Knocking in radiators in a private house. Why do radiators click in a private house? Causes of noise in the heating radiator
Knocking in the heating pipes of a private house is a common occurrence for an owner with individual heating. Why noise occurs and what affects them - you need to understand.
The main indicator of trouble is a low-quality coolant containing dissolved salts and mechanical impurities.
Causes of noise
There are actually not so many reasons for the appearance of knocking in heating pipes during heating. Part of the noise can be ignored - they do not harm the system and heaters. But such noises as buzzing, crackling, knocking, gurgling, howling should give reason to think and take urgent measures.
Common causes:
- air jams in the system;
- clogging or overgrowth of pipes due to poor-quality coolant;
- leaks in the pipeline;
- violation of installation work during the installation of cranes, valves and pipe laying;
- failure or deterioration of working equipment;
- cavitation, increase in pressure in places of increase (decrease) in the diameter of pipes;
- incorrect calculation or non-compliance with design recommendations when installing the heating system.
These circumstances arise in private closed circuit systems and make us think about their urgent elimination.
The circulation pump in the heating circuit system contributes to the forced movement of water, which leads to uniform heating and the expulsion of accumulated air from the system.
If the heating in the house or apartment is connected to the central pipeline, then starting, accompanied by such sounds, is normal. Water, filling the common system, pushes out air, and, overflowing along the contour, is accompanied by a murmur, knock and crackle.
As soon as the equipment enters the operating mode, the general adjustment of the system will end - the temperature of the batteries will increase, and everything will stop. This is clearly seen in the scheme of heat supply to consumers from the central boiler house.
Types of noise in pipes
The noises accompanying the general start-up of heating differ from emergency ones - they are intermittent and are accompanied by murmuring or gurgling. In bimetallic or aluminum batteries, crackling or buzzing can be heard - this is also normal.
It is clear that prolonged noise is an unpleasant matter, so it is necessary to warn the situation in a timely manner.
The knock and rumble that occur in the room with increasing force give reason to be wary and take drastic measures:
- Check heaters and temperature in the circuit. If a pump is installed, then its operation.
- Pay attention to the valves - if they break, a characteristic whistle appears. Sometimes a small adjustment is enough to make the equipment work.
- Having found visible problems, it is necessary to stop the coolant and turn off the heating devices. After evaluating the breakdown, proceed to eliminate the accident yourself or invite a specialist.
These are the primary measures that can prevent the development of major damage.
Sounds in heaters
If a howl is heard in the middle of the night, then most likely the system has leaked. A cloud of steam and a characteristic whistle will immediately indicate a rush or a failed valve. In some cases, it is enough to close the tap to bring the heating system into working condition.
If no obvious reasons were found, and the howl began to be accompanied by a crack, pressure needs to be checked. Perhaps the flying scale blocked the free th coolant flow, which caused the increased pressure - it is urgent to stop the boiler, drain the water and look for the problem.
It happens that the batteries start to "shoot" - this is another reason to be wary. Such noises are typical for bimetallic batteries when the pressure in the system does not match the calculated one.
Purchasing heating appliances it is necessary to take into account the operating parameters of the boiler and select the appropriate radiant ora. Otherwise, the problem may result in a rupture of the heater from a water hammer, which is completely inopportune in the winter cold.
Heated water is not able to compress, it must move freely along the contour. Banal deposits in pipes can provoke an increase in pressure and rupture of pipes from water hammer.
Another reason is the air lock, which can be eliminated through Mayevsky's drain valves located at the ends of the batteries. The procedure is simple, and everyone can cope with it.
Noise in the pump
A common cause of problems is the operation of the pump. Usually it has three positions for raising the water column to a certain height, which depends on the power of the device. Uniform movement of the coolant along the thermal circuit is not accompanied by noise effects.
Hearing incomprehensible sounds, more reminiscent of mechanical ones, it is worth checking the operation of the pump.
