In our time, the heating system is an integralpart of any industrial enterprise or apartment house. As a rule, if everything is properly installed, then such systems serve for a long time and reliably. However, if you want the batteries to last as long as possible, then flushing the heating systems is necessary. This procedure is necessary because after the heating season, a lot of scale and other dirt accumulate in the radiators, which travels along the pipes together with hot water and is deposited in various places. Preventive cleaning works will help the batteries last a full time. In addition to scaling the radiators, it also reduces the efficiency of the heating system itself. The presence of a scale layer even in 1 mm reduces the heat output by 15%. As a result, it takes more energy to increase the water temperature in the batteries, and the level of heat exchange decreases.
Intending to flush the heating system,To address to the expert on the given question. He will first diagnose the entire system and set the kind of scale that you need to get rid of. This is done in order to choose the right way to clean the radiator. Thus, washing of heating systems is divided into chemical, pneumohydropulse and hydrodynamic. Each of the methods has both positive and negative sides.
Chemical flushing
This is the most common way, becauseis very effective and does not take too much time. Such washing is carried out using alkalis, solvents and other chemical liquids. From here follows and a minus of such procedure - danger of work with materials. You need to do everything very carefully and know which solution to use. So, for example, you can not use alkalis and acid solutions if the radiator even partially consists of aluminum. Also it is forbidden to use "chemistry", if there is even the slightest danger of getting solutions into the sewage system - the evaporation of such substances can cause mass poisoning.
Hydrodynamic flushing of heating systems
From the name of this method it can be concluded thatThe impact force of the water produces descaling. The liquid stream is guided with special nozzles to the places of scale under very high pressure. At a cost, this procedure exceeds chemical cleaning, however, the quality will say for itself. When working with cast-iron batteries, hydrodynamic cleaning has proven itself well. With the help of "chemistry" they are quite difficult, and sometimes it was impossible to clean, and the owners even had to just change the batteries to new ones. However, this method turned out to achieve good results.
Special pneumatic pistol is the main toolsuch a method of cleaning. Very convenient and very effective method of washing batteries, the diameter of which is less than 150 mm. Such a gun can remove scale even from a distance of 50 m. It also surpasses "chemistry" in its efficiency and reliability.
