Types of noise and its diagnosis
If water makes noise in the heating pipes during the operation of the heat supply, then there are certain reasons for the occurrence of this effect. First you need to identify them, and then proceed to reduce noise or completely eliminate it.
Why does water make noise in heating pipes and how to correct this deficiency? Let's deal with the main types of extraneous sounds. They indicate the objective factors for the occurrence of an undesired effect:
- Crack in pipes. Occurs when the heating system is turned on;
- Clicks that appear at regular intervals;
- Constant hum in highways;
- A barely audible knock.
All these extraneous effects - noise in the radiator or radiators significantly reduce the comfort of living in the house. In addition, they may indicate improper operation of the heat supply. If timely action is not taken to correct the situation, any heating element may fail.
If the heating pump or another component of the system is noisy, you should first try to localize the cause of extraneous sounds. To do this, it is recommended to use the following method:
- Track the frequency of occurrence of the effect.
- Try to identify the dependence - temperature increase in pipes, pressure surges, etc.
- Make sure that the noise in the heating boiler comes from it, and not from other objects in the boiler room.
If it was found that the source is a component of the heating system, certain actions should be taken to eliminate this phenomenon.
Appliances are noisy when hot water
Modern boilers operate quietly, so vibration, noise, extraneous sounds should alert you. What can be the indirect cause:
- Incorrect installation, connection.
- Incorrect setting.
- Node wear.
There are very specific reasons why the boiler is buzzing.
High oxygen content
The water in the pipes is supersaturated with oxygen, which is why bubbles are released when heated. This effect leads to increased noise and vibration not only of the device, but also of the batteries.
Air accumulation in the system
If the boiler knocks and puffs, it is necessary to bleed the air in the pipes. Taps are installed on modern radiators. By unscrewing them, you can remove the accumulated air.
Scale formation
A high salt content in water leads to their deposition on the walls of the heat exchanger. Therefore, when heated, the unit will hiss. In addition, the heating rate and heat transfer are reduced. It is recommended to clean the radiator once a year. To do this, a pump with a reagent is prepared, a cleaning liquid is pumped through the hoses.
Fan operation problems
The fan works in models with a closed chamber and forced removal of combustion products. Why does it make strange sounds when it rotates, whistles:
The grease in the bearings has dried up due to placement above the burner. Under the influence of high temperatures, the grease dries quickly, which leads to bearing wear. Parts are disassembled and lubricated.
Imbalance of the blades, accumulation of dirt and dust. The blades are cleaned, adjusted from rotation.
Overpressure in the heating pump
The pump pumps high pressure, you need to adjust its settings. Too high pressure in the system can lead to an emergency. The values can be adjusted by toggling the white lever on the terminal box.
A lack of water in the system leads to serious overheating. First of all, check the thermostat values, set lower values. Measure the pressure, add coolant if necessary.
As well as:
- If the boiler howls, the problem is in the wrong setting of the gas valve or bypass (pipe jumper).
- When operating at high power, the gas meter may rattle.
- A worn valve makes rattling noises.
Why does the heating boiler click. Why the heating boiler is noisy, we understand together
A recently purchased gas boiler operates quietly, barely noticeable to a person. If the unit suddenly starts making noise during operation, this is a direct sign of the appearance of the first malfunctions in the system.
The fan is out of order, the walls of the heat exchanger are clogged with scale, the components of the apparatus are worn out or the boiler is incorrectly configured - all these reasons lead to the fact that the device squeaks, knocks, buzzes or makes clicks.
Why does a gas boiler make noise when heated?
Exists many reasonscausing alarming noise in the gas boiler. Every failure requires a different approach for its elimination.
Faulty fan located above the burner
The fan provides blowing in the system for removal and removal of smoke, and also cleans the residues of gas combustion products. Common Cause fan failure is operating time.The longer the boiler works, the more parts of the system wear out.
Photo 1. It looks like a fan in a gas boiler. Its failure can cause unpleasant noise coming from the heating device.
Other causes of breakdowns:
- fan usually located above the burner. Constantly being exposed to high temperatures, the bearing grease burns out. This causes rapid wear.
- Fan full of dust and residues from gas processing.
- Manufacturing defects.
Reference.There are characteristic sounds that signal a malfunction of the device. Listen to the work of the boiler. If he publishes clicking sounds at short intervals - The reason is the fan.