In case of failure:
- a hum appears;
- cracking is possible;
- the boiler begins to make noise and knock.
In this case must be turned off asos, and if the sounds have stopped, then the cause has been found. Crack and noise are mechanical damage: it means that graphite plain bearings have worn out or dirt has got into the housing.
Scale settles on the inner walls of the pump due to poor-quality coolant and acts destructively on its components.
It's easy to check:
- it is enough to remove the pump;
- lower its working part into a container of water;
- when turned on, it must pump water, if this does not happen, it must be repaired.
Important! The pump must not be turned on without water.
Extraneous sounds in the heating boiler
Sometimes the kindling of the boiler is also accompanied by some sounds. When cold equipment heats up and starts to crack, then characteristic clicks should not cause panic - the metal makes such sounds when it is heated.
Gurgling and murmuring are also possible - also a normal phenomenon: the coolant began to heat up and set the system in motion. However, the same sounds can occur when there is not enough coolant in the pipes. In this situation, it is enough to add water so that the heating becomes uniform.
Cotton
You can hear such sounds in case of clogging of the gas outlet pipes. This happens when the boiler is ignited: the accumulated gas, not having time to go outside, creates cotton. This is dangerous, as a sudden burst of flame can cause burns or ignition.
If the boiler is gas, then the causes of such noise are clogged nozzles or a malfunction of the three-way valve. In this situation, it is necessary to clean the equipment from soot.
Knock
The occurrence of knocking in the boiler indicates its improper installation or unregulated operation of pumping equipment. If the pump works unevenly, moving the coolant in jerks, resonance occurs between the boiler and the pump, accompanied by a characteristic knock. In this case, it is necessary to regulate the operation of the pump.
Sounds in different models of boilers
Noise can occur for a banal reason, which lies in the boiler model itself. This is typical for I gas boilers equipped with ventilation burners. To avoid such a nuisance, it is necessary to choose boilers with atmospheric burners and an electronic control system.
When choosing a model of a solid fuel or electric boiler for heating a house, always you need to get acquainted with equipment specifications. Often the cause of noise can be improperly selected equipment, as well as the presence of a fan in the boiler.
Double-circuit boilers also sin with noisy work: although not obviously, the overflows of water and the filling of the system are always accompanied by sounds.
Boilers ZOTA are very sensitive to the quality of the coolant, so the cause of unpleasant effects can be:
- clogged mud tank;
- oxygenated water;
- scale on working elements;
- broken bearings on the fan.
Therefore, it is worth stopping the choice on single-circuit models, and purchasing a boiler to heat hot water.

Prevention
Timely preventive maintenance of all components of boiler equipment can minimize the likelihood of noise.
So, flushing the system once a year is a prerequisite for trouble-free operation. Moreover, this becomes a mandatory requirement of many resource-supplying organizations in preparation for the heating season.
You can flush the system yourself or use the services of specialists.
Depending on the coolant, the type of cleaning is selected:
- Washing with water under pressure generated by the compressor. Sometimes this is enough.
- When deposits on the pipes of iron oxides, appropriate chemicals are used. They eliminate the problem and additionally create a protective barrier against further exposure to an aggressive environment.
- You can use the services of a specialized organization that has the equipment and means to perform the work.
Each operating manual for heating equipment recommends a preventive inspection and cleaning of the working parts of the boiler from corrosion and all kinds of contaminants with partial disassembly - at least once a year. Failure to perform maintenance will void the manufacturer's warranty.
How to remove an airlock with your own hands
Air in the system after a long shutdown is normal. This problem arises not only in the private sector, but also in apartment buildings. Solving it is pretty easy.
Heating radiators are equipped with Mayevsky cranes located at the ends of the batteries. It can be a valve or a fitting with a notch for a screwdriver.
How to fix:
- armed with a small container (for draining water), you need to unscrew the tap and let the air out;
- actions should be performed carefully so as not to get burned by the escaping steam;
- when water comes out of the hole, the valve is closed;
- such manipulations are carried out on each battery.
