Technical characteristics of cast iron radiators

Technical characteristics of cast iron radiators

Owners of country cottages and houses prefer to use cast iron radiators for heating.

This is often due to lack of gas heating system, which allows you to connect another type of radiator.

cast iron batteries are not afraid of corrosion, they do not take the high-pressure and are not afraid of the impurities in the water.The service life of tens of years.

cast iron radiators do not need repair - are distinguished by special properties.

Advantages and batteries deficiencies of iron

What size, the distance between the axles, number of sections - to these and many other parameters differ cast iron radiators.

make a choice, decide which are suitable radiators in the house, it will be easy, if you look in detail all the technical specifications.

Attention is drawn to the power and pressure indicators on the volume of water in one segment and a maximum temperature coefficient.


radiators made of cast iron is cheaper than bimetal.The reason is that the metal alloy has a modern machinery design, low weight and high quality.

Bimetallic radiators, as opposed to cast iron, can be installed anywhere in the apartment.In the house where Bimetallic radiators, you can adjust the heat transfer process.

True Russian citizens rarely take bimetallic construction, often - cast iron, as guided by the cheapness and the fact how long the machine will last.

But before we determine exactly what is better - cast iron or bimetallic - consider all the technical characteristics of the latter.

Positive characteristics of cast iron batteries:

  • Long lifespan, more than 50 years, due to the strength of the metal;
  • Immunity to rust, which encourages them to be installed in the rooms of the apartment where the summer the water is drained from the battery;
  • Alternative connection through the lower connection, hidden pipes under the floor;
  • Cumulative heat principle, ie in case of disconnection of heating for a few hours, cast iron radiators will not cease to produce heat;
  • Increased inertia when firing coal and wood, which guarantees the heat in the house during severe frosts in Russia;
  • High radiation heat because of the iron battery 70% of the heat transfer, and bimetallic heaters - only 50%.This is because the heat ray method acts on a larger area than-air convection, typical for aluminum heater.

Negative points:

  • Cruiserweight, because cast iron segments are far superior to those in weight, which are made of steel or aluminum.Only one section can weigh 7 kilos.Because the installation is done on the cast-iron batteries capitally prepared and reliable wall.Weight may vary depending on the size and dimensions of cast iron radiators are not small - one section width of 40 cm and height - 58. Sometimes installation is facilitated by the presence of floor stand;
  • Some varieties of cast iron radiators to be coated with paint.Subsequent staining necessarily the skins last coat of paint.Otherwise, the thermal efficiency decreases;
  • Considerable volume of liquid, that is, one battery segment contains a volume of water is 2-3 times greater than in other types of radiators.It follows that the heating system has a higher fuel consumption;
  • Thermal efficiency is characterized by a low index.It is two times lower than the other radiators.It is better to produce heat or bimetallic aluminum heaters.For example, better heat transfer of the aluminum half.

Overview grades of cast iron radiators

Everyone remembers the old radiators Soviet times, which did not differ special beauty.They closed a beautiful canvas, not affecting the capacity of cast iron radiators.

A modern cast iron radiators adapted to decorate the intricate images.

iron art casting looks presentable rooms with different interior.

widely represented foreign analogues cast iron radiators differ most smooth surface inside and out.

This is the reason that the imported models more powerful than domestic.What options are better - the euro or domestic - it's up to the buyer.

main technical characteristics of all grades of cast iron heaters is a table:

domestic version MS-140 Power Rating: 160 watts;
accommodates volume: 1, 45 liters;
pressure: 0.1 MPa;
size (height, depth, width): 588h h108 140 mm; segment weight: over 7 kg.
MS-110 Power Rating: 125W; accommodates volume: 1,036 liters; pressure: 1.2 MPa; size (height, depth, width): 581,4h110h72 mm; Segment Weight: 5, 5 kg.
options Foreign Viadrus Czech production Power Rating: 108 watts; accommodates volume: 0.6 liters; pressure: 1.8 MPa; size (height, depth, width): 560h95h60 mm; section Weight: 4 kg.
Demrad Turkish production Power Rating: 110W; accommodates volume: 0.65 liters; pressure: 1.5 MPa; size (height, depth, width): 560h99h60 mm; section Weight: 7 kg.
Demir dokum Turkish production Power Rating: 208 watts; accommodates volume: 2.1 liters; pressure: 0.9 MPa; size (height, depth, width): 661h203h76 mm; section Weight: about 10 kg.
Konner Chinese production Power Rating: 150W; accommodates volume: 0.9 liters; pressure: 1.2 MPa; size (height, depth, width): 600h96h64 mm; section Weight: about 5 kg.

MS-140 is a classic kind of radiator.It is made in Minsk.Design model MC-140 is similar to the Soviet, that is somewhat cumbersome.

But the model MS-140 significantly improved.

