Overhaul of the heating system of an apartment building

Overhaul of the heating system in the apartment building

September 18, 2020

Major repairs are a set of measures aimed at eliminating breakdowns of worn-out structural elements of the heating supply of apartment buildings, which are part of the common property. At the same time, work is being carried out to replace or restore them in order to bring them to current operational standards (Article 2 of Federal Law No. 185-FZ).

Prerequisites for carrying out a major overhaul of the heating system:

development of the service life established by the standards (service life of steel heat supply communications - 25 years);
a situation arises when individual space heating elements that are in common ownership violate the established maximum permissible reliability characteristics and create a safety hazard (clause 21 of RF PP No. 491).

The need for a major overhaul of the heating system is determined by the service life of the pipes and equipment. These deadlines are set by the manufacturer. In addition, the operating conditions and the objective technical condition of the system are taken into account. Often the problems are obvious - the temperature regime changes, leaks and rust appear, which are accompanied by complaints from residents. In such cases, the heating system is examined and, based on the results, a defective list is drawn up for the planned major repair with an approximate list of work and necessary materials.

It should be understood that a major overhaul involves some large-scale actions, and not eliminating a problem in a single apartment.

The list of works during major repairs is individual for each type of utility network. It also depends on their technical condition and configuration features.

Work on major repairs of the heating system of the microdistrict

During a major overhaul, the entire heating system must be completely or partially replaced, restored or modernized. The work is carried out in the warm season, after the heating season. Major repairs are planned in advance - a list of works is drawn up and contractors are selected through a tender.

The full list of work on overhaul of heating systems includes:

Replacement or repair of risers, in-house pipelines and connections
Cleaning of scale and corrosion of pipes and equipment
Replacement or repair of shut-off valves
Repair and reconstruction of thermal units, including changes in thermal power, change of coolant, changes in technological processes
Replacement or repair of heating devices: pumps, valve drives, starting equipment, including automatic control and thermoregulation systems
Commissioning works

Is replacing radiators in apartments included in the list of major repairs?

Funds allocated for capital repairs are used to repair and replace only common property. Heating radiators in apartments are the property of the apartment owner, so they are replaced at your own expense. But, according to the position of the Ministry of Construction of the Russian Federation (Letter dated April 1, 2021 No. 9506-ACh/04), confirmed by the decision of the Supreme Court of the Russian Federation, heating radiators that do not have shut-off devices (fittings) on branches from risers also belong to common property. In addition, the composition of the common property of an apartment building can be determined by the owners and enshrined in the management agreement for the apartment building.

clause 1. In accordance with the order of the Housing Committee of St. Petersburg dated June 30, 2020 No. 600-r “On amending the order of the Housing Committee dated December 31, 2019 No. 2421-r”, in 2021 in the Kirovsky district of St. Petersburg it is planned to carry out major repairs of the general property of apartment buildings at 96 addresses (143 objects) for a total amount of 610,358,675.73 rubles, of which 21 objects are major repairs of the heat supply system for a total amount of 252,436,384.46 rubles.

As of 09/16/2020, for 2 objects, completion is from 50% to 70%, for 4 objects, completion is from 70% to 90%, for 1 objects, completion is from 90% to 100%, and for 14 objects, completion is 100% .

Problems and solutions

Is it possible to carry out minor repairs to the water supply in an apartment yourself?

In general, repair work must be carried out by the organization servicing the building or by a third party after concluding a contract with it. However, an apartment owner with minimal experience in plumbing work can easily fix a number of minor faults with his own hands. Let's look at a few typical repair scenarios.

Fistula on the eyeliner or riser

Symptoms: water leaking on a smooth section of a steel water supply pipe.

Fistula on the connecting sleeve of the cold water riser

Reason: through corrosion of the pipe (most often along a welded joint or longitudinal seam).

Reference: all water and gas pipes produced in accordance with GOST 3262-75 are electric welded. They are made by rolling up a strip (flat tape) and welding the longitudinal seam.

Remedy: installation of a repair clamp. It can be replaced with a rubber gasket for the faucet, pressed against the defective section of the pipe, cleaned of rust and paint, with an aluminum clamp or binding wire.

Installation of a bandage made of an aluminum clamp and a rubber gasket

Leak along the drain

Symptoms: water drips from the lock nut or long thread on the drain after the valve (at the entrance to the apartment, hard supply to the sink mixer or drain tank).

Causes:

Rotting or burning out of the organic fiber of the winding;
Mechanical impact on the threaded connection;
Through corrosion of the thread of the drive. At the thread cavities, the pipe wall has a minimum thickness.

Leaking corroded pipe

Remedy:

Rotten or burnt out winding is replaced with a new one. To do this, when the valve at the water supply inlet to the apartment is closed, it is necessary to unscrew the lock nut 3-4 turns, remove the remnants of the old winding, wind several turns of a new one and tighten the lock nut with moderate force;

Hint: as a winding, you can use polyester thread with silicone (for example, Tangit Unilok) or sanitary linen impregnated with silicone or quick-drying paint. It is not advisable to use FUM tape: a connection wound with it will leak with minimal reverse movement of the locknut.

Sealing thread for thread

If the connection is loosened by mechanical force, it is enough to tighten the locknut with moderate force;
The corroded lead is replaced with a new (preferably brass) lead of the same length. To replace it, you need to turn off the water, fit the locknut and coupling along the long thread, unscrew the drive from the valve and reassemble the connection in the reverse order.