This eliminates noise and makes it possible to freely move the coolant through the system, evenly giving off heat.
Methods for cleaning radiators from dirt
During the operation of the heating system, dirt accumulates in it: iron oxides, dissolved salts and possible mechanical impurities. But if water moves at high speed through the pipes, then the process slows down in the radiators and the sedimentation of suspensions increases. Therefore, cleaning the radiators is a must.
There are two ways: joint flushing of the entire system and disconnection of the batteries with cleaning using a compressor unit . The batteries create favorable conditions for the accumulation of dirt, as the coolant slows down the movement in them. For flushing, the radiator is attached to the compressor, and it is cleaned of dirt with a pressure of water.
If you carry out annual preventive maintenance of the entire system, then drastic measures will not be required. It is quite possible to confine ourselves to a general flushing of the entire heating circuit with ordinary water. Chemical reagents are used in cases where the coolant does not meet the established parameters and significant deposits of salts and scale appear on the working elements.
After applying chemistry, leaks can form in radiators and cracks can be found that were safely covered with dirt.
To avoid an emergency, before starting the system, all equipment must be checked for operability.
Timely prevention of all components of the heating system will save it from complex accidents and save the budget. learn from the link.
Living in multi-storey buildings, many residents hear extraneous clicks, buzzing in the heating system. This is due to violations of the rules of operation and installation.
Heating pipes are made of steel, which conducts sound waves well. The round shape of the pipes also does not prevent this.
Noises from heating pipes vary. It could be:
- crackling;
- periodic clicks;
- knock.
All extraneous noises reduce the comfort of living, and also often cause leaks and accidents. Why heating pipes knock, you will find out by reading this article to the end.
How to deal with the rumble in the pipes
The hum in the heating pipes occurs for a number of reasons:
- During operation, the diameter of the pipes decreases.
- Water leak.
- Installation of pipes of smaller diameter.
If the heating pipes are buzzing, the first thing to do is look for a water leak. It's most likely in the basement. It is easy to detect by a cloud of steam and a trickle of water.
Call a plumber to fix the leak. The hum in the pipes must stop.
Reducing the diameter of the heating pipe is another reason for the hum in the pipes. You can detect the place of noise by ear. Walk along the pipes and try to find the cause of the noise. As a rule, the source of the hum is in the basement, where the pressure in the pipes is greater than in apartments.
The narrowing of the diameter of the heating pipes can occur for the following reasons:
- Faulty and incorrectly installed shut-off valves, which do not guarantee the protection of the system from the ingress of rust, slag or foreign small particles.
- The formation of plaque inside the pipes, which reduces the diameter of the pipes, as a result of which, the pressure in them increases.
The hum is eliminated by replacing old pipes and valves with ball valves, in which such problems almost do not arise. You can open a water discharge valve located above the expected constriction. Foreign particles, if there are any in the pipe, will exit the heating system.
The water in the batteries boils and clicks
Such noises occur in an air-conditioned heating system, and they can also be caused by debris particles that have entered the system after its repair.
Air is removed from the system using a Mayevsky valve, through which air is discharged from the heating system.
If after that, the noise does not stop, then the possible reason is the incorrect installation of the pipes connected to the heating radiator. A slight distortion can cause unpleasant sounds.
Cracks and clicks can be caused by the presence of debris in the radiators, a broken vent valve. Open the faucet and drain the water, particles may come out of the heating pipes.
Knocking in the pipes
A break in the ventilation valve can cause knocking in the heating system. This happens when the installation is incorrect. If the valve is installed in the opposite direction, then the resulting erosion will lead to its breakage, as a result, there will be a knock in the heating pipe.
A broken vent valve is a serious accident. A sharp increase in water pressure can lead to ruptures in the pipes of the heating system. The riser urgently needs to be blocked and a plumber called. After the repair, the knock should stop.
