The heating has already started, and the heating at home is not hot. How to solve it?

In the first few days of central heating, the easy problem is that the heating is not hot. In the same community, some homes are more than 20 degrees, and some are as cold as an igloo. So, what is the reason why the heating is not hot? What shall we do? Today, Golden Flagship Flag Goth will send you a solution that is not hot, hoping to help you get through the cold winter smoothly ~ Let's take a look with Golden Flagship Flag Brother.

Radiator is half hot and half not hot, radiator has water noise, or radiator temperature is not as high as others' home.

Causes and solutions: In the process of pipeline heating, the hot water in the pipe network will produce a large amount of gas, which is easy to cause gas blockage in the pipeline, thus affecting the normal circulation of hot water and causing one or several groups of radiators in residents' homes not to be hot, which is a common phenomenon that will appear in the early stage of heating every year. It is necessary to open the exhaust valve until the water flows out. Deflation method: the radiator is on the upper side, the toilet heating is on the top, and there is a deflation valve, which can be adjusted with a screwdriver. Turn counterclockwise to release the air in the heating, so that the heating becomes hot, and it needs to be deflated several times according to the situation until it is exhausted. Note: Do not screw large bolts under the heater near the ground.

The radiator at home is not hot, and the pipes are a little warm.

Reason and solution: This situation may be to prevent the radiator from rusting. Before the end of heating last year, the group valve of each radiator was closed, which can prevent air from entering the radiator and make the radiator rust and rot. At this time, it is necessary to open the sub-valves of each group of heaters.

The living room is hot, but the bedroom is not. Let's see if the heating, water supply and return valves in the bedroom are open.

The valve is not open, which is also one of the reasons why the heating is not hot at the beginning of heating.

"Many users have installed valves on the upper and lower pipes of heating when decorating. After the start of the heating season, if the valve is not opened in time, the temperature will be low or uneven. " Yonggui Li told a reporter an example: In the seventh district of Dongfeng New Village, some residents reported that the heating in their home was cold, but they wanted to drain water but found that there was no water in the heating. The heating maintenance personnel came to the door to check and found that although the water supply pipe valve of the top floor bedroom heating was opened, the backwater valve was closed, resulting in that the heating water did not circulate to the downstairs residents at all.

"I forgot to switch because I didn't know how to switch the valve. This is not a case. There are too many such things in the early stage of heating. " Yonggui Li said that many valves are installed by young people, and houses are for parents. After the heating started, many old people didn't know how to turn it on and off, which led to the low temperature of their own homes and downstairs residents.

The radiator and pipes at home are not hot.

Cause and solution: This may be because the main heating valve is closed, which is generally in the manhole of the unit staircase. We just need to check the supply valve and the return valve to make sure they are open.

All the heating in the house is close to the heat of the entrance door, and the farther away from the entrance door, the lower the temperature.

Cause and solution: turn off a group of heaters, and all heaters are not hot. This situation is caused by the series connection of radiator groups. For example, the water temperature in the pipeline entering the house is 65 degrees, and it becomes 55 degrees after passing through the first set of heaters. After entering the second group, the temperature may drop to 45 degrees, and then the temperature will be lower, and the radiator will definitely not be hot. In this case, you should contact professional maintenance personnel as soon as possible.

The radiator in the neighborhood is hot, but the radiator in the whole house is not hot.

The reason and solution of not being hot: It may be that the flow rate of the valve at home is too small. When heating a home, there is usually a valve to control it. If the radiator is not hot, it is likely that the valve is too small. At this time, just unscrew the valve to increase the water flow, and the radiator will become hot after a while.

The radiator part is not hot, or only the main pipe below is hot.

Causes and solutions of no heating: wrong installation method of radiator. If the radiator with four ports (also called "upper inlet and lower outlet") is installed as "lower inlet and lower outlet", water will flow directly from the lower main pipe, only the lower main pipe is hot, and the upper radiator is not hot; the radiator installed as "upper inlet and lower outlet" is installed as "upper inlet and lower outlet", and some radiators are not hot, and so on. Solution: Find the HVAC company that installed the radiator to reinstall or replace the radiator.

The radiator is quite hot and the room temperature is low.

Causes and solutions: After the heating starts, some households may have hot heating in their homes, but the temperature at home is not high. There are many reasons for this. If the house insulation effect is not good, the window leaks air, etc. The temperature will definitely not come up. In addition, if the radiator is decorated, it will also affect heat dissipation. Living on both sides, the top floor or the bottom floor of a building is also easily affected by the circulation of heating equipment. If there are few residents in the whole building and the residents are scattered, it will also lead to increased heat dissipation. In residential buildings with household heating, if neighbors stop heating, the heat transfer between households will inevitably have a certain impact on household heating.
