The reason why the geothermal return pipe is not hot

1. There is air blockage in the geothermal pipeline. Look at whether there is an air blockage in the pipeline, that is, the air in the pipe does not flow. At this time, the return valve should be closed, and then the exhaust valve on the return water should be opened, and each valve on the inlet water should be closed first, and then the exhaust should be opened all the way.

2. The water is not released at the end of the heating period. At the end of the annual heating period, the user should discharge all the boiler pipe water in the geothermal network. Otherwise, if the long-term scale is not removed, the flow rate will be reduced, the flow will be poor, the thermal radiation value will be reduced, and the pipe network will be blocked.

3. Defects in geothermal construction. The quality of the construction personnel is low, without professional training, barbaric construction, and the pipeline is dead bends and flattened, resulting in poor water flow and increased resistance. The spacing of the pipes does not meet the design requirements.

4. The geothermal pipe has not been cleaned all year round. After the use of the geothermal pipe, there will be biological slime and impurities, bacteria generated, and then due to the change of water supply temperature will produce calcium and magnesium ion scale attached to the inner wall of the pipeline for a long time, if not cleaned and maintained in time, the inner diameter of the floor heating pipe will gradually narrow, and the water flow will become smaller and smaller, which directly affects the heating effect.

1 Is the room warm? If it is not warm, it may be that the main pipe of the inlet pipe is blocked, the inlet water cannot enter and does not flow, and the backwater backs up, resulting in the inlet pipe not flowing and the backwater pipe is hot;

2. The room is warm, which may be due to the reverse connection of the water inlet pipe and the return pipe, resulting in the hot water return pipe and the water inlet pipe not hot.

3 If you say so, there may be other reasons, and it is better to call the heating company to take a look and repair it.

1. There is air in the geothermal pipe to cause air resistance, and the solution is to open the air release valve to release the air for about an hour.

2. If the water flow is slow because the filter is blocked by sediment or there is too much silt in the geothermal pipe, you can clean it yourself or find a geothermal cleaning company to clean it.

3. Check whether the lower return valve is fully opened (in the shape of "one" for open, and in the shape of "ten" for off).

4. If it is not solved after cleaning and degassing, in view of the low return water pressure in this situation, it is recommended to install a circulating pump to solve the problem.

In winter, the heating equipment of the home begins to be used, and geothermal heat is one of the main ways of home heating. There are many reasons why geothermal heat is not hot, which may be due to insufficient pipe pressure or pipe blockage.

1.The pressure in the pipes is not enough.

The pipes are not hot, and many times they will appear in the higher-rise families, because the floors are higher, and the pipe pressure of the water pipes is not enough, so the heating is insufficient. If this is the case, the best solution is to find a heating company or property to solve it, and if it is a geothermal problem, they will reinstall a circulating pump to improve the circulation of hot water and achieve the desired heating effect.

2.The loop is uneven.

Generally speaking, in the same community, other households have good heating effect, and their own heating effect is not good, this phenomenon is generally caused by the uneven circuit of geothermal return pipe. If it is the cause of uneven circuits, at this time, you can use the small valve on the water separator to mediate the circulation of each circuit, and the return pipe "ten" shape is closed, and the "one" shape is open, so that the geothermal energy can be evenly circulated to achieve the ideal heating effect.

3.Clogged pipes.

Geothermal pipes can easily lead to pipe blockages due to long-term non-cleaning, and in geothermal heating systems, the average annual return pipe will scale 1mm, and this 1mm thick scale will cause the water temperature to drop6. If the geothermal heat is not cleaned in time, the dirt will adhere to the inner wall of the pipe for a long time, and eventually the geothermal water pipe will not be hot. At this time, the best way to solve the problem of geothermal heat is to deal with stains in time, and now there are professional clean geothermal pipe products on the market, which can effectively remove sediment, dirt and scale, and completely solve the problem of geothermal return pipe not hot caused by pipeline blockage.

