Heating boiler is buzzing when turning on

Several reasons why the gas boiler clicks and makes noise. How to eliminate malfunctions

If water is noisy during the operation of heat supply in the heating pipes, then there are certain causes of this effect. First you need to identify them, and then proceed to reduce noise or its complete elimination.

Why is the water noise in heating pipes and how to correct this drawback correctly? We will deal with the main types of extraneous sounds. It is they who indicate the objective factors of the occurrence of the not desired effect:

• Crack in pipes. Occurs when the heating system is turned on;
• Clicks appearing with a certain frequency;
• Constant hum in transport highways;
• Barely audible knock.

All these extraneous effects. the noise in the heating battery or radiators significantly reduce the comfort of living in the house. In addition, they may indicate incorrect heat supply work. If you do not take actions to correct the situation in time, any heating element may fail.

If the heating pump or other component of the system is noisy, you should first try to localize the cause of extraneous sounds. For this, it is recommended to use the following technique:

• Track the frequency of the effect.
• Try to identify dependence. an increase in temperature in pipes, pressure surges, etc.D.
• Make sure that the noise in the heating boiler comes from it, and not from other objects located in the boiler room.

If it was revealed that the source is a component of the heating system. certain actions should be taken to eliminate this phenomenon.

Why is the heating pump heating

When installing a closed.type heating system, a circulation pump is installed on the pipeline. The main task of this device is the pumping of the coolant, water or antifreeze, which ensures the quick and uniform heating of all residential premises of the cottage, cottage or any other country house. Thanks to the pump and automation of the boiler, the user can set optimal temperature indicators in his home, but sometimes such a device overheats and cannot efficiently perform the tasks assigned. In our article we will get acquainted with the reasons for this phenomenon and methods of solving such a problem.

need to eliminate problems. By the way, it is recommended to protect the pump from drops on the network by installing a reliable stabilizer. Such a move will also protect the pump from combustion of a fuse, which fails as a result of constant pressure drops in the network

So, if, nevertheless, the trouble happened with your circulation pump, and he refuses to work, then we will try to repair the unit with your own hands.

Important: But if you are not sure of your abilities or do not have the appropriate tool at hand, then it is better to contact a specialized center

If the pump emits a rumble, but the working wheel does not rotate

The reasons may be the following points:

• The presence of an outsider in the working wheel zone;
• The rotor shaft was oxidized due to long.term downtime of the unit;
• Violation of power supply to the terminals of the mechanism.

In the first case, you need to carefully remove the pump from the heating system and spin the case in the working wheel. If a foreign object is detected, eliminate it and turn the shaft with your hands. When assembling the pump in the reverse order, it is necessary to install a reliable filter on the pipe.

If de has a place to be oxidized, then it is well cleaned, all movable elements of the working unit are lubricated and the pump is assembled in the reverse order.

If the problem is the supply of power supply, then you have to check the voltage using a tester. First, in all sections of the cable and when a gust or malfunction is detected, completely replace the last. Then, if the cable is in order, check the voltage on the terminals. If the tester shows infinity, there was a short. If it shows less voltage, then there was a break in the winding. In both cases, the terminal is replaced.

If the unit does not show signs of life at all

This can happen if there is no voltage on the network. With the help of the tester, check the voltage and, if necessary, eliminate the problem.

By the way, it is recommended to protect the pump from drops on the network by installing a reliable stabilizer. Such a move will also protect the pump from combustion of a fuse, which fails as a result of constant pressure drops in the network.

If the pump turns on, but then stops

In the first case, you will have to disassemble the pump and check it for the presence of scale. In case of detection, the lime plaque is removed and all the joints between the rotor and the stator are lubricated.

If there is no scale, then check the fuse density on the unit. Remove it and clean all the clamps well. Here it is worth checking the correct connection of all wires in the terminal box through phases.

If the pump gives a heavy noise when turning on

The reason for this is the presence of air in a closed circuit. It is necessary to release all the air masses from the pipes, and mount a special unit in the upper part of the pipeline to prevent the formation of air traffic jams.

Another reason may be the wear of the workplace bearing. In this case, you need to disassemble the aggregate case, check the bearing and, if necessary, replace it.

If the pump is noisy and vibrates

Most likely, the matter is insufficiently pressure in the system. It is necessary to add water to the pipes or increase the pressure in the input pipe of the pump.

If the pressure is small

Here it is worth checking the direction of rotation of the working unit in the pump body. If the wheel spins incorrectly, then, probably, an error was made when connecting the device to the terminals through phases in the case of using a three.phase network.

