Why are water and heating pipes humming?

Why are the batteries buzzing?

Nobody can definitely tell you why the water in the radiators of multi-storey buildings or private households makes noise, making a hum, a whistle or a constant hum. There are a huge number of reasons, but let’s look at the main ones.

If your home's hydraulics are not properly balanced, annoying noises can occur. All houses that are connected to the central heating main are connected to each other. For normal distribution of coolant, balancing valves of different diameters are selected and throttling nuts are installed at the entrance to each house.

When technicians select the wrong nut or adjust the valve incorrectly, the coolant does not reach the top floors and travels through the pipes very quickly. The accelerated circulation causes sounds similar to the hum coming from batteries. Why else can water make noise in radiators? Read on.

When renovation work is carried out on the technical floor of an apartment building, problems may arise. The humming noise can be caused by increasing the number of pipe transitions without balancing the hydraulics or by using smaller diameter pipes. The solution in this case is to call a plumber, who must resolve the issue at a professional level. Each case is individual, but most often the situation is solved by installing a new balancing valve in front of the risers.

If you don't know what causes water noise in batteries, it may be you. For example, you tried to regulate the coolant inlet into the apartment yourself using a balancing valve. This should be done by specialists. To correct the situation, you need to change the adjustment or call a technician who will quickly cope with the task.

Types of extraneous sounds in the heating pipeline

Under the influence of various factors, noise can appear not only in batteries, but also in heating pipes. At the same time, both metal and metal-plastic pipes can sound equally unpleasant.

Extraneous sounds in the heating pipeline may appear:

• Murmuring.
• Rattling.
• Crackling.
• Clicks.
• Gurgling.
• Noise.
• Howling.
• Whistling.
• With a knock.

Often such noises indicate serious problems in the heating system, which require timely diagnosis and elimination.

The pipes howl and hum

The most common type of noise is when pipes suddenly begin to hum, this is especially noticeable at night. The probable cause of the buzzing and howling is a coolant leak. To identify the source of the leak, each apartment is carefully checked for its riser, as well as the basement. In a private house - any room in which a heating radiator and boiler room are installed.

If a malfunction is detected in the operation of the system in an apartment building, residents have the right to complain to the management company or condominium association for repair work. In a private house, repairs to the system are carried out at the expense of the home owner.

Another reason for humming may be the different diameters of the pipes that were used to organize the pipeline. In such a case, the problem area is replaced with a larger diameter pipe.

Clicking, crackling and bubbling in pipes

In most cases, blockage with small particles of debris or sludge leads to cracking and clicking sounds in the pipes. A characteristic sign of clogging is also a dull click.

To ensure that the pipeline stops clicking, the system is thoroughly flushed. To do this, the coolant is completely drained through the drain valve into the sewer, and the pipeline and heating circuit are washed with clean water.

An equally serious cause of cracking and clicking is a broken valve or its incorrect installation. The simplest solution is to install a new device. To prevent a similar problem in the future, it is recommended to use ball valves, which are characterized by increased strength and resistance to blockages.

The pipes gurgle and whistle

Often, when there are air pockets, the pipes whistle, and the coolant in the system begins to make a characteristic murmur. Air can enter the heating circuit and pipes during repairs through leaky connecting elements. In addition to the constant babbling of water, there may be insufficient heating of the heating equipment to maintain the optimal temperature in the room.

The problem is solved by bleeding excess air from the heating system through the Mayevsky tap. The hot coolant is supplied under high pressure, so water is collected in a prepared container in small portions.

Pipes knock and rattle

The cause of knocking in the heating system may be insufficient fixation of fasteners for pipes or radiators. The passage of coolant through the system can cause even slight vibrations, which lead to rattling and knocking. The problem is solved by ensuring rigid fixation of supports for all elements of the system in each individual room.

Sometimes pipes rattle and knock if they are located close to each other. Thermal expansion of metal leads to friction of surfaces that can make unpleasant sounds. To eliminate knocking, it is enough to soundproof the problem section of the pipe.

