Bimetallic radiator - general information

The most practical choice for rooms of different sizes and purposes is bimetallic radiators. The devices are constructed of steel and aluminum. The radiator has high heat transfer, while being resistant to corrosion processes, reliable and practical.

Bimetallic radiator has the advantages of two metals

The following types of bimetallic radiators are distinguished:

full bimetallic - produced using the casting method, the advantage of the design is that the likelihood of metal contact with the coolant is eliminated, withstands heating up to +130 degrees , pressure up to 35 bar ;

part-bimetallic - in the design of a steel exclusively water-conducting channel, the issue of excess pressure is thus resolved, but the threat of the spread of corrosion remains.

Advantages:

strength;
versatility;
high heat transfer;
simple installation;
exact parameters;
the design is not hazardous;
it is possible to install the valves necessary to control the temperature;
long period of operation.

Pay attention to the material the tubes are made of - they must be steel

What characteristics should you pay attention to when choosing a bimetallic radiator?

Keep in mind! When choosing a bimetallic radiator, you need to pay special attention to the following parameters:

Brand. Reliable manufacturers provide a guarantee for their products for up to 25 years. This will help to replace the radiator, even if it fails after 10-15 years.
Heated area. How many sections should be purchased depends on the square footage of the room. For an accurate calculation, you need to know the power of the unit.
Price. In this case, it is better to give preference to the “golden mean”. You also need to take into account the number of sections. The convenient thing is that you can buy not a ready-made kit, but section by section.

What you need to know about the types of bimetallic batteries

At first glance, bimetallic radiators seem the same, but these designs are classified according to different criteria.

Bimetallic and semi-bimetallic

In bimetallic structures, the outer casing is made of aluminum, and stainless steel and copper are used for the convector core.
In accordance with the technology, a sealed product of high strength is obtained, with maximum protection against leaks. In semi-bimetallic models, the internal frame is made of several metals - stainless steel, aluminum. This design is less durable than a bimetallic one; corrosion processes and leaks are likely.

Artyom Ivanov

Plumber, author of the channel “Good-natured Plumber”

Externally, bimetallic and semi-bimetallic radiators are practically the same. To understand which radiator is in front of you, pay attention to its lower part. For a semi-bimetallic one, there will be specific oval plugs located there. But a completely bimetallic one does not have this.

Sectional radiators

Each section is attached using nipples, thus forming a radiator of the required power.
Pipe sections located horizontally have multi-directional threads. Stacked designs are practical; they allow you to adjust the power by adding or subtracting sections. Such designs also have disadvantages First of all, these are joints; the permissible operating pressure readings are limited.

A significant drawback of stacked radiators is that coolant gets on the aluminum in the event of a leak, resulting in corrosion, and the structure requires replacement faster.

Monolithic radiators

Solid, cast batteries do not have the disadvantages of stacked structures; they are designed for pressures of up to 100 atmospheres , but there is no ability to regulate the power and the price of such structures is on average 30% higher . The main area of use is high-rise buildings where there is high pressure in the heating system.

No. 7 – BR1-500

Price: 2,400 rubles

Our top bimetallic heating radiators for apartments continues. This solution is worth taking a closer look at for everyone who has small children and animals at home. The fact is that it has smoothed edges, making it impossible to get hurt on them. The frame is completely made of reliable and durable steel. In the reviews, owners report that over the years of operation there are no complaints about the model. Heat transfer does not deteriorate, and there are no other problems.

This is due to the fact that the coolant does not come into contact with the inner layer due to its unique design, so it is not subject to corrosion and withstands pressure drops well. High-tech intersection connection using non-flat silicone gaskets, in turn, reduces the risk of leaks to a minimum. According to experts and users, there are no significant shortcomings.

BR1-500

Which radiators are better

1. Cast iron radiators.

Modern cast iron batteries look much more attractive, more compact and elegant in comparison with outdated, Soviet models.

Advantages - durability, resistance to corrosion processes.

Disadvantages : heavy weight, slow heating.

Important! The main cause of failure is clogging with sediment. It is recommended to soften the water or use antifreeze.

2. Aluminum radiators.

They have high heat transfer, are lightweight, quite attractive, and are easy and quick to install. There are assembled structures of 10 sections , or select the required number of sections yourself.

Advantages : aluminum heats up and cools down quickly, affordable price, compatibility with different heating systems.

If we talk about the disadvantages - it cannot be used in systems where it is difficult to control the coolant; aluminum is not compatible with noble metals.

Important! Plastic pipes are used with aluminum batteries, and grounding is also organized.

3. Steel, panel radiators.

This option is most popular for installation in cottages, but steel batteries are not suitable for multi-storey buildings due to the low operating pressure.

Steel radiators have a fairly long service life, are easy to install, have different mounting options, and offer a wide range of radiator sizes.

