Scheme of connecting batteries in a private house. Ways to connect radiators. Lateral - the easiest option
Installation of heating in the house
The efficiency of the heating system is the main aspect that affects the comfort of living inside a private house. It is good if this system is connected to the central heating networks. If there are none, then it is necessary to organize heating system, which will have to be adjusted to those very comfortable living conditions. And one of the most important points in this case, it is a choice in a private house.
A non-specialist in this matter may doubt the correctness of the question posed. Indeed, many do not know at all that the connection scheme significantly affects the heat transfer of the heater, the movement of the coolant inside it and the intensity of the circulation of hot water. These are all the same factors that determine the degree of efficiency of the heating system as a whole.
First of all, you need to understand the piping layouts. Why is it so important? The fact is that saving materials is a common moment. Many residents of private houses at the stage of its construction or in the process of overhaul not always correctly calculate the cost of building a heating system. As a result, it is necessary to save on materials. True, there is an option where you do not need a large number of pipes, fittings and stop valves. But let's get it right.
Pipe layout
In private houses, two main wirings are used - one-pipe and two-pipe. What is the difference?
Single pipe
This is the most economical option where a small amount of materials is used. Essentially, it goes like this:
- From the heating boiler, a pipe is laid along the floor, which passes through all the rooms and returns back to the boiler.
- Radiators are installed on top of the pipe, and their connection is carried out through the lower nozzles. Wherein hot water from the pipe penetrates into the heater, filling it completely. Part of the coolant, which gave off heat, goes down and exits through the second pipe, falling back into the pipe.
It turns out a series connection of batteries with a lower connection of radiators. We note one negative factor that affects the efficiency of heat transfer. Serial connection in a one-pipe system is accompanied by a gradual decrease in the temperature of the coolant in each subsequent heating element. So it will always be colder in the last rooms.
How to solve this problem?
- You can connect a circulation pump to the system. It will allow you to evenly distribute hot water to all heating devices.
- Increase radiators in the last rooms, thereby increasing the area of heat transfer.
Two-pipe
Wiring diagram options
This heating scheme in a private house is the most efficient. True, the initial costs will be considerable. After all, you will have to carry out two pipe circuits - supply and return. But in any case, such a scheme has several advantages over a single-pipe one:
- The coolant is distributed evenly throughout all rooms.
- It is possible to control and regulate temperature regime in each room separately.
- Can be repaired on any heating element without shutting down the entire heating system.
- Reduced fuel consumption.
Wiring diagrams
So, we figured out the piping. We turn to the main issue - in a private house.
There are three main connection types:
- Lateral.
- Diagonal.
- Lower.
Lateral connection is one of the most common when it comes to the heating system in an apartment. City dwellers see it every day. In order to properly connect the radiator according to this scheme in a private house, it is necessary to bring the pipes along the wall from the side and connect them to two radiator pipes on one side - from below and from above. Most often, a pipe supplying coolant is connected to the upper pipe, and a return circuit is connected to the lower pipe. It is possible and vice versa, but in this case, the heat transfer efficiency of the device decreases by 7%.
Considered ideal. The connection scheme is as follows. The coolant supply is connected to the upper branch pipe, and the return pipe is connected to the lower one on the opposite side of the device. That is, inside the battery, hot water moves diagonally, hence the name of the circuit. The degree of its effectiveness depends on the uniformity of the distribution of water inside the device.
Lower heating medium connection
Radiators with a bottom connection are found not only in single-pipe piping schemes. In two-pipe they are also used, but only in low-rise private buildings. Let's face it - this is not the most efficient connection scheme. Experts say that with such a wiring, the heat transfer of heating radiators is reduced by 20-30%. Therefore, in this case, it is impossible to do without installing a circulation pump.
- First, the increase in the cost of all processes.
- Secondly, the emergence of dependence on electricity.
- Thirdly, additional payment for the electricity consumed during the operation of the pump. And although it consumes a little, it is still an expense.
And now the main question - which connection of radiators is better? When calculating the required power of heating devices, a large number of different coefficients are used - reducing and increasing. So, these coefficients are directly related to the connection being made:
- Radiators with side supply - K=1.0.
- With diagonal eyeliner - K = 1.1–1.2.
- With lower eyeliner - K = 0.7–0.9.
Now you yourself must decide which type of connection is best. But do not forget that piping often plays a fundamental role in the choice. This must be taken into account.
