Batteries in a country house. Batteries for heating a private house, which is better. Type of heating system

The radiator is a necessary link in the heating system of a private house. This device is responsible for the warmth and comfort in the room. Homeowners often have a question about which heating radiators are best for a private house. Here it is necessary to take into account not only the cost and appearance, but also the technical indicators of the product. If the properties declared by the manufacturer do not correspond to the characteristics of a particular heating system, then rapid wear of the radiator and even its failure is inevitable.

Advantages and disadvantages of different types of radiators

Proven cast iron batteries

The first cast iron radiators were used in heating systems even before the October Revolution. Their reliability, durability, resistance to corrosion are due to the significant thickness of the walls and the inertness of cast iron to aggressive environments. Batteries are not afraid of water hammer, hard water with impurities, critical pressure drops.

Each section of the radiator is made separately by casting. The finished elements are interconnected using threaded nipples, resulting in a cast-iron battery familiar to everyone. Such "accordions" go on sale unpainted.

Interesting! The main disadvantage of cast iron products has always been considered external unpresentability. But some enterprises began to master the production of exquisite retro-style cast iron radiators - decorated with monograms, with bronze and copper patina. These batteries are ideal for a classic interior.

Cast iron retro wonder

The considerable weight of the products can also be attributed to the minuses - one section weighs an average of 6 kg. However, heavy cast iron will thoroughly warm the room, and in the event of an accident, it will give off heat for a long time. The service life of cast iron products is 50 years or more, and their prices remain within reasonable limits.

Pros and cons of aluminum radiators

To be precise, batteries are made from silumin, an alloy of aluminum and silicon. Structures are divided into two types - extruded and cast. The latter consist of separate sections, like cast iron. If desired, the battery can be repaired, reconstructed.

The rigor and simplicity of aluminum molds

Extrusion involves the manufacture of separate vertical blocks, which are connected by pressing. This method is more economical, but it is not possible to add or remove sections from the radiator.

Important! Non-freezing liquid cannot be poured into aluminum batteries - the probability is too high that the metal will react with it.

Advantages of aluminum heaters:

High heat transfer inherent in aluminum and its alloys. Rapid heating of the batteries and, as a result, the premises.
Ability to adjust the heat transfer parameters.
Light weight and compact.
Modern design.

Attention! During operation, hydrogen accumulates in aluminum radiators, which is regularly bled through special air vents. Failure to do so may result in battery failure.

Flaws:

The active reaction of the metal to the acidic and alkaline environment.
Rapid corrosion of a radiator connected to pipes made of another metal.
Possible leaks at the joints of the sections.
Uneven heating: the main part of the heat is concentrated on the fins of the battery.
Manufacturers of aluminum radiators usually give a 10-20 year warranty. This does not mean that after this period it is necessary to dismantle the devices and carry them to a landfill. It is only necessary to periodically inspect the batteries for suspicious defects.

Practical steel batteries

There are two types of steel batteries - panel and tubular. The best heating radiators for the home are panel. The basis of the product is two sheets of steel welded together. Channels for the circulation of the coolant are mounted inside. U-shaped metal plates are attached to them, transferring heat to the room. The thickness of the steel reaches 2 mm. The whole structure is enclosed in a decorative metal box.

Important! Do not leave the system without coolant for more than 10-12 days. Oxidation processes begin inside the battery, causing severe corrosion of unprotected steel.

Elegant steel radiator profile

A large radiator area (from 300x400 mm to 900x3000 mm) contributes to efficient heat transfer, which makes the devices highly profitable. To increase their service life, the pressure in the system should not exceed 8 atmospheres, and the acidity of the water should not exceed 8-9 pH.

Reliable bimetal radiators

This type of battery is designed specifically for central heating systems. In fact, they are steel radiators cast in an aluminum shell. The steel is in contact with the coolant, and the aluminum layer ensures rapid heat transfer to the room.

Attention! When buying, you should choose heaters with a pressure margin if the house is connected to central heating. For an autonomous system, 15 atmospheres is enough, for a centralized system - 30 atmospheres.