Extraneous noise may occur due to changes in water temperature. Everyone knows that when heated, metal objects expand and contract when cooled. If the brackets that hold the pipes are not installed properly, they can cause knocking. When the temperature fluctuates, they will move and knock on the steel heating pipes.
If you live in an old building, then this is the most common cause of knocking. It is necessary to go and check the mounting brackets, if necessary, carry out repairs.
Service providers claim that the temperature of radiators and pipes is constant, but this is not entirely true. It often happens that hot water flows through the heating pipes, and then cooled down. An open window in the apartment can cause a short knock in the pipes.
In the entrances of your houses, you often see open windows, broken glass, and all this leads to temperature fluctuations in the heating system, which means knocking in it.
If the brackets are loosely fixed, but pressed against the wall, there will be no knocking, an unpleasant creaking sound will appear.
Having studied the causes of noise in the heating system, we can draw a unifying conclusion - the reason is in old pipes and radiators. It is possible to eliminate them all at once only by making a high-quality overhaul of the entire heating system of a house or entrance. But you can wait a very long time and not wait. Therefore, in the summer, apartment owners should inspect the heating system and fix minor problems.
Almost every one of us has ever encountered a situation where heating pipes knock. Consider the most common and frequently occurring causes of knocking in heating pipes.
Hum or whistle in the pipes: identify the causes
Residents of apartments, especially apartment buildings, complain about the hum or whistle in the batteries quite often. This kind of noise occurs either due to a leak in the communication, or due to a narrowing that prevents the proper circulation of water.
In the event of a water leak, the first step is to visually check all areas of the house. If everything is in order with the neighbors in the riser, then you need to go down to the basement. The first sign of a leak in the basement will be steam. If available, check the entire room. Common leak points are valves or vents in horizontal wiring elements.
Often the latter can be hidden under a layer of thermal insulation. It is also necessary to check the elevator assembly, where a vent can be opened, which drains water from the heating system into the sewer. In addition, we note that the place of leakage is not always located in the immediate vicinity of the source of noise - the sound through the pipes propagates over long distances.
If a visual inspection was carried out, no leaks were found, but you still have heating pipes knocking, it is necessary to check the entire heating circuit for a decrease in pipe patency. The most common sources of noise in multi-apartment buildings are elevator nodes and beds, where slowing down the flow of water leads to noise. Quite often, problem areas are identified by ear when walking around the premises.
Half-closed valves, as well as screw valves with valve defects, can create an obstacle to the flow of water. In addition to valves, crackling in heating pipes can be associated with pieces of slag or scale in the pipeline. In the first case, it is necessary to check the functionality of the valves, if necessary, change them, and in the second, to clean the system, which sometimes requires additional help from the welder.
In severe frosts, it is better to postpone such work until the spring. Nowadays, when designing a heating circuit, it is better to use ball valves that block the flow of the coolant when rotated 90 degrees, and you can forever forget about the valve coming off if it is installed incorrectly.
Bubbling in the radiator
Air in pipes is often the cause of continuous seething or gurgling in radiators. It is possible to bleed the air from the heating system thanks to the Mayevsky tap, which can be located either on the radiator or directly on the pipeline connecting adjacent rooms (in houses with bottom bottling). In other cases, it is necessary to check the communications for the presence of a counterslope.
Skewed radiator or part of the wiring to it can contribute to air stagnation. In the latter case, it is necessary to completely block all communication, which is recommended to be done in the spring-summer season.
Knocking in heaters
A fairly common problem is periodic clicks. The occurrence of this type of noise can be triggered by debris in the riser or radiator, a torn off valve valve, or due to thermal expansion of the riser or battery against the background of temperature instability. If it is garbage, then pieces of slag in the heating rotate in the stream of water, tapping on the walls.
