It’s not just the material, but the construction that determines how efficient the batteries will be in operation.
Assembled from several elements-sections, which are connected to each other with the help of transition joints. The heated area depends on their number.
The number of sections is adjustable: if necessary, additional elements can be added or subtracted. If any of them are out of order, they can be replaced. The “weakest link” of a sectional system is considered to be the connection areas of the elements, where leaks occur most often.
They have an unusual appearance, are economical and give off heat well. Can have a length of 0.3 to 3 m, the number of rows of tubes up to 9. Their shape also varies: standard heaters, batteries combined with shelves, benches, etc.п.
The internal volume of the fluid is relatively small, making it easy to regulate the heat transfer.
Between the two ribbed sheets-panels heating plates are placed U-shaped. The latter are assembled in rows, the number of which can reach up to three. The devices use the principle of convection to transmit heat, which makes them quite effective. Respond well to adjustments. Available in wall and ceiling versions.
Heating your home with radiators
When the question arises on the agenda, what radiators for heating is the best choice for a private home, many of those who are nostalgic about the Soviet cast-iron “accordions”. although bulky, but hot, well warming the room. Indeed, at one time such radiators worked “perfectly”, but now, they are falling into disrepair and are considered obsolete. To replace them

Rules for the arrangement of batteries in the house
In order to make the most efficient connection, you should strictly follow the rules for the installation of heating radiators.
You can highlight the most effective recommendations:
- Placement of radiators in a private home. Heating devices are placed in such a way as to create a heat flow that reduces heat loss. The recommended places to install batteries. under the windows, on the bearing wall of the building.
- Choosing the connection scheme of radiators. Traditionally, systems with forced and natural circulation of the coolant are used, one-pipe and two-pipe. The most effective scheme is considered to be the one with forced circulation.
- Two-pipe systems, with natural circulation of the coolant, are used for cast iron and aluminum batteries. This is due to the diameter of the side connection of the distribution.
- Steel radiators are designed to connect the pipe ¾, which is not enough to ensure the inflow and circulation of liquid naturally.
Methods of connecting the radiators in the country house affect the efficiency of heating. The main disadvantage of the system with forced circulation of the coolant. can not work in case of power outage. The problem is solved by connecting a generator or installing a bypass. Systems with natural circulation are inefficient and require strict adherence to slopes.
If You need to order quality installation of engineering systems (heating, water supply) please contact DESIGN PRESTIGE LLC by phone 7 (495) 744-67-74, We will perform professional installation of the system in accordance with high quality standards.
There are two options for connecting the radiators. top and bottom. With natural circulation the first method is used. The supply of the thermal fluid is carried out through the upper outlet. Bottom connection is used for closed systems with high pressure.
What is the best heating medium to use?
Water or antifreeze can be used as coolant. It is necessary to take into account what type of radiator installed in the heating system.
The antifreeze is not suitable for cast iron and steel radiators. The first have the weak point in the joints between the sections. Under the action of antifreeze gaskets become deformed and leak. Steel batteries are sensitive to the quality of the coolant. Use of antifreeze reduces life.
For aluminum, copper and bimetallic batteries can be used any type of coolant.
For a private house it is better to use steel, cast-iron or aluminum radiators. High cost of bimetallic batteries and the lack of high pressure in autonomous systems makes their installation for heating a country house unreasonable.
Our company installs boilers operating on gas, solid or diesel fuel, as well as electric boilers: the choice depends on the availability of a particular fuel, as well as the needs of the heat consumer.
As a heat carrier the familiar fluids can act: water, toluene, antifreeze. The last two fill the system, which is expected to use as needed (toluene and antifreeze are frost-resistant, t.е. do not freeze in sub-zero temperatures) or in areas where there are interruptions in electricity and gas supply.

What radiators for heating are better for a private house
The creation of a heating system is one of the most important stages in the construction of a private house. The comfort of the residents depends on how thorough the approach to the design and installation of heating. The radiators for the heating. which is better for a private house? The question is really important, because the right choice of equipment will allow you to create an efficient and inexpensive heating system that will be happy with warmth and comfort in the cold season.
