The service life of heating radiators in the apartment. Bimetallic radiators: device, characteristics and nuances of choice. The main technical characteristics of aluminum radiators are as follows

When installing new heating systems or upgrading old ones, the right choice of radiators is of no small importance, the reliability of which can become a determining parameter for the durability of the entire system. Therefore, the service life of heating radiators is indicated by manufacturers in the accompanying documentation and on the packaging.

For various types appliances, provided right choice and installation, it is:

Factors that determine the life of heating radiators

When buying radiators, it must be taken into account that the actual period of their operation depends on the following parameters of the heating system:

operating pressure in the heating system;
test pressure;
chemical purity of the coolant;
coolant temperature.

Operating pressure is determined by the type of heating systems, and for private houses it is usually 3–5 atmospheres, and for multi-storey buildings 8–16 atmospheres. The operating pressure of the radiator, guaranteed by the manufacturer, must be at least 2 atmospheres higher than the operating pressure in the system.

The same variety with heat transfer fluids: antifreeze solutions can be used in cottages, and in district heating water usually undergoes chemical treatment.

Another danger to the operation of radiators lies during the seasonal start-up of heating systems, when water hammer occurs, and not all materials and structures are able to successfully withstand it.

Therefore, when choosing, it is necessary to take into account the susceptibility of the radiator material to negative influences. For example, cast iron is an inert, brittle metal, steel quickly corrodes at the welding points, and aluminum is destroyed by increased acidity of water.

Features of cast iron and steel radiators

These properties of metals explain the fact that classic cast iron radiators are immune to water quality, but very sensitive to water hammer and pressure in the system exceeding 9 atmospheres.

Steel radiators quickly fail in the presence of oxygen in the water and when the operating pressure in the system exceeds the standard for these batteries (8–10 atmospheres). Therefore, they work reliably only in autonomous systems heating.

Acidity and general contamination of the coolant have a critical impact on the service life aluminum radiators. This type heating appliances appeared relatively recently, but has already gained popularity primarily because of its consumer properties, which are due to the physical and technological characteristics of aluminum:

ease;
high thermal conductivity,
high fluidity,
plasticity.

Therefore, they have a high rate of heat transfer and are very productive. They are light, reliable and successfully resist water hammer.

However, aluminum radiators, just like steel ones, are sensitive to high pressure and draining the coolant from the system, since in this case corrosion processes are faster. That's why modern designs provide for the presence of shut-off valves and an automatic gas outlet valve. Manufacturers recommend installing such radiators in private housing construction with controlled water acidity, which will eliminate all risk factors for these aesthetic products.

All the advantages of aluminum radiators, but without their shortcomings, are embodied by the developers in bimetallic radiators. The strength and durability of these products is ensured by the use of steel collector pipes for contact with the coolant, which significantly reduces the destructive effect of water. The optimal combination of the strength of steel and the thermal conductivity of aluminum makes it possible to guarantee a service life of 25 years at the highest working pressure for such devices (up to 24 atmospheres), that is, optimal choice for multi-storey buildings.

This design guarantees their durability under the influence of all adverse factors of domestic centralized heating networks, namely: low level of water treatment, unstable pressure in the systems, seasonal discharge of the coolant.

The maximum service life of heating batteries is ensured not only high quality their manufacture, but also taking into account when choosing all the features (working pressure, water treatment, etc.) of heating systems in private or multi-storey buildings.

That is, if there are valves at the radiator, it belongs to the owner of the apartment, in the absence of such, it is common house property and either the management company or the authorized persons of the partnership are obliged to monitor its condition. Thus, we can state: any heating radiator, separated from the common house riser by some kind of valve, becomes the property of the owner of the apartment and the responsibility for its condition / timely repair lies with the owner. In other cases, the battery will be common property and, accordingly, it should be monitored by authorized MKD management organizations.

