Water heating is not always quiet heating system. Sometimes you can hear strange noises coming from the pipes. Some of them are harmless and can be ignored, while others serve as a signal that there are serious problems. Try to understand why water noise in the heating pipes, and what can be done.
What kinds of noise may produce pipes
About sounds emanating from the elements of heating systems, is legendary. Under certain circumstances, the house is not only noisy heating pipes, but also other lines. In this case, the volume range for all sanitation systems is approximately the same. The most "musical" are metal tubes, but the plastic can "please" unusual melodies. water heating system can emit a variety of sounds:
- murmur;
- gurgling;
- rattling;
- knock;
- crack;
- clicks;
- hum;
- whistling;
- howl.
Specific sounds signal the presence of faults in the heating system, so you need to quickly identify and eliminate the source of the noise, as its systematic impact on the human leads to disorders of the nervous system, interferes with sleep and reduces performance.
Why noisy heating water pipes
Noise in the heating pipes cause the following reasons:
- air plugs;
- high velocity coolant flow due to incorrectly chosen diameter pipe or pipe inner lumen decrease due to overgrowth of its walls;
- coolant leak at the emergency site or through poorly sealed valves;
- exfoliated scale on pipe walls or debris caught in a loop during installation;
- faulty or improperly installed valves;
- excess power or pump installation with impairment;
- Wear adjustment valves or thermostatic heads;
- Cavitation - the formation of vapor bubbles in the coolant in the area of sharp increase in the diameter pipe (low-pressure region emergence), followed by the collapse of that Deplete equipment;
- violation mounting technology (use of polypropylene pipe diameter smaller than the calculatedNo observance of the minimum distance between parallel portions of the metal pipe during installation, the installation of the filter or valve not indicated in the flow direction therein, etc.).
Important! Central heating is always turned noisy. When filling the system audible murmur coolant heating circuit is accompanied by clicks, and exits from the air - whistle. Maintenance of heating equipment before start-up can also be performed using impact. Such noises are usually disappear when the system will come into operation, and are not a cause for concern.
If there were other sounds in the middle of the heating season or disappeared after the launch, it is a signal the presence of faults, with the problem should be sought not only or at the neighbors through the riser, but also in the thermal point of elevator or node - the source of the trouble may be far beyond the housing, as the sound waves propagate well through the pipes.
Methods for neutralizing the noise
The noise source often to Communications obschedomovyh locations. coolant pressure at the input of a heating unit is the highest, so the slightest fault in it can then express themselves in the form of strange sounds on the whole staircase. In a private home it is the noisiest place, the combustion or Thermo-generated, where the boiler is located, and the whole system of its binding.
On a note: Particularly sensitive to changes in pressure and bimetallic aluminum radiators. Thin metal passes through any self oscillation, as a mouthpiece. In these heating devices slightest technological noise gets amplified sound.
If the problem was a fault in the collective ownership of the equipment, then it should not be self-eliminating. Worn components can literally fall apart at the slightest attempt to untwist them, and all the blame will be placed on those who illegally interfered in the work "perfectly tuned" system. It is better to submit a complaint to the authorized service center and wait patiently for their representative to repair faulty units.
If it was possible to diagnose problems within their own or a neighbor's property, you should as soon as possible to do their liquidation. In this case, any delay is fraught with aggravation of the situation and the increasing complexity of repairs.
How to get rid of noise in the heating system
Each fault in the heating system only creates the characteristic noise for her appearance, which prompt the diagnosis. The list of measures depends on what sounds to emit heating pipes.
Buzz, whine
The loudest and most obnoxious noise appearance. Pipes can zagudet unexpectedly and give rise to stories about poltergeists. Nevertheless, mysticism has nothing to do with it, and communicate with the spirits of the noise in the pipes will not save.
When the drone to look for coolant leaks. First of all, a thorough inspection of your property, then all the neighboring apartments. If all is dry, the search continues in the cellar. A cloud of steam, pool or whistle will help determine a place where water flows easily. In apartment buildings repair fulfill the management company, in a private house - the owner of the property. After inspection of the problem area is decided by the method of the fault - the repair or replacement of the unit, sometimes just enough to tighten the valve is not closed.
Another reason may be use din a pipe diameter smaller than the heating system calculation. In this case, the problem areas defined by ear, and the required pipe section is replaced with material of greater permeability. With proper selection of pipes and quality performance will not have to listen to the buzzing of the pipe.
Wildness, pops and clicks
Particles of debris, sludge or scale may peel off while moving through the pipes to beat the wall and rub against them, creating noise in the form of cod or churning. Characteristic sound when clogged is also clicked. To eliminate this kind of noise the same flushing system.
Foreign objects in the pipes will be snapping up until not come out. Therefore, the system merges all the liquid through the drain cock. Using the old coolant hose with debris directed into the sewer system further washed with water (steel pipe obstukivayutsya outside wooden mallet for detachment from the inside walls of the scale), after which the heating circuit is filled again.
Important! Before draining the dirty water is better to dismantle the drain valve to allow large fragments of debris to go outside and do not clog them closure.
Quite often, tube cracking and flipped due to a malfunction of the valve or the installation is not on its direction of flow. Through hole curved easily clogged, and it plug can be formed in due course, completely overlaps the coolant movement. Partial overlap of the luminal debris tube generates noise when the water passage. If the valve is on the contrary, the liquid in it comes not from the underside of the locking disc, and the top, which leads to the destruction of the stem and the valve gap. In this case, the movement of the coolant will also be noisy.