Radiator brand MS-110 - Russian production, and therefore more popular.This battery is made on the basis of MS-140 cast iron, but a manufacturer of material weaknesses corrected the previous model.

Though radiator type is gorgeous to look, but it fit even in a narrow windowsill, unlike MS-140.

Euro radiators from the Czech Republic differ from other rounded and smooth lines that makes us doubt whether they are just made of cast iron.

The equipment for heating the apartment is not bulky, looks cute, needs to be painted.


Types of Turkish batteries varied.Models, copying the old differ unusual design.

Thermal equipment euro from Turkey have unique technical characteristics, having a high emissivity.Some models do not require installation to the wall, they are put on the legs.

Chinese battery adapted to domestic conditions, because they are made for the development of our engineers.Produced various types, some are decorated in marble, others - ornament.

Installation of heating equipment

What would have been the radiators are comfortable and modern, it is necessary to be able to navigate in designs to assembling their own hands did not seem complicated, but the connection - confusing.

First you need to calculate how much need battery segments.This depends on the power of one section.As a rule, cast-iron radiators, the figure ranges from 100-150 watts.

Reflecting on how many segments is required, it is necessary to start from the fact that the battery is good for 10 sections heats an area of ​​12 square meters.meters.

Also, you can simply multiply the floor area is 100 kW, and it becomes clear what the radiator power is needed.

If selected foreign radiator sections need less.This is due to the fact that they have a great heat, because the inner walls of the euro models devoid of roughness, causing less resistance level.

In general, whatever the radiators were not considered, it is not necessary to save on cost.radiator type and its installation in a particular location are of paramount importance.

to install their own hands took place without errors, it is necessary to understand a little scheme.It is also desirable to consult a specialist, and it is necessary to observe safety precautions.

We must not forget that the radiator assembly will turn off the water supply.


For private buildings alike take the system and one and two pipes.And in apartment buildings it is better to install their own hands pipe systems.This will make the battery installation easier.

Installing heating appliance should be carried out at a certain distance in relation to the pipe and its height.

Steps connect thermal equipment with his own hands:

  1. heating off in the riser and the coolant discharge;
  2. dismantling of the last heating unit, which is performed using №3 tong and cutter;
  3. installing a new radiator;
  4. inclusion Majewski tap to exit the air battery;
  5. installation of valves that need, when they carry out repairs to the system and drain the water.

By the way, when is the dismantling, the battery is placed horizontally on the board.Before examining the section is measured up to a key length of the pin.

If dismantling is very difficult, then, where is the nipple, use a blowtorch.

If you plan to dismantle the old radiator, it will not help any tools.Simply perform dismantling as follows: divide the segments with a sledgehammer.


Parallel connection of radiators:

  1. If there is no shut-off valve, perform the same action.When there are valves, they overlap, and only change the heater;
  2. For strong fixing unit using the brackets, follow the airtight connection of pipes with a battery;
  3. When installing parallel use thermostats that allow you to track the number of incoming water to the radiator.

For normal operation of the unit it is necessary to iron one liter of water.Here, the amount of water greater than in other devices.The aluminum water appliances required less than half a liter.

Installation of the steam heating system is just started with the simple operation of the iron battery.

huge period of their life has shown that they work relatively better than other devices, because the period of their work is not limited.

If the installation of the heater with your hands is not clear, it is better not to risk it and call the craftsmen who produce the correct installation and connection.

Especially this concerns the reconstruction of the central heating.

battery Installation

Battery Installation should be carried out in the optimum for this place, so that the area of ​​the room warmed the most.

In areas where there is a window niche, installation and connection of the system takes little space.

Repair radiators

If iron unit after a certain period of service will have to take in for repair, it simply sanded and painted, to avoid corrosion.

Sometimes repair will involve replacement of worn gaskets between sections.

Another reason for which need urgent repair - the formation of holes in the battery, resulting in the observed flow.Repairs can be made with your own hands, brew slit cold welding.

Timely adoption of these measures the service life of the radiator is completed.

correct to carry out repairs in the summer, when there is no connection of heating.Repairs begin only after draining the water.To the floor did not get a single drop of con pelvis.


Sometimes repair iron unit is similar to the process of restoration, so the removal of the old coating is carried out and replacing it with a new one.

When the surface area of ​​the old cracked paint large, to remove this layer is recommended to use a solvent.

To remove old paint, you can use and thermally, heat the battery with a blowtorch.The whole area in which bubbles were formed, was purified with a spatula.

purified radiator is dried and then its surface is treated with a solvent.

Of course, after reading the article would be curious as to how much iron radiator.Of course, the cost varies depending on the country of origin and the quality of the raw materials used.

average reasonable cost of the equipment - 3000 rubles.

Turkish and Chinese heating devices are more expensive at times, and retro models even up to 6 times.

For example, the cost of one section of the domestic models - about 400 rubles, and the price is only one segment of the Turkish model is from 600 to 2500 rubles.
