The reasons why the solar water heater cannot discharge water are:
1. The water in the water tank has been drained and heated in the sun before use.
2. If the hose interface is loose or blocked, reconnect it or clear the hose.
3. In winter, water pipes can freeze. It will melt on its own about 3 hours after sunrise. In cold areas, a drain valve can also be installed.
4. The upper and lower water valves are leaking, the water supply valve is also leaking, and the water pipe has been dry for a long time, causing water to flow back. This situation requires repair and solution.
5. The nozzle valve or hot water nozzle is malfunctioning and is not actually open, so it needs to be repaired.
I hope to adopt it, thank you!
Why can't solar energy produce hot water?
1. The water pressureThe tap water pressure is too high
In the solar water heater, the tap water pressure is too high. If it is too high, hot water will not flow. We need to reduce the flow of tap water or add a booster pump. Once the tap water pressure is balanced, hot water can flow. We usually use water heaters very frequently, so we always need to pay attention to the water pressure to avoid excessive water pressure.
2. Vacuum tube problem
Many families install vacuum tube solar water heaters. Vacuum tubes are important components for absorbing solar heat sources. If the vacuum tube is not cleaned for a long time, it will affect the heat absorption capacity, and only cold water will come out, but no hot water will come out.
Evacuated tube solar water heaters absorb heat and heat up quicklysunny summer days. If no one at home uses water for a long time, the water tank will be at high temperature and high pressure. condition for a long time, which will cause the water tank to age, problems will occur, and it will not be able to pump water. Additionally, the vacuum tube is damaged, resulting in insufficient heating and the solar water heater will not produce hot water.
We must clean the vacuum tube in time. If it is damaged, it should be replaced in time. If no one is home for a long time, a cover should be placed over the vacuum tube to block the tube. sun.
3. Water leakage problem
One of the reasons why the solar water heater does not produce hot water is the water leakage problem. There are many pipes when installing a solar water heater. If cold water comes out, there may be a water leak. This phenomenon requires the insinstallation of an independent valve and closing of the valve to avoid hot and cold flows.
4. Impact of Fully Automatic Auxiliary Water Tank
If the float valve of the fully automatic auxiliary water tank is not closed tightly or fails, it will cause more cold water and a lower of temperature. water temperature, and what flows out is not hot water. Fixing this problem requires replacing the float valve and associated parts.
5. Leaks in sewer pipes, valves or joints.
Pipes and their components are usually outdoors, exposed to wind and sun, and are easily damaged. If problems arise, they must be repaired. repaired and replaced in time.
Detailed information:
1. Vidang the system regularly to prevent blocked pipes, cleaning the water tank to ensure water quality; cleaning. When discharging sewage, simply open the sewer valve until clean water flows from the sewer valve while ensuring a normal inflow of water.
2. Regularly remove dust and dirt on the transparent solar collector cover and keep the cover clean to ensure high light transmission. Cleaning work should be carried out early in the morning or evening when the sunlight is not strong and the temperature is low to prevent the transparent cover from being broken by cold water.
3. Pay attention to check whether the transparent cover is damaged, replace it in time.
4. For vacuum tube solar water heaters, always check the vacuum degree of the vacuum tube or whether the inner glass tube is broken. When the baryu getterm-titanium of the vacuum tube turns black, this means that. the vacuum level has dropped and must be replaced.
When using a solar water heater, sometimes the water is hot but no water comes out. When this happens, many people don't know how to deal with it. So let me explain to you why solar hot water cannot be released.
1. Why solar hot water cannot be released
1. Solar sewer pipes and joints leak, preventing hot water from being released. 2. The tap water pressure is too high and hot water cannot be discharged. Tap water should be turned down. 3. A water leak occurs in the solar water heater, preventing hot water from escaping.
2. How to clean scale from solar water heater
1. When cleaning the solar water heater, first turn off all the water in the water tank, then turn on the vacuum cleaner. tube and wait for the bsealing gap of vacuum tube and water tank. When it is loose, push it back into the water tank. Once the vacuum tube is completely loosened, remove the water tank.
2. Pour the water into the vacuum tube so that the scale comes out with the water, then pour clean tap water into the vacuum tube to clean it, and repeat the cleaning several times in succession. to clean the vacuum tube, then check whether the water tank vacuum tube sealing ring is intact. If damaged, the sealing ring should be replaced to prevent water from the water tank from leaking out of the vacuum tube seal. ring.
3. The water tank is filled with water. When water flows out of the vacuum tube, install the vacuum tube on the water tank. In this way, the work of cleaning the scale is completed. In addition, regular cleaning of scale inside the solar water heater can be based on the local conditions of qwater quality. Do not clean it frequently.
4. When using solar water heaters, ensure that the water temperature in the water tank is below 75 degrees, so that scale is less likely to occur in summer and autumn. be determined based on weather conditions. If there is sufficient sunshine, the water in the water tank should be added as needed, so that the water temperature drops as tap water is added to prevent scale generation .
