Heating radiators which are best for an apartment

Panel radiators

To get a panel radiator, you need to take two steel sheets, make them fins and weld them together. Connect the structure to the pipes of the heating system, start up the coolant and enjoy life.

There can be from one to three panels. They all come in various sizes. The design is lightweight. Such radiators can be controlled by automatics.

Advantages:

1. Good heat dissipation;
2. Saving water;
3. Small size;
4. Ease of installation (you can install it yourself).

Disadvantages:

1. Painful sensitivity to pressure surges;
2. Difficulty leaving;
3. Sensitivity to the composition of the coolant;
4. Work at low pressure (7-9 atmospheres, short-term - 12-14 atmospheres);
5. Rusting.

Experts advise installing batteries in private houses with a high-quality coolant.

Five installation rules

When installing, take into account the correct location of the batteries and the heating medium supply to them.

If you want to save on energy costs for the boiler, install a two-pipe heating system.

Unlike the traditional "Leningrad" (one-pipe connection), you can regulate the temperature in each room of a private house.

• Take into account the place where the links are connected, leaving at least 20 centimeters for the process connection on the mounting side.
• Ensure optimal convection of warm air through the free space at the bottom and top of the autonomous heating radiators.
• Be aware that the installation of heat exchangers in design niches, screens leads to a loss of heating power. Sometimes this value exceeds 25%. Compensate for "underheating" by increasing the number of sections.
• Install Mayevsky and ball valves on heating radiators. This will allow not only airing, but also draining the water from the pipes to clean the system.

Copper radiators

Copper radiators compare favorably with other heating devices in that their circuit is made of a solid-drawn copper pipe without the use of other metals.

The appearance of copper radiators is suitable only for fans of industrial design, so manufacturers complete heating devices with decorative screens made of wood and other materials.

The pipe with a diameter of up to 28 mm is complemented with copper or aluminum fins and decorative protection made of solid wood, thermoplastics or composite materials. This option provides effective heating of the room due to the unique heat transfer of non-ferrous metals. By the way, in terms of thermal conductivity, copper is more than 2 times ahead of aluminum, and steel and cast iron - 5-6 times. Possessing low inertia, the copper battery provides quick warming up of the room and allows the use of temperature control equipment.

In terms of its thermal conductivity, copper is second only to silver, by a significant margin ahead of other metals

The inherent plasticity of copper, corrosion resistance and the ability to contact with contaminated coolant without harm allows the use of copper batteries in apartments of high-rise buildings. It is noteworthy that after 90 hours of operation, the inner surface of the copper radiator is covered with an oxide film, which further protects the heater from interaction with aggressive substances. There is only one drawback of copper radiators - too high a cost.

Aluminum

Aluminum conducts heat very well, therefore such radiators provide complete heating of the room.

Dignity

Among the advantages, we highlight:

• High heat transfer rates;
• Small dimensions;
• Quite good working pressure, which is 12-18 atmospheres;
• A light weight.

We also note good heat transfer due to the rapid circulation of the coolant, which is provided by free intercollector tubes. On the market, aluminum radiators are presented in a wide range of models with various sizes, so you can easily choose a heating device for any room.

Aluminum heating radiators

The price of batteries depends on the specific manufacturer, but generally differs in availability, since aluminum is a very common and easy-to-work metal. In European countries alone, where the factories of well-known manufacturers of heating devices are located, there are large deposits of aluminum. The least cost is radiators from domestic manufacturers. Although, if you read reviews about them on the Internet, it is better to purchase more expensive foreign counterparts.

Attractive appearance allows using aluminum radiators not only as a heating device, but also as an element of interior design. Due to its neat shape, the device can fit into almost any environment.

disadvantages

However, aluminum radiators also have their drawbacks:

• Sensitivity to the quality of the heating agent (regular filtration is required, otherwise the system will become unusable in a matter of years);
• Susceptibility to sudden changes in pressure (when filling, control of the pressure level is necessary);
• Weak resistance to corrosion (when buying, be sure to check that there is a protective polymer coating on the surface of the radiator);
• Fragility (service life is 10-15 years).