For to renovatefan, should be manipulated:
- To start inspect fan and clean it from the inside: the main blades are located on the inside of the housing, it is necessary to free them from accumulated dust and dirt, and then lubricate the bearings.
- If the problem persists and the boiler is still noisy, you can replace valves with ball valves or install a rubber gasket.
- If the previous measures did not help, then you should reinstall cooler. To do this, you need to call the master and replace the worn-out device with a new one.
Scale in the heat exchanger
The heat exchanger is a component of the boiler playing the role of an intermediary between the thermal energy of gas and waterwhich is heated by it. Because of it, scale appears and lime collects both on the walls of the radiator pipes and in the entire heating system.

Why does the speaker crackle and click?
Clicking and crackling, another common malfunction of gas flow-through water heating equipment. Breakdown occurs in both automatic and semi-automatic boilers. The following is the nature of the sounds and indicates what exactly can cause them:
- The geyser clicks, but does not ignite - the contacts on the ignition unit are oxidized. The module is not disassembled and needs to be replaced. The catalyst for the fact that the geyser crackles, but does not ignite, can be dead batteries.
- The geyser clicks after the water is turned off - the frog water regulator has failed. Inside the block there is a rod with paws connected to the ignition block. After turning off the water, the spring should return the metal rod to its original position. If the rod is rusted, it may seize. The ignition unit remains on and continues to produce a spark. For this reason, the column cracks after being turned on. A hardened frog membrane can cause a malfunction - it needs to be replaced.
- The piezoelectric element constantly cracks - the contacts are oxidized, which leads to jamming and stable operation.
The noise in the column causes insufficient draft (the flame burns with a hum, changes its color, there is soot), poor air circulation (observed after installing metal-plastic windows in the kitchen), clogging of the burner's ignition wick or overgrowing of the heat exchanger with scale. The malfunction is found by elimination during the next column maintenance.
Why does the gas boiler hum and/or whistle?
There are times when the boiler interferes with its emitted noise. The burner makes a noise similar to that of a jet aircraft. The gas boiler is noisy and can be heard throughout the house. It naturally interferes with sleep, especially turning on after a pause. How to reduce the noise emitted by a gas boiler?
Usually, it is not the boiler and the fan installed in it that make noise, but not the correct installation of the chimney. To make the boiler start to make a noisy sound, it is enough to narrow the chimney a little, and you are provided with a sound like at the airport. The solution is to change or expand the chimney.
There are very frequent cases when gas equipment with pressurized burners starts to buzz. The fact is that the fan units are equipped with a stabilization system aimed at regulating the pressure of the gas supplied to the combustion chamber. During operation, such a boiler buzzes like a vacuum cleaner. To minimize the unpleasant buzz, it is better to build a boiler room building away from a residential building, and make good sound insulation for it.
The boiler may begin to hum due to a thick layer of plaque on the inside of the heat exchanger tube. The boiler begins to boil - it makes a sound like the sound of water from a boiling kettle. Clogged primary heat exchanger. You can check this as follows: set the maximum temperature on the boiler and close the return or supply valve so that there is a minimum water flow. When the temperature reaches about 80 degrees, the hum increases. The only way to solve the problem is to clean the heat exchanger.
Cushioning lining - what is it?
Shock-absorbing lining is a rubber sheet 10-12 mm thick or rubber washers of the same thickness. To reduce noise, all connections must be tight, rigid, the chimney must be additionally insulated with thermal insulation (basalt mineral wool, etc.)
It happens that when the ignition button is pressed, a whistle is heard from the pilot burner nozzle. If air has appeared in the gas pipeline or gas fitting, it is necessary to unscrew the nut at the junction of the gas pipe to the gas fitting, press the ignition button, after loosening the tube, bleed the air that has appeared until the smell of gas appears. Tighten the nut.
If there is a flame separation, then the gas pressure of the pilot burner should be adjusted with the adjusting screw. There are times when the wrong nozzle is installed, then it just needs to be replaced. This situation takes place in domestic units. The nozzle may also have a factory defect, expressed in the absence of a chamfer along the edges of the holes. When switching to an increased intensity mode, the gas flow escapes, and the boiler begins to whistle. The only way out in this case is to replace the nozzle.
We should not forget that gas boilers are explosive, therefore, to correct problems, it is better to contact the specialists of Tyumengazservis LLC by phone 8 3452 58-04-04.
Pops and clicks on ignition
When starting the Ariston boiler or another brand, do you hear knocks and pops? The problem requires an immediate solution.
