Why is it necessary to flush the heating systems? Which method to choose?

Nowadays, the heating system is an integral part 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 along with the hot water travels through the pipes and is deposited in various places. Prophylactic cleaning works will help the batteries last a full period of 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.

Washing and repair of heating systems

Wishing to clean the heating system, you should contact a specialist in this matter. He will first conduct a diagnosis of the entire system and set the type of scale, from which 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 method, as it is very effective and does not take too much time. Such washing is carried out with the use of 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. It is also 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 massive poisoning.

Hydrodynamic flushing of heating systems

From the name of this method, it can be concluded that the impact force of water produces scaling. The liquid stream is directed 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.

Pneumohydroimpulsive flushing of heating systems

A special pneumatic gun is the main tool of this 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.
