Aluminum radiators have such advantages as light weight, high rates of heat transfer and a wide range of designs. Manufactured by different technologies models behave differently, being connected to the heating system. In addition, they are sensitive to the quality of the coolant, and most of them are designed for installation in private homes. But with new technologies and the latter do not go unheeded. Aluminum radiators are able to surpass in some respects cast iron, steel and even bimetallic options. The case for small - to competently approach to their choice.

How to choose an aluminum radiator
Different models of radiators made of aluminum alloys, may differ each other not only in appearance but also performance. For this reason enough to pay attention when choosing solely on the design, which, incidentally, in the heat exchange matters. To purchase aluminum radiator should take into account the following options.
Types of aluminum radiators
In the free market, you can find several types of radiatorsWhich differ both manufacturing technology and characteristics, and as a consequence - value:
- Anodized - aluminum is used in the production of high purity (up to 99%), which as a result is subjected to anodic oxidation. The finished article is resistant to corrosion. Anodized model can withstand pressures up to 220 bar, which is much higher than other aluminum options, characterized by high heat transfer, but due to the extremely high costs are not claimed in the market.
- Extrusion (extruded) - created by extrusion of separate parts which are then joined into a finished product by gluing or welding. Due to ease of manufacture and the presence of weaknesses connection technology the cost is low.
- Alloy - it used in the production of aluminum alloy and silicon, and manufacturing takes place by injection molding. Cast solid section, themselves radiators They have an affordable cost and are considered to be the most popular. Chinese version cheaper than European, but lose the quality of both the raw material and a protective coating. In contrast to the same "Italians", after a few years of starting to rust.
Also, there are aluminum radiators and whole teams. The first are the most popular have been recruited by the manufacturer of a number of prefabricated sections (4 to 12 units), depending on the wishes of the client. Also, they can score yourself using special seals. Whole radiators due to the specifics of the design operated in the home is extremely rare.
The pH range
Parameter specifies the recommended manufacturer of acid-alkaline balance of the coolant:
- 7 to 8 - for extrusion models.
- From 5 to 10 - for the variants with special coating of the inner walls.
- 6.5 to 9 - for cast radiators.
If the battery is connected to a private heating, the pH of the indicator need not worry, as the owner of your own picks coolant up to the distilled water. Before you buy radiator in an apartment, do not be amiss to ask about the quality of the water management company or else take a sample and analyze in near laboratory alone.
Height
The total height of the radiator depends on the distance between the centers, ie the distance between the axes of the horizontal collectors. Height is selected based solely on the installation site and on the position of the pipe connection. Most models spacing of 150-800 mm.
Thermal power
This parameter defines the area of the premises, which is able to warm up the battery. Manufacturers indicate the thermal power of one section. To determine the total power must be multiplied by a heat transfer section, and is 150-210 W, to their number. To accurately counting a desired heat output for a particular room complicated calculations are performed based on the number and type of windows, doors and other data.
Pressure and temperature
Manufacturers of aluminum radiators indicate the following important characteristics in the production of passport data:
- Operating pressure - is usually 16-20 atmospheres, indicating the optimum pressure coolant.
- Test pressure - created before the heating season to check on the performance of the system. Of 24-30 atmospheres.
- Reserve mechanical strength - minimum pressure at which the seal failure of the product. Most often it is from 48 to 100 atmospheres.
- The maximum operating temperature of the coolant - is on average at least 110 ° C. Some models support up to 135 ° C.
connection
Depending on the connection of the pipes of the heating system space, aluminum radiators are divided into the following groups:
- On the bottom connection - most of them are set in various state, municipal buildings, shopping and entertainment centers, homes. here tubes suited to the battery perpendicularly to the bottom.
- With side connection - options that would fulfill two-way and one-way connection for by the presence of the four holes at the sides, two of which are unused simply closed plugs. Mounted in standard apartments, especially for the replacement of the old version.
The cross section of the channels
Another important parameter to which you should pay attention - the internal section of the vertical channels. It is:
- Cylindrical - has the highest strength.
- Elliptical - strength slightly lower, but still at a sufficient level.
- Rhomboidal - practically not used because of the low strength characteristics.
What is important is the internal volume of the radiator section. For heating company in a private home, where the low-power applied pumps and reduced total amount of coolant, are selected pattern with a small capacity.
Best cast aluminum radiator
Italian radiator Global ISEO 500 10 sections considered one of the best one produced by injection molding technology. The development of this model was conducted taking into account the Russian climatic conditions, and therefore can be observed fairly high heat transfer performance. The manufacturer gives 10-year warranty on these radiators, Which is not surprising, because in addition to high quality raw materials used in the manufacture of a two-stage method of painting. Product Operation provides for the pressure in the heating system is not higher than 16 bar, which may not seem like the highest value, but it is enough for a private house or apartment.
