What s the matter if the radiator isn t hot? How to solve it?

First check whether the main gate is open, whether the heating switch is on, whether the flow is increased, and then release the gas to see the effect, not to find the property master to repair.

Do you confirm that it's not hot all the time, or if it's not hot after it's hot?

Radiator FAQs.

1.Common faults: The heating is not hot as a whole. Exclusion method: Open the inlet and return valves.

2.Common faults: The heating is not hot (the valve is open). The heating is not hot at all. There is a sound of water in the heating. Exclusion method: There may be gas in the heater, and it needs to be deflated.

Method 1: Close the water inlet valve first. Open the running air bleed valve to exhaust, there is water overflowing, close the air release valve.

Method 2: Close the water inlet valve 3 4, and then close the return valve, open the valve to exhaust, and half-close the air release valve when there is water overflow. Reminder: After operation, when the fault still cannot be eliminated, notify the maintenance personnel.

3.Common faults: the temperature of the heating line is not enough, and the room temperature is too low. Exclusion method: low inlet water temperature, increase inlet water temperature. by the property inspection system.

4.Common faults: Water leaks from the inlet and return valves (near the heating direction). Exclusion method: Close the inlet and return valves. Notify the installation team for maintenance.

5.Common faults: Water leakage outside the inlet and return valves (near the main line). Exclusion method: notify the property of the semi-closed system valve; Notify the installation team to enter.

Reasons why the radiator is not hot: gas accumulation, hydraulic imbalance, air in the heating cavity, blockage of the pipeline, etc., solution: release hot water, adjust the circulation system, discharge excess gas, remove blockage, etc.

Reasons why radiators are not hot

1. Some household radiators are not hot because the radiators accumulate gas, resulting in the phenomenon of "gas blockage", after the occurrence of air blockage, it is difficult to circulate hot water, resulting in no heat dissipation or slow heat dissipation of the radiators.

2. Hydraulic imbalance, this situation mostly occurs in a household and a circulation installation system, if the hot radiator is turned off, the non-hot radiator can be heated up, this phenomenon is called the hydraulic imbalance of the indoor circulation system.

3. If some of the radiators are not hot, it is also possible that there is air in the heating chamber.

4. The radiator or pipeline may be blocked or seriously installed unreasonably.

Resolution

1. Gently loosen the manual air release valve by hand, stop twisting immediately when you hear the exhaust sound, and gently tighten the air discharge valve if you see a stable water flow out. 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.

2. It can be adjusted in the indoor system, turn off the hot radiator first, let the non-hot radiator heat up, and then slowly turn on the hot radiator so that all the radiators can operate normally.

3. Comprehensively inspect the heating system, open the radiator valve, and discharge the excess gas in the radiator cavity.

4. It is necessary to ask professional maintenance personnel to disassemble and inspect to eliminate blockages or reinstall the reasonably installed pipelines to eliminate them.

Radiators are not hot divided intoThe radiator is not heated as a whole; The heating is half hot, half not hot, and there is water inside the heating; In a house, some heating and heating is not hot, etcThese three situations are to be checked when they arise, and here's how to solve them.

1. The radiator is not heated as a whole

In the event of such a failure, the valve is usually closed before heating, and the ** valve and return valve can be opened.

2. The heating is semi-hot, half is not hot, and there is water inside the heating.

The reason for this failure is that the gas in the radiator is not being discharged and the air valve needs to be opened to release the air until the water flows out. You need to look at the air release valve, which is on the other side of the heating control valve, so you can use a screwdriver to adjust it. If you turn it counterclockwise, you can get the heating out.

It needs to be deflated several times, one or two is not enough to clean it up, and it will be deflated every other time. until exhausted. The bathroom's heated vent valve is located at the top of the heater. After operation, if the fault cannot be eliminated, please notify the maintenance personnel.

3. In a house, some heating and heating are not hot

In this case, the main flow of each heating is uneven, i.e., the resistance distribution is uneven, and the intake valve of each radiator needs to be adjusted. Once the debugging is complete, this issue can be resolved.

If the heating in the home is very hot, but the temperature in the room is very low, in this case, the selected radiators are too small and the number of radiators needs to be increased. Therefore, when buying a radiator, it is essential to actually measure it and calculate the size of the radiator based on factors such as orientation, surroundings, and pressure.

