If the solar water heater is not heating, it is very likely that there is a screen in front of the solar water heater, so that the collector tube of the solar water heater is not not exposed to sunlight, or the exposure time is too short, and naturally it cannot be heated.
In this case, you just need to remove the obstruction on the solar wall. If the obstruction cannot be moved, you may consider moving the solar to a location with better sunlight and longer duration. .
There is dust on the surface of the solar collector tube, which affects solar heating. If this is the case, you can remove the collection tube, clean it with clean water, and then reinstall it. The reduced vacuum degree of the collector tube will also affect the heating of the solar water heater. In this case, the only way to replace the vacuum tube is with a new one.
Other reasons qui affect the water temperature of solar water heaters:
1. Water quality There are too many metal ions (hardness) in tap water. , resulting in the generation of heat-absorbing vacuum tubes and the heat transfer performance of scale is relatively poor, which directly affects the heat exchange efficiency.
2. Neglected maintenance. Although the solar water heater consumes very little money in the later period (excluding electric heating), too much debris or dust is absorbed outside the solar vacuum tube or heat collection. plaque, which will result in In order to reduce the efficiency of heat collection, the heat absorbing surface should be cleaned regularly, especially in places where air pollution is serious, the cleaning frequency should be increased.
3. The quantity of water is not sufficient. This is linked to water consumption initially cunconceived. If hot water is used for a long time or a large number of people use it, more hot water is used. necessary, and the water heated by the water tank will not be enough. It must be reheated after use. If it is night time, the water in the water tank should be fully heated by electricity.
What is the problem if the solar water heater does not heat?
The solar water heater does not heat for the following reasons:
1. There is a screen, short daylight hours.
2. The water valve is not strictly closed.
3. Water quality is poor and vacuum tube memory reduces heat collection efficiency.
4. The local air pollution is serious, and there is dust on the surface of the vacuum tube, which affects heat collection.
5. All the hot water in the water tank is used up, that is, there is no base temperature of thewater, the water volume in the water tank is small and the water consumption is large.
6. Affected by weather.
The solutions are as follows:
1. Remove the obstruction or solar replacement device.
2. Replace the water supply ball valve.
3. Clean the vacuum tube.
4. Clean the surface of the vacuum tube and focusing grid.
5. Replace a large capacity water heater or install an electric heating system.
6. Analyze the weather and pay attention to the amount of water on the water heater.
Detailed information
Water heater maintenance:
1 When installing a solar water heater, there may be dust or oil inside. the smell from the water pipe, you can open the faucet when using it for the first time. Remove the debris first.
2. The water stored in the solar water heater must be keptsharpened regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smooth the flow.
1. The solar water heater does not heat. There may be a problem with the vacuum tube, which is blocked by scale, which will also affect the heating effect.
2. On the other hand, it is also possible that the upper and lower water valves are not tight, which will also affect the heating effect. After all, sunlight absorbs heat. If the sunshine duration is short or there is something on the vacuum tube that blocks sunlight, this will also cause lack of heating.
3. Sometimes it's because the weather is bad and there's no sun. In this case, the water heater cannot start heating.
4. Another reason is that the water capacity of the water heater tank is relatively small, and the water inside is exhausted, but the water is not added in time. Without the base temperature of the water, it will naturally not heat up.
If the energysolar does not heat, we can solve it according to the reason. For example, if it rains, it is an objective factor. When the sun rises and the weather is clear, it's time to heat the house.
If a lot of dirt accumulates in the vacuum tube, it should be cleaned regularly to remove the dust inside, which will improve the heating effect.
Also note that if the upper and lower water valves are not closed tightly, you can tighten the upper and lower water valves. Also, if something is blocking the sun's rays, remove any light-blocking obstacles so that the sun's rays can shine directly onto the heat collecting plate.
The water heater must be filled with water. If the weather is nice the next day, you can fill it with water the day before. After a sunny day, hot water can be used in the evening.