Resistant bimetal radiators

The bimetallic radiator successfully withstands hydraulic and mechanical shocks, a pressure of 40 atmospheres, and is undemanding to the chemical composition of water. The use of bimetal in a private house with autonomous heating is impractical, since such radiators were originally created to work in adverse conditions of domestic heating systems.

Water and copper pipes

The structures are made from seamless copper pipe with a diameter of 28 mm, passed through copper fins. Other metals are not used. The main advantage of the product is the rapid heating of the room. The thermal conductivity of copper is two times higher than aluminum, and 5-6 times higher than cast iron and steel.

Elite copper radiator

A small amount of water is poured into batteries of this type, which also speeds up the heating process. You can use a thermostat. A small volume of coolant is an important indicator for the efficiency of autonomous heating systems, since it is not necessary to heat and drive a large mass of water through the pipeline.

Interesting! After 4 days of continuous operation, an oxide layer appears on the inner surface of the radiator, protecting copper from the mechanical and chemical effects of low-quality water.

The copper battery is resistant to corrosion, therefore it has a huge operational resource - ten times higher than radiators made of other metals. In the absence of external influences, copper will last up to 100 years. Other product benefits:

Due to the plasticity of the metal, the pipe is not afraid of freezing the system. The ice will not be able to break the copper pipeline.
If a water hammer or pressure drop occurs in a district heating system, threaded joints and welds usually become a weak point. The copper pipeline is connected by soldering, which withstands the critical pressure of water and steam.
The inner surface of the radiator is not overgrown with deposits, because. copper prevents the reproduction of organic matter.
The main disadvantage of copper batteries is their high cost.

Conclusion

When choosing heating appliances for a private house, first of all, they take into account the type of existing heating system. For centralized, cast-iron, bimetallic or copper radiators are usually chosen. They successfully withstand the high pressure of the coolant, including pressure testing, are inert to chemically active substances, and have a significant service life.

Aluminum and steel batteries are suitable for an individual heating system. Prepared water is used in an autonomous pipeline, there is no overpressure and critical temperatures. Important factors are low weight, attractive design and reasonable price of devices.

I am often asked the question: which heating radiator is better for a private house? And for an apartment? And why? I decided to give answers in the form of an article, for sure someone is now looking for answers to these questions.

By design, radiators are divided into:

sectional and block made of cast iron, aluminum, steel, bimetallic;
columnar steel, aluminum or other non-ferrous metals;
steel panel.

Design water heating radiators

Now design radiators are popular, I have seen really beautiful radiators. A good collection of radiators from the Russian manufacturer Varmann.

Abstract Radiator Design

Another beautiful radiator from Varmann.

Within the framework of this article, I will not consider in detail the design of radiators. Just know that such radiators not only exist, but are also gaining popularity. At least, I meet such radiators more and more often.

Types of sectional radiators

Sectional radiators are aluminum, cast iron, bimetallic and steel.

Aluminum sectional radiators consist of sections made entirely of aluminium. The main advantage is not high cost.

Cast-iron radiators are not only Soviet ones, and everyone is familiar with the MS-140, but they are also quite nice. KONNER cast iron radiators look good, we installed these radiators several times with.

Cast iron radiators work well in gravity (gravitational) heating systems, if the heat source is a solid fuel boiler, then such radiators protect the boiler from boiling.

Bimetal radiators are made of aluminum, but the inner tube part is made of stainless steel. The main advantage is high resistance to pressure.

Steel tubular radiators are not common to me. I would classify them as design radiators, not every customer agrees to install them.

Types of steel panel radiators

Each steel panel radiator has a type designation, for example: 22 500*1000. The last digits 500 and 1000 mean height and width radiator in millimeters.

Type 22 is probably the most common type of radiator. There are several types of fins:

10 Type - smooth panel

11 Type - panel with fins

20 Type - two smooth panels

21 Type - one smooth panel and one with fins

22 Type - two panels with fins

30 Type - three smooth panels

33 Type - three panels with fins

Different types of radiators are made in order to have different power with the same overall dimensions.