Assembling the connection with the drive. 1 — drive, 2 — supply after the valve, 3 — coupling, 4 — lock nut

Weak water pressure at one tap point

Symptoms: low pressure of cold or hot water on one of the faucets.

Reason: clogging of the faucet seat or liner in front of the mixer.

Remedy: turn off the water, unscrew the faucet and clean the seat and the connection in front of it through the hole in the mixer body with a thin cable.

Access to the blockage in the line in front of the mixer can be obtained by unscrewing the faucet

Low water pressure throughout the apartment

Symptoms: low pressure of hot water or hot water at all water points.

Reasons: clogged coarse filter at the entrance to the apartment; blockage or accumulation of deposits in the water supply line before or after the valve.

Filters are located at the water inlet into the apartment and serve to protect meters and plumbing from sand and rust.

Remedy: cleaning the filter after turning off the water using the valve on the inlet or cleaning the inlet itself. In the latter case, you need to shut off the water along the riser. The cable is inserted into the connection through an opened screw valve, and in the case of a ball valve, through an unscrewed connection or an opened filter.

Valve stem leaking

Symptoms: Water flows down the screw valve stem.

Leak location

Cause: worn out O-ring or seal.

Remedy: Open the valve all the way. In this case, the thread of the rod should press the oil seal from below, which will stop the leak. If this does not help, refill the oil seal.

Here is the order of work:

Close the valve;
Remove the lamb;
Unscrew the nut on the rod;
Use a screwdriver or pliers to remove the oil seal;
Place 3-5 threads of graphite seal under it and seal it with a screwdriver;
Reassemble the valve in reverse order.

How does the MKD heating system work?

The heating system is a set of technical elements designed to receive, transfer and transmit heat to all rooms in which the temperature needs to be maintained at a certain level. This system consists of:

heat source,
heating pipes,
heating devices.

Types of heating systems differ in the type of heating source, range, operating mode, wiring method, and so on.

Find out in more detail what the heating system of an apartment building is.

System test

Hydraulic testing of the system is performed upon completion of flushing and, as a rule, confirms the successful repair of heating systems. Such tests should only be carried out during warm months. First, all shut-off valves are opened: this equally applies to the valves that are located on the air collectors. Then a special hydraulic press is connected to the heating system - it supplies water.

Filling the system with water must occur slowly, otherwise air will remain there. When liquid appears in the air collector valves, they must be closed. Next, the hydraulic press releases the specified pressure, which should be 1.25 times greater than the working pressure. After 5 minutes, the indicators are checked: the pressure should not drop by more than 0.02 MPa.

If everything went well, and tests showed that there is no need for repairs, the heating system is preserved and put back into operation in the house only at the beginning of the next season. Preservation consists of filling pipelines and other areas with clean working fluid, which is taken from the heating network.

Specifics of the overhaul

Heat supply overhaul consists of a whole range of the following operations:

Replacement and restoration work is, as a rule, ordinary (for example, insulating pipes or reinstalling shut-off devices) and complex (laying a pipeline, eliminating equipment defects). Our company’s team of specialists will take action to eliminate heat supply faults and modernize it, increasing the power, reliability and efficiency of the system;
At the initial stage, the heating complex undergoes a visual inspection. Our experts assess the state of affairs taking into account the client’s wishes. Information is prepared for the customer about what specific equipment needs to be changed in order for the heat supply to operate much better. During a detailed inspection, a work plan is drawn up, which is given to the client to familiarize himself with;
When carrying out restoration operations, the characteristics of the heating system are taken into account, as well as the engineering specifics of the service facility. Recommendations are given on filling out an advance application for the necessary work in order to quickly overcome all repair stages.

Leave a request for repair of heating batteries

Heating radiator repair

Repair of radiator batteries usually consists of several stages:

inspection to identify the location of a leak or other breakdown;
preparing the necessary tools and consumables, including steel cable, sealant, cold welding compound, and a container for collecting water;
cleaning the damaged area from paint residues, removing the winding and anything that may interfere with work;
treating the leak site, sealing and fixing a section or individual connection.

We should also talk about the repair of aluminum heating radiators in the apartment. Unlike cast iron or bimetallic batteries, installing sections in them is much simpler. Therefore, as part of the repair work, it is possible to remove some of the heating elements or add new ones. Damage that occurs on aluminum is best eliminated by argon welding, which is recommended to be performed only with the participation of specialists.

Repair of heating radiators in all areas of Moscow:

Service organizations

In apartment buildings, the responsibility for maintaining the heating system falls on the shoulders of the management company. The latter has the right:

carry out all work by its employees;
attract contractors.

Concluding a contract for system maintenance

To carry out maintenance work on the heating system, a special contract must be concluded. This document contains the following information:

list of services provided, their individual components and characteristics;
turnaround time;
cost of services;
rights and obligations of the parties;
liability for violation of the provisions of the agreement.

The agreement can be concluded once or re-signed periodically. This document is a guarantee that the heating system will work efficiently.

Who is to blame for the system malfunction?

All accidents associated with the heating system can be divided into intra-apartment and intra-house. This separation allows you to determine who is to blame for the problems.

Legally, responsibility for the heating system rests with consumers of services and the companies that provide them. The management company is fully responsible for the in-house system, so the blame for the accident falls on this organization.

Limits of responsibility between owners and management companies

Owners of housing in apartment buildings must ensure the safety of not only their apartment, but also common property. By signing the contract, each tenant agrees to these conditions of living in the apartment building.

And yet, many people believe that since the batteries are in their apartment, they belong to them by right of ownership. However, the heating system along with the radiators is included in the structure of the common property of the house. Therefore, only management companies are involved in their repair and replacement.

