How to change the radiator: the choice of heaters, connections, piping elements, installation tips. We change the batteries with our own hands. Instructions for choosing heating radiators
Interested in how to change a heating radiator? This question requires a balanced approach, since even a minor mistake can lead to emergencies and financial damage from damage to property (neighborly or personal). This guide is intended to highlight the main aspects related to the installation of heating batteries. We hope that with its help you will be able to change heating radiators quickly, efficiently and inexpensively.
When it becomes necessary to change the heating radiator in the apartment
The question of replacing heating batteries does not arise every day, and, therefore, the average resident of our country does not have a wide range of knowledge in this problem. The need to change the heating radiator appears either during a major overhaul, or if there are obvious defects in the battery caused by improper installation, wear during operation, or low quality heating equipment. Possibly also mechanical failure radiator due to a sharp jump in pressure in the heating system, which is professional language called "water hammer".
Another reason to change the heating radiator may be due to contamination of the battery ducts due to salt deposits on the inner walls or contamination of the coolant. In this case, the battery loses its efficiency and cannot supply the room. comfortable temperature. For residents of many multi-storey buildings replacing the radiator with a model with a large number of sections is the only way to get the required temperature in your apartment.
In private low-rise buildings, replacing a heating radiator with a more modern model can improve the heating efficiency. In addition, manufacturers of heating equipment constantly offer the latest heat control devices that can only work with certain battery designs.
Even the most reliable equipment has its resource. Radiators are no exception. If you do not promptly change radiators that have already served the period specified by the manufacturer, then their failure can lead to serious consequences, especially in the cold season.
How to change a heating radiator through the housing office
AT high-rise buildings The heating system of one apartment is inextricably linked with the heating of the whole house. This means that unprofessional work on the installation / dismantling of radiators in one of the apartments can lead to improper operation of the house heating system. At the same time, residents can change the heating radiator through the housing office only if:
Batteries have expired;
The heating radiators are out of order.
In other cases, only maintenance and local repairs are performed. According to existing standards, the operating period for cast iron heating radiators is from 15 to 30 years (when operating in open systems) and from 30 to 40 years (in systems closed type). If your batteries have served longer than the specified period, you must contact the relevant housing office services with a request to change the heating equipment. And here it is worth noting that the replacement of heating radiators in apartment building is included in the category of overhaul, the timing of which the operating company may not know.
To replace heating radiators, you can submit an appropriately executed application to the Housing Office. Since the problematic communication with representatives of this organization is known to all, it is recommended to submit an application in 2 copies. In one application with a request to change heating radiators, the responsible employee of the housing office must make a note indicating the number and date of its registration. This copy remains with the applicant and will be useful in the course of further relationships with employees of the operating office.
When communicating with the ZhEK specialists, it is worth focusing on the fact that if the requirement to change the heating radiators is not met, then material damage as a result of an accident from a battery breakthrough will have to be compensated at the expense of this organization. The practical experience of many tenants shows that resolving this issue with representatives of the maintenance office is a rather troublesome and lengthy process. It is for this reason that many do not want to contact the managing organization. However, knowing your rights is a good start for the successful completion of such relationships.
When deciding to change heating radiators, you should choose the right type of future battery. This choice should be made taking into account the functionality of the device and its aesthetic characteristics. When choosing a heating radiator, pay attention to the following parameters:
For every 2 m 2 there should be one section of the heating battery, and an additional section should be provided for the entire area.
According to the regulations, for heating residential premises brick building needed thermal power at 34 watts. For panel houses and new buildings, these figures are 41 and 20 W, respectively.
The decision to change heating radiators should be made in without fail and be coordinated with the responsible persons of the Housing Office. The heating system parameters are calculated individually for each facility, taking into account the number of radiators, the capacity of the coolant and the power of the equipment. If the radiators are changed without appropriate coordination, then it is possible to significantly reduce quality parameters heating.
How to get permission to change the heating radiator yourself
If it is impossible to change heating radiators through the operating office, then in order to obtain permission to carry out work independently, it is necessary to provide the following documentation:
Statement;
Registration certificate for housing and documents confirming the right to own an apartment;
Thermal calculation of installed radiators;
Certificates that confirm the possibility of installing all the necessary elements for connecting heating radiators (faucets, pipes, batteries, fittings, valves, etc.).
The application review process can take up to 60 days. Before you change the heating radiators, you also need to apply for turning off the riser with the drain of the coolant. After installing new batteries, an application is submitted for technical expertise of the connection.
How to change the heating radiator in the apartment with your own hands
Step 1. Choose a heating radiator
Before you change the heating radiator correctly, it is useful to get up-to-date information on the various types of such equipment. Experts distinguish:
Panel batteries. Their design consists of two or three panels along which the coolant moves. Such radiators are produced from rolled steel and are equipped with a side or bottom connection. Devices are different high speed heating.
Column batteries are a structure of two collectors connected by tubular columns. Aluminum alloys can be used for their production (along with steel).
Section type radiators include two sections (or more), where the coolant moves. The number of sections is limited only by the maximum allowable weight of the battery. Given the range of models on the market, you can change the heating radiators to bimetallic batteries sectional type, as well as on steel, cast iron and aluminum structures.
Regardless of whether you turn to specialists or decide to change heating radiators yourself, you need to buy batteries excellent quality. The main criteria for the selection of heating radiators:
Strength. In addition to cost and performance, radiators must be reliable. This parameter can be determined by the value of the allowable working pressure, which is indicated in the accompanying documentation. In order to change heating radiators to reliable batteries, you need to choose new equipment with predominantly durable in case of emergency pressure surges in the system. As useful information the following data can be given: when the coolant is supplied to the 9th floor, a pressure of 6 atmospheres is created, and if it is necessary to supply the coolant above the 22nd floor, then the pressure is already over 15 atmospheres. Such values are not acceptable for aluminum products used in low-rise buildings. The maximum allowable pressure for cast iron radiators is 9 atmospheres, so they can be used to heat apartments in houses with no more than 9 floors. In high-rise buildings, it is permissible to change heating radiators only for bimetallic equipment or for batteries made of high-quality steel grades. Working and test pressure can be found in the product data sheet.