Other sources of extraneous sounds in the heating pipeline

In addition to violating the installation technology of the heating system, the horizontal pipeline and riser are noisy for the following reasons:

• Water hammer.
• Low quality coolant.
• Noisy operation of pumping equipment.
• Wear or deformation of individual system elements.
• Violation of tightness and permeability.

To identify significant problems, professional diagnostics will be required.

Having figured out the reasons why heating radiators make noise in a multi-story and private house, you can apply simple and effective ways to eliminate them. For example, reduce the pressure in the system, remove air pockets, replace pipes of the required diameter or a thermal valve. Complex cases require an integrated approach to diagnosis and problem solving by experienced specialists.

What to do if water gurgles in the heating system of a private home?

Nowadays, megacities have become places that attract quite a lot of people from all cities of Russia. But at the same time, there is a tendency for residents of cities such as St. Petersburg to move to the suburbs or villages. Following this trend, the entire Leningrad region is dotted with private houses, which in turn are used as dachas. In this article we will discuss the nuances of the heating system, as well as the basic principles of its operation. We will also deal with many problems that arise during the operation of the heating system, we will also talk about this, and in great detail.

Features of choosing a heating system

The heating system in each house is selected individually and in this case a lot depends on the following factors:

• Area of ​​your home
• Number of floors in the house
• The degree of insulation of the house
• Climate
• Number of doors and windows
• Type of available fuel

Among these features, it is worth highlighting the last point, because it is on this basis that the boiler in the system is selected. There are 2 types of heating systems themselves, these are:

• Water heating
• Air heating

In this material we will dwell in more detail on water heating, since it is now the most popular type of heating systems in Russia.

Water heating elements

Water heating functions thanks to the interaction of these elements:

• Boiler
• Pipeline
• Pump
• Coolant
• Radiators

These elements allow the water heating system to perform its direct functions. Now it’s no secret that water heating has this name due to the fact that water acts as a coolant. This is a very versatile type of coolant that does not require the installation of additional equipment, but at the same time requires constant care so that the water does not freeze during sub-zero temperatures. Naturally, if one of the above elements fails, the system cannot operate normally, performing its direct functions. We will talk about such problems or other types of problems further.

Problems with gurgling water in the system

The problem when water begins to gurgle in the heating system is a fairly common occurrence. Many owners of private houses have already encountered this and do not know what to do. Do not rush to call the emergency service or release water from the circuit. It’s worth saying right away that this problem is often associated with the fact that there is a certain amount of air inside the pipeline. The air itself often gets into the coolant for the following reasons:

• The problem is insufficient tightness of the connections. To prevent this from happening, you need to carefully check all connections for any slight damage.
• Before starting the system and pumping coolant, air was poorly removed from the coolant itself, which causes the system to gurgle in the future.
• The heating system was not installed correctly, especially for older systems.

Coolant circulation speed

Sometimes, the cause of gurgling in the system may not be due to the fact that there is air there. This can also be caused by the high rate of coolant circulation in the system. This problem occurs most often in apartment buildings when central heating is installed. To eliminate this type of system gurgling problem, you must contact the housing department with a specific request. In other cases, it is necessary to remove air from the pipeline, as well as check the slopes of the pipeline system, which must comply with all standards.

The principle of operation of heating batteries

Residents of apartment buildings rarely think about the principle on which modern batteries operate. And only with the appearance of specific sounds signaling problems in the heating system does the question become relevant.

The operating principle of the radiator is as follows:

1. The heating circuit is filled with coolant - water.
2. The coolant moves through the system and ensures heating of all its structural elements.
3. A heating radiator easily accumulates thermal energy that it releases into the room.
4. The cooled coolant is returned to the common riser and the heating cycle is repeated.

The movement of the coolant begins from the general boiler room or autonomous heating equipment (boiler) through the pipeline to the radiators.

It is not surprising that in a certain area the movement of the coolant may be accompanied by unpleasant noise and hum.

Modern heating batteries are represented by the following designs:

• Tubular radiators.
• Sectional radiators.
• Panel convectors.
• Plate radiators.

How to solve noise problems

It often happens that the heating device becomes clogged from the inside. In this case, pieces of slag will move along the radiator along with the flow of water, touching the walls.

