What should I do if the gas of the geothermal return pipe is released and it is not hot, please help

The gas is not cleaned. It is not possible to only use the exhaust valve for deflation.

Clause. First, the deflation should be carried out by geothermal pipes. It cannot be deflated at the same time. When venting one of the heating pipes, the others are turned off.

Clause. 2. When deflating, close the main valve of the outlet pipe. The main valve of the inlet pipe is to be opened (this is my nonsense. ）

Clause. 3. The best way to exhaust geothermal air is not to use the exhaust valve for exhaust, but to have two rows of horizontal water pipes. The upper row is the water inlet pipe water separator.

The lower discharge is the outlet pipe water separator. One end of the lower row is connected to the outlet pipe and outlet valve, and the other end is the "plug". Connect the thick hose, insert it in the toilet, turn on the faucet, and then vent the tube separately for about five minutes.

Six tubes take more than 30 minutes in total. It will be good.

Fourth, if the supply is not good, no heating method will work.

The presence of air in the heating pipes will affect the circulation of water, and in serious cases, it will not be hot at all.

Generally, there are air outlets next to the geothermal temperature control valve, you can try to change to an automatic exhaust, if you are now automatic exhaust, then see if it is blocked for a long time.

If not, then you must remember to put more water after changing the automatic exhaust, put the air in the pipe clean, form an automatic circulation of water flow, and then install the automatic exhaust, then you don't have to always think about deflation in the future.

1. The geothermal pipe is caused by air blockage. See if there is a gas blockage in the pipe, then the water will not flow into the pipe. At this point, the return valve should be closed and then the drain valve should be opened to return water.

2. The water is not discharged at the end of the heating period. At the end of the annual heating period, the user should drain the water from the geothermal network, as any water retention will result in a reduced flow rate and a deterioration of water flow. Moreover, the thermal radiation value of the geothermal heat at this time will decrease, resulting in further blockage of the pipe network.

3. Caused by geothermal construction defects, some people have low quality construction personnel and lack professional ability, resulting in bending of floor heating pipes, which will lead to poor water flow of geothermal pipes and unhot geothermal heat over time. The user closes the main valve of the return water and discharges the water to the return pipe. The return valve needs to be opened and the water needs to start circulating.

Because there is an air blockage in the pipeline, it needs to be deflated.

When the circulating pump is pressurized, the water in the pipe is pressurized by the circulating pump without air bubbles and then runs in circulation: if the circulating water is lost for some reason, there is a large amount of gas in the upper part of the pipe. Since air is less dense than water, the water at the high pressure end is blocked because it cannot hold down the air, so the water in this pipe cannot be circulated, and the heating is of course not hot.

Question: What is the matter with the hot water inlet pipe of my house's floor heating and the water outlet pipe not hot.

When the deflation circulating pump is pressurized, the water in the pipeline is pressurized by the circulating pump without air bubbles and then circulated: if the circulating water is lost for some reason, there will be a large amount of gas in the upper part of the pipe. Since air is less dense than water, the water at the high pressure end is blocked because it cannot hold down the air, so the water in this pipe cannot be circulated, and the heating is of course not hot.

The red one on the top, put it slowly.

Question: I'm deflating now, it's been half an hour, and I don't know if it's right or not, the deflating valve and the magnetic sound.

That's gas.

There is no sound when it is finished.

Question: How long does it take to deflate?

I suggest you find a professional cleaner and clean the radiator, they have that kind of suppressive machine.

When the water supply is smooth, the heating will be hot.

Question: My house is underfloor heating, is the heating hot.

At the very least, you can detect which section of your underfloor heating is.

Now we don't have the tools to deflate, and it's okay to deflate in a few minutes.

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 and has not been cleaned

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

Hope it helps.

Question: This is the current situation in my house, the main valve outside is open, there is hot water, but the water inlet pipe at home is not hot, and it has been exhausted for several hours and there is still no hot water.

Question: Do I clean the pipes in my own home? Or the main pipe outside.

Ask me how to do it if I want to vent it.