Three-way valve
The part is used to switch the operation of the unit from heating hot water (DHW) to heating, and vice versa. A faulty valve will click every time it fires up. In this case, it needs to be replaced.
Ignition block
A loud bang occurs when a spark is ignited for a long time. Then a lot of gas accumulates, which flares up during ignition. It is obligatory to carry out diagnostics of the unit: burner, igniter, electrode, contacts and connections.
Wick blockage
When ignited, the product slams, which indicates a clogged wick or chimney. The problem is typical for semi-automatic models. Inspect the wick: if a blockage is found, clean it.
To make sure that the chimney shaft is clogged, check for draft:
- Hold a lit match near a control window or vent.
- If the flame deviates to the side - the draft is normal, if it burns evenly - cleaning is needed.
For your part, you can clear the shaft. But for complete removal of contaminants, it is better to contact the utilities.
In models with automatic ignition, the electrode could become clogged. Strip the part and install 3-4 mm from the burner.
Clogged nozzles
When heated, noise is heard, ignition does not occur, or the flame breaks out jerkily. Shut off the gas supply and clean the holes with a thin wire.
Wrong installation
If the calculation is incorrect and the instrument case is hung, the sounds of metal impacts appear. When the lining is heated, the metal expands, and when it cools, it returns to its previous position, which leads to extraneous sounds.
The same thing happens with pipes that are walled up in walls. When the heating is turned on and hot water is started, the pipes expand slightly, which leads to knocking. When installing pipes into walls, it is required to leave a gap for thermal expansion.
Clogged heat exchanger plates
Then the boiler explodes when heated. And the plates can become clogged with dust, soot and soot. Remove the housing and clean the parts with a metal brush, a special vacuum cleaner.
The mesh, which is located at the bottom of the case, could become clogged with dust. In an open combustion chamber technique, this leads to a reduction in thrust. Don't forget to clean up.
Incorrect operation of the circulation pump
As a result of uneven operation, resonance occurs in the system, which leads to extraneous noise. Correct pump settings.
Close the gas valve before starting any work.
Place a gasket under the housing to reduce vibration. Regularly service the unit and clean parts from scale and dirt. This will allow a long and safe operation of the boiler.
Loud noise during operation of the gas boiler may be a sign of a malfunction in the heating system. Extraneous noise occurs due to the manifestation of some kind of malfunction, which definitely requires the attention of a qualified specialist. Such a malfunction should not be ignored for a long time, as it can aggravate the problem and lead to an emergency stop. Strong noise from the boiler is a problem that can easily develop into the purchase of a new one. It's incredibly expensive and should be avoided.

Whistling, knocking, annoying rumble Why is the gas boiler noisy, it is faulty Why is the gas boiler or column noisy
The consumer buys and installs high-quality gas equipment at home, and the problem will come as an unpleasant surprise to him when making noise gas boiler or column. Does this always mean a major overhaul of equipment? Can a home master eliminate the cause of the noise on his own? What to do, if making noiseboiler when hot water is turned on. The equipment still has a warranty period, everything is clear here. Noisy column "Neva" - you need to take the purchase to the store and exchange it for a new one. The warranty is over - there is only one way out. In this case, you will have to call the specialists of the bureau.
Reasons for the noise of a geyser or boiler
The boiler makes noise and does not let you sleep at night. Extraneous sounds when the equipment is turned on are signs of a malfunction in the heating system. Only a professional specialist can find out what happened. You should not listen for a long time to how the boiler makes noise, this is fraught with serious consequences. A consumer who ignores problems in the heating system may contribute to the fact that the problem is aggravated.
Reasons why the heating boiler is noisy:
- The fan has failed.
- Heat exchanger clogged up.
- Not enough water in the heating system.
- Low pressure in the heating system.
There are three common reasons why a speaker is noisy:
- Insufficient traction.
- Strong pressure in the system, gas escapes from the burner and beats against the wall in the place where the bend is located.
The consequences of what will happen if the malfunction is not eliminated when it makes noise, then an emergency stop of the heating equipment is possible as a result. In winter, this can lead to the repair of not only one unit, but the entire heating system. Noisy geyser - water heating equipment will not work properly.