In this case, flushing will help. A hose is put on the faucet, and the water along with the debris is gradually drained.

Video:

If the procedure does not help, at the end of the heating season the radiator will have to be dismantled, disassembled and cleaned, or replaced.

An air lock in a heating device is a common cause of unpleasant gurgling sounds.

This problem is solved with the help of a Mayevsky crane, which will allow the air to be released and the battery to continue to operate silently.

Quite often, at the beginning of the heating season, problems with noise in pipes can arise due to pressure that is not fully equalized.

When the pressure difference in the pipeline exceeds 1.5 atmospheres, tapping may begin.

In this case, the specialist must install a washer in front of the regulator nozzle, which will equalize the pressure.

In an apartment building, a circulation pump is responsible for the movement of warm water through pipes and heating appliances in apartments.

If for some reason it starts to work incorrectly, then specialists must determine the solution: it may be necessary to install a special valve that will correct the operation of the pump, or it may even go as far as replacing the unit.

If the cause of the noise is identified in the place where the heating battery connects to the bracket, then you should think about replacing the brackets or choose a simpler method - place a rubber pad between the battery and the fastening element to prevent friction.

You can identify the leak yourself. To do this, just inspect the pipes in your apartment or house. If one can be seen with the naked eye, then this is good luck, and corrective measures can be taken immediately.

Having found out that everything is normal in the apartment, you need to go around the neighbors to look for the pipe from which water is leaking.

Video:

If your neighbors also do not find a leaking pipe, then it is necessary to inspect the main unit of the heating system.

In an apartment building, it is located in the basement, going down into which you can immediately come across steam - it is this that signals the location of the breakthrough.

In this case, the emergency service is immediately called.

As it turned out, there are various reasons for the unpleasant sounds emanating from radiators. But it will be easier to find out the reason now.

In most cases, it is better to solve the problem of eliminating noise according to the opinion of specialists, because they are guaranteed to have experience, knowledge, special tools and spare parts.

The main thing is not to hesitate, because this will help to avoid emergency situations in the future.

Methods for finding a faulty tap

To identify an apartment with faulty taps, you need to turn them off one by one from the hot and cold water pipes and listen to whether the unpleasant sound has disappeared or not. As soon as the hum in the pipes stopped, an apartment with faulty plumbing was found.

If you checked each of the apartments in the house using the method described above, and the problem was not solved, it is likely that the sound is caused by the installation of a valve blocking the riser. You can test this hypothesis by turning off the taps supplying water to this riser. If the sound disappears, then the problem lies with the riser valve.

Remember also that if you have a branched water supply system in your basement, containing many valves and valves, any shut-off valves can cause a hum. In this case, determining the cause of unpleasant sounds without an experienced plumber can be very difficult and not as quickly as we would like.

If the cause was still localized, consider yourself lucky. With simple repairs it can be easily eliminated.

Causes of noise in batteries

To determine the reasons why batteries are noisy, it is recommended to check the external condition of the devices. If there are no visual defects or damage to the housing, it is necessary to determine the type of extraneous sounds. Often the sound effect is created when water hisses and makes noise, clogged pipes click and hum, or the radiator housing knocks. This is influenced by the following factors:

1. Mismatch in diameter of water pipes. Often the heating system consists of pipes of different diameters, which can cause unpleasant knocking and noise in the battery when the coolant moves. The problem is solved by replacing pipes of the same diameter.
2. Pressure surges within the system. To reduce the maximum pressure in an apartment building, a special washer is mounted in front of the incoming elevator pipe or a pressure regulator is installed.
3. The appearance of air pockets in the pipeline and heating devices. This causes the coolant to gurgle in the batteries. Residents of a multi-storey or private building can hear a similar sound at the beginning of the heating season when the system is filled with hot coolant. Removal of traffic jams is carried out by draining the water using a Mayevsky tap.
4. Incorrect thermostat installation. Sometimes noise in radiators can occur as a result of incorrect connection of the thermostatic valve. In some cases, batteries crack when the thermostats are installed and not adjusted by neighbors in the riser. To solve the problem, it is enough to check the correct installation and settings of the valve in your own and your neighbor’s home.
5. Displacement of the heating battery. When the coolant heats up, the heating circuit can expand, which leads to involuntary friction of surfaces. If the heating battery clicks, this problem can be eliminated by installing a rubber gasket between the fixing elements and the batteries.
6. Modern multi-storey and private houses are equipped with a circulation pump, the vibration of which reaches the heating circuit. To reduce the noise during pump operation, it is recommended to install a special inlet valve on the elevator.
7. Heating circuit clogged. If the battery crackles and hisses, this may be due to the entry of small particles of debris with the coolant into the system when the heating main breaks. To remove the unpleasant consequences of blockages, a complete flushing of the heating system is required.
8. Sudden temperature changes when heating the coolant. If the heating circuit is filled with hot coolant and then cool, a characteristic sound may occur due to the clicking of the battery housing. This occurs as a result of thermal expansion of the metal.

