The first reason for this situation is caused by weather problems; the second reason may be that the collector surface is blocked by dust and other foreign objects, resulting in poor heat absorption performance, so it is not hot; the reason may be It is possible that the valve or vacuum pipe is defective or damaged. If the collector is blocked, check and resolve it yourself; If it is an internal fault that non-professionals cannot handle, you need to call a technician to repair it. Possible causes of solar power failure include: Hot and cold water leaks. Check the valve at the water supply, then examine the double valve connecting the cold and hot water and see if the valve filter is blocked. The water supply pressure may be insufficient. If the automatic water supplykeeps working, the water released will naturally be cold water flowing, because there is no water in solar energy. Manual water supply valve does not close tightly. If there is no problem with the above valves, it is suspected that the solar vacuum tube has burst, so the water is not hot. Check the vacuum tube. When checking the vacuum tube, pay attention to see if there is an air leak at the tail, which is the reflective coating at the bottom. If the coating is no longer visible, this means that there is no air insulation due to air leakage, therefore. the water is no longer hot.
The reason why solar energy is not hot and how to deal with it
Because the amount of sunlight received by the solar tube is small and cannot be converted in time, the low heat leads to low heating water temperature. Usually due to continuous rainy weather, the vacuum tube breaks and the air is mixed, or the solar pipe is blocked by something. It is exposed to bad weather all year round and the surface is too dirty, which affects heat absorption.
The reasons for the low water temperature of solar water heaters are summarized as follows: 1. Continuous rainy weather and dark clouds cover the sun, resulting in low solar heat absorbed by solar pipes. Therefore, the water temperature. hot water is low on those days, and the storage capacity if there is less, you can use the electric heating function for heating. When rainy weather arrives, you can boil water in advance to prepare a reserve. 2. The outer pipe is too dirty and full of dust and impurities, which affects the communication between the pipe and sunlight. Solar water heaters mainly rely on metal pipes eexternal to absorb and convert solar energy. If there is something blocking the sun or covered with dust on the external pipes, it will affect direct sunlight. Exterior pipes should be cleaned of dust and debris. 3. The heater is damaged, the water level sensor fails, and the cold water level cannot be detected. The heat collecting tube has a damaged opening through which air or scale impurities enter, and the vacuum state is lost, preventing effective heating. carried out. The vacuum line should be cleaned or repaired, then the water level sensor should be inspected.
What is the reason why solar water is not hot?
The reasons why solar water is not hot and how to deal with it are as follows:< /strong>
1. There is a lot of dust deposited on the surface of the collection tubevacuum tor and reflective plate or there are obstructions; the vacuum collector tube leaks and loses vacuum; The weather is bad, the solar radiation energy is insufficient, and the temperature is low; the water tap is not closed tightly and is in a slow water supply or drainage state.
Troubleshooting:Take the following measures according to the above fault causes: wipe off the dust on the surface of the vacuum collecting tube and reflector, remove the obstruction; replace the vacuum collection tube; use an electric space heater; the valve to make it tight or check the quality of the valve, replace the parts of the water valve.
2. The water in the water tank has been drained; the pipe interface is loose or blocked; upper and lower water pipes freeze in winter; the vacuum collector tube is damaged or the silicone ring falls off.
Dice Methodspannage: fill up with water; troubleshoot loose or blocked pipe interfaces; improve pipe insulation and install heat tape or antifreeze; replace the vacuum tube or silicone ring after checking.
3. The external water supply is cut off or the water pressure is too low; the water pipe interface is loose or damaged.
Troubleshooting method: Wait until the water pressure is normal; check and maintain the pipeline.
4. The pipeline interface is loose or blocked; the vacuum collector tube is damaged and the silicone ring falls off and leaks.
Troubleshooting methods: check and maintain the pipeline; replace the vacuum collection tube; reinstall the silica gel ring or replace the silica gel ring.
5. Tap water pressure is low.
Troubleshooting method: stop filling the water and wait until the water pressure is normal beforet use it.
6. Tap water pressure fluctuates.
Troubleshooting method: Do not open another tap water faucet or use a bathtub when bathing.
Precautions for using solar water heaters
1. Estimate the required capacity of the water heater based on the number of family members and usual bathing water consumption, and avoid it. oversized or oversized water heaters. Small, if your needs are important, you can try to choose one with a larger capacity.
2. Before going out tomorrow morning, decide the amount of water according to the weather conditions to ensure the appropriate water temperature when taking a bath in the evening.
3. Check regularly to see if the pipes, vents and other components of the water heater are working properly. And rinse the vacuum tube regularly to avoid clogging and affect the effectof heating.
4. When cleaning the water heater, it is best to follow the installation instructions for disassembly and cleaning. Do not move, load or disassemble the entire machine easily to avoid damage to key components.
Possible reasons are: 1. There is an obstruction; 2. The water supply valve is damaged or improperly closed; 3. Water quality is poor; 4. Air pollution; Water consumption Large; 6. Short lighting time; 7. Dust in the collection tube 8. Quality problems with the insulating layer; Suggested solutions: 1. There is an obstruction above the water heater, or there is a lot of smoke and dust in the local air, and there is dust on the surface of the heat collecting tube. Then remove the overhead obstruction or relocate the solar power. 2. Keep the water tank in a slow filling or leaking down state. The water iswater in the water tank is overflowing or leaking. Then replace the water ball valve. 3. Due to poor water quality in the area or homeowner, there is scale in the vacuum tubes, reducing the efficiency of heat collection. Able to clean the inside of the vacuum tube. 4. Local air pollution is serious, and there is dust on the surface of the vacuum tube, which affects heat collection. Clean the surface of the vacuum tube and condenser grille. 5. All the hot water in the water tank is used up, that is, there is no basic water temperature. The water tank capacity is small and the water consumption is large. Replace it with a large capacity water heater or add water. Install an electric heating system. 6. Mainly due to low irradiation or short lighting duration in rainy and foggy weather. 7. If there is dust on the surface of the tube collector, clean the surface with a small amount of water when disassembling and reassembling the collector tube. 8. The vacuum tube should be replaced with a new one if the vacuum degree drops.
