The first two pieces are hot, and the last one is not hot, and the reason why the bedroom is closed or turned down is hot: the situation caused by the presence of gas in the radiator pipes.

The solution is: if there is gas in the radiator pipeline, you need to contact professional maintenance personnel in time to clean and deflate the radiator pipeline, which can solve the situation that the radiator is not hot.

The filter screen on the > entrance pipe is a protective device to ensure that the indoor heating facilities will not be blocked. When the overall temperature of the indoor heating facility is obviously not hot, or the temperature of the heating facility is very different from that of the neighbor's heating facility on the same floor, it is likely that the filter is blocked. When a group of radiators in the room is not hot or half of it is not hot, it can be given priority to the pressure of air in the radiator.

First, the living room at home is equipped with two radiators, the first two are hot, the last one is not hot, and the main reason is that the bedroom is closed or smaller.

1. Gas accumulation. The indoor heating part is not hot because the radiator has gas in the area, which causes the phenomenon of "gas blockage", and it is recommended to vent the radiator.

2. Hydraulic imbalance. Some radiators are not hot, but the hot ones are turned off and the ones that are not hot can be heated up, a phenomenon called 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.

3. Blockage or unreasonable installation, unauthorized modification: If the above methods cannot be solved, then the radiator or pipeline may be blocked or seriously installed unreasonable.

Second, there are the following reasons why the heating is not hot:

1. The water supply and return pressure of the building is insufficient;

2. The amount of water supplied and the water temperature are insufficient;

3. The hydraulic imbalance of each branch pipe in the system;

4. Air blockage, cut off water flow;

5. The number of radiators is not enough or is not selected according to the actual water temperature;

6. The heat dissipation performance of the radiator is inaccurate;

7. Vertical imbalance of the system;

8. The pipeline is blocked or the valve cannot be opened;

9. The insulation condition of the enclosure structure is insufficient;

10. Insufficient heating time;

11. The new house or the neighborhood is not heated.
