Types of cast iron radiators and their brief description

1. Old samples of cast-iron batteries, although unattractive in appearance, are practically not inferior to modern ones in terms of their characteristics. They are cheap (one section is about 350 rubles), they can be different in size, so you need to figure out in advance whether such a battery will fit under the windowsill.
2. Radiators of the new generation 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 Czech Republic), but also in Russia.
3. Designer models are not hidden, but exhibited as room decoration. Most are stylized as 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. Corrosion resistance is one of the most important properties of cast iron. When moisture gets on its surface, a thin protective film is formed that does not allow corrosion to get inside the cast iron.
2. As a coolant, you can use not only water, but also oil, propylene glycol antifreeze.
3. Cast iron radiators do not cool down for a long time after switching off.
4. Unlike steel and aluminum radiators, cast iron ones can easily and without loss endure a long stay without a coolant. Therefore, the buyer should not worry that something bad will happen to the heating system during the period of summer communal repairs.
5. The design feature allows you to repair and improve cast iron radiators without problems. Make it longer or shorter, replace the old part with the new one, throw away the element - no problem!
6. The service life of elements made of cast iron is rather big - 40-50 years.
7. They are affordable.

Flaws:

1. Very heavy, require a secure wall mount or a special stand, and older models are also bulky.
2. The rough surface attracts dust and makes cleaning difficult.
3. The heat transfer surface area is less than that of steel and aluminum, and cast iron radiators take longer to heat up.
4. Automatic temperature control cannot be set.

Aluminum or cast iron radiator - which is better?

Models made of aluminum are elegant in appearance and many times lighter than models made of cast iron. They have high heat dissipation and affordable price..

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

Yes, and tap water, often too hard, saturated with salts and other chemical compounds, harms it..

Cast iron radiators are now produced in different shapes and colors.. They are not afraid of corrosion, withstand water hammer, are able to warm up housing for a long time and, after shutdown, serve for a long time.

However, automatic regulation on cast-iron radiators is impossible, they need a lot of water for their normal functioning, and they weigh a lot.

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