In winter, there is no way to do without heating, and the heating system is unthinkable without radiators. It depends on them how comfortable the conditions will be, how evenly the heat will be distributed, how quickly the room will warm up, and how safe the whole heating system will be. How to find such a radiator that would be most suitable for specific conditions, look good and warm well? The answer is simple: it is important to choose a reliable seller and refer, for example, to http: //spb.aport.ru/ radiatory_otoplenija / cat6149, but at the same time to be aware of some of the nuances and features of some types of radiators yourself. These subtleties require close attention.

The first thing that needs to take into account when choosing a radiator, is the type of heating system and its inherent features. So,

should be taken into account coolant temperature, pressure, chemical composition, work stability and much more. If in a house with independent heating , you can create optimal conditions for the radiator itself: supply purified water to it, and keep the temperature and pressure normal. When it comes to apartment buildings , which are connected to central heating, circumstances change a little. Temperature fluctuations have become quite common here, water hammer when the water pressure rises sharply, and this is not to mention the composition of the incoming coolant: it can have an acidic or alkaline environment, which leads to corrosion, be too hard, contain particles of rust that go therefrom the pipes. Not every radiator can withstand operation in such conditions, which can lead to failure.

When buying a radiator, it is better to clarify as much as possible the allowable temperature of the and maximum pressure , at which there will be no failures and malfunctions. These data should be compared with the parameters of the heating system: for example, for most high-rise buildings with a single-pipe open system, the limiting temperature is 1050С, and the pressure is 10 atm, but this is without taking into account water hammer. Even better, of course, if the radiator has enough power to become a reliable and durable element in the heating system. It is also important to take into account the heat transfer, which depends on how quickly the room will warm up after the start of heating. In addition, we should not forget about the appearance, and about the cost. The whole complex of the listed parameters depends on the material of which the radiator is made.

Cast-Iron Radiators

Cast-iron radiators have been used in domestic spaces for about a century, and, oddly enough, have retained their popularity until now. They owe such popular love to their to the numerous merits of .The first and one of the most important advantages is an affordable price, because in this parameter cast iron batteries will give odds to any other. In addition, they are the best suited for operating conditions in modern apartment buildings, as they withstand temperature differences, and any pressure, and frequent water hammer without any problems. Even if an emergency shutdown of heat happens, the cast iron radiator will give off heat for a long time, and it warms up relatively quickly.

Cast iron is a material that is resistant to hard alkaline water, air caps, rust particles and other impurities in the coolant, which can have a detrimental effect on all other radiators. All this still makes paying attention when choosing exactly to cast iron radiators. They are excellent suitable for apartments with centralized heating , but in private homes they can be used with the same success.

With all its advantages, the cast iron battery cannot be called stylish and unusual, and in its classic version it is unlikely to be able to decorate the interior, and the owners will immediately have to think about how to disguise it. But you can find an argument for this fact: modern manufacturers began to create real works of art, rather than radiators - they decorate them with monograms, paint in bronze or copper, and as a result such detail becomes an excellent decoration of the classic interior.

Blame cast iron radiators and too cumbersome, but nothing can be done about it. In addition, they have a high inertia, which will save the owners with abrupt shutdowns of heat, but prevents if you want to equip the radiator with a thermostat.

Aluminum Radiators

Aluminum radiators are the main competitors of cast iron, and today occupy key positions in the market. The recognition and trust of numerous users have earned such batteries for their ease of installation, good looks, high heat transfer and light weight. And due to the fact that the number of sections in such radiators can be completely arbitrary, they become truly the universal version of .In addition, they can boast a low inertia, so they can be equipped with a thermostat, and the amount of coolant here will require a minimum.

With all its advantages, aluminum radiators should be recommended to use only in private homes with independent heating .The fact is that they are sensitive to the composition of water and with an elevated alkali content in water, corrosion can begin. The situation is somewhat saved by a protective inner coating, so you need to make sure that it is present before you buy it. The sectional structure turns into not only advantages, but also disadvantages, since there is a possibility of leakage between sections. As for resistance to water pressure, this type of battery is not in the lead, withstanding up to 16 atm, which means that the hydraulic system, unfortunately, can even damage the new radiator.

Special attention should be paid to the appearance, because aluminum radiators are among the leaders in this parameter. They are not only the most light and cute. Designers constantly work on them who easily turn such a functional element into an interior decoration of any style.

Steel radiators

Steel radiators - another great option for rooms with individual heating .They can be panel and tubular, but the appearance in any case remains at the highest level. Panel can heat the air in the room not only due to radiation, but also through convection: the heat comes out through the walls and through the grate on the upper end. The obvious advantages of these batteries include an affordable price, good heat dissipation, low inertia, resistance to corrosion, and the appearance leaves only pleasant emotions. All this makes such radiators an ideal option for homes and institutions with individual heating.

