Heating radiators for antifreeze which are suitable
Almost all types of radiators can be installed in the house or apartment, but there are some restrictions.
It is not recommended for apartments: installing steel radiators of panel type, since they have a fairly small working pressure of only 6-8 atm., Whereas in the centralized heating system, the pressure can reach 10 atm., What can lead to collector deformation. Also, in such a system it is not recommended to use aluminum radiators in which galvanic corrosion occurs when interacting with various metals.
In apartments with centralized heating, it is recommended to use bimetallic and cast.Iron radiators, which are most resistant to corrosion and have a long service life.
In private houses, you can use all the radiators without exception of any type, the main thing is to correctly calculate the right power. But there are recommendations.
There are also restrictions on the use of various types of radiators in closed and open heating systems. In systems with forced circulation, you can use all the above radiators, but for systems with natural circulation, only cast.Iron and aluminum batteries are suitable. They have fairly wide connecting holes between the upper and lower collector, which contributes to the uniform warming up of the battery throughout the height.
Types of coolants for aluminum radiators
The most ordinary coolant for the heating system is water, but sometimes it leads to numerous difficulties. This is not only corrosion, but also the formation of scale, the need for a more frequent system cleaning. In addition, water freezes already at a temperature close to zero degrees, pipes and individual elements of the circuit can simply burst with temperature expansion. Therefore, it is important not only to choose the right batteries, but also to use the non.Freezing coolant. Of the advantages, it should be noted full safety for humans. If the system is leaking, then harm to health will not be done, while antifreeze is phenomenon.
Is it possible to mix different types of antifreeze with each other?
Whatever the types of antifreeze are, but it is not desirable to mix them without conducting a check for compatibility. After all, if the main additives of liquids are different, then a precipitate may appear and the anti-corrosion properties will deteriorate due to their destruction. If it is not known exactly what antifreeze was in the system, then before filling the new, it is necessary to completely drain the old.
It is best to use distilled water for these purposes, which contains magnesium and calcium salts. Practice shows that when diluting hard water, there is a high probability of sediment. Water water can be used to dilute, but only if the stiffness does not exceed 5 mg-executive.
You should not consider water from the column the best option, because it will have a lot of rigidity, the value of which can reach 20 mg-explosions. It happens that the determination of stiffness is complicated for one reason or another, then you should previously mix water with antifreeze in the necessary proportion and see if the precipitate will appear.
What should not be forgotten
There are restrictions on the use of any antifreeze as a coolant. Even independently cooked.
It is forbidden to use antifreeze:
- In systems with electrolysis boilers;
- In open systems;
- When the installation of the system is carried out using galvanized elements.
If it is planned to use antifreeze in the heating circuit, experts do not recommend mounting equipment using linen pacle planted on paint. The unipak plumbing kit is perfect for this.
Use at temperatures below.20 O C, (and therefore, in antifreeze it is necessary to increase the percentage of alcohol) leads to the formation of scale in the form of a heavily washed sediment inside the pipes and radiators.
Important! If the planned operating temperature in the circuit is above 70 ° C, then the use of antifreeze is undesirable. Since the high expansion of water provided by alcohol can lead to an emergency.
Professionals recommend planning the system on antifreeze in advance, since such a system has their own nuances: the capacity of the boiler, equipment from certain materials. Its re.Equipment after the use of water as a coolant will cost a little.
If necessary, you can add the carrier only the same brand that was originally used.
Pour antifreeze in the heating contour for aluminum heating radiators, or choose another coolant. The owner of the house will decide. It is simply important to know that this option also has the right to exist.
Materials for the manufacture of radiators for water heating
The most familiar material for people from Soviet times is cast iron. Most of these batteries have completed almost every house and apartment of those times. And in the present, such heating radiators are produced, but these are not standard options, but quite modern, but still. They also weigh a lot.
It is worth noting that cast iron is a fairly fragile material, and the batteries will be afraid of strong blows.
And here we mean not only mechanical blows from outside, but also hydraulic boards. They can also destroy relatively subtle cast iron.
The maximum working pressure for most cast-iron batteries is 10-13 atm. It is worth noting that cast.Iron radiators are relatively often between sections. In this case, it will be better to sort out the battery and change the gaskets to heat.Resistant rubber, the temperature of the water in the heating battery will not affect the integrity of such a gasket.
The next option is a steel water heating radiator. Thermal conductivity of steel is almost the same as in the case of cast iron, but steel radiators are more durable.
Usually a steel radiator has a plate type. This means that two profiled plates are welded along the contour.
Inside the fluid for heating radiators will flow through winding channels. As for the devices of domestic production, in the old years, such radiators worked for only 7 years, and their strength was also low. The pressure limit was 6 atm. In addition, such batteries had low heat transfer. In modernity, especially imported production, makes devices of the same type, but with a good appearance and technical properties.
Also, these devices are designed for pressure from 10 atm. The manufacturer’s warranty is 10 years. The heat transfer indicator depends on the dimensions. Tubular radiators are another subspecies. The principle of design. The upper and lower collectors connect straight and curly pipes along which the heat carrier walks. Such radiators are durable, and very often their high heat transfer is combined with an excellent design.

