Owners of country cottages and houses prefer to use cast-iron radiators for heating.
This is often explained by the lack of a gas heating system, which allows you to connect another type of radiator.
Cast iron batteries are not afraid of corrosion, they do not perceive high pressure and are not afraid of impurities in the water. The service life is estimated in tens of years.
Cast iron radiators do not need repair - they are distinguished by special properties.

Advantages and disadvantages of batteries from cast iron
What are the dimensions, the distance between the axles, the number of sections - these and many other parameters distinguish cast iron radiators.
Determine the choice, decide which radiators fit into the house, it will be easy, if you analyze all the technical specifications in detail.
Attention is drawn to the power and pressure parameters, the volume of water in one segment and the maximum temperature coefficient.

Radiators made of cast iron are cheaper than bimetallic. The reason is that the equipment made of metal alloy has a modern design, low weight and high quality.
Bimetal radiators, unlike cast iron radiators, can be installed anywhere in the apartment. In a house where radiators are bimetallic, it is possible to regulate the heat transfer process.
True, Russians take less often bimetallic designs, more often - cast iron, because they are guided by cheapness and by what term the unit will last.
But before you determine exactly which are better - bimetallic or cast iron - consider all the technical characteristics of the second.
Positive characteristics of cast-iron batteries:
- Long service life, more than 50 years, due to the strength of the metal;
- Immunity to rust, which recommends them to be installed in the rooms of the apartment, where in the summer drain the water from the batteries;
- Alternative connection through the lower connection, hiding the pipes under the floor;
- The cumulative principle of heat transfer, that is, in case of heating shutdown for a couple of hours, cast iron radiators will not stop producing heat;
- Increased inertia when burning coal and wood, which guarantees heat in the house in severe frosts in Russia;
- High heat radiation, because the batteries of cast iron transmit 70% of the heat, and bimetal heaters - only 50%.This is explained by the fact that the radiation method of heating acts on a larger area than the convection-air method, which is characteristic of an aluminum heater.
Negative moments:
- Heavy weight, because cast iron segments are much superior in weight to those that are made of steel or aluminum. Only one section can weigh 7 kilograms. Therefore installation of cast-iron batteries is made on a thoroughly prepared and reliable wall. The weight depends on the dimensions, and the dimensions of the cast iron radiator are not small - one section is 40 cm wide and the height is 58. Sometimes the installation is facilitated by the presence of a floor stand;
- Some varieties of cast iron radiators must be covered with paint. At the subsequent painting, the last layer of paint must be smoked. Otherwise, the heat output will decrease;
- A large volume of liquid, that is, one segment of the battery contains a volume of water 2-3 times greater than in other types of radiators. It follows that the heating system has an increased fuel consumption;
- Thermal return is characterized by a low index. It is two times lower than the other radiators. Better produce heat bimetallic or aluminum heaters. For example, heat transfer of aluminum is better by one and a half times.
Overview of brands of radiators made of cast iron
Everyone remembers the old radiators of the Soviet times, which did not differ in particular beauty. They are closed with a beautiful cloth that does not affect the power of the cast-iron radiators.
And modern cast-iron radiators have adapted to decorate with intricate images.
Cast-iron casting looks presentable in rooms with different interiors.
Widely presented import analogues of cast iron radiators are distinguished by the smoothest surface inside and outside.
This is the reason that imported models are more powerful than domestic ones. Which options are better - the euro or the domestic ones - only for the buyer.
The main technical characteristics of all brands of cast iron heaters are presented in the table:

MC-140 is a classic type of radiator. It is manufactured in Minsk. The design of the MC-140 is similar to the Soviet one, that is, it is somewhat cumbersome.
But the MC-140 is significantly improved.
The radiator of the brand MS-110 is of Russian origin, and therefore more popular. This battery is made on the basis of gray cast iron MC-140, but the manufacturer corrected the significant shortcomings of the previous model.
Although the type of radiator is not gorgeous in appearance, but it fits even under a narrow window sill, unlike the MC-140.
Euro radiators from the Czech Republic differ from others in rounded and even lines, which makes it doubtful whether they are made of cast iron.
This equipment for heating the apartment is not bulky, looks cute, needs painting.