Answer: Buy the water pipe first, prepare the pliers or wrench, find the exact position that needs to be deflated, connect the water pipe, and then gently open the valve with pliers, and wrap the surrounding of the valve with the towel prepared before, so as to prevent the water from overflowing when the valve is opened, otherwise the water will flow everywhere, and then, then degas the geothermal heat, when deflating, the main valve of the return water main pipe should be closed, and the water pipe should be placed on the lower degassing valve, take a water pipe to carry out geothermal aeration. If there is no sewage and gas spraying out of the floor heating pipe when observing, and then the geothermal heat is opened, and there is no water discharge in the return pipe and single pipe, it proves that there is no problem with the degassing of the geothermal heat, which also proves that the degassing of the geothermal is the normal operation and construction.

Tengzhou bar After heating, how to properly exhaust the floor heating.

Question: I operate these things normally, and then the water inlet pipe at home is still cold, what will be the problem?

Underfloor heating water supply pipe heat. The return pipe is not hot. This problem is troubled step by step.

You can try it one by one at the manifold. See which return pipe is hot and which isn't. If some circuits are hot and some circuits are not, then you need to check the pipes of the circuits that are not hot.

It can be a bit clogged (but the water flow is small). If none of these circuits are hot. Only water and heat are supplied with water.

There is also Kenneng who has a problem with the water separator. The water separator can be changed. There is also the case of how long the meter of your coil is.

There is no more than 100 meters. The industry standard is within 120 meters. We do home decoration generally designed within 90 meters.

Pipes that are too long can also prevent water from flowing. The only way to do this is to add a pump. The other is whether you have opened the return valve of the main pipe when you turn on the machine.

So is my family. The inlet pipe is hot. The return pipe is not hot. Last year, I found someone to clean it, and it was very hot after washing the house... It's not hot this year.

Was it hot last year, your circuits weren't hot, or just a tube wasn't hot. Isn't your heating bad? Otherwise, you can unload the circuit with a pipe wrench to see if the water is circulating

Summary. Hello, I'm sorry to keep you waiting, this situation is mainly because the water pipe is blocked, first close the return pipe, then open the exhaust valve, close the water pipe valve first, and then open it, so that all the air inside will be discharged, and then open the valve, check whether there is a water flow sound, check whether the return pipe is hot.

Hello, I'm sorry to keep you waiting, this situation is mainly because the water pipe is blocked, first close the return pipe, and then open the exhaust valve, close the water pipe valve first, and then open it, so that the internal air will be discharged, and then open the valve, check whether there is a sound of water flow, check whether the return pipe is hot.

What are the reasons why the floor heating inlet water heat return pipe is not hot 1, the pipe in the floor heating is blocked by gas, once the pipe enters the empty shirt and gas, then there will be a blockage, resulting in the water flow can not flow, so that there will be no heat, first of all, the return valve is closed and then the exhaust valve is opened, so that all the air is discharged until there is a sound of water flow. 2. After the end of heating, the water in it is not all discharged, generally after the heating season, all the wax water in the pipeline must be discharged, if there is water in the pipeline, scale will be formed, resulting in poor water flow, and the heat transfer effect will be low. 3. During the construction of floor heating, if the workers do not have the operation specifications, the pipeline will be bent or flattened, which will make the water flow poor, 4. If the heating is normal in previous years, and suddenly there is no hot situation, it may be because of the use or local for a long time There is scale attached to the pipe closed, resulting in blockage, if it is not cleaned and maintained in time, it will be the inner diameter becomes smaller, the water flow becomes smaller, in such a situation, invite professional people to clean.

Kiss, <>

We're glad to answer your questions! After the geothermal return pipe is exhausted, it is still not hot, and there is an air blockage in the floor heating pipeline: in this case, the return valve is closed first, and then the exhaust valve on the return water is opened, the inlet water valve is closed, and then the exhaust is opened all the way; I didn't release all the water at the end of the heating period:

The scale will cause the flow of water to be poor, causing the old pipe network to be blocked, just remove it; Floor heating construction defects, pipe spacing does not meet the requirements, etc. This situation has to be reconstructed; If only the water valve is opened, but the valve of the return pipe is not opened, it will also cause the hot water to flow without a clear potato method. If the heat source circulation power of the floor heating is insufficient, it may lead to the return water of the floor heating is not hot, because the water needs a certain pressure to circulate in the floor heating pipeline, and if the pressure is not enough, the return water will not be hot.

In this case, it is necessary to find a heating company or find a property to solve the problem, if it cannot be solved, it is recommended to install a circulating pump to improve the circulation of hot water to achieve the ideal heating effect. Hope mine can help you! <>

<> "With the improvement of the economy, many homes have installed underfloor heating. So is it okay to keep releasing water when the geothermal return pipe is not hot? Let's find out.

