Do -it -yourself heating system

The choice of heating system for a private house is a rather complicated and responsible process. A properly selected heating system is the key to the presence of constant heat and comfortable living conditions in the room. One of the most popular heating schemes is Leningrad. We learn about its features, methods of organization and advantages.

Hand heating system - Features and dignity of Leningradka

The heating system called Leningrad implies the use of one pipe for supplying a heat medium. At the same time, the system goes from one highway with a gradual arrangement of heating devices along which the heat medium circulates. Two pipe wiring options are distinguished:

• vertical;
• horizontal.

The pipe laying scheme must be determined even at the stage of building a house. It is recommended to use this heating scheme in a one -story or maximum of a two -story house.

According to the principle of operation of Leningrad, it differs in simplicity of execution. The heat carrier, in our case, the water, moves from the boiler to the feed line, which breds it throughout all rooms. After that, the heat carrier enters the boiler again. Thus, the system is integrity in the form of a closed contour, characterized by cyclicity.

In each room you should install radiators that are connected to the feed pipe. The quantity and size of radiators is determined in the ratio with the area of \u200b\u200bthe room and its size.

This system operates with the natural type of circulation of a thermal carrier or with a pump, which provides forced movement of water in the system. The presence of an additional pump provides high functionality in the operation of the equipment. In addition, shut -off valves and devices to control the temperature are installed along with the radiators. The absence of these devices negatively affects the effectiveness of the equipment.

Among the advantages of installing additional equipment to the Leningrad system, we select:

• the possibility of self -adjusting temperature;
• decrease or increase in temperature on various heating devices;
• If necessary, in the repair or disconnecting of a certain room from heating, it is enough to close special cranes.

Each heating system has both advantages and disadvantages. We offer to get acquainted with the advantages of Leningradka:

• excellent indicators of the efficiency of fuel consumption, in addition, it is possible to save material funds during installation work and during the operation of equipment;
• All materials for the installation of the system are easily accessible and acceptable in cost, there is a huge selection of pipes, radiators, boilers and locking valves;

• The ease of installation work and operation of the equipment, if necessary in repair, is enough to close the crane and remove the radiator to replace it or maintenance.

However, this system is also distinguished by certain shortcomings:

• Heat is distributed unevenly in rooms, especially when using natural circulation, therefore, in most cases, additional installation of the pump is required;
• With horizontal wiring of pipes, problems arise with the installation of warm floors;
• For greater efficiency of the system, the water itself, which is a heat carrier, should be increased.

Two -pipe heating system of a private house with your own hands

A single -pipe heating system allows you to circulate the heat carrier in a circle. A two -pipe system involves the use of two pipes going from batteries to the boiler. At the same time, two -pipe heating is more difficult for its construction and large expenses for the purchase of materials. For the circulation of the thermal carrier, two pipes are used, one of which supplies water, and the second is a return. The installation of each heating element implies the presence of a return and filing.

A two -pipe heating system allows you to distribute heat in all rooms of the building. However, on each heating device there should be an element in the form of an adjusting throttle. With it, it is possible to adjust the temperature in all parts of the system.

The two -pipe heating system is used both in private and in multi -storey buildings. In the second case, to adjust the distribution of heat, in the basement, which is the place of the roying, the pipes are installed much larger diameter than in the apartments.

The circulation of the heat carrier in a two -pipe heating system in the same way as in a single -pipe is compulsory or naturally. There are two methods of wiring pipes - upper and lower, it is they who determine whether the system needs additional pumping equipment.

Performing the upper wiring, the pipes are laid at a height, so in this case there is a constant pressure that the heat carrier supplies in the system. The appearance of such a system is quite aesthetic, the main pipe is located above the doorways. Additional costs are necessary for the installation of the tank of the expander that regulates the pressure in the system.

The lower system wiring is based on laying the pipeline in the lower part of the house under the windowsill. In this case, the expansion tank is installed directly in the room and does not need additional insulation. To create additional pressure in the room, a circulation pump is installed. Its installation is carried out on the return in order to avoid damage to the equipment with too hot the temperature of the heat carrier.

The installation site of the expander is determined by its type. A closed tank is installed anywhere in the house. Installation of an open expansion tank is carried out at a level exceeding the height of the direct segment of the pipe. If this is not done, then inside the system there are traffic jams from the air that needs to be removed.

If a two -pipe heating system is designed for a small house, it is advisable to choose pipes with a diameter of about 35 mm. In multi -storey buildings, pipes with a diameter of about 5 cm are mounted. To adjust the thermal return, choose radiators of which the size of which can heat the room in which they are installed.

There are three options for connecting radiators to the system:

• lateral;
• lower;
• diagonal type.

