water point
There is actually no verification on this. of course where the solar energy is installed. Understand, what I mean here is that the height difference between the solar water heater and our water point must be at least two meters, so that we can feel that the pressure of the water is sufficient. Of course, it is different from what we use. The type of shower head you use has a certain relationship. Some supercharged shower heads may be more comfortablebles.
2. Then check if the air outlet is blocked.
As we said above, a blocked air outlet not only affects the water flow, but also affects the amount of water. water we provide. In severe cases, this can also lead to deformation of the water tank. So if we find that the solar water production is low, I suggest you first check the water outlet to see if there is any blockage. If blocked, clean and purge immediately.
If it is the pipe outlet type, it is recommended to replace it with one made of harder material. Also remember not to cover the air outlet in any way, including using a breathable fabric to cover it. This can easily clog it and affect water flow.
3. Check again whether the pipes are bent or not.
Especially when we use hot water, we can check if the pipesaux are bent due to the gravity of the water or pipe. If the hose is kinked, I recommend replacing it immediately with a regular hot water hose and securing it properly.
It is worth noting here that if you use PPR pipes, you must use PPR for hot water pipes. My suggestion is to use aluminum-plastic composite pipes, which have better strength and are less likely to kink.
4. Finally, check if the waterway is blocked.
After eliminating the above three reasons, let's check our waterway system. The first thing to do is to look at the faucets and. shower heads. These places are most likely to be clogged. You can confirm this by removing them and checking the water volume. If cleaning is of no value, it is recommended to replace them directly.
The second is the water pipe. There is no good way to clean itr. You can use citric acid, pour it into the pipe from the top, soak it for a while, then rinse it. . Generally there will be no problems. The main reason is tartar blockage. There is also a filter, if installed. It's best to check and clean this first.
