How to choose and what to look for?

To choose an effective and reliable model, you should know some of the nuances of cast iron radiators.

• If your room has a standard height ceiling, the power of 120 watts per square meter will be enough.
• Each section weighs from 3 to 7 kg. Once the battery is installed, the number can be increased or decreased.
• The standard arrangement of batteries is wall-mounted, but there are also floor-mounted ones on sale. For wall-mounted ones you need to choose a sturdy bracket or hooks, for floor-mounted ones there are "legs".
• The old type models contain 1.5 liters of coolant, in the new ones it is less - up to 0.8 liters.
• The old have a pressure of 8 atmospheres, the new - 12-18 atm.

Types of cast iron radiators and their brief description

1. Older samples of cast iron batteries, though unattractive outwardly, but their characteristics are almost as good as modern ones. They are cheap (one section - about 350 rubles), the size can be different, so you need to think in advance whether this radiator will fit under the window sill.
2. The new generation radiators fit better into modern interiors: they have a flat surface and a flat front panel. Good quality models are made not only in Europe (Italy and the Czech Republic), but also in Russia.
3. Designer models are not hidden, but are displayed as a decoration of the room. Most are stylized like products of past centuries, have bas-reliefs, drawings and decorations on the surface, twisted legs. The size range is wide.

Advantages and disadvantages of cast iron radiators

Advantages:

1. Resistance to corrosion - one of the most important properties of cast iron. When moisture falls on its surface, a thin protective film is formed, which does not allow corrosion to get inside the cast iron.
2. As a coolant can be used not only water, but also oil, antifreeze propylene glycol.
3. Cast iron radiators do not cool down for a long time after shutting down.
4. Unlike steel and aluminum radiators, cast iron radiators calmly and without loss endure a long stay without coolant. Therefore, the buyer should not worry that something bad will happen to the heating system during the period of summer utility repairs.
5. The peculiarity of the design allows you to repair and improve cast iron radiators without problems. Make it longer or shorter, replace the old part with a new one, throw the element away - no problem!
6. The service life of cast iron elements is not insignificant - 40-50 years.
7. They are affordable.

Disadvantages:

1. Very heavy, require reliable mounting to the wall or a special stand, and older models are also cumbersome.
2. Rough surface attracts dust and makes cleaning difficult.
3. Heat transfer surface area is less than that of steel and aluminum, and it takes longer to heat cast iron radiators.
4. You can not set the automatic temperature control.

Aluminium or cast iron radiator - which is better?

Aluminum models are elegant in appearance and several times lighter than cast iron models. They have a high heat output and an affordable price.

Unnecessary sections can be easily removed, or you can add a few more if necessary. But if the model has not been treated inside with a special polymer composition, then over time it will begin to oxidize from the water.

And tap water, often too hard, saturated with salts and other chemical compounds, is harmful to it..

Cast iron radiators are now produced in different shapes and colors.. They are not afraid of corrosion, can withstand water hammer, for a long time are able to warm the house even after turning off, and serve for a long time.

However, automatic regulation of cast iron radiators is not possible, they need a lot of water for normal operation, and they weigh a lot..

They can be put both in private houses, and in an apartment building.