Causes of noise

The reasons why water gurgles in heating pipes are the following factors:

• Installation errors. Different diameters of the heating circuit, a large number of line turns, incorrectly selected or installed shut-off valves, air vents often cause humming or knocking.
• Poorly secured fittings, pipelines or close proximity (contact) of pipes can cause noise as a result of its vibrations. The main method of eliminating the problem is to rework the incorrectly installed section of the pipeline, securely fixing the pipes and fittings.
• Leaks. Whistling or hissing noise in the heating system of both an apartment building and an individual building is often caused by coolant leaks. Liquid usually leaks from pipeline joints, leaky gaskets of shut-off and control valves - ball valves, air vents, thermostats. The malfunction can be easily detected by the sound and the appearance of puddles; the simplest method of eliminating it is to use overhead clamps on the pipes and replace the gaskets, winding sealing flax fibers, FUM tapes at the joints and in the fittings.
• Airing. The increased air content in the coolant and plugs during its passage cause various types of sounds of flowing water during the process of bleeding air from the heating circuit.
• Damage to fittings and electric pump. Malfunctions in shut-off ball valves in the form of weakening of their fasteners, wear of the shut-off sphere can cause a decrease in the cross-section of the passage channel and the corresponding appearance of noise. Similar sounds occur when the impeller of the circulation pump does not rotate.
• Presence of scale or foreign deposits in the passage channel. When scale forms in the boiler or on the internal walls of metal pipelines, a knocking sound often occurs due to the temperature difference between the pipe material and the coolant.

How to remove the gurgling and noise of water in batteries

What to do when the noise from the batteries sounds like gurgling and gurgling? There is only one answer in this case - it is an air lock. Air entering the system in different ways causes unpleasant sounds that irritate the owners of an apartment or private house. The reasons causing this include:

• incorrect filling of the heating system with water initially;
• broken pipeline tightness;
• filling the system with untreated water.

In each case, the solution is to bleed the air - the system needs to be de-aired. For this purpose, there are Mayevsky taps, which are opened with a screwdriver or a special key. First, air comes out of the hole, then bubbles. You need to wait for an even stream without interruptions - in this case there is no air in the system.

Sounds from heating devices

If you hear a howl 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 gust 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 causes are found, and the howling is accompanied by a crackling sound, it is necessary to check the pressure. Perhaps the flying scale blocked the free flow of the coolant, which caused 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 noise is typical for bimetallic batteries when the pressure in the system does not coincide with the calculated one.

When purchasing heating appliances, you need to take into account the operating parameters of the boiler and select the appropriate radiators. Otherwise, the problem may result in a rupture of the heating device due to water hammer, which is completely inappropriate in the winter cold.

Heated water is not able to compress; it needs to move freely along the contour. Banal deposits in pipes can provoke an increase in pressure and rupture of pipes due to water hammer.

Another reason is an air lock, which can be eliminated through the Mayevsky drain valves located at the ends of the batteries. The procedure is simple, and anyone can handle it.

