As you know, the efficiency of the heating system is reducedeven at the moment when it begins to be put into operation. According to statistics, during the first few months, approximately 10% of the efficiency of heating and operation is lost.
Causes of heating system clogging
In the process of circulation of the coolant through the pipeschemical processes occur. Sludge and corrosion of compounds over time lead to scale precipitation. It settles on the internal surfaces of the system and reduces its performance. A massive layer of scale is well heat-insulated and prevents heat transfer. Among other things, a layer of scale leads to wear elements. In order to eliminate an emergency situation, it is necessary to try to prevent it in time, because it is especially unpleasant in the winter season.
Signs of scale on the inside of the pipe
Перед тем, как промыть систему отопления в private house, you need to understand what signs indicate the occurrence of scale. If the batteries are heated unevenly, and their lower part remains cold, this is the first sign of the appearance of a thick layer of scale. You may also notice that it takes much longer to warm up the room than before. Scaling can also be indicated by the characteristic crackling that occurs when the boiler equipment is heated. This is due to explosions of water vapor when they penetrate the scale layer. In this case, the power of the device is reduced.
If hot water flows into the pipe, then scumon the internal surfaces of the radiator may also indicate that the latter remain cold. Increased costs, which can not satisfy the consumer. To date, known chemical and physical methods of cleaning the system. The physical should include hydraulic hammer and hydraulic pulse washing, which involves special equipment - compressors. Chemical exposure involves the use of drugs with a biological or chemical component that can dissolve sludge and scale deposits.
Pulsating mixture cleaning
Before flushing the heating system in a privatehouse water, you should take a closer look at what constitutes a water-pulsating mixture. This technology is based on the use of compressed air and water. Air is supplied to the heating system, the flows of which together with the liquid raise sand, salts, sediments, carbon deposits and corrosion. Subsequent air supply removes sludge from the system, preventing it from settling. Energy resources can be saved due to pneumatic-impulse flushing, and the life of all systems is extended by 20 years or more.
The cost of cleaning this way isa maximum of 12% of the funds that would have been spent on the work of replacing the system nodes with no changes and improvements. This method cleans the network without any restrictions on the time of year, because the batteries do not need to be dismantled, as are the risers. As a result, heat transfer increases by a maximum of 95%. To flush the system in this way, it will be necessary to rent special equipment.
The use of biologics
If you decide to flush the heating system ina private home, you can use biologics. This technology is environmentally friendly and highly efficient. It is based on the use of microbiological preparations that are introduced into the system. They break down oily-mud, solid organic sediments, and the process itself does not involve disassembling and shutting down the system.
As another positive point of thistechniques advocated safety cleaners for older systems. The drug is made on a water basis, and serves only to separate the dirt from the walls. The result is one hundred percent clean up to the bottom in just a few days.
Use of air hammer
If you pondered the question of howwash the heating system in a private house with a closed loop, you can consider the method of pneumatic shock. It is applicable to older systems, and sometimes it is the only sure way to reanimate heat. The method is based on the action of a hydraulic wave that propagates at a speed of 1200 m per second. This force punches scale and cork from sludge, and the walls are not damaged. They are affected by a two-percent force of the impact of a wave. While the remaining 98% affect sediments that are discharged through a flexible hose into the sewage system.
The use of this method allows to reducebuilding renovation costs. Operating costs are reduced, and the need to replace pipes and batteries is eliminated. If you are thinking about how you can flush the heating system of a private house, then you can consider this particular method, which for a limited time allows you to cope with the pollution of the pipeline, whose diameter is only 4 inches. With a length of 60 m, the system can be cleaned in at least 5 minutes, a maximum in an hour, which is cheaper compared to a major overhaul.
Citric Acid Cleansing System
Before flushing the heating system in a privatehome citric acid, is closer to get acquainted with this method. Some craftsmen claim that it is necessary to add a solution of washing powder and citric acid to the system. The resulting mixture is run during the day, then drained, and the system is washed with clean water.
Next, water is poured with the addition of "Calgon" oranother water softener for washing machines. As an alternative solution, a method is sometimes used that involves the purchase of a ready-made composition for flushing heating systems. This mixture is dissolved in water and poured to the existing coolant. Washing is performed according to the above described technology, the mixture is then drained, and then the water that has passed through the water treatment plant is poured.
Radiator flushing
If you are thinking about how to flush the heating system in a private house, then special attention should be paid to radiators. It is recommended to solve this problem before the start of the heating system.
In the store should buy flush weldcranes, but the best device is considered to be assembled from a simple ball valve and a battery plug. It is installed when running heating. It should be used to remove deposits of the type of sand from the batteries and connections to them. Before you rinse the heating system in a private house with your own hands, you need to make sure that there is a hose with a fitting. However, it is necessary to pick it up taking into account the diameter of the thread: it must correspond to this parameter on the flushing tap. A fitting is screwed into the washer valve, and the free end of the hose is retracted into the sewer hole. Flush hose must be opened and wait 15 minutes.
Conclusion
If you have a question about how to washheating system in a private house, you must also take care of the gas boiler, which is most often used to heat homes per owner. Prior to this, it is recommended to resort to a mechanical or chemical method, but it is desirable to entrust prevention to specialists.
Flush the boiler must be separate from the system,therefore, at the time of operation, it is disconnected and the temporary bypass is mounted. For annual maintenance, a method of washing with plain water is recommended. At the same time deposits on the walls will remain small, and if you remove the circulating equipment and connect the supply and drain hose to the terminals, then most of the sewage will be removed. If you have thought about the question of how to flush the heating system in a private house, then water should be fed in a direction that is opposite to the flow of the heat carrier.