Panel radiators can be of different heights, the most common are 300 and 500 mm. The most common type is 22.

Is aluminum or bimetal radiator better?

The bimetal radiator is made of two metals: aluminum and stainless steel. Stainless steel core is harder and stronger than aluminum + no chemical reaction with other metals.

If you have aluminum radiators tied with copper pipes - expect trouble, the radiators will clog over time and stop heating. Even during a chemical reaction, hydrogen is released, it will not break the radiator, but the heat exchanger on the boiler is easy.

Attention!
Copper reacts with aluminum and zinc. In heating systems, it is better not to combine these metals.
If you want details with tedious formulas, read an article in the magazine S.O.K.

Cheap sectional radiators

I strongly advise against buying cheap sectional radiators, their service life is less than 10 years.

Do not forget that in steel panel radiators, as a rule, fasteners, Mayevsky taps, plugs, come with the radiator, and in sectional radiators, as a rule, all this needs to be bought separately.

Which heating radiators are best for a private house

For a private house, steel panel radiators are best suited. They have optimal price quality better heat dissipation than other radiators.

My top 5 steel panel radiators for a private house:

PURMO

KERMI

VOGEL & NOOT

BUDERUS

WIESSMANN

PRADO

LIDEA

CALOREE

I am from the Krasnodar Territory, so you may not have any brands of radiator manufacturers, and for sure there are other brands that are no less worthy. Of all the brands of radiators that I have worked with, these are the ones I like the most.

Which heating radiators are best for an apartment

For apartments, bimetallic radiators are best suited. But, if the operating parameters of the heating system are below 5 bar, the heating system is not connected directly to the heating networks, but through a heat exchanger, the developer and the management company did not indicate which radiators to install, then aluminum, steel or cast iron radiators can be installed.

A bunch of restrictions, the benefit is dubious, the risks of flooding the neighbors, so I think that it is best to install bimetallic radiators in apartments, which, in principle, are indicated by the developer in 99% of cases.

My top sectional radiators:

RIFAR

GLOBAL

MONLAN

I repeat, I am from the Krasnodar Territory, so you may not have any brands of radiator manufacturers, and for sure there are other brands that are no less worthy. Of all the brands of radiators that I have worked with, these are the ones I like the most.

Put reliable radiators in apartments, in case of leakage, there will be sad consequences. In a private house, during a heating leak, part of the laminate may swell, but in an apartment, when you flood your neighbors, you can shake it up for a large amount.

Don't save on radiators! And check what your builders put in your apartment. Are you sure you trust them? They will install cheap heating appliances, and if there is a leak, you will pay your neighbors.

False information written by radiator manufacturers

Many manufacturers overestimate the performance of their radiators. Basically it's heat dissipation. A striking example is the Lammin ECO AL500-80 radiator.

They claim that the heat output is 190 watts from each section, but in fact 128 watts. Almost half overestimated heat transfer.

We all know that heating is heat loss compensation. Relatively speaking, we have a room with an area of 20 m², in which we need to install a radiator of some capacity. Some of you, and perhaps your unfortunate heating installers, have heard that 1 radiator section should be installed per 2 m². Someone has heard the figure of 100 W per 1 m², so they are guided by it.

Let's imagine two scenarios for the development of events, one with unfortunate installers, the second with normal installers, like us.

Unfortunate heating installer

Option 1. A room of 20 m², so you need 20/2=10. I'll install 10 sections, everything will be fine, this eccentric thought.

Option 2. A room with an area of 20 m², heat loss of 100 W per 1 m², which means 20 * 1000 = 2000 W. The power of one section of the Lammin ECO radiator is 190 W. To find out the number of sections, you need to divide the number of heat losses by the section power, 2000/190 \u003d 10.5. If rounded up, then you need to install 11 sections.

Normal heating installers

We consider heat losses in the program. It turns out that the heat loss of the room is 2700 watts. We select a radiator based on many parameters, such as: appearance, dimensions of the room, and of course we are guided by the results of testing radiators.