Conclusion on the topic
So, in the process it is necessary to take into account the scheme of their connection. We must pay tribute to the specialists who dismantled all the methods to the smallest detail. Simple inhabitants can only get acquainted with the information and apply it in practice. All options are quite simple, and you do not need to think about redoing something in your own way. Don't even experiment!
How to connect a heating radiator in a private house? This question is asked by many owners who are engaged in the arrangement of the heating system. There are several options for connecting radiators at once, they differ in complexity of execution, main characteristics, and possibilities of use.
Proper installation is a guarantee of the full operation of the system. Mistakes can lead to reduced efficiency and real power radiator.
There are several options heating systems, they differ in their design, depending on this, it is necessary to select the optimal connection scheme.

All modern appliances come with four open nozzles. This allows you to implement any scheme for connecting heating radiators, depending on your needs.
Important! It is necessary to take into account the fact that the wiring and directly the type of system can affect the connection. Depending on this, the optimal connection scheme is selected.
Main system options
To begin with, it is worth considering the types of heating systems. The most popular in our country are two main options:
- Single pipe systems.
- Two-pipe.
Basic radiator connection systems
The most common is considered single pipe system. It is used in high-rise buildings and in private buildings, it is as easy to install as possible. The coolant enters through the pipe from above, gradually spreading through the heating devices. But the system also has a number of features:
- You can not adjust the degree of heating of the radiators.
- Limited flow control capabilities.
- As an advantage - ease of creation and connection of devices.
For use in cottages and private homes, a two-pipe system is best suited. It provides a fast flow of water - a hot coolant is carried through one pipe, and an already cooled liquid is discharged through the other.
Important! Please note that when using a two-pipe system, you can only use parallel connection radiators. In this case, you can ensure their full operation.
Some features of a one-pipe and two-pipe system
Despite a number of disadvantages, a single-pipe system has many advantages:
- All elements are connected through a single circuit, the installation process is greatly facilitated, and additional costs are reduced.
- For small private houses, this is a fairly effective solution, most of its shortcomings appear only in high-rise buildings.
- This system allows you to use many options for connecting heating devices, it all depends on your wishes. By choice optimal scheme efficiency can be improved.
But when using one circuit, it is necessary to carry out an accurate hydraulic calculation in order to ensure the distribution of the coolant over all radiators. Any errors can lead to serious problems during operation and reduce efficiency.
It is impossible to install a large number of batteries on the branches, because the coolant cools down over time. Therefore, it is better to attach no more than 3 - 4 radiators. It is problematic to regulate the temperature, if a thermal head is installed in one of the devices, then in the future it will affect all other devices.
A two-pipe system solves a number of problems, but it will require some time for design and installation. You will have to spend a lot more materials, this fact increases the cost of the system. But it also has a number of advantages:
- You can use a gravity system or install forced circulation.
- Up to 10 batteries are installed on each branch, no hydraulic regulators are needed.
- When using two circuits, the supply and return of the return is carried out separately. You can put thermostatic valves, they will not affect other appliances.
- High flexibility. Radiator connection schemes are selected for buildings of any design.
Connection to a two-pipe heating system in a private house
As you understand, each option has certain advantages and disadvantages. Therefore, it is necessary to carefully choose a heat supply system, taking into account the number of devices and the main characteristics.
Scheme
Heating radiator connection schemes differ in their type and complexity. To begin with, it is worth listing the main options, considering their features and benefits, then you can make the right choice.
Basic connection schemes:
- Diagonal.
- Lower.
- Lateral.
How do these options differ from each other, and which method should you choose?
Diagonal type
How to connect heating radiators in a private house? It is believed that the greatest efficiency can be achieved when using a diagonal scheme. To do this, the inlet pipe will need to be connected to the upper branch pipe, the outlet pipe - to the lower one on the opposite side. In this case, the coolant will travel the maximum distance before it leaves the radiator. The efficiency is significantly increased, the device will be able to produce more heat.
Diagonal radiator connection
It is mandatory to use a diagonal connection for batteries with 10 or more sections. Only then it is possible to ensure its filling and use all the possibilities of a large radiator.
Diagonal connection is considered the standard, most manufacturers recommend using it for their devices.
Let's point out some of the disadvantages of this option:
- Communications cannot be hidden with boxes.
- A large amount of materials will be required.
- Complex wiring geometry.
- Serious inconvenience during installation.
