Radiators , aluminum : modern choice

Types of aluminum radiators heating

in urban multi-storey buildings with a central system of water heating radiators selection is carried out at the stage of design and construction, and preference is given to the radiators of steel.Owners of private buildings country, establish an autonomous electric boiler for heating his home, increasingly prefer aluminum radiators heating, and have good reason to.

The first group may include a battery made of silumin.This metal alloy additives and siliceous constituting up to 12% by volume, can significantly increase the strength of the heat transfer surface.The second heaters are anodized type.Consider their design and specifications.

• cast aluminum radiators.Manufactured by molding of individual sections of the device under high pressure silumin in flasks of different shapes and assembled into a block by means of threaded connections and internal paronitovye (or silicone) liners.
• extrusion option .aluminum radiator sections are assembled from individual parts (usually three) are fastened between screws.The assembly is seated on the cast manifold of silumin alloy and subjected to further dismantle not.Add a new section to remove unnecessary or fail.
• Devices of anodized metal.Expensive way to combat corrosion by anodic oxidation of the shell material.To mount the heat transfer device such compounds are not used the usual nipple and special couplings, respectively at times increases price of the final product.

Which aluminum radiators

better question is not idle, and before you decide to purchase, please note the following specifications of the radiator.

• operating pressure - this figure is usually specified in the device data sheet and determines the possibility of its use in the central heating system;acceptable value -15-16 atmospheres;
• test pressure - maximum tolerance of water hammer, which is in the network connection point may be 25-30 atm;
• dimensions : the battery is necessary to enter into the interior of the room, then, its depth and height are of paramount importance to you;for that there is a value center distance;
• heat : all the characteristics of a section greater than 150 W can be considered quite acceptable, but it is better to look for the device 180;
• design and material : this question we have already discussed above, but any comments on best design is not allowed.

Believe aluminum radiator price consists of these terms and to date (November 2014) is in the range (sampling of reviews of buyers in St. Petersburg, price per section):

• Varmega (191 kW heat output, the width of -80weight - 1.2 kg, working pressure of -15 atm) - 270 rubles.
• EleganceWAVE (176/87 / 1.4 / 16) - 464 rubles.

As you can see, the spread in prices for aluminum radiators with similar parameters, but from different manufacturers, is wide enough, so you have to choose your on additional criteria. FAQ : the average price of heating devices Economy class aluminum to heat the room area of ​​19 square meters (sections 10-11) now stands at 3900-4100 rubles.

Advantages and disadvantages of aluminum radiators

Let's start with the positive assessments on customers reviews.

• Thermal conductivity .Aluminium for this indicator is nearly five times higher than other materials for radiators, so the steel and cast iron radiators are less efficient at the same parameters of coolant.Warms better, and almost half are convective heat transfer;
• Weight and dimensions .In the first component of a definite gain in the second - almost full parity with competitors;
• installation and the ability to adjust .Aluminium radiators in this respect the undoubted market leader, especially in the private low-rise buildings with an autonomous heating system.With an operating pressure of 6-10 atmospheres, they work well for 15-20 years.

Negative is the result of design and material.Firstly, the low pressure opressovachnoe.Sectional heatsink extrusion type can simply break during city testing of thermal networks.Second, poor corrosion resistance.With all the technological innovations of the service life of the heat of these devices is unlikely to exceed 20 years.But for country houses such an autonomous heating system is a boon not only for ease of installation, but also the price.