The main disadvantage is susceptibility to corrosive processes.

4. Bimetallic radiators.

An optimized, improved analogue of aluminum batteries with one difference - a steel distribution tube is installed inside. The design can withstand pressures of more than 35 atmospheres .

Bimetal does not have many disadvantages

Artyom Ivanov

Plumber, author of the channel “Good-natured Plumber”

Before buying a radiator, be sure to find out the level of acid-base balance of the coolant in the house. If the pH is between 7 and 8.5, then an aluminum radiator must be installed in the system. And if the pH is in the range from 7 to 9.5, then choose bimetallic. Only after this can you begin to select a manufacturer.

Connection methods

Side method . The pipe through which hot water is supplied is attached to the upper pipe, the return pipe to the lower one. The pipe is located on one side of the radiator. This connection method is only effective for a battery consisting of 15 sections .

Diagonal method . The coolant pipe is mounted on top on one side of the radiator, the return pipe is mounted on the bottom on the opposite side. The coolant is evenly distributed throughout the battery, ensuring high efficiency.

The bottom connection is used when pipes need to be hidden so that they do not spoil the interior. In this case, efficiency is reduced by 20% .

Only a competent choice of radiator guarantees comfort in the room and rapid heating of the air.

Appendix: How to independently calculate the number of sections of a bimetallic radiator

So, if there is clarity about the rating of manufacturers, then you can choose the model you like. But this will definitely raise the question - how many sections will be necessary and sufficient to heat a particular room?

The often practiced method of calculation, based on 100 W of thermal energy per square meter of area, is not accurate - each of the rooms has its own characteristics, which also need to be taken into account. Therefore, we will take the liberty of offering the reader a more accurate algorithm, which is implemented in the program of the calculator located below.

Necessary comments on the calculation program

A few brief explanations on the calculations:

The total amount of heat loss is affected by the presence and number of walls in contact with the street, as well as their location on the cardinal points and in relation to the prevailing winter winds. The program provides appropriate fields for entering this data.
The climatic features of the region will be taken into account when indicating minimum winter temperatures. In this case, you should indicate not abnormal, but quite normal frosts for your region in the coldest decade of winter.
The wall insulation parameter may raise questions. Here it is better to approach from the position that a wall is considered fully insulated if its thermal insulation was carried out in full on the basis of completed thermal calculations. There should be no uninsulated walls in residential buildings at all - no heating with this approach simply will not help: the room will still be cold, and the walls will be damp.
The characteristics of the room, that is, its height and proximity below and above, directly affect the required amount of thermal energy to warm up the volume of the room and replenish heat loss through the ceilings.
After entering the window parameters, the program will calculate the percentage of glazing (from the area of the room) and enter the appropriate correction factor. A similar approach is used if there are regularly opened doors to the street or an unheated balcony.
Finally, the overall heat transfer from heating radiators is significantly influenced by the scheme of their connection to the circuit and the features of their location on the wall. All this is taken into account by the calculation algorithm.
Attention! The program is capable of producing two total values.

— If you choose a calculation for a non-separable radiator model, then you should take into account the result “A” - this is the required total radiator power for a given room, expressed in kilowatts.

Prices for popular bimetallic heating radiators

— If the goal is to calculate the number of sections of a collapsible radiator, then after selecting this path an additional field will appear in which you must enter the nameplate power of one section of the selected model (in watts). The result is taken from point “B” - this is the required number of sections, rounded up to the nearest whole number.

The model can withstand a maximum pressure of 30 bar, which allows you not to be afraid of large changes.

Steel or bimetallic – what to choose?

Steel radiators are not suitable for installation in apartment buildings. They are distinguished by their attractive appearance and resistance to corrosion, but are very sensitive to pressure. Working pressure ranges from 6-16 atmospheres.

Frequent water hammer in the system will damage the radiator and it will begin to leak.

Taking these features into account, steel radiators are recommended to be installed in private houses or apartments with autonomous heating.

In all other cases, it is better to give preference to the bimetallic model.

Bimetallic radiator Tenrad BM

Cast iron or bimetallic – which one to choose?

In the past, cast iron batteries were considered the only possible option for heating apartments and houses.

But now they are losing to bimetallic devices in almost all respects.

Firstly, such devices are very heavy, so it is unlikely that you will be able to install them yourself.

Secondly, these radiators can hardly be called attractive in appearance, although there are expensive designer products on the market, decorated with forged elements.

But at the same time, cast iron batteries are distinguished by a very long service life, the ability to withstand severe pressure changes and resistance to corrosion.

But, in comparison with bimetallic devices, cast iron batteries lose in terms of thermal conductivity.

They take a very long time to reach temperature, so it takes a lot of time to warm up the room.

In addition, they do not have a regulator, and the user will not be able to independently set the desired temperature in the room.
