There are five groups of radiators in unified heating, and the last two groups have low temperature and just the right heat. Is the circulation bad?

Gently open the exhaust valve and it will soon become hot.

"The heating has started for a few days, and there are two groups of five groups of radiators in my house that have problems. By touching them, I found that the temperature on the side with water pipes was ok, and the farther away, the lower the temperature ... "Ms. Su, who lives in a neighborhood near Dongguan Street, told reporters that she consulted the residents upstairs and downstairs yesterday morning. The temperature of two groups of radiators in the same position is normal, and there is no uneven hot and cold phenomenon.

"What is the reason? Is there something blocked in the radiator? " Ms. Su said. Subsequently, under the guidance of the reporter, Ms. Su carefully opened the exhaust valve of the radiator. As the exhaust sound gradually weakened until it disappeared, she closed the valve, and another group of radiators with problems were also treated in the same way. After about 15 minutes, Ms. Su said that the radiator temperature was normal and the uneven hot and cold phenomenon disappeared.

It should be noted that if citizens find that some radiators in their homes are hot and some are not, it is likely that "air resistance" has occurred. They can carefully control the venting of the exhaust valve. It should be noted that all valves cannot be opened as long as the deflation sound is heard. Close the valve immediately after the deflation process is completed.

Privately modified equipment

Neighbors are normal, and their heat and cold are uneven.

"The neighbor's heating is hot, and the temperature of my radiator is relatively low, and several groups of radiators are uneven." Residents of a residential area in Hujiamiao reported that he opened the exhaust valve of the radiator, but the problem still exists.

In this regard, the reporter interviewed some heating enterprises and home heating equipment installers in our city, and learned that the reasons for the above situation may be that the heating facilities have been used for many years, the scaling on the inner wall of the pipeline affects the smooth flow of water, or the unauthorized modification of heating equipment leads to abnormal water circulation in the pipe network.

"This year, I asked someone to tear down the original radiator in the room and replace it with a new one. This is the first time that a new radiator has supplied water ... "When the reporter described the information interviewed, the above-mentioned residents admitted that they had not considered carefully when replacing the heating equipment, and said that they would contact the property management company and the unit that installed the heating equipment as soon as possible to solve the problem.

Scientific heating

Never change the equipment or install a "shield" without permission.

"Modifying the heating equipment at home privately will not only bring trouble to yourself, but also affect the normal heating of other households." The staff of a large heating enterprise in our city told the reporter that in the process of residential construction, there are strict standards for the selection and installation of related facilities, such as radiator specifications and room area matching. If it is modified privately, it may change the direction of the pipeline and affect the normal circulation of water.

"The location of the heating equipment is also very important. For example, many (radiators) are installed under the windows of the room to help the rising hot air stop and heat the cold air coming in from the windows. Changing the position will affect this effect. " The above-mentioned staff said that some residents installed a "protective cover" on the radiator during the renovation, which led to poor heating and cooling effects.
