What should I do if the floor heating is not hot What should I do if the floor heating is not hot ?

Causes and solutions for not heating underfloor heating:

1. Not enough pressure.

Problem phenomenon: Some households have too high floors or the heating end of the community is not enough, and the pipe pressure is not enough, resulting in unsatisfactory heating.

Solution: In this case, you need to find a heating company or property to solve, if you can't solve it, it is recommended to install a circulating pump to improve the circulation of hot water to achieve the ideal heating effect.

2. There is gas in the pipeline.

Problem phenomenon: the main bar of floor heating is hot, and the return bar is not hot, because there is gas in the pipe, which causes hot water to not enter the circuit and cannot be circulated.

Solution: Use the air release valve on the water separator to open the air in the pipe, and deflate until the hot water is released.

3. The circuit is uneven.

Problem phenomenon: other users in the same community have good heating effect, but their own effect is not good, and the floor heating construction circuit is uneven.

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

4. The filter is blocked.

Problem phenomenon: The main water supply bar is not hot, it may be that the heating water quality is too dirty, resulting in the filter blockage, which cannot make it circulate normally.

Solution: Use a wrench to open the filter, clean the filter inside, and install it back from the new one, or you can find a professional person to clean it.

5. The floor heating is not cleaned for a long time.

Other phenomena: the maintenance of floor heating equipment is not timely, and the floor heating is not hot due to inadequacy. In underfloor heating systems, the average annual pipe fouling is 1 mm, and this 1 mm thick scale can cause the water temperature to drop6.

In addition, the floor heating system mainly adopts a specially designed pipeline circuit structure, the shape is complex, the pipeline is long, the change of water supply temperature will produce calcium and magnesium ion scale, and the central heating will also have silt rust scale, bacteria and algae, etc., such as irregular treatment, long-term attachment to the inner wall of the pipeline, will reduce the temperature of the floor heating system, failure, and even cause embolism of the floor heating pipeline.

Generally speaking, the floor heating pipe is cleaned once every 3 to 5 years, and the floor heating equipment needs to be cleaned before the annual floor heating supply, and the floor heating cleaning should be completed by a professional floor heating cleaning company.

Let's find someone from the heating company to take a look.

<><How to deal with underfloor heating if it is not hot

It is inevitable that there will be such and such problems in the use of floor heating, if the floor heating is not hot, it must be solved in time, otherwise it will make the family freeze.

1. What should I do if the floor heating is not hot due to gas in the pipe?

Floor heating is not hot performance: the main bar of floor heating is hot, and the return bar is not hot, because there is air in the pipe, which causes hot water to not enter the circuit and cannot be circulated.

Floor heating is not hot solution: use the air release valve on the water distributor to open the air in the pipe, and deflate until the hot water is released.

2. What should I do if the floor heating is not hot due to insufficient pipeline pressure?

Underfloor heating is not hot: the floor where the user lives is too high or at the end of the heating in the residential area, and the pipe pressure is not enough, resulting in insufficient heating.

Floor heating is not hot solution: in this case, you need to find a heating company or find a property to solve, if it can't be solved, it is recommended to install a circulating pump to improve the circulation of hot water to achieve the ideal heating effect.

3. What should I do if the floor heating is not hot due to filter blockage

Floor heating is not hot: the main water supply bar is not hot, it may be that the heating water quality is too dirty, resulting in the filter blockage, which can not make it circulate normally.

The solution to the floor heating is not hot: use a wrench to open the filter, clean the filter inside before destroying, and install it back from the new, or you can find professional personnel to clean it.

4. What should I do if the floor heating is not hot due to uneven circuits?

Floor heating is not hot performance: other users in the same community have good heating effect, but their own effect is not good, and the floor heating construction circuit is uneven.

Floor heating is not hot solution: use the small valve on the water separator to mediate the circulation of each circuit, so that it can circulate evenly, so as to achieve the ideal heating effect.

