What should I do if the whole radiator is not hot?

Causes and solutions: This situation generally rarely happens, if there is, it may be that the user's heating pipe valve is not opened, resulting in the radiator hot water can not be circulated. At this time, you only need to contact the property or heating company to open the valve.

1. Exhaust the air from the pipe.

Heating pipes may be left empty in the summer, and a certain amount of air may be stored, resulting in poor circulation. Generally speaking, if the inlet pipe is hot, but the outlet pipe is not, it is usually a circulation problem that is rooted in the presence of air that prevents hot water from entering the loop circulation. In this case, you can open the exhaust valve on the underfloor heating to exhaust the air until the hot water drains normally.

2. Clean the floor heating filter.

Due to the large amount of sediment, rust and other impurities in the pipe, when passing through the filter screen at the entrance of the floor heating, it is intercepted by the filter screen, and the water flow of the filter screen is significantly reduced due to the blockage of foreign matter. The filter can be cleaned before the heating season every year to remove impurities.

3. Clean the pipeline.

Cleaning pipes is a kind of deep cleaning of floor heating, and the cleaning process is complex, requiring professionals to use special pulse cleaning equipment.

All of these answers are in a theoretical sense, and have little practical significance. I'll answer a professional.

In the case of tandem mixing, it is most likely to lead to the phenomenon that the heating in the "middle position" is not hot:

One is deflating. The second is to release water.

The third is dredging. Fourth, if none of the above three methods work, add a valve near the outlet of this group of radiators.

The reason for the lack of heat: that is, after opening the "main valve", the water will be poured into this group of radiators from the "inlet and outlet" of the group of radiators connected in parallel almost at the same time, so that in this group of radiators (generally this group of radiators is a lot of pieces or several groups of parallel connections in series, otherwise this phenomenon will also occur) the negative pressure such as nest wind and nest cold water is formed, so that the hot water of the inlet can not be flushed in, and the hot water of the outlet can not be withdrawn, and the circulation of hot water cannot be formed, and the hot water can only flow away from the straight channel without resistance.

The principle and function of installing a valve is: first drain the water in the radiator, then close the valve, and then open the "total water inlet valve" (the whole process is that the "total outlet valve" should always be closed), and so that the hot water enters the outlet valve from the parallel radiator group, and then opens the small valve, and the hot water rushes out of the outlet at once, forming the circulation of this parallel radiator.

The valve of this outlet only serves the role of "diversion", and then has no other role.

Winter is the heating season, and radiators play an important role in home heating. However, sometimes the radiator is not hot and causes inconvenience to people, causing the room temperature to drop. So, what should you do when you encounter the problem that the radiator is not hot?

First of all, we can check whether the temperature switch of the radiator is normal and see if there is any debris blocking the radiator. Sometimes when we place things, we will accidentally block the heat vent, resulting in the radiator is not hot, then we need to adjust the position to ensure that the heat vent is unblocked.

Secondly, it is possible to check whether the boiler is working properly. If the boiler fails, it may cause the radiator to not heat up, at this time, you can check according to the boiler instruction manual or seek professional help.

It is also important to clean the radiators regularly. Long-term use will cause dirt build-up on the radiator, which will affect the heat dissipation effect and cause the radiator to not be hot. Therefore, the radiator needs to be cleaned before the heating season and kept clean regularly, which can effectively ensure the heat dissipation effect of the radiator.

In short, when the radiator is not hot, we must first check whether the temperature switch is normal, whether the heat vent is unobstructed, whether the boiler is working normally, if all the above methods do not solve the problem, it is recommended to ask a professional to check and maintain the normal heating state.

Radiator valve closed: Check whether the valve on the radiator is closed violently. Some radiator valves are manually turned on and off, and if you or someone else accidentally closes the valve, then the radiator will not heat up. If you find that the valve is closed, you need to open it.

If the radiator is not hot, it is generally caused by the following reasons:

The radiator is not turned on or adjusted improperly: Check that the radiator is turned on, or that the temperature control valve is adjusted to the correct position.

Circulating pump failure: Check whether the circulating pump is faulty or needs to be replaced. If the circulating pump fails, you can contact a professional for repair or replacement.

Lack of water pressure: Check if the water pressure of the radiator is normal, if the water pressure is too low, water should be added. However, it should be noted that when adding water, it should be added gradually to avoid adding too much water pressure at one time.