Radiators are also made of aluminum. Aluminum water heating radiators appeared on the Russian market around the 90s. Such radiators have a pleasant appearance, and their heat transfer will delight even the demanding consumer. In addition, the cost of such radiators is relatively affordable. But, unfortunately, everything is not so beautiful. Centralized heating in our area is not perfect, jumps in pressure can constantly appear here.
Aluminum is strong enough for the batteries to work as usual, but if a force majeure occurs for 25 atmospheres, then the battery may simply fly apart.
Another drawback is that aluminum with some materials forms galvanic couples. This will lead to the appearance of a weak current, as a result of this, the inner surface will collapse faster.
Now we note the mixed types of water heating radiators. This is the compound of aluminum steel. The problems described above were solved using such radiators called bimetallic. The principle is simple. Inside the aluminum membrane, which has a large area of nuting, have a core of steel that is resistant to corrosion. The heat transfer of such a radiator will only be slightly conceded with a whole aluminum.
The stability of such radiators to the pressure is simply different. The norm is 25 atmospheres of the working pressure.
Another combination is aluminum and copper. The basis of such a battery is a round of a thick copper tube. Aluminum nuting is pressed on copper. From above the radiator will protect the steel casing. From mechanical damage. Copper has amazing thermal conductivity, so the fluid for heating batteries will give a lot of heat. Such water batteries for heating the apartment are compact, but give a large amount of heat.
Features of heating in a private house
In suburban houses and cottages, the heating system is usually connected to the boiler and has differences from centralized systems. The most important of them:
Unlike centralized systems. In autonomous. With proper operation of the boiler. The probability of a hydraulic jacket is practically excluded. This feature, as well as the low pressure of the coolant allows you to use almost any types of radiators, without fear of destruction and leaks.
If water is used as a coolant, its quality can also affect the operating conditions of radiators. In particular, hard water with a large amount of salts can cause the formation of sediment on the inner surface of the radiators, and, as a result, to narrow the lumen and the deterioration of heat transfer.
The type of system. Open or closed. Is also important.
In the open system, oxygen dissolved in water is constantly present, which at elevated temperatures leads to quite active corrosion of some types of radiators. In closed systems with a membrane expansion tank, oxygen during the initial heating of the coolant is binded into insoluble compounds. Metals oxides, after which corrosion stops before filling a fresh portion of water.
Also, in private heating systems, antifreezes are sometimes used that do not freeze at minus temperatures. Their use allows you to stop the boiler in winter, which is convenient for suburban cottages and houses used for periodic living. Not all types of radiators can be used in systems with antifreeze.
Which heating batteries to choose for a private house and cottage
It is not difficult to choose a battery for a private house, because the operation of an autonomous heating system occurs without significant overloads, which a centralized system experiences. Here you can connect any radiators, focusing on the necessary capacity, quality, efficiency, cost of the device.
Many owners of private houses prefer aluminum radiators. They are cheaper than cast.Iron, more economical in operation and have higher heat transfer rates, and the sensitivity of aluminum devices to hydrouches in the autonomous heating system can be neglected.
If there is a desire to choose batteries based on the name of the brand, then you can take into account the unspoken rating of aluminum heating radiators for a private house. The top positions here belong to the brands of Calidor, Global, Rifar, STI, which are well suited for operation in Russian climatic conditions.

Steel radiators are no less common, which is not surprising, because they are reliable, affordable, able to warm up quickly and have good heat transfer. Here in the ranking of steel heating radiators for a private house, the leading places are occupied by Kermi, Purmo, Zehnder, Sunerzh.
Among worthy brands producing bimetallic radiators, Russian Rifar and Italian Global can be noted. Those who decided to purchase cast.Iron heater should pay attention to Konner (Russia), Guratec (Germany), Retro Style (Russia).
As a result, all radiators are universal, which means that the question of heating batteries is better for a private house with a gas boiler is not entirely true, because when choosing they are mainly focused on the required power, the features of the premises and the possibilities of the budget.
Briefly about the main thing
The coolant for heating a private house allows you to effectively and safely transfer thermal energy from the heating contour of the boiler to radiators, which in turn give heat to the surrounding space. The coolant must meet the next series of requirements:
- Full heat transfer.
- Chemical inertia.
- The optimal range of operating temperatures.
- Lack of harmful components in the composition.
- Stability and constancy of working parameters.
- Safety for people and the environment.
Water can be used as a coolant. It tolerates heat best, free and affordable. However, it freezes at zero degrees, causes corrosion and can form insoluble salts. Non.Freezing fluids are deprived of such shortcomings.
Antifreezes are divided by chemical composition into. Ethylene glycolial, propylene glycolial, glycerin. There are also special for electrode boilers and mineral. Tosol as a cheap alternative cannot be used. You can pour antifreeze manually and pump. At the same time, control of working characteristics and clear observance of technology is extremely important.