Corrosion resistance. Corrosion resistance is one of the main selection criteria for heating batteries. Leaders in this category are cast-iron heating radiators. Aluminum products are considered the worst in this indicator. If you still decide to change the heating radiators to aluminum equipment, then it is advised to add anti-corrosion additives to the coolant.
Heat dissipation. Since the main purpose of radiators is heat transfer, batteries should be selected based on their power. This indicator is also prescribed in the product passport (for some models, the heat transfer power of one section may be indicated). The calculation of the power indicator is made taking into account the standard according to which for heating square meter required (depending on the height of the ceilings and wall thickness) power from 80 to 120 watts.
The most pressing moment, for which radiators are installed, is an indicator of their heat transfer to heat the room. The accompanying documents for the battery indicate its power (or the power of one section may be indicated). To calculate this value, it should be remembered that 80-120 W of coolant power is required per 1 m 2 of a traditional room (this depends on the height and thermal insulation of the walls).
Features of heating batteries from different materials:
Aluminum radiators. Due to their low weight, it is possible to change such radiators without high-strength fasteners. Aluminum structures stand out for their thermal conductivity, aesthetics and design.
Steel radiators. This type of battery is the most popular for arranging heating systems in apartments. Such radiators are distinguished by anti-corrosion resistance, and you can change them without any problems.
Cast iron radiators characterized by the most affordable cost and high durability. To ensure the necessary degree of thermal conductivity, cast iron radiators are supplied with a large number of sections.
Bimetal radiators - latest version heating equipment. They are light weight and stylish design. Changing bimetallic radiators is easy even with your own hands.
Step 2. We prepare the place and select the tools
The best way to change heating radiators is to negotiate with the neighbors of the lower and upper floors about a complete replacement heating pipes. The best option is to get consent to the tie-in new pipe from the exit from the radiator from the top floor to the entrance to the radiator installed at the neighbor below. Such a solution will allow you to quickly change the battery in your apartment without cutting the pipes and will allow the neighbors to get a new pipe section at your expense.
If the neighbors refuse to cooperate, in order to change the heating radiator, you will have to cut the old metal pipe from the floor to the ceiling and make a reinforced polypropylene pipe insert. When connecting radiators, polypropylene or metal-plastic products are used, as well as metal pipes, welded on the slopes. The most popular solution is the use of metal-plastic products, which are easy to install and have a longer service life.
Before changing the heating radiator, it is necessary to block the flow of water into the system. After that, the maximum possible volume of water should be pumped out and the system should be shut off already near the battery. It should be noted that during the dismantling process, water will flow out of the radiator, so it would be nice to prepare containers of the appropriate volume in advance.
When the battery is removed, proceed to do the following:
Measure and fix the parameters of the pipe outlet from the radiators installed at the neighbors from the upper and lower floors;
Calculate the parameters of the pipe required to connect a neighbor from the top floor, taking into account the width of the ceiling between floors;
Measure the distance to the neighbor's battery from the lower floor (taking into account interfloor overlap);
Measure the length of the pipe that will run in your apartment;
When choosing pipes, it is necessary to choose a product with a diameter corresponding to the pipe that was used when connecting the old radiator.
Another point that you should not forget, if necessary, to change the heating radiator, is the equipment. For each battery you need to buy:
4 plugs (1 blind and 2 through passages of the appropriate diameter, as well as a plug for the Mayevsky tap, which will help remove air from it when the system is started);
A set of gaskets for each of the selected plugs;
Reinforced pipes made of polypropylene;
Shut-off valves "American", necessary for shutting off the heating radiator in order to carry out its maintenance or change it to a new one;
Polypropylene tap for switching on heating system with closed taps "American", which ensures the circulation of the coolant even with the battery removed;
PPR end fitting with a diameter of 20 mm for connection with neighbors' radiators.
You can change the heating radiator yourself if you have the appropriate set of tools, which includes:
-
Marking pencil;
Soldering iron for soldering pipes;
Keys: gas and adjustable;
Drill and drill, which can be used to arrange the technological holes necessary for attaching the radiator to the wall;
Bulgarian with a disk for metal;
For situations where you need to change a heating radiator with a tie-in into existing pipes, you will also need a lerk for external threads.
Step 3. We dismantle the old radiator
In most cases, old batteries are connected to pipes using spurs (devices with a long thread on which a coupling with a lock nut is screwed). Such a connection serves as an effective solution, if necessary, to change the heating radiator. To dismantle the old battery, it is necessary to act according to the following algorithm:
Twist the locknut to the end of the threaded connection in the places of the lower and upper battery connections.
Using a level and a plumb line, determine the cutting point. The place must be chosen so that at least 10 mm of thread remains.
Use a level to precise cut in the horizontal plane. If the pipes are cut crooked, changing the heating radiator will become a problem.
Cut the pipes according to the established marks and remove the radiator from the fasteners. After dismantling the battery, the old brackets are removed from the wall.
If the new radiator is different in size from the one you need to change, you should cut the pipes to the desired length and thread on their edges. If the heating system is old enough, then it is better to use welding to connect the pipes, since they can be deformed along the seam when threaded.
To lengthen the pipes, special inserts or ecoplastic are used.
Threaded connections for installation are prepared by trimming the edges with a grinder. To eliminate burrs, it is advisable to twist the locknut.
Step 4. Apply markings and install the radiator
The heating radiator is fixed at the designated points, taking into account the following features:
The lower edge of the battery should be located at a height of 100-150 mm from the floor. If you change the heating radiator with a lower placement, this will worsen the air flow and create difficulties during cleaning.
To ensure normal convection, the heating battery is supposed to be at least 150 mm from the window sill.
