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.

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.