You are renovating your apartment or house. The question of what to replace the old cast iron radiators. I want to choose something more stylish. Some neighbors praise aluminum, others praise steel, others praise bimetallic radiators. Let’s find out what they differ from each other.
There are three kinds of batteries in Leroy Merlin: aluminum, steel and bimetallic. We consider the advantages and disadvantages of each type.
- easy enough installation and care;
- stylish design;
- high heat output: instantaneous response to the temperature of the carrier, rapid heating and cooling, and therefore, energy saving;
- high working pressure, 16 atmospheres;
- variety of shapes;
- low weight of the section;
- optimal price.
- demanding to the quality of the coolant: high alkali can lead to rust and gas formation, the joints between the sections can begin to leak;
- periodic venting of the top manifold by means of an air vent valve;
- the most vulnerable parts of aluminum radiators. screw joints of the sections (if compared to steel).
- Steel. Batteries made of this material is best used in private homes: steel radiators require a stable pressure of the coolant. Lasts for 15-25 years (with purified water and pressure control).
- Fast heating up and cooling down (in this aspect they are slightly inferior to aluminum radiators);
- high heat output;
- stylish design
- optimal ratio of cost to capacity;
- Low working pressure from 8.7 atm.
- may not be able to withstand the pressure of hydraulic shocks;
- Do not react well to oxygen, which can enter through the pipe system. Steel radiators can be panel or tubular.
Tube batteries are arranged simpler than panel ones, respectively, they are more reliable. They have no inter-sectional connections, so the risk of leaks is lower. Tubular radiators are more resistant to water hammer. The design of such radiators resembles a ladder of vertical tubes. The most advantageous look colored radiators, they can decorate the modern design interior.

Panel radiators have a more complex internal structure: under the hull is hidden steel zigzag plates that are connected by spot welding. The resulting cavities serve as channels through which the hot water circulates. One of the advantages of panel radiators. flat surfaces, it is easier to clean the dust from them.
The radiator is one of the most important devices of interior decoration, which creates heat and comfort of any house.
There are two steps in the process of selecting a radiator:
Modern water heating radiators come in different types, depending on the material of manufacture and construction. When choosing a radiator, experts advise to pay attention, above all, to the material of the sections, because it affects the heat output of the future battery, its weight and durability.
- Aluminum radiators. lightweight, durable, reliable and aesthetic heating devices. The aluminum radiator design has a well-developed surface. Combined with excellent thermal conductivity, aluminum radiators are highly efficient and transfer 50% of their heat through radiation and the other 50% through convection.
- high heat transfer
- Large cross-sectional area of intercollector tubes
- High working pressure 10-16 atmospheres
- elegant design
- Low weight of the section
- optimal price
- Possible corrosion in heating systems where ethylene glycol carrier is used as a heat transfer medium.
- There is a need to bleed air from the upper collector with the help of a bleeder valve.
- Least solidity of aluminum radiators. Screw joints of the sections (in comparison with steel).
Among others, aluminum radiators have proven to be the most effective heating devices, which are used in private houses, offices and apartments of houses of different floor levels.
- Bimetallic radiators. devices of double construction and doubled benefits. These robust and durable devices successfully combine the advantages of aluminum and steel radiators, thus opening up new aspects of quality heating.
Bimetallic radiators inherited from aluminum radiators high thermal conductivity and the ability to withstand high pressure, from steel. strength and corrosion resistance.
- high heat output,
- resistant to low quality coolant,
- high working pressure (from 20 atm),
- durability (lifetime. up to 20 years),
- small volume of coolant in the section,
- elegant design.
- also these radiators of Monolit series can be used in steam heating systems.