Cost of replacement as part of a major overhaul

The legislation of the Russian Federation places the burden of payment for major repairs of apartment buildings (including replacement of heating) on apartment owners.

Is this included in the payments for major repairs?

Since 2014, residents must transfer funds monthly to a special fund, from which capital repairs are subsequently paid (Article 169 of the Housing Code of the Russian Federation). The amount of contributions for each owner is calculated individually by multiplying the tariff established in the region by the total area of the apartment. The law does not provide for a separate fee for major heating repairs.

Both current and major heating repairs are similar in that they are carried out as planned, but differ in scale and goals. Central heating elements that are in common ownership of the apartment building residents are subject to restoration work. The ultimate goal of the repair is the safe operation of the heating system.

A major overhaul of the heating system in an apartment building becomes relevant when there are frequent complaints from residents about the unsatisfactory quality of the services provided, in case of various leaks, or due to the old age of the equipment. Depending on the expected problems, various types of work are performed, the main task of which is to maintain the heating unit in proper condition.

Flushing the heating system in an apartment building

At whose expense is it possible to replace heating pipes in case of an accident?

The battery burst, the neighbors were flooded - who is to blame? What to do when the heating has become unusable and the neighbors have suffered? Where to find the culprits? First you need to find out whose fault the accident occurred. Who is to blame: the owner of the apartment or the management company that monitors the condition of the heating pipes of the entire house. If the heating breakthrough occurred due to the fault of the owner, then he will compensate for the damage to the neighbors flooded from below.

If it is the fault of the management company, then all expenses for repairing the premises will be borne by it. The Housing Code imposes obligations on the apartment owner to keep the property in good condition and monitor the pipes. If necessary, he must make repairs. If the pipes are in poor condition, you need to contact the housing office and call a specialist. The invitation of a specialist must be officially formalized. It is necessary to fill out a request, which will be registered and a repair time will be set.

Types of system maintenance work

According to Appendix 1 to the Methodological Manual for the Maintenance and Repair of Housing Stock MDK 2-04.2004, maintenance of communications, technical devices and premises consists of the following list of works:

conservation and re-preservation;
adjustment of taps, valves, gate valves;
adjustment and packing of oil seals;
compaction of squeegees;
system check;
descaling;
turning off radiators in case of leakage;
washing and cleaning of constituent components;
draining/filling the system with water;
eliminating air jams;
strengthening pipelines.

If an accident is detected, the damaged fittings are repaired and replaced.

Self-replacement

Not many apartment owners wait for major repairs or an emergency. Many people decide to replace old equipment with modern equipment at their own expense. There are several options for notifying the management company of your intentions:

Phone call to the building management. The dispatcher, whose number is on the bills for utility bills, will give a substantive answer when it is possible to carry out the necessary work. In this case, it is worth asking the dispatcher to introduce himself. This usually speeds up the process.
Internet sites where you can present a problem and ask for it to be solved. Not all management companies provide this opportunity, of course, but many already do.
The usual way is to go to the management company and leave a request to replace the existing radiators with bimetallic ones (or others) throughout the apartment. It is better if several residents submit such applications.

Artist selection

Replacement of heating devices can also be carried out by third-party certified plumbers. On the one hand, it makes more sense to order this service from a familiar company, which in any case will turn off the risers. On the other hand, as experience shows, it turns out to be more expensive. When making a decision, you must remember that hiring even very competent plumbers will not relieve the apartment owner from responsibility in the event of problems with the system as a whole. Therefore, it is more reliable to replace heating batteries in an apartment through the housing office. And remind the management company employees of this right. For example, the choice of new heaters is up to the resident. And he chooses them to his taste, taking into account his interior. Exceptions may be made to technical specifications, which must be agreed upon with professionals - UK plumbers.

Having concluded an agreement with a certain management company, you involuntarily gain confidence in its specialists in the field of housing and communal services. Therefore, it is easier to immediately be persistent and get the desired equipment replaced. A huge advantage of cooperation with the management company is the confidence that new heating devices will be approved, registered, and you won’t have to wait for any claims regarding their installation.

Housing and communal services in Russia.

The battery, which is a common property of the house, must be replaced by the management company at the expense of the money that you regularly and monthly paid and are paying under the article “maintenance and repair of the home.” Here is what is determined by the laws and rules in this regard: (hereinafter - abbreviated excerpts without changing the meaning of the document ):

A. RULES FOR MAINTENANCE OF COMMON PROPERTY IN AN APARTMENT BUILDING (approved by the Resolution of the Government of the Russian Federation of August 13, 2006 N 491):

“...2. The common property includes: ... e) mechanical, electrical, SANITARY and other equipment located in an apartment building outside or inside the premises and serving more than one residential and (or) non-residential premises (apartment);

6. The common property includes an intra-house HEATING system, consisting of risers, HEATING ELEMENTS, control and shut-off valves, collective (common house) heat energy metering devices, as well as other equipment located on these networks...”

B. MDK 2-04.2004 “METHODOLOGICAL MANUAL FOR MAINTENANCE AND REPAIR OF HOUSING STOCK” (approved by order of the USSR State Construction Committee in 2004):

LIST OF WORK INCLUDED IN THE FEE FOR HOUSING MAINTENANCE

LIST OF WORK INCLUDED IN THE PAYMENT FOR REPAIR OF HOUSING (current repairs) ... 1. Central HEATING: Replacement of individual sections of pipelines, sections of heating devices, shut-off and control valves; ... restoration of destroyed thermal insulation.

