Why hasn t the heating been hot this year, why x

Radiators have some hot and some are not hot, causes and solutions.

1. When encountering this problem, you should first find out which heating unit the building is heated by, and in principle, who supplies who is in charge, please find it to solve. If it belongs to central heating, it can be solved by contacting the heating unit responsible for the region. Sometimes the lack of heat in the building or indoors is due to construction and installation problems, which should be reported to the housing construction unit that built the building, and they are responsible for handling it.

If the pipeline in the community is in disrepair or out of balance, it should be repaired and adjusted by the property rights unit.

2. The air in the radiator is not released, blocking the flow of water, so that the radiator can not dissipate heat, which is also simple. It can be deflated by an exhaust valve (a small button-shaped valve at the top of the radiator) or by running the air.

3. It is the pipe of the radiator that goes in and out, and the radiator is only hot at the bottom, but not hot at the top. Caused by several possible causes:

It is the installation of the radiator that is down, that is, the radiator is installed on the top with a water retainer, and the bottom becomes straight, and the hot water is all gone away from below, because there is a water retainer on the top and the water flow cannot be exchanged, which causes the radiator to be not hot, and there are also half of the radiators that are not hot, half of them are hot. It is also caused by the water retaining sheet.

There is no water sheet, the water pressure is too large, the cold water and hot water barrier are washed out, and the cold water above cannot flow down. Such a situation is rare, as long as the water inlet valve is closed at a small point, there should be no problem without adding a water barrier below, but the heat dissipation is less than the original.

It's caused by too much air on it.

4. All the radiators in the house are hot in front and not hot in the back. This will happen if the pipe layout is a single pipe in series, as long as one set of radiators is turned off, the others are not hot. If the inlet water temperature is 75 degrees, after passing through the first group of outlets, it will become 65 degrees or 55 degrees and then enter the second group, and the second group of outlet water temperature will become between 55 degrees and 35 degrees, and in the end it will definitely become that the radiator is not hot.

The best way to solve this situation is to re-run the pipeline, and the second is to add a circulating pump. There's nothing else to do. Most of the irprofessional radiator sellers are responsible for this situation.

and some small companies with no HVAC qualifications.

5. The radiator goes up and down, it is definitely not hot, unless it is steam, and the pipe and the radiator standpipe are vertical, there may be hot spots, if it is not hot, the principle of not hot water is the effect of automatic convection of hot water and cold water, hot water will always rise by itself, and cold water will automatically sink, so the radiator is not hot. The solution is to change the pipeline to the opposite side of the upper and lower out, or the lower in and lower out with the stopper.

Dear, I'm glad to regret your problem The heating started to heat up and then didn't heat Answer: Dear, the heating started to heat up and then didn't heat up Reason: First, the poor quality of the radiator itself will also affect the heat dissipation effect, the inferior heating version is uneven, and the thermal conductivity is poor, easy to cause blockage, can not meet the requirements of the water circulation system.

In this case, the radiator with good thermal conductivity can only be replaced. 2. Hydraulic imbalance often occurs in a household-circulation system, which is prone to the situation that the radiator is hot in front and not hot in the back, which is caused by hydraulic imbalance in the heating circulation system. In this case, just close the heating valve first, then open the heating valve that is not hot separately, let it heat up first, and then turn on the hot heating after it rises.

3. Unreasonable gas accumulation, blockage or installation. If the exhaust is not carried out in advance at the beginning of heating, it will lead to large gas accumulation in the pipe hands and channels or gas accumulation at the end of the pipeline. Only open the exhaust valve on the side of the radiator to see, if it has not been solved, it is likely that the radiator is seriously blocked or installation problems, this kind of situation needs to be disassembled and inspected by professionals, and only after eliminating the blockage or installation problems can it be eliminated.

Fourth, the service life of the aging pipeline radiator of heating facilities is limited, if it is used for a long time and no maintenance work is done, it will lead to corrosion and scaling inside the pipeline, which will affect the poor heat dissipation effect of the gas sheet. In this case, try replacing the radiator again. Fifth, the installation of radiators without permission needs to be strictly implemented, some users change the radiators without permission, which is likely to cause heating blockage, increase water flow resistance, lead to some radiators are not hot, and even affect the heating effect of neighbors.

If this is the case, wait for the heating to end, and then my professional and technical personnel can carry out the transformation.