This scheme can be used if the main parameter for you is the maximum heat transfer, and appearance and installation complexity are in the background. Usually, a diagonal connection is used precisely in private houses; it is practically not used in high-rise buildings.
Connection at the bottom
Such a connection is not the best option in terms of efficiency and performance. But when using it, you can disguise the battery in the room.
Connection at the bottom of the radiator
When applying this scheme, the efficiency is reduced by about 10 percent, but in private homes such losses are not very noticeable. For one-story buildings, it will be an excellent solution.
One of the drawbacks is that the upper part warms up much worse. Over time, it can become clogged, often there are accumulations of air. You will need to use Mayevsky cranes to solve this problem.
Lateral - the easiest option
Lateral radiator connection schemes are used especially often and have a number of advantages. They simplify the installation process and save materials. Achieved circulation over a large area of the battery and a sufficiently high efficiency.
Pipes are just installed simultaneously with gas boilers.
It depends on how the scheme for connecting heating batteries in a private house will then be arranged.
It is better to get acquainted with the current ones before making a choice in favor of certain devices. This will help to spend as little time and effort as possible on arranging a working system:
- Minimum 2 cm distance between the wall and the back walls on the panels.
- 8-10 centimeters should be equal to the gap, starting from the top of the radiator, and ending with the window sill.
- 10-12 centimeters - the minimum distance from the bottom of the battery to the floor.
In devices, heat transfer becomes less if these standards are not observed. Reduces the likelihood that the operation will be uninterrupted. And the very scheme for connecting heating batteries in a private house from a gas boiler ceases to be effective.
Radiators must have an adjustment function. It is automatic, either. Therefore, the kits are supplied with heat regulators. Thanks to which indoors it is easier to maintain the optimum level of temperature.
What is piping
When connecting, use two-pipe or one-pipe schemes.
Single pipe option
In addition, heating is not complete without such additional elements.
- Temperature controller. It helps to save fuel, maintain the temperature in the rooms at the same level.
- Air vents. Needed to release oxygen. It periodically accumulates in the pipes, because of which it becomes a destructive element.
- Stop valve. Maintenance with repair is easier for those systems that have a large number of cranes installed.
Expansion tanks are indispensable assistants in the construction of systems of any type. It is released in closed and open.
Paired with circulation pumps put only closed varieties. open tanks trying to place as high as possible. For example, in the house attic.
What about chimneys
And in this case, there are mandatory conditions. The outlet pipe at the boiler must exactly match the diameter. There are other subtleties:
- If the pipe approaches an unheated room, insulation is required in these places.
- It is unacceptable to have connections in places where pipes pass through roofs or walls.
- Three bends - the maximum number for the chimney from the boiler to the head.
Installation of heating batteries: main stages
The installation rules remain the same for each type of battery. It doesn't matter which one played the role of the main one, how the connections are made. The order of operations will always look like this.
- First, they shut off the entire heating system, drain the water.
- The battery is dismantled along with other elements of the old circuit.
- The use of dowels for marking and fixing brackets on the wall surface. A cement solution is needed for rubbing places with fasteners in order to level the surface.
- After that, the plugs begin to be installed. There are entrance holes for each pipe, on both sides. Plugs for the organization of the passage, on which the correct thread is applied, are wound in places where the connections are located. Linen strips with additional sealing adds tightness to the whole structure. At the top there is a valve mechanism that releases excess air.
- Radiators are hung on supports prepared in advance. Water special devices will help to check how correctly the levels are set.
- Mounting stopcock inside the passageways.
- Batteries are connected to the pipeline.
- The entire heating network is tested.
Do not get carried away with decorative protective screens. They look, but at the right time they can block access to thermostats. Because of this, the heating is turned off in case of insufficient heating.

The efficiency of the heating system depends on a number of factors, including the connection of batteries. After all, if the connection is incorrect, part of the radiator may remain cold even when high temperature coolant. Therefore, in this article we will consider how to properly connect heating batteries and in what cases, which schemes are advisable to use.
Connection Features
Ways to connect radiators
When installing heating systems in private homes, the following connection methods are used:
Unilateral | In this case, the supply pipe is connected from above, and the return pipe is connected from below to the same section. This heating battery connection scheme allows the radiator to heat up evenly. However, if the accordion has a large number of sections, then significant heat losses will occur, so it is better to use other connection options. |
Saddle and bottom | This method is an excellent option for cases where pipes run through the floor. The connection is made to the nozzles located at the bottom of the structure, in opposite sections. The disadvantage of this method is only low efficiency, since heat losses can reach 15 percent. |
Diagonal | It is used when connecting devices with a large number of sections. As you might guess, the inlet pipe in this case is connected from above, and the outlet pipe is connected from below, in the opposite section. This scheme for connecting heating batteries in a private house contributes to the uniform distribution of the coolant and maximum heat transfer from appliances. |
Note!