Replacing heating batteries in an apartment: with your own hands or through a housing office

An example of a claim management company about replacing radiators. to the contents If the batteries leak after the heating is turned off If the heating radiators leak after the heat supply to the MKD is stopped, the malfunction should still be eliminated, but not in such a hard mode. A battery leak indicates that water has not been drained from the system. The procedure is as follows:

Residents report a problem to the Criminal Code.
Employees of the UK repair the leak, if possible, or change the battery at the expense of funds handed over by the owners.

Only a specialist servicing the MKD will quickly be able to block the riser or cut off the entire staircase from heating.

You can learn how to achieve the replacement of the heating riser from the housing and communal services from the video: to the content Who is responsible for emergency? In an emergency, all responsibility lies with the technical service of the Criminal Code, HOA or Housing Office.

Who Should Change Batteries: Responsibility of the Parties, Heating Repair

As a result, the homeowner buys and replaces the battery on his own, providing heat in the house. ATTENTION! In the event that the owner of the apartment repairs the heating system on his own, he may demand compensation in the amount of the cost of the radiator. Unfortunately, it is difficult to achieve this compensation even through the court, the management company finds arguments in its defense.
Therefore, it is better to first consult with an experienced lawyer when it is possible to present an invoice to the Criminal Code before starting a controversial case. The main features of the process During operation, the batteries wear out, for better job heating system needs to be replaced. But radiators, as common house property, at whose expense to change the premises of the apartment.
The management company may not consider such work necessary, but according to the law, the possibility self repair common property is limited.

Service life and repair of heating batteries in the apartment: causes of failure

She must monitor the condition of the risers of an apartment building, heating pipes, conduct repair work if necessary. Battery replacement is free of charge. If there are shut-off valves in front of the apartment, the owner of the home usually pays for the replacement of radiators. If the risers of the management company repair unconditionally, then the management company often refuses to change the equipment in the apartment for free.

ATTENTION! In this case, you should write an application for a replacement officially, register it. It is recommended to consult on this issue with a lawyer experienced in the field of communal law. If the management company ignores consumers and does not deal with its direct business, a written appeal will become the basis for going to court.

Who should change the leaking battery in the apartment and at whose expense?

But in paragraph 5 it is clarified that only everything that is up to the valve located on the outlet from the riser towards the apartment will be considered common. Thus, if apartment radiators can be disconnected from the entire system, then they cannot be considered common house good. In the absence of such a valve, intra-apartment batteries are part of the common house heating system.

back to contents At whose expense is it carried out? There is an unequivocal answer to the question of who should pay for the replacement of radiators in an apartment, and this answer is as follows: the owner should pay. to contents In privatized If housing is privatized, then when replacing normally working heating appliances with more modern version the owner must pay, as well as when the batteries do not belong to the general house good.

Who should change the batteries in the apartment if it is privatized

In the issue of heating radiators, there are disputes about exactly who they belong to and who, accordingly, is obliged to monitor their condition. See also: How to attach a balcony to a room and insulate it: the order of the procedure and its features Supreme Court RF. In accordance with the provisions of these regulatory legal acts, heating radiators can be treated as common property of residents of MKD only if they are not separated in a particular apartment from the common heating system by any valve or similar separating unit.

Topic: why don't they change batteries in a non-privatized apartment at the expense of housing and communal services ???

When the topic of the urgent need to replace existing radiators with new ones is strongly discussed, then someone is interested in selling radiators or in providing paid services that make up a round sum on the scale of MKD. The decision on the total change of heating devices is entitled to be taken by the Criminal Code at the general meeting of the owners of the premises. Before bringing such a question to the court of the owners, it is necessary to carry out a number of calculations with an economic justification in favor of one or another option.
Replacing batteries is an issue that can be resolved without intervention. officials UC is impossible. Even if apartment radiators can be disconnected from the riser and considered the property of the owner of the apartment, these devices are still involved in common system heat supply.

Battery in the apartment: whose property and who should repair it?

If you want to change outdated equipment to new one, you should contact the management company or another authority that is responsible for heating systems in apartments.

