How to choose what to put batteries in the apartment - the technique of choice

as heaters in apartments and private houses are commonly used radiators, and the first question that arises in the installation of heating systems - what better to put the batteries in the apartment?The answer to this question depends on many factors, and in order to thoroughly understand it, you must consider the characteristics of the device and the operating conditions of all types of radiators that are currently on the market.

Which battery is better to put the apartment

Today there are four of the most popular varieties of radiators:

  • cast iron;
  • Aluminum;
  • Steel;
  • Bimetallic.

Based on the differences in the shape and material of each type of radiator has its own peculiarities, and they cause their application.

Cast iron radiators

Familiar bulky cast-iron battery, leave in the past.To replace them in the stores there are modern varieties of radiators made of cast iron, which have not only an attractive appearance, but also reliability, proven for decades.

Features cast iron radiators:

  • operating pressure of 6 to 10 atm test - up to 18 atm .;.
  • can work with any pipe systems;
  • can be used for a long time with a value of pH 7-9 central heating systems;
  • Partitioned structure allows you to select the required number of sections, and in the case of reconstruction - to add or remove them.

Cast iron radiators have a number of advantages.They have little corrosion - as a result of the primary reaction with water insoluble black precipitate formed on the inner surface thereof, which prevents the penetration of oxygen dissolved in the water to the metal.The destruction of the cast iron pipes from the inside with the correct operation is extremely slow.Outside radiators are covered with paint resistant and protected from damage.The cast-iron radiators is extremely low gassing, they rage, do not require constant bleed air.

One of the main disadvantages of cast iron batteries is their great weight, complicating their installation.The disadvantages of cast iron radiators can also include inertia - cast iron is slowly heated and slowly cools down, so rapid temperature regulation in a room with cast iron radiators is impossible.

Steel radiators Steel radiators

take the form of a ribbed plate, which is located inside the sealed brewed circuit filled with coolant.A large radiator area and ribbed shape of the surface provides good heat and convection of warm air conditions.Material - steel, has practically the same thermal conductivity as the cast iron, but in the steel wall thickness smaller batteries, so they are heated faster.Steel radiators designed for a working pressure of 6 to 10 atm.

Advantages of steel radiators:

  • shape and appearance make it possible to successfully insert steel radiators in any modern interior;
  • Steel radiators, as well as cast-iron, with proper water treatment in district heating systems are 15-25 years old;
  • Can be used with any pipe system.As in the one-pipe and two-pipe;
  • They are low cost and easy to install.

Before installing steel radiators is necessary to calculate the required number of fins - closed circuit does not allow them to increase the thermal performance and change.

In conditions of elevated pressure steel panel radiators can lose tightness.So do not use them in their homes with the number of floors 5 - system which is designed for a pressure of 6-8 atmospheres.

Aluminium radiators

aluminum radiators have a neat, compact and modern appearance, they are also sold in the form of type-setting sections, so you can choose the optimal number of defined calculation.The height of aluminum radiators is also different, so they can be placed in convenient locations komnaty.Rabochee pressure aluminum radiators from 6 to 12 bar, the test -. To 25 atm.

Aluminium radiators

Aluminium radiators

Advantages of aluminum radiators are obvious:

  • They have a modern look;
  • Heat dissipation is high compared with other heat sinks and can reach 200 watts per section;
  • Aluminium radiators is much lighter than other types of batteries, due to this they are easy to install;
  • You can select the required number of sections;
  • From the outside protected by a polymer coating to prevent radiators from damage.

most basic disadvantage of aluminum radiators is that they can only be used for a long time in closed systems with strict control of the pH of coolant.At the same time you can not use pipes and fittings made of other metals.Aluminum - extremely active metal and in contact with copper or brass to form a galvanic couple, which may cause galvanic corrosion and the appearance of surface currents.Therefore, to perform the coolant supply system to the aluminum radiator is better to use plastic pipes and radiators themselves grounded.

Furthermore, in contact with fresh, oxygenated water reacts aluminum, which product is hydrogen gas.The gas bubbles entering the system, cause unpleasant sounds.Because of this feature during the installation of aluminum radiators must always provide gazootvedeniya system and put the bleed screw.

Based on these characteristics, we can conclude that aluminum radiators, in spite of the low price and excellent heat dissipation, in apartments with central heating is better not to.If it is impossible coolant quality control can not be sure in the long term of their service.

Bimetallic radiators

As the name implies, these radiators are composed of two metals - steel and aluminum, with the advantages of using both of these metals.Inner loop conducting the coolant, in bimetallic radiators made of steel, they can be used in any pressure systems and with different types of pipes and fittings.External plate heat transfer in the space of the room, made of aluminum and, thanks to its high thermal conductivity, excellent heat the room.

Advantages of Bimetallic radiators:

  • High working pressure - up to 35 atm .;
  • Resistance to corrosion in any capacity coolant;
  • Low inertia - radiators, heat quickly, so quickly cool down, and with the help of the coolant flow control, you can quickly lower or raise the temperature in the room;
  • Attractive appearance;
  • light weight, ease of installation;
  • slice design, allowing you to select the desired number of ribs.

The disadvantage is, perhaps, the higher price of bimetallic radiators.As soon compensated for their reliability and long service life.It should also be noted that during the installation of bimetallic radiators need to be sure to comply with the distance to the wall, floor and window sill - it must be at least 4 cm

Summarizing, we can say. For installation in an apartment with central heating is better to choose cast iron or bimetallic radiators,while for low-rise buildings - as steel.Aluminium radiators are best used in closed systems that are connected to the heating boiler, that is, where there is an opportunity to check the quality of the coolant.
