As you know, the efficiency of the heating system decreases even at the moment when it begins to be put into operation. According to statistics, during the first few months approximately 10% of the heating and working efficiency is lost.
Reasons for clogged heating system
In the process of circulation of the coolant through pipes, chemical processes occur. Sludge and corrosion of compounds lead to scale deposits over time. It settles on the internal surfaces of the system and reduces its performance. The massive scale layer insulates well and prevents heat transfer. Among other things, the scale layer leads to wear of the elements. In order to exclude an emergency, it is necessary to try to prevent it in time, because it is especially unpleasant in the winter season.
Signs of scale on the inner surface of the pipes
Before flushing the heating system in a private house, it is necessary to understand what signs indicate the appearance of scale. If the batteries are heated unevenly, and their lower part remains cold, then 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. The characteristic crackling that occurs when the boiler equipment is heated can also indicate scale. 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 is supplied to the pipe, then scum on the inner surfaces of the radiator may also indicate that the latter remains cold. Costs are increasing, which cannot suit the consumer. To date, the chemical and physical methods of cleaning the system are known . The physical should include hydropercussion and hydro-pulse washing, in which special equipment is involved - compressors. Chemical exposure involves the use of drugs with a biological or chemical component that can dissolve deposits of sludge and scale.
Cleaning with a pulsating water mixture
Before flushing the heating system in a private house with water, you should familiarize yourself with what a water-pulsating mixture is. 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, lift sand, salts, deposits, carbon deposits and corrosion. Subsequent air supply removes sludge from the system, preventing it from settling. It is possible to save energy resources due to pneumo-hydraulic pulse washing, while the service life of all systems is extended by 20 years or more.
The costs of cleaning in this way make up a maximum of 12% of the funds that would be spent on the work of replacing system components without changes and improvements. This method cleans the network without restrictions on the season, because there is no need to dismantle the batteries, as well as risers. As a result, heat transfer increases by a maximum of 95%. To flush the system in this way, it will not be necessary to rent special equipment.
The use of biological products
If you decide to flush the heating system in a private house, then you can use biological products. This technology is environmentally friendly and highly efficient. It is based on the use of microbiological drugs that are introduced into the system. They break down oily-mud, solid organic deposits, and the process itself does not involve disassembling or shutting down the system.
Another positive aspect of this technique is the safety of 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 100% clean up to the base in just a few days.
The use of air hammer
If you are thinking about how to flush the heating system in a private house with a closed circuit, then you can consider the method of pneumatic water hammer. It is applicable to older systems, and at times is the only sure way to reanimate heat. The method is based on the action of a hydraulic wave, which propagates at a speed of 1200 m per second. This force breaks through scale and plugs from the sludge, and the walls are not damaged. They are affected by a two percent force of the shock of the wave. While the remaining 98% affects deposits that are discharged through a flexible hose into the sewage system.
The use of this method allows to reduce the cost of building repairs. Operating costs are reduced, and there is no need to replace pipes and batteries. If you are thinking about how to 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 contamination of the pipeline, the diameter of which is only 4 inches. With a length of 60 m, the system can be cleaned in at least 5 minutes, and in a maximum of one hour, which is cheaper compared to major repairs.
Purification of the system with citric acid
Before flushing the heating system in a private house with citric acid, it is worth familiarizing yourself with this method. Some craftsmen argue that it is necessary to add a solution of washing powder and citric acid to the system. The resulting mixture is run for 24 hours, then drains, and the system is washed with clean water.
Next, water is added with the addition of “Kalgon” or another water softener for washing machines. As an alternative solution, a method is sometimes used that involves the purchase of a finished composition for flushing heating systems. This mixture is soluble in water and poured to the existing coolant. Rinsing is carried out according to the above technology, the mixture is then drained, and then the water that has passed the water treatment station is poured.
Flushing radiators
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 until the start of the heat supply system.
You should buy flush welded taps in the store, but the device that is assembled from a simple ball valve and a battery plug is considered the best. It is installed with running heating. It should be used to remove deposits of the type of sand from the batteries and their connections. Before flushing the heating system in a private house with your own hands, you must make sure that there is a hose with a fitting. However, it must be selected taking into account the diameter of the thread: it must correspond to this parameter on the flushing valve. A fitting is screwed into the washer valve, and the free end of the hose is diverted into the sewer hole. The flushing hose must be opened and wait 15 minutes.
Conclusion
If you have a question about how to flush the heating system in a private house, then you need to take care of the gas boiler, which is most often used for heating houses for one owner. Prior to this, it is recommended to resort to a mechanical or chemical method, but it is advisable to entrust prevention to specialists.
The boiler must be flushed separately from the system, therefore, during operation, it is disconnected and a temporary bypass is mounted. For annual maintenance, a rinsing method with ordinary water is recommended. In this case, deposits on the walls will remain small, and if you remove the circulation equipment and connect the supply and drain hose to the terminals, then most of the sewage will be removed. If you are thinking about how to flush the heating system in a private house, then the water should be supplied in the direction that is opposite to the flow of the coolant.
