Improving heat transfer is one of the main priorities in optimizing heating performance. The best way to improve system performance is to install new batteries. However, unlike a private house, to perform this work in the apartment you need to fulfill certain conditions. How to replace radiators and radiators in an apartment if their parameters do not meet modern requirements?
Problems replacing radiators and radiators
There are 2 situations when it is necessary to replace central heating batteries: a breakdown or the installation of new radiator models. In the first case, representatives of the Housing Department or the Special Economic Zone are called. Installation of a new system element is possible only if they confirm the impossibility of its restoration.
If the owner of the apartment decided to install new radiators himself, a number of coordination measures must be carried out. In no case should you do this without obtaining supporting documents from the management company (UK). Only with her consent and in the presence of representatives of the Criminal Code can the heating in the apartment be replaced. Otherwise, the following problems may occur:
- Changing the parameters of a common heating system. An increase or decrease in the volume of coolant in the radiator can lead to a decrease in the efficiency of work not only in one apartment, but in the whole house;
- To install a new battery, it is necessary to shut off the supply of hot water in the riser, which is allowed only to the staff of the Criminal Code. Unauthorized execution of this action may result in penalties;
- Before replacing a heating radiator in an apartment, you need to find out the temperature regime of the system. The calculated heat transfer of the battery depends on this, and as a result, its efficiency.
Activities to install a new heating device in the apartment begin with the registration of permits. Then it is necessary to purchase all the necessary components and, after agreeing on the installation date, to install new heating radiators. Each of these stages has a specific specificity and procedure. Therefore, it is necessary to consider in detail their practical implementation.
For current costing of the replacement of the heating radiator, you can analyze the proposals of commercial organizations.
Paperwork for radiator replacement
How to replace a heating radiator in an apartment building yourself? First you need to get permission from the UP. This may be a housing office, office of industrial development or homeowners association. It all depends on with whom the heat supply contract was drawn up. Specific data can be found in this document.
Having decided on the Criminal Code, you should write a free-form statement about the desire to replace the battery (or several) in the apartment. The following documents are attached to it:
- Documents confirming the right of ownership - purchase / sale agreement, gift certificate, etc .;
- Copy of passport or other identification document;
- A copy of the apartment plan with the radiators to be replaced.
Based on this documentation, the Criminal Code draws up a technical condition (TU) - the primary document giving permission for the replacement of heating radiators. The time for receiving the technical specifications can vary from a week to a month. It should spell out the requirements for a new heating battery:
- Thermal system operation;
- Pressure in central heating pipes;
- The rated power of the new battery and the volume of coolant in it;
- The method of connection to the pipeline.
Having received the technical specifications for the replacement of heating radiators, you can begin to choose a model. Most often, the choice is stopped on bimetallic or aluminum multi-section batteries. Also, do not forget about the connecting pipes. Often the replacement of the central heating battery is carried out along with the installation of a new pipeline.
To do this, you must first agree with the neighbors, since the entire heating network is considered common house property. That is why you need to get consent to disable the riser from all users. The corresponding document with signatures is provided by the Criminal Code.
After that, the Criminal Code provides a radiator passport, technical characteristics of the pipes (if they are also to be replaced), as well as the general battery connection diagram. Having received approval, you can agree on the date of work.
To reduce costs and labor, it is best to replace the heating in the apartment not during the heating period. In this case, overlapping the riser is not necessary. But all the same, all the above documentation is drawn up.
Total battery replacement cost
An important point is the correct calculation of the cost of replacing the heating radiator. It will provide an opportunity to plan costs in advance. It can also be used to optimize the financial budget of this event. In fact, this is a list of all costs with a detailed description of each of them. For self-replacement of a heating radiator, it is necessary to choose the optimal model. Its capacity must comply with the specifications from the management company. The best choice is the installation of aluminum or bimetallic radiators. The estimated cost of one section and characteristics can be taken from the table.
| Name | Radiator type | Power of the 1st section, W. | The cost of the 1st section, rub. |
| Bilit | Aluminum | 187 | 320 |
| Ferroli | Aluminum | 181 | 340 |
| Global | Aluminum | 140 | 430 |
| Raditall | Bimetallic | 148 | 340 |
| Bilit | Bimetallic | 196 | 430 |
In addition, you need to consider the cost of consumables. How can I replace a heating radiator in an apartment without pipes, valves and a Mayevsky tap? The selection of these components is best entrusted to specialists. As a result, based on the data obtained, it is possible to make a general calculation for the replacement of the heating radiator.
| Article | Qty | price, rub. | Amount, rub. |
| Radiator, bimetal. 6 sections | 6 | 340 | 2040 |
| Organization of eyeliner, bypass installation | 1 | 980 | 980 |
| Check valve | 1 | 480 | 480 |
| Ball valve | 2 | 415 | 830 |
| Mount kit | 1 | 340 | 340 |
| Mayevsky crane | 1 | 140 | 140 |
| Riser shutdown service (only during the heating season) | 1 | 1200 | 1200 |
| Service - radiator installation | 1 | 1400 | 1400 |
| Total | 7410 | ||
This is the maximum cost for replacing heating radiators in an apartment. If you carry out work in the summer and do the installation yourself, you can subtract the service for turning off the heating riser and installation. In this case, the total cost will be - 4810 rubles. This is significantly lower than the full, but at the same time, the owner of the apartment takes all the risks of adhering to the technology.
Obtained permission to replace heating batteries does not mean that work should be performed only by representatives of the Criminal Code. This can be done independently, or use the services of specialized companies.
Installing batteries and radiators
If you comply with the technical conditions for the replacement of heating radiators - you can perform their installation yourself. The technology is determined by the battery model, the parameters of its connection to the system.
There is a general scheme for replacing a central heating battery. To implement it, you will need the following tools and supplies:
- Universal gas key;
- Hammer drill;
- Construction level and tape measure;
- Winding kit for threaded connections. Unilock thread is best for this.
First you need to dismantle the old radiator.It may have a certain amount of coolant (depends on the method of connection to the heating system). At this stage, you must not damage the pipes. If the threaded connection is rusted (stuck) - it must be treated with WD-40. Having removed the battery, the integrity of the pipeline is checked. If necessary - replacement of the line or supply pipes is performed. For steel pipes, it is best to make a welded joint, since mechanical is more prone to gusts due to water hammer.
Before you make the replacement of heating in the apartment, you need to install the fixtures in the wall. In some cases, the old ones do not fit, so you need to mount a new kit. For this, a drill is used. After the final installation, check the correct location of the fasteners and their level.
When replacing a heating radiator in an apartment, it is first installed on the fixtures, and then connected to the pipes. At the end of the work, the tightness is checked and pressure testing is performed. It is necessary to control the quality of joints.
Is it possible to replace the radiator in the central heating system myself? This problem is solved, but it must be remembered that the first time the system is started, the pressure in the pipes can reach 4 atm. Therefore, special attention should be paid to the quality of materials and compounds.