Hello, first of all, it may be that there is a large amount of air in the radiator pipe that is not discharged, which blocks the pipeline and causes the radiator to be partially not hot; Secondly, there may be a large number of impurities and dirt in the heating pipe, resulting in uneven heating of the radiator; Finally, it may be that the radiator is not hot due to improper installation or misconnection of pipes. Or the heating pressure itself is insufficient, there is water in the radiator itself, when the water is full, all the radiators will be under pressure, but the heating pressure is insufficient, and the cold water cannot be pushed out. It is recommended to find a professional for maintenance.

In the initial stage of heating, there is air in the pipe, which will cause the air plug to be blocked after water injection, especially the heating will not heat the top floor residents, and the user needs to open the exhaust valve on the heating package to exhaust the air. In general, the pipeline will get better after 2 to 3 days, if the cycle does not improve after 3 days, you need to notify the professional to open the roof exhaust valve to exhaust.

Reason 2: The filter is clogged.

The neighbors are warm, and the temperature of their own house is not good, mostly caused by the blockage of the filter and the poor flow of water, and it is generally good after cleaning the filter.

Reason 3: The valve is closed.

The valves installed by the user on the indoor heating pipe should be checked to see if they are all open.

Reason 4: Hydraulic imbalance.

If a building is hot and a building is not hot in the same community, the flow rate of the pipe network is generally unbalanced, and professionals can be asked to check the courtyard pipe network and adjust the valve to balance the water distribution.

Reason 5 for the heating is not hot: the user discharges water.

Individual users viciously discharge water, mopping the floor with water from the heating system, etc., resulting in the thermal imbalance of the heating system. The water of the heating system is equipped with chemical descaling agents, which are harmful to the human body and should not be used. Once the user is found to be maliciously releasing water, the heating center will dismantle the water discharge device and punish it.

Reason 6 for the heating is not hot: the pipes in the old community are aging.

The rot and leakage of the pipe network in the old residential area are frequent, the valve is rusted and cannot be opened, the inner wall of the heating package in the residential area is seriously scaled, and the water flow is not smooth, which directly affects the normal heating.

Reason 7: The heating system is changed by the user without authorization.

Privately add or move the heating package, and use radiators different from the original heating facilities, resulting in changes in water flow resistance and temperature differences. If the floor heating is modified without permission, if a circulating pump is installed, the heating temperature of the adjacent households will be low. Retrofitting households must change back to the original design and remove the circulating pump.

Reason 8: The design and construction are not standardized.

The heating transformation is completed by non-professionals, and the small pipe diameter, poor material selection of heating facilities, unreasonable pipeline direction, and non-standard installation will cause poor heating effect (such as: the pipe network is not the same height; The number of floor heating pipes installed is small, and the number of hanging radiators does not match the heating area; use of inferior color packets, etc.).

Reason 9: Poor house envelope.

Some old residential areas do not have external wall insulation, no corridor doors and windows, and the windows in the living room are single-layer glass, and the heat loss is great. It is recommended to implement external wall insulation transformation, install corridor doors and windows, and replace living room windows, and the room temperature can be increased by 2 3.

Reason 10: Decoration reason.

For the sake of aesthetics, some users will open up the balcony and living room, wrap the radiator, and install the wooden floor (the thermal conductivity of the wooden floor is worse than that of the floor tiles) during the decoration process, which will affect the temperature of the living room.

Reason 11: The occupancy rate of the new community is low.

The occupancy rate of new residential buildings is low, there are many households that do not need heat, and there are few households that use heat, and the temperature of their own homes will be lower than normal due to the heat consumption of vacant houses. In addition, if there is a large-scale power outage, water outage or extremely cold weather in the community, it will lead to unsatisfactory heating supply.

Because there is an air blockage in the pipeline, it needs to be deflated.

When the circulating pump is pressurized, the water in the pipe is pressurized by the circulating pump without air bubbles and then runs in circulation: if the circulating water is lost for some reason, there is a large amount of gas in the upper part of the pipe. Since air is less dense than water, the water at the high pressure end is blocked because it cannot hold down the air, so the water in this pipe cannot be circulated, and the heating is of course not hot.

First of all, talk about and is to check whether the valve is open to accompany the pat, Peiyu If there is no problem, release the air by opening the air valve, and it is generally OK, Rubens Heating hopes to help you.