Excessively pressed radiator to the wall reduces the efficiency of heat transfer. Adjustment of the distance to the wall is carried out by screwing in the mounting brackets. With the correct placement of the radiator, the distance to the wall should be between 30 and 40 mm.
To change the heating radiator, during installation, it is necessary to follow the sequence of actions:
AT winter time before changing the heating radiator, you need to agree with the housing office to turn off the riser. As a rule, the performance of such work in winter is allowed only in exceptional cases (an emergency condition of the radiator or a critically low temperature in the room where the children are).
After turning off the riser, open the drain cock. After that, you can change the heating radiator. Futor nuts must be screwed onto the new battery, and underwater pipes must be equipped with ball valves.
When installing ball valves, a threaded connection is applied sealing material. Tow demonstrates the greatest efficiency in matters of ensuring the density of threaded connections. It is wound on a thread coated with any kind of paint (except for water-based paint). Tow is wound clockwise from the edge of the threaded connection. After that, a layer of paint is applied over the tow.
The tap is screwed in such a way that there is no thread left on the pipe. The protruding tow should be covered with paint, after which the connection will be as reliable as possible after drying.
At the connection points of the heating battery, there are two internal threads, into which the futorki are screwed. On one side of the radiator, nuts with a left-hand thread are installed, and on the other, with a right-hand thread. practical solution will be the use of through nuts, thanks to which it is possible to mount the battery in different positions. Futor nuts are fastened using seals made of rubber or paronite.
At the points of connection of the radiator to the system, you need to install the mating parts of American women. After that, a plug is installed at the lower entrance of the radiator, and a Mayevsky crane is fixed at the top.
After the assembly described above, the radiator rises, and the tap is connected to the American. This moment will prevent the radiator from falling during subsequent work. A cardboard sheet can be placed under the bottom edge of the battery.
The heating radiator is fixed to the wall using special brackets. For correct installation these fasteners using a level, you need to mark the wall. In the marked places, holes are made for installing hooks.
After fixing the 4 fixing hooks, it is necessary to tighten the connecting nuts with an adjustable wrench.
How much does it cost to change the heating radiators in the apartment
Advertising of the services of specialists who will help change the heating radiator is easy to find on the Internet. The ads, as a rule, indicate the cost from 800 to 5000 rubles. With such a range of prices, it is rather difficult to understand where only the cost of installation is indicated, and where - the entire complex of works. In a proposal to change heating radiators in an apartment, the cost may be indicated without dismantling the old battery, without preparing brackets or without connecting equipment to the system. It turns out that all hard work will have to do it yourself. The customer is more interested in the total cost of all operations, i.е. how much does it cost to change a heating radiator on a turnkey basis. The standard set of works includes the dismantling of the old radiator and the installation of new equipment without any modifications to the connection pipes. In this case, the master does not cut new threads or transfer the radiator attachment points.
Before changing the heating radiator, it is worth calculating the full cost of the procedure. The first item here is the price of a new battery. Since the market offers the widest choice of radiators at different prices, it is rather difficult to take this moment into account in our example. After the replacement battery is purchased, it is necessary to close the riser and drain the coolant from the system. These works are carried out exclusively by representatives of the Housing Office or another management company. The estimated cost of the procedure is approximately 500 rubles, but it can completely change based on the "human factor" and the regional location of your home.
Further financial expenses are associated with the acquisition of materials. To change a heating radiator with installation on polypropylene pipes, you need to buy:
2 taps with American D ¾";
3 mounting brackets;
Corners 45°;
4 coupling adapters;
2 tees;
2 meters of polypropylene pipe.
The approximate cost of the entire set is about 1800 rubles. For this amount, you can buy everything you need to change the heating radiator. But note that this is the minimum configuration.
The following costs are associated with the work of the wizard. On average, for a service to change a heating radiator in an apartment, the price on the market starts from 2,500 rubles. This amount includes only the work itself. It is important to remember that this figure is subject to fluctuation in different regions. To get an estimated estimate, add up all the above costs:
Master's work - 2500;
Materials - 1800;
Shutdown of the riser - 500.
Total: 4800 rubles. Of course, in each individual case, the cost of changing a heating radiator can differ markedly, but the overall estimate, one way or another, consists of the components indicated here.
If you want to change heating radiators using metal-plastic pipes, then the estimated cost will increase due to more expensive couplings and adapters.
The mounting kit remains unchanged and includes:
2 taps American Ø ¾";
Mayevsky kit for connecting the battery (a set of fittings);
3 mounting brackets;
2 tees Ø 20/16/20;
2 connections Ø ¾" male thread / 20;
2 connections Ø ¾" female thread / 20;
2 meters of pipe Ø20.
In this version, a set of materials will require about 2300 rubles, and the total amount will increase to 5300. In some areas, the price of this kit is much more expensive.
The question arises: is it possible to change the heating radiator in a more economical way? At budget option installation of the battery is made without taps and jumpers. In this case, it will be possible to regulate the temperature in the room exclusively with the help of ventilation. To inexpensively change the heating radiator, you will need:
Mayevsky kit for connecting the battery (a set of fittings);
3 mounting brackets;
2 connections Ø ¾" male thread / 25;
2 connection Ø ¾" female thread / 25;
Pipe Ø25 - 2 meters.
Such a kit costs about 800 rubles, and it is possible to change the heating radiator for 3800 conventional units.
What to do if you changed the heating radiators, but they do not heat
The most common battery replacement error is incorrect connection. When the coolant is supplied to the radiator from below, then hot water does not heat up the entire structure. To solve this problem, it is not necessary to change the radiator. It is enough to use a special duct extension. If in a sectional battery heat comes only from the first, so-called segments, experienced craftsmen help make correct calculations and improve the whole system. One of the factors to consider for efficient space heating is the number of units. For a gravitational system, their number does not exceed 12, and for a circulation system, structures with a number of nodes from 20 to 24 are selected. An increase in the number of sections will reduce the efficiency of heat transfer.
