How to solve the problem that the floor heating inlet and return water are not hot, and the floor he

Agree with the opinion of the eternal S-jun, first check whether the pipes and valves are unobstructed, and if there is no problem, let it go for a while. Floor heating is not hot, except for the physical blockage is the air blockage, there is no other problem.

If the pipe is not leaking and the valve is not necrotic, it is deflated, which may be suffocated.

Take a look at the deflating and inspect the pipes to see if there are any blockages.

Open the valve of the heating head and deflate it to see if the valve is open.

Hello, dear to the question you asked, here are the following answers for you: 1. What to do if the geothermal inlet pipe and return pipe are not hot, the geothermal water inlet pipe and return pipe are not hot may be because the pipeline is blocked, in this case, the return valve of the geothermal should be closed, and the exhaust valve should be opened, and then opened one by one after closing the valves for exhaust, it may also be because the water in the geothermal pipe is not released after the end of the heating period, resulting in scaling in the pipeline, in this case, the geothermal water inlet pipe and return pipe need to be cleaned and maintained. 2. Precautions for the use of geothermal 1, when using geothermal for the first time, it is necessary to pass in water with a temperature between 25 and 30 degrees, and then open the valve of the return pipe and water supply pipe, and then adjust the temperature of the geothermal heat by 5 to 10 degrees after running for about seven days, and after the water supply temperature reaches 60 to 65 degrees, the geothermal energy can operate normally.

2. Although the geothermal system should be inspected during the acceptance of the house, there may be man-made damage in the process of house decoration, which will affect the normal operation of the geothermal system. 2. When using geothermal energy, the system temperature should not be set too high, because the indoor temperature is relatively low, if the geothermal heat rises suddenly, the geothermal element can not withstand too high temperature, which will cause damage to the components of the geothermal system, thereby shortening the service life of geothermal energy. Thank you for your patience

Summary. Hello dear, I'm glad to answer your <>, the floor heating inlet and return water are not hot 1, there is a gas blockage in the floor heating water pipe 2, the heating period is not all the water released 3, the floor heating construction problem 4, the floor heating pipe is not cleared all year round.

The floor heating is not hot when the water enters and the water is not hot.

Wait. Hello dear, I'm glad to answer your <>, the floor heating inlet and return water are not hot 1, there is a gas blockage in the floor heating water pipe 2, the heating period is not all the water released 3, the floor heating construction problem 4, the floor heating pipe is not cleared all year round.

Hello dear, if the floor heating is not solved after cleaning and degassing, in view of this situation, the return water pressure is small, it is recommended to install a circulating pump to solve the problem.

Hello, expand the content, floor heating installation precautions 1, be sure to find a construction team with professional knowledge of floor heating 2, must check the floor heating system before paving, the sealed ground must be dry, the moisture content of the cement floor should be lower than zui; The indoor humidity should not be too large, regardless of whether there is geothermal heating, the ambient humidity is about 60 degrees before and after installation.

<> it is not normal for the floor heating inlet water to heat and the return water is not hot. The reasons why the backwater is not hot are as follows: 1. There is an air blockage in the floor heating 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 floor heating pipe network. Otherwise, long-term fouling will cause a decrease in flow, poor flow flow, and reduced heat conduction efficiency, resulting in pipe network blockage. 3. Floor heating construction defects.

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 floor heating pipe has not been cleaned all year round.

After the use of the floor heating pipe, there will be biological slime and impurities, bacteria generated, and then due to the change of water supply temperature, calcium and magnesium ion scale will be 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. 5. The valve of the return pipe is not opened.

Reasons why the inlet water of floor heating is not hot and the return water is not hot:

1. The return valve is not fully opened.

Solution: Check whether the return valve is fully open ("one" is open, "ten" is closed).

2. It is caused by the presence of air in the floor heating pipes.

The main reason why the water supply is hot but the return water is not hot is that there is air in the pipe, which makes it impossible for hot water to flow into the circuit for circulation.

Solution: First of all, you need to find the air release valve on the water supply and return pipe, and then unscrew the air in order until there is hot water discharge.

3. The floor heating filter is blocked.

The underfloor heating filter is mainly based on the "Y type" and is installed on the water separator of the inlet pipe. When the filter is blocked, only a small amount of water flows through the filter, resulting in hot inlet water and no hot return water.

Solution: First, remove and remove the filter, then clean the dirt in the filter, and rinse the filter with clean water, or use an old toothbrush. After cleaning, you also need to check whether the filter will still clog until you are sure that it is rinsed, and then put it back on as it is.

4. The floor heating pipe is blocked.

If the floor heating equipment is not cleaned for a long time, it will also cause a large amount of scale, bacteria and other impurities in the pipes. This is also one of the main reasons why the inlet pipe is hot, and the return pipe is not hot.

Solution: Normally, the floor heating pipes should be cleaned every two to three years or so, and the cleaning of the floor heating pipes must be carried out by a professional company. If this problem occurs in the newly installed underfloor heating, it is mainly due to a mistake in the installation, and it should be repaired immediately.

Attention should be paid to the use of underfloor heating

1. The surface temperature should not be too high.

When using floor heating equipment, there is a special point to pay attention to, that is, the surface temperature can not exceed 28 degrees, and the temperature of the water pipe can not exceed 45 degrees, because if it exceeds this temperature, it will have a great impact on the service life of the floor.

