A home can be called cozy, in which, even in the winter cold, it is warm and comfortable. Therefore, property owners do not spare funds to create an optimal microclimate using a heating system, the functionality and efficiency of which depends on high-quality and correctly selected radiators.

Modern hardware stores offer a wide selection of different radiators, while the range of heating devices is constantly expanding and supplemented with new models. If a few decades ago, most houses and apartments were equipped with bulky, heavy cast-iron batteries that have an unattractive appearance, today property owners can buy innovative bimetallic radiators with bottom piping and other connection schemes to the pipeline.

When choosing which bimetallic radiators will best complement the heating system at home, it is important to pay attention to their performance and design features, because each model has its own advantages and disadvantages, which the consumer needs to know about before placing an order. Having information about the similarities and differences of models, as well as analyzing the prices for bimetallic heating batteries, the buyer will be able to choose heating devices for his home as correctly as possible.

It is quite difficult for a common man in the street to distinguish in appearance the innovative Syrah bimetallic radiators from ordinary aluminum batteries, the only nuance that will allow you to correctly navigate in a construction equipment store is the weight of the devices. So, a bimetallic radiator is one and a half times heavier than an aluminum analogue. This difference in weight is due to design features.

Universal technical characteristics allow real estate owners to buy a bimetallic radiator for heating private houses, offices, city apartments and apartments in high-rise buildings. They are superior to analogs made of cast iron, aluminum, steel, because in the development process, manufacturers have tried to combine all the available technological advances in bimetallic structures. In the end, the batteries turned out to be aesthetic, lightweight and compact, they are distinguished from a number of analogues by a simple installation process, while the prices are in an acceptable price range for most consumers.

The name of the batteries indicates that manufacturers use two types of metals to make devices. In particular, Italy supplies modern bimetallic radiators to the market in the form of heating devices made using steel and aluminum. Steel is used as the material for the core and the outer casing of the batteries is coated with aluminum.

Thus, inside the steel structure of the battery, a coolant circulates under a certain pressure, while the attractive aluminum case does not spoil the interior with its appearance and allows you to quickly transfer the temperature to the room. The excellent physical properties of aluminum allow the battery case to warm up as quickly as possible. In this case, the basis of the design of the radiator is a steel core, which protects the aluminum shell from the action of alkali, acids and other aggressive impurities present in the coolant.

When choosing which bimetallic heating radiators are better, it is worth focusing on the fact that the steel core allows the heating device to be used even in systems with high internal pressure. Therefore, such batteries can be used in modern multi-storey buildings, where pressure is deliberately injected with the help to supply hot coolant to the outer floors.

Another design feature that is worth paying attention to when studying the prices of bimetallic heating radiators is the diameter of the internal channels in the steel core. The smaller the channel diameter in bimetallic heating devices, the smaller the volume of the circulating heat carrier must be present in the heating system.

Thus, by choosing the best option for batteries, the homeowner can reduce the volume of the circulating coolant by two or three times. This will not only save water in the process of filling and replenishing the heating system, but will also make it possible to instantly warm up the radiators, which among their analogues are distinguished by the greatest sensitivity to changing the thermostat settings.

Production technology of various models of bimetal radiators

The rather high cost of the devices, which fully pays off in reliability, exceptional quality and durability, is due to the technological complexity of the production of batteries. So in the production process, making bimetallic radiators Global, etc., manufacturers can use two design options.

In the first case, the radiators are made on the basis of a steel frame, while the contact of aluminum with the coolant is completely excluded. This design protects the aluminum body of the batteries from corrosion damage and guarantees a long service life of devices in the heating system.

The second option involves the manufacture of aluminum batteries, the structure of which is reinforced with internal steel pipes. Such products are called "pseudo-bimetallic batteries". They differ at an affordable price, but due to the peculiarities of fixing the internal steel pipes, they do not have the reliability and durability of full-fledged bimetallic radiators.

Therefore, before choosing bimetallic heating radiators, it is worthwhile to study manufacturers who use the first option for producing batteries in their work. Full-fledged bimetallic radiators, although they are distinguished by a higher price, have qualitative superiorities over inexpensive counterparts and will delight home owners with serviceable and long-term service in the heating system of the house.

What is bimetal: applications

Bimetal is a material consisting of several layers of various alloys. For heating radiators, steel structures are used that can withstand water hammer with aluminum spraying. The outer layer provides good heat dissipation. Aluminum radiators with a copper core are also used.

Useful information! Bimetal is used in various industries where it is necessary to combine the characteristics of two or more alloys. This increases the durability and reliability of components and assemblies.

The manufacturer offers a wide range of the following materials:

• corrosion-resistant;
• antifriction;
• electrical (conductors, contacts);
• instrumental;
• wear-resistant;
• thermobimetals.