B. “RULES AND STANDARDS FOR TECHNICAL OPERATION OF HOUSING STOCK” (approved by the Post of the State Construction Committee of the Russian Federation dated September 27, 2003 No. 170):

“... II. ORGANIZATION OF MAINTENANCE AND CURRENT REPAIR OF HOUSING STOCK

LIST OF WORK RELATED TO CURRENT REPAIRS... 11. Central heating Installation, REPLACEMENT and restoration of functionality of INDIVIDUAL ELEMENTS and parts of elements of internal central heating systems, including house boiler rooms.” Anastasia! In fact, to replace an EMERGENCY radiator, the management company must buy a new one at the expense of funds “for the maintenance and repair of property,” but for this it is necessary that the appropriate paper be drawn up - an act on the inspection of the radiator, the discovery of an irreparable defect on it and the need to replace it, signed You and the management company employees, which, of course, they won’t do.

Anastasia! Politely shove the above text under the noses of the impudent robbers from the Criminal Code and threaten them to send a letter of complaint to the prosecutor's office about their extortion.. And if the Criminal Code refuses to replace the battery at the expense of funds for the maintenance and repair of common property, write letters of complaint to the State. housing inspection, the city administration and the prosecutor's office. Good luck to you!

What types of repair work are there?

There are three types of repair work on heating systems:

Let's look at each of the presented types in more detail.

Maintenance

Current repair work allows you to identify and eliminate minor faults, carry out routine checks of fittings, their installation and revision. They are carried out once every three to four years and include:

monitoring the coolant, replacing it if necessary;
comprehensive flushing of the system;
inspection of shut-off valves in the elevator heating unit and on risers;
replacement of risers, elimination of minor leaks in pipes and welds;
rewinding locknuts on risers;
valve repair;
replacing the spacer wedge;
inspection of cast iron valve;
regular heating system maintenance.

Find out in more detail what the current renovation of an apartment building is.

Major renovation

Overhaul involves complete or partial replacement of equipment. This activity includes replacement work:

risers and heating connections;
heating devices;
elevator unit or shut-off valves;
heating spills.

Before drawing up a contract for major repairs, the management company must create a defective list with an indicative list of work and consumables, and then announce a tender for the supply of equipment and repairs.

An agreement is concluded with the winner of the competition indicating the services provided, their cost, payment procedure and other important points.

Find out how major renovations of apartment buildings are carried out.

Emergency repairs

Emergency work is carried out when there is a need to restore the functioning of the heating system after serious damage.

Emergency repairs may be required in the following cases:

fistula in the heating pipe;
lack of heating through the riser;
locknuts in front of the radiator are leaking;
leakage between sections of heating batteries;
inability to close the flush valve after flushing;
defrosting of access heating.

Find out more about what the housing and communal services emergency service does.

Maintenance

In preparation for the heating season, specialists from housing maintenance offices must carry out inspections of heating systems annually. But due to lack of personnel and funding, such events are often simply ignored. As a result, repair work can begin only after a written request from the residents of the house to higher authorities or after receiving a complaint. In the latter case, a commission is created and the following types of heating system repairs are performed:

checking the operation of the elevator unit of the building and then resetting all valves and gate valves. If necessary, these parts are replaced with new ones. This can also include replacing oil seals and lubrication of rods;
during the inspection of shut-off valves, worn gaskets are replaced;
When repairing valves, spacer wedges are restored by grinding in the mirrors, replacing the pressure rings and restoring the rods. Purchasing new valves is not rational, they are very expensive, so this part will be repaired until the last minute.

We recommend: How to repair heating in an apartment?

A cast iron valve by its appearance will never indicate the need for repair, therefore, during routine repairs, the following types of work of a similar plan are carried out:

checking the locking mechanisms of risers. If these elements are not working properly, then at the slightest damage or leak, it will be necessary to reset the entire house, and this is dangerous during winter frosts and can result in freezing of the system in many areas of the entrance;
After certain periods of time, it is also necessary to check the fastening of the locknuts. This measure is necessary due to the fading of technical flax, and houses in which sealing was carried out with materials that are not afraid of fading were built in the last century.

But the main work of the team for routine heating repairs in an apartment building is to fully service the system, start it up and eliminate air jams during heating start-up, if residents from the upper apartments cannot do this on their own.

Carrying out work to ensure heat supply in apartment buildings

The main regulations that should be relied upon when resolving issues related to the restoration of the heating system:

Decree of the State Construction Committee of the Russian Federation No. 170 “On approval of the Rules and Standards for the Technical Operation of the Housing Stock” (hereinafter referred to as PG of the Russian Federation No. 170) defines the types of repair work, the rules and regulations for their implementation, the list of works and who carries out them.
Decree of the Government of the Russian Federation No. 491 (hereinafter referred to as RF PP No. 491) defines the “common property” of MKD. Details the elements to be repaired depending on the degree of wear. Regulates organizational issues.
The Housing Code (hereinafter referred to as the Housing Code of the Russian Federation) explains the sources of financing for repairs and the features of contractual relations.

In accordance with clause 1.8 of the RF PG N 170, the following types of repairs can be carried out to maintain engineering systems in proper condition:

Let’s determine what their difference is, and what conditions create the prerequisites for each type of repair.

Capital works

Prerequisites for carrying out a major overhaul of the heating system:

development of the service life established by the standards (service life of steel heat supply communications - 25 years);
a situation arises when individual space heating elements that are in common ownership violate the established maximum permissible reliability characteristics and create a safety hazard (clause 21 of RF PP No. 491).