The most rational way out - the replacement of the valve, since it is already partially worn in the wrong position, and therefore unpredictable after remounting. For lack of a new node, you can temporarily set the old, replacing the material seal threaded connections.
Council: Choosing a new shut-off and control valves, it is necessary to bear in mind that the ball (cork) Load more practical operation, can be installed in any direction, and not sensitive to clogging, as screw valves.
If the tight closing shut-off valve, it can also be a source of noise. This is normal and is eliminated by its priotkryvaniya or fully closed. Noise can also valves with thermostatic heads, if exposed to them is close to the actual temperature in the room. In this case, the input to the radiator is blocked not to end, and heat transfer medium passes through a small hole with a characteristic sound. To get rid of the noise, simply rotate the head in the direction of the sprocket.
Purling, whistling
When air accumulation becomes hear murmurs water in heating pipes - a very common phenomenon. Air can enter the system during repair work, loose connections sucked through - air lock, regardless of origin, it interferes with the normal circulation of the coolant. Not only is the water while rushing tiresome, so still and the heater does not heat up properly. In the case of formation of air pockets overlapping lumen tube completely after radiators problematic portion of the conduit remain cold.
The air accumulates in the upper always points in the system, as it is lighter than water. It is there that are typically installed special valves or automatic air collectors. Radiators, located at the end of the horizontal branches, necessarily equipped with a bleed screw. In some types of systems, each heater has a so-called "air vent". Nodes modern designs are easily rotated by hand, managing older will have to be carried out with the help of a wrench or screwdriver.
The first step is to try to bleed the air from the radiators of his apartment. The operation begins with the coldest of the device, if any. Often it is the local air pockets preventing heat. If it fails, it is necessary to ask the neighbors from the top floor to find at the corresponding valve and open it. In difficult situations it is better to call a qualified plumber. Indicator of success - the air outlet is a characteristic whistle.
Council: To avoid getting burned open Majewski need to tap gently, being careful - hot water in the system is under pressure. Further, for collecting water which will flow out of the radiator, it is necessary previously to prepare a sufficient volume capacity with a wide neck.
Knock, rattle
Cause knocking is typically a loose pipe bracket or the radiator. The slightest vibration during the passage of coolant through such node causes rattling, and with strong beats radiator supports looseness of fasteners. The system will stop making noise by ensuring rigid fixing brackets. To reduce vibration can be installed between the appliance and the support of the heat-resistant rubber gasket.
Sometimes knocking it may be caused by too close proximity or overlapping of parallel tubes. When the temperature deformations of one pipeline starts to touch another beat of it and becomes a source of noise. The situation can save sound insulation, if the existing gap enough to place it. Otherwise, to eliminate the knocking will have to shift the problem area.
In some instances, a knock on the heating pipes in apartment buildings is caused by dissatisfaction with the neighbors. This type of noise is usually characterized by the absence of periodicity and occurs as a reaction to these or other precipitating action. That's just "enjoy" specific sounds have to all the inhabitants of the riser. Here technical measures do not help, sound can be saved only partially. Conflicts with its neighbors can only be solved through dialogue and diplomacy.
Expert advice on the prevention of the appearance of the heating circuit unwanted sounds
The probability of occurrence of noise in the heating pipes can be reduced by adhering to the following recommendations of the professionals:
- welding polypropylene tube strictly follow the heating of the parts, since overheating It gives a reduction of the working lumen, and subcooling - low connection reliability and a high probability leakage;
- perform bending metal pipes using bending tool to avoid reducing the diameter of the pipe on the bending portion;
- heating circuit pipe must be fitted with heat and sound insulation;
- welding metal electrodisplacive need to use only qualitative electrodes corresponding mark;
- in the upper heating points on the last and devices necessary to have each branch Majewski valves for venting;
- Valves and filters must be installed only in accordance with said direction of flow;
- the pump power must conform to a specific desired system;
- radiators avoid their airing be installed horizontally - by using the bubble or laser level;
system monitoring bimetallic radiator using a spirit level - debris from entering the heating system piping, welding drops, etc. It is not permissible;
- to switch on the pump when using less noisy, it needs to be installed on the expansion joints and equipped with sound enclosure;
- in autonomous heating systems it is important to monitor the status of pumps, as the slightest failure significantly increases the level of noise coming from them; rid of bumps and clicks can sometimes change the mode of operation of the pump;
- use only high-quality sanitary ware, accessories and auxiliary materials significantly reduces the risk of extraneous noise;
- necessary to carry out periodic flushing, preventing a decrease in the working lumen of the pipe due to different kinds of sediments and the consequent emergence of unpleasant sounds.
Important! Finding the source of noise can help dry stick (shank shovels), one end of which is tightly pressed against the ear, and the other - to the elements of alternately heating system. In problem areas the noise manifest itself louder and clearer.
conclusion
In this article, at the household level considered: what if the noisy heating pipes? The first and most important step is to determine the source of the location. You then need to objectively assess their strength and possible consequences of the attempt to liquidate the failure to decide whether to do troubleshooting immediately or postpone repairs until the end of the heating season.
Part of the problem in the heating operation can be eliminated by their own hands, but in severe cases can not do without specialists. In apartment buildings solution to the problem is better to entrust public services, not forgetting to control their actions. Timely response to the noise in the pipes, you will save your health and nerves, as well as the heating system will save from more serious injuries.
