Heating system of a private 2-storey building with your own hands. Schemes of heating a private 2-storey building

In the process of construction and long before laying the foundation, there are many questions related to heating. Each owner wants to achieve positive results, following the path of less resistance.

Scheme with natural circulation

Considering the scheme of heating a private 2-storey building, you can pay attention to a system that involves the natural circulation of water. The choice of the drawing will depend on the layout and area of the building. But this is the most widespread and customary for country houses and country houses. It differs little from the one used in the arrangement of heating systems in single-storey buildings.

When choosing such schemes of heating a private 2-storey building, you should remember the layout features that require the choice of a place for mounting the expansion tank. There is no need to place it in the attic, you can confine yourself to the second floor. There the tank can be anywhere. Of course, this should be the highest point of the room. The master must ensure that the water can be discharged. If you apply a similar method of connecting heaters, the liquid will come from above. Thanks to this, the heating of the radiators will be even, as for the heated premises.

In order to direct the movement of water, the pipes are located at a slight angle of 3-5 degrees. The diameter of the return pipeline should increase as it approaches the boiler equipment. If such heating schemes for a private 2-storey building are used, then the supply pipe can be placed under the usual window sills or ceiling.

Pluses of a heating scheme with natural circulation

It is important to consider the advantages of the scheme described above before starting the installation work. There are a lot of them. First of all I want to note the reliability of the design. In addition, among the positive aspects should be distinguished ease of operation, noiselessness of operation, independence from the supply of electricity.

Disadvantages of the scheme

If you decide to use the above-mentioned project of heating a 2-story private house, you should also remember about the shortcomings, which in this case are much more than pluses. First of all, it is worth highlighting the complexity of installation work and the need to lay pipes with a slope. Among other things, the heated area will be small. The system will not have enough pressure to heat the house if its area is more than 130 square meters.

You should also know about the low efficiency and significant temperature difference between the return flow and the feed. The latter circumstance negatively affects the operation of the boiler equipment. The internal surfaces of the system will be corroded, since oxygen will be present in the coolant. Owners of the house need to constantly monitor the state of evaporating water, which implies the need for its addition. As a result, scales can form on the pipes. Use antifreeze is unacceptable for the same reason. As another drawback, it is worth highlighting the significant material consumption of the system.

Types of circuits with forced circulation

Heating private 2- storey house with their own hands can be equipped and the principle of a system that operates through the forced circulation of water. According to the professionals, the following schemes are the simplest to install: one-pipe, two-pipe and collector. First, we will analyze the first variety.

Single-pipe heating system, made by myself

When using this scheme, the heat transfer medium will divide the heating devices into two branches. One of them goes to the first floor, while the other goes to the second floor. On each floor, a stop valve is installed at the inlet of the pipe. It will only heat half the rooms. After the pipes with the coolant pass through the heating devices, they will be combined into one system that will be suitable for the boiler equipment. To connect the batteries on each floor to be the same method, which is used in the conditions of single-story buildings.

Recommendations for the arrangement of the system

If you have chosen the above scheme of heating a 2-storey private house, the shut-off valve must be installed at the entrance of each heater. This is necessary to adjust the heating level of the radiator and balancing the system. At the output of the batteries, a shut-off valve is installed, which is used to cut off the radiator during repair and replacement. If you use such a connection scheme, you can change the heating devices without stopping the system and draining the water. To vent the air, a valve is installed on each battery at the top.

This scheme of heating a 2-storey private house involves the installation of batteries with a bypass line. This increases the uniformity of heating the building. You can also install heaters without bypass. In this case it is necessary to install in the house radiators of different thermal capacity, taking into account the loss of cooling water. This indicates that the farther from the boiler the battery is, the more sections it should have. If you neglect this rule, then in some rooms it will be hot, but in others it's cold.

