The pipes in the heating corridor are hot and the rooms are cold. What happened?

1. Check whether the return valve of the pipeline well is normal: turn off the water supply and drain the indoor water. If the water pressure decreases or there is no running water, it means that there is something wrong with the return valve and it needs to be replaced.

There is an air plug in the pipeline. Close the water supply valve and return valve, drain the water from the radiator in the bathroom (directly pull off the plug), and bring out the air in the pipeline through the water flow.

3. If some parts are not hot, you can turn down the valve of the hot radiator appropriately, and then open the valve of the hot radiator after circulating the pipes that are not hot to make them hot.

Extended data:

Heating standard:

The heating standard is about 18 degrees Celsius, and it is normal to increase or decrease it by two degrees. If the heating in public areas is not hot, you can consult the property management company first. If the property management company doesn't help you solve the problem, you can complain directly to the heating company, and there will usually be professional people coming to help you solve the problem.

Precautions:

1. Some users will open or close the heating valve of the radiator at will in order to adjust the indoor temperature when using the radiator. But this is not correct, because each valve on the radiator heating pipeline will affect its heating effect, and it is generally not allowed to open and close at will after adjustment.

2. The hot water generated by heating equipment cannot be used. Because the water in the radiator contains a lot of chemicals, if it is used for laundry, it will not only cost a lot, but also have a certain impact on its own health. At the same time, if the amount of water in the radiator is insufficient, it will affect the flow and pressure of the whole system and eventually lead to the temperature drop of the radiator.
