What determines the comfort of home? Undoubtedly, from many factors. However, in any case, heat will be one of the paramount. It “enlivens” any building, and this applies both to a small-sized apartment in an old building, and to a luxurious house of several floors.
General information
Heat is provided through a heating system. Modern realities are such that it should be not only effective, but also very economical. At the same time, achieving such a balance is not very simple. In principle, if you seriously take on this task, then its implementation will not be difficult. To preserve heat in the home, it is necessary to correctly draw up a connection diagram for heating radiators. It can be implemented in different ways. Next, we consider the main ways to connect heating radiators.
Some features
The connection schemes for heating radiators are different. The choice of one or the other is carried out individually. This takes into account the efficiency of heat transfer and the method of wiring pipes. It is worth noting that the decision on the choice is made in accordance with all the features of a particular case.
Important point
To understand the connection diagram of heating radiators, it is necessary to clearly understand where exactly they are integrated. In this case, it does not even matter that all work will be performed by a master from a specialized company. Owners must know which system is being implemented in their home.
Simple option
The connection diagram for the "one-pipe" heating radiators is used, as a rule, in a multi-story 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, adjusting the heat supply is not possible. Accordingly, heat transfer depends on the design norm, which is inherent in the project.
More complicated solution
When considering how to connect a heating radiator, you need to pay attention to this option. Let's consider it in more detail. The operation is carried out as follows: hot heat carrier is supplied through one pipe, while chilled water in the opposite direction - through another. In this case, a parallel connection of devices occurs. The uniform heating of all batteries is an 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 a main regulatory document SNiP 3.05.01-85. It defines the basic requirements for a particular heating radiator connection scheme. The rules given in the document must be observed without fail.
Determining the installation location
The purpose of heating systems is not only space heating. The fact is that batteries provide some protection against the cold. Thanks to them, he can not enter the room from the outside. That is why the batteries are located under the windowsills. Radiators are specially placed in places where the heat loss is greatest. This refers to the area of window openings. Thus, an effective thermal 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 methods of connecting a heating radiator, it is necessary to draw up a plan for the location of these devices. Determining the correct installation distance is very important. Thus, their maximum heat transfer will be ensured.
The method of circulation of the coolant
In most cases, it is water that “travels” through the heating system. It can circulate both naturally and forcibly. In the latter case, the use of a special water pump is implied. He will push water throughout the system. This element is part of the overall heating design. 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 where power outages occur constantly. The pump is not provided in the scheme. In this case, the heating boiler is non-volatile. The movement of water through the system occurs due to the fact that the cold coolant is displaced by the heated fluid. The implementation of connecting radiators with such features depends on many factors. In any case, the following should be considered:
- The length of the heating main.
- Features of its passage.
Connection to the highway is carried out by means of branch pipes. All batteries are equipped with these elements (cast iron, aluminum heating radiators). The connection scheme is selected taking into account design features. The remaining openings must be closed. For this, air vent valves or special plugs are used.
Installation Features
Proper self-made installation in the future will not cause problems with the heating system. In this case, all requirements that are prescribed for the performance of such work must be observed. Ensuring tightness of all connections is also very important. It is worth noting that certain types of batteries must be handled with extreme care. In particular, this is relevant if a connection scheme for bimetal heating radiators is used. Their outer casing is very soft. He will easily remember in case of a blow.
The most common connection option
The 1-sided system for connecting radiators involves connecting the supply elements to the batteries on one side only. It is most convenient to operate in multi-storey buildings. In this case, a centralized heating system should function. In this situation, the batteries give out rated power. This is the main advantage of such a system. However, there is one caveat. If the radiator has more than fifteen sections, then the heat transfer will be reduced. Thus, this connection method is not suitable for particularly long batteries, and it is advisable to find another one.
Cross connect features
The heat supply pipe is connected to the upper part of the radiator on one side, and the discharge pipe - in the lower and in the opposite direction. This arrangement is great for long batteries that have a large number of extra sections. The coolant is distributed evenly throughout the radiator. Thus, the highest heat transfer coefficient is achieved. The diagonal pattern is characterized by losses of not more than 2%.
Scheme of the lower connection of radiators
In this case, the heating exhaust and supply elements are connected to specific pipes. They are located on opposite sides of the radiator from below. This option is inferior to those described above. First of all, this refers to the heat transfer efficiency - 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 applies to the construction of a house in accordance with an individual project.
Additional recommendations
Batteries may accumulate air. This leads to the formation of a kind of cork. This factor negatively affects the heat transfer of radiators. For this reason, it is desirable that they have air valves installed. This will make it possible to remove it from the batteries in a timely manner. It is recommended to install additional taps on both pipes. Thanks to this, if the need arises, 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. Then purge or replace. The temperature control valve is often installed on the supply pipe. At the same time, a locking element is mounted on the outlet, respectively. This is especially true in multi-storey buildings. Thus, it becomes possible to adjust the amount of coolant that enters the battery and control its power. Heat dissipation 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 at least 10 cm. Due to this, the air flow coming from it will turn into a barrier that will not allow cold to pass into the room.
