Cleaning of solar water heater how to clean gas water heater

Although water heaters are very common now, there will be some differences between the water heaters that you use. If you need to clean the water heaters, you must be sure that different water heaters have different cleaning methods. You need to pay attention to this. Next, you will learn about the cleaning of solar water heaters and how to clean gas water heaters Washing related issues. First of all, the cleaning of solar water heater is to dismantle the solar pipe, and pour the scale inside out with the removed pipe mouth facing down. If it's not easy to pour, it's easy to pour after natural weathering. It's OK to poke it with a plastic rod. The scale in the solar energy water storage tank needs to be removed. Add water with the mouth facing up, and quickly move the mouth down during shaking. The scale and water rush out together, and assist the small spoon and other things to pull out. Finally, rinse with water. So far, solar cleaning is complete. How to clean the gas water heater? 1. The shell and filter screen. For the gas water heater, when it is relatively not dirty, you only need to use a wet cloth to remove the dirt. But if the dirt is heavy, the user needs to use a cleaner to clean it carefully. After a long time of use, there will be a lot of scale and dirt on the filter screen of the gas water heater, so users need to screw out the water valve and take out the filter screen to clean it. 2. Water tank, generally, the water tank is a part that is easy to block, so users need to carefully check whether the water tank is piled up with scale, dirt, etc. when cleaning, if any, they can use wire to pull it out. But if you don't know the cleaning method, you can ask professional after-sales maintenance personnel to clean it. 3. Induction needle and ignition needle, induction needle and ignition needle are important factors that affect the fire of gas water heater. If poor ignition effect is found in daily life, it may be because of problems of induction needle or ignition needle. The solution is: wipe gently when cleaning, do not use too much force to avoid bending the needle. 4. Gas pipe and gas pipe are generally made of rubber, so the obvious disadvantage is that they are easy to be covered with dirt, and many users choose to install the water heater in the kitchen, so the problem of oil pollution is very prominent, users can use detergent to clean the oil on the gas pipe. The previous article is about the cleaning of some solar water heaters and how to clean the gas water heaters. It can be seen from the above article that there is a big difference between the cleaning methods of solar energy and gas water heaters when cleaning the water heaters. When cleaning the water heaters, you should pay attention to which one you use Species.

Some experience in using solar water heater

Myth 1: solar water heaters cannot be used in cold areas with insufficient light Lack of light is indeed a big enemy of solar water heaters, but with the progress of heat absorption and insulation technology, solar water heaters can still appear in the place of lack of light. The heat absorption performance of solar water heater is closely related to its vacuum collector. The collector tube should be able to absorb visible light to the maximum extent, and the collector performance and stability can be compared. In the cold weather, solar water heater not only has to face the problem of insufficient illumination, but also has to overcome the problem of tube explosion related to vacuum tube. If the power of the vacuum tube is greater, the solar water heater can still provide continuous hot water in the cold area. Myth 2: solar water heaters "stop cooking" in rainy weather. Most solar water heaters are now equipped with electric heating, which also reduces the impact of the weather on them. According to my personal experience, in rainy days, the water temperature heated by solar water heater is estimated to be more than 30 ℃. Generally speaking, the hot water we use only needs about 40 degrees. When bathing, you can turn on the electric heater. The water temperature will rise soon, much faster than the electric water heater. Mistake 3: if equipped with electric heating equipment, there will be safety risks. The poor quality solar water heater lacks the protection function of electric wall, and its safety performance cannot be guaranteed after equipped with electric heating. For this reason, the solar water heater should work on the wall. Myth 4: solar water heaters are expensive Compared with electric water heater or gas water heater, the purchase cost of solar water heater is generally slightly higher. However, from personal experience, its use cost is the lowest of the three. From the perspective of energy, gas water heaters use non renewable natural gas, which not only pollutes the environment, but also has high cost. But the electric water heater has high power and small water storage capacity. If you want to get water at any time, you must keep the electric water heater online at any time, which will cause a lot of power waste. The solar water heater uses clean solar energy and has low cost. Even with electric auxiliary heating, the heating time is short and the power consumption is relatively small.

The reason and solution of water insulation of solar water heater

For solar water heater, the reasons for water not hot are as follows: 1. There is a protective cover above the water heater or a large amount of local air smoke on the surface of the collector. 2. Step 2. The upper valve is damaged or not closed in place, so that the water tank is in a slowly upward or downward leakage state, and the hot water in the water tank overflows or leaks. 3. The water quality is not good. The existence of vacuum tube scaling reduces the heat collection efficiency. 4. The local air pollution is serious, and there is dust on the surface of vacuum pipe, which affects the heat collection. 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. 6. Cloudy, rainy and foggy weather with low irradiance or short exposure time. 7. There is dust on the surface of gas collecting pipe. Remove and assemble the collection pipe and clean the surface with a small amount of water. 8. The vacuum degree of gas collecting pipe is reduced. The new vacuum tube needs to be replaced and cannot be used continuously. 9. There are few quality problems in the insulation layer, but they still exist, that is, there are large foaming holes in the insulation layer. The probability is generally less than one thousandth of a thousand. Consumers must choose brands or manufacturers with good quality to purchase. 10. The original solenoid valve of the water level controller can not be installed or programmed or controlled for water supply. The water supply is too large or mixed with the cooling water pipeline. In this case, professional personnel are needed for debugging and maintenance. Damaged parts shall be replaced in time to avoid affecting the use. 11. Leakage may also occur. If the water temperature and water level meter with automatic water supply function are installed, once the solar energy leaks, the solar energy is generally debugged during the installation process, mainly the water level meter debugging. As long as it is tested, the probability of water leakage is very small. The solution is as follows: 1. Shield removal or solar energy conversion; 2. Replace the water ball valve; 3. Clean the vacuum pipe; 4. Clean the surface of vacuum pipe and grid; 5. replace large capacity water heater or install electric heating system; 6. Analyze the weather and pay attention to the water volume on the water heater; 7. Start the auxiliary electric heating device in the solar water heater.

Knowledge solution for water supply of solar water heater

Water supply time of solar water heater: The best choice of water supply time of solar water heater is to supply water for two hours before or after sunrise under the condition of non high temperature air drying. This is because the collector plate of the solar water heater can quickly collect heat and keep warm, so if the solar water is heated in the high temperature air, because the water temperature is relatively low and the solar energy temperature is high, it is easy to cause failure, because the f temperature difference is large. In daily use, the water heater should be heated for one sunshine day as much as possible after the water supply, so that the long sunshine can maximize the water temperature. If the water is supplied immediately after that night's use, it is easy to affect the water temperature of the next morning, and then add water later. After bathing in winter and spring, if the temperature of half of the hot water in the water tank of the water heater is between 60 and 70 ℃, it should be filled in the evening to prevent overheating loss.