For ordinary apartments, such radiators are suitable only with a big stretch. Although they demonstrate excellent performance, their installation in this case is a huge risk, as they are sensitive to the presence of oxygen in the supplied coolant, do not withstand pressures of more than 16 atm and temperatures of more than 110 degrees.it would seem that they optimally fit into the parameters of many heating systems, but still need to be adjusted for the instability of their work.

Bimetallic radiators

This type of battery combines dignity aluminum and steel batteries , can be used both in a private house, and in an apartment with centralized heating. This is one of the most reliable alternatives to the cast-iron radiator, which has a more attractive appearance, but also a higher price.

Since these batteries consist of two metalv: the ribs are made of aluminum, and the pipeline is made of steel, they accumulate the advantages of the two materials. So, steel makes the product resistant to corrosion and to the composition of the incoming water, and aluminum is responsible for heat transfer and stylish design. Such a product is durable, and on sale you can find radiators painted in any color, and at the same time it is unnecessary to tint and update the coating layer regularly, as is the case with cast iron batteries. Numerous manufacturers claim that such radiators can work for about 40 years, while maintaining pressure up to 30-50 atm and temperatures up to 1300С - a good stock for modern apartments.

As a result, we get actually an ideal radiator, which can only scare users away with price. But he has other drawbacks: he is sensitive to an increased oxygen content in water, and over time can accumulate slag deposits.

Copper Radiators

These radiators differ from all the others in that they are made of a single pipe and without impurities of other metals. Among the advantages of of these products is their high thermal conductivity: it is 2 times higher than that of aluminum, and 4-6 times higher than that of steel and cast iron. That is why the room with a copper radiator will heat up instantly, and it is not necessary to supply much heat transfer to the system due to the design features of the battery, and as a result it warms up already 3 minutes after the heating is turned on. That is why this type of radiator is great for use in private homes. In addition, the copper radiator is characterized by low inertia, so it can easily be supplied with a thermostat, through which to create the optimal climate in any room.

Copper has a high corrosion resistance, it is almost not affected by aggressive environments, so water with a high alkali content is not capable of destroying the radiator from the inside. That is why these batteries are recommended to be installed even in apartment buildings, which makes the copper radiators universal .

So what to buy?

In principle, from the above, everyone can already conclude which type of radiator is most suitable for specific conditions. So, if the for centralized heating is still the best option is the cast-iron radiator , which does not care for high temperatures, neither sharply increasing pressure, nor the composition of the coolant that is dangerous for other types of materials. Yes, and he heats the room relatively quickly, and is inexpensive, so it is available to everyone. Of course, you cannot connect the thermostat to it, but you can do without it, but you can beat the unsightly appearance of the “accordion” by using the hidden resources of your imagination. Aluminum radiators in an apartment building can be used only at your own peril and risk, and is the only alternative to a cast iron battery - the bimetallic radiator, which benefits both in weight and appearance, but because of its high cost, it remains inaccessible to many users.

In private homes, everything is much simpler - can use any radiators that suit in appearance and price. As a rule, autonomous heating systems are distinguished by more or less stable operating systems, and the water is additionally treated, therefore, no temperature and pressure are observed here, as is the supply of hard alkaline water with dirt particles. That is why the best option in this case - aluminum radiator , which is simple to install, light, beautiful, has good heat dissipation, and at the same time inexpensive. steel radiators also fit perfectly into individual heating systems because of their combination of characteristics, and they can also be installed in multi-storey buildings, but there is some risk. But copper are great in both cases, , but do not differ affordable price.

We calculate the required power.

Power, or efficiency of heat transfer from the radiator to the consumer, must be taken into account in any case, because if you make a mistake with this parameter, the radiator, whatever material it is made of, will not bring the desired result. Calculate the power needed, based on a number of parameters, incl.type of building, number of windows, type of windows, number of exterior walls, ceiling height, room area, etc. Getting the final number, it is compared with the power of the selected type of radiator and determine the number of sections. For example, for a room with a wooden window and one door, with a ceiling height of 3 meters, you need a radiator with a capacity of 90 W per square meter. The power of the main types of radiators per one section is as follows: cast iron 90-140 W, aluminum - 180 W, bimetallic - 190 W, steel - from 450 to 5700 W for the entire radiator. Thus, it is possible to obtain the optimal value of power and number of ribs, so that the room is neither hot nor cold.

In conclusion,

Since the radiator is an essential part of the entire heating system, it is worth paying close attention to its choice. The only and universal answer to the question, what kind of radiator is better, does not exist, otherwise there would not be so many kinds of different batteries. Each purchase must take into account the peculiarities of the operation of its own heating system, clearly assess the operating conditions, requirements for appearance and cost, and from the aggregate of these data choose the best option.