Conclusion

The unfortunate installer installed a radiator for 10 or 11 sections, let it be the maximum: 11 sections. We consider: 11 sections * 128 W (actual heat dissipation) = 1,408 W. But in reality, you need to compensate for 2,700 watts. Of course, when it gets cold outside, it will be cold in this room. In fact, you need to add 10 more sections.

So it turns out that here the installer did not count, here the manufacturer deceived, and you, my dear Customer, will freeze.

The autonomous heating system of a private house allows you to choose any heat radiators.

However, it is important to consider them characteristics and features of the location of the interior to organize the heating of the house most economically and efficiently.

What to consider when buying, and what devices are best used for autonomous heating?

Selection of the best radiators for a private and country house

Private sector heating differs from centralized by the absence of water hammer and stable low pressure.

It also differs in closeness and lack of gas saturation. Therefore, the choice of radiators for your own housing is not limited to the conditions of the general system, but depends on the preferences of the owners of the premises.

However, there technical features, which must be taken into account when installing certain types of heating batteries. Namely:

Durability and price of the heating device.
The external shape, the presence of protruding edges and corners, safety and the possibility of injury.
The dimensions of the room and the characteristics of the heat transfer of the heating device.
Calculations of the required amount of heat and the number of sections, the area of \u200b\u200bthe heating radiator.

Also, when choosing batteries, consider their appearance and the possibility of installation in the system.

Types of heating radiators

There are several types of heating radiators: cast iron, aluminum, bimetallic and vacuum.

Cast iron for brick, stone, wooden buildings

Cast iron batteries - universal radiators for heating brick, stone, adobe and wooden houses. They are almost always installed in high-rise buildings and are often used in the private sector due to their low price and the most impressive durability - 50-100 years old. High resource is achieved due to delayed corrosion and thick walls.

Photo 1. Cast iron heating radiator with decorative forging. It not only heats the house, but also decorates it.

Batteries made of cast iron have large internal sections. Therefore, the flow of water in them is not complicated by mechanical impurities, rust, and precipitation. coolant does not require filtration and frequent air bleeding.

With regard to the private sector and modern heating trends, cast iron radiators have one drawback. They have high thermal inertia, warm up for a long time, so they are difficult to use in thermal control systems.

What else to consider:

corrugated shape with stiffening ribs, which can cause children's injuries. You can warn them by installing a protective grid, screen.
Significant weight and the load on the foundation, difficulties with transportation and exactingness in the quality of installation.

conclusions: cast iron batteries are the traditional choice for hot water heating systems. They durable, reliable and inert. Perfect for traditional brick houses, the heating of which works in standard mode. They can be installed in systems from which the liquid is periodically drained, or in which there is an open expansion tank. When adjusting the temperature, it must be taken into account that the heating system with cast-iron radiators must be “screwed on” or power must be added in advance.

Aluminum

Modern batteries that differ from cast iron predecessors weight and low thermal inertia.

They have an attractive appearance, a simple flat shape, due to which they rarely cause injuries.

But the main advantage - aluminum batteries have high heat transfer coefficient, which allows their surface to quickly heat the air.

Aluminum radiators are economical in every respect. Their less weight cast iron batteries 4 times(1-1.6 kg in one section aluminum vs. 5-7 kg in one section of cast iron). The inner cavity contains 2.5 l coolant (for comparison - in cast-iron batteries, one section is placed up to 10 l). Warm-up time - 6 times faster than cast iron structures. The only lack of savings is in the price of aluminum. They stand in 2-3 times more expensive.

