What if the radiator is not hot?

First, what should I do if the radiator at home is not hot?

1. If the radiator and pipes are not hot, there are generally two reasons. It may be that the main valve of the corridor is not opened normally, so you need to contact the property or heating company for inspection. If they find it open, they should check the director of the corridor to see if the pipeline is blocked. If the supervisor blocks it, it needs to be repaired by a heating company or a property management professional to avoid causing greater losses.

2. If only the radiator is not hot. There are usually four reasons for this:

2. 1, the radiator valve is closed.

Judge whether the valve is closed. If the heating pipe touches the radiator and there is no temperature, the valve is not opened. Select and determine the type of valve. Under normal circumstances, the valve opens counterclockwise and closes clockwise. After opening, there will be the sound of water flow, and the radiator itself will have heat slowly.

2.2. A large amount of gas was stored in the radiator pipeline and was not discharged in time.

If you open the valve, you find that the radiator temperature is uneven or not very hot. Every year, heating will be tried in the early stage of heating, and it will not be too hot. If it is not hot after formal heating, it means that there is a lot of gas in the radiator after testing the water, which needs manual exhaust, and the exhaust can generally be solved by itself. First, close the inlet and outlet valves of unheated radiators, and prepare a screwdriver to facilitate water filling. The rag can prevent a large amount of water from gushing out and affect the beauty of the wall. Then, screw the exhaust valve counterclockwise with a screwdriver and listen carefully to the sound of exhaust. When there is no gas but water, tighten the exhaust valve clockwise, and then open the intake and exhaust valves, so that the radiator will start to heat up. If this happens again later, it needs to be repeated several times.

2.3. The radiator has been blocked for a long time.

Because the radiator has been used for a long time and has not been cleaned, sediment or other impurities will appear in the pipeline, which will lead to the blockage of the radiator, and the scale in hot water will continue to adhere to the radiator, resulting in a lot of impurities in the radiator. Stacking in one place for a long time will block up, leading to poor water circulation. If there is blockage, it needs to be removed and washed with high pressure water, and then installed. If it is still not hot after high-pressure flushing, it is necessary to check whether the pipeline is blocked. If the pipeline has no influence, a new radiator needs to be replaced.

2.4. Other users have increased the influence of circulating pump.

Because some users' radiators are not hot, users install circulating pumps on their own pipe network without authorization, which changes the local system circulation of the pipe network, causes the circulating water of their radiators to increase, and urges the surrounding users to have insufficient circulating water without being hot. The installation of circulating pump in one or more households in a building will lead to the disorder of pipeline circulation system in the whole building, the temperature drop, and even affect the heating effect of the whole community. If it is not hot, communicate with the heating company in time to solve it. Do not install illegally and cause overall damage.

If the above situation is ruled out, the problems such as the radiator not being hot can be fundamentally solved. If you have other problems, you need to find a professional to solve them. Don't blindly solve them, it will have serious consequences.

3. What if one or two sets of heating in the whole house are not hot?

Only some radiators are not hot. In this case, there is no need to be nervous. If a group of radiators are not hot, it may be because of uneven resistance of radiators, resulting in different water output. At this point, the water inlet valve of each radiator must be adjusted for treatment. Because of the radiator system, it may also be because of the problem of adjacent radiators between floors. 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 gas in the pipeline. As long as you follow the previous exhaust steps and put it a few times, you can resume heating.

Most radiator problems are here. If these inventory methods can't be repaired, you need to contact professional maintenance personnel for maintenance.