Heating scheme without valves

When the heating system of a private 2-storey building is assembled by one's own hands, the shut-off valve may not be used. Rather, it can be used in smaller quantities. However, under such conditions maneuverability will be reduced. There is no need to speak about separate heating of the second and first floors in this case.

The main advantages and disadvantages of a single-pipe heating system

Using such schemes of heating a private 2-storey building, you ensure the ease of installation. Owners of housing at the same time receive effective heat transfer, as well as savings on materials. Among the drawbacks of the heating scheme, one can distinguish the uneven distribution of heat across the radiators and the need for balancing the system. However, all these drawbacks are completely devoid of a two-pipe system, which works by means of forced circulation of water.

Circuit with forced circulation

A two-pipe system with forced circulation guarantees an even distribution of heat. It is effective and sometimes compared to the circulatory system of man. In it to each radiator the coolant is fed through a branch running from the common supply pipe. The presence of a tap is also provided in the return pipe of each radiator.

Batteries are installed with air vent and shut-off valves on the feed. This allows you to change the heating level of the heater. In order to increase safety and eliminate excess pressure in the radiator, the tap-off valve is not installed at the outlet of the back-tube battery. Under the sill or ceiling, you can lay a feeding pipe. It is perfectly permissible to equip such heating of a private 2-storey building with their own hands. The diagrams presented in the article will allow you to carry out these works without recourse to specialists.

The main shortcoming of the two-pipe system is high material consumption. For the return and delivery of the pipe will need a double copy. Among other things, they are difficult to decorate, and hide is not always possible, which spoils the interior of the premises. All the above disadvantages are completely devoid of a collector circuit.

Description of the collector circuit

Such a system can be successfully used for a single-story or two-story house. It functions due to the forced movement of water, which is previously fed to the collector. Each heater must then be connected through a shut-off valve to the manifold. In the role of advantages it is worth highlighting the possibility of dismantling and installing radiators on the operating system, from which the coolant is to be drained and it will not have to be stopped.

The system is easy to manage. Each circuit is independent and connected to a separate automatic control system with its circulation pump. In a tandem with this heating system, you can use a warm floor. Pipes are laid in a raised floor, and also located in a separate cabinet. It can be easily installed such heating of a private 2-storey building with their own hands. Schemes, photos of similar drawings can be found in the article.

Recommendations for installing heating appliances in a two-story house

If you want to ensure an even distribution of heat in the home, it is important to correctly calculate the length of the highway, take into account the level of insulation of the house, as well as the presence of balcony blocks, window and door openings. The efficiency of heating will depend on the proper placement of heating equipment, this primarily applies to radiators. The battery should be placed under the window, and the warm air rising above it will block the cold masses from the window. Thus, you can eliminate cold air. When the heating system of a private 2-storey building is arranged by oneself, it is important to think about such premises as a boiler room, an entrance hall and a corridor. For them, one kilowatt of heat capacity per 10 square meters will suffice.

For the bathroom, kitchen and hall will need 1.2 kilowatt per 10 square meters. For a nursery and a bedroom, the level of thermal power should be increased to 1.5 kilowatts per same area. Thermal efficiency will depend on the floors, floor material and walls. In order to reduce costs, as well as to ensure the optimum heating mode in each room, you should use thermal regulators. The battery material will affect the system parameters. Today, aluminum batteries are the best option. High parameters are distinguished by bimetallic radiators, however, they will have to pay more for them.

If you know that the heating system is low enough water quality, then do not use aluminum radiators, which are most sensitive to aggressive conditions. Rigid or contaminated water will also affect the longevity of the equipment and the operability of the system. But steel and cast-iron batteries will last much longer. These factors do not have a negative impact on them.

Material of pipelines

The heating system of a 2-storey private house should be equipped using a quality pipeline. Modern technology almost does not use metal pipes, as corrosion processes are the cause of failure of such products. If you take into account that in smaller systems the pressure of the working fluid is used, it is better to use a plastic pipeline.