What is included in the work to restore heat supply during a major overhaul (clause 7.2 STO NOSTROY 2.33.120-2013):

Complete or partial replacement of intra-house heat supply lines, including risers, branches from risers into the apartment.
Replacement of control and shut-off valves, including on the branches of risers to heating devices in apartments.
Replacement of radiators in common areas (entrances, basements).
Selective replacement of heating radiators in residents' apartments - in the absence of shut-off devices.

The last point of the above list is the most controversial. The fact is that heating radiators, in accordance with clause 6 of RF PP No. 491, are classified as common property, that is, those that serve more than one premises (Article 36 of the RF Housing Code). This means that residents who carry out repairs can theoretically qualify for a free replacement.

Replacing batteries in a finished apartment

Replacing the battery while preserving the repairs made is a fairly common task we encounter. Of course, it is much more convenient when the order of finishing the room is such that heating devices are installed at the rough finishing stage. But it happens that there is no way to do this at that moment, or the apartment was purchased already finished, and the batteries are still old. Therefore, in this article we will discuss how to install heating radiators efficiently and without spoiling the finish.

The most common places that need to be protected from external influences are the floor, baseboard, wallpaper and window sill. Furniture must be moved at least 1.5 meters from the installation site in advance.

When installing radiators in a renovated apartment, there are two types of work that can harm it:

1. Dismantling the old battery and the pipes leading to it using an angle grinder (grinder).

2. Installation of a new battery using electric arc welding.

When dismantling old radiators, pipes are cut off from the heating riser (if the riser is external) at the required height in order to make a new supply line; if the riser is in the wall, then the pipes are cut in the immediate vicinity of it.

When cutting pipes with a grinder, a huge number of directed sparks fly, which leave points on the surface located at a close distance from the cutting site. These sparks quickly go out, so it is not necessary to install any fireproof materials; in this situation, a regular sheet of plywood or chipboard will suffice. At the same time, if this is not done, the sparks will definitely leave black spots on the fresh wallpaper. And nothing can remove these black spots; you will have to re-glue this section of wallpaper.

When installing batteries, the temperature at the welding sites is significantly higher, so materials to protect the finish must be fireproof.

To maintain repairs, you need a distance between the pipe and the wall to accommodate them. This distance must be at least 3 cm. Our welder places paronite sheets (melting point 500 degrees) and asbestos fabric near the welding site, that is, directly between the pipe and the wall. But in addition to this, it is necessary to put additional things around this place to avoid accidental sparks. The same sheets of plywood or chipboard are very suitable for this, but you need to put a wet thick rag (old waste fabric) on top of them. The window sill can also be covered with a wet thick rag. When replacing a heating riser under the ceiling, it will not be possible to keep the corner at the top in the same condition. Since it is technically impossible to fix all these materials at height.

Pressure testing of the heating system

Some measures, for example, pressure testing, make it possible to detect malfunctions in a timely manner. First, let's discuss what pressure testing of a heating system is. This term refers to a set of actions aimed at monitoring the condition of heating equipment and its suitability for use.

A hydraulic test is a test of the heating system for leaks.

For this purpose, excess pressure is specially created, which is brought as close as possible to the limit. The latter is determined by calculation. Next, they simulate a water hammer that can occur in the system at any time.

Pressure testing must be carried out:

upon completion of installation during commissioning of the system;
after repair of heating devices;
in case of replacement of part of the pipeline;
in preparation for the heating season.

It is worth mentioning how pressure testing of a heating system in an apartment building is carried out. This process consists of several stages:

Filling the system with water.
An increase in pressure in it.
Monitoring the indicators of devices that measure pressure.
Inspect for leaks.
Troubleshoot if detected.
Drawing up a certificate of pressure testing.
Filling the system with water.

Pressure testing is carried out by an enterprise, institution or organization operating the heating system.

Why flush the heating system?

Scale accumulates on the walls of the system, which can cause problems in the operation of the equipment. In particular, it leads to pipe wear and reduced heat transfer. Flushing the heating system in an apartment building is designed to prevent negative consequences.

Due to the slow movement of the coolant, batteries and horizontal sections of pipes become silted over time. Without flushing, the speed of water circulation decreases, and mechanical wear of pipes and fittings, on the contrary, accelerates.

In apartment buildings, flushing is carried out if underheating of individual batteries is detected.

It is important to know not only when to carry out this activity, but also how to properly flush the heating system. Thus, the following conditions must be taken into account:

For flushing, you can use tap, process or network water;
the procedure must be carried out until the water becomes clearer and dirt, scale and sludge begin to come out of it;
in an open system, you should first do a flush, then disinfection and another flush. This is repeated until the water meets drinking standards.

Regulatory documents require this procedure to be carried out annually.

Different washing methods

There are several ways to flush a home heating system:

Mechanical. Its main purpose is to clean the radiators from dirt and the inner surface of the circuit from scale. Preliminary dismantling of batteries and cleaning of radiators and pipes will increase efficiency.
Hydrodynamic. To carry out the procedure, you will need special equipment. Water is supplied not from a tap through a hose, but using a high-pressure pump. This allows you to quickly deal with mud and salt deposits.
Chemical. To avoid mechanical interference, chemical compounds/solutions are used. Dismantling the radiators is not necessary. This method is suitable if you need to restore the functionality of a heating system that has been in use for decades, as well as when it is necessary to remove deposits from steel pipes.
Hydropneumatic. The essence of this method is to supply air inside the heating circuit under high pressure. This goal is achieved by using a compressor.
Electrohydropulse. The method is based on the use of electrical impulse energy. It is aimed at destroying salts deposited on the walls of the pipeline. The pipes themselves are not affected in any way.