Technical characteristics of bimetallic heating radiators

Modern radiators are produced in two versions - bimetallic and semi-metallic. The difference of the second type is in the contact of the coolant with aluminum - only the vertical channels are reinforced with steel.

In our publication, we will consider not only the types of devices, the criteria for making the right choice, but also popular manufacturers, models, and useful advice from experts.

Good to know! The main parameter that the consumer pays attention to is the thermal power of the metal, measured in watts. For bimetallic radiators, when heated to + 70˚C, this parameter will be 170 ÷ 190 W, which, according to professional heat power engineers, is a high indicator.

The level of permissible pressure in the system is indicated by the manufacturer in the technical documentation of the radiator. Bimetallic heating batteries withstand 16 ÷ 35 atm. (depending on the model). This is despite the fact that this indicator in the systems of apartment buildings is 14 atm., And autonomous heating is "satisfied" with a maximum of 10 atm.

Important! The upper heating point of such products does not exceed + 110˚С. Sometimes the manufacturer in the documentation indicates a threshold of + 135 ÷ 140˚С. This is not worth believing, there are no such bimetal radiators.

The best bimetallic heating radiators for an apartment: advantages and disadvantages

The bimetal has enough advantages. Let's note the main ones:

• durability. The service life reaches 20 years;
• small channel cross-section provides a quick response to thermostat commands at a lower cost of the coolant;
• resistance to pressure surges. Withstand a short-term increase in pressure of 40 atm;
• corrosion resistance, the possibility of operation with a coolant of any chemical composition.

For the disadvantages, we note only the high cost (in comparison with aluminum) and weight.

Types of connection of bimetallic heating radiators

The choice of the type of heater connection depends on the options for supplying highways to them. A distinction is made between devices with side and bottom connection. In turn, the lateral connection is divided into diagonal, saddle and one-sided. Let us examine in detail how the various inclusion of equipment in the circuit is performed.

Bottom connection for heating medium heaters

When installing such a circuit, the lines are brought into the heater from below, there are no questions about connecting. Left branch pipe - supply, right - return. It happens that the manufacturer changes the direction of the flow of the coolant. Then information about this will be indicated on the packaging and in the technical documentation of a bimetallic heating radiator with a bottom connection.

Side connection of heaters: installation nuances

There are three connection options. Let's start with the diagonal one.

This option is suitable if the supply pipe is located above the return. Professional heat power engineers consider this method to be the most effective - this is how heating radiators are tested in production, which means that the technical parameters specified in the technical documentation will be 100% disclosed. In this case, the heated coolant does not encounter obstacles in its path, moving from top to bottom, which allows the use of heat transfer without losses.

One-sided connection of a heating radiator is carried out according to the same principle, but the supply and return are not located on different sides of the heating device, but on one side. This method of connection is used in apartment buildings, where the heating riser runs from one side of the heater. Heat loss in this case will be 2 ÷ 3%, which is not much. But this applies only to radiators shorter than ten sections. In the case of installing long structures, the far part of them will heat up less.

The saddle connection implies the input and return of the coolant on different sides, but at the bottom of the heater. This method is the most ineffective and assumes a heat loss of 14-18%. With this connection option, the number of sections should be increased so that heat loss is not noticeable. The rest of the disadvantages of this installation are not observed. The positive side is the ability to hide the highways under the floor - they are almost invisible on the radiators from below.

Do you want to know which solution is better to choose, is it possible to make antifreeze yourself, a type of non-freezing liquid? Read our publication.

The choice of bimetallic heaters for heating circuits with a coolant depends on several factors, the main of which is technical characteristics. However, the importance of appearance should not be underestimated. These structures should fit into the interior and if not improve it, then definitely not spoil it, as it was with the old cast iron products. They had to be hidden behind decorative wooden battens, which trapped heat.

Now let's figure out the technical characteristics. Let's start with the number of sections required to heat the selected room.

Calculation of sections of bimetallic heating radiators by the area of ​​the room

The question of how to calculate the number of sections of bimetallic heating radiators worries every home craftsman planning to replace the installed or initial installation of heaters. The calculations for this parameter are not difficult. The average power of one bimetallic section is 150 ÷ ​​180 W. Heating 10 m² requires 1 kW (1000 W) of power. Making simple calculations, we get the need for installation in a room with an area of ​​15 m 2 - 1.5 kW or 9 ÷ 10 sections. It can be either one heating point, or two 5 sections each, or 3 to 3 sections - at the discretion of the home craftsman or based on the supply of highways.

For the convenience of our readers, we have developed a convenient calculator for calculating the required number of sections.
