Aluminum radiators: advantages, disadvantages, types, characteristics

During the construction of a private home it is very important to pay attention to heating radiators, installed in it. The correctness of this choice depends on the heat in your homes. In the market different variations of the heating units. Recently appeared among other aluminum radiators.

Advantages of aluminum radiators

Important quality aluminum - compliance, however similar material radiators economical.

• Low weight. Radiators, on the basis of aluminum is much easier to transport and install than the radiators of the other metals. This is due to ease aluminum. One section in weight does not exceed one and a half kilograms.
• Increased heat. Due to the increased aluminum heat exchanger requires a smaller amount to achieve the desired temperature in the room.
• Excerpt. The heater can withstand the flow temperature of 110 degrees.
• The optimum ratio of price and quality. Produce batteries of a reasonable price of this metal, so the final cost becomes lower than competitors.
• Powder coating. The components included in the paint powder on the basis of less subject to corrosion, so this cooler does not need repainting throughout life.
• Attractive appearance. Aluminum heaters aesthetically pleasing look, so they do not spoil the already-formed interior. In other devices additionally hide section decorative boxes and grilles for beauty.
• The distance between the axles. It is in the range of 350 and 800 mm. Therefore it is easy to select a model appropriate to the required room.
• Volume. One section in the volume capacity of 0.25 - 0.5 liters of coolant.

Minuses

Not suitable for some apartment buildings, or do they need to install additional hardware.

• Insecurity. Sectional battery less reliable, unlike cast, especially if the assembly of parts is done with the help of professionals. Such a device may eventually leak.
• Sensitivity to water. If the acid-base balance of water exceeds 8.7, the aluminum enters into reaction with water. Hydrogen produced during the process can break the radiator. To avoid the sad consequences of the air vent is required.
• Corrosion. Aluminum is corrosion resistant, it occurs at the connection points with the heating designs. To avoid it, some manufacturers have applied to the inner portion of the anticorrosive layer, or chromium is used for the connection adapter.
• Fear of water hammer. Heating device aluminum break from water hammer. To avoid lifters breakthroughs are needed that will provide protection against sudden pressure surges in the heating system and the heat sink mounted uberegut rupture and leakage. The installation of such a device should trust the professionals.

Types of aluminum radiators

Despite the use of the same metal, aluminum radiators differ from each other in the production method. Batteries sold alloy produced by extrusion and anodised type.

Cast aluminum radiators

They are made by casting an in molds. The liquid metal flows into them by injection channels. After crystallization, the form disclosed, and this section removed and allowed to cool. Each section is separately collected so the battery can consist of several components.

For the production of most commonly used silumin - alloy in which, besides aluminum, there are elements of 12% silica additive. Ready heating device maintains pressure at 16 - 20 atmospheres. Channels such large batteries that allow fluid to circulate freely within the system.

extruding

The plant heat exchangers are made by means of the press, in 2 stages. First aluminum profile attached form half section. 2 is manufactured such instance. Then these parts are welded together, forming an integral part.

In contrast to casting, such a radiator can withstand up to 40 atmospheres, depending on the manufacturer and the quality of the assembly. Unlike batteries manufactured by extrusion from casting - in value. The first are cheaper, but they can not be improved during use.

Radiators anodized type

They are made of pre-purified metal. In the manufacturing process the device is subjected to the oxidation process, which alters the structure of alumina. Because of this, these radiators is practically not subject to corrosion.

The plant next heater elements connect couplings, which are mounted externally. Therefore, the internal battery side - smooth. Anodized radiators give off heat better than others. Capable of withstanding pressures up to 70 atmospheres. They are more expensive than other types.

Furthermore the method of production, radiators are divided into even integrity.

prefabricated

This made climato sectional. In this way the final product is adjustable length. At the customer's request, it can make a room. The heater must not exceed 70% of the length of the window opening, under which it is installed. Sections are connected is already in place.

whole

Made directly integral unit on existing standards. Precedence over sectional - price as for production uses less metal.

they are not always suitable for building custom sizes as well as an indicator of heat is higher or lower than required. Because of this, the room can get warm enough.