Classification of central heating systems

The variety of central heating organization schemes that exist today makes it possible to rank them according to certain classification criteria.

By thermal energy consumption mode

seasonal. provision of heat is required only during the cold season;
year-round. requiring constant heat supply.

By type of coolant used

water - this is the most common heating option used to heat an apartment building; such systems are easy to operate, allow you to transport coolant over long distances without deteriorating quality indicators and regulate the temperature at a centralized level, and are also characterized by good sanitary and hygienic qualities.
air - these systems allow not only heating, but also ventilation of buildings; however, due to the high cost, such a scheme is not widely used;

Figure 2 – Air circuit for heating and ventilation of buildings

steam - considered the most economical, because small-diameter pipes are used to heat the house, and the hydrostatic pressure in the system is low, which makes it easier to operate. But such a heat supply scheme is recommended for those objects that, in addition to heat, also require water vapor (mainly industrial enterprises).

According to the method of connecting the heating system to the heat supply

independent. in which the coolant (water or steam) circulating through the heating networks heats the coolant (water) supplied to the heating system in the heat exchanger;

Figure 3 – Independent central heating system

dependent. in which the coolant heated in the heat generator is supplied directly to heat consumers via networks (see Figure 1).

According to the method of connection to the hot water supply system

open. hot water is taken directly from the heating network;

Figure 4 – Open heating system

closed. in such systems, water is drawn from a public water supply, and its heating is carried out in the central network heat exchanger.

Types of repair work of heating systems

Types of heating repairs in an apartment building can be divided into the following categories:

Maintenance. The main part of the search for problems for this type of work is carried out during routine inspections of equipment in preparation for the heating season. During the period of special audits, minor defects in the system are identified, which are corrected taking into account the technical characteristics of the heating unit;
major heating repairs are carried out after a certain period of operation of the building and include the dismantling and installation of new components instead of failed units. Here pipes, radiators, valves and other elements of the system can be changed;
emergency repair. It is carried out urgently and includes work to eliminate emergency situations. This may include measures to eliminate various leaks that may appear as a result of ruptures in riser pipes, elevator plugs, or freezing of a piece of the system.

Preparatory work for the heating season is carried out during the shutdown of the system during the summer break in equipment operation. Water is drained from the structure, which makes it possible to carry out repairs without harm to the residents of the house.

Heating system of an apartment building

About autonomous heating

An autonomous heating system for an apartment building is the dream of many apartment owners, but the process of switching to independent heating is difficult and expensive. This includes lengthy legal hassles and a technical solution to the issue - the correct selection of equipment, installation and commissioning. And the problems associated with the technical implementation of the project are much simpler.

Autonomous boiler room of an apartment building

The market for household appliances, including heating, offers a wide range of boilers, radiators, pipes and all kinds of fittings, and in every city there are several dozen specialized companies working in this direction. The organization will not only do all the installation and configuration work, but also issue all the necessary acts and permits. But the cheapest thing, of course, is to install a heating boiler and install the pipes yourself.

Basic documents required to connect the autonomous heating of an apartment building yourself:

Diagram of violations in the operation of the DSP

Having completed all the certificates and acts, you can begin to put your dream into practice and cut off the radiators and pipes of the house or apartment DSP wiring. And don’t forget to shut off the heat pipe input and seal it. In houses to which a central heating system is connected, this is easier to do than in high-rise buildings - in apartment buildings, pipe risers were laid throughout the premises, and to dismantle them, you will have to obtain the consent of the neighbors above and below, and the continuation of the cut pipes will have to be looped.

Important: Risers that are not connected to your radiators, but pass through the apartment, are considered a heat source. In order not to pay for their thermal energy to the housing office, the pipes should be properly insulated - this way you can prove that you do not use central heating

What is washer system

It often happens that in a house located next to a boiler room, the radiators become so hot that residents are forced to open windows, and residents of distant buildings freeze. To avoid this, technicians take measures to distribute heat evenly between consumers.

Washing the heating system of an apartment building is the process of installing special washers with holes of the required caliber on the branches of heating networks. Thanks to this, nearby buildings receive less heat, part of which is sent to distant apartment buildings.

Using such a system allows you to reduce:

carrier flow through pipes;
number of boilers used;
consumption of electricity and fuel.

At the same time, the costs of this procedure are low.

Repair of heating system boilers in Moscow and the region

This is the main and most complex component of the entire heating supply of a building.

To repair them, it is important to attract the right, qualified specialist who can quickly restore functionality and do it efficiently, so that this key element does not fail for a very long time. The best option after repair would be regular preventive inspection, which will allow it to operate uninterruptedly and avoid accidents in the future.

To do this, it is advisable to describe the possible causes of the breakdown when calling us, this will speed up the repair process.

When repairs may be needed:

When the temperature of the coolant decreases
When the unit responsible for controlling the boiler is turned off
If leaks occur
If there is an external influence on the system, be it overheating or mechanical influences, some voltage surges and electrical failure

Often breakdowns occur due to insufficient quality fuel used for heating. If this is the case, then when you examine the heating unit and nozzles you will see that they are clogged.

Household heat meters

establishes the obligation to equip apartment buildings with common house meters for water, electricity, heat and gas. They are usually installed in technical rooms (basements, utility rooms).