Noises in the heating pipe

There are also two reasons for noise in a heating pipe - a narrowing of the pipe, which turns into an obstacle to the flow of water, and a leak in the heating system. It is clear that detecting a leak is not difficult. But with the first reason you will have to tinker. It is logical that a narrowing in the riser of the heating system will result in a lower radiator temperature for you than for your neighbors. An obstruction to the flow of hot water can be a screw valve with a faulty valve, a half-open valve, or a piece of scale or slag stuck somewhere across the pipe. It’s easy to deal with a half-open valve yourself, but other issues require the intervention of the management company.

Battery cleaning scheme

Noises in the heating system in the form of knocking can also occur in radiators. There are three reasons for this - thermal expansion at variable radiator temperatures, a broken valve valve, or small particles in the water flow.

I found the source of the noise in the heating pipes!

Let's start small, with the smallest particles of slag, which, when knocked against the walls of the pipe, create extraneous noise. You can try to remove them by flushing the heating system. If there is a flush tap, you can do this yourself; if not, then it is better to call a plumber.

A broken valve is a common problem with all screw valves. Moreover, a damaged valve can completely block the flow of hot water, leaving some apartments without heat. And in the best case, with a slight misalignment, it can chaotically change its position, causing looseness, and from time to time block the lumen of the pipe, thereby causing water hammer. In these cases, the management company must immediately repair the heating system by replacing the damaged valve.

Screw valve

But the neighbor doesn’t know...

And finally, the third reason why pipes in the heating system hum is from a knock in the radiator, which is mounted on steel supports and is located, as a rule, under the window, which we often open to ventilate the room. Opened it - the radiator temperature dropped. They closed it and it went up again.

So, at the slightest movement of the device, as a result of slow expansion and contraction of the metal, creaks will appear, similar to rare tapping. To eliminate them, it will be enough to lay a fluoroplastic plate between the steel support and the contacting surfaces of the heating radiator.

I would like to remind you that noise in water supply and heating systems is only part of the tones in the polyphonic sound palette of a trumpet “symphony”, but we have considered the main ones.

It's good if you don't have to call a plumber about humming in the pipes

On this hopefully optimistic note, I want to end this article about the repair of heating and plumbing systems. I think that after this, everyone can figure out why the pipes are humming and fix the problem with their own golden hands, or with the hands of management companies. Finally, I have a question for you: “Are your upstairs neighbors bothering you with their noise?” Why did I ask this? It’s just that in the next article we’ll look at how to protect yourself from noise from above.

Presence of noise in the heating system pipes

When noise is detected, especially if heating pipes are cracking and there is a hum, the reasons may be complex.

It is quite difficult to immediately understand the sources of sounds, since they can overlap:

1. If there are clicks in the heating pipes, they are often caused by a blockage that has formed in the system. Most likely, the lumen of the pipeline has narrowed and following this, in a separate section of it, the pressure becomes higher, then it drops, and the presence of such a difference makes itself known.
2. In the case when heating pipes crack in a private house, the malfunction is associated with the air valve. It should be checked and, if necessary, replaced with a new product.
3. When the pipe vibrates, then an error was made during installation of the system, and it may hit the wall. If a problem is detected inside the structure, it needs to be flushed to solve it. If the cause of vibration is located outside the pipeline, additional absorbers and fasteners should be installed. If there is a problem with the pumping equipment or mixer, they are either repaired or replaced.

Noise from heating pumps

Constant noise in the heating pump may appear due to partial breakdown of its components - the impeller or rotor. At the same time, the functioning of the entire system deteriorates, which leads to a decrease in its efficiency. To eliminate this reason, the pump should be repaired or a new one installed.

Also, constant noise in the circulation pump can be caused by its unstable operation. Voltage drops lead to loss of synchronization and, as a result, uneven movement of the coolant. This can cause noise in the heating system in other areas - in pipes and radiators. The operation of the pump can only be checked after a complete diagnosis. It is impossible to do it at home without special equipment.

In addition, noise effects in the riser or other areas of the heating supply may occur due to pump malfunction for the following reasons:

• Incorrect installation
  . The rotor of the device must be strictly horizontal;
• Inconsistency of equipment power with calculated data
  . This leads to a significant increase in the rate of coolant flow through the lines. The only way out is to install a pump of appropriate power.

