Which heating radiators are better for centralized and

The era of centralized heat supply, which made life for the inhabitants of multi-storey houses cleaner, safer and more convenient, has replaced the stoves and stoves. In this regard, the acute question arises, which heating radiators are better for central heating? The pressure inside the pipe, the properties of the coolant detrimental to the power and safety of heating devices. This topic is half losing its relevance in the presence of autonomous heat, when the owner personally controls the operation of the system.

It is a little about the centralized and local heating

Deciding which radiators are better for a cottage and which for an apartment is logical to start from the heating system, where they will be used - central or autonomous. Surely each of them has its own characteristics, which determine the choice of appropriate heating devices.

Centralized

Central heating is convenient - the boiler room is on the sidelines, and the pleasant heat enters the houses through special pipelines. The most important thing in this process is to bring the coolant to the consumer as hot as possible.

Advantages of centralized heat supply:

1. Relative reliability;
2. Environmental friendliness;
3. Universal boiler equipment allows you to consume coal, fuel oil or gas.

The weaknesses of this system are no less obvious:

1. The high cost of the supplied service, often not corresponding to its quality;
2. Full dependence on the start / end of the heating season and the set temperature;
3. Uneven distribution of heat from the lower floors to the upper;
4. Very hot batteries kill the air microflora, which is harmful to human health;
5. Heat losses reach 30%.

Autonomous

The boiler for a private house or apartment is a local supplier of not only heat, but also hot water for domestic needs. Autonomous systems are usually installed in low-rise buildings, remote from CHP, entrances, apartments or in country houses.

The advantages over centralized heat supply are obvious:

1. No heat loss, because the boilers are located directly in the room;
2. The temperature is controlled directly by the owner.;
3. High efficiency;
4. Minimal negative impact on the environment.

The disadvantages of using heating boilers are very conditional:

1. The cost of project design, equipment purchase and installation;

Note! The instruction states that the installation of individual heating in a multi-storey building is possible only with the collective agreement of the residents of the entrance, at home. In a separate apartment to make it problematic.

1. Regular maintenance, maintenance and repair;
2. Additional costs for a special room to accommodate the installation and storage of fuel (usually refers to diesel boilers).

The main characteristics of radiators

Having a general idea of ​​heating devices, one can theoretically assume which heating radiators are better suited to a particular heating system of your apartment or house.

The most important characteristics to pay attention to in the first place will be:

1. The material of the product;
2. Design features;
3. Type of connection elements.

Cast iron

These products deserve the main attention as the ancestors and old-timers of each Soviet apartment.

Despite the fact that the design of bulky harmonicas has changed beyond recognition, in fact, they have retained such positive qualities of their predecessors:

1. The chemical passivity of cast iron does not allow scale deposits to be deposited, and thick walls resist corrosion for a long time;
2. High thermal inertness;
3. Due to radiation, suitable for high spaces;
4. Heat from the cast iron is the most "healthy" for a person;
5. You can increase / decrease the number of sections;
6. Price - models of artistic casting cost about 25,000 rubles for 6 sections (800 for 1 section of the classic KONNER).

Weak spots:

1. Fragility. With all its massiveness and large weight - the section can pull on 7 kg, they react sensitively to water hammer;
2. A large cross-section of the flow channels prevents the fluid from moving quickly, and the internal surface of the battery quickly silts. Regular flushing is required (once every 3 years);
3. Achilles heel - paronitovye gaskets between sections.

If you choose which radiators are better for central heating, cast-iron models will be a good option. In this case, the rate will be placed on their durability with the known quality of our water.

Aluminum

The list of advantages of these batteries will not be as long as that of cast iron, but it is worthy of attention:

1. Excellent thermal conductivity;
2. The most important advantage of these batteries is their excellent thermal conductivity and, therefore, heat transfer;

1. A small cross-section of the channels together with a smooth surface provides a high velocity of the coolant, which, in turn, prevents the deposition of scale;
2. Maintain temperature on average 110 ° C and pressure up to 16 atm;
3. It is possible to install a thermal switch.

Two factors confuse that preclude the use of an aluminum radiator in a central heat supply system:

1. Aluminum is so soft that the water hammer will simply somnet or tear them;
2. If the neighboring eyeliner is made of copper, which forms a galvanic pair with aluminum, soon you will lose your radiator due to the inevitable chemical reaction;
3. Extremely sensitive to the quality of the coolant;
4. The term of operation is small and reaches about 15 years.

Note! In the autonomous system, where you can precisely avoid the formation of electroplating fumes and control the pH of water, aluminum models are suitable as the best radiators.

Bimetallic

The most important advantage of bimetallic radiators can be called, paraphrasing the well-known saying - that for a bimetal it is good, for aluminum it is a death. This refers to the operating pressure in the system, the boundary indicator of which for some batteries is the initial one for bimetallic - 24 atm. Monolith series Russian batteries are designed to operate at 100 atm.

Successfully combining mechanical stability, chemical passivity of the metal core and thermal conductivity of aluminum fins, the radiators still rust. If you buy a product with a stainless steel core, you can not even think about which radiators are better for central heating - bimetallic will become an ideal option.

Note! Centralized heating is considered to be a testing ground. Therefore, bimetallic radiators that are able to work in such conditions are perfect for stand-alone.

Convectors

Attract attention to mounting options - on the wall, in the floor or on the floor. The convection principle of heat distribution in combination with the built-in installation creates a thermal curtain. The design of the device is a set of aluminum plates mounted on a copper / steel tube for coolant.

The use of a thermostat and a fan facilitates temperature control. The main advantage of the heating device is the integrity of their design - the junction is only at the entrance / exit. The disadvantage is the rapid accumulation of dust between the plates.

The following product specifications will help you make your choice:

1. Maintains the heat carrier to 130 ° C;
2. Permissible operating pressure up to 16 atm;
3. Up to 6 rows in the heat exchanger;
4. Power from 100 to 200 kW.

If you have not decided which radiators are better for autonomous heating, you can choose convectors that warm up the room evenly, but they will also fit into the central one. In any case, you do not have to worry about the galvanic couple, if the neighbors prefer an aluminum radiator - it will not kill you (joke).

Registers

They have the same respectable age as the cast-iron batteries, and are extremely simple in the device - pipe sections connected by welding with smaller pipes. The design may look like a vertical / horizontal or circumferentially curved section, coil. The widest range of colors makes it possible to impart extreme decorativeness to the strict geometry of forms.

What distinguishes registers from the heating devices that are still customary:

1. The cost includes the cost of pipes and welding, which can be done by hand;
2. All joints are welded, which eliminates leakage;
3. You are not limited in the choice of any number of registers, thereby increasing the power of the product;
4. The thickness of the pipe, and hence the life, you choose at will.

Note! Special attention should be paid to pipe fittings. With a considerable length and quantity of them, they will weigh a great deal with water.

As you can see, each type of battery has some peculiarities that allow using them in certain conditions. If you choose what is best registers or radiators, then the latter are best suited to urban apartments. With a huge area of ​​heat transfer the room will be guaranteed warm. Registers of the most unpretentious form can be used in a greenhouse, garage, outbuildings.

In conclusion

The modern market provides the consumer with a lot of types and models of heating devices, from which one has to choose, able to withstand the quirks of central heating. Considering the stability of the radiator to the aggressive environment of water, the pressure inside the system, a successful option is selected that will provide your house with warmth for a long time.