Clogged pipes: Clogged pipes are also a common problem with radiators not celebrating pure heat. In this case, it can be cleaned with a sharp pipe or other pipe cleaner.

Radiators are affected by air: Check whether the radiators are affected by air and rule out possible air influences, such as placing an air release on top of the radiator.

If none of the above methods can solve the problem, it is recommended to contact a professional for repair and repair.

The radiator is not hot, and there are generally three reasons for this:The first is that the temperature control valve of the radiator is closed, the second is that the radiator is not vented in time, and the third is that there is a foreign object in the middle of the radiator. These three situations need to be investigated one by one.

If the temperature control valve is not opened, you can open the temperature control valve counterclockwise and then observe whether the radiator is hot.

If the radiator is not vented in time, you can dispose of it yourself. First close the heating valve at home, prepare the water basin to facilitate the connection of water, and then use the screw to send the gas release valve, listen carefully to whether there is the sound of gas discharge, and stop twisting if there is.

After the gas is discharged, there will be water flowing out slowly, observe whether the water flow is stable, if it is stable, you can close the release valve, observe whether the radiator becomes hot, if not, repeat the above steps, and slowly the heating will heat up. This is the most common failure symptom and there is no need to panic.

1.Unclog heating pipes.

2.Turn on the heating valve.

3.Open the temperature control valve.

4.Exhaust the gas from the pipeline.

If you still can't solve the problem after trying the above methods, you can contact a professional to solve the problem so as not to make the problem worse.

The first thing you need to do is to find a more professional installer when installing the heating, and give a reasonable heating design according to the situation of your own home, including the number of radiator groups, the diameter and direction of the heating pipes, etc., the connection between the heating pipes and the radiator groups, in addition to the air heating, the rest need to be connected to the pipes when the radiator groups go up and down, or down and down to make the heating hot water flow smoothly, only the hot water circulates and flows to the heating can be hot.

1. The radiators and pipes at home are not hot, this situation may be that the main valve of the heating is closed, the main valve is generally in the inspection well of the unit staircase, we only need to check the supply and return valves, and confirm that they are opened.

2. The heating at home is not hot, but the pipes are a little warm. In this case, in order to prevent the radiator from corroding, the grouped valves of each group of heating are closed before the end of the heating of the previous year, so as to prevent the air from entering the heating and making the heating rust and rot, and then the sub-valves of each group of heating need to be opened.

3. The radiator is half hot and half is not hot, there is a sound of water in the radiator, or the temperature of the radiator is not as high as that of other people's homes. In this case, there is air in the radiator group, and the air valve needs to be opened to release the air until there is water flowing out. The method of deflation, on the upper side of the radiator, the toilet heater is at the top, there is a deflation valve that can be adjusted with a screwdriver, rotate counterclockwise, release the air in the heating, and the heating can become hot, and it needs to be deflated many times according to the situation until it is exhausted.

4. The radiator at home is very hot, but the temperature in the house is not high. This situation may be that the power of the heating is too small, and now the home decoration has replaced the radiator group that was originally designed and calculated, but the quality of the newly installed heating construction personnel is uneven, and the specific situation of your home cannot be fully considered, so it may be possible to install less radiator group in your home, so you need to ask professionals to help and redesign the number of radiator groups.

5. The heating temperature at home is different, some are very hot and some are not. In this case, the main reason is that the flow of hot water in each heating is uneven or the internal resistance distribution is uneven, and the water inlet valve of each radiator needs to be adjusted separately.

6. All the heating in the home is close to the heat of the door, the farther away from the door, the lower the temperature, turn off a group of heating, all the heating will not be hot, this situation is caused by the radiator group in series, you think, if the water temperature of the pipe is 75 degrees, after the first group of heating, it will become 65 degrees, and then enter the second group after the temperature may be reduced to 45 degrees, and then the final temperature will be lower, the radiator will definitely not be hot. In this case, find a heating installer as soon as possible, find him to solve it, and compensate you to modify the pipes.

