Cold radiators are a real torture for all living in an apartment. Low room temperature can lead to colds.
Therefore, you need to know the cause of the cold batteries in order to fix this problem as soon as possible.
The temperature of the radiators depends on the availabilityCoolant, which is most often water. If it is not available, the batteries will be cold, that is, they will stop heating the room, if the plumber will drain water from the heating system for any repairs.
Batteries can be cold due to airTraffic jams. Most often, residents of the upper floors of the house face this, since the air in the heating system seeks to go up. To get rid of air traffic jams it is possible with the help of the crane of the Mayevsky or the drain cock, which is on each battery.
During filling and starting of the heatingSystem plumber bypasses all the batteries in the house in order to check the temperature of their heating. During this process, called crimping the system, cranes are opened for the release of excess air. To do this, the cap is unscrewed in them, after which the valve opens, to which you need to press. But before that, do not forget to put a basin or a bucket under the tap. As a rule, not less than five liters of water is drained, after which the tap is carefully twisted.
The cause of cold radiators can beIncorrectly selected scheme for their connection. It is best to choose the diagonal method, rather than the side and bottom. If the coolant is supplied from the bottom, the top of the batteries often remains cold. To correct the situation, you can change the connection diagram itself or add a fluid flow extension.
Cold batteries in the apartment can becomeConsequence of poor circulation of water in them. Most often this is due to the formation of clogs and oskalin in the pipeline. All this prevents the flow of hot water. In this case it will be necessary to flush the pipes under pressure or replace them.
Sometimes cold batteries talk about wrongInstallation of radiators on the upper floors of the house. If people from above installed a modern battery equipped with a thermostat, but at the same time forgot about the device of the bypass pipe, then without the heat there will be a whole riser. You can correct the situation if you agree with the upper neighbors on the installation of this pipe.