- high price (15-20% more expensive than aluminum radiators),
- smaller than that of aluminum radiators the area of the flow cross-section,
- Hydraulic resistance of bimetallic radiators is greater than that of steel, therefore, in heating systems, where this type of radiators is installed, more energy is required for pumping the coolant
Bimetallic radiators have proven their worth and are able to withstand continuous high-pressure loads, successfully withstand water and pneumatic shocks.
Specialists advise their use where additional reliability is required. in apartment buildings and multi-storey office buildings. In private homes and cottages such radiators are used rarely, in connection with the low pressure in the closed heating systems (up to 2 atmospheres) their use may not be appropriate.
- Steel radiators are used mainly in individual heating systems, characterized by low inertia and simple construction. Radiators of this type are made of two steel plates 1.25 mm thick, in which grooves are stamped, forming headers and connecting channels. The advantage of this radiator is the immediate response to the temperature of the medium, i.e. the rapid heating up and cooling down, which leads to a maximum efficiency, especially when using modern thermostatic equipment, such as thermostatic valves and thermostatic head.
- high operational reliability due to the absence of detachable joints in the construction of the device, unlike sectional type radiators, such as bimetallic and aluminum ones.
- Availability in the nomenclature of radiators both side and bottom connection;
- optimal price-quality ratio
- 1/2″ connection saves on supply pipelines by using a smaller diameter, and eliminates the need for additional threaded transitions
- the package includes a complete set for installation of the radiator;
- high heat output.
- not recommended for open heating systems; reacts badly to the oxygen in the pipe system)
- Rusts when the coolant is drained
- reacts poorly to oxygen trapped through the pipe system
Steel panel radiator. the best option for heating a country house, a private home, as well as for any room. It is not recommended to install steel heating radiators in wet areas.
- Cast-iron radiators presented in the Russian market not only as the Soviet classics, but also in a modern design, are the basis of the infrastructure of heat supply of many countries. They are characterized by considerable resistance to corrosion of materials, high pressure and various impurities.
- high thermal inertness (holds heat for a long time)
- high wear resistance
- durability (service life. about 50 years)
- working pressure (10. 15 atmospheres)
- easy to use
- low cost
- long-term heating
- do not allow for rapid changes in temperature and heating intensity
- high weight of the radiator
- low heat output
- need for painting
- do not have convection, gives out heat only near itself, due to this the room is heated more slowly and unevenly.
Cast-iron radiators continue to be purchased and used successfully in central heating systems and systems with natural circulation. It is not recommended to use cast iron radiators at the autonomous heating.
The final decision in favor of a particular type of radiator should be taken on the basis of the basic characteristics of the heating system for which the heater is designed.
- Central, or individual heating system in the house;
- operating and test pressure in the heating system;
- type of heating system. One-pipe or two-pipe;
- maximum temperature and PH of the heat carrier.
Calculation of heat output and number of radiators
Determining the type of radiator you need to pay attention to the thermal capacity, the value of which depends on the specific room. The amount of power consumption depends on a number of indicators:
Selection of heating radiators by heat output
Heat output calculation is given for a room with standard ceiling height up to 3 meters and window dimensions. up to 1.5 x 1.8 m. In general, for ease of calculation and good insulation of the room, you can take one section of the radiator per 1.5-2 square meters of heater area. м. room area.
Thermal power for all types of radiators is different:
cast-iron radiator. 80-150 W (for one section); steel radiator. 450-5700 W (for the whole radiator); aluminum radiator. 190 W (for one section); bimetallic radiator. 200 W (for one section).
Power of the radiator, sectional or whole, is specified in the technical specifications provided by the manufacturer. The optimum temperature of the coolant, water, under these conditions should be 70 ° C.
Consumable materials: ball cocks, tees, jumpers (bypass), extension pipes, brackets, plugs, fittings.
Paint materials: primer, paint for metal surfaces, patina.
Convector radiators differ from other types of radiators method of heating. For example, aluminum sectional radiators heat the ambient air, which causes it to rise upwards, while cold streams remain underneath. The convector radiators consist of plates with air ducts running between the ribs. The air circulates in these grooves, heats and mixes with the cold, evenly warming the environment. Circulation is constant, so even a large number of partitions and pieces of furniture will not be an obstacle to heating the room.