Another reason for a decrease in pressure can be too high the viscosity of the coolant. Here the work wheel is very resistant and does not cope with the tasks. I have to check the condition of the mesh filter and, if necessary, clean it. It will also be useful to check the cross.section of the input and output pipes and, if necessary, set the correct parameters of the pump.

The causes of noise

Due to the very principle of operation of the equipment, you can hear a little noise, it cracks. Sounds may intensify if the room is not ventilated enough. There is nothing wrong here.

The device makes sounds when hot water is turned on or heated? When watering water, you can feel vibration, because the flow passes through the pipes, turns, passes through obstacles. To reduce the noise level, you can adjust the water supply handle. Scrolling it, listen: as soon as sound vibrations decrease, leave in this position.

Cotton is heard when starting

You start the equipment and hear cotton? The device twitches and vibrates? So there were problems with gas supply. When starting in the working part, fuel accumulates: when the amount of air or gas corresponds to the norm, the cotton should not be heard.

An excess gas leads to a voluminous explosion when the fuel hit the wall at the place of bending hard. This can happen at excess pressure in the system.

Such problems can even lead to a breakdown of the chimney. So contact the service center or try to eliminate them yourself.

• Disconnect gas and water.
• Remove the equipment casing: pull the handle on yourself, unscrew two screws.
• Inspect the fuel supply system and burner. Clean the details of dirt. How to clean a gas column. Read in the previous article.
• Unscrew two screws of the tongue of the burner.
• Inspect the condition of the nozzle. If it is clogged, do cleaning.

The column buzzed and rustled

The main reason is a poor craving. To check it, light a match and bring it to the hole. If the flame deviates to the side, as from the air flow, the thrust is in order. If not, the chimney canal was clogged with soot and a toast that are produced in the process of combustion. Need to clean it.

Poor ventilation also helps to increase noise. This often happens after installing plastic windows. Packages are so sealed that natural ventilation becomes impossible.

What to do if the device is cracking? Similar is possible with a block of nozzle (nozzles) burner. You need to disassemble, as described above, and clean them.

If your column is turned on by an electric carbon, the reasons may be as follows:

• Similar devices work on batteries. Когда они разряжаются, топливо плохо поджигается либо не загорается совсем. Clicks may be heard. In this case, replace the batteries.
• The flow control sensor is faulty. Most often, its contacts are oxidized under the influence of moisture. You can try to clean the contacts, but it is better to perform the replacement of the sensor.
• The spark does not light up. The candle that is responsible for the fire has shifted, so the process does not end. Install the candle in place, resume the process.
• The ignition deceiver does not work. Remove the part and shake. In this case, the noise of the ball rolling in the case should be heard. If nothing is heard, the ball is stuck or shifted. Return it to the place with wire.

New equipment is rattling? Perhaps the reason is not in the boiler, but in the error when installing. To find out, inspect all the connections, the correct connection. It can also be:

• Briefing of the duct. Air enters not only through the main hole, but also through the hole. Therefore, the noise intensifies.
• Incorrect placement of the burner. Perhaps she shifted and does not cope with the burning of the entire volume of gas. You need to install it in place.

The gas boiler whistles

If the product whistles and squeaks, you need to find out where the sound comes from. What to do:

• Cross the gas supply.
• Open the mixer in the “hot” position.
• In this case, the whistle intensified? So, the malfunctions lie in the water tract. The main reason is the deposition of the scale on the parts of the heat exchanger or on the pipes, the blockage. It is necessary to clean all the elements in order to resume the performance of the equipment and eliminate the cause of the whistle. The reverse butt of water can be cleaned from blockage.
• If the whistling sound disappeared when the tap is opened, the case is in the gas tract. Probably a valve defect has occurred, which controls the power of flame. Whistle can appear when increasing the power of work. Try to twist the regulator until the sound disappears. Does not help? Then the matter is the blockage of the tract. You need to disassemble and clean the device.

If you notice such problems in your technique, you can try to cope with problems yourself. But it is better to contact the service center, especially with the actual warranty coupon. Employees will carry out repairs or remove faulty equipment.

The reasons for the noise in the gas boiler and how to get rid of them

The most common reasons why the gas boiler is buzzing strongly are:

• problems in the fan;
• a large amount of oxygen in the coolant;
• sedimentary deposits on the details;
• reduction in gas pressure.