Disadvantages of aluminum heaters:

Life time- less than that of cast iron and is 15-20 years. Shortened service life is due to aluminum corrosion and thin battery walls. You can deal with the disadvantage by controlling the quality of the coolant, which is quite possible in autonomous heating systems of a private house. The heating system must be completely closed, distilled liquid is poured inside.
During corrosion, hydrogen is formed inside aluminum batteries. This causes air bubbles to form. Which in turn initiates the appearance of cracks and leaks. This disadvantage is overcome by installing bleed valves. They should work automatically.

conclusions: aluminum batteries can be installed in the heating system of a private residential building with a closed expansion tank, subject to control of the composition and quality of the coolant. The heating system needs fill in a special fluid, install automatic bleed devices. These batteries are ideal for thermal management.

Bimetallic

Bimetallic batteries are one of the latest expensive developments that have emerged as an alternative to rapidly corroding aluminum batteries. Bimetallic structures soldered from two metals- steel core and aluminum case. This combination improves corrosion resistance(steel corrodes less than aluminum) and maintain high heat dissipation thanks to the aluminum surface.

Photo 2. Bimetallic heating radiator mounted on the wall. The device consists of several sections.

Bimetallic heaters - ideal for private houses with any walls. Due to their low weight, they are installed inside heavy brick buildings and hung on the walls of light frame houses. the only disadvantage bimetallic batteries is their high price.

vacuum

The last advertised model of heating batteries with reduced fluid pressure inside. Positioned as a high performance design that quickly gives off heat and heats the space efficiently. However, vacuum batteries are heating devices. with unproven efficacy. They have a lot of negative reviews and a high selling price.

The device of a vacuum battery differs from cast iron and aluminum batteries the presence of a sealed internal cavity, inside which ethanol (alcohol) vapors or lithium bromide saline vapors circulate. These substances are coolants, their circulation is limited by the radiator cavity, inside which the pressure is greatly reduced (pumped out to a vacuum level). Reducing the pressure ensures the conversion of alcohol and lithium bromide into steam.

Through the inner cavity of the vacuum radiator a pipe passes through which a conventional coolant moves- water.

From hot water, the pipe inside the radiator heats up and transfers heat to the vaporous coolant. Steam settles on the cold surface of the outer walls of the radiator and gives them heat.

So the fluid circulation occurs with its constant evaporation and condensation. These processes provide heat transfer.

Such complex explanations of the operation of a vacuum radiator do not always make it possible to understand how the efficiency of its operation has been increased. In fact, many customer reviews say that vacuum batteries consume less energy, and at the same time also warm up the room worse. To achieve the same effect, two vacuum heating radiators have to be installed instead of one aluminum section.

Types of steel batteries

There are two types of steel radiators: tubular (sectional) and panel. They differ in design and price. There are also convector models with a built-in blower. What to choose for heating your home?

Panel

Panel radiators represent the cheapest heating battery designs.

They are enough effective, practical and safe, since all the tubes and protruding ribs in them are covered with a flat steel casing.

Their appearance resembles a flat box, suspended from the wall under the windowsill and radiating heat.

Another advantage of steel radiators - their price. In combination with low weight, ease of installation, aesthetic design, the price makes panel structures popular among buyers and developers.

Attention! When choosing a steel panel radiator, it is important to remember its service life - 20-25 years old.

Tubular

Tubular structures differ from panel ones in price - they are more expensive. Technical characteristics of the two designs are comparable. There is a slight difference in operating pressure inside the batteries. Tubular radiators can withstand more pressure than panel radiators. But for the private sector with an individual heating circuit, this factor is not important.

Tubular radiators also called sectional since each pair of pipes are combined into one section.

The heating battery consists of several sections, the number of which determines the amount of heat that the radiator radiates over a period of time.

Important for the private sector: if in multi-storey buildings an increase in the number of sections leads to better heating of the room, then in the private sector the situation is different. The heat radiated into the room depends little on the area of the radiator. It determined by the heat coming from the heating furnace. With an increase in sections in a room of a private house, the amount of heat in the system remains the same. Therefore, it is possible to significantly improve the efficiency of heating only by upgrading the heating furnace.

Convector

Convector radiators have built-in fan, which the provides movement of heated air. The name "convector" is associated with the physical term "convection", which means the mixing of air flows. In heating a private house, convector models are often used as portable batteries of the simplest connection.