The increased heat transfer of aluminum radiators affects not only the positive side. The powerful operation of the device quickly lifts warm air upward, which is trapped between the battery and the ceiling. As a result, temperature differences may occur. Before buying a device, it is necessary to calculate the heat required for the room. Otherwise, the floor may not warm up.

Classification

Aluminum batteries are classified into three types by design. They differ in structure and service capabilities.

Solid Aluminum Heating Radiator

Consider these types and try to understand which heating batteries are best for a private house:

1. Solid - stand out for their ductility and durable construction;
2. Assembled sectional - when servicing, you can replace the plates that are out of order;
3. Combined - combine the qualities of the two previous types, but have a higher cost. In terms of functional advantages, they are recognized as the best aluminum radiators for heating a private house. Produced by Global, Ferroli and RIFAR.

sectional aluminum heating radiators RIFAR

The demand for these devices was ensured by an affordable price, increased heat output and an attractive design. This is one of the best options for high-quality heating of your own home. If you follow all the rules of operation, such batteries will last more than ten years, delighting residents with good heating on cold winter evenings.

Aluminum radiator

It is widely used to design a heating system in a private house. They became popular due to their design and high heat output. The cost of such radiators depends on the manufacturer.

Radiators of domestic manufacturers will cost less, but after getting acquainted with consumer reviews, it is worth giving preference to foreign counterparts, but their price is much higher.

When choosing an aluminum radiator for a localized system of your own home, you must adhere to a list of very significant conditions for selection and operation:

• An aluminum radiator is the most susceptible to circulating fluid.It is required to strictly observe the required level of acidity of the water, otherwise such radiators will become unusable within several years;
• Aluminum radiators have a threaded connection. which increases the risk of leakage;
• The high heat output of aluminum radiators has a downside. When the radiators are heated, the warm air flow rises very quickly, which leads to a temperature difference between the floor and the ceiling.

Sectional aluminum radiator

This means that when choosing aluminum radiators, there is a need to make accurate calculations for the area of ​​the room, since the floor can remain cold.

But aluminum radiators also have undoubted advantages:

• Relatively light weight, which makes it possible to mount on drywall walls;
• Sufficiently aesthetic appearance
• The presence of special taps that allow you to regulate the temperature.

The relatively low price, good design and instant heat dissipation are the secret of the popularity of aluminum radiators.

These are quite acceptable radiators for a heating system in a private house. Observing strictly the norms of selection and use, such radiators will heat your cozy home for a long time.

Steel

By design and functional features, these devices are of three types. Then what steel radiators are better to choose for a private house? Let's take a look at the characteristics of each species.

Panel

Also called convectors because heat is supplied by convection (75%). They have a rectangular shape and are two welded panels. The coolant circulates through special dining channels. The battery is lightweight and compact, which allows it to quickly gain and maintain the required temperature.

Panel radiators

Among the significant disadvantages are susceptibility to mechanical damage and low operating pressure. Also, steel panel radiators are destroyed by corrosion.

Steel panel radiators Korado

Manufacturers produce models with a lower type of liner, which allows you to hide pipes under the floor covering. This option is ideal for rooms with an original interior design, in which inlet / outlet communications will look out of place. Among the well-known manufacturers, we will single out Corado, Lidea and Buderus.

Panel radiators Lidea

Sectional

In terms of characteristics, such devices are similar to cast iron radiators, but they have a number of significant differences:

• Internal pressure - 16 atm;
• Increased strength due to welded joints;
• Long period of operation (can work up to 50 years).

Unlike cast iron batteries, these devices are not as widespread due to their higher price.

Sectional radiators

Tubular

In terms of functionality, they generally correspond to panel and sectional radiators, but they are much more expensive. The extra charge comes at the expense of a more attractive appearance, which allows them to be placed in rooms with themed interior design. In addition, it is very convenient to dry things on tubular batteries, which is especially important for families with small children.

Tubular radiators Zehnder

Produced by well-known foreign manufacturers: Zehnder, Arbonia and Delonghi.

What are the threats posed by centralized heating

On the one hand, the supply of heat from the outside is more convenient than autonomous heating - no need to fiddle with installing the boiler and adjusting it. Autumn will come, and hot water will merrily run through your batteries, warming up your apartment.