In practice, it is extremely difficult to diagnose noise in a heating circulation pump. To do this, it is necessary to dismantle it and disassemble the structure. This can only be done with special skills and diagnostic tools. Therefore, this work is best left to professional repairmen.

And the neighbors are noisy too

More often than not, it's not just you and your family who suffer this. Therefore, you first need to go around the neighbors along the riser to identify the location of the noise.

Let's find out where the pipes are making noise

Now, as for the nature of the buzz. Heating pipes, like water pipes, can emit single or rhythmic sounds, something like tap dancing, rustling, gurgling, or even generally vibrate and even hum – periodically or constantly. The reasons can be completely different, they are even classified into groups. But now we will not consider absolutely all of them, but will focus only on impact noise effects.

Note: The likelihood of noise in pipes is sharply reduced if you use metal-plastic or plastic pipes instead of metal and copper. This is explained by the high sensitivity of steel pipes to low-frequency vibrations and high rigidity. Although their material is much stronger. It is recommended to use ball valves rather than screw valves as shut-off valves, which are controlled by turning the handle. These are heavy cast copper products, not Chinese-made products made from light alloy material.

How to avoid noise

It is important to turn off the gas before making any repairs. If you suddenly feel that you smell gas, immediately turn off the tap at the entrance to the house, turn off electrical appliances, ventilate and call the gas service

During installation, you can install an elastic vibration-absorbing layer under the casing in all places where the boiler comes into contact with the wall.

Boiler cleaning

First of all, it is important to carry out regular maintenance of heating equipment, which includes cleaning components, removing dust and lubricating some elements. This will increase the lifespan of your boiler and eliminate noise before it even occurs.

In a closed system, you need to add water from time to time, monitoring the pressure gauge. In some devices, for example, Visman Vitopend, it is displayed on the control panel at the bottom of the case.

Let's figure out what to do when the device is already making strange sounds:

If the cause is oxygen saturation of the water, the problem can be solved by converting the open system to a closed one. To do this, air vents are installed on the water heating boiler and the expansion tank is replaced with a membrane one. The fan should be inspected and cleaned

It is important to note that the main blades are located inside the housing under the casing. After cleaning the dust and dirt, additionally lubricate its bearings

If this does not help, the cooler needs to be replaced. When the heat exchanger howls, you need to clean the scale inside it. In order to remove it, the casing is removed and the pipes connected to it are unscrewed. It is best to pour a special anti-scale chemical inside, which is sold in hardware stores, and leave it for several hours. If removing the heat exchanger is too difficult, the product is poured inside using a flexible hose. If the gas valve whistles, you need to check its settings. The correct configuration is written in the operating instructions. When the pump power exceeds the need of the system, it is necessary to reduce its speed by changing the position of the white switch under the cover on the terminal block. Air from the heating system is discharged through a brass air vent on the front panel of the device. If there is a popping noise when igniting on semi-automatic models with piezo ignition, such as Bosch W, clean the nozzle and pilot tube that the starter ignites from dust and clogging. When an automatic boiler, for example Ariston Genius, turns on with a loud bang, you should clean the ignition electrodes and, if necessary, adjust their location. After this, the fire will proceed quietly. Noise from valves can be prevented by replacing them with ball valves or installing an additional rubber gasket. To get rid of the fact that the gas meter is clicking, you need to call the gas service to check it. Most likely, you will have to replace the device. In order to eliminate metallic knocking when the temperature of the radiators changes, you should move the wall mounts to places that coincide with their support points. Putting rubber gaskets on the brackets also solves the problem. When heating pipes built into the wall ring, you need to lay a special insulating material called Merelon around them. It is advisable to think about this at the time of installation, so as not to spoil the repair later.

If it is difficult to localize the sound, let the boiler operate in different modes. For example, if you have a double-circuit device, for example Ferroli Atlas, and you don’t understand what and why it’s humming, turn off the hot water supply. Next, note at what time interval the extraneous sound appears, when the boiler is just starting up or at high temperatures, after it overheats.

Extraneous sounds in the heating boiler

Sometimes the heating of the boiler is also accompanied by some sounds. When cold equipment heats up and begins to crack, the characteristic clicks should not cause panic - metal makes such sounds when it warms up.