Using counters, you can record the amount of resources spent. At the same time, not only individual meters are installed for thermal energy, but also multi-tariff ones, which allows you to pay cheaper at night rates.

The management company is responsible for the maintenance of common house appliances. It monitors that utility bills correspond to the amount of resources consumed.

Emergency repair

The name alone makes it clear that emergency work is carried out in situations where urgent assistance is required. Among the most common problems of this kind are:

no riser heating. First, the locking mechanisms and valves are inspected; sometimes uncoordinated actions between residents and utility services lead to them simply being closed;
There is no full water supply to the system. The cause may be an extra object getting into one of the pipes. It could be a piece of rust or slag stuck on a bend in the pipeline. After its elimination, the air is vented from the upper floors, and the system is put into operation;
leak detection. If there is no threat of destruction, then the brigade’s responsibilities include the task of applying a fastening bandage to eliminate the leak. Next, welding work will be carried out by maintenance specialists.

When the system freezes, the entire riser is turned off and the location of the problem is carefully calculated; after it is detected, the pipe is heated to remove the cause of the malfunction.

How much does the service cost and who pays for it?

In accordance with the legislation of the Russian Federation, the cost of installing meters falls on the shoulders of the owners of a residential building. Often they are initially included as part of the fee for the maintenance and repair of residential premises or as part of mandatory payments. The expenses of each owner are proportional to his share in the common property right.

Many people are also interested in how much it costs to pressurize a heating system in an apartment building. Each company sets its own tariffs. As a rule, the area of the building is taken as a basis, on which other parameters depend:

length of pipelines;
number of heating devices;
thermal performance;
the cost of the work itself.

List of works included in the overhaul

Due to monthly financial savings accumulated from contributions from residents of apartment buildings, it is possible to carry out a fairly impressive list of repair, restoration and installation work, which is considered a major overhaul.

As stated in the legislation, a major overhaul of a house involves the implementation of work regulated by the legislator to eliminate various faults and worn-out structural elements in the house, classified as common property, including various works on restoration, replacement of structures and systems of the house to improve the operational properties of the common property of housing rights holders in an apartment building .

One of the basic directions when carrying out major home repairs is the repair of walls and facades, which allows:

repair and insulate house facades and plinths;
repair and, if necessary, glaze balconies and loggias;
change window and balcony fillings to more soundproofing options;
replace or repair gutters;
repair house fire escapes;
change or repair the roofing of a house;
arrange canopies over loggias, balconies, entrances to entrances, basements;
repair the blind area;
repair the external walls of common building elevator shafts.

The next important direction in the field of overhaul work is the restoration of the proper condition of the basements and foundation of an apartment building. For these purposes, the following work can be carried out, financed, among other things, from mandatory regular contributions from apartment owners:

house foundation repair;
antiseptic treatment of structural elements of multi-apartment buildings;
repair of entrances to basement premises;
sealing places where there is an intersection of engineering systems with a foundation element, etc.

In addition to the listed work, capital repair funds can finance repair work related to restoring the proper condition of attics and roofs, namely:

replacement, repair of attics and roofs, their fire protection treatment;
treatment of wooden structures with antiseptics;
repair or replacement of pallets;
normalization, restoration of temperature and (or) humidity conditions;
sealing, repair work for repairing air ducts, flues and other similar systems;
replacement and repair of parapet gratings;
work on replacement, repair of internal drainage elements, etc.

During major repair work, restoration of staircase structures can also be carried out with the replacement of steps, fences of house landings and other work.

Quite a significant part of the repair work performed during home overhauls is associated with restoring the condition and improving the entrance areas and door fillings. The considered category of work financed from capital repair funds includes the following activities:

change and repair of access lighting;
replacement and repair of access entrance doors;
work on changing and repairing doors in garbage chambers;
strengthening, restoration, partial replacement of stair steps, repair of the entrance platform, etc.

Major repairs include replacement, restoration, and improvement of in-house engineering systems in apartment buildings. With the help of capital repairs you can:

1. Repair central heating:

replace and repair risers, house pipelines, connections to public heating systems;
install shut-off valves;
install heating devices with attached and built-in thermostats with automatic mechanisms;
replace or repair thermal curtains;
reconstruct panel control systems;
establish the functioning of heating systems;
install automatic balancing valves on heating structures, etc.

2. Repair and improve the ventilation systems of the house:

change ventilation grilles;
clean ventilation systems, etc.;

3. Ensure the organization of hot and cold water supply systems:

change and repair pipelines if they belong to common house systems;
install shut-off valves;
change the pipe layout;
install meters, etc.

4. Carry out repair work on home sewerage and drainage systems.

5. Repair other systems in the house (internal gas supply, electrical equipment, fire protection systems).

Major repairs may also include work to restore the functions and improve garbage chutes, elevators, including ensuring the accessibility of public elevators for the disabled, as well as interior home decoration (when the appearance of the decoration was damaged due to repair work on the house) and landscaping of the yard.

Thus, the overhaul includes a fairly extensive list of repair work related to the improvement of the common living space. Thanks to the accumulation of financial contributions from Russian citizens in the fund for major repairs, over time it is expected to significantly improve the housing stock in most Russian regions.

Accordingly, paying fees, perceived by many Russians as just another “extortion” from public utilities, also has its positive aspects. In addition, citizens in this situation have no choice: paying mandatory contributions for major repairs is the responsibility of all owners of apartments in an apartment building. The legislator provides only 2 exceptions:

If housing, in particular, a house, is recognized as unsafe and subject to demolition;
If the land under the house is required for municipal needs.

