What are the reasons why Weifang is not hot in the early stage of heating?

Self-examination and exclusion method:

The usual practice is that "one's own house is not hot to look at the neighbor's house, the neighbor's house is not hot to look at the unit building, and the unit building is not hot to look at the community", which is the exclusion method from small to large.

If the neighbor's house is hot, it means that the problem is at home; The neighbor's house is not hot either. See if the whole unit building is not hot. If other unit buildings are hot, the unit building is not hot, and the problem lies in the heating circuit of your own unit building.

If the whole community is not hot, it depends on whether the community property company has posted an announcement, whether the heat exchange station or the secondary pipe network is faulty; We also need to see if there is any notice from our company and if there is any fault in the pipe network.

If there is a problem with the pipe network, the heating of the whole county may be affected; When the secondary pipe network fails, it will affect the community covered by the pipe network.

Check whether the valve is open:

Before heating enters the house, there is usually a valve control. If the heating is not hot, first check whether the valve is open. In many new residential areas, new residents and first-time heating users' homes, the valves related to heating pipelines may not be opened. Users should open the manual valve in advance before use. These manual valves include not only intelligent locking valves for domestic pipelines, but also sectional valves in residents' homes. For example, each heating pipe has a control valve. If the manual valve at home is not fully opened, the heating cycle will not be smooth, causing some heating pipes or radiators to be hot, while the parts without valves will not be hot.

Check whether the pipeline is blocked by sundries;

I believe many residents have encountered this situation. The radiator in the living room is very hot, but the radiator in the bedroom is very cold. This situation may be that the heating circuit in residents' homes is blocked.

At the beginning of each heating season, because the heating pipes are not used for a long time, some impurities may accumulate in them, and the water flow in the pipes is not smooth, resulting in the radiator not being hot. In addition, the long-term use of heating, heating pipes and valves aging may also affect circulation. Once the pipes are blocked or blocked, some rooms may be very hot and some rooms may not be too hot.

In this case, residents can try to exhaust first. If it can't be solved, please ask professionals to clear the pipes at home in time. The corners and ends of the heating circuit are easily blocked. It is best to dredge the pipeline after the end of the heating season and take countermeasures in advance, which will not affect the heating. It is best to dredge the pipes at home every two or three years.

See if "Qi" is blocked:

If the radiator in residents' homes feels half hot and half cold, it is necessary to consider whether it is "choking".

If it is judged that the exhaust valve screw has rusted to death, don't screw it rashly, so as to avoid the exhaust valve cracking and hot water heating. Ask a professional plumber to come to the house for repair. At the same time, residents living in high-rise buildings should regularly check the heating heat, and if the heat is uneven, exhaust it in time.

Nowadays, many residents will cover the radiator when decorating their houses for the sake of beauty. Because the radiator is sealed by the radiator cover, the air around the radiator cannot circulate, which affects the effect of indoor convection heat transfer. In addition, the radiator is sealed in the cover, leaving only a local area for radiation heat exchange to the air, reducing the heat dissipation area of the radiator, thus affecting the heating effect. According to the staff of the heating company, some users use long and large curtains in their homes to artificially separate the heating from the room, which will also affect the heating.

Not only that, when neighbors don't use heating or stop, it may not only cause poor circulation, but also lead to accelerated heat dissipation. In addition, whether a citizen's home is an energy-saving building has a great influence on the heating effect.

The heating suddenly stopped heating;

See if anyone is using the circulating pump. If the radiator at home is hot for a while and warm for a while, you can often hear the buzzing of the heating pipe, which may be that the neighbor is using the circulating pump.

Installing circulating pump without permission will not only affect the heating effect of adjacent users, but may even affect the hydraulic balance of the whole floor, making the whole building not hot.

Residents privately discharge water from heating pipes;

The heating system must have enough circulating water to maintain the normal operation of the heating system. If residents privately discharge the circulating water in the heating pipeline, it will easily lead to water shortage in the system, which will directly affect the indoor heating effect of residents, and in serious cases, it will lead to water stoppage and shutdown of the heat exchange station in the community.

Tips:

Heating needs a process. If the temperature rises too fast, the pipe network will not be able to bear it, which will easily bring more problems. In the first few days of heating, there will be a gradual warming process, as long as it is not particularly cold, it is normal. If the secondary pipe network or heat exchange station has just been repaired, the heating of the whole community will take eight or nine hours; If the household's heating facilities have just been repaired, it will take two or three hours to heat them.