Characteristics of aluminum radiators

• The distance between the axes of climate equipment. This is the length from the center to the upper middle of the lower reservoir (pipes in the heater). Standard - size 200-500 mm.
• Working (10-15 atmospheres) and the test pressure (20-30 atmospheres). The first maintains the battery in the operation, and the second - during pressing. There is a possibility of poor break heater during such tests.

Payment

for sectional

If the required room non-standard sizes, it is best to choose a sectional heating device. The number of segments needed to calculate that there was no extra cost, or lack of heat.

By volume. It is made in the following sequence:

1. Determination of heat demand according to the norms. According to the building regulations, the amount of heat required for the room, still 41 watts per cubic meter, but these calculations are building insulation. If the building is poorly insulated, then you need to increase the figure to 50 W / m3. If the walls of the room there is a layer of insulation, and even installed plastic windows - rate is reduced to 30 - 34 W / m3.
2. Calculate the required number of sections. The first step is calculating the amount of space that needs heaters.
3. Let us assume for example room width of 4 m, 5 m and 3 m high ceiling. Multiplying values ​​and obtain a volume of 60 m3.
4. Determining the heat demand for apartments. Flat - middle without additional insulation layer. The value for it is approaching 41 W / m3. Multiply the figure with the volume of the room, the result is 2460 watts. This amount of energy is necessary to provide heat to your room.
5. Pay attention to the amount of heat generated by one section of the battery you choose. Modern power samples give in the following range - 80-212 watts. Take for calculating an average value of 170 watts. The amount of heat required is divided by this value, and then the sum is rounded up. We get 15. That is the number of sections it is necessary to heat the above premises.

There is also a more simple way, it is used for areas where ceilings - 2.6 meters.

Calculation of the area. In such a calculation requires only the length of the room's walls. Consider the example of the room, similar to the previous but the ceilings there are at least 2.6 meters. When this calculation is taken need to 100 W / m3, regardless of conditions.

1. We calculate the area of ​​the premises. It is 20 m2.
2. Determination of the amount of heat required for heating. Multiply the demand for area, eventually coming out 2000 Watts.
3. Now you need to find out which emissivity has a battery section. As in the previous calculation, take value of 170 watts. It shares the need space, and the result is rounded. According to the calculations we have found that for the room shown in the example, 12 units are required.

for the whole

Calculation for the whole heat batteries is different from the phase section to calculate the heat quantity necessary room. If the previous example, you divide this value by the heat transfer section, here you compare heat indicators. Needed for the premises and the one that matches your chosen radiator.

If the number of watts produced by the battery below, you must install an additional climatic device which allows to cross the lack of the necessary heat.

installation

At room whose area exceeds 25 m2, two batteries are necessary. This means that the resulting number should be divided by two. Since heat is evenly distributed.

When calculations applicable standard temperature of the liquid circulating in the batteries. It does not exceed 70 degrees. If the temperature is above this figure, the end result is reduced by 15%.

There are a number of correction factors, which will help more accurately determine the number of sections. They are added to or deducted from the amount of heat required cubic / square per meter:

• Using standard windows or inadequate insulation, the number increases by 1.27 watts.
• Installed additional layers or insulating glazing allow subtracted from the amount of heat of 0.8 watts.

Aluminum radiators, in spite of the shortcomings, are popular among the population of our country, especially the owners of private houses. If you get them, remember a few rules:

• Learn the pressure in your heating system. This will help you decide which way to be manufactured radiator is suitable for your home.
• Measure the distance between the axes for a more precise selection.
• Calculate the required number of sections that provide a good level of heat transfer.
• Take care of additional safety and find the necessary instruments to reduce risks, and set the thermostat for greater comfort.
• Entrust the work to install a heater to professionals who know their business and can provide you with a guarantee of quality of the work performed.

By following these rules, you will be able to choose a quality heater that is suitable for your space. Customers choose aluminum radiators because of the attractive price, so you should look at it.