Problems in the fan

Sometimes the reason why the double.circuit gas boiler is buzzing is failures in the fan. This is drawn by a lack of lubrication, pollution of the blades. In this case, it is necessary to clean the fan and grease the bearing with oil. If necessary, a broken part is replaced with a new.

Excess oxygen in water

The buzz of a gas boiler can be monotonous or periodic with crackling. Even noise occurs even in new units. In this case, boilers are usually noisy, in which the coolant circulation is carried out naturally. The reason is an excessive amount of air in the coolant. The fact is that when heated in water, many air bubbles are formed that make noise. This is the answer to the frequent question of consumers, why the gas boiler is buzzing when heated. Such noise does not mean the presence of malfunctions in the gas unit, but causes certain discomfort.

The problem can be solved by re.equipment of the system into a closed. You can change the type of system by installing valves and replacing the expansion tank with a membrane. It will also be useful to connect weather dependent automation. Such measures will help extend the service life of the unit.

Sediment on the elements of a gas boiler

Another frequent reason why the gas boiler is buzzing strongly is the accumulation of lime sediment. When the coolant is heated, more than 60ºC begins to actively produce a scale, which over time clogs the pipes of the heat exchanger. In this case, the heat transfer between the contour and the coolant deteriorates, and the efficiency of the unit is significantly reduced. Under the influence of circulating water, the pieces of scraps are abandoned, and amenable to movement, while they fight against the metal walls of the heat exchanger and create a tapping noise.

The problem is solved by cleaning the heat exchanger. However, flushing can only be done by ordinary contours. If a bitter heat exchanger is clogged, then it will only have to be thrown away and acquired by a new. In addition, such contours clog faster than classic separate analogues.

note! So that the scale does not form in the heat exchanger, the filter should be installed on the supply pipe of the water supply.

After installing a peeled heat exchanger in a gas boiler, it will stop making noise.

Low gas pressure

In some cases, the noise in a gas boiler causes a decrease in gas pressure. Because of this, water circulation in the system is reduced, and air traffic jams appear. As a result, the unit overheats, trying to gain the required temperature, and begins to buzz.

You can eliminate noise by solving the problem of low gas pressure. The reason for the decrease may be:

• low pressure in the highway;
• gas pipeline pollution;
• the presence of leakage (accompanied by a characteristic smell of gas);
• A malfunction of a gas meter.

If the “root of the problem” in a leak or low pressure in the centralized line, then only representatives of the gas service can help here.

If the gas pipeline is clogged, then it needs to be cleaned. If breakdowns occur in the gas meter, the fuel will pass through it with difficulty. The symptom of malfunctions in the counter is noise and cracking emanating from it. After replacing the measuring device with a new pressure will return to normal, and the noise will stop.

note! You need to know the optimal indications of the gas pressure and periodically measure it. Value should be within 1.5-2 atmosphere.

Why knocking a heating boiler when heated. a circulation pump malfunction

This unit provides the movement of the coolant, increasing the efficiency of the system. In this case, there may be several reasons:

Unstable voltage in the network. The equipment works with interruptions, and the malfunction is most often inconsistent, sometimes manifests itself often, but it can occur occasionally. The problem can be solved by installing a stabilizer that supports stable indicators.

The presence of air plugs in the heating circuit. If the radiators do not break at the beginning of the heating season, when heated, incomprehensible sounds occur due to a large amount of air in the pipes, since the load on the impeller is uneven.

Wear of individual components of the circulation pump. Factory marriage or long operation provoke production. The shaft begins to vibrate, the impeller can be deformed or even partially collapsed, which will lead to loud knocking when working equipment. Most often, during breakdowns, the pump is changed, since most models are not.free.

Less commonly, extraneous sounds can occur due to errors when installing a private house heating. The absence of an expansion tank provokes an increase in cavitation loads and the system will make noise during operation, especially during heating. After installing it, the noise will disappear

Cases on models of certain brands

The following are the frequent causes of different noise in the boilers of famous brands.

First. Navien. If the error does not reflect on the display of the device, but the technique is buzzing and noisy, then immediately you need to quickly figure out why the Navyen gas boiler is noisy?

• The device is disassembled.
• The heat exchanger is cleaned or replaced.
• Cranes for maximum openness are checked.
• The temperature of the water is reduced.

The second. Bereta. Usually in their devices there is an atmospheric burner. Then the noises are very low. But if they increase, then in the units of the beret the reasons for this are most often:

• Weak thermal gear in the heat exchanger. At the same time, the use of DIA is completed. In the heat exchanger, scale accumulates.
• The pipes are incorrectly selected.