If the replacement is carried out with similar designs, it is enough to simply provide information about the upcoming installation work.
Radiators of another model will be installed, which may lead to an increase in the heating area? Representatives of the management company will perform an examination to find out the possibility of changes in thermal balance building. The master will inspect the area of \u200b\u200bthe house, new batteries, and study their technical data.
Also, the examination is carried out in the case when the overhaul of the apartment involves a change in the configuration of the pipeline.

IMPORTANT! It is necessary to carry out work taking into account all the requirements of communal legislation. In this case, they will not be considered a violation.

In this scenario, it turns out most often that there were no scheduled inspections of the general house economy, there was no system test, as a result of which they looked at a leaky pipe, a radiator. How to calculate ODN for electricity according to the established standard? Read about it here. back to contents Replacement procedure overhaul MKD, but is an initiative of residents, then the purchase of materials and work will be carried out at the expense of the users of the apartment themselves. It is important to realize that unauthorized actions with heating system are not allowed.

Normal operation of heating radiators for an apartment in high-rise building depends on a number of important factors, where the duration of use, determined by each specific manufacturer, plays an important role. Based on the material of production, various batteries can last from 15 to 35 years.

In view of the fact that it is an investment in the long term, choosing devices for equipping apartment system heat supply, you should ask how long devices of a certain type last and what can affect their durability!

Service life of heating radiators in residential buildings

The average indicator of the period of stable operation according to GOST, depending on the material of execution, is as follows:

Steel - 15-20 years;
Cast iron - 25-35 years;
Aluminum - 20-25 years;
Bimetallic - 25-30 years.

However, these characteristics are contrary to the actual data. The stability of the system depends on its real technical parameters and terms of use. Operation of heating radiators in residential buildings depends on:

working pressure of the coolant;
the chemical composition of the substance;
average temperature water in the system;
the likelihood of water hammer.

Service life of aluminum radiators

The degree of resistance to negative influences that can affect the durability of the battery is determined by the metal from which the device is made. Thus, the operation of aluminum heating radiators is designed for a period of 20-25 years with a warranty period of 5 years from the date of actual installation and inclusion in the system.

At the same time, it should be noted that such a long period work is provided only with proper care and compliance ideal conditions use. There are a number of factors that can reduce the life of this type of battery to zero:

High working pressure;
Low resistance to water hammer;
Susceptibility to corrosion due to high level coolant pH.

Service life of cast iron radiators

Despite the declared term of service up to 35 years, subject to all rules, operation cast iron batteries heating can reach more than 50 years. This phenomenon can be explained by the high resistance of cast iron to corrosion processes. For apartments in Moscow, a similar option is ideal solution, having a set of advantages and advantages in comparison with equipment made from other types of metals.

One of the main factors that are taken into account when choosing heating batteries is the durability of the use of appliances. It defines the period during which it is possible to provide comfortable conditions in residential and office space without spending Money to replace equipment. The service life of the radiator depends on the materials used and the manufacturing technology. It is indicated by the manufacturers of heaters on the packaging, in the passport and in other accompanying papers.

What affects the duration of operation

Technical characteristics of batteries and test methods before sending products to consumers are regulated by the provisions of SP 60.13330.2012, GOST 31311-2005 and others normative documents. They also reflect the features of the marking, completeness and content of the instructions for installation and use of heating appliances. How long do batteries made of different materials in accordance with the requirements of GOST, and some specifications indicated in the table.

The average life of radiators of different types

In addition to the quality of the raw materials used and compliance with the regulations technological process Other factors also affect the life of the radiators. Among them are:

correct installation;
regularity of maintenance;
the value of the working pressure;
maximum allowable temperature in heating networks;
composition and quality of the coolant transported through the pipes.

The operating pressure depends on the characteristics of the heating. In autonomous networks that are used to maintain comfortable temperature in the premises of private houses, it varies from 3 to 5 atm. The pressure in the central heating systems of multi-storey buildings is about 8-16 atm. To ensure the duration of the use of radiators, their working pressure must exceed the same parameter in the network by at least 2 atm. The composition of the coolant also differs. In autonomous networks, antifreeze solutions can be used, and water for central communications is usually subjected to chemical treatment.

