How to solve the problem of small hot water production from solar water heaters

First of all, we need to check the water tank of the solar water heater. If there is too little water in the water tank, the solar water production will be low. In this case, we need to add water to the solar water heater.

Also, if the solar water heater is installed in a place exposed to direct sunlight, the solar water production will also decrease. If it is due to this reason, it will cause a decrease in solar water production. It is best to contact the solar water heater directly. Our after-sales technicians will come to help you with reinstallation, otherwise it will affect our normal use in the future.

Precautions for using solar water heaters

1 The use of solar water heaters requires regular maintenance and it is best to call to professional maintenance personnel. maintain.

2. It should be noted that after one useLong-term use of solar water heaters, the problem of scale accumulation in water pipes will also occur. Once too much scale builds up on the inner tank, it will also occur directly. affect the water production of the solar water heater.

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 phenomenon will occur in many solar water heaters withc poor quality water for 1 to 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 become soft if it is not fixed well, it will sag, pwill bind 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.

Detailed information:

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 solar energy is installed. Please understand, what I mean here is that solar water heaters generally need to be at least twice away from our water points. It is estimated that the water pressure is sufficient only when the height difference is greater than 1 meter. Of course, this has something to do with the type of shower we use. Some supercharged showers 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 we supply. 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 pipes are bent due to the gravity of the water or the pipe. If youyau is kinked, I recommend immediately replacing it 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 it. You can use citric acid, pour it into the pipefrom above, 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.