Third. Conord. These models are most often noisy with increased loads, for example in the cold. According to the documents, they are one power limit, in practice. the smaller. If the documentation indicates 13 MBAR, then in fact. 10 MBAR. Therefore, you do not need to configure the device to the maximum.

Fourth. Baxi. Most often, they are very noisy with heating function, with DHW. a weak noise. Actions: Baypas check, cleaning and valve tuning. This work is usually carried out by employees of the service.

Fifth. AOGV. Their users often complain about the whistle. After inciting it becomes stronger. After disconnecting, it disappears. For example, if the AOGV-17.4 model whistles, the reasons for this:

The sixth. Weland. Often these boilers are buzzing after ignition and turning off the fire (the pump is turned on). No noise heating. Causes:

Seventh. Ariston. The causes of noise in the boilers of this company lie in poor circulation of the thermal carrier.

It is necessary to extract and qualitatively clean the heat exchanger, blow it up with a compressor.

Eighth. Arderia. When the arderia gas boiler is noisy, usually the reason lies in the erroneous setting of the pump. If you can’t configure the pump, it changes under warranty.

The technique works noisily when heating water

Modern boilers work quietly, so vibration, noise, extraneous sounds should alert you. What can serve as an indirect reason:

There are also quite specific reasons why the boiler is buzzing.

Big oxygen

The water in the pipes is oversaturated with oxygen, which is why the bubbles are released when heated. This effect leads to increased noise and vibration not only of the apparatus, but also the batteries.

Air accumulation in the system

If the boiler knocks and puffs, it is necessary to lower the air in the pipes. Cranes are installed on modern radiators. By unscrewing them, you can remove accumulated air.

Big salts in water leads to their deposition on the walls of the heat exchanger. Therefore, when heated, the unit will hiss. In addition, the rate of heating and heat transfer is reduced. Once a year, it is recommended to clean the radiator. To do this, a pump with a reagent is prepared, treatment fluid is pumped through the hoses.

Fan problems

The fan works in models with a closed camera and forced removal of combustion products. Why does he make strange sounds during rotation, whistles:

• The lubricant in bearings was dried due to placement over the burner. Under the influence of high temperatures, the lubricant dries quickly, which leads to wear of the bearing. Dismantling and lubrication of part is performed.

Excessive pressure in the heating pump

The pump is pumped high pressure, you need to adjust its settings. Too high pressure in the system can lead to an emergency situation. You can adjust the values ​​by switching a white lever on a terminal box.

A lack of water in the system brings serious overheating. First of all, check the values ​​of the thermostat, set less indicators. Measure pressure, share the coolant if necessary.

• If the boiler is howls, the point is the incorrect tuning of the gas valve or bypass (pipe-crossbreaks).
• When working at high power, a gas meter can rattle.
• Worn valve makes rattling sounds.

Operation of non.freezing media.

One of the reasons for the appearance of extraneous sound in a thermal gas boiler is the use of the apparatus on non.freezing coolants. Their heat capacity differs from the heat capacity of the water, therefore, in some local parts of the burner, overheating occurs. If the reason really lies in a kind of conflict of materials, then the boiler makes a buzzing resembling a boiling kettle. It is best to simply adjust the power of the boiler, its maximum allowable heating temperature.

A characteristic noise similar to a buzz is most often caused by air traffic jams. They are formed due to the fact that the pressure has decreased. As a result, the productivity and coefficient of the useful system of the system along with the water level is reduced. In order to get rid of annoying sound, it is enough to easily correct the pressure level in the gas boiler in accordance with the permissible normal indicators specified in the technical passport of the device.

Question answer

Which boiler to choose so that it does not buzz?

I work with an atmospheric burner much quieter, since they do not have a fan. If you need a turbocharged unit, select models with a reduced noise level.

They put aluminum radiators and the boiler began to make noise whether it was normal?

Aluminum from the inside reacts with water, decomposing it into hydrogen and oxygen, due to which an oxide film forms on the internal surfaces. Until it covers all the cavities, there will be increased air in the coolant, then everything will normal

Is it possible to repair a fan?

First you should carefully open it and put a heat.resistant grease, it often helps. If it turns out to find the bearing of the right size, you can repress it.

How to reduce the risk of a rumble in a boiler?

It is necessary to maintain maintenance regularly. Wash the heating system and all elements at least once every 3 years. Pump air into the expansion tank.