Types of overhaul of the heating system

As a rule, there are several types of heating restoration measures in an apartment building and they can be divided into three types:

scheduled repairs.
The main actions for this category of repairs are carried out during routine inspections of the heating supply to prepare for the heating season. During special checks, minor violations in the equipment are identified, which are eliminated due to the technical features of the heating unit;
overhaul
is carried out after a certain period of operation of the structure and entails the disassembly and installation of updated devices to replace the failed ones. Usually pipes, valves, batteries and other parts must be replaced. Sometimes relatively new heating systems are replaced, in which undetected faulty components and disturbances caused by a malfunction of the thermal energy source are found;
emergency repair due to an accident
. It is carried out urgently if necessary, and covers work to eliminate emergency situations. This includes operations to eliminate various leaks that could occur due to a break in the pipeline in the riser, elevator plugs, or freezing of individual pipes.

Preliminary preparations for the heating season are carried out during the period when the system stops functioning during the summer holidays. Water is released from the structures, which allows for major repairs without harm to the population of the apartment building.

Replacing heating risers in an apartment

Over time, every owner of a living space in a high-rise building faces the need to carry out the work mentioned in the title of a real publication.

This event is quite expensive. Due to this, it is absolutely natural to want to save money by entrusting the payment for the work to a third party, for example, a homeowners association or housing department. However, is this always realistic?

In what options and by whom do risers in an apartment be replaced?

The need to replace heating risers appears in three cases: if a cap is performed. repairs, work is underway to replace the interior, its subsequent work is not possible for technical reasons. The last reason is typical for old houses, since the service life of the risers in them is close to critical. Very often in the above situations, the heating riser is replaced with polypropylene.

This legislation states that replacing the heating riser in an apartment is the responsibility of housing and communal services, for example, if we are talking about general building communications to which expanders are connected to apartments (attic and basement, entrances). The specified work is paid for by all owners. Moreover, the period for replacing heating risers in these circumstances is determined at the legislative level.

If, for example, the house in which your living space is located belongs to the housing department, and the risers need to be changed immediately (an emergency condition has appeared), housing department employees will replace them. It is important to take into account that all pipes up to the shut-off valve, the first one at the entrance to your living space, common property, everything located behind it must be repaired at the expense of the tenant.

The management company and the homeowners' association are entrusted with the responsibility for carrying out maintenance and repair work at the facilities (see government order No. 491, dated 08/13/06, and also order No. 170, adopted by the State Construction Committee of Russia on 09/27/03).

If you live in an apartment that you rent under a social rental agreement, then the risers in it are also required to be changed by employees of the management company or HOA, on their own and at their own expense. But if your housing is privatized, then you will need to complete these works in full at your own expense.

Rules for carrying out work on replacing heating risers

If you intend to change the riser from the valve, then you will not need any permits. In this case, it is allowed to replace the heating risers in the apartment with your own hands. If the valve itself needs to be changed, then permission from the housing office is required, which is issued on a paid basis.

A very good solution when performing the above work is considered to be a one-time replacement of the heating riser with polypropylene on all floors at once (the entire span). But, in many cases, this request cannot be fulfilled. For some neighbors, the work is considered unnecessarily expensive, others have already changed everything in their own apartment, and others are quite satisfied with the condition that you have at the beginning of the renovation work.

According to the existing rules for carrying out work, they must be carried out in the following order:

The system is shut off and water is drained from it. This work is performed primarily by a housing mechanic. If the work is emergency, the riser will be closed free of charge. In any other situation, you will need to pay a state fee.
An angle grinder is used to cut out the outdated riser pipes in the apartment. In this case, it is necessary to take into account the technology of further work.
If the riser changes along the entire span, then the pipes are cut with a similar calculation so that they can be comfortably pulled out of the ceiling;
The installation locations for new radiator designs are being outlined.
Heating devices are mounted in place and leveled. Otherwise, air will accumulate in them.
After the installation has taken place, pipes are connected to the heat exchanger, going, naturally, to the lower and upper neighbors.
A jumper is installed to block the area when a leak occurs.
The riser starts.

When the neighbors have forbidden them to perform any joining work, then the pipes should be cut with a similar calculation so that the remaining part can be threaded (at least 6 turns) and a transition coupling can be installed.

If your neighbors have a metal riser and they allow you to connect to them, then it’s better to cut right here, it’s easier to get through the ceiling.

If your neighbor has a riser made of plastic pipes, in this case you also need to select plastic pipes of the same diameter and connect to the neighbor through a specialized coupling. If you are planning a metal riser, then a piece of threaded pipe will need to be made, fixing the position of the riser in the neighbor’s apartment. In another case, you can turn its riser and you will need to do repairs on it too.

Scheme for replacing risers in an apartment or house

Replacing a cast-iron riser with one made of plastic in a private house differs technically from similar work in an apartment only for those who, in the first option, eliminate the possibility of obtaining a bunch of approvals and permits. Thanks to this, we consider this issue using the example of work in an apartment.

The work should be done according to the scheme described below:

Submit an application for deactivation to the Criminal Code;
Receive technical specifications indicating the technical parameters of those elements of the new riser that you have the right to use, as well as the permitted wiring diagram;
Buy consumables, taking into account the above requirements;
Approve the timing of work (start and completion of shutdown).
Turn off;
Do the work (the tenant can replace the heating riser in the apartment with his own hands or involve third parties);
Provide representatives of the management company with the opportunity to check the quality of work performed;
Start the heating system.