In addition, the duration of use of batteries installed in apartments with central heating, hydraulic shocks in the pipeline have a negative effect. They are due to pressure drops and often occur during start-up. engineering communications at the beginning heating season. Since for the production of radiators they use different materials, then their level of resistance to external influence, reliability and durability differ significantly. Some manufacturers achieve improvements in technical parameters and increase in service life by introducing new technologies and methods for processing metals.

Characteristics of steel radiators

The least durable heating devices include steel batteries, the service life of which is from 15 to 20 years. They are characterized by a low resistance to corrosion, leading to deformation and destruction of products. Heating appliances made of poor quality metal are especially prone to rust.

Forged radiators steel sheets withstand pressure, the value of which is not more than 8.5 atm. Exceeding this parameter contributes to the destruction of welded joints and failure of products. Damage can also occur as a result of water hammer, so it is recommended to install steel batteries in autonomous networks that serve to heat private houses.

Features of aluminum batteries

Aluminum radiators are also used in heating systems that are not connected to central communications. Operation of such batteries in conditions apartment buildings may damage the metal. They are characterized by the following:

good heat dissipation;
light weight;
the ability to choose a heating device with the right amount sections;
variety of shapes and sizes;
distribution of heat by convection flow, which is created due to the shape of the fins.

However, aluminum radiators are not able to withstand high pressure: their maximum is 8 atmospheres in the current mode and 16 - during pressure testing. They are slightly resistant to hydraulic shocks and are sensitive to the composition of the coolant. At elevated level acidity of the working environment, there is a high probability of corrosion. It can also occur in the absence of water in the system, so it is undesirable to drain it.

When controlling the pH level of the coolant and maintaining the pressure within the specified limits, aluminum batteries will last about 20 years. Installation of products in central networks is undesirable, since they will soon need to be replaced, which will lead to additional costs.

Durability of cast iron radiators

The most durable heating devices are cast iron, which usually perform their functions for 25-35 years. The service life of some products can reach up to 50 years. This duration of operation is due to the following characteristics:

resistance to corrosion;
low sensitivity to the quality of the coolant;
the ability to maintain their parameters at temperatures up to 130 °C.

Due to material properties, cooling cast iron radiators slower than comparable products made of aluminum or steel. However, they are not designed for pressures above 9 atmospheres and therefore cannot be used in the installation of central communications. In addition, cast iron is a brittle metal and is subject to destruction under the influence of hydraulic shocks. Cast iron heating devices can last as long as possible if protection against sudden pressure drops is provided, and its value in normal mode does not exceed the permissible values.

Service life of bimetallic batteries

Bimetallic models are less durable than cast-iron counterparts: their service life averages from 25 to 30 years, and manufacturers usually provide warranties for 10 years. This service life is achieved due to the following factors:

good strength indicators, which are obtained due to the design features, providing for the presence of a steel core;
ability to withstand at least 20 atmospheres;
high level of resistance to hydraulic shocks.

Bimetal radiators are distinguished by good heat dissipation, aesthetic appeal and low weight. The availability of products with different axial distances provides wide opportunities when installing. They are resistant to corrosion and are not sensitive to the composition of the coolant.

Bimetallic heating devices are able to maintain their functions for a long time both in autonomous networks and in centralized systems of high-rise buildings. However, it is more rational to use products when laying communications in multi-apartment buildings, where they show maximum efficiency throughout the entire service life.

Benefits of Lammin products

Lammin sells bimetal and aluminum radiators of the Eco and Premium series own production. The warranty period for the first products is 7 years, and for the second - 10. They meet the requirements European standards and adapted for use in Russian conditions. The high quality of heating devices is achieved through the use of modern production lines and the introduction of special developments.

Bimetallic batteries are ideal for heating offices, apartments in high-rise buildings and industrial premises. They are insensitive to the composition of the coolant, since the design does not allow contact between aluminum and the medium transported through the pipes. Aluminum models are obtained by injection molding from a unique alloy and are used in the installation of autonomous heating networks in private homes and country cottages. They differ increased strength and reliability. Protective covering inner surface protects metal from corrosion.