The types of Turkish batteries are varied. Models that copy the old, differ in unusual design.
Thermal Euro equipment from Turkey have unique technical characteristics, possessing high heat emission. Some models do not assume mounting to the wall, they are put on the legs.
Chinese batteries are adapted to domestic conditions, because they are made according to the developments of our engineers. Various kinds are made, some are decorated with marble, others - ornament.
You can see the types of euro radiators and domestic heaters on the photo:
Mounting of the thermal equipment
. Whatever the radiators are comfortable and modern, you need to be able to orient yourself in the constructions so that the installation by your own hands does not seem complicated and the connection is confusing.
First you need to calculate how many battery segments you need. And this depends on the power of one section. As a rule, for iron radiators, this figure varies between 100-150 W.
Reflecting on how many segments are required, it is necessary to build on the fact that the battery for 10 sections warms well the area of 12 square meters.meters.
You can also simply multiply the area of the room by 100 kW, and it becomes clear what kind of power radiator is needed.
If a foreign radiator is chosen, the sections need less. This is due to the fact that they have a high heat dissipation, because the internal walls of euro models are free from roughness, which is why the level of resistance is less.
In general, whatever radiators are considered, do not save on the cost. The appearance of the radiator and its installation in a certain place are of great importance.
To install yourself without errors, you need at least a little understanding of the scheme. It is also desirable to consult a specialist, and it is necessary to comply with safety regulations.
Do not forget that the installation of the radiator involves shutting down the water supply.

For private buildings, the same systems are used for both one and two pipes. And in multi-apartment buildings it is better to install one-pipe system by oneself. This will make the battery mounting easier.
The heating device must be installed at a certain distance from the pipe and its height.
Stages of connection of heat equipment with their own hands:
- heating shutdown in the riser and coolant discharge;
- dismantling of the past heating unit, which is performed using the pipe wrench # 3 and pipe cutter;
- installation of a new radiator;
- the inclusion of the Mayevsky crane to exit the air battery;
- installation of shut-off valves, which will be needed when the system is repaired and drained.
By the way, when the dismantling is taking place, the battery is placed horizontally on the shield. Before deconstructing the sections, the length of the key to the nipple is measured.
If dismantling is very difficult, then where the nipple is located, use a blowtorch.
If you plan to dismantle the old radiator, then no tools will help. It is easier to dismantle as follows: break the segments with a sledgehammer.

Parallel connection of heating radiators:
- If there is no shut-off valve, perform the same actions. When there are valves, they are blocked, and only then change the heater;
- For strong fixing of the unit using brackets, monitor the airtightness of the connection of pipes with the battery;
- When the installation is parallel, use thermostats, which allow you to monitor the amount of water entering the radiator.
For the operation of a conventional cast iron unit, one liter of water is needed. Here the amount of water is greater than in other devices. In aluminum appliances, water requires less than a liter.
Installation of steam heating systems just started with the operation of a simple battery of cast iron.
A huge period of their service has shown that they work relatively better than other devices, because their lifetime is unlimited.
If the installation of the heater with your own hands is not clear, it is better not to risk and call the masters who will properly make the installation and connection.
This is especially true for the reconstruction of central heating.
Installation of the battery should be carried out in the optimal place for this, so that the area of the room is heated as much as possible.
In rooms where there is no niche under the window, installing and connecting the system will take up a bit of space.
Repair of radiators
If the cast-iron unit after a certain period of service will have to be handed over for repair, then simply sand it and paint it to avoid corrosion.
Sometimes repairs will involve replacing worn gaskets between sections.
Another reason that needs urgent repairs is the formation of a hole in the battery, resulting in a leak. Repair it is possible to make by own hands, having brewed a crack cold welding.
With the timely adoption of these measures, the service life of the radiator will not end.
It is more correct to carry out repairs in the summer, when there is no heating connection. Repair begins only after draining the water. To the floor did not hit a drop, substitute the pelvis.

Sometimes repair of the cast iron unit is similar to the restoration process, so the old coating is removed and replaced with a new one.
When the surface area of the old cracked paint is large, we recommend using a solvent to remove this layer.
To remove the old paint, you can also use the thermal method, heating the battery with a blowtorch. The whole area on which the bubbles formed is cleaned with a spatula.
The cleaned heating appliance is dried and then its surface is treated with a solvent.
Of course, after reading the article will be curious how much is the cast-iron radiator. Of course, the cost varies depending on the country of origin and the quality of the raw materials used.
The average acceptable cost of this equipment is 3 thousand rubles.
Turkish and Chinese heating devices are more expensive at times, and retro-models even 6 times.
For example, the cost of one section of the domestic model is about 400 rubles, and the price of only one segment of the Turkish model costs from 600 rubles to 2.5 thousand.