Another thing that will affect the uniformity of heating the radiator is the diameter of the connection pipes. At small sizes, the pressure decreases, which worsens the heating process of the system. To eliminate this difficulty, you need to change the pipe to a product of a larger cross section.
To increase the heat transfer of the heating battery, placing foil or other reflective material on the wall under the radiator or painting it in more dark tones. It is important to keep the heating system clean. A modern solution to improve the quality of radiators is the installation of thermostats. At the same time, in agreement with the employees of the management company, the absence of a bypass pipe is allowed.
Often cases with a deterioration in the quality of the temperature regime in the room are associated with past repairs. Here you need to analyze the changes that have occurred and clarify their impact on the operation of the heating system. If during installation drywall partitions and boxes that cover communications, touching the radiator and drywall is allowed, for sure, heat transfer will be disturbed. In this case, part of the heat goes into the gap between the main wall and drywall sheet. If the battery was not too hot even before the repair, then after structural changes it will cease to heat normally at all, since part of the heat will be spent on heating an extraneous structure. To eliminate such an obstacle, you will have to redo the partition, and after that - analyze the efficiency of the battery.
How to change a section on a heating radiator
To dismantle several sections of batteries, it is not necessary to disconnect each separately. The ability to remove the required number of sections is determined by the size of the radiator key handle. With detailed description Radiator installation procedures can be found by watching the video:

Over time, poorly heating and unpresentable convectors must be replaced with new radiators that have a high heat transfer. But often apartment owners do not know which type of heating appliances to prefer, which pipes are needed to supply the coolant, and which shutoff valves to install.
Initial information
When you need to replace the heating system in the apartment, you need to collect all the information that may affect the choice. The operating pressure in the central heating system does not exceed 5 kgf/cm². According to the provisions of SNiP, the nominal temperature of the coolant cannot be more than 95 degrees, even under the condition of severe frosts. In fact, these norms are carried out by public utilities extremely rarely.In practice, in the case when there are many complaints from consumers about the cold in the apartments and for the period of dismantling the nozzle located in the heating system, the coolant is supplied directly from the main heating main, in which the temperature even reaches 140 degrees Celsius in extreme cold. The possibility of water hammer should also be taken into account - from the quick opening of the valve on the house when heating is started, the pressure at the front of the water flow can reach 25 atmospheres.
A similar effect also arises from an incorrectly mounted screw valve. When the coolant moves from the valve in the direction of the seat, the valve that is not fully open or torn off from the stem will periodically block the water flow, as a result of which a series of water hammers will occur in the riser.
At heating convectors, mounted by welding, the center distance at the eyeliner differs from the standard parameters for radiators (500 millimeters). Therefore, eyeliner requires partial replacement. If the heating is being altered in the apartment, it is advisable to get by with a set of tools available to each owner.
Replacing radiators
Before replacing the heating system in the apartment, radiators are purchased, bimetallic batteries are considered the best among them today. Why? The fact is that the basis of devices intended for heating housing are collectors and vertically arranged channels made of steel grades resistant to corrosion processes that are in contact with the coolant (more: ""). Experts warn: you should not give preference to cheaper bimetallic radiators - they only have steel cores on vertical channels. Such products are similar in strength to aluminum batteries.As for bimetallic radiators, their outer shell made of cast aluminum has developed fins. The combination of metals allows the production of heating appliances with a high degree heat dissipation and excellent durability. As an example of use the latest technologies in heating systems, Rifar Monolith bimetallic radiators can be noted, their appearance can be seen in the photo. For this series operating pressure is - 100 atmospheres, products withstand a test load of 150 atmospheres. The magnitude of the pressure of destruction is 210. See also: "".
- worker temperature regime- 135 degrees;
- heat transfer of one section - 196 watts;
- The warranty period provided by the manufacturer is 25 years.
To calculate the number of sections, a simple calculation is used: to heat every 2 "squares" of the area, one section must be installed.
But, if one of the apartment owners wants to have more exact result, then use the following data:
- thermal power per cubic meter of room volume - 40 watts;
- the presence of a window increases the need for heat consumption by 100 watts, and the door leading to the street - by 200 watts;
- if the room is corner or end, or the apartment is located on the outer floors, a coefficient of 1.2 - 1.3 is applied;
- depending on the region where the house is located, the heat output obtained in the calculations is multiplied by 0.7 - 0.9 (warm climate) or 1.2 - 2.0 (cold climate).
Calculation example. You need to find out how many sections with a heat output of 180 watts will need to be installed to heat a room measuring 4x5x2.7 meters, located on the first floor of a house in the Komi Republic (see also: "").
The calculation order is as follows:
- required thermal power - 4x5x2.7x40 \u003d 2160 watts;
- the presence of a window adds 100 watts - 2160 + 100 = 2260 watts;
- location on the first floor - 2260x1.3 = 2938 watts;
- with a regional coefficient of 1.5, it turns out 2938x1.5 = 4407;
- since the heat transfer of the section is 180 watts (4407: 180 = 24.48), 25 sections are needed, which can be divided into several batteries.
Pipe replacement
A new connection to heating radiators must be made of a material that is durable and not subject to corrosive processes. It could be a galvanized pipe, but an exact fit is required, and installation is laborious.Corrugated stainless pipe- an excellent solution to the problem, so that the replacement of the heating system in the apartment is not so difficult. At the same time, it is not inferior in strength to galvanized products, it bends at any angle. Fittings for it have a simple design of a nut and high-temperature silicone seals. Another positive point is that only a few adjustable or gas wrenches are required to install corrugated stainless steel. True, when connecting it with old risers, it is necessary to cut the thread (in more detail: ""). You will need a 3/4 inch die or die.
Unfortunately, the cost of such a pipe is not available to all consumers. For example, a meter of a 20 mm South Korean TM Kofulso pipe costs about 200 rubles. European similar products will cost 2-3 times more.