To eliminate unpleasant sounds, it is necessary to flush the pipeline. If draining the water did not bring the desired result, then after the end of the heating season, it is necessary to dismantle and disassemble the radiator or change it.
If the house has a heating circuit with screw valves and pipes click, then first of all it is necessary to check the valve valves. If installed incorrectly, the flow of water can erode the valve, which sooner or later partially or completely opens. As a result, the flow of water can periodically overlap for a moment, creating a water hammer.
Clicks and bumps in the pipeline can be associated with the latter. In this case, turn off the coolant supply for a short time and replace the faulty valve.
In the event of thermal expansion, a periodic soft knock will be heard. This effect occurs due to temperature changes - when it rises, any object expands, and when it decreases, it narrows. In our case, such a physical effect can provoke a slight movement in space (literally up to several millimeters) of the unfixed end of the heating system.
If the moving part of the pipeline is tightly pressed against something, then you can hear a creak, and in some cases crack or clicks. When solving this problem, check the thermal insulation of the pipeline, as well as inspect the battery attachment points, and, if necessary, lay fluoroplastic gaskets.
It happens that after installation, heaters and radiators crack and click. What is the cause of extraneous noise during operation?
Causes of noise in the heating radiator
The cause of knocking and noise in batteries is mainly due to violations made during installation. The most common problems are:- Different diameter of the radiator inlet and piping. Modern systems use control valves, a Mayevsky crane, a bypass, etc. All pipes and shut-off valves must have the same internal section.
- No differential pressure regulator. A special washer is installed in front of the regulator nozzle in the basement of an apartment building, designed to stabilize the pressure. If there is no washer, the coolant makes noise in the batteries when the pressure in the pipeline reaches more than 1.5 bar.
- Heating batteries crackle due to incorrect connection of the thermal valve or poor mounting on the brackets. You can fix the problem by replacing the temperature controller. Water squeezes the valve in the thermostat, which leads to extraneous noise. Cod is also caused by insufficient fixation on the brackets. When heated, the metal from which the radiators are made expands, which leads to noise.
- Air locks - if water gurgles in the radiator, this indicates the presence of air in the system. When the water passes the location of the cork, a sound is made similar to the murmur of a stream. A similar problem is detected if the batteries gurgle when the heating is turned on. The situation is corrected with the help of Mayevsky's crane. By bleeding air from the heating system, you can achieve silent operation.
- Leak in the system. Whistling and buzzing indicates a lack of tightness in the heating system or an excessive narrowing of the pipeline. Moreover, the heating battery is buzzing due to the "fistula" in the riser, not only in the apartment itself, but also in the basement. If a visual inspection does not reveal a break, house management plumbers are called in to look for a pipe break in the basement.
These are the most common causes of noise during heating operation. To determine what became the catalyst for violations, the location and localization of knocking, gurgling or other sounds should be established. After that, identify errors in the installation.
Eliminating noise in radiators is much more difficult than preventing their occurrence. Therefore, it is recommended that the installation of the system be carried out by a qualified installation team.
Why does the heater crackle during operation
The causes of noise in electric heaters, unlike radiators connected to a liquid heating system, are rarely associated with installation errors. The main cause of clicks, crackles and other sounds are violations of operation by the owners themselves.- Oil radiator– if clicks are heard when the heater is turned on, the problem is related to the ingress of moisture into the oil. This happens for several reasons. During transportation, the heater was turned upside down. They transported the heater in the winter, and then immediately plugged it into the network, etc. Detailed instructions on how to avoid unpleasant noise can be found in the heater manual.
- Fan heater and convector– Noises indicate accumulated dust. The heating process is associated with the use of an incandescent filament. The settled dust causes unpleasant clicks during operation, usually accompanied by a burning smell.
Qualified specialists should eliminate the causes of crackling and clicks in radiators and electric heaters. Regarding the malfunction of the electrical equipment, you should contact the service center. A competent plumber can eliminate violations due to which batteries knock, make noise, creak during heating.
