As you know, the efficiency of the heating system decreases even at the moment when it is put into operation. According to statistics, approximately 10% of heating and operation efficiency is lost during the first few months.
Causes of blockage in the heating system
During the circulation of the coolant through the pipes, chemical processes occur. Sludge and corrosion of joints eventually lead to deposits in the form of scale. It settles on the internal surfaces of the system and reduces its performance. A massive layer of scale is well insulated and prevents heat transfer. Among other things, a layer of scale 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 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 heat up unevenly, and their lower part remains cold, then this is the first sign of a thick layer of scale. You may also notice that it takes much longer to warm up the room than before. Scale can also be indicated by the characteristic crackling that occurs when the boiler equipment is heated. This is due to explosions of water vapor as they penetrate the scale layer. This reduces the power of the device.
If hot water is supplied to the pipe, then scale on the internal surfaces of the radiator may also be indicated by the fact that the latter remain cold. Costs are increasing, which cannot suit the consumer. To date, chemical and physical methods of cleaning the system are known. The physical ones include hydropercussion and hydropulse flushing, in which special equipment is involved - compressors. Chemical exposure involves the use of preparations with a biological or chemical component that can dissolve sludge and scale deposits.
Cleaning with water pulsating mixture
Before you flush the heating system in a private house with water, you should become more familiar with what a water-pulsing 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, raise sand, s alts, deposits, soot andcorrosion. Subsequent air supply removes sludge from the system, preventing it from settling. It is possible to save energy resources thanks to pneumatic-hydropulse flushing, while extending the service life of all systems by 20 years or more.
The cost of cleaning in this way is a maximum of 12% of the funds that would be spent on work to replace system components without changes and improvements. This method cleans the networks without restrictions on the time of year, because the batteries do not need to be dismantled, as well as 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.
Use of biologics
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 preparations that are introduced into the system. They break down oily, muddy, hard organic deposits, and the process itself does not involve disassembling and shutting down the system.
Another positive aspect of this technique is the safety of purifiers for older systems. The drug is made on a water basis, and serves only to separate dirt from the walls. The result is a 100% clean down to the ground in just a few days.
Use of pneumatic-water hammer
If you are thinking about how to flush the heating system in a private house with a closed circuit, you can consider the method of pneumatic water hammer. It is applicable for old systems, and sometimes it is the only sure way to revive heat. The method is based on the action of a hydrowave, which propagates at a speed of 1200 m per second. This force breaks through scale and plugs from sludge, and the walls are not damaged. They are affected by a two percent force of the impact of the wave. While the remaining 98% affects the deposits, which are discharged through a flexible hose into the sewer system.
The application of this method allows you to reduce the cost of repairing the building. 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 pipeline contamination, the diameter of which is only 4 inches. With a length of 60 m, the system can be cleaned in a minimum of 5 minutes, a maximum of an hour, which is cheaper than a major overhaul.
Cleansing the system with citric acid
Before you flush the heating system in a private house with citric acid, you should become more familiar with this method. Some craftsmen claim that a solution of washing powder and citric acid must be added to the system. The resulting mixture is run for a day, thendrained and flushed with clean water.
Next, water is poured with the addition of Calgon or another 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 into the existing coolant. Rinsing is carried out according to the technology described above, 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 before the start of the heat supply system.
You should buy welded flushing taps in the store, but the best one is considered to be a fixture that is assembled from a simple ball valve and a battery plug. It is installed when the heating is running. It should be used to remove deposits like sand from batteries and piping to them. Before you flush 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 must be selected taking into account the diameter of the thread: it must correspond to this parameter on the flushing tap. A fitting is screwed into the flusher valve, and the free end of the hose is diverted into the sewer hole. The flush hose must be opened and wait 15 minutes.
Conclusion
If you stood before youthe question of how to flush the heating system in a private house, then you also need to take care of the gas boiler, which is most often used to heat houses for one owner. Prior to this, it is recommended to resort to a mechanical or chemical method, but it is advisable to entrust the prevention to specialists.
It is necessary to flush the boiler separately from the system, therefore, during operation, it is disconnected and a temporary bypass is mounted. For annual maintenance, the normal water flushing method is recommended. At the same time, there will be little deposits on the walls, and if the circulation equipment is removed and the supply and drain hoses are connected to the outlets, then most of the sewage will be removed. If you are thinking about the question of how to flush the heating system in a private house, then the water should be supplied in the opposite direction to the flow of the coolant.
