Replacing the heating in the apartment - features of the

Often the cause of cold batteries in the heating season is not the poor performance of the utilities, but the old heating system in the apartment. Accordingly, in this case, the replacement of pipes and radiators will help return the heat to the apartment. In this article we will try to gradually consider how this operation is performed.

Preparation of materials

The choice of radiators

Before replacing the heating in the apartment, it is necessary to purchase radiators in advance. Since there is a large selection of these devices on the market, the question of choice for many people is quite acute. Therefore, in the following we briefly review the features of the most common types of batteries:

From this we can conclude that for an apartment where installation of autonomous heating is not planned, bimetallic radiators are the best option.

Pipes for heating

After the choice of radiators is made, it is necessary to determine the pipes for heating. Most often for these purposes use the following options:

Note! Polypropylene pipes can be used only with perforated reinforcement. This is due to the fact that unreinforced polypropylene is subject to strong thermal expansion.

When choosing batteries, be aware that they differ in the way they are connected. The most common devices with side and bottom nozzles. The latter option is great for those cases when the heating pipes are in the floor.

If a battery with a large number of sections is used, then a diagonal connection should be preferred. In this case, the heat will be distributed evenly, respectively, the efficiency in this case is higher.

Heating replacement

The main nuances

Replacing the heating system in an apartment has a lot of nuances, since it is connected to a centralized system. The first problem that the apartment owner will have to face is draining the water from the system. To perform this operation, it is necessary to block the entire house, which can only be done by experts from the relevant state services.

Therefore, before proceeding with the replacement of radiators, you must contact the various departments. For disconnecting the batteries are responsible "teplovik" and housing maintenance offices. You should not try to replace the pipes without coordination with these services, as this could lead to serious fines being imposed.

Tip! Apply for permission to turn off the coolant as early as possible, as civil servants issue it after some time.

The main stages of the work

Replacing the heating system is not too complicated. Of course, it is desirable to have experience of similar work, and, for example, replacing the heater tap on the Cornfield, is not. However, if you adhere to the recommendations below, every home master can cope with this task.

So, the instruction for the implementation of this work is as follows:

• After the water from the system is discharged, you need to dismantle the old batteries and pipes. As a rule, the old pipes are made of steel, so for this work you need a grinder. It is necessary to be engaged in dismantle carefully, with observance of safety precautions.

• Next, you need to perform a fit and canopy of new radiators.. This stage is very important, as it is necessary to correctly align the vertical and horizontal to eliminate distortions. Therefore, work should be carried out using the building level. Before fixing the mounting elements, it is necessary to mark the wall. Installing the radiator "by eye" can complicate its connection to the riser, not to mention the external unattractiveness of such a decision.

• The next step is to assemble the installation kit for each radiator.. This includes the following elements - ball valves, Mayevsky cranes, radiator plugs, bypasses. All these elements are necessary for high-quality and efficient operation of the system.
• Next, the pipeline is installed, this process depends on the type of pipe material. For example, when using steel pipes, a threaded joint or welding may be used. Installation of polypropylene pipes is carried out by soldering using a special welding connection. On our portal you can learn in detail how to use this device. In the case when it is necessary to carry out the connection of plastic pipes to the steel riser, special fittings-adapters are used.

Tip! To fix the heating pipes on the wall, you can use special clips and clamps.

Here, in fact, all the main points of replacing heating in the apartment.

Battery Charts

Separately, it should be said about the ways of tying (connecting) batteries.

As a rule, the connection is carried out in the following ways:

• Installation of a radiator without jumpers - this option involves the installation of an American crane that allows you to easily dismantle the battery if necessary, for example, during repair.
• Installing batteries with a jumper - in this case, you can control the heating of the batteries by the valves and also completely block the radiator without interfering with the circulation of the coolant in the system.

Tip! To seal the threaded connections, use a fum tape.

The second option is more preferable, therefore experts at installation of modern systems use it.

System test

It should be noted that the installation of the system does not end the work, since it is still necessary to perform the test. To do this, you need to agree with the same people who blocked the coolant so that they let the water under pressure.

If there are any problems during the test, they should be fixed immediately. However, it must be borne in mind that in most cases full filling of the system is carried out only with a general start.

Note! Complete with radiators there is an instruction in which all the features of installation of heating devices of this model are indicated. Therefore, before installing the batteries, you must read the information from the manufacturer.

Installation of autonomous heating

Often, the replacement of heating in apartments is carried out with the transition to an autonomous system. In this case, the process can be more complicated, which is associated with a change in the heating scheme.

Therefore, before you install, you must prepare a heating project. In this case, you must specify the location of the heat source, as well as all other heating devices.

Unlike centralized, autonomous heating can be implemented in two ways:

• According to the one-pipe scheme;
• According to the two-pipe scheme.

Below we take a closer look at the features of each type of system.

Note! When planning autonomous heating, it is necessary to calculate the power of the heating equipment.

One pipe design

This option is the most simple and economical. Its meaning lies in the fact that all radiators are connected in series to one pipe. However, such a system has one major drawback - the last radiator in the circuit heats up less than the first.

This scheme is suitable for small one-bedroom apartments. The contour in this case around the room around the perimeter. Connecting radiators of the heating system is necessarily performed with a bypass, which allows you to adjust the degree of their heating.

According to the method of circulation of the coolant, this type of heating is of two types:

• Naturally - the circulation is carried out due to the difference in the density of hot and cold water. It uses a booster tank, which is located a few meters above the rest of the heating devices. In addition, the heating pipe passes under a constant slope.
• Forced - circulation is carried out using a circulation pump. In this case, the booster tank is not needed, however, an expansion tank is needed to compensate for the thermal expansion of the coolant.

A circulation pump or booster tank is installed immediately after the boiler, as shown in the diagram.

Two-pipe system

The meaning of this system is to use two pipes - for a hot coolant and separately for return. In this case, it requires almost twice as many pipes, which increases the cost of replacing heating.

In this case, the batteries can be connected in series or in parallel, and a circulating pump is always used.

The connection scheme in this case is as follows:

• A circulation pump and an expansion tank are installed between the boiler and the system.
• Next, the circuit is connected to the input of one or more batteries.
• From the first radiator in the circuit goes return, which is connected to the input of the boiler.

Here, perhaps, all the features of the installation of a two-pipe system. I must say that in the same way the replacement of heating in a private house is consistently carried out.

Conclusion

It is not difficult to replace the heating system in the apartment by yourself; you just need to draw up a wiring diagram and perform all the connections properly. In addition, attention should be paid to the choice of batteries and pipes, as this affects the durability and efficiency of heating.