Many families will have the problem of geothermal heating not heating, but there is no need to worry too much, as long as the cause is found out and solved in time, the geothermal heat can be used normally immediately. If you don't have any experience yourself, you can also find a geothermal company to help you deal with it.

Ask if my house can be a low-stress thing, my house is vented.

If the exhaust is not clean, the heating will not be warm.

Question: My house is hot at the bottom, and I exhaust it myself.

Have a great day.

Generally, the outlet pipe is not hot, you see what the temperature of the house is, if the temperature is low, find the property or heating company, or you unscrew the valve a little, and exhaust it through the drain.

Many people will install floor heating at home and floor heating, it is inevitable that there will be some problems after a long time, such as the geothermal inlet pipe and the hot return pipe is not hot, what is the reason? And how to solve it? If you want to know more, you may wish to take a look at it together.

1. What happens if the geothermal inlet pipe and the hot return pipe are not hot.

1. If there is gas in the pipeline and it is not drained in time, it will also cause the water circulation to be not particularly normal, and the pipeline will not be particularly hot.

2. If the water pressure in the pipeline is not particularly sufficient, and the flow rate is relatively slow, it will also cause the return pipe to be not hot.

3. It may also be unreasonable when installing, for example, some masters lay the floor heating pipes too densely when installing, and if the water pipes are laid more intensively, the heating effect will be bad, because it will reduce the flow rate of the water pipes, which will affect the heating effect.

4. There are some new houses, the developer is not particularly reasonable at the beginning of the design, and the water separator is set too little, which will lead to the long backwater pipe and affect the water circulation.

Second, how to solve it.

1. If there is still gas in the pipeline that is not discharged, we need to open the exhaust valve, first of all, we need to drain the gas clean, if we see a water flow, it means that the gas has been discharged, and then close the water valve, which will make the heating effect improved.

2. If it is a problem of water pressure, it may not be an individual phenomenon, maybe other neighbors have similar problems, this may be that the water pressure provided by the heating company is not particularly sufficient.

3. If the floor heating pipe is laid too densely, pay more attention to it when laying it at the beginning, generally speaking, 4 meters of water pipes should be installed per square meter.

4. If the water separator is unreasonable, pay more attention to it, each component of the water separator can drive about 10 square meters, so it must not be able to save trouble when arranging, and the water separator must be fully prepared.

Summary: If the floor heating is not heated, we need to find out where the problem is in time, and then solve it one by one.

Hello dear<>

I'm so happy to serve you<>

1.There is air blockage in the floor heating pipe, and there is gas blockage in the warm water pipe, that is, air enters the geothermal pipe, which is blocked, resulting in the water not flowing. In this case, the return valve should be closed first, and then the exhaust valve on the return pipe port should be opened, and each valve on the inlet pipe should be closed first, and then the exhaust should be opened one by one.

After the gas is emptied, open the valve normally. Let's take another look at whether the inlet pipe has become hot. Whether this phenomenon is caused by gas gambling.

2.There is sediment in the floor heating pipe, if the previous floor heating is good, but this situation has just appeared. It is also possible that long-term use has caused some dirt in the floor heating pipes.

If it is attached to the inner wall of the water pipeline for a long time, if it cannot be cleaned and maintained in time, the inner diameter of the pipe will gradually shrink, and the amount of water will be reduced, thus affecting the heating effect. When the heating is about to run out, the moisture in it is not discharged in time, and there will be siltation, so we need to remove the sediment in the pipe, and we can choose a professional company to help us clean it up3Floor heating construction problemsWhen using floor heating coils, due to the lack of attention by construction personnel, the pipeline will be dead bends and pressure levels, resulting in unsmooth water flow and increased resistance.

It is also possible that the distance of the drain pipe does not match the design. At this point, we can't see it from the outside, if the floor heating was normal before, but now the return pipe is not hot, then it is not a problem.