1. The overall floor heating effect is not good.

In this case, it is necessary to consider whether the floor heating pipe and wall-hung boiler have been maintained in time. The normal maintenance frequency of floor heating is once in two heating seasons, if it is not maintained for a long time, the pipe is easy to produce a variety of dirt attached to the pipe wall, which will affect the heating effect. The same is true for wall-hung boilers, which will cause fouling inside the machine during long-term use, and impurities will block the gas holes, or adsorb on the heat exchanger, which will not only directly affect the heating effect, but also reduce the service life of the wall-hung boiler.

If there is damage to the inside of the wall-hung boiler, the underfloor heating system will not do anything.

2. Some rooms are not hot.

If it is the first time to heat supply, you can first check whether the flow control valve of the manifold in the corresponding room is open, if it is not opened, the corresponding room will not be hot. If the valves are all open, then it may be that the circuit gap is too large, and the resistance of the long circuit is large, resulting in no hot water entering the circulation in this part of the area, or the circulation speed is slow.

At this time, there are two solutions, one is to install a circulating pump to increase the flow rate and increase the flow rate; The second is to install radiators to increase the area of heat dissipation terminals.

3. The floor heating inlet and return pipes are hot, but the room is not hot.

If all the switches are turned on, then you can check for air blockages in the pipes, which will prevent hot water from entering the waterway and the room will not be hot.

The solution is to close the return valve first, then open the exhaust valve on the manifold 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 catch the water, and wait for the air in the floor heating pipeline to be completely drained and heated for half an hour to see the effect.

1. If the floor heating at home 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 there will be more than 10 hours to reach the ideal temperature. Solution: This is not actually a quality problem of the floor heating itself, as long as you wait patiently for the temperature to rise during the initial heating, but now the general heating room temperature is 18.

2. The heat generated by floor heating is conducted from the bottom to the top, if there are more items on the ground, it will affect the heat dissipation effect, and if the effective heat dissipation area is small, it will easily lead to mistaken thinking that the ground is not hot. Solution: Clean up the ground in the home, lay less carpets, and use legged furniture, which will also warm up the floor heating in the home.

If the main pipe in the home is hot and the return pipe is not hot, it means that there is gas in the pipe, which prevents the hot water from entering the circuit circulation. Solution: Turn on the water dispenser at home and drain the air from the pipe until the hot water is released.

3. If the heating pipe is not hot, it is mainly because the water quality is too poor and the filter is blocked, which affects the normal circulation of the system. Solution: If you have a wrench at home, 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, although it costs some money, but you can save yourself.

4. Scaling will occur in the pipeline during the use of floor heating, with an average annual scale of 1, which may seem to be a small 1 will cause the water temperature to drop 6. If it is central heating, there will be silt, grinding bacteria and algae, etc., if not treated regularly, it will even cause blockage of the floor heating pipeline. Workaround:

Cleaning floor heating is a time-consuming job, be sure to find a professional cleaning company to clean, generally speaking, floor heating pipes are cleaned once every 3-5 years, if the water quality is poor, it should be cleaned in a short time, and other equipment should be cleaned before use every year.

Floor heating is a very comfortable heating method at present, many owners will decorate the floor heating when decorating the house, let's see what to do if the floor heating is not hot, and the treatment of the floor heating is not hot.

How to deal with underfloor heating if it is not hot

First-time use or long-term inactivity.

Reason: 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 with the quality of the floor heating itself, as long as you wait patiently for the temperature to rise during the initial heating.

The pressure in the pipes is not enough.

Reason: The floor is too high, or it is located at the end of the community heating, and the pipe pressure is not high, resulting in unsatisfactory heating effect.

Solution: Find the property or heating company to solve, if it can't be solved, you can install a loop pump to improve the loop of hot water to achieve the desired effect.

Reason: Some irresponsible construction personnel do not follow the drawings when installing floor heating, expand the spacing of the pipe at will, uneven circuit during construction, and even appear coil dead bend, resulting in poor water circulation, resulting in unheated floor heating.

