How convenient is this option for heating a house? Advantages of aluminum heating radiators

Aluminum radiators stand out among the variety of models due to their beautiful appearance.

They light, durable, elegant, fit well into a modern interior, have a high degree of heat transfer. These radiators heat in two ways: by heat radiation and convection.

Which radiators are better to choose: aluminum or steel

Steel radiators are usually installed at the construction stage of houses. Advantages aluminum batteries have a better performance than steel ones not many, but they are there.

These radiators more reliable, since the working pressure is 16 Bar, and for steel ones - 9. When radiating, aluminum heaters give off about half of the heat, the rest is generated by convection.

Compared to steel when used saves about 20-30% of consumption thermal resource. One more thing advantage - lightness and simplicity of designThis mostly concerns European type radiators.

Aluminum Batteries: What Are They?

When choosing aluminum batteries, look at their design, construction, technical characteristics are checked. And it is also important to know the manufacturer.

Design

The device differs in the type of sections:

• Cast — cast in one piece; resistant to breakage. Highly priced due to manufacturing complexity.
• Extruded — with this method, the sections are first formed, then connected with glue or special nipple nuts. They are not produced in Europe.
• Hybrid — connected by electrochemical welding to collector blocks.

Additional thin ribs inside the section increase heat transfer. Many models are equipped with thermostatic heads for temperature control.

Technical specifications

They have different technical characteristics, for each model they are listed in the technical data sheet. This dimensions; maximum working and test pressure, temperature to which the coolant is heatedThe technical characteristics also include the parameters of the volume of water in the section and the distance between the axles.

Appearance

Section design and wide range of dimensions (depth, height) allow you to select the desired battery configuration.

They can be vertical or horizontal. Aluminum radiators often embody original design solutions and claim to be an interior element.

Pros and cons: are they suitable for a central system?

Advantages:

• light weight;
• high thermal conductivity;
• endure high blood pressure;
• low need for coolant;
• low heat capacity;
• easy installation;
• affordable prices.

Flaws:

• Sensitivity to parameters of the circulating fluidChemical impurities in water and high acidity quickly spoil the radiator from the inside.

• React to strong pressure surges in the system. Water hammer can damage even new batteries.

Algorithm of actions: how to assemble and disassemble

It is not difficult to disassemble an aluminum battery. The main thing is to do the work very carefully, as thin aluminum is easy to damage.

The radiator is disassembled:

• to eliminate leaks;
• when replacing seals;

  

• For removing unnecessary sections;
• at build-up;
• during installation new heating system.

To disassemble and then assemble the battery, you will need a set of the simplest tools. These are radiator and spanner keys, a screwdriver.

Before dismantling, first close the valve. Wait until the water in the radiator cools down. Take a wrench of the right size and unscrew the connection. Remove the battery, drain the waterTo separate the sections, use a radiator key to unscrew the connecting nipple nuts.

To assemble the sections, work is carried out in reverse order.

Power calculation

Calculations are made based on the area of ​​the heated room.

To warm up 1 sq.m. of living space required not less than 100 W of powerA special formula will help you make the calculation: K = S x100/P, in which:

• S — area of ​​the premises in sq. m.
• R — designation of the power of one section, measured in W.
• TO - how many sections will be required.

You can also use a simplified method, it is believed that One section heats 1.8 m². But such a calculation for determining power is fraught with large errors.

Another fundamental parameter for a heating battery is its heat output.

It is wrong to calculate any one parameter. Batteries with additional ribs increase heat transfer.

It is also important to consider number of windows and doors, condition of the walls of the room. For corner rooms, it is better to select more powerful batteries.

What does the heating diagram look like?

There are three connection schemes:

1. Lateral or one-sided: the main pipe is mounted in the upper branch pipe, and the outlet pipe is connected from below. This is the most common option.
2. Diagonal: used for batteries with 14 or more sections. The inlet and outlet are positioned diagonally. On one side, the outlet pipe is installed in the lower branch pipe, on the other side, the feed pipe is installed in the upper branch pipe.
3. Lower: the supply and outlet pipes are installed from below on different sides. Used for heating pipes built into the floor.

In any case, it is better to contact specialists for connection.

Choice

When choosing, focus on the following parameters:

• type, the best option is cast;

  

• technical passport, it contains all the characteristics of the selected model;
• connection system: upper, lower, etc.;
• ask the seller battery test report, which confirms the characteristics stated in the passport;
• check before buying certificates of conformity;
• don't choose a heater because of appearance, if its quality does not meet the required parameters;
• It is advisable to buy from reputable European manufacturers.

Price

The cheapest radiators from Russian manufacturers. According to user reviews, it is better to buy foreign models if you choose by quality, not by price.

One section costs from 270 to 750 RUR According to approximate calculations for an apartment 60 sq. m required 30 aluminum sections.

But not all Chinese radiators are of low quality.

Data in the product passport

The product passport specifies:

• Name goods;
• technical specifications;
• data about certification tests;
• instruction on installation;
• warranty obligations.

Features of use in a private home

Aluminum radiators heat up and cool down quickly. Due to the narrow channels, there is no need to fill the systems with a large amount of water. Aluminum batteries in a private house will work at low pressure and will last for a long time. It is unacceptable to add chemical additives to the water.
