How to choose a radiator?

Fall is coming to an end, which means that the window will be colder by the day.Therefore, it is important that the house was always cozy and warm.We'll talk more about how to choose the radiators for the home.

How to choose a radiator: Tips

First of all, check the reliability of their heating system that will keep you warm on winter evenings.Perhaps it is out of order.

should be aware of the fact that the heating system is the center of the radiator.Water heated to a certain temperature, circulating through the tubes, eventually enters the radiator, which heats the room.

From room type in which you live, the root will depend on the choice of the radiator.If you live in an apartment, your choice on the open heating system, and if in a private home, use a closed system.This feature will also affect the performance of the radiator - namely, pressure and coolant temperature.

details on connecting the radiators, you can fi

nd in our article How to connect radiators.

As for coolant pressure, it is important to take into account the operating and test pressure.All information about the pressure you should get in the housing and communal services.We note only that the operating pressure is constant for the duration of the heating season, and the test - served only one time per year, for a short time (a few hours) to determine the readiness of the heating system.

Comparative characteristics of radiators


most common type of radiators, which was used for many years.Despite the fact that today the market represented a huge range, many prefer it to the cast iron radiators.And rightly so do it.

Cast iron radiators are characterized by their strength and durability.And all because the weight of only one section, excluding water reaches not less than 7 kg.

They are also resistant to corrosion, which can be formed by supplying the pipes tight, contaminated water.Cast iron radiators to cope with the pressure drop in the case of a sudden shutdown of heating for a long time will retain heat.But, at the same time, these radiators do not heat up quickly.And the impressive dimensions complicate its transportation and installation.

Price one section varies from 5 to 25 euros.Substantially affect the price of the appearance of the radiator.Currently, cast iron radiators can boast a huge variety.Despite its awkwardness, they may look sophisticated and elegant thanks to the design of monograms, painting in copper, bronze and other colors.

Aluminium Aluminium radiators is considered to be the successors of iron.They have appeared on the market about 30 years ago, but is already in demand.

You can come across as a Sectional (collapsible) and solid (non-collapsible) radiators.The advantage is the ability to breakout to choose the number of sections.That is, it is possible to dismantle the unnecessary section, or, conversely, to add them if necessary.This will effectively heat the both large and small spaces.But there is a risk of radiators collapsible sections of damage at the connection, while the collapsible can last much longer.

Low weight, high thermal conductivity - all doubtless advantages of aluminum radiators.The disadvantages include susceptibility to corrosion of aluminum.To prevent this, the coolant must meet the high requirements of the chemical.

price of one section from 10 to 15 euros.Aluminium radiators perfectly fit into any interior thanks to a wide choice of models.


Externally are cast structure consisting of ribs, which are interconnected by vertical channels.steel Radiators better suited for private homes.In the apartments the heating system in the coolant contains a large amount of oxygen to which the steel radiators are very sensitive.They do not take up much space.They have a large amount of heat, which reduces the amount of coolant.At the same time, the radiators do not tolerate sudden change in pressure.

Steel radiators are divided into panels and tubular.Tubular radiators powerful panel, but the higher the cost.

tubular radiator cost per 1 kW of heat output - 130-150 euros.


If you can not choose between aluminum and steel radiators, pay attention to the bimetal.They are made of aluminum alloy and steel.The basis of the radiator steel (inner part), which by contact with water, does not cause corrosion.The outer part is made of aluminum, which has high emissivity.

All together allows us to speak about the reliability of bimetallic radiators, which can last for a long time.

When buying such radiator should be aware that they are polnobimetallicheskimi and nepolnobimetallicheskimi.Internal latter design is not only steel but also aluminum, which is not entirely reliable.Therefore your choice on polnobimetallicheskih radiators.

Price for one section is 20 euros.


are made entirely of copper, without any admixture of other metals.Copper has a high thermal conductivity (2 times higher than that of aluminum, and 6 times higher than that of steel and cast iron).The use of copper radiators to quickly warm up the room (from 3 minutes) using a small amount of water.After using it for 3-4 days in an oxide layer formed on the inner surface of the heat sink, which serves as a further protection against chemical damage.The price of copper radiator is much higher than others.

Remember that the technical characteristics play a dominant role in the choice of the radiator.Of course, price and design is important, but do not skimp on this purchase durable.
