Does the thickness of the floor have anything to do with whether the return water is not hot?

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.

The solution to the geothermal return pipe is not hot.

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.

Basically, it doesn't matter, at the beginning of the ground cool back water will be cooler, but after a period of time, the return water temperature will be stable, in addition, the difference between the temperature and the water temperature of about 10 degrees should be considered normal, if it is lower than this number may be the heating flow rate is not enough, you need to look at the water temperature at the same time, if not, find heating maintenance, and if the water is very hot, you can be waterproof.

It doesn't matter, whether the floor heating is hot or not lies in the heating pipe water supply circulation, the less the circulation is cold, the floor is higher, and the water is cold if it does not go.

It doesn't matter, the floor is thick, the backwater should be hotter.

Reasons why the floor is not hot:

1. The geothermal pipe is not cleaned

The first reason why the floor heat is not hot is that the floor heating pipes are not cleaned and the scale is accumulated. Floor heating equipment is used for a long time, the combination of calcium and magnesium ions in the floor heating pipe will form scale, impurities, etc., the thermal conductivity of scale is extremely poor, in the heat exchange process, the scale increases from 0mm to 0 3mm, and the heat exchange rate will be reduced to 79.

2. There is air in the geothermal pipe

If the main floor heating bar is hot and the return bar is not hot, it may be that the air in the floor heating pipe causes air resistance, resulting in hot water not being able to enter the circuit and cannot be circulated. In this case we need to check that the return valve is open.

3. The pipeline pressure is not enough

If the floor of the home is too high, or it is located at the end of the community heating, the pressure of the pipe is not enough, resulting in poor heating effect. You can ask the property or heating company to help you solve the problem, and if they can't solve the problem, then install a circulating pump to improve the hot water circulation to achieve the ideal heating effect.

Notes:

1. During the operation of the floor heating system, the filters, valves, thermometers, pressure gauges, etc. should be checked regularly to see if they can be used normally. In view of the creep characteristics of the pipe affected by temperature and pressure, during the heating period, there should be a special person to tighten the water collector and the valves and connectors at the front end many times, and regularly clean the impurities in the filter.

2. Before running the water and floor heating system for the first time, the pipeline system should be tested to see if there is any leakage, water leakage and electricity leakage.

First, is it possible that the floor heating is partially blocked (lived for 10 years), resulting in the inlet and return water are hot and the home is not hot? If so, how to judge and solve.

Second, is it possible that the pressure on the top floor is not enough, resulting in poor circulation (I personally feel that the pressure is okay when the water is released, and there is not much pressure in each tube)? If so, how to judge and solve.

Third, is it possible that the unreasonable layout of the pipeline during the construction (but other residents did not have such a situation)? If so, how to judge and solve.

Fourth, the valves and water separators in each link have been replaced with new ones before heating this year, and the factors that are not smooth in these links should be ruled out.

Fifth, the floor tiles are paved in line with the specifications: a total of 6cm thick. It should also not be the cause of not being hot.

2.My house is 3 bedrooms and 2 living rooms on the east side, only the floor of the bedroom in the middle feels a little hot, and the other rooms can hardly feel the heat of the floor (that is, no ice hands).

3.The inlet and return water are hot, but they are not hot. The temperature of the water in other households is not as good as my house, but the temperature of other households is 20-25 degrees, and the hottest house in my house is only 17 degrees, and the coldest is 10 degrees.

Because it has been occupied for a long time, if it was hot before, it proves that the pipeline is still reasonable. Also, the filter of the outdoor main pipe has you not cleaned it, if it is. That is, the pipeline time is too long, and the scaling is serious!

It is recommended to find a professional floor heating to clean it! It should work out!

Add a pump to the backwater to speed up the circulation, and you will definitely be able to. The reason why it is not hot is because the water flow is lower as the occupancy rate increases. According to what you have introduced, this is the only way to solve it.

1. The water supply and return pipes are hot, and the first (blocked) and the second (insufficient pressure) can be excluded, because the system is circulating.

2. The valve and water separator are new, and each pipeline has been separately discharged, and impurities have been flushed out, indicating that they are easy to use.

Only ** below is there a problem:

1. It is difficult to say whether the layout of the construction pipeline is reasonable or not, and if the pipeline is short, the backwater may be hotter than others. (Was your house hot in previous years?) ）

2. It may be related to scaling, but everyone has a water source, and you will never be the only one heating scaling?

3. What is the thermal conductivity of floor tiles?

Drain some of the water until the hot water comes out.

1. Copy of laying.

The thermal conductivity of the floor is not good.

If the inlet and return water of the floor heating at home are hot, it may be that the floor tiles are not up to standard, such as too thick, which will also cause the floor to not be easy to heat.

2. Caused by design errors.

If the spacing of the coil design is relatively large and the heat dissipation does not meet the requirements, this situation will appear that the water inlet and return water are also hot, but the floor at home is not hot, if so, there is no good way to solve it, just call a professional to solve it.

3. Cut corners during construction.

The last reason is because the decoration personnel cut corners, and professionals know that some materials of the floor heating system will bury a lot of hidden dangers for the operation of the floor heating system, so not only the decoration process should be paid attention to, but the materials used can not be inferior products such as three no products, there will be potential safety hazards.

The heat of the inlet and outlet water proves that the pipe is fine. Floor heating is relatively slow, it is a plastic pipe to heat the surrounding cement surface, which is much slower than a radiator, and it will heat up after a long time.

This situation is abnormal, generally speaking, the return water temperature is very low, because of the formation of normal heat dissipation, if the water inlet and return water are hot at both ends, it proves that the pipeline is faulty, the water inlet is not effectively dissipated in the pipeline, and the return water is mixed with the water at the return end, which needs to be operated and dealt with by professional plumbers on site.

There is a problem with the construction design of floor heating, and several pipelines are too long and the water resistance is too large. The water has gone through the circuit with little water resistance, so the water in the floor heating is still hot, and it goes to the return pipe. So your return pipe is still hot.

This is the case in the early stage of heating, it takes a process to heat in the house, the temperature of the return water in your home is too low, it proves that the heat is absorbed, the indoor temperature is up, the return water temperature is high, and the temperature difference between the supply and return water is 5-10 degrees under normal times, so now the heat loss is too much. Wait, as long as the filter is not clogged, there is nothing to do.

Hello, I am glad to answer for you that the thermal conductivity of the floor is not good, if the water and return water of the floor heating at home are hot, it may be that the floor tiles are not qualified, such as too thick, which will also cause the floor to not be easy to heat. 2. If the spacing of the coil design is relatively large and the heat dissipation does not meet the requirements, this situation will appear that the water inlet and return water are also hot, but the floor at home is not hot.

Questions. It's been two years, it used to be hot, but this year it's not hot.

If it used to be hot, but now it's not hot, you can find a geothermal one to wash it and see how it works?

Add a pump to the backwater to speed up the circulation, and you will definitely be able to. The reason why it is not hot is because the water flow is lower as the occupancy rate increases. According to what you have introduced, this is the only way to solve it.

Open your eyes and talk nonsense, if it's not hot, where does the hot water come from, unless you wrap the pipe with thermal insulation when you install floor heating, a fool won't do this.

If it is blocked, your backwater will not be hot, and the heating of the floor heating is originally very slow. Hope it helps!

Hello, this is also the case in my family. Did it just close and open again? If you bet on your backwater, it won't be hot, and the heating of floor heating is originally very slow. Hope it helps!