But not everything is so smooth in the district heating system:

• Water, which has come a long way, contains many chemically active impurities that can corrode pipes and radiators.
• And also small particles of sludge, which inevitably fall into the coolant, scratch the batteries from the inside, after a few years wiping them to holes.
• And the water temperature is not always stable - either the batteries are at room temperature, or it is impossible to touch them.
• And the most important danger is a sudden huge jump in pressure in the heating system, the so-called water hammer. It happens, for example, for the reason that the locksmith too abruptly closed the crane of the pumping station.

Previously, valves with a smooth running were used there, and with the advent of ball valves, it became possible to shut off the water instantly. There is also a water hammer when excess air enters the pipes. A second jump in the pressure of troubles can do a lot. Weak batteries cannot withstand enormous pressure and burst, splashing boiling water, ruining furnishings and damaging neighbors below.

Design features

To create comfortable living conditions in a private house, it is necessary to choose the design of heating radiators.

It depends on the shape of the living quarters, the design of a private house.

Radiators consist of vertical or horizontal tubes, solid plates that create good convection.

They quickly and thoroughly warm up the room.

Tubular

This type of radiator belongs to the premium segment in terms of service life, up to a quarter of a century, design and price. The thickness of the tubes is selected depending on the size of the room. Installation in rooms with floor-to-ceiling panoramic glazing is possible.

European manufacturers supply the market with low tube heaters with a height of 15 centimeters. There are angled and curved heat exchangers. The most expensive and durable construction is considered to be stainless steel tubular batteries. They have only one drawback - the high price.

Sectional

Sections of the same type in such radiators are assembled for a certain power. You can pick it up for any shape and length.

Sections are made from any type of metal used in radiators. This is an economical, low cost option that allows you to vary the number of elements and adjust the temperature.

The worst thing that awaits the owners is leaks between sections and difficulty in cleaning.

Panel

Radiators are two metal shields connected by welding. They are made only of steel, they have the advantages and disadvantages of this type of metal in contact with water. The one-piece surface has high heat dissipation, it can be easily mounted on any walls, including hard-to-reach places. Unlike sectional units, it is impossible to resize in one-piece designs.

Convection

The design of the pipe with fins in the convector radiator ensures constant air circulation in the room.

A copper or steel tube is used as a body, to which mild steel plates are welded. The main advantage of convector radiators is the rapid heating of the room.

Air circulation can raise dust, therefore experts do not recommend equipping water heating with such devices where allergy sufferers live. Convectors are ineffective in rooms with a high ceiling - more than three meters.

TOP-2 cast iron heating radiators

Cast iron radiators can be bought in sections, dialing the required number for the room. Cast iron has a lower heating rate, but long-term maintenance of heat when the heating is turned off. The batteries can withstand more pressure than steel ones and are superior in strength. Such radiators are less susceptible to corrosion and can be installed in open systems and apartment buildings. But they do not look very attractive, they require painting - this is a small minus.

What batteries are better to put in an apartment

We already know what threatens radiators in district heating systems. This is high pressure and water hammer - the rest can be neglected (to some extent). How do you choose heating radiators for an apartment and what are the requirements for them? Everything is easy and simple here, which will be described below.

Resistant to high pressure and water hammer

The best radiators for an apartment are those that can withstand high pressure. The higher the house, the higher the maximum possible pressure in the battery should be. You also need to remember about possible water hammer, so this figure is doubled. Considering that the pressure in the heating systems of high-rise buildings reaches 15-16 atmospheres, then the batteries must withstand a maximum pressure of up to 32 atmospheres.

For five-story houses, models with more modest indicators are suitable, since the pressure here is not so high - you need to navigate 16-20 atmospheres, taking into account possible hydraulic shocks.

Corrosion resistant

Many radiator models are subject to corrosion. Electrical corrosion is especially dangerous, which can occur at the junction of different metals.

Far from pure water flows in the pipes of heating systems. There are also quite aggressive components used to clean pipes and radiators from traces of corrosion. Together with rust and scale, aggressive components eat up metal. And if the same cast iron can still boast of durability, then aluminum under such influence is subject to destruction. Mechanical impurities require the use of a thick-walled metal that is resistant to mechanical stress.

