Causes and solutions of radiator not being hot

Is the floor heating at home hot? Every winter, the temperature in the house is 17- 18℃. I gave feedback to the property several times, repeatedly shirking and not giving a solution. I've never come to the door to find out the situation. Helpless, some heaters were installed this year. I hope it will be a warm winter this year.

What are the reasons and solutions for the radiator not being hot?

Many families use radiators to keep warm in winter, but it is not hot, which will affect the lives of their families. In fact, the radiator and the pipeline are not hot, only the radiator is not hot, only some radiators are not hot, and the pipeline is not connected properly.

Radiator is a kind of heating equipment which mainly focuses on heating. It is mainly used in the northern areas where winter is cold, and has the function of keeping warm. Cast iron radiators were mostly used in the past, but now more materials have been developed. In cold areas such as Northeast China, heating has replaced firewall and kang as new heating equipment for people. Many families use radiators to keep warm in winter, but it is not hot, which will affect the lives of their families. In fact, the radiator and the pipeline are not hot, only the radiator is not hot, only some radiators are not hot, and the pipeline is not connected properly.

The following are some specific reasons and corresponding solutions:

First, radiators and pipes are not hot. If this happens, there are generally two reasons, either the heating valve is closed or the pipeline is blocked or broken. First, you can go to the valve position to see if the valve is closed. If you can't find the valve, you can check it with the property manager. If it is blocked or damaged, it needs to be repaired by professionals immediately to prevent serious consequences.

Second, only the radiator is not hot. Generally, there are three reasons: first, the thermostat valve of the radiator is closed, second, the radiator is not exhausted in time, and third, there is a foreign body in 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 exhausted in time, it can be handled by itself. First, turn off the heating valve at home, prepare the basin for easy water connection, then screw on the bleeder valve and listen carefully for the sound of gas discharge. If there is, it will be awkward. After the gas is discharged, the water will slowly flow out to see if the water flow is stable. If it is stable, you can close the bleeder valve and observe whether the radiator becomes hot. If not, repeat the above steps, and the heater will slowly heat up. This is a common fault phenomenon, so don't panic.

If the above two situations are ruled out, it should be that there is a foreign body in the radiator that causes the blockage. You must find a professional to dredge it, and don't blindly handle it yourself, which will cause serious consequences.

Third, only some radiators do not give off heat. There is no need to be nervous in this case. If a group of radiators are not hot, it may be because the heating resistance is uneven, which makes the water flow large and small. At this point, it is necessary to adjust the water inlet valve of each radiator. Because of the heating system, it may also be because of the radiator problem of the neighbors upstairs and downstairs. You can consult them. If everyone has the same problem, you can find a professional to carry out unified maintenance.

In another case, it is half hot and half not hot. The reason for this imagination is that there is a lot of excess air in the radiator or pipeline. Just follow the previous exhaust steps and put it a few times to restore heating.

Fourthly, the problem of pipeline access.

This is also a problem that new users may encounter. The possibility of this problem is slim. In fact, it is the wrong connection of the outlet pipe of the heater, which leads to poor thermal circulation and the heater is half hot and half cold. After eliminating the above common situations, find a professional radiator installer to solve them. This requires more attention to the use time. In addition to external cleaning every day, users can also carry out internal cleaning after several years of use to remove pipeline dirt.

Five, the pipeline unobstructed

After the radiator is installed, it is usually used in the heating season, and little attention is paid to it at other times. However, after long-term use, it is inevitable that some sediments will be produced, causing pipeline blockage. Because the radiator is not hot, users can handle it according to the actual use of the radiator. If the problem is too big for users to handle, they should contact the heating installation company in time for handling.

If these troubleshooting methods can't be repaired, you need to contact professional maintenance personnel for maintenance. When installing the radiator, the owner must choose a professional and formal company, pay attention to its daily correct use, and insist on doing the corresponding cleaning and maintenance work. Only in this way can the performance of the radiator system meet everyone's daily needs and effectively extend the life of the radiator system.

What is the reason why the radiator is not hot?

Causes of radiator blocking: Some household radiators are not hot. The general reason is that the radiator has gas accumulation, resulting in "gas blockage" phenomenon. After the air jam occurs, the hot water is difficult to circulate, resulting in the radiator not radiating or radiating slowly. Solution: The correct way for the radiator to deflate without heating is that the user gently twists the manual deflation valve with his hand and stops twisting immediately when he hears the exhaust sound. If there is a steady flow of water, he can gently tighten the bleeder valve. Repeat the above actions after a period of time, reciprocating for two or three times to complete the whole exhaust process. There is no need to release a lot of hot water during the whole exhaust process.

Causes of hydraulic imbalance of radiator: hydraulic imbalance often occurs in one household and one cycle installation system. If the thermal radiator is turned off, the non-thermal radiator can be heated. This phenomenon is called hydraulic imbalance of indoor circulation system.

Solution: Adjust the indoor system, turn off the hot radiator first, let the non-hot radiator heat up, and then turn on the hot radiator slowly, so that all radiators can work normally.

Check whether the radiator valve is open. Reason: When a radiator is not hot, users should check the heating system comprehensively. First, check whether the radiator valve is open. Radiator valves are generally ball valves, which have been adjusted before delivery. Generally there are only two directions. The handle opens when moving along the pipeline and closes when rotating 90 degrees. If some radiators are not hot, there may be air in the heating cavity. Solution: Exhaust the excess gas in the radiator cavity and block it, or install it unreasonably, or modify it privately. Cause: radiator or pipe may be blocked or seriously installed unreasonably.

