Connection diagrams of radiators. Ways to connect radiators

What does comfort in the house depend on? Undoubtedly, from many factors. However, in any case, one of the primary will be warm. It "revitalizes" any structure, and this applies both to a small apartment in an old building, and to a luxury house in several floors.

General information

Heat is provided by the heating system. Modern realities are such that it should be not only effective, but also very economical. At the same time to achieve such a balance is not very simple. In principle, if you take this task seriously, then its implementation will not be difficult. To maintain heat in the home, it is necessary to make a competent drawing of the connection scheme for the radiators. This can be implemented in different ways. Next, consider the main ways to connect the radiators.

Some features

Diagrams for connecting radiators are different. The choice of one or the other is carried out on an individual basis. This takes into account the efficiency of heat transfer and the method of pipe wiring. It is worth noting that the decision to choose is made in accordance with all the specifics of a particular case.

An Important Moment

In order to understand the connection diagram of the radiators, it is necessary to clearly understand exactly where they integrate. However, it does not matter even that all the work will be performed by a master from a specialized firm. Owners must necessarily know which system is implemented in their home.

A simple option

The scheme of connection of radiators of heating "one-pipe" is used, as a rule, in a multi-storey building. This option is considered the simplest. However, despite the availability of installation, this connection scheme for heating radiators has serious drawbacks. In some cases, the heat setting is not possible. Accordingly, the heat transfer depends on the design norm, which is incorporated in the project.

A more complex solution

Considering the ways to connect the radiator, you need to pay attention to this option. Let's consider it in more detail. The operation is carried out in the following way: the hot heat carrier is fed through one pipe, while the cooled water in the opposite direction is fed through the other. In this case, the parallel connection of devices occurs. Uniform heating of all batteries is the advantage of this system. There is also the possibility of regulating heat transfer. This is done using a valve, which is installed directly in front of the radiator.

Important information

There is the main normative document of SNiP 3.05.01-85. It defines the main requirements for a particular scheme for connecting radiators. The rules listed in the document must be observed without fail.

Determining the installation location

The purpose of heating systems is not only the heating of the room. The fact is that the batteries create a certain protection against the cold. Thanks to them, he can not enter the room from outside. That's why the batteries are located under the windowsills. Radiators are specially placed in places where heat loss is greatest. This refers to the area of window openings. Thus, an effective heat curtain is formed. Do not completely cover the battery with other similar heating elements. Otherwise, the density of the warm air flow will decrease. This will also affect the efficiency of heating the room. Before considering ways to connect the radiator, you need to make a plan for the location of these devices. Determining the correct installation distance is very important. Thus, their maximum heat transfer will be ensured.

Method of coolant circulation

In most cases, it is water that "travels" through the heating system. It can circulate both naturally and forcefully. In the latter case, the use of a special water pump is implied. He will push the water through the system. This element is part of a common heating system. The pump is usually installed near the heating boiler. It can also be provided with a structural element.

Scope of natural circulation

It is relevant wherever power outages occur all the time. A pump is not provided in the circuit. At the same time, the heating boiler is non-volatile. The movement of water through the system is due to the fact that the coolant is displaced by the heated liquid. The implementation of the connection of radiators for such features depends on many factors. In any case, the following should be considered:

1. Length of the heating main.
2. Features of its passage.

Connection to the pipeline is carried out by means of branch pipes. These elements are equipped with all batteries (cast iron, aluminum radiators). The connection scheme is selected taking into account the design features. The remaining holes must be closed. For this purpose, air vent valves or special plugs are used.

Features of the installation

Proper self-made installation in the future will not cause problems with the heating system. At the same time, all the requirements that are prescribed for the performance of such work must be met. Ensuring the integrity of all connections is also very important. It should be noted that with certain types of batteries you need to handle extremely carefully. In particular, this is relevant if the connection scheme of bimetallic radiators is used. Their outer shell is very soft. It will easily crumble in case of impact.

The most common connection option

The 1-sided radiator connection system involves connecting the supply elements to the batteries on one side only. It is most convenient to operate in high-rise buildings. At the same time, a centralized heating system must function. In this situation, the batteries produce a nominal power. This is the main advantage of such a system. However, there is one nuance. If there are more than fifteen sections in the radiator, the heat transfer will be reduced. Thus, this method of connection for extra long batteries will not work, and it is advisable to find another one.

Cross-connect Features

The pipe, supplying heat, is connected to the upper part of the radiator on one side, and the outflow - in the lower and opposite direction. This circuit is great for long batteries, which have a large number of additional sections. Heat carrier is distributed throughout the radiator evenly. Thus, the greatest heat transfer coefficient is ensured. The diagonal scheme is characterized by losses of no more than 2%.

Scheme of lower connection of radiators

In this case, the heating outlets and the supply elements are connected to the specific branch pipes. They are located on opposite sides of the radiator from below. This option is inferior to what was described above. First of all, this refers to the efficiency of heat transfer - about 10-15%. However, in some cases, this option is the most optimal. For example, when the heating system is hidden in the floor. In particular, this refers to the construction of a house in accordance with an individual project.

Additional recommendations

Batteries can accumulate air. This leads to the formation of a kind of cork. This factor negatively affects the heat transfer of the radiators. For this reason, it is desirable that air valves are installed on them. So it will be possible to remove it from the batteries in time. It is recommended to install additional cranes on both pipes. Due to this, if there is a need, it will be possible to do without turning off the heating throughout the riser and completely draining the water from the system. You just need to close the valve and remove the element. After this you can proceed with purging or replacing. The thermoregulation valve is often installed on the delivery pipe. At the same time, a locking element is mounted on the outlet, respectively. This is especially true in multi-storey buildings. Thus, it is possible to adjust the amount of coolant that enters the battery and regulate its power. Heat transfer of the radiator depends on several factors. In particular, this refers to the correct location of the battery. Ideally, if it is installed under the windowsill. The recommended distance is not less than 10 cm. Due to this, the air flow coming from it will turn into a barrier that will not let the cold into the room.