For their work, it is enough to conduct electricity to the house and equip wiring, sockets suitable for power. Electric convector installed in the room, ensures fast heating.

Photo 3. Floor convector heating radiator. At the top of the device there are holes through which warm air passes.

Convector radiators affordable and less affordable in paying for their work. For electric heating of the house, it is necessary to insulate its walls, ceiling and foundation with high quality. Then heating with heat convectors will be efficient and affordable. - an alternative to cast iron batteries for energy-saving and frame buildings.Odnoklassniki

Which heating radiators are better to choose for the house

Living outside the city has many advantages, but to provide comfortable living conditions, you need to make a lot of effort. One of the most important points is the selection and installation of the heating system. It should not only work efficiently, but also save the family budget. And for this, you should purchase the best option for a heating battery.

What factors should be considered when choosing a radiator

In any hardware store there is a huge assortment of heating equipment. For this reason, before going to the building supermarket, determine the following parameters, on which the amount of heat required for the room will depend:

Thermal losses of the building (taking into account: decomposition of the building material (refers to wood), ceiling height, number of windows and doors, glass thickness, etc.).
Required temperature.
The thermal power of the device is determined by the following formula: S * h*41:42, where S is the area of the room; h is the height of the room; 41 - minimum power per 1 cubic meter S; 42 - nominal thermal conductivity of one section according to the passport.
The heating radiator, as a rule, is located under the window, therefore its maximum size is determined by the following measurements (in cm): from the floor 7-12, from the walls - 3-5, to the windowsill - 10-15.

It is also important to note for yourself:

weight (the complexity of installation depends on it);
appearance (affects the aesthetics of the interior);
value for money (is the determining factor).

Which heating batteries are better: types and characteristics

All heating radiators differ in design and class of material used.

According to the shape and texture, there are many options, it all depends on your taste preferences. Whether they are wide or narrow, plain or colored, backlit or with designer painting - it's up to you. The main thing is that they function according to the declared characteristics.

Regarding the method of operation and the type of material used, batteries are divided into 4 classes:

cast iron;
aluminum;
steel;
bimetallic.

To understand which heating radiators to choose for a private house, you need to consider their options in more detail.

Cast iron

For more than 100 years, cast iron heating technology has been very popular. This is justified by the number of positive qualities of cast iron batteries:

Significant heat dissipation (they heat up to 130 degrees and remain hot for 5-6 hours).
Durability (service life can be 50 years or more).
High level of strength (external mechanical damage, as well as high pressure inside the system will not damage the structure).
Corrosion resistance under sudden temperature changes and constant influence of condensate.
Unpretentiousness to the quality of the coolant (filters at the inlet to the heating system are not required).
Availability (low cost).

However, such systems, due to their shortcomings, are gradually being replaced by other, more advanced ones.

Cast iron heating radiators are larger than other models, which makes them difficult to transport, install and maintain. They also have other disadvantages in operation:

Low thermal conductivity. For good heat transfer, it is necessary that the temperature of the coolant be 70-80 degrees. (Justified by the massiveness and porous surface of the metal).
They require systematic care (periodic painting and cleaning).
Bulky (take up a lot of space). They do not fit into the interior of the housing, although original fences or partitions can be used to improve their appearance. There are also special design solutions from French and German manufacturers that will look good with a certain style of interior. These batteries look very nice, but their cost is high.
Require good fastening to the wall due to the large weight.

Cast iron batteries are produced in China (KONNER and Tokio) and Russia (MS-140).

Aluminum

Aluminum is distinguished by significant thermal conductivity, therefore, products made from it are very productive.

Advantages:

Ease.
Compactness.
Powerful working pressure (12-18 atmospheres).
Ease of operation (sections are easy to remove / install).
Significant heat transfer due to the shape of the sections.
Increased heat transfer. Due to the volumetric cross-sectional area of the intercollector tubes, the heat agent circulates faster and gives off heat to the metal.
Variety of sizes.
Acceptable price.
Attractive appearance.