Summary. Dear, the heating is not hot for reasons:

Dear, the heating is not hot for reasons:

1. Reasons for the heating system: the residents on the top floor close the door completely or partially, resulting in poor or interrupted circuits. Another factor is the blockage of the heating system, some heating systems that have been in operation for many years but have not received the necessary maintenance and maintenance, such as blockage, leakage and other phenomena affect the heating effect of the whole system.

2. The reason for the heating itself: most residents now use old-fashioned cast iron heating, and most of this heating is old. Therefore, if you want to heat up fundamentally, the best way is to use a cover-free one.

3. The heating has a water sound: it is mainly focused on the installation method of up and down out, because there is gas inside the radiator and cannot be discharged. The solution is to close the water supply valve of the radiator, open the discharge valve, discharge the gas inside the radiator, close the exhaust valve, and open the water supply valve.

4. Heating vibration: check whether the radiator pendant is loose, if the pendant is not loose, check whether there is a seismic source on the system that causes the radiator to resonate.

All need to be warm, and radiators can bring a comfortable experience. So what are the reasons why the radiator is not hot and what are the solutions? Let's follow the golden flagship flag brother to find out.

As far as a group of heaters is not hot, there are generally several reasons for this:

1) Accumulation of gas. If there is gas accumulation in the radiator or at the end of the pipeline, if there is gas accumulation in the radiator, the manual air running at the end of the radiator can be eliminated, and if there is gas accumulation at the end of the pipeline, the end pipeline release valve will also be released.

2) Hydraulic imbalance.

This situation mostly occurs in a one-cycle installation system in one household, and some radiators are not hot, and the hot ones are turned off and the non-hot ones can be heated up, which is called the hydraulic imbalance of the indoor circulation system. To deal with this situation, the room system can be adjusted to turn off the hot heater first, let the non-hot heater heat up, and then slowly turn on the hot heater. Note:

When turning on the hot heater, do not turn on all the hot heaters, and turn on them to a moderate degree, so that the original hot heater is also hot, and the heater that is not hot can also be warmed up.

3) Blockage or installation is unreasonable, unauthorized modification.

If the above methods cannot be solved, then the radiator or pipeline may be blocked or seriously installed unreasonably, and the unauthorized modifier will be given a warning and change back to its original installation form within a time limit. For the blockage or unreasonable installation, please ask professional maintenance personnel to disassemble and inspect to eliminate the blockage or reinstall the reasonably installed pipeline to eliminate it.

4) The system has a long service life.

The pipeline is seriously corroded, the pipe diameter becomes smaller, the original design does not match the current heating requirements, and it is easy to partially do not heat the situation, in this case, the pipeline can only be redesigned and installed.

How to deflate the heater:

1. When the upper and lower valves of the heating are all closed, you only need to gently loosen the gas release valve to hear the sound of gas discharge, and then immediately stop twisting the exhaust valve to let the gas drain by itself. Since the gas is piled up at the top of the radiator, it is easy to photograph the gas under the action of atmospheric pressure.

2. When the heater is deflated in the process, it is necessary to pay attention not to blindly deflat. This is because if you deflect the heating without judging the cause of the lack of heating, it will not only fail to solve the problem, but will also easily damage the heating hardware.

3. When opening the heating return valve, it should be noted that its amplitude should not be greater than the amplitude of the heating inlet valve, otherwise it is very easy to lose the water pressure in the radiator, which is not conducive to its exhaust.

4. The heating is good to choose the automatic exhaust valve, because the heating of the automatic exhaust valve itself has an intelligent design, which can not only automatically exhaust, but also cause water leakage, and can also be intelligently judged. This intelligent design also allows for tool-free installation and use, so the heating will not be inaccessible due to negligence or oblivion. If a steel radiator can be purchased, it can actually be fully maintained with water, so that the heating can avoid oxidation and corrosion, and have the effect of extending the life of the equipment.

Hello dear<>

The answer you are looking for: the heating is not hot because of the following reasons: it may be that there is still air in the pipe that is not discharged, causing air blockage and affecting water circulation; It could be that its valve is not fully opened; It may also be that the pipe has not been cleaned for a long time, and there are stains and blockages inside; It may also be that the radiators are connected in parallel, so it is easy to have the problem of not heating during use. The above is my reply to you, if you think my reply is good, please move your fingers to give me a five-element like<>