First of all, let's take a look at the phenomenon that the radiator will not be hot, if it is not hot, you can sit in the right seat.

Examples of phenomena:

1. The user radiators in the whole community are not hot enough;

2. All the radiators in the house are not hot; Some rooms at home have hot radiators, and some are not;

3. For a group of radiators, there are a few hot pieces and a few non-hot ones;

4. A set of radiators is hot at the top but not at the bottom;

5. A set of radiators is not hot on the top and hot on the bottom.

The radiator is not hot and there are probably only these phenomena, below, let's find out the reasons respectively, and then prescribe the right medicine.

Cause Analysis:

1. The radiators of users in the community are not hot enough, and the general reason is that the temperature of the heating is not enough. This requires neighbors to consult and communicate with each other, whether there is no hot phenomenon, to determine that it is not hot, just find the heating unit, and in 2011 has been stipulated that if the indoor temperature of the heating is not up to standard, you can apply for a refund of the heating fee.

2. If all the radiators in your own 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 opened. 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.

3. 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 inside, so it is recommended to release the radiator.

4. The radiator is hot above, not hot below or not hot above, 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.

Therefore, there are about three reasons why the above radiators are not hot: heat source problems, pipe installation problems (resulting in poor pressure circulation), and radiator problems (blockage, insufficient number of pieces, and unadjusted valves). Find the corresponding phenomenon, and then find the cause according to the phenomenon that the radiator is not hot, and finally find a countermeasure to solve it.

Whether the valve is open properly.

At the beginning of heating, the user should thoroughly inspect the entire radiator heating system. Make sure the valves of the radiators are all open properly. Generally speaking, radiator valves are adjusted before leaving the factory, basically only in two directions, when the handle is parallel to the pipe, it is open, and when it is rotated 90° vertically, it is closed.

If the valves are not fully opened, the heating effect of the radiator will be greatly affected.

Solution: You can screw the valve handle parallel to the branch pipe.

The radiator is blocked.

Some household radiators are not hot due to a large amount of air accumulation in the heating system, commonly known as "air blockage", after the air blockage, the hot water is difficult to circulate, resulting in the heat dissipation of the radiator is affected.

Solution: Drain the excess air from the radiator cavity. On the top and side of the radiator, there are air release valves, unscrew the valve counterclockwise, be careful not to let a large amount of water flow out of the cavity, you need to deflate a small amount of air many times until it is exhausted.

The radiator pipe temperature is low and the hydraulically is out of balance.

Water pressure imbalances often occur in single-cycle installation systems. If the radiator is turned off, the radiator that was not hot heats up, then it is caused by indoor hydraulic imbalance. In addition, in many central heating areas, there are many heating families, and if the terminal heating temperature is not increased at this time, no matter how good the radiator is, it will not heat up.

Solution: When the radiator is turned on, pay attention to turn on the radiator that is not hot first, and then turn on other radiators after the temperature of the radiator gradually rises to ensure normal operation. If it is a problem with the temperature of the pipes in the entire community, you need to contact the heating company to adjust the temperature.

The radiator magazine is clogged or modified and not hot.

The installation details of the radiator that have been privately modified cannot be ignored, and the non-compliant installation will affect the temperature of the radiator. There are also situations that may be caused by the pipeline being blocked by impurities, the system is blocked, and the heat dissipation is poor.

Solution: Ask professional HVAC maintenance personnel to come to inspect, clean the blocked part or redesign the installation.

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 the air, which can be used to vent the air inside the radiator by opening the air vent 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.

If your radiator burns for a long time, then it is still not hot, generally speaking, there are several situations, the first situation, that is, the installation is not suitable, sometimes we are installing air conditioning and heating next to the road, he is low lights in the distance has a height, so that his water or the temperature is high along the pipe, and then circulating, and when you come back, it is slightly lower, so that you can circulate, if it is not hot, one is that your heating equipment is not good, Another situation is very likely, your radiator installation does not meet the regulations, the other situation is wide, your radiator or pipe is blocked, the third case, it is likely that your pipe or radiator has gas in it, this is the reason for not heating the situation, the first can find a professional closed maintenance personnel to install for you, the second you can put the gas of the heating, the morning state will make your heating hotter, if the damage is really bad, you can add a circulating pump, This will heat up a little faster.