The installation of a private house heating system with your own hands is a rather complicated process, for which it is necessary to study all the subtleties of its implementation. In order to ensure good heat transfer between the heat carrier, the return pipe must enter the boiler from below. Therefore, most often, for the installation of a two -pipe heating system, options for boilers are selected that are installed on the floor.

The process of installing the heating system with the house with hands is quite complex, especially for buildings, the height of which is more than two floors. If there are no partitions in the multi -storey building between the floors, then as a result of heating, air from the first floor will move to the following. Thus, the air temperature on the second floor will be higher. In order to solve this problem, follow the following actions:

• For heating the second floor, use the dark floor, do not install radiators;
• Distribute the radiators in such a way that there is a third on the ground floor, and on the second there will be fewer heating elements.

Also, in the process of designing a house, it is recommended to equip rooms on the lower floor that do not need excessive heating, and the second should be the bedrooms, bathroom and children's rooms.

One -pipe heating system with a house with hands Scheme:

1. Perform the installation of the boiler, the power of which should easily heat all the rooms. When installing the boiler, strictly adhere to the technology for performing all work in relation to the type of equipment.

2. Install an expansion container, if it is open, it is recommended to mount it in the attic. A closed tank can be installed inside the room, but at its highest point. If the attic is unheated, it is recommended to equip the protection of the tank from thermal losses. If necessary, through the pipe, which is brought to the tank, the thermal carrier merges. The most convenient expansion containers of a membrane type, they are installed in any convenient place.

3. Next, perform the installation of a vertical riser, and then a straight pipe. The optimal value of the slope of the system is one percent. For a straight pipe, the slope is performed by movement to the boiler. At the junction of the devices for heating, the pipe is connected by tees.

4. Next, the installation of the reverse pipe is performed. Work begins with the installation of the pipe to the boiler. At the same time, the slope that is observed in the process of performing work remains the same. If necessary, the circulation pump is installed.

5. Next, the installation of radiators or a warm floor system is carried out. For these purposes, additional fittings are used.

6. The system is filled with water and air is removed from the radiators. Next, the boiler is launched, the taps are used to adjust heat supply. In the presence of drilling inside the pipes, unscrew the Maevsky cranes on the radiators to remove air.

One -pipe heating system of a private house with your own hands

A single -pipe heating system, which is also called Leningradka, was massively used in the process of building one -story houses in the Soviet Union. This idea was proposed in order to save money on laying communications.

This heating system is characterized by the absence of the presence of lighthouses of the return. Thus, it is possible to achieve a serious economic effect. However, a one-pipe heating system has many disadvantages, due to which it is not used at present. First of all, due to the fact that the radiators are connected in a sequential manner, it is not possible to control the intensity of their heating in different purposes of the premises. In addition, to carry out the repair of one of the batteries, it is necessary to disconnect the entire system from heating.

For the functioning of a single -pipe heating system, a serious pressure is required, which pushes water and circulates it. Therefore, this system needs mandatory installation of powerful pumping equipment.

The Leningrad system of one -story building needs a vertical spill. That is, the installation of an expansion container is necessarily performed in the attic.

In order to distribute heat evenly, batteries are installed with a large number of sections on the ground floor than on the second.

Among the main advantages of a one -pipe heating system, we note the savings of funds to ensure it. Therefore, this heating system is still mounted in private houses. In addition to saving materials, it is also possible to improve the aesthetic attractiveness of the premises, due to the lack of a large number of pipes and communications. Installation of thermostatic valves on radiators, installation of balancing valves and convenient ball valves can improve the process of operation of the system as a whole.

One -pipe heating system of a private house with your own hands

In the ratio with the installation scheme, a one -pipe heating system is divided into:

• vertical;
• horizontal.

Depending on the connection method, it happens:

• passing;
• Deadlock.

Depending on the method of transmission of the coolant:

• pumping;
• natural.

If the height of the building is more than thirty meters, then in any case pumping equipment is installed on the system. The system of heating of a private house with your own hands with a vertical type scheme involves heating water and lifting it on the riser. Further through the pipe of the distribution type, water falls into the radiators, performing their heating.

The thermal carrier in such a scheme circulates naturally, to achieve the efficiency of the heating system, pipes with a large section are used, and the highway is carried out under the slope. This scheme is independent of power supply, however, large pipes negatively affect the aesthetic properties of the room.

The second option is a horizontal scheme. It implies the installation of the highway inside the floor design. In this case, to reduce thermal losses, it is necessary to take care of additional pipes insulation. The supply pipe is also installed in compliance with the slope.

For the qualitative of the operation of any heating system, it is recommended to flush a private house heating system with your own hands. Thus, it is possible to improve the quality of thermal return, and increase the efficiency of the system as a whole.
