How to rinse the heating system

Water used as a heat carrier in heating systems is constantly circulating through pipes. At the same time, such chemical processes occur as the formation of salts, corrosion of metal compounds. And the water itself may contain the smallest particles of the sludge, sand. All this sludge settles on the walls of heating batteries, forming a scale, deposit. The scale layer prevents high-quality heat exchange, unhindered water movement, leads to the wear of the elements of the heating system.

After installing the pipes of the heating system, flushing with cold water. Creating a strong pressure, start the water until it becomes clean at the output. Then, to remove rust, oily dirt, serves hot water. Further, the prevention is washed with pipes 1 time in 2-3 years.

On the cleaning of the heating system, it is worth thinking if you notice the following signs:

the upper and lower parts of the battery are heated unevenly;
pipes are heated longer than usual;
when water moves through pipes, cracking is heard strong;
cold radiator with hot riser.

For hydrodynamic washing, you will need:

rubber hose with a diameter of 25 mm;
compressor;
removal;
clamp;
drain tank;
ball valve.

Using a removal in the return to the heating system, we pump 4-6 atmospheres with the compressor. The increase in pressure will lead to chipping from the walls, scale, deposits. After 5-10 minutes, remove the removal, the compressor hose is removed, and we put the rubber hose in its place. The end clamp a clamp, we put in the bucket and discoverly. At the same time, the whole garbage comes out. We repeat the procedure several times. This method is particularly well helped to clean the cast iron batteries that are polluted most intensively. This washing option is safe, easy to use and cheap.

For chemical washing, solutions of organic, mineral acids, solvents, alkali are used. To carry out it should be prepared:

cleaning agent;
hoses;
pump;
capacity.

They are carried out in a similar way, but before starting work, the condition of pipes, equipment, their worn is determined so that the reagents do not damage the radiator. This method allows you to get rid of corrosion, scale, even in hard-to-reach places. When working, you need to use security tools. It is impossible to use for aluminum radiators, as the tightness of the compounds may be disturbed.

Washing pipes by biological preparations is effective, safe, does not require special equipment and disassembling the heating system. Microbiological preparations are served in the pipes, which, circulating through pipes, split organic, oily, solid deposits.

For highly contaminated, old heating systems are used pneumohydrogen. The shock wave created by the pneumopist is punched by screaming, sludge, not damaging the walls of the pipes. Deposits are derived through a flexible sleeve.

The disregard of the washing of the heating system does not lead to instant problems, but making it on time, you can avoid many troubles and extend the service life of the radiator.
