Independent heating in the apartment: comfort and minimum
Residents of city houses know firsthand about such “charms” of central heating, such as cold batteries, the late inclusion of heating networks, sudden accidents and large utility bills. Therefore, few of them do not dream of their own heating. There is nothing impossible in it. You only need to get permission for independent heating in the apartment, and the rest of the work will be helped by the instructions below.

Preparation of documents
If you decide to design autonomous heating of an apartment with your own hands, then before you start work, you must obtain permission from the relevant government agencies.

To do this, you must prepare the following documents:
- A standardized statement of your desire to re-equip your own privately owned apartment to use an autonomous heating system.
- Technical passport of the premises with indication of all utilities laid in the apartment (water supply, heating, sewage and electricity).
- Documents confirming your status as the owner of the apartment to be converted.
- Technical project of the modernization of the dwelling for the use of individual heating network.
- Written statements of all persons who live in the apartment, that they agree to re-equip the premises to use their own climate system.
Note! This is a general package of documents that you will need in any case. But if you use a gas boiler as a heating device, you must also obtain a permit from the organization that supplies gas and controls the use of gas equipment.

All of these documents are sent to the management company, which makes the decision on issuing a permit or refusal. Without a positive response to your statement, there is no point in moving on to further events.
After receiving a positive response, the subsequent process of registration of documents is as follows:
- Based on the letter, you need to obtain technical specifications that will be the initial data for the preparation of the heating project.. In addition, technical conditions are required for contacting the gas service, which grants permission for the installation of gas equipment.
- The statutory period for the issuance of TU - 10 days. You may be denied this. Remember that the legal basis is only the absence of a gas pipeline in the house or the inability to supply bottled gas. All other reasons are illegitimate.
- Next, you should decide on the model of the heating boiler, take its technical characteristics and contact them with the design organization that will carry out the engineering project.
- This document must be approved by the organization that provides heating services.. There may also refuse. If you do not agree with the decision, you can go to court. As a rule, the judiciary takes the side of the claimant, since the requirements are completely legitimate.
- Based on the permission of the above-mentioned organization, a new project is being made - to disconnect the apartment from the centralized heating networks.. It can also be appealed.

And only after successful completion of all the bureaucratic procedures listed above can be taken directly for installation work.
Note! If you are going to install an electric boiler, it is not necessary to go through coordination in the gas service. This significantly reduces the time to obtain permission. However, you need to make sure that the wiring in the house can withstand the load exerted by your chosen equipment.
Calculation of power thermal device
An autonomous apartment heating system will work correctly only if the capacity of the selected heating boiler is sufficient to provide all rooms with thermal energy.
Correctly make calculations will help specialized engineering office. But the approximate value can be set independently. To do this, it is necessary to know the area of heated premises (S) and the amount of thermal energy spent on heating of 10 square meters (the so-called power density Wud).

Most often, the last value is assumed to be 1 kW.
But various external factors can affect it:
- climatic conditions of the area (in the northern latitudes, the value can double, in the south - decrease to 0.7 kW);
- wall material and the presence of a warming layer;
- ceiling height, number and area of windows;
- the floor where the apartment is located and the number of external walls in it (those that are in contact with the street, and not adjacent rooms).
A rough calculation is made according to the following formula:
Mto = S * wud / ten
Boiler selection
After obtaining the necessary permits and calculating the power, you can go to the store behind the boiler. There is a huge amount of various thermal equipment, which differs from each other not only in price, but also in other parameters.

The most important of them are listed in the table.
Parameter | Description |
Number of circuits | There are two-circuit and single-circuit models. The first ones allow not only to organize effective heating of the dwelling, but also provide residents with hot water. The latter are cheaper, however, if you need other benefits of civilization, you will have to spend money on the purchase of additional equipment. |
Fuel used | For the equipment of city apartments use gas and electric boilers. Other models of heaters should be installed in a separate specially equipped boiler room, which has a complex system for removing combustion products and a place to store fuel. In addition, you can buy a combined heater (gas-electricity). In this case, the climate network will remain operational in case of interruptions in the gas supply. |
Heat exchanger material | The most common steel heating boilers. They have compact dimensions, low weight and can be hung on the wall. Cast-iron units are more powerful, but they need to be mounted on the floor, because they will take more space in the kitchen. The devices of the latter type are more suitable for arranging climate networks in private homes. |
The design of the combustion chamber | There are boilers with open and closed (sealed) combustion chamber. The former are not very suitable for installation in apartments, since they burn the air in the room (that is, it is necessary to provide for powerful ventilation) and require a vertical chimney. The boilers with a sealed combustion chamber are equipped with a turbine and a special coaxial horizontal channel through which harmful substances are released and fresh air is drawn in, which is necessary for the combustion reaction. |

Let us consider in more detail the characteristics of gas and electric climate equipment.
Gas
The installation of gas-fired boilers is most common when equipping apartment heating systems. This situation is due to the low cost of this type of energy source, as well as ease of operation of the unit.
Therefore, we can safely buy the equipment:
- having two heating circuits;
- equipped with a steel heat exchanger;
- installed on the wall;
- having a closed combustion chamber.

The advantages of such a gas unit are as follows:
- It has a multi-level security system, excluding accidents and accidents. In case of gas supply shutdown, boiling or freezing of water, as well as other problems, the unit itself will stop working and will issue an appropriate error message.
- It can even be installed in a very small apartment, as it is hung on the wall and occupies a minimum of space.
- It works almost silently. A small vibration is accompanied only by the operation of the circulation pump, which is part of the boiler.
- It maintains performance even with significant pressure drops in the energy supply system.
- Has an affordable price.
Electric
The boiler, working on electricity, can act as a primary or secondary heating device. Such a unit as easy to install in the house, it does not require permission.

However, the electric boiler has one drawback - it consumes a large amount of electricity, the cost of which is much higher than the price of gas. In addition, not every wiring will withstand the power that is needed to ensure the operation of the equipment.
Nevertheless, the other advantages make the purchase of the device quite justified:
- The unit runs completely silently. The water heats up without a flame, so you will not hear the noise from the flashing and extinguishing burner.
- The device is completely safe for both the environment and humans. Even in the event of a breakdown, the residents will not be harmed.
- The electric boiler is so compact and aesthetically pleasing that it can organically fit into the interior of any room.
- A special controller allows you to set a comfortable microclimate in each heating circuit separately.
Independent installation of heating
The engineering network used for home heating is one of the most complex in design and engineering. In addition, an integral part of such a system is a gas or electric boiler, and they are devices of increased danger. Installing them yourself is not only not recommended, but also prohibited.
However, you can also mount other elements yourself.
These include:
- pipes supplying and removing water to the batteries;
- heating radiators, in which there is an exchange of thermal energy between the coolant and the air in the room.
Installing these parts will not cause you difficulties.

Tip! After installation, you need to perform pressure testing system. Such an operation will help identify defects and deficiencies in installation. To do this, you need to fill the system with coolant and run it in test mode, slightly raising the pressure above the norm.
If leaks are detected, the coolant is drained and problems are eliminated.
Conclusion
Despite all the difficulties that must be overcome to install an autonomous heating system, the result will not leave you disappointed. But besides heating, there are other engineering networks in the apartment that need to be modernized.