When parallel to the radiator, a bypass must be performed.
This will allow you to adjust the degree of heating of the device.
As we can see, the methods of connecting heating batteries depend on a number of factors, such as the method of laying pipes, the power of the equipment, etc. In particular, the type of system is of great importance. We will talk in more detail about the types of heating systems below.
System types
When installing heating systems, two schemes are used:
- Single-pipe - is the simplest, since the coolant circulates through one pipe, to which are connected in series heating appliances. Its disadvantage is that it does not allow you to regulate the heat supply. Therefore, heat transfer corresponds to the design norm laid down in the design.
This scheme is used in small systems, since with a large length of the pipeline and a large number of radiators, the devices will heat up unevenly. - Two-pipe - its meaning lies in the fact that hot water flows through one pipe, and the cooled water returns to the boiler through another. The connection of heating batteries in a private house in this case is carried out, respectively, in parallel. The advantage of such a device is the uniform heating of the sections, as well as the ability to adjust heat transfer.
Of the shortcomings, only the need for more pipes can be distinguished, respectively, the cost of the structure increases.
It should be noted that, regardless of the type of system, connecting heating batteries with your own hands can be implemented in two ways:
- vertically - heating device connects to a vertical riser, from which wiring is carried out to radiators.
- According to the horizontal scheme - the circulation of the coolant is carried out through horizontal pipelines.
The choice of the scheme for connecting heating batteries depends on the characteristics of the house. For example, if housing contains several floors, then the connection is implemented according to a vertical scheme.

Location selection
When deciding how to properly connect the heating battery, it is imperative to determine the location of the heating devices. The fact is that the function of radiators is not only to heat the premises, but also to create a thermal screen that prevents the penetration of cold into the room. It is for this reason that they are installed under window sills.
It follows that heating devices must be installed in places of greatest heat loss. Therefore, before deciding on the connection method, it is necessary to draw up a diagram with their location.
In addition, it is important to correctly determine the mounting distances, which will maximize the heat transfer of devices. So these distances should be as follows:
Note!
The window sill should not block or obscure the heater, as this will significantly reduce the efficiency of heat release.
However, in some cases, radiators can be covered with grilles.
Most often this is done when the heating devices do not fit into the interior of the room.
Mounting
The heating battery should be connected in the warm season, so as not to be left without heating in the winter. Therefore, it is necessary to purchase all the components in advance in order to carry out all the work quickly.
Note!
It is possible to purchase heating devices only after the heating scheme has been drawn up.
This will allow you to choose the correct location of the connecting pipes.
In addition, you must first calculate their power, you can find out how this is done on our portal.
It is necessary to start installation work after finishing the room.
The instruction looks like this:
- If old radiators are being replaced indoors, then first of all it is necessary to dismantle the elements of the previous design.
- Then it is necessary to determine the location of the structure and make appropriate marks on the wall. In this case, you need to use the building level so that the structure is installed evenly.
- Then you need to fix the brackets with your own hands using dowels.
- After that, the device should be installed on the brackets according to the instructions that are usually included with the radiators.
- After installation of the devices, it is necessary to connect them to the pipeline. This operation depends on the type of pipes. For example, if the pipeline, the connection of radiators is carried out using a special fastener - "American".
At this stage, the Ball Valves, as well as Mayevsky cranes. It should be noted that when using a heating battery with a bottom connection, it is not necessary to perform a bypass and install control valves. The latter is usually used in two-pipe systems with diagonal and lateral connection.
When installing shut-off valves, care must be taken to ensure easy access to them, even if the radiators themselves are closed.
- At the end of the work, you can fill the system with coolant and perform pressure testing.
Note!
When designing and installing heating, it is necessary to comply with the requirements contained in SNiP 3.05.01-85.
Here, in fact, are all the main features for connecting heating batteries.
Conclusion
In itself, connecting the radiators is not difficult. However, in order for the system to be effective, it is first necessary to correctly draw up its scheme. To do this, you need to take into account a number of factors, therefore, the preparation of the project should be carried out very carefully.
