The main reasons for the low solar energy flow are the following three aspects:
First, ordinary solar water heaters are non-pressure products, and the pressure of hot water outlet depends mainly on the size of the drop. If the distance between the solar water outlet and the place of use is small, the hot water flow will be small and the pressure will be low when used. Especially for users who live on the top floor, they will feel it clearly when using. once again. The solution is to appropriately increase the height of the solar power to increase the height difference, or use larger diameter upper and lower water pipes.
The second is that the pipes are long and have bends, which means the water pipes are bigger and bigger. hinders the flow of hot water. The solution is to reorganizethe pipeline;
The third is that there are blockages at the water inlet and outlet or the upper and lower water pipes. The solution is to have service personnel come to the door. for inspection.
The water flow of the solar water heater is too low
The vertical drop between the solar water tank and the bathroom shower head is too small ; too many turns of pipe and thin pipes will do this. this will also affect the hot water pressure; if the horizontal pipe is too long, which will also consume part of the water pressure, it is recommended to connect a booster pump in parallel to the pipe only for bathing, this will solve the problem; The water is most likely caused by a blocked faucet hose or filter; Ordinary solar water heaters cannot bear the pressure, the size of the hot water outlet pressure mainly dependsmainly the size of the fall. If the distance between the solar water outlet and the place of use is small, the hot water flow will seem low when used. The pressure is less, especially for those who live on the top floor in the morning, they will obviously feel it when using it again. Appropriately increase the height of solar power to increase the height difference, or use upper and lower water pipes with thicker diameters; the pipes are long and have bends, which interfere with the flow of hot water, and rearrange the pipes if there are blockages; at the water inlet and outlet or upper and lower water pipes, you can ask professional after-sales service personnel to come to your house for maintenance.
1. The water outlet pipe is blocked
The water flow of the solar water heater is low As we just said, it isthe most intuitive judgment. 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 phenomenon will 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 from being blocked. During the process of heating the water in the water storage tank, the pressuren volume expansion is too great 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 become soft if not fixed well, it will sag, bend or collapse. This situation is particularly evident the higher the water temperature. Equivalent to If the pipe diameter is reduced, it will also cause low water flow.

Solution
1. First check the height difference between the solar water heater andthe 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 this has some relationship with the type of shower head we use, some pressure shower heads may be more comfortable.
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, my suggestion is to check the water outlet first to see if there is a blockage. If blocked, cleanz 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 pipes are bent due to the gravity of the water or the 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 theThe 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 it. 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.
