What is the reason why the floor heating in the house is not hot?

The floor heating of the house is not warm, it may be because the floor heating is not very good, the quality is not very good, resulting in insufficient heating of the house, or it may be related to the wooden floor.

If you are a new house, it is normal for the heating not to be hot for the first year. If your home is warm and other people in the community are normal, you need to find the property for inspection.

The reason why the floor heating of the house is not hot may be the gas in the return pipe, or it may be that the filter screen is too dirty, which affects the circulation of the water inlet pipe and the return pipe, and the heating company can be asked to clean it.

1. Poor quality of heating materials Many manufacturers want to save costs, and there will be some cutting corners or using inferior materials in the production, so that the floor heating after installation is prone to slow heating or the phenomenon that the floor heating is not hot.

2. Improper construction In the installation, some installers do not install in accordance with the corresponding installation method in order to save trouble or covet speed, which will increase the distance between the heating elements of floor heating, which will affect the heat dissipation efficiency of floor heating. Or the floor you choose is too thick, which will also affect its heat dissipation efficiency. If it is caused by improper construction, it is recommended that you should try to choose a professional and experienced installer to install it when installing.

3. The effective heat dissipation area is small Because this heating method is working in the work, the heat is dissipated from the bottom to the top, if the floor is too thick or the ground is piled up too much, it will affect the heat dissipation effect of the floor heating to a certain extent, and the effective heat dissipation area will become smaller, which will lead to us mistakenly thinking that the floor heating is not hot.

4. First use or long-term unused.

The floor heating is not hot, usually there is air in the pipes, or the pipes are blocked by garbage in the water.

You can ask the surrounding neighbors about the situation, if it is not hot, it is the problem of the heating company, it is their lack of heating, if it is only your own home, it may be a problem with the floor heating of your home.

1. It has not been cleaned for a long time.

Pipes can scale during the use of underfloor heating, with an average of 1mm per year, which may seem like a tiny 1mm can cause water temperatures to drop6. Central heating will also cause sludge, bacteria and algae, etc., if not treated regularly, and even cause blockage of floor heating pipelines.

Solution: How to deal with the floor heating that is not hot due to uncleaned? Find a professional cleaning company to clean, generally speaking, the floor heating pipes are cleaned once every 3-5 years, and other equipment must be cleaned before use every year.

2. The construction of floor heating is not standardized.

In the same community, other heating users have good heating effects and shoot every year, while their own heating is not hot, which belongs to the uneven floor heating construction circuit.

Solution: Use the small valve on the water separator to adjust the circulation of each circuit to keep it evenly circulated and achieve the ideal heating effect.

1. The floor heating is not hot, it may be used at the beginning or not used for a long time, there will be a problem that the temperature cannot go up, sometimes the valve is not fully opened, and the water circulation is not particularly good, including if there is a circulating pump if it is stuck, or it is reversed, these will cause the temperature to rise not so fast.

2. In addition, there may be gas in the pipe, which is the same principle as the radiator, if there is gas on the top, it will hinder the water circulation, so it will lead to poor heating effect.

3. In addition, it is necessary to consider whether it is the problem of clogging of the sparrow ear in the filter device, and check whether there is any blockage, so as to lead to the normal circulation of water.

4. Another reason is that if the floor heating pipe is not cleaned for a long time, a lot of scale or some silt accumulates in the pipe, which will directly lead to blockage.

Effect. Common causes and solutions of floor heating not heating:

1. First use or long-term unused.

Reasons why floor heating is not hot: When the floor heating is used for the first time or not used for a long time, the water temperature is low, the heating is slow, and the outside temperature is low, and it may take more than ten hours to reach the ideal temperature. Heating up for too long leads consumers to mistakenly think that it is a problem with floor heating.

Solution: This is not a problem of the quality of the floor heating itself, as long as you wait patiently for the temperature to rise during the initial heating.

2. The effective heat dissipation area is small.

Reasons why floor heating is not hot: The heat generated by floor heating is conducted from the bottom up, and if the ground covers a lot and occupies most of the room area, it will affect the heat dissipation. The effective heat dissipation area is small, and it is easy to mistake people for that the floor heating is not hot.

Solution: This is not a quality problem of the floor heating itself, as long as you wait patiently for the temperature to rise during the initial heating.

3. There is gas in the pipeline.

Reasons why the floor heating is not hot: If the main floor heating pipe is hot and the return pipe is not hot, it means that there is gas in the pipe, which causes the hot water to not enter the circuit circulation.

Solution: Open the air release valve on the water separator to vent until hot water is released.

4. The filter is blocked.

Reason why the floor heating is not hot: If the water supply main is not hot, it may be because the cress is too slippery and the rubber is too poor, which causes the filter to be blocked, which affects the normal circulation of the system.

Solution: Use a wrench to open the filter, clean the filter inside, and then install it back. If you are afraid that you will damage the filter by improper operation, you can also find a professional to clean it.

Floor heating is not hot, and there are generally these situations

1. The filter screen outside the floor heating is blocked, and there is a filter screen in the bottom protruding position, there are dirty things, which will be filtered into the inside, and will not enter the floor heating pipeline, this position is the easiest to block, if the blockage is not smooth, it will cause bad circulation, the water inlet pipe is hot, and the return pipe is too cold. Generally, you can clean it up, and this one needs to be cleaned up by the heat.