Replacing shutoff valves
Before you change the heating in the apartment, you need to purchase shut-off valves for each radiator.Would need:
- thermostatic head (you can throttle). With its help, after calibration, you can set the desired air temperature in the room, which will be automatically maintained (read also: "");
- shut-off valve. Allows you to completely turn off the heater.
- installation of throttling fittings requires the battery to be equipped with a jumper. Otherwise, the thermostat will regulate the entire riser from top to bottom, which is unlikely to please the neighbors;
- valves, when the heating system in the apartment is being replaced, it is advisable to choose modern ball valves, since they do not flow through the stem.
Features of installation work
When the materials are purchased, you can begin to replace the heating.The order of work in this case is as follows:
Resetting heating risers
In buildings with bottom filling, they are dumped in pairs. Which riser is connected to the one that needs to be replaced can be found out from the neighbors living in the apartment on the top floor, since the jumper is usually located with them (read also: ""). When looking for risers in the basement, experts advise you to navigate relative to the entrances. After finding the right flight of stairs, it is necessary to imagine the location of the room in relation to the entrance and the presence of pipes in it. After that, both risers are blocked, the plugs are unscrewed or the vents are opened.
In buildings with a bottom spill, the problem of how to turn off the heating in an apartment or room is easier to solve. In them, the risers are dropped one at a time, but you will need to close 2 valves - the one in the attic and in the basement.
Dismantling the convector
The old heater is dismantled in the following sequence:- using an impeller or a hacksaw above the bend directed to the convector, an incision is made on the vertical section of the riser;waiting for the suspended water to flow out of the riser;
- the pipe is cut at the incision site and under the lower outlet to the battery. The convectors are usually attached using a mounting gun, so you need to cut off the dowel heads and remove the heater.
Thread cutting
A die holder is put on the pipe, and with a long side - it will provide the die with a strictly perpendicular position relative to the axis of the riser. Before cutting the thread, it is necessary to clean the paint and provide for the die to enter by chamfering with a grinder, a file, or pressing the edge of the pipe with a gas wrench.
To make the die go easier and not leave scoring, the pipe prepared for threading should be lubricated with any oil. To enter the die, it is pressed against the end of the riser, applying maximum effort, and then the holder is rotated. After cutting the beginning of the first thread, the riser is fixed with a gas wrench so as to compensate for the torque from the die. Otherwise, you can damage the connection of the piping and the radiator in the apartments below and above. It is enough to make a thread with a maximum of 5 threads, since it is only needed for mounting the adapter fitting on corrugated pipe.
Installation of radiators
To avoid heat loss, you need to know how to change the heating in the apartment correctly.Installation of radiators is carried out in this way:
- the device is hung strictly according to the level, while depending on the type of brackets, one or another method of fastening is used. In the absence of brackets, the wall is drilled to a depth of 8-10 cm using a 9.5 mm drill and a dozen reinforcement is driven into the hole. When the radiator is installed, the fittings are cut in place and bent up;
- for bimetallic radiators, the standard cross section of the plugs is 25 millimeters, so the thermostat and valve are screwed using adapters. In order to ensure the sealing of the connection, linen with a sealant or paint is used. The thermostat head is mounted horizontally so that warm air from the piping does not pass through it;
- from below and from above on the riser and on the valve with a thermostat, an adapter is mounted on the pipe;
- in order to connect the corrugated pipe to the fitting, it is inserted into the hole and the nut is clamped with an adjustable wrench, at the same time the silicone sealant reliably compresses the ribbed surface. The eyeliner is also carried out according to the level, but it should not be located strictly horizontally, since a minimum slope is required to prevent the radiator.
Starting the heating riser
When starting the risers, you need to wrap the plugs on the winding and fill them with coolant.In this case, one should not forget about such nuances:
- when screw valves are mounted on the riser, it is necessary that water comes from the spill in accordance with the arrow on the body, otherwise the valve may tear off;
- first you need to equalize the pressure in the riser and bottling by slightly opening one of the valves and waiting until the noise of the water subsides. Then it is necessary to open completely this and another valve.
When replacing the radiator during the heating season, to resume circulation, the main thing is not to forget to bleed the air in the battery on the top floor.
For reference: refusal of heating in the apartment and turning off the heating system for other residents in the house can result in undesirable consequences.
In the context of a total struggle for savings, increasing the efficiency of the heating system is one of the priority tasks. To solve it, it is necessary, first of all, to replace the old batteries with new modern heating devices. How to do it yourself is described in this article.
In order for the house to always be warm, it is necessary that all heating appliances worked with maximum efficiency. In many houses, to this day, there are obsolete registers with low efficiency. In fact, heating residential premises with such batteries is throwing money away. Significantly improve indoor comfort and at the same time reduce heating bills by replacing old batteries with new ones.
First you need to talk about the types of modern batteries. Conventionally, they can be divided into three classes:
- Steel, battery with steel case. In order to increase the heat transfer area, and, consequently, the efficiency of such batteries, one has to do very a large number of internal partitions. As a result - a rather high cost - a two-kilowatt battery will cost about 3,500 rubles.
- Aluminum. They have thicker walls compared to steel ones and, accordingly, more high efficiency. They are subject to the damaging effects of alkali, which is added to the water flowing in heating networks so that scale does not form on the inner walls of the heat pipes. cheap material and ease of manufacture provide a low price - about 2000 rubles. per battery with a power of approximately 2 kW.
- Bimetallic. Steel interior, aluminum exterior. They combine the advantages of previous types of batteries and do not have their disadvantages. The average price is about 2600 rubles. for two kilowatts.
Thus, when installing a battery on a central water supply system, it is necessary to use either steel or bimetallic radiators - aluminum ones will quickly collapse under the action of alkali. When installing an autonomous heating system, for example, in private homes, it is advisable to use aluminum radiators in order to save money.
