There is a set of heaters after heating that is always not hot, what is the reason?

Although collective heating is in most northern areas.

The heating is uneven, a group of radiators is never hot. "I'm sure many people have encountered similar situations. What's going on? Bian Xiao will talk to you today.

If it doesn't heat up the first time you use it, it's likely to be caused by the heating system pipe connection. Usually, the hot water in the series heating system flows through the return water as the inlet water of the next group of heaters, and the cycle is reciprocated, so that the end group heater is not hot. Therefore, when designing and installing heating, it is best to use the form of parallel connection, and the heating is hotter.

If you find that there is a group of heaters that do not heat up after heating, it is most likely because of the following reasons!

One, the heating is not cleaned and partially blocked.

The heating in your home has been used for many years, so be careful! After years of use, the radiator will produce dirt. If not cleaned and dredged in time, the heat circulation of the heater will be unbalanced, resulting in uneven heating and one group of heaters not hot.

This is also the most common reason, so it is recommended that users clean the system in time and restore normal heating.

Second, there is too much gas in the heating to block.

If there is too much gas in the radiator, it will also clog the pipes, causing the radiator part to not be hot. At this time, it is necessary to open the air release valve set in the system to release the air, and be careful not to release water. The heater is not hot all the way, and there must be debris in it, so we first turn off the valve, remove the radiator of our group, and then check if there is anything blocked in it, and whether there is any running water, so we ask a professional teacher to clean it here during the cleaning process, so that our radiator can be cleaned with water and reinstalled, so that the radiator will be warm.

Third, district heating is insufficient.

The heating capacity of the community matches the configuration of the household heating to maximize the heating, but many households have more heating devices, but the heating capacity of the community is insufficient, so the heating is not as hot as other rooms. The most straightforward way is to turn off the heating when not in use.

It may be that the heating in your home is not turned on, or it may be that the heating is not cleaned up and it is blocked, or it may be because the district heating is insufficient, and the inlet and return water of the heating is reversed.

In this case, it is likely that the heating that is not hot is blocked, and the hot water cannot flow in, so it will not heat up.

This is because there is air in the radiator, so the hot water cannot be supplied, so it is naturally not hot.

This is because there is air in the radiator, so the hot water cannot be supplied, and it is not hot.

In this case, it is very common that the heating is not hot, and the hot water cannot be heated up without flowing in.

The last two groups of central heating home heating are not hot may be the main valve is closed, the hot water flow is unevenly distributed, the home pipeline problem, and the distance from the heating source is too far, which is described as follows:

1. Radiators at home.

And the pipes are not hot, this situation may be 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 to confirm that they are open.

2. 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.

3. It must be a problem with the plumbing in your own home. It's not a problem with central heating. Look for the exhaust vent on the radiator. If you don't have an exhaust outlet at home, go to the top floor of your building or where you have a valve in your building to vent the air.

4. The reason why the last two sets of radiators are too far away from the heating source, because the distance is too far away from the heating source to transmit the temperature, you can modify the radiators in your home and try to get as close to the heating source as possible.

Notes:

1. The surface of the radiator will inevitably have dirt in the air attached to the surface, wipe it with a clean rag, and rub it with a little soapy water when it is not good to wipe, and then wipe it with a clean water rag, which can not be cleaned with a strong corrosive solution, nor can it be scraped with sharp and sharp objects, so as not to damage the surface.

2. After the radiator stops running, it is necessary to clean the filter and filter screen in time, if it is found that there is too much sediment, it is best to flush the system pipeline to prevent the pipeline from being blocked due to the deposition of dirt and impurities during the stop operation, it is difficult to clean up after a long time, and it will be difficult to deal with the problems during the operation in the coming year.

It is because the hot water flow is insufficient, that is, the total water supply pressure is not enough, or the valve switch on the heating water pipeline is abnormal, etc.

It is recommended to look along the entire set of heating pipes to ensure that all valves that should be opened are opened to the maximum and that the bypass valves that should be closed have been closed. The valves on the main heating line have been opened to their maximum opening.

