The efficiency of the heating of a dwelling is largely determined by how well the seasonal work has been done in preparing its heating system for operation. That is why with the arrival of cold weather, the entire equipment entering the heating system is checked, and, if necessary, its repair is also performed. In this case, situations are possible when a battery that looks good with the beginning of the operational period heats up very little or does not heat at all.
This is most often explained by the fact that so-called “air plugs” are formed in the internal space of the batteries. To eliminate them, it is enough to blow the heating radiator, after which the indicated malfunction, as a rule, disappears.
Before blowing The radiators first of all should be worried about the tool used during the repair work. The following items should be included in the work package:
It is imperative to make sure that air plugs are the real cause of the detected malfunction.
If the batteries do not heat well
You can make sure of this in a distinctive and distinct manner. "gurgling" in the batteries, which are badly heated, despite the fact that hot water regularly enters the system. After finding out the reasons for the lack of normal heating of radiators, you can safely proceed to the removal of traffic jams.
Open the thermostat valve
General procedure for performing operations Their removal is as follows:
Experts recommend repeating this procedure several times, successively bleeding the air in portions. And only after it is completely removed from the system through the faucet of Mayevsky should water flow, which is collected in a previously prepared container. After the water pressure in the faucet stabilizes and the hiss in the batteries disappears completely, you can return the valve to its original position.
In the case when your radiators are not equipped with a special valve for air bleeding - we advise you to use another way to remove it. This method involves the use of a special fluid (kerosene or a mixture of WD-40), which are applied to the upper cap of the radiator in the area of the thread.
Then, with the aid of an adjustable wrench, the plug is carefully turned away until a characteristic hiss of air coming out of the battery appears and the water seeps into the container prepared in advance. After the hiss has stopped - return the plug to its previous position, first putting several threads of a special FUM sealing tape on the thread.
Deposits in the battery
A fairly common cause of poor heating the batteries in the apartment is settling on their walls of scale and foreign particles entering the heating system along with hot water.
Studies have shown that with a scale build-up of just 1 mm, the heat dissipation of the battery immediately decreases by 15%. That is why it is advisable to flush the heating system in accordance with the recommendations of specialists before the start of the operating season.
But first you will need to make sure that scale is the cause of the problems that have arisen, which is usually accompanied by the following characteristic manifestations:
Having finally made sure that limescale is present, you can proceed to the choice of the most suitable way of its removal in living conditions.In this case, you should know that the most effective, but at the same time the most expensive, is the method of hydraulic purging of the system, which is widely used along with other known methods of cleaning (such as chemical treatment, for example).
As already noted earlier, hydraulic purging of the heating system is the most effective method of cleaning the batteries from the accumulated scale on their walls.
Flushing of heating
When implementing this method, the working mixture under the high pressure is fed into the existing high-pressure riser from ordinary water and compressed air. To obtain it at home, you will need a compressor of the appropriate capacity, providing the required pressure in the purging channel and ensuring the removal of scale accumulated on the walls of the batteries.
Practice has shown that for modern apartments with cast-iron radiators, the method of hydraulic purging is the most suitable option for organizing work on their cleaning. In that case, if the implementation of this method in the home is impossible - you can remove the batteries and hand them over to a service center for cleaning, which has all the necessary equipment for this.
A specialist will talk in detail about carrying out hydraulic cleaning:
