Cast iron heating radiators: technical characteristics, application and features
The engineer Franz San Galli created the cast-iron heating radiator in 1857, more than 150 years ago. The radiator was eventually made a standard feature of every city apartment. It is fair to say that cast iron heating radiators are outdated and old-fashioned. Is that truly the case?
The aluminum producers of today. In every manner possible, steel bimetallic radiators that took the place of the antiquated cast-iron battery promote the advantages of contemporary heating systems. Naturally, their needs are dictated by contemporary interiors, and the "unsinkable" cast-iron battery on the plumbing’s back is gradually replaced by the desire for the new and revolutionary. Don’t jump to conclusions, though.
Varieties and design features
A cast-iron battery is a prefabricated design made up of multiple identical-sized cast sections. Depending on the heated space’s volume, there can be two to several tens of sections.
Gray cast iron is used in the creation of metallurgical businesses. The radiator section is an oval or round section in the hind structure. Hot water circulates through the channels created by the cavities in the gathered form.
The section is divided in their design as follows:
- on single -channel;
- On two -channel.
Sections are assembled using nipples, and the seams are then sealed with rubber or Paronite heat-resistant gaskets.
Cast-iron radiator dimensions are determined by more than just the number of connected sections. The height of sections can vary from 350 to 1500 mm.
The requirement to heat expansive industrial spaces is linked to the installation of radiator blocks of such remarkable dimensions. The product’s depth can also vary greatly, ranging from 70 to 150 mm, and occasionally even more.
Traditionally, cast-iron batteries are suspended from the wall by securely fastened brackets, frequently beneath windows. In this instance, the wall panel’s indentation must be withstanding.
The release of a floor model of a cast-iron radiator with holder legs has been established by modern industry. This design, which is frequently utilized in private homes, can be installed even across the room.
Main settings
It’s crucial to learn every detail about the technical specifications of cast-iron heating radiators in order to determine if selecting them is worthwhile and what to consider concurrently.
Heat transfer
The slow heating of cast iron, or so-called thermal inertia, is one of its distinguishing qualities. It requires a great deal of patience and time to warm the cooled room.
In this regard, contemporary aluminum, bimetallic, steel products that heat the surroundings rapidly and provide instantaneous heating outperform cast iron radiators by a wide margin. See which radiators—cast iron or bimetallic—are superior.
They cool just as quickly, I must admit, but the split cast iron warms the room for a very long time after being disconnected from the system.
Cast iron’s thick walls retain heat for a very long time. maintaining a pleasant outside temperature.
What is the cast-iron heating radiator’s single section’s heat transfer? That is 110–160 watts on average. Furthermore, warming the radiator cover directly enables the heating radiation to "reach" and warm various objects in addition to the surrounding air.
As a result, heated nearby objects start to emit heat as well. And after a while, the room starts to get warm.
Expandation of pressure
It is fair to say that cast iron radiators are the most resilient and long-lasting, making them ideal for use in central heating systems. Depending on the modification, working pressure can be as high as 9 atm. The significant thickness of the cast-iron walls is the cause of these elevated indicators.
Coolant
Since drinking water can warm up in a variety of ways, it is technically not appropriate to use as a coolant in cast iron batteries.
It is no secret that even if the water used as coolant in the heating system was initially spotless, it quickly becomes a liquid with an unexplainable origin. Chemical reactions of all kinds explain this. taking place within the battery.
Enhanced Abrasive, alkalis, and sand content encourages active radiator corrosion from the inside out. And if this is the reason why steel, aluminum, and their alloys corrode so rapidly, then the cast-iron battery is nothing.
Iron cast not rust-covered and during the off-season, after the heating systems’ spent coolant has been drained.
On average The coolant used in cast-iron radiators has a temperature of 130 °C. It is also observed that using batteries in solid fuel boilers causes the battery’s inertia to increase. The people who live in the icy northern regions value this quality of cast iron.
The complexity of installation
Prior to independently attaching the radiator for heating. Speaking with an expert is essential.
It is important to remember to follow safety precautions during installation. Turning off the water supply is one of these prerequisites, particularly if the work is done in the middle of the heating season.
It is advised that the heating system be installed before the heating system operates. It follows that you should plan out the installation location and select a radiator design beforehand. For instance, radiators with a single-pipe system are typically installed in apartment buildings. This is because the part is inexpensive and easy to install. For country homes and cottages, two-pipe systems should be installed.
Crucial: when installing a cast-iron heating radiator, the spaces between the battery and the walls, the windowsill and the floor, must be strictly observed. Adherence to fire safety protocols must be maintained.
The steps involved in connecting the apartment’s system in sequence are as follows:
- block heat supply throughout the riser;
- drain the coolant through the riser (these actions are consistent with the local house management);
- After making sure that the system is dehydrated, they dismantle old batteries, followed by replacement with new radiators;
- throw the air with the Maevsky crane;
- Installation of shut -off valves, which allows for repairs and prevention in autonomous mode in the future.
The following is the process to connect the heating system in parallel:
- block valves on shut -off valves (in the absence of such an action described above), replace the radiator;
- check the tightness in the places of connection of the radiator to the pipes;
- With the help of brackets, securely fix the battery;
- With a parallel connection, it is recommended to install a thermostat, with which the volume of the coolant in the radiator is controlled.
Average "Life Life"
Cast-iron heating radiators have a minimum service life of 50 years and can be operated for an exceptionally long period due to their corrosion resistance and high working pressure indicators. This is also because fewer costly and frequent repairs are required.
Advantages compared to other batteries
- An indisputable advantage of a cast -iron radiator over modern aluminum, steel, bimetallic batteries is its durability. Half a century of the anniversary of the cast -iron battery – the phenomenon of the widespread. In some cities, those batteries that cast in the century before last are still preserved and continue to work regularly.
- Cost price cast -iron product can only please the future owner – European prices for over -fashioned aluminum or bimetallic batteries are far from every pocket. In addition, the purchase of a large number of sections promises significant benefits.
- Another dignity of cast iron – lack of any requirements for the coolant. Water of any quality is poured into the heating system.
- The thickness of the cast -iron sections allows you to withstand the most High operating pressure. Starting with 9 atm and above. In addition, cast iron tolerates hydrouches perfectly, so it is he who gives an advantage in centralized heating systems.
Flaws
- The greatest discontent with cast -iron batteries, perhaps, causes them appearance. for many decades. Of course, an old radiator looks wretched in an apartment with an expensive modern repair. But, as you know, there are no comrades to the taste and color of.
Modern cast-iron masterpieces embellished with cast monograms and patterns are available to consumers in addition to traditional models, thanks to the efforts of current manufacturers, including foreign ones. furnished with a broad color palette of ornamental legs. Modernized radiators with a broad variety of sizes and designs are made under the "euro" brand for fans of cast-iron stoves.
These products are not cheap, of course, but only the most discerning consumers of luxury and comfort will find value in them.
- Light weight and dimensions perhaps only a master who has to raise and wear such a severity can upset the cast -iron radiator.
- Long -term heating The thick cast -iron battery has its own advantages: heat is maintained longer in the room, while aluminum and bimetallic cool are cooled as quickly as they heat up.
- Heat transfer of a cast -iron battery is much slower. than radiators from lighter metals. Although aluminum and bimetallic analogues with similar dimensions consume a smaller volume of the coolant, and their heat transfer is one and a half times higher, the design and technological features of the cast-iron radiator significantly increase the useful coefficient of the product.Thermal wave (about 35% of thermal energy), released by hot cast iron, spreads in the lower tier of space, warming it up. Then, according to the laws of physics, heat begins to rise up, warming the remaining 65 % of the air mass.
With confidence, we can draw the following conclusion from the above: this is the best—it’snotalways newfangled. However, after a century and a half of testing, cast iron will not relinquish its positions.
Technical characteristics of cast -iron heating radiators
It makes sense that anything having to do with heating problems always raises a lot of queries and requires thought-out solutions. Since the heating system serves as the "heart" of the house, it should operate as efficiently as possible and like a clock. It is therefore preferable to stop on a more costly and dependable metal, like cast iron, if that is an option.
External design features
Only in factories are cast iron radiators made; primarily, gray cast iron is used for these applications. The radiator is made up of distinct pieces, or "cloves," each of which contains Coolant will flow through a channel that is shaped like an oval or round. There are two and single channel options for sections. After that, the parts are assembled into a single battery, connected, and sealed with heat-resistant gaskets. The number of sections will determine the battery’s size.
Cast iron heating batteries come in a variety of sizes; different models with varying sectional parameters are currently available. Depending on the room’s dimensions, insulation, and the number of windows and doors in the house, each size is chosen separately. Radiators range in size from 35 to 150 centimeters in height and from 50 to 140 centimeters in depth; the width is chosen depending on how many sections there are.
