With the popularity of commercial water heaters, more and more people should pay attention to how to maintain commercial water heaters. If the company's water heaters can't work, what should you do? Let’s take a look
l Common Faults and Solutions of commercial solar water heater
l How do you maintain commercial solar water heaters?
l commercial solar water heater is very sunny weather why the temperature of water is not high?
There are generally the following reasons:
1) There are trees and tall buildings above the water heater. A kind of
2) The upper water valve is not tightly closed, and the hot water in the water tank is jacked out by tap water (cold water). A kind of
3) The excessive sediment in the water (such as well water) deposits in the vacuum tube, which affects the heat collection and circulation. A kind of
4) Local air pollution is serious, and there is dust on the surface of vacuum tube. A kind of
Solution:
If the above problems exist, the first is to remove the occlusion or re-select the installation location. The second is to replace the water valve. The third is to dismantle the water heater and flush it with detergent and clean water, which is an example. Fourth, just scrub the vacuum tube.
l It took nearly an hour to get water in the morning, but when it was used in the evening, there was not much water. It seemed that the water tank was not full?
Solution
In this case, first check whether the tap water pressure is adequate. If the pressure is not enough, a micro pump can be added. Second, see if the water pipe is leaking. Replace piping, valves or connectors if there is a leak. The third case may be that the water tank itself leaks, at this time only to replace the water tank or re-weld the water tank.
l Why does the commercial solar water heater leak?
One is that the water tank is not correct when the sealing ring is damaged or installed. The solution is to replace the sealing ring or reinstall it so that the water tank is aligned with the vacuum tube. Second, open welding of inner tank. Professionals can be invited to repair welding or replace the gallbladder. Third, some pipe fittings inside or outside are bad.
l Sometimes in the shower, the water temperature changes from cold to hot, which makes it uncomfortable to wash?
This is due to the high and unstable pressure of the water tank.At this time, users can add a secondary water tank on the roof, which can not only store cold water but also stabilize the voltage.Add cold water or use an automatic temperature control valve.
l In winter, hot water can't come down, but cold water pours out a lot?
1) Water pipes are frozen in severe winter.
2) The weather is too cold. No heat preservation. At this time, the distributor can insulate the pipeline, or heat the pipeline with an electric heating anti-freezing belt (plate).
In addition, the use should be skilled: first, empty the water tank after using hot water in the evening, and water in the morning the next day. The second is to open the hot water valve on the coldest nights and slowly drip out hot water to prevent freezing. Nowadays, many manufacturers emphasize on the standard of easy use in winter, and commercial solar water heaters are becoming more and more useful in winter.
1. When installing commercial solar water heater, there may be dust or oil in the pipeline. When first used, the faucet can be turned on to remove impurities.
2. The water stored in commercial solar water heater should be discharged regularly according to the local water quality. The drainage time can be chosen in the morning when the collector is at a lower temperature.
3. The surface of commercial solar water heater can be cleaned by itself when it rains, and the high efficiency of heat collection can be achieved by keeping the surface clean.
4. When hot water is not used on continuous sunny days, the temperature of hot water is very high. When using commercial solar water heater, please boil cold water first, then hot water to avoid scalding.
5. The outlet end of the tap generally has a filter device. The scale and debris in the water pipe will gather in the net. It should be removed and cleaned regularly, so as to increase the flow of water smoothly.
6. In winter, it is very common for pipelines to be frozen. If it is found that the pipeline has been frozen but the pipeline has not cracked, the pipeline can be automatically dredged after the temperature rises. You can also use a hair dryer to blow, or wrap a towel around the water pipe, and then slowly pour it with warm water. You must not use fire to bake, tap the pipe or hot it with boiling water, which will burst the pipe. It is easy to freeze and crack pipelines due to multiple freezing blockages, so it is necessary to strengthen pipeline insulation measures.
7. commercial solar water heaters need to be cleaned, inspected and disinfected every two to three years on average. Users can also do some disinfection work by themselves at ordinary times. For example, they can buy some chlorine-containing disinfectants and pour them into the water intake, let them soak for a period of time, then release them, which can play a certain disinfection and sterilization effect.
8. commercial solar water heaters need to clean up the inner part of the vacuum tube for two to three years on average to prevent scaling in the inner part of the vacuum tube from affecting the endothermic effect.
9. If commercial solar water heater is equipped with special instruments, attention should be paid to lightning protection and electricity protection. When lightning strikes, do not take a bath and pull out the electric heating plug.
Secondly, it is also important to check whether the leakage protection device works well. In addition, if conditions permit, the water tank should be cleaned at intervals. In a word, no matter the electric heat pipe of solar water heater or other liquid electric heat pipe can not be separated from the liquid dry burning. Otherwise, it will cause the internal temperature of the electric heat pipe to be too high and cause the electric heat pipe to burn out, which will lead to potential safety hazards..For evacuated tube solar water heater, residential olar water heater pressurized solar water is same applies .