2. Turn off the geothermal system and pay attention to the gradual cooling.

After the winter passes, the weather continues to warm up, the temperature will continue to increase, this time there is no longer a need for geothermal heating system, this time there is a special need to pay attention to the fact that there is a gradual process of turning off the floor heating, can not be suddenly cooled, so that the floor will also affect the service life of the floor.

3. When the room is too dry, humidification needs to be considered.

We all know that the climate in winter is very dry, coupled with the use of floor heating, the floor is in a high temperature state for a long time, and it may be more prone to dry cracking, so at this time, the room should be properly humidified to avoid the floor from drying out or deforming.

The reason why the inlet water of the floor heating is hot and the water is cooled is because there is air resistance inside the floor heating, which causes the water to not circulate and cannot achieve the purpose of heat exchange.

1. There is air resistance inside.

Pipeline maintenance will cause some gas to enter the pipeline, and the water also contains gas, which accumulates into the system, forming a gas blockage, affecting the normal circulation and flow of hot water, resulting in problems such as individual radiators in the room not being hot or neighbors heating their own homes.

2. Water is not circulating.

If the heating pipe is too long, the circulation speed of the water will be significantly slowed down if the pipe is too long, just like there is no circulation, or the water pressure in the heating is not enough, you can install a circulating pump to solve the problem, the circulating pump can effectively increase the pressure in the heating, the switch of the inlet and outlet pipes is not fully opened, if it is not fully opened, the water flow of the heating will be reduced, and the heating water will not circulate.

3. Heat exchange.

The working principle of the heating heat exchanger is the same as the working principle of the water cooling system, that is, the heat exchange of two liquids in a double-layer container, and the heat part of the heating or hot water provided by the heating company is transferred to the water on the other side, which is used for bathing or as domestic hot water, etc.

Underfloor heating

Floor heating is the abbreviation of floor radiant heating, which uses the whole ground as a radiator, through the heat medium in the floor radiation layer, evenly heats the entire ground, and heats the room through the ground in the way of radiation and convection heat transfer, so as to achieve the purpose of comfortable heating. According to different heat transfer media, it is divided into two categories: water floor heating and electric floor heating, and according to different pavement structures, it is mainly divided into dry floor heating and wet floor heating.

01 The reasons why the inlet and return water of the floor heating is not hot are as follows: 1. There is a gas blockage in the floor heating water pipe. 2. The water is not released at the end of the heating period. 3. Floor heating construction problems. 4. The floor heating pipe has not been cleaned all year round.

Many families in the north have begun to use floor heating, heating and air conditioning, and some owners may feel that the floor heating of the family is hot but the backwater is not hot, and the indoor temperature cannot go up, which makes many people not know what is going on.

The reasons are as follows: 1. There is a gas blockage in the floor heating water pipe.

It may be that there is a gas blockage in the floor heating pipe, that is, the air enters the floor heating pipe, which is blocked, resulting in the water not flowing. To close the return valve first, and then put the return pipe.

The exhaust valve on the port is opened, and each valve on the inlet pipe is closed first, and then the exhaust is opened one by one. After the gas is emptied, open the valve normally, listen to the sound of water flowing, and observe whether the return pipe is hot for a while.

2. The water is not released at the end of the heating period.

Long-term deposition and fouling of water in the water pipe will cause a decrease in water flow, poor flow of water, and heat conduction.

Reduced efficiency. After the end of the heating period each year, all the water in the floor heating pipe should be discharged.

3. Floor heating construction problems.

If the construction personnel do not construct the floor heating coil carefully, the pipeline may appear dead bends and flattened, resulting in poor water flow and increased resistance, and it is also possible that the spacing of the pipes does not meet the design requirements.

4. The floor heating pipe has not been cleaned all year round.

If the heating effect of floor heating was normal in the past, it was only this year that the floor heating was not hot. This may be due to the fact that the floor heating water pipes will produce impurities and scale after being used for a long time. After several years of long-term attachment to the inner wall of the water pipeline, if it is not cleaned and maintained in time, it will cause the inner diameter of the floor heating pipe to gradually narrow, and the water flow will become smaller and smaller, which directly affects the heating effect.

In this way, it is necessary to find a floor heating cleaning company to clean the floor heating water pipes.

The reason why the floor heating water is not hot and the return water is that there is air blockage in the floor heating pipe, sediment in the floor heating pipe, and floor heating construction problems.

1. There is air blockage in the floor heating pipe.

There is a gas blockage in the heating pipe, that is, the air enters the geothermal pipe, which is blocked, causing the water to not flow. 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.

2. There is sediment in the floor heating pipe.

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 pipeline will gradually shrink and the water volume 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 siltation will occur, and the sediment in the pipe needs to be removed.

3. Floor heating construction problems.

When using the floor heating coil, due to the lack of attention of the construction personnel, the pipe will be dead bend, pressure leveling, resulting in unsmooth water flow and increased resistance. It is also possible that the distance of the drain pipe does not match the design. We can't see this from the outside, if the floor heating was normal before, but now the return pipe is not hot, then it is not a problem.

Is it normal for geothermal water to be hot and return to cool water?

Abnormal, this is a typical sign of poor supply and return water circulation. The main reasons are these four points: the first is to hold air in the pipeline, and the pipeline needs to be exhausted at this time; The second is that the filter is blocked, and the next thing you need to clean the filter is; The third is that the pipeline is blocked, and the way of draining the ground coil pipe is used to flush it; The fourth is that the pressure difference between the supply and return of water is too small, and the relevant departments should be found to solve it.
