What is the reason why some radiators are not hot, and what are the specific reasons?

There are many situations in which the radiator part is not hot, the main ones are:

1. One set of heating is not hot.

There can be two reasons for this:

1) The resistance of each heating is uneven, resulting in uneven water flow, and the radiator will not be hot.

At this time, it is necessary to adjust the water inlet valve of each radiator separately, close the valve of the first group of radiators into the house smaller, and open the radiator valve larger after that.

2) The user of the unit building, the upstairs and downstairs system is related, if there is a group of people who are not hot, you can go upstairs or downstairs to ask the neighbors, and if the corresponding radiator location is not hot, then you need to contact the property to overhaul the corresponding management.

2. The radiator is half hot and half is not hot.

This situation is also due to the residual air accumulated in the radiator or pipe, so the hot water circulation is not smooth, resulting in half hot and half not hot.

Two common reasons why a radiator system doesn't get hot!

Home heaters often have the problem that the existing radiators are hot, and some radiators are not hot, and the room temperature is not up to standard. And the radiators in the same parts of the upstairs and downstairs are not hot. This problem may be caused by several reasons, let's follow Brother Qi to find out.

First, the residents on the roof did not exhaust regularly, resulting in the same part of the upstairs and downstairs radiators not being hot. In this case, the first thing to do is to vent.

Second, if it is not hot after exhausting, then it is caused by the fact that the valve of the backwater pipe of the gutter downstairs is not opened, resulting in the inability of hot water to flow back; In this case, you have to find a heating station to open the return valve in the trench.

Third, if the backwater valve in the gutter is open, but the radiator is still not hot at home, then there is a problem with the heating pipe in at least one residential building, and this problem may occur in your own home, or it may occur in someone else's house upstairs and downstairs.

But in the third case, the problem is more complicated. At present, many residents like to modify and package their radiators without authorization, not only to move the original position of the radiators, but also to replace galvanized steel pipes with hot-melt aluminum-plastic pipes. As a result, in the process of retrofitting the heating, the heating pipes may be clogged or the hot water may not flow smoothly.

When the radiator is moved, an elbow is usually added to the pipe. As soon as the elbow increases, it will bring resistance to the normal flow of water. In this way, if A resists a little, B resists a little, C resists a little, and Ding resists a little more, it will cause the hot water to flow much slower than before the modification, which will cause the heating temperature to not go up.

When the pipeline is changed from steel pipe to aluminum-plastic pipe, some families or construction teams replace thick pipes with thin pipes in order to save costs. And the thin pipes definitely reduce the heat flow. In the hot melt pipe of aluminum-plastic pipe, due to the unprofessional and inaccurate technical mastery of many construction personnel, the hot melt temperature is either too high or too low.

When the temperature is too low, the docking will cause the pipeline to leak, and when the temperature is too high to dock the hot melt pipe, the problem of plastic silting and accumulation often occurs, which will block the pipe eye that is only one finger thick into an eye that is only one chopstick, resulting in a great reduction in the speed of hot water passing. This problem is not visible to the naked eye from the outside. The more such blockages, the slower the flow of hot water, and even the cooler it is, so that when the hot water flows down from the top floor, it passes through the middle of the house to dissipate heat, and then to the second and first floors, the hot water has already become cold water, and the heating can't heat up.

Therefore, in order to make the heating hot, it needs to be repaired.

However, during the repair process, some residents may refuse to cooperate with the repair because they do not agree to make a mess of the renovated home. Due to the long maintenance time, some residents refused to cooperate because there was no one at home. Therefore, residents should do a good job of communicating with their upstairs and downstairs neighbors.

1. Check whether the pipeline exhaust system is working normally. Especially for first-time or newly retrofitted users, the first thing to check is whether the exhaust valve installed at the high point of the pipe and the top of the radiator drains the air in the system.

2. Check whether the water inlet filter is unobstructed. The inlet pipe is hot, the return pipe is not very hot, the radiator is warm, and the exhaust valve is always released with warm water. At this time, the filter at the inlet valve should be checked to see if it is blocked, and if it is blocked, rinsing the filter with a brush and clean water can solve the problem.

3. Check whether the system pressure is large enough. If the temperature difference between the front and rear groups of the radiator is too large, it should be ruled out that it is not caused by gas accumulation and blockage, check whether the system pressure meets the requirements, and if the pressure does not meet the requirements, it is necessary to consider pressurization.