2. Another is that there is gas in the floor heating, and after there is gas, it will also cause bad circulation and cause no heat, so you can make a small pipe to put down the water and gas inside.

The floor heating main pipe is hot, and the return pipe is not hot, that is, there is air in the pipe, resulting in hot water cannot enter the circuit and cannot be circulated.

Solution: Close the return valve first, and then manually open the exhaust valve of the floor heating for exhaust, close each valve on the inlet water first, and then open the exhaust all the way. There may be water overflow during the exhaust process, you can find a small basin to connect the water, wait for the air in the floor heating pipeline to be completely drained and heated for half an hour to see the effect, many times the return pipe is not hot is also related to the exhaust.

<> underfloor heating is not heating because the pressure in the pipes is not enough, there is air in the underfloor heating pipes, or because the filters are clogged. 1. The pressure of the pipeline is not enough, if the floor is relatively high or at the end of the district heating, the pressure of the pipeline may not be enough, resulting in insufficient heating. At this time, a circulating pump can be installed to increase the circulation speed of hot water, so as to achieve the ideal heating effect.

2. There is gas in the pipeline, resulting in hot water can not enter the circuit circulation, at this time, you can open the air release valve on the water separator for gassing, and wait until there is hot water released and then close. 3. The filter is blocked, if the water quality of the heating is not good, it will make the impurities carried clog the filter, so that the hot water can not circulate normally, then stop it first, open the filter with a wrench, remove the filter and clean it and reinstall it.

Causes and Methods:

1. The water pipe is in direct contact with the back of the floor, the contact point is too small, the heat conduction effect is poor, and the temperature cannot be raised.

Solution: On this basis, a thickness of not less than 30mm of bean stone concrete should be laid to expand the contact surface between the floor and the pipeline.

2. Heating will lead to a decrease in the humidity of the room, and after being reduced to a certain range, it will cause the deabsorption and contraction of wood products, cracking and other irreversible conditions.

Solution: Keep the humidity of the room between 40-60% and the surface temperature of the floor not exceeding 27 degrees.

3. The floor heating filter is blocked.

If the main water supply bar is not hot, it may be because the water quality is too poor or too dirty, so that the filter is clogged, which affects the normal circulation of the system.

Solution: Close the water supply valve and return valve first, then open the filter to clean the filter inside, and finally install it back. If the operation is not good and you are afraid of damaging the filter, you can find a professional to clean it.

4. The floor is too high and the pipeline pressure is not enough.

The floor is too high or at the end of the water supply in the community, the pressure in the pipeline is not large enough, and the speed of the water flow will be directly reduced, which will lead to insufficient hot water in the pipeline.

Solution: You can first find the property and heating company to solve the problem, if you can't solve it, you can consider buying a circulating pump to improve the circulation of hot water, which will generally be improved.

5. The circuit is uneven.

If it is in the same district, the heating effect of other users is very good, but their own effect is very poor, which may be the uneven floor heating construction circuit.

Solution: Use the small valve on the water separator to mediate the circulation of each circuit, so that it can circulate evenly and achieve a good heating effect.

What to do if the geothermal heat is not hot.

1. As long as the temperature rises during the initial heating process, it is not a quality problem of the floor heating itself.

2. Open the drain valve on the water separator until hot water is released.

3. Open the filter with an adjustable wrench, clean the inner filter, and then reinstall it. If you're afraid of damaging the filter incorrectly, you can also find a professional to clean it.

Fourth, find a real estate or heating company to solve. If it can't be solved, a circulating ruler bend pump can be installed to improve the circulation of hot water and achieve the desired effect.

5. If the floor heating is not hot due to uneven circuits, please use the small valve on the water separator to adjust the circulation of each circuit to make it circulate evenly to achieve the ideal heating effect. However, improper underfloor heating construction due to improper construction is more troublesome. Consumers are advised to check the relevant qualifications and model items when selecting a geothermal system, and to supervise the site during installation.

Why geothermal heat is not hot.

1. The first use or long-term non-use will cause the geothermal heat to not be hot. When using floor heating for the first time or not using it for a long time, the water temperature is low, the heating temperature is slow, and the outside temperature is low, and it may take more than ten hours to reach the ideal temperature. Heating for too long can cause consumers to mistakenly believe that it is a problem with underfloor heating.

Second, the effective heat dissipation area is small, and the regret quietly causes the ground heat to not heat. Floor heating is carried out from the bottom to the top of the mausoleum. If the floor covers a large area and takes up most of the room area, this will affect the heat dissipation.

The effective heat dissipation area is small, and it is easy to make people feel that the floor is warm but not hot.

3. There is gas in the pipeline, which causes the geothermal heat to not be hot. If the underfloor heating is hot and the return pipe is not hot, it means that there is gas in the pipes, causing hot water to enter the circuit circulation.

Fourth, the pipeline pressure is not enough, resulting in geothermal heat. Once the floor is too high, or it is located at the end of the heating of the cell, the pressure of the pipe is not high, resulting in unsatisfactory heating effect.

Fifth, the geothermal heat is not hot due to long-term non-cleaning. Pipes will scale during underfloor heating, with an average annual scale of 1mm. This seems to be a slight 1 mm, which can cause the water temperature to drop by 6°C.

District heating can also cause sludge, algae, etc., and can even cause clogging of underfloor heating pipes if not treated regularly.