What to do - ways to eliminate
The Beretta column is noisy, which means you need to contact the gas equipment repair service. If the boiler is buzzing, the user can independently check the water level in the system and top up if necessary. Noisy pump in the boiler - it may not be scary when the sound comes from the pipeline and radiators: air has entered the system and needs to be bled. If the pump itself is noisy, then a factory defect is possible. Periodic preventive cleaning of the heat exchanger from scale should be carried out. It is necessary to adjust the supply of blue fuel to the system: a very large pressure is undesirable.
It will be difficult for a person who has never repaired equipment to determine the cause of the breakdown, because he will have to do it by eye. And for professional diagnostics, you need to use special equipment and tools.
If the boiler makes noise when heating water, will determine exactly why this is happening, only a professional master. It is necessary to apply to the repair bureau.
Noisy after turning off the water in the water supply there is no water. At the same time, sounds can be heard from radiators and pipes too.
When turned on, the geyser makes noise, it is possible: you need to adjust the water supply. Water heating equipment has a special handle designed for this.
Hello dear readers. Why is the gas boiler noisy? This question is very relevant for the owners of this equipment.
Noises in a gas boiler may reflect difficulties in the heating network. It is necessary to quickly identify the causes and eliminate problems, otherwise the equipment may completely fail.

Why does the gas boiler make noise? Whistling, knocking, annoying roar Why is the gas boiler noisy, it is faulty Reasons why the heating boiler is noisy
A newly purchased gas boiler heats the room in the same way as silent as an electric kettle.
However, after some time (depending on how to install, adjust the boiler), he may rumble loudly or, conversely, hum like a car.
Why does the gas boiler click and why are these noises dangerous?
Knocks, clicks, vibration or sometimes even "explosion" in gas boilers occur most often due to build-up of dirt and fossils in heat exchangers hot water or in the main heat exchanger heating center.
The clicks or hums themselves do not pose a danger to the residents of the house. No defects or malfunctions due to them will appear.
The most they bring is discomfort.
Reference! However, clicks (and other noises) usually become fault indicator in a gas boiler. This can be either a serious breakdown of the part, or a build-up of dirt.
The gas boiler clicks during heating, turning on and / or turning off.
During power up
In this case, a large amount of gas accumulates. When a spark appears, the gas flares up and a pop is heard.
- This kind of noise is caused clogging of the wick (if the gas boiler is semi-automatic) or defective chimney. At the same time, the electrodes are also clogged (in boilers with automatic ignition), which close and click. During heating, they deviate more.
- Clogged nozzles in the burner lead to a poor-quality mixture of natural (or liquefied) gas and air. This is evidenced by the noise when the fire is ignited.
During the heating process
- The gas boiler makes noise in case of improper installation of the hinged brackets for the radiator mount. Then, during heating (sometimes during cooling), thermal expansion will not be balanced in the heating system.
- Clogging of the mesh in the body also leads to clicks. This reduces the thrust when heated.
- Sometimes there is a resonance in the system due to improper operation of the pump.
- The evaporation of a large amount of water is also accompanied by various sounds.
When cooling
A lot of free space is needed for heat to spread, and if the pipes were installed without taking this into account, then most likely the boiler will click or crack.
This phenomenon is most noticeable when cooling the heating devicewhen the temperature changes downward.
How to get rid of unpleasant sounds?
Good way - convert an open water supply system to a closed one. Then the water boils a little less, and the sounds will also be less. Also, this procedure will additionally protect metal parts from lime or corrosion.
Attention! Changing the type of systems does not affect its functioning without a pump. Changing the system is the installation of air vents and the replacement of the expansion tank with a membrane
With the accumulation of dirt, the situation is somewhat different. When lime forms on the walls of the gas boiler, the temperature inside these walls gradually increases. This, in turn, will lead to a reduction in the life of the heat exchanger and to the appearance of clicks and knocks.
Important! Not only clicks and taps are a sign of deposits in the boiler, but also such characteristic sounds as vibration, cod and "explosions" (in advanced cases). Only cleaning the gas boiler from lime will help here
This is done on its own.

Whistling, knocking, annoying roar Why is the gas boiler noisy, it is faulty Why is the gas boiler buzzing
In order for the heating system to work properly and for a long time, it needs to provide quality service. Malfunctions can occur for various reasons, the symptoms of problems can also vary.
One of the most common problems is the appearance of extraneous noise and whistles in the heating system. Ignoring the problem can lead to other troubles arising, which in the end can lead to the loss of efficiency of the heating equipment.
