Heating batteries are noisy, what should I do?

Heat in our apartment depends on the heating system. If the installation was carried out by professional builders, then there will be no problems in the winter. However, often with independent installation work, miscalculations are allowed, which are the cause of various unpleasant moments and discomfort. The appearance of noise in the batteries is a little nuisance for someone, but for someone a real disaster is getting on my nerves. Many homeowners wonder why there is knocking and noise in the heating system and what to do about it.

What is the cause of noise in batteries?

There are many reasons for the hum in the heating system and radiators. But most often the radiator makes noise as a result of violations of operating conditions.

Adjustable head

The large pressure of the coolant when it enters the radiator creates a noise similar to the hum of a crane under strong pressure. This noise, which depends on the flow rate of water into the battery, is easy to handle. It is only necessary to install a flow control apparatus at the radiator inlet, which will reduce it to normal values.

Gurgling sound

Another common variation is the irritating hum inside the radiator. This is the formation of air chambers in batteries. This problem can be easily eliminated by lowering the air plug through a Mayevsky crane or other installed cranes.

Resonance in the circulation pump

The circulation pump supplied in the heating system is of great importance. But, when its nominal properties are selected incorrectly, it may be due to noise in the battery. The appearance of resonance with an active circulation pump can be eliminated by adjusting the efficiency, pressure and speed of revolutions in the pump according to the system features. Sometimes, to eliminate this phenomenon, it is enough to install anti-vibration couplings at the junction of the pump and pipes.

Violations of the rules of fastening and installation

The problem is in the brackets

In some cases, the basis for noise in the heating system may be support brackets, which did not coincide with the support points of this type of radiator. Noises resembling the sounds of shock, which are clearly audible at the time of heating and cooling the battery. It is easy to eliminate such noises, it is worth trying to install a rubber gasket on the bracket.

Walled up by the rules

Noise can result in pipes placed in “gates” and concreted without proper insulation. Since the pipes at thermal expansion should have some freedom, then close to the wall to lay them is not recommended. Appearing noise is transmitted to the battery even with small fluctuations in the temperature of the coolant. To prevent such noises, it is necessary to place the pipes in a special insulating material - merelon before laying. This procedure eliminates the hum, condensation and disturbance of the surface of walls and floors.

It's all about the thermal valve

If the batteries are noisy, you can check the thermal valve. In some cases, with self-assembly, this device is placed on the wrong side. Locking devices under the influence of the coolant supplied under pressure, begins to knock.

Blame the boiler

If the boiler is selected incorrectly, accordingly, the entire heating system in the apartment will not work correctly. The interval between shutdowns of the boiler, depending on the system, should be from 20 to 40 minutes. With frequent changes of the on and off mode, it can be assumed that the flow is incorrectly adjusted, so the radiator is noisy. The boiler capacity should be within 70 ─ 80% of its declared capacity. What to do in this case? This problem can be easily solved if you install a room thermostat on the radiators.

Leaks

Sometimes, for some reason, a thin whistle is heard from the battery. Most likely, a pipe has been broken somewhere. In this case, you need to quickly find a broken pipe.

Sometimes, with flushing the heating system plumbers forget to close the valve, and the coolant enters the sewer system, and, therefore, the radiator is very noisy.

Garbage appeared

Small pieces of slag trapped in the radiator and tapping the walls can be removed with a simple rinse. To do this, connect the hose to the tap and open it, and drain the water with pieces of slag.

Briefly about the main thing

Here are the main reasons when heating radiators are noisy and there are knocking and clicks in them. The main thing is to correctly establish the cause. It is best to start on your own to take simple steps: bleed air, check the locking mechanism and eyeliner, install rubber gaskets.

All possible problems are fixed, but still the batteries are noisy? If you can’t independently establish the reason why the radiator is noisy, then call a heating technician-professional.
