The solar water return pipe is broken, and the water is almost full after how long it takes

It depends on the size of the water pressure and the capacity of the water tank, which generally ranges from 10 to 30 minutes.

Return pipeThe return pipe is to connect a pipe at the end of the hot water pipe and then extend to the side of the hot water pipe of the water heater, which is called the return pipe, and the return pipe and the water heater are the same pipe, that is, the hot water pipe is extended to the water heater position. This design is needed when the central hot water supply is centralized, that is, there are two pipelines from the water supply point to the water outlet, one is the hot water supply pipe and the return pipe, the hot water supply pipe will cool after a certain period of time, in order to ensure that the water outlet has hot water in a short time, then when the hot water is cooled to a certain water temperature, it will be automatically pumped back by the water pump to reheat from this return pipe.

Return pipes. Return pipe definition.

A return pipe is a section of pipe that passes only the circulating flow in the recirculating pipe system. Return pipes.

Classification of return pipes.

1. No return pipe: It is to install a set of check valves (check valves, only flowing water to one side, not backflow) under the washbasin at the farthest point of the water heater to achieve the circulation effect.

2. There is a return pipe: the one with a return pipe is to install a check valve at the end of the return pipe to connect to the cold water pipe, and directly pump back the cold water from the hot water pipe to the cold water pipe.

Solar water heaters have been increasingly favored by consumers for their safety, energy saving, large water volume, wide use, and convenient use. However, in use, due to its outdoor setting, under the influence of low temperature weather in winter, it is especially necessary to pay attention to the anti-freezing problem of the pipe when using. Here are a few commonly used methods of freeze protection:

1. Commonly used anti-freezing: When the vacuum tube solar water heater is used normally on a sunny day in winter, when the temperature is lower than 0, it is best to use a small amount of water in the water heater several times a day. Especially before going to bed and after waking up, put a small amount of water to make the water flow in the pipe, relying on the water temperature to increase the temperature of the pipe.

The lower the temperature, the more water should be released to prevent the pipe from freezing and blocking. 2. Drip anti-freezing: usually pay attention to the weather forecast, when the temperature drops below 7, fill the water tank with water after using up the hot water at night.

After that, connect a basin under the sprinkler or faucet, loosen the hot water valve a little, and let it drip slowly, so as to maintain the flow of water in the pipeline. 3. Venting and anti-freezing: If the pipeline is not reversed during installation, after using up the water, the water heater can be emptied, and the drain valve can be kept open, so that the pipeline will not be frozen and blocked.

4. Electric heat tracing antifreeze: connect the electric heat tracing directly to the power supply, so that it works all the time, without any control system, and is operated by the user. 5. What to do if you freeze and block:

After the temperature rises, it can be automatically dredged, and if there is a water leakage, the manufacturer or after-sales service department should be notified immediately for timely maintenance. Four ways to prevent freezing of water supply and water pipelines in solar water heaters.

There are many reasons why the solar return pipe does not return water, it may be that the pipe of the equipment is damaged, and the pipe can be replaced to solve it; It may be that the water pressure is not enough, and you need to add water before use; It may be that the automatic controller is faulty, resulting in an error in signal transmission, and you need to contact the after-sales service; It may be a solenoid valve problem, the solenoid valve needs to be replaced, and the equipment needs to be used for precautions: 1. The solar energy cannot set the heating function, it may be that the vacuum pipe is damaged and needs to be replaced in time, 2. The solar water heater cannot be used, it may be caused by the fouling of the internal electric heating rod, and it needs to be disassembled and cleaned, 3. The solar water heater cannot be used, it may be caused by the disorder of the controller program, and it needs to be contacted for after-sales treatment, 4. The solar water heater cannot produce water, it may be that the upper and lower water pipes are blocked, and it needs to be dredged in time. It is recommended to choose an hour before sunrise and after sunset before the water, 5, the solar water heater can not be on the water, may be the float structure is damaged, need to replace parts to solve, data expansion: solar water heater is a heating device that converts sunlight energy into heat energy, heating water from low temperature to high temperature, to meet the use of hot water in people's life and production, solar water heater is divided into vacuum tube solar water heater and flat panel solar water heater according to the structural form.

There are many reasons why the solar return pipe does not return water, it may be that the pipe of the equipment is damaged, and the pipe can be replaced to solve it; It may be that the water pressure is not enough, and you need to add water before use; It may be that the automatic controller is faulty, resulting in an error in signal transmission, and you need to contact the after-sales service; It may be a solenoid valve problem and the solenoid valve needs to be replaced.

One is that the water is too full, and when the sun comes out, the heat convection will quickly expand the water in the water heater, and the expanded water will overflow from the return pipe. This situation is not a "problem", and once the water temperature reaches its maximum value, it does not continue to overflow. You can also take the initiative to use some of it, and it will stop dripping immediately.

The second is that the water switch is not tight, there is always a small amount of cold water constantly injected into the water heater, and the return pipe naturally keeps backing water, which is really a "problem". Repairs are needed.

It could be that the return pipe is blocked.

The reason for this is that the elbow is directly connected to the overflow pipe. 2.Valve damage:

If the water supply valve is damaged, drain the water in the solar energy, and then turn on the shower to close the water supply valve. 3.Tube freeze cracking:

Many solar tubes are frozen in winter. 4.Notes:

The solar water heater cannot be put into the water, and to stop using the equipment, ask a professional to deal with it.