So let's get started. Let's replace the old registers with a modern battery.
Required tools and materials
To carry out the work you will need the following tools:
1. Angle grinder (grinder with a disc for metal).
2. A set of keys.
3. Perforator with a drill with a diameter of 12 mm.
4. Soldering iron for polypropylene pipes with a diameter of 25 mm and scissors for cutting.
5. Building level, tape measure, pencil.
Materials:
1. Polypropylene pipe with a diameter of 25 mm, reinforced with fiberglass.
2. Fittings and accessories for polypropylene pipes.
3. Battery connection kit.
You can buy all these elements separately, then you will need:
- radiator cap 1"x½": left - 2 pcs., right - 2 pcs.;
- plug ½", drain valve - Mayevsky tap;
- angle valve ½ for supply and return lines;
- fixing the battery to the wall.
4. The battery itself.
Battery Replacement
1. The most difficult stage of any work is the dismantling of the old system. We drain the water. We make two deep cuts on the pipe at a distance of about 15-20 cm and, using a gas wrench, carefully break out the pipe section. It is not worth cutting the pipe completely, as internal stress the disc may jam in the pipe, resulting in tool breakage and injury.
2. We remove old pipes as much as possible. In our case, to the plug of the adjacent radiator along the water supply branch, and the outlet corner along the return line.
3. We wind the winding on the transition fittings and screw them into the supply and return lines.
4. We mark the place where the battery is attached using a level and a tape measure.
5. We drill holes in the right places, insert the dowels and screw in the radiator hooks.
6. We begin to tie the battery. First, we screw in the plugs - two with a right-hand thread, two with a left-hand one. Since there is on traffic jams sealing ring, then you do not need to use the winding.
7. In upper part We screw the tap with an American into the supply. To do this, use the handle of the gas key and the protrusions on inside Americans. Let's not forget about winding.
With this tap, the temperature of the battery is adjusted. We open the tap. To do this, twist it to the side with the + sign.
8. In the lower part of the battery, opposite to the return, we screw the plug.
8. On the other hand, we screw the valve to the return line and open it with a hexagon.
9. Screw the drain valve into the remaining unused top battery plug. Since it has an O-ring, no additional winding is needed.
10. We hang the battery in place. We mount the supply and return lines from polypropylene pipes. Observing the sequence of soldering the pipe, solder the battery to the line.
When installing pipes made of polypropylene, it is necessary to provide for compensation gaps for the expansion of the pipe when heated. Pipes should not be cemented when they pass through ceilings and walls.
11. It remains to fill the system with coolant and bleed air using the Mayevsky tap.

Who should change the heating batteries in the apartment?
The apartment was bought in 2007. For a long time no one lived in it, and when I moved in, it became clear that the apartment was poorly heated. As the locksmith explained to me, it is necessary to replace the heat distributors (those that were owned in the apartment during the transfer) with batteries, which I have to buy from them and put them in for money too. Are there benefits for single moms? Do I have to pay for this? What kind of examination should I do to prove that the temperatures are below the required level?. Many neighbors are just as cold. What is the reason that the apartments are cold? Did you make a mistake with ? This year we completed the renovation of the facade of our house, the walls were greased, but the apartments are not warm enough. How to act correctly? Collect signatures from neighbors?

There can be many reasons. From a legal point of view, we can advise the following: You must replace the batteries at your own expense, as well as purchase them. Perhaps your MO provides for appropriate benefits. Since the problem is common to the whole house, it is much easier to solve it “with the whole world”. The procedure for filing a claim to the management company: But in any case, the first step is to measure the temperature in the premises of the apartment. According to the standards, the temperature in the rooms should not be lower than +18 C, and in the corner rooms - not lower than +20 C. The thermometer must be placed at a distance of 1 meter from outer wall and 1.5 meters from the floor. The measurement is performed within 10 minutes. Preferably keep a schedule internal temperature by the hour. If the thermometer reading is below the standard temperature, then you should contact the control room of your management company. Tell the specialist your details and the reason for the appeal. The dispatcher is obliged to inform you of his data and the data of the registered application (number and time), as well as the reason for the lack of heating in your apartment, if it is known. If the reason is unknown, then the dispatcher is obliged to agree with you the exact time and date of the heat check in your apartment. Based on the results of the verification, an act is drawn up, which is signed by both parties. If you do not agree with the drafted act, then a new time and date of the inspection are determined, to which a representative of the state housing inspectorate is already invited. Based on the results of the re-inspection, an act is drawn up again. If the temperature in the apartment is below normal, you have the right to demand a recalculation of housing. To do this, you must have the following documents on hand: 1) Application act. Makes it up Management Company after your call to the dispatcher within a day. Employees of the Criminal Code must check everything on the spot and draw up a protocol in triplicate. One is provided to you, the second - to the heat supply organization and the third - will remain with the public utilities. 2) Inspection report - it is drawn up after the problem is fixed, and it must necessarily indicate the number of full days and hours during which there was no heat. The recalculation takes into account the size of the living space, the number of registered persons, and even how many degrees the air temperature in the apartment was below normal. The amount received will be credited towards the payment of the accrued amount of the next month. If you were refused recalculation or do not react at all to your statements, go to court with a lawsuit about. Such claims are not subject to duty. Even if your communication with housing and communal services specialists did not lead to warming in the apartment, then by such actions you can at least save some of the funds for paying for heating services by redirecting them to pay for the electricity spent when using an electric heater.

Dear Olga. According to paragraph 6 of the Rules for the maintenance of common property in an apartment building, approved. Decree of the Government of the Russian Federation of August 13, 2006 N 491 with the composition of the common property includes an in-house heating system consisting of risers, heating elements, control and stop valves, collective (common house) heat meters, as well as other equipment located on these networks. And common property, as you and I know, should not be changed at our expense. However, from clause 1.4 of Table 2.3 to the METHODOLOGICAL RECOMMENDATIONS on the formation of the scope of work on overhaul apartment buildings as part of the implementation of July 21, 2007 No. 185-FZ “On the Fund for Assistance to the Reform of the Housing and Public Utilities”, in-house heating devices disappeared from the common property of MKD.
