How to connect a radiator: the nuances of the selection and installation of heating devices

Before you connect a heating radiator, it is advisable to familiarize yourself with the models of heating products, the rules of their installation, because only the choice of a suitable battery and its careful installation will be the key to high-quality system operation and a comfortable atmosphere in the room.

These batteries can be considered universal, as they perfectly “get along” with heating systems of any type. For servicing the premises of private houses, models with a maximum pressure of up to 6 atm are quite suitable. Products of reinforced construction that can withstand a pressure of about 16 atm are installed in high-rise buildings.



In the rooms, radiators are mounted under the window sill or are mounted side by side, on the wall. The eyeliner of pipes can be organized both on the one hand the heating device, and from the different. Moreover, in the case of a one-sided arrangement of pipes, it is not necessary to install multi-section models. With a versatile version of the supply pipe, you can mount the battery with the number of sections from 12 to 24.

To ensure good heat transfer, it is recommended to adhere to the following rules for placing radiators: from the floor - not less than 10-13 cm, from the wall to the product - not less than 2 -5 cm, to the window sill - not less than 10 cm.

When installing inlet / outlet valves, it will be possible to regulate the temperature in the room, turn off the radiator for repair or in emergency situations.

How to connect a bimetallic radiator?

These batteries combine the virtues of two metals - steel and aluminum - and are a worthy alternative to traditional cast iron batteries or oil coolers. Products consist of steel cores and aluminum housings. Thanks to the materials and design, heating devices withstand high pressure and have the best thermal conductivity.

When installing batteries follow a specific sequence of work:

  1. indicates the location of the radiator;
  2. brackets are installed;
  3. the battery is placed on hooks;
  4. pipes and a thermostatic valve are connected;
  5. An air valve is always installed to prevent gas accumulation inside the instrument.

Before starting the installation work, it is necessary to check the presence of all the components of the heating device.

In order not to destroy the tightness of the structure, the use of any abrasive compounds is not recommended during assembly.

When working with fasteners must be borne in mind that bimetallic radiators use left-handed and right-handed thread.



Before installation, you must select the appropriate battery connection scheme (diagonal, side, bottom). If the device is attached to a one-pipe system, it will be rational to install a bypass, which will ensure the normal functioning of the heating structure when the product is connected in series.

How to connect the radiator in the room?

To ensure a comfortable atmosphere in the room it is necessary not only to choose the right battery and install it. It is important to take into account the specifics of the arrangement of the entire building.

How to connect heating radiators in a private house

A well-equipped system is important for heating both a large cottage and a compact structure. Moreover, it is desirable that heating creates a comfortable atmosphere in the cold season and is not the largest item of budget expenditure.

Connect radiators in two ways. Both types of wiring (one-pipe and two-pipe) have their advantages and disadvantages.

Advantages of a single-pipe system: simple connection, low cost of materials and equipment, the possibility of using different heat transfer media (water, antifreeze). The disadvantages include a certain number of radiators on one line, the inability to control the temperature, low energy efficiency. Use this system is recommended for buildings that have more than three floors.

In the two-pipe design, different branches are used to supply the hot heat carrier to the radiator and move the cold one. When equipping a private house, a horizontal system is mounted, which has several advantages:

  • in all radiators the coolant has the same temperature;
  • each line can be equipped with a thermostat;
  • easy pipe wiring allows you to install the system in the structure of any area and layout;
  • good energy efficiency.

Disadvantages can be considered a high cost and more complex installation, a large amount of materials.

When installing radiators, different pipe connection options are used:

  • one-sided (side) - pipes start up on one side, with hot water being supplied to the upper part of the radiator, and cold water is being withdrawn from the bottom;
  • diagonal - pipes are connected at the top (hot water) and below from different sides;
  • saddle - pipes are connected at the bottom of the radiator (located horizontally), from different sides;
  • bottom - pipes attached below (installed vertically), and are close by.

The saddle and lower types of connection are characterized by low energy efficiency. Since hot water circulates at the bottom of the radiator, and the upper area warms up slightly. This feature leads to a loss of energy efficiency (about 15%) and slow heating of the room.

The one-sided mounting of the pipes ensures uniform heating of the battery and is characterized by excellent heat dissipation. Due to the particular connection of the lines, it is advisable to use it in homes with a small number of radiators (up to 15 units).

Diagonal design scheme can be considered an ideal option when arranging the heating system at home. Since it is easily mounted in homes of any size and has a high heat transfer rate (losses are about 2%).



How to connect a radiator in the apartment

In high-rise buildings, two methods of heating are used: one-pipe and two-pipe. They determine the connection option for heating devices.

In the case of a single-pipe type, the coolant moves through a vertical pipe to radiators connected in series. In such a system there is no pipe for the withdrawal of waste water. The design is easy to install and easy to maintain, economical consumption of materials, since there is no need for jumpers, connecting elements and reverse risers. The disadvantage is the different degree of heating of the apartments on the upper and lower floors. Sometimes there is a difference in air temperature even in the rooms of one apartment.

In the two-pipe system there are already separate pipelines (especially for hot water and cooled down), which increases its energy efficiency.



In apartments, the batteries are connected in two ways: serial and parallel.

  1. In a sequential version, the batteries are located directly in the system. There is no possibility of regulating the temperature of the radiator, and for the repair of the heater it is necessary to turn off the entire system and drain water from it. In apartments with such arrangement of heating, cast-iron and tubular heating devices are installed.
  2. With the parallel method, the batteries get coolant through a pipe connected to a common riser. In the same way, cooled water is removed. Installing ball valves allows you to block the movement of coolants and repair equipment without affecting the neighbors.

The main disadvantage is the low warm-up of batteries when the pressure in the network decreases. In this version of the heating system using aluminum radiators and bimetallic.

There are no strict requirements for choosing the type of battery connection. The diagonal version is best suited for multisection models. For systems located in the floor, use the bottom connection. The most typical and common is the side connection of the battery.



Recommendations on how to properly connect the radiator

When mounting the battery on fasteners, it is important to check its position with a level, otherwise air plugs may appear in the future.

It is undesirable in the apartment to voluntarily change the place of installation of radiators or connect additional batteries, as this may affect the heating mode of the neighbors in the riser.

The battery connection option affects its thermal efficiency. This moment must be considered when studying the parameters of the device declared by the manufacturer.

In principle, any radiator can be installed independently. The complete set of heating devices includes not only the necessary details, but also the detailed installation instructions for the product. However, if there is no installation / disassembly experience, then it is advisable to turn to professionals. That specialist will determine - how best to connect radiators, taking into account the characteristics of the room and building.
