How to solve the unstable pressure of hot and cold water in the solar water heater at home?

The instability of the cold and hot water pressure of the solar water heater is generally due to the change of cold water pressure, and the general hot water is natural pressure (not much change), so it can only be solved by changing the cold water pressure.

There is also the possibility of changing the ordinary mixing faucet to a constant temperature mixing faucet, which will also work very well, if the toilet can be equipped with a water tank on the top, you can also adjust the cold water pressure through the automatic water tank.

Only one valve can be added on both sides of the mixing water valve to assist in controlling hot and cold water, and the water temperature of solar energy cannot be fixed, which is really difficult to adjust, and can only play an auxiliary role.

The best thing to do is to install a thermostatic mixing valve, which can solve the problem of hot and cold water temperature.

Nowadays, many people use air source heat pumps to make hot water, and the hot water used in my dormitory is quite stable now, but if you turn on the cold faucet, the hot water temperature will be relatively reduced. Turn off the cold water, the temperature of the hot water rises, I don't know if the solar energy is yes yes yes this problem.

The reason why you adjust too fast, you can adjust it slowly and steadily.

This problem is best to replace the mixing valve with an automatic thermostatic valve, Huayang pressure solar energy completely solves the problem of drizzle or cold and heat.

1. Add a booster pump outside the water tank: In order to increase the pressure of hot water, a hot water booster pump can be added at the solar hot water pipe on the roof, which can solve the problem of hot water pressure.

2. Replace the thermostatic mixing valve: The principle of the thermostatic mixing valve is to use the characteristics of the temperature sensing element of the mixing outlet to promote the valve core in the valve body to move, block or open the water inlet of cold and hot water. When the temperature adjustment knob is set to a certain temperature, no matter how the temperature and pressure of the cold and hot water inlet change, the proportion of cold and hot water entering the outlet will also change, so that the outlet temperature remains constant.

3. Adjust the water pressure of tap water: reduce the main valve of indoor tap water to the point that it does not affect the daily use of cold water, so as to reduce the water pressure of cold water, so that the water pressure of cold and hot water can reach a balance, and the hot water can also be adjusted through the mixing valve.

Precautions for the use of solar electric water heaters

1. When the weather is extremely hot and the water temperature is extremely high, the water supply valve must be used to limit the pressure and add water. It is strictly forbidden to add water after the water is exhausted. Fortunately, the water should be supplied before sunrise in the morning or two days after the sun sets in the evening, so as to ensure the service life of the water heater.

2. Each water heater has an exhaust hole, and the number of water outflows is normal when the water is full, and it will stop after closing the water valve. (This does not happen with water heaters with water temperature level indicators installed).

3. Electric heating: The power of electric heating is 1500W, if it is used in cloudy days or when the water temperature is not enough in winter, do not plug in for a long time. The power must be turned off when bathing. When plugged in, if the leakage protection plug is red when it is on, it proves that it is heating, and when the green light is on, it means that the water temperature has reached 65.

4. When the temperature is not too low (7 -5), after the water is used up at night, there is still some hot water (water in the vacuum tube) in the water heater, which should be filled with water immediately, reduce the internal water temperature of the water heater, reduce the heat loss of the night, and make full use of the heat energy.

1. If the solar water heater is a falling water type, a booster pump can be installed, and when the water is on, the booster pump can be turned on to increase the water pressure.

2. The ordinary water storage tank relies on the height difference to achieve the hot water pressure, and the water level difference on the top floor is small, so the hot water pressure must be small, and the pressure-bearing solar energy can be replaced to ensure the stability of the hot water output.

3. Install a microcomputer controller for solar water heaters, set up a program, and the water pressure will be automatically filled with water when it is enough.

4. It is recommended to install an automatic controller at the end of the overflow pipe and the water supply, when there is water flowing out of the overflow pipe, there is a pressure or signal, so as to close the water valve.

5. Use the automatic water float valve, install the valve at the bottom of the water tank, connect with the water supply pipeline, when the water tank falls into the water, close the water outlet by the pull of the float, so as to realize unattended, so that the indoor water valve is opened before going to bed, and the water tank will be automatically filled when the water pressure is sufficient in the middle of the night.

6. The main valve of indoor tap water can be adjusted to a minimum level that does not affect the daily use of cold water, so as to reduce the water pressure of cold water, so that the water pressure of cold and hot water will reach a balance.

My solution was to add a booster pump that would automatically adjust the output pressure based on the user's set pressure.

Add it to the situation that the solar water heater is especially suitable for the situation where the water is located in a high place and the water point is at a high place.

Hope my reply can help you, thank you!

The easiest way to add a booster pump to the outlet pipe is to add a booster pump to the outlet pressure of a solar water heater, but remember to buy a hot water type. In addition, if possible, the height of the water heater can be raised, so that the pressure will be higher.

Summary. Hello, dear, the solar water heater has a large cold water and a small hot water because the flow of cold water is large, and the flow of hot water is small. The cold water pressure is high, and the hot water is not pressurized, because there is a blockage in the hot water pipeline, which causes the hot water to flow normally, resulting in insufficient hot water pressure.

The specific situation needs to be analyzed and solved according to your actual situation. It is recommended that you first check whether the hot water pipeline is unblocked and check whether the hot water faucet is working properly. If there is a problem, you can replace the hot water tap or clean the hot water line.