Batteries are made by casting method. Therefore, the design is tight, reliable. Cast iron accumulates and gives heat, suitable for autonomous and central heating systems. Cast iron batteries have high indicator of wear resistance and service life. The pressure of pressure, the working pressure in the battery – nine atmospheres are well withstanding. They are also unpredictable to the coolant, small sand and scale when the hot water movement cannot cause significant damage to the channels inside the sections. For central stamping systems, where the coolant during the journey “acquires” a good supply of chemical elements, cast iron is also suitable, since the metal does not enter the reaction and does not rust.
Technical features of cast -iron radiators
The battery model affects the features of cast-iron heating radiators. There were numerous NM-140 factories, Minsk-110, NM-150, R-90, and RKSh—to name just a few of the species produced—when Chugun had no rivals. The most popular and long-lasting model is the now-preserved MS-140.
The MS-140 boasts remarkable dimensions, including a 140 cm depth, power ranging from 0.12 to 0.16, a section with a coolant volume significantly larger than its analog counterparts (from 1.11 to 1.45 l), and an average weight of 7 kg. The heating surface has a square area of 0.24 meters and operates at 9 atmospheres of pressure.
The batteries have an ugly appearance in spite of all their features. Contemporary models feature more intriguing designs. For instance, the World Cup (G. Cheboksary) has a flat front section that makes maintenance easier and looks good. Radiators with one, two, or three channels are manufactured, and their technical features include the following:
- World Cup-1, compact in depth of 70 cm, power from 0.075 to 0.11 kW, weight of the section on average 4 kg. Working pressure is 9 atmospheres.
- World Cup-2, up to one meter in depth, power from 0.1009 to 0.1423 kW, weight about 6 kg. Optimal pressure – 9 atmospheres.
- World Cup 3, 130 cm deep, power from 0.1083 to 0.1568 kW, weight 7 kg. Working pressure will be 9 atmospheres.
Compact radiators made by MS-110 (Plant Pltekli) fit easily into small spaces and blend in under slender windowsills while maintaining a nearly unaltered appearance.
It appears that foreign companies are leading the way. Because of their extremely smooth surface, cast iron radiators have a high heat transfer capacity and a modern, compact design. These radiators are made in factories in Turkey, China, and the Czech Republic, all of which have established themselves as reputable and high-quality producers in the marketplace. One of the firms’ models did not alter the standard forms; rather, cast patterns were applied as a decorative element.
In contrast, the Konner Modern model’s technical specs are as follows: it weighs only roughly 5 kg, has a working pressure of 12 atmospheres, a depth of only 80 cm, and a power range of 012 to 0.15 kW.
Cast iron radiators are a great option for efficiently and effectively heating your home. These radiators have a reputation for being strong, having a timeless appearance, and holding heat long after the heating system has shut off. Cast iron radiators, in contrast to some other materials, provide off a constant, reliable heat that fills your house with coziness. Because of their sturdy design, they also require little upkeep and have a long lifespan. To accommodate varied tastes and heating requirements, they also come in a variety of sizes and styles. Cast iron radiators are a dependable and classic choice to take into consideration, whether you’re remodeling an older house or replacing your heating system.
What you need to know before buying
Naturally, if cast iron radiators are properly maintained and operated efficiently, their lifespan is practically endless. Long cooling times and, of course, efficient heat transfer make up for prolonged heating. Simple, dependable radiators are easy to use and don’t require a lot of setup or maintenance.
To make the rooms optimally, it is necessary to accurately calculate the desired power: 1 meter in a square of the area is necessary about 120 watts of power, provided that the room has a window opening and one outer wall. When changing conditions, it is better to add the section. For the intra -house system, the temperature of the coolant should be at least 70 degrees, then the number of sections can be reduced. If the area of the room is quite decent, with several windows and poorly insulated, the calculation is best done based on the formula: 10 meters in a square of the area will need 1.3 kW of power.
It is crucial that strong or frequent hydraulic shocks were not applied to cast iron batteries. which can harm centralized systems, causing them to suffer. When taking care of the battery, you should keep an eye on the paint’s condition and either tint it or repaint the entire thing. Prompt medical attention can prolong life. The choice of technical parameters is contingent upon the kind and condition of the heating system. It is preferable for centralized systems to select radiators that satisfy the coolant’s technical specifications and factor in a margin of safety.
Radiators must only be installed on specific brackets. which is able to bear the weight! There are flooring options if there isn’t a way to hang the battery; some models have legs for this purpose. Radiators can have screens placed over them to give an aesthetic appearance.