Design and brand

Which heating batteries are better for an apartment, and which ones are better for a house? In private houses, we are free to use any heating batteries, since there we are independently responsible for the absence of water hammer and for the quality of the coolant. Therefore, there we often use fairly cheap radiators, from which great endurance is not required (especially if an open-type heating system is installed in the house).

As for apartment buildings, here you need to pay attention to the most durable batteries from leading brands. For example, it can be heating radiators from Kermi

Global or Fondital.Products from German manufacturers have the best quality, but here you need to be prepared for high costs. But such radiators can be used in heating radiators of any type - they are as reliable and durable as possible.

When it comes to Chinese batteries, there is always a chance of getting into trouble. For example, some manufacturers are openly "trash" by reducing the thickness of the metal. As a result, the batteries are thin and flimsy. Therefore, it is best to rely on European brands.

Modern models of semi-antique cast iron radiators.

Battery design is of paramount importance. Recently, the most popular are thin panel and sectional radiators. They have an attractive appearance and good efficiency - manufacturers do their best to combine high build quality, excellent design and high heat dissipation. An interesting fact is that cast iron batteries began to appear on the market again, but now they have a rather interesting retro design.

It is cast-iron batteries that are able to withstand almost any trouble that heating systems can create. But this comes at the cost of their cumbersomeness and low efficiency.

High heat dissipation

Since we are talking about efficiency, then when choosing radiators, you need to pay attention to heat transfer. The higher this parameter, the warmer it will be in your apartment at the same coolant temperature.

Some models of aluminum and bimetallic heating radiators have a heat transfer of up to 200 W and more per section. For old cast-iron batteries, this figure is about one and a half times higher, but they are more reliable and durable.

Tips for choosing heating radiators

In order not to be mistaken with the choice of a heating radiator for a house or apartment, you need to know which parameters to pay attention to. Here they are:

Radiator working pressure

Before going to the store, you need to know the maximum (at start-up) operating pressure in the heating system. In multi-storey buildings, it can reach up to 16 atmospheres, in panel houses (up to 9 floors) - up to 9 atmospheres. For private houses, a pressure of 2-3 atm is considered normal. Given these data, you can choose a radiator that will withstand the loads indicated here. If this requirement is not met, the battery can simply rupture, which is hazardous to health.

1. Bimetallic radiator - 35 atmospheres;
2. Steel radiator - 6-9 atmospheres;
3. Cast iron radiator - 10-15 atmospheres;
4. Aluminum radiator - 16 atmospheres.
5. Accounting for the power required for space heating

Everything is simple here. To heat one cubic meter of area, 41 watts are required. This standard is established for Russia and several other countries. Let's say you want to heat a room with an area of ​​20 "squares" with a ceiling height of 3 meters. You have to multiply 20 × 3. We get the value 60 (cubic meters). Since 1 cube needs 41 watts of power, we multiply these values ​​and get the number 2460 watts. Next, a heating radiator is selected, taking into account the power of one of its sections.

Section power

The power of one section of different types of radiators:

1. Bimetallic - 180-200 watts;
2. Cast iron - 80-140 watts;
3. Steel - 500-5800 watts for the entire radiator;
4. Aluminum - 190-200 watts.

Select the battery type and divide 2460 watts by the power of one section. You will receive the required number of sections.

Typical dimensions of tubular radiators

The calculations shown are approximate. It is difficult to create perfectly sealed conditions in the room. Heat can escape through the floor, walls, windows. It is necessary to take into account all the nuances, down to what material the house is made of, whether the room is heated under and above you, etc. Instead of 41 watts per cubic meter, you can set a power of 60-70 watts, although it is better to carry out competent insulation so as not to spend money on heating the street. But it is also impossible to achieve overheating, this will negatively affect your well-being.

Unit dimensions

Dimensions depend in part on the power of the radiator. In this case, the location of the device must be taken into account. Most often, batteries are mounted under a windowsill.Measure the distances (height, width) in advance in the place where the radiator will be installed, calculate the power required to heat the apartment and select the heater using these parameters.

Flavoring parameter. Here, the consumer is not limited by anything and is free to choose the unit that he likes.

Manufacturers

Italian manufacturers are considered the best. Good products are produced by German, Austrian, Finnish craftsmen. The manufacturers of the CIS countries are not much inferior to them.

Measure all the features of different types of radiators, make a calculation and make the right choice.