Gurgling and gurgling are also possible - this is also a normal phenomenon: the coolant began to heat up and set the system in motion. However, the same sounds can occur if there is insufficient coolant in the pipes. In this situation, it is enough to add water to ensure uniform heating.

Cotton

You can hear such sounds if the gas outlet pipes are clogged. This happens when the boiler is ignited: the accumulated gas, without having time to escape, creates a bang. This is dangerous, as a sudden burst of flame can cause burns or fire.

If the boiler is gas, then the reasons for 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 a knocking sound in the boiler indicates its incorrect installation or unregulated operation of the pumping equipment. If the pump operates unevenly, moving the coolant in jerks, resonance occurs between the boiler and the pump, accompanied by a characteristic knocking sound. In this case, it is necessary to regulate the operation of the pump.

Sounds in different boiler models

Noise can occur for a trivial reason, which lies in the boiler model itself. This is typical for gas boilers equipped with ventilation burners. To avoid such trouble, you need to choose boilers with atmospheric burners and an electronic control system.

When choosing a solid fuel or electric boiler model for heating your home, you should always familiarize yourself with the technical characteristics of the equipment. Often the cause of noise can be incorrectly selected equipment, as well as the presence of a fan in the boiler.

Double-circuit boilers also suffer from noisy operation: although not obvious, water overflows and filling of the system are always accompanied by sounds.

ZOTA boilers are very sensitive to the quality of the coolant, so unpleasant effects can be caused by:

• clogged mud trap;
• oxygenated water;
• scale on working elements;
• Broken bearings on the fan.

Therefore, it is worth choosing single-circuit models and purchasing a boiler to heat hot water.

Prevention

Timely prevention of all components of boiler equipment can minimize the likelihood of noise.

Thus, flushing the system once a year is a prerequisite for trouble-free operation. Moreover, this is becoming a mandatory requirement of many resource supply 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:

1. Washing with water under pressure generated by the compressor. Sometimes this is enough.
2. For iron oxide deposits on pipes, appropriate chemicals are used. They eliminate the problem and additionally create a protective barrier from further exposure to an aggressive environment.
3. You can use the services of a specialized organization that has the equipment and tools to perform the work.

Each operating manual for heating equipment provides a recommendation for 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. If maintenance is not carried out, the manufacturer withdraws its warranty obligations.

The batteries are humming

The reason why heating radiators in a private house or apartment began to gurgle is due to unevenness of the pipes and different cross-sectional diameters. This is due to the fact that water circulating along irregularities and bends encounters obstacles and flows around them. Violation of the fluid permeability indicator provokes the occurrence of gurgling.

Cleaning and washing batteries

In this case, in order to understand why the heating radiators are noisy, you need to get rid of the blockage and check whether the valves are closed and not damaged. If everything is fine with them, use two methods:

1. Cleaning with strong water pressure.
2. Using special chemicals that corrode the garbage. Then it is washed using the first method.

In cases where the blockage has occurred in large quantities and has formed a plug, the help of a welder may be required to clear the debris. Advice. When designing shut-off valves, take into account the possibility of debris ingress and abandon the valve option. Use ball valves only. They are much easier to use and have good wear resistance.

An increased degree of wear and tear of the heating pipes in the apartment also contributes to the appearance of extraneous sounds in the heating system. Check it annually. If it has been determined that the sound comes specifically from the heating radiator, it is necessary to check its condition, and it is better to entrust its replacement to a specialist.

Noise in pipes with a working radiator

There is also an option when the batteries and radiator in the apartment are working properly, but there is still noise when the system is operating. Then you should look for the cause in the basement, where the pipe entry points are located.

You can pay attention to:

1. Possible leaks;
2. Pump operation;
3. Quality of vibration inserts.

Replacement and repair of equipment should be carried out by a professional. But it is within your power to ensure that the system is thoroughly inspected for damage.

Please note: water hammer can cause damage to the heating radiator. Check to see if anyone has recently touched the valves or if the water pressure has been too strong. Finding out the cause of the breakdown will help you fix it faster.