It may be that the heating temperature of the community is not enough or the heating water pressure is too low, resulting in poor heating circulation in residential buildings, resulting in substandard heating. This depends on the situation of the community heating last year, but you can also call the property consultation, if the heating was normal last year, it may also be a gas blockage. When testing the water, the exhaust port at the end of the heating pipe is not opened, resulting in the gas entering the pipe during the irrigation process, resulting in the heating not being hot, which closes the water outlet of the heating at home, opens the water inlet, and then releases each radiator to the exhaust valve in the order of hot water entering the house.

When all radiators are deflated, open the outlet valve.

If the radiator is used for too long, the scale impurities in the heating pipe will increase, block the pipe, cause the water flow to be poor, and will also cause the heating to not be hot. In this way, the heating that is not hot is removed, and the left and right nozzles are connected to two pipes to open the upstream valve and flush the inlet line. If the water output is large, it means that there is no problem with the inlet pipe.

If the water output is small, the pressure is low, and you should look for blockages inside the upstream pipeline. Open the downstream valve, use the same method, and rinse the build-up if it is present.

1. If the main valve of the radiator heating system is not fully opened, it can be put to the maximum by itself or adjusted to a suitable size by the heating department.

2. If the valves of each group of radiator plates are not opened, they can be opened completely.

3. There is air in the heating radiator system, which hinders the water circulation of the entire heating system, resulting in the radiator not being hot, open the exhaust valve and discharge the air in the radiator sheet.

Fourth, the radiator circulation system is caused by sediment debris blockage, you need to open a plug of the radiator, wash with high-pressure water, wash the sediment inside, if it is not good, you must remove the whole radiator, and clean up the debris in the heating radiator and the pipe.

5. For radiators with water connection mode of lower in and lower out or lower in and out of the water connection mode, due to the wrong connection of the water inlet, the water inlet and return port should be connected to the side with the water retainer. If you don't install a baffle, hot water will directly enter from the next interface and flow out from the next interface, if you don't circulate upward, the upper is not hot, and adding the baffle can solve this problem.

Rubens radiator, the global furniture heating elite, will explain to you what may cause the radiator not to heat and the solution.

First, the problem of radiators.

1.The temperature of the radiator in the whole community is not up to standard, so the reason is that the heating temperature of the heating company is not enough, and you can appeal to the heating unit and refund and so on.

2.Only the radiator in their own home is not hot, so you must find a problem, last year whether the radiator was hot, etc., and check the pipes, valves, temperature control valves, etc., if there is a blockage, find the relevant personnel in time to clean and dredge.

3.Some of the radiators are hot and some are not hot or a group of radiators are half hot and half are not hot, in this case, you can check whether the pipeline valves are all opened, and whether the air is accumulated in the radiators, you can open the valve and the radiator exhaust valve to vent, you can also find a radiator master to test the water pressure in and out, if the difference is too much, it may be that the pipe is reversed or the radiator installation mode is changed.

Second, the problem of the heating office.

1.In order to save heating fuel, some heating units adopt inferior fuels, resulting in low boiler work efficiency and even scaling of pipelines.

2.In order to save electric energy, the pressure of the circulating pump is not high, resulting in insufficient heating pressure in the whole heating system, resulting in the heating is not hot.

3.The employees of the heating unit lack a sense of responsibility, and the heating period is not carried out in accordance with the working standards, which makes the temperature difference of the heating system uninterrupted.

That's a big question. It needs to be described a lot, the radiator is not hot in the whole group, and it is generally not hot. You can take a look at it below.

The radiator is not hot as a whole, the boiler is turned on for a few seconds and an error is reported, the boiler heating water temperature is displayed too high, and the furnace is very loud when it is working, generally there is an air body or water pump locked in the heating system.

Solution: Exhaust the whole system until the air is exhausted and the boiler noise becomes smaller.

2.The radiator is half hot and half not hot, or one side heats very slowly, usually there is air in the radiator.

Solution: Exhaust the radiator, when the gas is discharged, the radiator heating will return to normal.

3.There is a group of radiators that are not hot, generally because the radiators are hydraulically imbalanced, this group of radiators is too large, or the circuit is too long, and the hot water is not easy to push the cold water.

Solution: Turn off other radiators that have been hot, turn on the group of radiators that are not hot alone, and when this group of radiators is hot, turn on the radiators in other rooms to solve the problem.

Note: The premise of the above radiator not hot solution is: the radiator valve has been opened, and the water temperature of the gas wall-hung boiler is set normally, and the radiator is not used for a long time.