Causes: 1. Gas blockage of geothermal water pipes

Air enters the geothermal pipes, causing the water to flow immovable.

2. The water was not drained after the end of the heating period of the previous year

After the end of the annual heating period, the user needs to take the initiative to drain the water in the geothermal water pipe and the boiler pipe. If it is not discharged for a long time, it is easy to cause stagnant water to scale and block the pipeline.

3. Dead bends caused by geothermal pipeline construction

Because the geothermal pipe is the responsibility of the construction personnel, some users invite the construction personnel may not be professionals, in the construction process is not in accordance with the strict standards, it is easy to cause the pipe dead bend (the angle of the bend is too large to cause space extrusion deformation) phenomenon, resulting in the water flow can not flow normally.

4. The geothermal service life is too long, with wax and not cleaned

Every time the geothermal pipe is used, there will be residual microorganisms, vertical bacteria, etc., when the temperature of the water supply pipe changes, calcium and magnesium ion scale will be generated, if it is not cleaned all year round, it will always adhere to the pipe, affecting the water flow.

Geothermal inlet pipe is not hot return pipe thermal solution:

1. When the geothermal water pipe is blocked, close the return valve, then open the exhaust valve on the return pipe, and then close all the valves on the inlet pipe. When the exhaust valve of the return pipe is exhausted, open the inlet pipe valve for exhaust at one time, and the valves are opened one by one during the exhaust process, not all at one time.

2. If the water is not drained clean after the heating is over, you can choose to discharge it yourself. If a large amount of fouling and blockage in the pipeline caused by the filter or other sediment affects the water flow rate, it is necessary to ask a professional to clean it.

3. Due to the dead bend caused by the construction of geothermal pipeline, you can judge whether the water flow resistance is too large by opening the return valve and observing the water flow.

4. For the cleaning of the dirt in the pipeline, it is best for the user not to discharge the sewage by himself, if it is the heating period, it is forbidden to disassemble or discharge the water in the geothermal pipeline without permission, and it is recommended to ask the original installer or cleaning company to clean up the standard.

Summary. The underfloor heating pipe may be too long, or the water supply temperature is too low, and the temperature will be too low when it is circulated back to the water distributor. A hot water circulation pump can be added to the return main to promote the circulation rate of the water.

The underfloor heating pipe may be too long, or the water supply temperature is too low, and the temperature is too low when it is circulated back to the water separator. A hot water loop pump can be added to the return main to promote the circulation of water.

Why is the water cold?

If the length of the floor heating pipe is too large, the greater the length of the floor heating pipe, the greater the system resistance, the corresponding decrease in the water flow velocity, and the time for the water to disperse in the floor heating air digging pipe will be prolonged. It is equivalent to entering within the time of the unit's celebration.

2. The water pressure is not enough, and the flow rate is slow, so you need to compare the water pressure and flow rate with your neighbor Lianglu, and check the opening degree of your own water inlet main valve. 3. The floor heating pipe, sediment sediment sinks and seeps, and the floor heating may be deposited and calcified due to long-term non-use in summer. Find a professional cleanup.

4. There are too few floor heating groups in new houses, and some rough house developers cut corners or design unreasonable water separators, which cause a single group of water pipes to be too long and affect the circulation. Generally, each component of the water separator drives about 14 square meters. Additional Information:

Precautions for the inlet pipe of floor heating: 1. Do not heat up suddenly. In the case of low indoor temperatures, the temperature of the underfloor heating system will suddenly increase.

The underfloor heating element cannot withstand high temperatures for the time being. If there is no slow transition time, not only will the components of the underfloor heating system be damaged, which in turn will affect the service life of the underfloor heating system, but it will also deform the floor. 2. The floor heating pipes should be cleaned regularly to prevent the pipes from being blocked.

During the process of disassembling and assembling the strainer, care must be taken not to have any impurities.