A whistle in a gas boiler may indicate one or a number of breakdowns. If they are not eliminated, an emergency situation will soon arise.If you are not sure that you can deal with breakdowns on your own, do not take risks, entrust the work to professionals. The first thing they must do is determine the reason why the gas boiler is whistling.
Very often, extraneous noise in the heating system appears as a result of oxygen entering the coolant. The problem situation most often occurs in open systems. The fact is that oxygen, which enters the coolant, is released in small bubbles when heated. The sound is similar to that produced when the kettle boils.
In this case, it is more likely not about malfunctions in the operation of heating equipment, but about discomfort for the residents of the house. If the whistle is the result of oxygenation of the water that circulates through the pipes, there is no danger to either the residents or the heating elements. But the noise must be eliminated, as it adversely affects the nervous system. Besides, the owner is probably worried about that.
The only way out of this situation is to equip a closed heating system, but this process is quite time-consuming and requires financial investment. How can I do that?
- install air vents on heating equipment;
- install a membrane tank instead of an expansion tank;
- provide automatic feeding of the heating system;
- set up a weather-sensitive automatic system.
These measures help to improve the performance of heating equipment, as well as make the operation of a gas boiler more comfortable.
Clogged heat exchanger
The water that enters the heating system is not previously cleaned or filtered, so when it is heated, a precipitate forms. Over time, it forms scale on working parts, which reduces the performance of devices, and extraneous noise appears.
The heat exchanger is one of the most important functional elements. It heats up as a result of gas combustion and transfers heat to the coolant. The whistle does not appear immediately, but only some time after the start of the operating period of the equipment. Lime deposits affect the life of the boiler, significantly reducing it.
There is only one way to solve the problem of why a single-circuit gas boiler whistles, if it is caused by the formation of lime deposits. It's cleaning the heating system. This can be done with the help of special chemicals that are sold in household chemical stores.
Fan failure
The fan performs a very important function. He is responsible for blowing the smoke removal system, contributes to the forced removal of combustion products from the boiler. If the fan does not work properly, periodic noises and whistles appear. In new boilers, problems of this origin occur infrequently, but if the service life is already quite long, it is quite possible that there will be malfunctions and malfunctions in the operation of functionally important parts. There are other factors that contribute to the rapid wear of the fan:
Noise source in the boiler
The noise in the boiler may have some differences:
- Uniform monotonous.
- Uneven, crackling.
In this case, the first type may occur even during the operation of a new boiler, but the second may appear after some time of operation. What can be the reasons for their occurrence?
Reason 1: Water saturation in the system
Let's try to figure out why the heating boiler is noisy?
As follows from practice, most often those installations that are connected to an open-type heating system make a sound. The reason may be the saturation of the water that circulates in the system with oxygen. It is released when water is heated and forms small bubbles, while the process is accompanied by a characteristic sound (you can recall, as an example, the process of boiling water in a kettle).
Why is this noise dangerous?
This process does not pose a danger to the boiler and the heating system. No defects or threats to work will also happen. But, it can create discomfort in living rooms.
How to get rid of it?
The only option would be to change the type of system from open to closed.
The process does not require time and investment, and an additional positive point will be the additional possibility of protecting the metal components of the structure from corrosion.
At the same time, changing the type of system will not affect the possibility of its functioning without a pump. The process of changing the type of system consists in installing air vents on the boiler and changing the expansion tank to a membrane one.
You can also install an automatic make-up system and a weather-sensitive automatic system, which will make the use of the unit more economical and comfortable.
Reason 2: lime deposits
Another thing is when an extraneous sound does not appear immediately, but after a certain period of time. Let's try to figure out why the boiler makes noise in this case?
The thing is that lime deposits lead to noise. They form on the walls of the heat exchanger after a certain period of operation.
Such deposits lead to the fact that the temperature of the internal walls of the heat exchanger begins to increase, which also affects the wear resistance and durability of the structure.
The characteristic sounds that a boiler with deposits has formed are not only noise, but also strong clicks and knocks (they appear with heavy deposits).
How to get rid of?
Only cleaning the heat exchanger from formations will help get rid of this type of noise.
Tip: craftsmen advise periodically washing the parts of the heat exchanger in a 4% vinegar solution. It is better to do this after removing the heat exchanger, and be sure to rinse the parts with clean water.
From the foregoing, we can conclude that there are actually not many reasons for the noise of a heating boiler, and they can be easily diagnosed and eliminated.