4. Check whether the hot water in the system is "approaching". For users with parallel branches of indoor radiators, if the existing branch radiators are hot and some branch radiators are not hot, most of them are caused by hot water "approaching the road". In this case, the inlet or return valve of the proximal radiator should be closed appropriately, so that more hot water can be supplied to the distal radiator.

Precautions for radiator installation:

1. When you plan to install the radiator, you need to plan where to install the radiator, which position has the best heating effect, which position has the best installation beauty, and which position has the best safety performance.

2. In the process of installing radiators, the most important thing is safety sealing. Special attention should be paid to the fact that there are no water leaks. From another point of view, that is, the difficulty of construction, do not change the position of the radiator at will without special circumstances, which will not only cause inconvenience to yourself, but also may cause inconvenience to others and neighbors.

3. After the radiator is installed, it is necessary to test and accept, like the usual production of this industry, after installation, it is indispensable for testing. Usually when replacing the construction, the workers will reserve the valve on the pipeline, and the stamping test should be carried out after installation.

Make sure that there is no leakage, dripping, bubbling water, and running water, and there is no problem with the installation of the radiator, and the test and acceptance of the radiator will be completed.

Recently, we have been receiving inquiries from users on a regular basis**. In such a situation, what should the user do can solve the problem in the shortest possible time. Today, I will give you a detailed answer.

Reasons why radiators are not hot

See if it's a problem with the boiler. In order to save fuel costs, some communities use inferior fuel for heating, resulting in substandard heating; It is also possible that the boiler water channel is seriously scaled, resulting in low boiler work efficiency.

Check to see if the circulating pump has a low pressure point. In order to save electricity, some heating management units will stop the circulating pump, resulting in the instability of the system and ultimately affecting the heating effect.

The make-up pump is low for the negative pressure point. If the radiator of a tall building is not hot, the user can check whether the make-up pump has a low pressure point, whether the make-up pump inverter is faulty, and the make-up tank is not timely, etc.

Whether the heat exchanger in the heat station is damaged. When the heat station carries out the secondary heat exchange, whether the heat exchange of the existing heat exchanger cannot meet the actual needs of the user due to the small selection of the heat exchanger, etc.

Supervision and management. Some heating operation units lack management mechanism, employees lack a sense of responsibility, and the outdoor temperature and weather continue to change during the heating period, but the heating management unit is not timely in regulation and control, resulting in heating errors.

The radiator does not heat the performance

The radiators of the whole complex are not hot enough.

None of the radiators in a user's home are hot.

Only a few of the radiators in a group provide good heating.

A set of radiators, not hot above, hot below.

The radiator is not hot solution

The radiators of the users in the community are not hot enough, and the general reason is that the heating temperature is not enough. If the radiators in the neighborhood are not hot, you can directly find a heating unit, and if the indoor temperature is not up to standard, the heating fee can be refunded.

If all the radiators in your home are not hot, then you need to check the reason, whether the home heater was hot last year, so as to determine whether there is a problem with the installed pipes, if it was hot last year, it is not hot this year, you can check whether the valve and temperature control valve of the radiator are open. If it still doesn't work, it should be that the radiator is blocked, and you can find a professional cleaning person to clean it.

If the radiator has several groups of hot and several groups are not hot, or check whether the radiator valve is open, this reason is generally that the radiator is collected in the gas, which is caused by the phenomenon of "gas blockage", and it is recommended to deflate the radiator.

The radiator is hot above, not hot below or not hot at the top, hot below, this should be a bad heating cycle, you can find a professional to test the water inlet pressure and return water pressure, to see if the pressure difference is too much, whether the heating in and out of the water pipe is reversed. If this is the case, the pipes need to be modified.

Through the above methods and summaries, it is found that the situation in your home is the third item in the solution to the radiator not hot.

The general reason why the radiator is not hot is that the radiator has gas accumulation, resulting in the phenomenon of "air blockage", after the occurrence of air blockage, it is difficult for hot water to circulate, resulting in the radiator not dissipating heat or dissipating heat slowly.

The correct way to deflate the radiator is not hot: the user gently loosens the manual air release valve by hand, and immediately stops twisting when he hears the exhaust sound, and if he sees a stable water flow out, he can gently tighten the air discharge valve. After a period of time, repeat the above actions, and complete the entire exhaust process after two or three reciprocating.

During the entire exhaust process, there is no need to release a large amount of hot water.

Generally, too many radiator groups in the home will cause the last few pieces to not be hot, and you have to find a master to solve this situation, such as thickening the pipe and adding a water tank; There is also a situation that the radiator is relatively small and not hot, which is the reason for "gas collection", at this time you have to find the exhaust valve to exhaust; If it is not the above situation, it is blocked by a foreign object, or it is broken.