1.4. Repair or replacement of the heating system:
1.4.1. Repair or replacement of distributing highways and risers.
1.4.2. Replacement of shut-off and control valves, including on a branch from risers to heating appliances in residential premises.
1.4.3. Regrouping or replacing heating appliances in common areas.
The contradiction is clear! However, the Foundation will not be guided by the NLA, which has greater legal force (clause 6 of the Rules), will not change the radiators in the apartment at its own expense. He will be guided methodological recommendations developed, approved and published by him. And this means that we will change the batteries (heating devices) at our own expense. At the same time, the Foundation will not be interested in whether there are devices that turn off the radiators or not. According to his MP, they are ours, which means we have the cards in our hands! And I'm not sure that the court will be on our side. Unfortunately, you did not specify the year of birth at home. This is to the fact that the service life of cast iron radiators is 25-30 years. This is not such a long time, considering that the only empty apartment was 8 years old. Therefore, the reason for the low temperature may be the unsuitability of radiators for heating purposes. But since the heating season has begun, you may not be allowed to change batteries if they do not have disconnecting devices. The reason for the low temperature may be the poor quality of the heating service (poor heating, in other words). According to clause 105 of the Rules for providing owners and users of premises in apartment buildings and residential buildings, approved by Decree of the Government of the Russian Federation of May 6, 2011 N 354 upon detection of a violation of quality public service the consumer notifies the emergency dispatch service of the contractor or another service specified by the contractor. The utility service provider is obliged to conduct an inspection, after which an act is drawn up. If the temperature is below +18C, then the cost of payment must be recalculated.
Unfortunately, all this in the laws sounds correct and beautiful, which in practice is given with great difficulty. You need to act collectively. Contact all authorities. To Rospotrebnadzor, to the prosecutor's office, to the city authorities. People turn to the Commissioner for Human Rights, in the media, and so on. Take action!
Good luck. My answer is your feedback.

Hello Olga!
The owner's burden is to be responsible for the upkeep of his property.
However, you could have been provided with services of inadequate quality, so it makes sense to first file a complaint with Rospotrebnadzor in order to establish the degree warm water, as well as its quality, because it is possible that the radiators are simply clogged with rust and other dirt due to the quality of the common pipes and the quality of the water flowing through them.
Rospotrebnadzor will conduct an examination without your funds.
Sincerely, Law Firm "YOUR GARANT".
We are waiting for feedback. Thank you.

Batteries, if there are no taps that turn them off, are common property.
Therefore, none of the owners of the apartment buys or installs them.
The responsibility lies with the company servicing the MKD.
Only in single-family houses, the batteries themselves are changed by the owners of the house at their own expense.
If it is cold, you need to call a representative of the service company to draw up an act on the temperature in the apartment.
Valuykin Roman Nikolaevich(10/19/2015 at 08:15:23)
Olga, good afternoon!
On the basis of clause 1 of part 1 of article 36 of the LCD "the owners of premises in an apartment building own the common property in an apartment building on the basis of the right of common property: premises in the house that are not parts of apartments and are intended for maintenance more than one room in the same house, including inter-apartment landings, stairs, elevators, elevator and other shafts, corridors, technical floors, attics, basements in which there are engineering communications, other equipment serving more than one room in this house (technical basements).
As follows from paragraph 1 of Article 290 of the Civil Code Russian Federation"the owners of apartments in an apartment building belong on the basis of the right of common shared ownership common areas houses, supporting structures of the house, mechanical, electrical, sanitary and other equipment outside or inside the apartment, serving more than one apartment".
In paragraph 6 of the Rules for the maintenance of common property in an apartment building, approved by Decree of the Government of the Russian Federation of August 13, 2006 N 491, it is said that heating elements (radiators) are classified as common property, despite the fact that they heat only one dwelling and are not intended by themselves to serve more than one dwelling.
Based on part 3 of article 162 of the LCD "in the contract for managing an apartment building, composition of common property apartment building which will be managed
, and the address of such a house.
In this regard, the owners have the right, in agreement with the managing organization, to establish in the annex to the apartment building management agreement a list of common property objects, the responsibility for the proper condition of which lies with the managing organization. Good afternoon, Olga! The obligation to pay the cost of replacing batteries rests with either the owner of the premises or the management company, which bears these costs at the expense of funds collected from the owners of the premises under the line "maintenance and Maintenance housing "Justification: Decree of the Government of the Russian Federation No. 491). If there are valves on the heat supply system in your apartment that shut off the heat supply to the room, then everything that goes beyond this valve is YOUR property and you change it at your own expense. If there are no valves, then the management company will bear the costs, because it will be common house property.
If you think that the builders are to blame, you can first contact Rospotrebnadzor and the Prosecutor's Office, and then demand that the guilty person reimburse the costs incurred by you in connection with the replacement of batteries).
Good luck! I would be grateful for your feedback)
The procedure for replacing heating through the UK and ZhEK.
With the beginning of the heating season, all general house issues fade into the background, because. there is a need to put in order the heating system of the apartment. Many residents have no idea that the procedure for replacing heaters is quite laborious and time consuming. The legislation allows owners, in addition to the Criminal Code and the ZhEK, to apply to third-party organizations to carry out such work. But still, without the knowledge of these companies, it is impossible to replace the batteries.
In our article, we will talk about the procedure for replacing the heating system in an apartment through the Criminal Code and by contacting third-party specialized organizations.