If the problem persists, it is recommended that you contact the after-sales service personnel of the solar water heater for repair or replacement.

How to return to the cold water pressure of the solar water heater when the cold water is large and the hot water is small, and the hot water is not pressurized?

How to solve the problem of solar hot water without pressure.

Hello dear, the solar water heater has no pressure due to insufficient pressure inside the tank. To solve this problem, you can use the following methods:1

Clean the water tank: The impurities inside the water tank, burning branches, and dirt will affect the airtightness and normal pressure of the water tank. Cleaning the tank regularly can keep the tank airtight and normal pressure.

2.Install a water refill valve: Install a refill valve at the bottom of the water tank, which can replenish the pressure inside the water tank and make the water tank work normally.

3.Replace the seal: If the seal of the tank is aged or damaged, it will cause insufficient pressure inside the tank.

Replacing the seal can solve this problem. 4.Retrofitting of booster pumps:

If the above methods do not solve the problem, you can add a booster pump to increase the pressure inside the tank. However, it should be noted that the power and noise of the booster pump are relatively large, so it is necessary to pay attention to the installation location and safety of use.

What should I do if the water output of solar hot water is small, the tap water pressure is high, and the mixing valve is not well adjusted, and the water temperature is too high or too cold?

1. Check whether the outlet valve of the solar water heater is open, and confirm whether the outlet valve can be opened normally; 2. Check whether the water flow of the solar water heater is normal, if the water flow is too small, you can check whether the water inlet pipe of the solar water heater is blocked; 3. Check whether the mixing valve of the solar water heater can be adjusted normally, if the mixing valve is not adjusted well, the mixing valve can be replaced; 4. Check whether the scrambled separator pipe of the solar water heater is damaged, if the separating pipe is damaged, you can replace the separator pipe with a new one; 5. If the temperature of the solar water heater is too high or too cold, you can adjust the temperature adjustment handle of the solar water heater to adjust the water temperature.

The normal amount of hot water output is that the rural household solar energy is only under low pressure, while the tap water pressure is high, and the mixing valve is not good at adjusting the water temperature.

Follow the steps above.

What is the step, that is, whether the tap water pressure can be reduced is similar to the hot water pressure.

1.Inspect the water lines to make sure they are in good condition; 2.Check the water bureau pressure control valve to ensure that it is in normal working condition; Kirizhiyou 3

Check the water tank to ensure that the tank capacity can meet the demand for water consumption; 4.Adjust the pressure of the water pressure regulating valve to reduce the tap water pressure; 5.Regularly inspect the water pipeline every month to ensure that it is in normal working condition; 6.

The installation of a throttle valve can limit the pressure of the tap water and make the pressure of the tap water and hot water reach a balance; 7.The water pressure compensation device can be installed to adjust the water pressure according to different conditions, so that the tap water and hot water pressure can reach a balance.

Hello, this is caused by the small water pressure, you look at the water pump to see if it works, if it doesn't work, then you can only put the solar energy higher.

Step 1: Set the solar controller to supply water at a regular time, and stagger the peak period of cold water consumption.

The solar controller can set three water supply time periods, and each time period can set the water supply independently. If the water cannot be loaded normally within the set time, the controller will automatically turn off the water supply, and repeat the water feeding action after half an hour until the water supply reaches the set water level. In general, the peak hours for cold water use are between 6 a.m. and 8 a.m., between 11 a.m. and 1 p.m., and between 18 p.m. and 10 p.m.

The first solar water supply period can be set between 4 a.m. and 6 a.m., and the liquid level can be set at 100%, the second water supply period can be set between 14 p.m. and 16 p.m., and the liquid level can be set at 100%, and the third water supply time period can be set around the peak period of cold water use. You can also leave it unset.

Step 2: Use a pipeline booster pump to replace the original water supply solenoid valve.

If the above method does not solve the problem, the second step is required. If there is no problem with the indoor water supply, only the solar water supply problem, the solar water solenoid valve can be replaced with a pipeline booster pump. Because the power supply voltage of the solar controller is 12V (or 24V), and the power supply of the water pump is generally 220V, it is necessary to use the contactor of the 12V (or 24V) control coil to solve the voltage problem.

The specific operation method is: connect the solar water solenoid valve power supply to the contactor control coil, and at the same time lead the 220V power supply to the contactor inlet line after the air is opened, and the outlet line can be connected to the water pump (the electrical part is recommended to find a professional electrician to solve).

Step 3: Use a pipeline booster pump to pressurize the cold water throughout the house.

If there is also a pressure problem with indoor cold water, a cold water pressure pump can be installed on the floor where the municipal water pressure can stabilize the water supply, and the pressure can be controlled. When indoor water or solar water is on the water period, the water valve is opened, the pressure of the cold water pipe drops, the water pump automatically opens, and it automatically closes when the set pressure is reached. This solution can not only solve the problem of low water pressure on the solar energy, but also solve the problem of cold water supply for the whole indoor.

It should be noted that if the pressure at the water point other than solar energy is too large, a tee can be connected behind the booster pump, and a pressure reducing valve can be installed on the cold water supply pipeline entering the room.