Along with the advantages of aluminum radiators, there are also disadvantages:

Increased susceptibility to pressure drop and composition of the heating agent (quality filtration and pressure gauges are required to control filling pressure).
Instability to chemical factors (corrosion), so pay attention to the presence of a protective polymer film (coating) on the surface of the product.
Rapid wear (10-15 years of operation).

According to the layout of the sections, there are three categories of aluminum radiators: solid, arranged sectional and combined. But which heating radiator is better:

One-piece is distinguished by strength and plasticity;
Arranged sectional panels (typesetting) make it possible to replace failed plates;
Combined - combines both functions, but also costs more. Similar systems are manufactured by companies: Condor, RIFAR, Global, Ferroli.

Steel

They are divided into three subgroups according to the structure of the internal system.

Panel

Rectangular radiators, consisting of two welded panels with grooves, recesses, dining channels, in which the carrier circulates. Such a heating battery is quite light and compact, allowing you to dial the required temperature in a short period of time. Another name is convectors, since heat is supplied by convection (75%).

Their disadvantages include:

low working pressure;
shock sensitivity;
susceptibility to corrosion.

Manufacturers produce radiators with top and bottom connections, which allows you to lay heating in the floor. Manufacturing companies: Buderus, Lideya, Corado.

Steel sectional

Similar to cast iron, but have significant positive differences.

Strength provided by welded joints.
Internal pressure of 16 atmospheres.
Durability (up to half a century).

Although they are not available to a wide range of consumers, due to their considerable cost.

Tubular

It is worth noting their high price right away, because they stand out for their perfect design and effective functionality. Tubular radiators make it possible to implement your own design ideas in a heated room. Produced by foreign companies: Delonghi, Zehnder, Arbonia.

Bimetallic

According to the external features, they do not differ from aluminum ones. Their internal part is made of stainless steel or copper. This greatly increases their safety, service life and reliability.

Despite their cost, they have long and confidently been leaders in the heat engineering market. Therefore, we can say with confidence: which bimetallic heating radiators will last better and longer in your cottage - compensate for the money costs with the quality of work.

Based on the above, it can be noted that both subspecies are suitable for use in private homes. Now we will conduct a comparative analysis of a number of features and find out which of them should still be preferred.

Heat volume

An aluminum heating radiator (its section) provides 200 watts of energy. One part is released in the form of radiation, and the second is converted. Within 10 minutes after switching on, the air in the room begins to warm up, which makes it possible to save a lot.

Bimetallic heat transfer occurs differently: the steel core slightly slows down its spread. In principle, this indicator may differ depending on the model. Otherwise, there are no significant differences.

Heat carrier temperature

Bimetal is able to maintain water temperatures up to 130 degrees, but aluminum is only up to 110.

Life time

Bimetallic radiators combine the properties of two metals, therefore, their service life is longer (15-20 years) compared to their competitors (about 10 years).

Installation

Both radiators are light in weight, the steel mount is mounted on screws and ordinary plastic dowels. With the help of a set of keys and shaped tools, the installation and replacement of components is carried out.

Aluminum or bimetallic batteries, which is better in terms of service life

In our country, the composition of water includes many chemical impurities, and since aluminum tends to react with various substances, this is highly undesirable for it, since rust will simply eat its walls. For normal operation, the pH should not exceed 8 units.

Bimetallic radiators are better protected by a special coating from the effects of a too active heat agent - they are not so susceptible to rust. However, there are cases when hydrogen enters the liquid, then the components begin to rot very rapidly.

Manufacturers are constantly improving their products. And answering the question which bimetallic radiators are better, it is necessary to highlight the brands Polywarm, Teplopribor, Royal Thermo Vittoria, Sira. One of the most famous manufacturers is Kermi, Germany.

Outcome

Warmth in the house creates a cozy atmosphere. To always feel comfortable in your home, you need to correctly calculate the number of radiators and choose them.

When buying heaters for a private house according to the recommendations of experts, you can easily choose exactly those heating batteries that are best suited for you and satisfy individual needs.