The advantages of convector radiators are that they:
- Resistant to rust and scaling because they are made of corrosion-resistant materials such as copper.
- Conserve heat transfer fluid.
- They heat up quickly.
- Warms any room quickly, including high ceilings.
- Easy to install.
- They look aesthetically pleasing.
- Ergonomic, low weight.
- Safe, as the entire heat exchanger is covered by the casing.
The possibility to hide the radiator behind a box can also be written in the advantages. The only disadvantage is a high cost of the model, which is fully justified by the characteristics of the radiator.
Choosing heating radiators for a private home, which is better and suitable specifically for your case, pay attention to the capacity of models. To calculate the required index is simple: so, if the room has a ceiling height of 3 m, there is one window and one door, then to heat its 1 sq. м. 100W are needed. If there are external walls, you should add 30% for each. If there are 2 walls and 2 windows, we add 30%.
Tip: For the easiest calculation of the required number of sections you can use the formula: K=S(100/R), where K. Number of sections, R. is the heat output of the section, S. room area.
Note! No matter how good and expensive batteries you bought, they will not work well if you install them incorrectly.
When choosing heating radiators, pay attention to the materials of which they are made:
- Aluminum. Are in greatest demand due to the high heat output of the material. They are lightweight, easy to transport and install.
- Bimetallic. Externally indistinguishable from aluminum radiators, but inside the case have a tubular steel core. Highly corrosion resistant, resistant to pressure surges and durable. They have a good heat output and low thermal inertia.
- Steel. Composed of welded metal panels. Simple design and compact size makes it easy to install radiators with your own hands. With a good heat transfer performance, they save energy and are inexpensive.
- Cast iron. Massive classical batteries used in many houses in Russia. Durable, resistant to corrosion, long heating and cooling, which allows you to keep heat after turning off the heating.
To buy heating radiators with the right characteristics, take into account the size of the room where you plan to install batteries. The larger the area, the more heating panels or sections should be at the radiator. To regulate the temperature in the radiators, on sale are special thermostatic fittings kit.

Which metal radiators to put in the country house
In the market of heating equipment presents a large number of battery designs. According to their device, all heaters can be divided into the following types:
There is also a classification according to the metal used in the manufacture of radiators. It is customary to distinguish between the following equipment:
Each of the metals has its own performance characteristics, heat transfer coefficient and other features. To determine the best radiators, you should consider in detail the disadvantages and advantages of each.
Cast iron radiators. a classic, time-tested
Sectional batteries. the main advantage of cast iron is the high quality and durability of the metal. Thick-walled cast iron makes batteries almost eternal. The advantages include:
The disadvantages are the low heat output, ugly appearance and large size of the device, stealing the free space.
In case of an emergency shutdown of the boiler, the heated cast iron radiator will cool for a long time and will not let the temperature of the coolant drop quickly.
Bimetallic, aluminum and copper batteries. high heat output and reliability
If we talk about heat output, you will not find better copper and bimetallic radiators. The radiators withstand high pressure and practically do not react to the quality of the coolant.
It is not reasonable to install bimetallic models for a private house. Radiators of this type were originally developed for connection to the central heating.
As an alternative, one can use aluminum radiators that have a lower cost than their bimetallic counterparts. The heat output of radiators is in no way inferior to devices made of two metals.
Steel radiators are a cheap and popular choice
Steel heating devices are chosen most often for independent heating of a private house. It is caused by many factors: low cost, beautiful appearance, good heat emission indexes.
Provides bottom and top connection, possibility of operation in one and two-pipe heating system.
The disadvantage of steel batteries is the susceptibility of the structure to corrosive effects. Another disadvantage is the inability to add power in case of an error in calculation, as in the case of cast iron or bimetallic. It is forbidden to install batteries in rooms with high humidity.