When necessary, the air should be discharged to the heating water pipeline again, and the impurities inside the pipeline should be cleaned.

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.

Central heating, some of the radiators at home are hot, some are not hot, first find the problem from the home heating pipe network.

1. Central heating is that each floor is equipped with a household valve well room, first from their own supply, return pipe valves and filters to check, check whether the water supply and return valves are fully opened, whether the filter screen is blocked, when cleaning the filter screen, use the return water to flush and exhaust the indoor pipes and radiators, and determine whether the indoor radiators and pipes are blocked by flushing and exhausting.

2. After excluding the water supply and return pipe network and filter of the household, enter the indoor to exhaust the radiators one by one, check whether the deflated air is blocked, and check the water supply and return valves of each group of radiators to see whether the water supply valve (or temperature control valve) return valve is flexible or blocked, and the ball valve or flow regulating valve for heating is affected by the water supply temperature and impurities in the pipeline for a long time, which will be blocked or malfunctioning (the valve stem rotates and the valve core does not move) will cause an open or semi-closed state, which needs to be eliminated one by one.

Collective heating, some radiators are hot, some are not hot, and the reasons why it is not hot:

1. The circulating flow of that group of radiators is small, and the reason for the small circulating flow is to see whether the pipeline valve is blocked and whether the hydraulic balance of the pipeline system;

2. It may be that there is air in the radiator, and the air occupies the heat dissipation space, and the air will be improved if it is discharged.

If it is a hot melt pipe, you can consider whether there is a problem with the hot melt, such as the hot melt plugging the inside of the pipe. If you change it yourself, get the master back, the heating characteristics are originally fast water circulation, water approach, your situation should be the closer to the main pipe into the house, the hotter, I am from the northeast, the general radiators are in series, and there are very few parallel connections, only geothermal heat is in parallel.

Then find a professional to see if there is a problem with the main pipe when the water enters or exits, such as the pressure is not high enough, or the valve is clogged.

The reason why the first three groups of radiators are hot and the last three groups are not hot is: the situation caused by the presence of gas in the radiator.

The solution is: if there is gas in the radiator, you need to seek help from professional heating maintenance personnel to remove the air in the radiator, which can solve the problem that the radiator is hot and not hot.

The radiators and tubes are not hot. When this happens, there are usually two reasons, either the heating valve is closed, or the pipe is clogged or ruptured. You can first go to the valve position to see if the valve is closed.

If you can't find the valve, you can ask the property staff to check it. If there is a blockage or rupture, it needs to be repaired by a professional immediately.

This is generally due to the presence of water in it.

At the location of the radiator steam outlet, there is a water drain valve, open this and drain the water inside, which can generally solve this problem.

The water pressure is not enough to circulate. There is air in the radiator at the back, open the last set of radiator vents and keep releasing water until hot water comes out.

It is caused by the fear of unclean air or uneven water diversion.

It is recommended to discharge air to the whole set of heating water pipelines first, discharge as much air as possible through the exhaust valve, properly adjust the manual valves in front of each radiator on the heating pipeline, change the heating water flow rate of each radiator, open the manual valve on the heating main road to the maximum opening, and close the bypass pipe valve.

If the heating condition does not improve, you should find a professional plumber to check and deal with it.

If the radiator is used for a long time, it will be clogged inside, resulting in hot in the front and cold in the back, if it is solved, the radiator can only be removed for cleaning, and the radiator can only be removed and cleaned up with baking soda and water, and then released after a few minutes, which can generally solve the problem.

At the beginning of heating, the pressure is small, you can put it empty, it is estimated that it can be better, and after a period of pressure, it will be fine.

My family just got it done. The first two groups are hot, and the back three groups are cool. Someone from the heating company said that the heating temperature control valve in my house is too narrow and silt sediment, and it must be completely removed to be unobstructed, and each group charges 150 yuan.

I asked the property plumber to clean the filter under the valve of the thermal inlet pipe in the hallway, and after 3 hours, the heating in the house was all normal. The people in the heating company are very bad, ask more so as not to be fooled.

Deflating may be a bad circulation.