1. It may be due to thermal expansion and cold contraction, which is due to the overflow pipe directly connected to the elbow. The normal one is generally a tee, and the water vapor will be discharged into the air through another hole, and will not condense into water dripping, and it will not drip on cloudy days or without sun. 2. The water valve is broken, put the solar water out, and then open the shower to close the water valve, if the valve is bad, the shower will drip slowly.

3. Many solar winter tung barrage days are frozen and damaged pipes, that is, because of the slow water, so the water pipes are frozen and cracked, and most people do not pay attention to think that it is not a problem with the valve.

1. The return pipe of the solar water heater is an overflow pipe, and the overflowed water flows out through this pipe after being filled with water, and it is reasonable that the flow should stop after a while, but in sunny weather, the solar energy is constantly heating, the water temperature is rising, and the water is expanding and shrinking above 4 degrees, and the water level in the solar water tank will rise slowly, higher than the overflow port, so there is water flowing out, giving people the feeling that it is always flowing water. In fact, it is a normal phenomenon.

2. You are too full on the water, after the daytime sunshine, due to the reason of thermal expansion and contraction, the water may be dripping during the day, and the water is not hot, that is, the water valve of your home is not closed strictly (it needs to be replaced) or there are places where hot and cold water are channeling each other. I hope it can help you, thank you for your support, come on!

If there is a small drop of water falling in the summer, it may also be caused by the thermal expansion of the water in the tank.

Check if the water switch has been on the water, I really help you look forward to it

It's because, first, the switch on the water supply is broken; Second, the water is too full.

The first case is when the valve is broken. First check the valve to see if there are cracks or dripping, if there is, please switch the water source master and replace the valve. In the second case, if the valve is not broken, it is because the water is too full, and it overflows after heating and expansion after being filled with water, and it will not drip when it is released after it is full.

When the sun comes out, the heat convection will quickly expand the water in the water heater, and the expanded water will overflow from the return pipe. This situation is not a "problem", and once the water temperature reaches its maximum value, it does not continue to overflow. You can also take the initiative to use it to grind some indiscriminately, and it will stop dripping immediately.

Lucky friends. As for the specific situation, the water switch of the solar water heater is controlled by two ceramic sheets, and if there are tiny sand particles between the ceramic sheets, there will be leakage. If you have hands-on ability, you can fix it yourself. First close the main water pipe, clean the water heater and store water, remove the fixing screw from the water switch cap, remove the switch handle, unscrew the switch body with a wrench, remove the ceramic sheet and clean it, adjust the rubber gasket at the top, and then install it back to solve the problem.

If you lack the relevant knowledge, you have to pay a professional to repair it.

If one of the solar tubes is broken, it can still be sent to the reputation of the water.

**A pipe can still be used, but it is recommended that you replace it as soon as possible, because if you don't replace it, the heat loss is relatively large, and the pressure type is not a separate water heater, which is commonly said that the tap water is stopped, and the water heater will not come out.

Tips for buying solar energy:

1. Thermal index.

It refers to the heating efficiency index of solar energy, which is mainly reflected in the higher the average daily efficiency, the better, and the lower the average heat loss coefficient, the better. Thermal index is one of the objects that consumers need to focus on when buying solar energy, for the current business, to build a brand, you need to start from the performance index of the product, the details determine success or failure, and the thermal index is the key to the solar brand.

2. a vacuum tube.

It is the key part of the solar water heater, which is the all-glass vacuum solar collector tube. The quality of the original will have a huge impact on the effect of solar energy. So when buying and consuming solar energy, look at the coating in the vacuum tube.

This coating is a solar selective absorption coating, and the color of the product will be different due to the different processes of the merchants. It usually comes in black, dark blue, and dark gray. Generally speaking, *** will be very uniform in coloring, and there will be no peeling, scratches, etc.

At the same time, there will be no stones, nodules and other conditions on the glass. <>

This is a normal phenomenon. The return pipe of the solar water heater is an overflow pipe, and the overflowing water flows out through this pipe after being filled with water, and it is reasonable to stop flowing for a while, but in sunny weather, the solar energy is constantly heating, the water temperature is rising, and the water is expanding and shrinking above 4 degrees, and the water level in the solar water tank will rise slowly and be higher than the overflow port, so there is water flowing out, giving people the feeling that it is always flowing water.

This design is needed when the central hot water supply is centralized, that is, there are two pipelines from the water supply point to the water outlet, one is the hot water supply pipe and the return pipe, the hot water supply pipe will cool after a certain period of time, in order to ensure that the water outlet has hot water in a short time, then when the hot water is cooled to a certain water temperature, it will be automatically pumped back by the water pump to reheat from this return pipe.

The water supply valve is broken, and it can't be closed all the time.

The solar overflow pipe and the cold water tank collude.

The overflow pipe of the solar is broken.

Is it installed with an automatic water meter, if it is possible that the probe is broken.

The possible reasons for answering are: 1. If there was no problem before, it happened suddenly, and it was a sensor failure; 2. The water supply and return pipelines are unreasonably connected in series and parallel with other waterways, and there may be water strings; 3. If the water heater is newly installed, it may be that the full water level test point of the sensor is higher than the return pipe. Whatever the reason, it is advisable to contact the merchant for repair as soon as possible.