Stages of approval for work on the replacement of heating radiators in the apartment
First of all, you need to know that all units connected to the common house heating system are included in the common house property. This is spelled out in Decree of the Government of the Russian Federation No. 491, paragraph 6 of August 13, 2006 “On approval of the Rules for the maintenance of common property in an apartment building ...”. So, according to the law, the replacement of any components in the heating system must be agreed with the Criminal Code, since this is connected with the general heating system, which is intended for each residential building separately. It contains all the heat supply data - installed power, size of the coolant, its temperature and the number of connected heating units.
Make the right calculation, plus take into account all the side factors (independent changes in the thermal insulation of apartments, installation plastic windows etc.) is not possible without the involvement of professionals, and if we do not forget that when replacing batteries, the owners want to increase the number of sections of each of the radiators or mount more powerful heating units as if “in reserve”, then an increase in total heat loss is inevitable . In this case, with a single-pipe heating option on the floors above, from which the distribution of the coolant through the riser begins, it will be extremely hot in the apartments, and the residents will freeze on the lower floors, and vice versa - with the lower acceleration of the line, it will be hot on the lower floors, and it will be cold on the top floors. It turns out that, at their own request, residents cannot change batteries in their apartments, because. There are rules that must be followed by everyone.
Owners who replaced batteries in their apartments without coordinating the issue with the Housing Office or the Criminal Code can legally be obliged to return the heating system to its former form at their personal expense - to install units of rated capacity. Therefore, any manipulations with radiators must be consistent with the Criminal Code.
For example, when the replacement has already been made, and you plan to legalize it, you should contact the expert commission, which, in turn, if there are no violations of design indicators, can confirm the legality of installing radiators. Compliance examination heating units primary project and the admissibility of their installation in the apartment without prejudice to common system of the entire house is paid by the owner of the apartment in which he wants to replace the batteries, because. it is he who comes up with the initiative to change the heating system of the whole house.
When replacing the batteries in your apartment is not a major or planned renovation of your home, the process of finding professionals to replace the batteries in your apartment will most likely fall on your shoulders. such work is not within the competence of the Criminal Code. But if you have no idea where to turn to for the problem of replacing heating units in your house, you can come to your management company and explain to them the essence of the issue. They must redirect you to necessary organization engaged in similar work, and their (UK) representatives will carry out a planned shutdown of the water supply, and carry out control and verification activities with already installed devices. In some cases, the UK may take over this work.
But in the vast majority of cases, applicants prefer to contact third-party organizations, because. Tenants’ relations with the management company are usually not the warmest, plus, the cost for which the replacement will be made by third-party firms will be an order of magnitude, or even two, less than the price that will be requested from the management company. Moreover, today there are many similar institutions on the market that can quickly and efficiently do the job.
After the organization is found, you should make sure that it has an SRO license to provide this type of service. This is the first thing you should do as the absence of such a license will nullify all attempts to obtain permission from the Criminal Code for the work. If everything is in order, you should contact the Criminal Code with a package of documents. By the way, the set of documents is no different from the one that you would provide if the replacement would be carried out personally by the Criminal Code, with the exception of confirmation of the company's admission to the production of such work.
In addition to the application for replacement, the Criminal Code provides:
Certificate of the presence of the organization you have chosen in the unified database of the Unified State Register of Legal Entities;
Title documents for the apartment;
Technical documentation of the premises where the batteries will be replaced. It may take about 1.5-2 months for the management committee to review the entire package of documents.
To refuse the admission of the contractor to the production of works, the Criminal Code does not have the right. Pay attention to the term for consideration of the application for a replacement. In the event that the work will be carried out by the management company, this period will be somewhat longer.
If everything is in order with the documents, the owner should return to the Criminal Code and submit another application, but this time about turning off the riser and draining the coolant from the common house heating system. After obtaining a permit, which specifies the exact time and duration of the shutdown, the organization performing the work is notified about this. In the event that the work will be carried out by the Criminal Code, such an application should not be submitted. Now the management company must notify the tenant about the time the riser is turned off.
After completion of the work, employees of the management company are invited to conduct a special technical expertise. Further, in the absence of claims from the UK, a document is drawn up on the registration of installed heating units.
We examined this option in detail, because. it is the most acceptable for residents in many respects. If you decide to work through the Criminal Code or ZhEK, then first you need to establish the reason for replacing the batteries, because. fortunately, we don't have to pay for everything. Plus, work through the Criminal Code may be delayed indefinitely, tk. there are no provisions in the legislation regulating the time frame in such cases.
The owner can perform all of the above actions in a short time, but it will most likely take a long time to wait for a specialist from the management company and the development of a work plan (you are not alone with us; shortage of personnel, etc.). In general, eternal truths.
The only plus here is that if the replacement is done through the Criminal Code or ZhEK, then you can be sure that the new heating devices will be approved and registered.
Who pays for the stages of work on replacing heating radiators in an apartment?
Today in our country there is a document called "MDK 2-04.2004" Methodological guide for the maintenance and repair housing stock"(Approved by order of the Gosstroy of the Russian Federation of 2004)".
The specified Manual clearly states who and in what cases should pay for certain types of work. As for the replacement of heating units, there are two options: if you decide to replace old (operating) radiators with more modern ones, then this, in accordance with the Manual, is regarded as unscheduled work, which means that the consumer will have to pay for the production of such. The same applies to situations from the category "bad heat", etc. Management companies are obliged to closely monitor the heat supply of the house, which in turn must comply with established standards. Everything else, within limits, is at the expense of the tenant. And there's nothing you can do about it.
As for the replacement of emergency or failed radiators, plus the elimination of all kinds of leaks and other things, this is the direct responsibility of the Criminal Code. Such work must be done free of charge. That is why, in the case of contacting the Criminal Code, you need to clearly know the reason for the replacement. Very often, the Criminal Code evades responsibility, saying that this case is not part of their responsibilities. Or they rush to draw up an estimate for paid work. In this case, the owner may file a complaint with the Housing Inspectorate. The complaint should indicate that the responsible persons refuse to fulfill their direct duties. Measures will be taken as soon as possible.