Solution: If the floor heating is not hot due to uneven circuits, a small valve on the water separator can be used to adjust the circulation of each circuit to make it evenly return to achieve the ideal heating effect. However, it is more troublesome to solve the problem of not heating the floor heating caused by other improper construction, and it is recommended that consumers should check the relevant qualifications and model projects when choosing an engineering company, and they should also supervise the installation process on site.

There is gas in the pipes.

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

The solution to the problem is to open the air release valve on the water separator and exhaust until the hot water is released.

The effective heat dissipation area is small.

Reason: The heat generated by underfloor heating is conducted from the bottom up, and if the floor is covered and takes up most of the room, 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: Try to use furniture with legs, and do not lay large areas of carpet indoors.

The screening program is clogged.

Reason: If the main water supply bar is not hot, it may be because the water quality is too poor, which leads to the blockage of the screening program, which affects the normal circulation of the system. Workaround:

Use a wrench to open the screening program, clean the filter inside, and then install it back. If you are afraid that you will damage the screening program if you do not operate properly, you can also find a professional to clean it.

It has not been cleaned for a long time.

Cause: Pipes scale during the use of underfloor heating, with an average of 1mm per year, which may seem like a tiny 1mm can cause water temperature drops6. Central heating will also cause sludge, bacteria and algae, etc., if not treated regularly, it will even cause embolism of floor heating pipelines.

Solution: Find a professional cleaning company to clean, generally speaking, the floor heating pipe is cleaned once every 3-5 years, and other equipment must be cleaned before use every year.

The above is the relevant introduction of this article, I believe that you have a simple understanding of this after reading it, if necessary, you can continue to Guanling Fraud Note No. 1 Home Network, to learn more information.

The design temperature of the supply and return water of the ground heating in most areas is 55 and 45, that is to say, the temperature of the water supply is 55, the temperature of the return water is 45, and there is a temperature difference of 10 degrees between the water supply and the return water; If the design is okay, let's talk about the next construction. In the case of construction and installation drawings, as long as the technology is passed, there will be no problems. However, the actual situation shows that the situation that the floor heating is not hot due to construction reasons still exists, and the reasons are as follows:

The water collector of floor heating is composed of a water divider and a water collector, the water divider and the water collector are actually two different things with different division of labor, the water divider is a water distribution device that connects the heating water pipes, and the water collector is a water collection device that connects the heating pipes.

<> If the inlet water temperature of your home is high and the outlet temperature is low, the general outlet water temperature is 10 degrees lower than the inlet water, if it is lower than 10 degrees, it is likely that the floor heating is blocked, resulting in a slow flow rate, the outlet water temperature is reduced, or the filter screen of the water separator is blocked, and it needs to be cleaned. Most basically, you should check that all valves are not fully open! There is an exhaust point at the position of the water separator, unscrew it to see if the air is drained clean!

Then check the pipe strainer, unscrew it with a wrench, and clean it! If that's all right! It's time to clean the pipes!

The inlet water temperature of floor heating is about 40-55 degrees, which varies depending on the temperature change, and the weather is cold, and the inlet water temperature should be increased. Burn it yourself, you can raise the temperature. If you are collectively heating, find a heating company or a heat exchange station, and it is best to pass ****.

You can use a thermometer to test the temperature of the main entrance to the house, to see whether the temperature and pressure of the water inlet of the floor heating water separator is normal, the general water temperature needs to be above 40, if the water temperature is too low, you must contact the property or heating company to solve the problem, to ensure that the water temperature meets the requirements, otherwise the house will not be too warm. First of all, it is clear whether the water can be circulated in the floor heating pipe, whether the flow rate is enough, whether the supply back pressure difference can reach kilograms, whether the water temperature can reach the standard, whether there is a thermal insulation board during the floor heating construction, and then whether the density and single length of the tube meet the specifications.

It is because there will be some problems at the beginning of use, and it cannot be quickly transmitted, and there may be no water, so that there is no way to implement and apply floor heating, and professional personnel should be found to solve it.
