There is heating protection in northern China every winter. However, the heating time is not uniform and fixed, but each province and city will decide whether to start heating according to the weather conditions. So, what is the national heating time in 2019? When will your city heat up in 2019? Let's refer to the start and end schedule of heating in 2019.
National heating time in 2019: what month to what month? Starting and ending schedule of heating in 2019
2019 heating
The national heating time generally starts in November and ends in March of the next year. Some cold areas will be in October, and the colder areas will be in September.
2019-2020 heating time in Harbin, Heilongjiang: it is expected to officially heat on October 20, 2019
2019-2020 heating time in Changchun, Jilin: it is expected that the formal heating will end on October 20, 2019 and April 6, 2020.
2019-2020 heating time in Shenyang, Liaoning: November 1.
2019-2020 heating time in Beijing: November 15, 2019 - March 15, 2020 (legal heating time)
2019-2020 heating time in Tianjin: expected November 15, 2019

The above dates are for reference only. The annual heating time will be implemented in various regions according to the weather conditions.
Why is the heating not hot?
Heating
1. Heating vibration
Check whether the radiator pendant is loose. If the pendant is not loose, check whether there is a source on the part that causes the radiator resonance.
2. The main part of the heating is not hot
It mainly focuses on the device mode of bottom in and bottom out, because there is gas outside the radiator that cannot be discharged.
The treatment method is to open the exhaust valve to exhaust the external gas of the radiator. Or check whether the pressure difference of parts is too small or the flow is too low.
3. Heating itself
At present, most of the residents still use the old cast iron heating. Most of this kind of heating is old and needs to be dressed up by the heating cover. The decoration effect is improved and the quality of life is reduced. It is' beautiful and frozen '. Some residents simply open the heating cover in winter. However, the heat dissipation effect is greatly reduced. In order to heat up basically, the method is to use the new type of heating without cover.
4. The heating is not hot as a whole
Check whether the upper and lower position of the guide valve is reversed when checking the radiator device; Check whether the flow valve is not opened when checking the radiator device. Whether there is a problem with the part.
5. Causes of heating parts
The residents on the top floor completely or partially closed the intercept door to form a poor circuit or infill. Another factor is that the heating is blocked piecemeal. Some heating parts that have operated for many years but have not lost the necessary maintenance and maintenance show blocking, leakage and other phenomena, which affect the heating effect of the whole part. In addition, the heating capacity and heating area of the original design of the community do not match, forming a 'small horse pulling a cart', and the above problems should be handled by the property management department.
6. The heating has the sound of water
The main reason is that there is gas outside the radiator that cannot be discharged.
The treatment method is to close the water supply valve of the radiator, open the exhaust valve, exhaust the external gas of the radiator, close the exhaust valve, and open the water supply valve. If it cannot be cleaned, check whether the flow of parts is too low or the air content of circulating water of parts is too large.