Solution: It is necessary to ask professional maintenance personnel to carry out disassembly inspection, eliminate blockage or reinstall the pipeline reasonably.

There is something wrong with the parallel heating system. Many household heating systems adopt parallel connection, and the ratio of single radiator without heating for users of parallel connection system is higher than that for other users. In this case, parallel users must first do two things: the import and export of each radiator should meet the standards; Check that there is no excess gas in all radiators. Then users should patiently adjust the water consumption of each group to reach a relatively balanced flow level. Finally, reopen all radiators for inspection.

What is the reason why the radiator is not hot? What is the solution?

In the cold winter, heating is our indispensable heating system. Users often encounter the problem that the heating is not hot when using it, which makes people very headache. So what if the heating is not hot? What is the reason why the heating is not hot? Cause of heating system Check whether the heating system is blocked. You can touch the pipe connecting the heating first. If the pipe is not hot, the heating system may be blocked. The blockage may be due to the fact that the heating pipeline has not been maintained for many years, and a large amount of scale and sediment accumulation lead to scaling on the inner wall, increased thermal resistance and poor water flow; The central heating area may be caused by closing the valve of the main pipeline by mistake. There is an air plug in the heating pipe. Check whether the system flow is too low or whether the air content of circulating water in the system is too large. Touching the heater by hand is cold, which may be caused by the failure of the drain valve of the heater, which leads to the accumulation of a large amount of air in the heater and makes the heater not hot; There is water in the heater, or there may be gas in the radiator that can't be discharged. Man-made reasons Man-made reasons lead to the heating is not hot, such as users' disorderly deflation, water release, unauthorized heating, failure to pay heating fees, etc. This may affect the heating in your home. The heating effect of the heater is related to many factors such as the product itself, after-sales service, user's usual usage habits and so on. Part of the reason why the radiator is not hot is that there is an air plug inside the radiator. How to deflate the radiator and solve the problem of not being hot? In fact, it only takes five steps, and we can easily deflate the radiator and make it hot in winter! During the whole operation of the radiator system, gas will be continuously generated inside the pipeline, which will be stored at the highest point of the system. When these gases accumulate to a certain extent, there will be "gas blockage" phenomenon, which will hinder the flow of water in the system pipeline, and the heat conduction radiator will not be hot or heat unevenly. Therefore, the bleeder valve is an indispensable part of radiator heating system. The bleeder valve, also called the exhaust valve, is generally installed at the highest point of the system to let off gas and make the heating system circulate smoothly. There are also many kinds of radiator relief valves: safety valves, globe valves, check valves, gate valves and butterfly valves. In the radiator deflation step, the user should first check whether the pipeline water inlet valve is in the open state; Close all indoor valves; When the upper and lower valves are closed, the user gently unscrews the air valve, and immediately stops unscrewing the air valve after hearing the sound of exhaust, so that the gas can be discharged by itself. Because the gas in the radiator accumulates at the top of the radiator, it is easily released under the action of atmospheric pressure; Gently loosen the water inlet valve until a steady flow of water flows out, and then close the exhaust valve. This step must be patient, just unscrew it a little and hear the sound of water, otherwise the gas will not be easily discharged; Repeat the fourth step for many times until all the gas is exhausted. Some users have a lot of gas in the radiator system pipeline, which needs repeated exhaust to ensure the stability of heating. There are many reasons why the radiator is not hot, and the air blockage of the radiator is the most common one. If the radiator does not heat up after the user deflates, it is recommended to contact Comfort 100 and other professional institutions for on-site inspection and maintenance.

What is the reason why the radiator is not hot?

The best answer+answer 2+ adaptation 2 life-home decoration radiator is not hot? The solution in the radiator is not hot. There are many reasons why the radiator is not hot, including many internal and external causes. The radiator is not hot because of water supply and circulation factors, both because of low constant pressure point and water supply pump failure. But many people don't know how to deal with such a problem, so the following small series will teach you the solution that the radiator is not hot! First, introduce the reasons why the radiator is not hot: water supply factor: 1, low constant pressure point: low constant pressure point of water supply pump, and the high-rise building in the system is not hot.

2. Supply pump failure: There is a problem with the supply pump, and there is no spare pump, so the system is seriously short of water. 3. Inverter failure: the inverter of the water replenishing pump failed, and the water replenishing was not timely.

4. Water shortage of expansion tank: Due to water supply signal failure and other reasons, the expansion tank is short of water.

5. Small make-up water tank: the system is seriously short of water, and the volume of make-up water tank can't meet the need of water replenishment.

6. Water cut-off: It was caused by accident, and it may happen in other water-deficient cities, so it is impossible to replenish water. The heating is not hot due to circulation factors: 1, and the circulating pump is faulty: there is a problem with the circulating pump, and there is no spare pump, so the system does not circulate.

2. Intermittent circulation: In order to save electricity, some heating management units often stop the pump, and the system working conditions are unstable.

3. The flow rate of the circulating pump is small, which leads to a large area of no heat for users. 4. Low head of circulating pump: resulting in end users not being hot.