There are many reasons why the radiator is not hot, firstly, a large amount of air enters the heating pipe during the water supply process and is not discharged in time; Secondly, the radiator of the radiator is seriously blocked;There are also radiators that are too old and the inner wall is scaled, resulting in poor water flowFinally, the water discharge valve and water circulation pump are installed artificially and privately.

1. Deflat.

2. Close the hot valve and only open the valve of the heating that is not hot. Heat, indicating that the heating is not blocked, the solution, the original hot heating valve is half open, the original is not hot wide open. Problem solving.

If it is not hot, it means that there is a problem with the installation of the radiator that is not hot (because some heaters have partitions inside, and they will not heat if they are installed incorrectly), or there is a problem with the pipeline. Your indoor tubing only.

The lower side of the new radiator is hot, the upper half is not hot, it is dry, there is no wind, there is no water.

Unscrew the vent if it is not hot to expel the air inside.

There can be many reasons why <> radiator is not hot, here are some common reasons and solutions:

1.Air inside the radiator: There may be air bubbles inside the radiator, which can cause poor water flow and affect the heating effect. The solution is to vent, which can release the air inside the radiator by opening the air release valve.

2.Radiator valve is not opened or blocked: If the radiator valve is flammed and not opened or blocked, the water flow cannot enter the radiator, causing the radiator to not be hot. The solution is to check if the valve is open, and if it is blocked, it can be cleaned with a fine needle.

3.Radiator pipe blockage: Radiator pipes may be blocked by dirt or substances, resulting in poor water flow and affecting the heating effect. The solution is to clean the pipes, which can be cleaned with a professional cleaner or by disassembling the pipes.

4.Radiator water pressure is too low: If the radiator water pressure is too low, the water flow will not be able to enter the radiator, resulting in the radiator not being hot. The solution is to adjust the water pressure, which can be solved by increasing the water pressure.

5.Radiator failure: If the above methods cannot solve the problem, it may be that the radiator itself is faulty and needs to be repaired or replaced.

In short, when the radiator is not hot, you need to check the cause of the problem first, and then take the corresponding solution. If you can't solve the problem, you can seek professional maintenance personnel to deal with it.

1.Reason:

1) Radiator exhaust port plugging: The radiator exhaust port may be blocked by dust, hair and other substances, resulting in the radiator can not be exhausted normally, which will affect the heat dissipation effect of the radiator and make the radiator not hot.

2) Radiator thermostat failure: Radiator thermostat malfunction, which will cause the radiator to fail to operate at the set temperature, so that the radiator is not hot.

3) Radiator power disconnection: The radiator power supply is disconnected, which will cause the radiator to not work properly, so that the radiator is not hot.

2.Workaround:

1) Clean the radiator exhaust port: Cleaning the radiator exhaust port can make the radiator exhaust normally, so as to restore the heat dissipation effect of the radiator and make the radiator heat up.

2) Replace the radiator thermostat: Replace the radiator with a radiator to make the radiator run according to the set temperature, so that the radiator can heat up.

3) Check the radiator power supply: Check the radiator power supply to make sure the radiator power supply is normal, so that the radiator can heat up.

The reason why the radiator is not hot may be disturbed, and the following are some common causes and corresponding solutions

1.Water pressure is too low: The radiator needs enough water pressure to function properly, and if the water pressure is too low, the radiator may not heat up. The solution is to check the water pressure in the heating system, and if the water pressure is too low, you can increase the water pressure by adding water.

2.Valve problems: There may be problems with valves on radiators, such as closing or clogging. Check that the valve is open and make sure it is working properly. If the valve is clogged, try cleaning or replacing the valve.

3.Valve problems: The air valves in the heating system may have air blockages, causing the radiators to heat up without their hands. Use appropriate tools, such as an air blemlower, to get the air out of the system to ensure a smooth flow of water to the radiator.

4.Pump failure: If the radiator doesn't heat up, it may be due to a malfunctioning pump. Check that the pump is working properly and repair or replace the pump if necessary.

5.Clogged water pipes: The water pipes of your heating system may be clogged with dirt or oxides, blocking the flow of water. This may require a professional cleaning service to clear the blockage.

6.Boiler problems: The radiator is not hot and may also be related to the boiler itself. Check the condition of the boiler to make sure it is functioning properly and providing enough hot water to heat the system.

If you are not sure how to solve the problem of the radiator not heating up, it is advisable to consult a professional heating system repairer or installer, who can conduct a more detailed inspection and diagnosis and provide an appropriate solution.