1. Is it okay to keep releasing water when the geothermal return pipe is not hot?

1. The return pipe is not hot, and it is useless to discharge water all the time. 2. There are many reasons why the return pipe is not hot, such as the return pipe valve is not opened, the return pipe is partially blocked, the circulating power is insufficient, and the slope of the return pipe is insufficient. If the hand resistance rock encounters non-hot backwater, it is necessary to contact the maintenance personnel of the local heating company for investigation.

3. If there is no heat during heating, first exhaust the heating at home. If the problem still cannot be solved after exhaust, then you should contact the local heat exchange station maintenance staff for investigation and treatment.

2. Is there pressure in the geothermal return pipe?

1. Although there are many people who use geothermal heating, many people still don't know whether the geothermal return pipe is under pressure. In fact, the geothermal return pipe is still under pressure, and without pressure, the geothermal energy cannot be used normally. And the pressure of the return pipe is directly higher than the pressure of the inlet pipe.

However, the pressure of the return pipe should also be controlled, too large will also affect the use effect, so the exhaust work should be done regularly during use.

2. I believe that there are many friends who use geothermal heating, but many people do not know whether the geothermal return pipe is under pressure. But in fact, there is a certain pressure in the geothermal recuperation pipe, and it can also be higher than the pressure in the inlet pipe. However, if the pressure of the geothermal return pipe is too high, it will directly affect the effect of geothermal utilization, so the exhaust operation should be carried out regularly.

3. There is pressure in the geothermal return pipe, but if there is high pressure in the geothermal return pipe, it is abnormal. It is very likely that there is air in the underfloor heating pipes, which can cause uneven pressure in the water pipes. Therefore, we must exhaust the air in the geothermal return pipe in order to continue to use the acreage.

There is a drain valve installed on the geothermal return pipe, and the user can directly open the drain valve to discharge water.

The main hunger rock of floor heating refers to the key components:

1. Main equipment: usually there are heat source equipment, heating main pipes, water collectors, temperature control systems, ground structure layers, etc. Large houses are also equipped with heating circulating water pumps (which play a pressurizing role), thermostatic mixing valves (energy-saving and comfortable), etc.

Auxiliary materials and accessories include: insulation board (extruded board or benzene board), reflective film, floor heating nails, steel wire mesh, boundary insulation strip, stainless steel hose, ball valve, elbow, direct, etc.

2. Heat source equipment: as a heat source, to meet the energy demand required for the operation of the whole system of floor heating, the heat source equipment includes wall-hung boiler, air source heat pump, ground source heat pump, solar collector and other equipment. The most common heating wall-hung boiler is a gas-fired wall-hung boiler, which is divided into artificial gas and natural gas according to the type of gas.

With the progress of science and technology and the continuous improvement of the world's comprehensive manufacturing level, more energy-saving and environmentally friendly products have appeared on the market, such as air source heat pumps, ground source heat pumps, solar energy and gas wall-hung boiler linkage devices, etc.

3. Main pipeline: The main pipe is the part connected with the water separator in the main pipeline, and the main pipe generally uses aluminum-plastic composite pipe, which needs to be insulated, because this pipeline often increases the heat loss in the process due to heat dissipation, which is easy to oxidize the pipeline; In a smaller underfloor heating system, the amount of mains used is very small, and the direction is simple.

However, in the villa or duplex these relatively large floor heating systems, the supervisor uses a lot of dosage, and a professional designer is needed to design the direction of the supervisor, and the installation requirements of the supervisor are also relatively strict, to be horizontal and vertical.

4. Water manifold: including water collection main pipes, exhaust and drainage devices, branch valves and connecting accessories. It is equivalent to the heart of the floor heating system, the hot water of the whole floor heating system is evenly distributed to each branch by the manifold, and is gathered together after circulating in the floor heating pipe, and then distributed under the action of the pump to ensure the safety and normal operation of the entire heating system.

Note: Water floor heating refers to a heating method that heats water to a certain temperature and transports it to the water pipe cooling network under the floor, and realizes the purpose of heating through floor heating.

It is divided into two categories: water floor heating and electric floor heating from the thermal medium quality, and is divided into wet floor heating and dry floor heating from the pavement structure. From the surface decoration material, it is divided into floor type floor heating and floor tile type floor heating; Functionally, it is divided into ordinary floor heating and far-infrared floor heating.
