Heating radiators - which are better for a private house. Heating radiators: choosing the right option for a private house, installation technology Heating radiators in a private house which is better

The most optimal (and often the only) solution for providing heat at home is the system autonomous heating, which does not depend on the central gas and water supply. Therefore, all work processes related to the design, installation and maintenance of heating units and assemblies must be carried out by yourself - and pipe pipes, and install a heating boiler, and install heating radiators, choosing the best of the existing ones.

Features of autonomous heating

Both the heat in the house and the financial costs of heating and maintaining heating, heating and related appliances depend on the effective and competent calculation, selection and installation of heating radiators. Therefore, the first thing to do is to choose the type of heating, which can be air or water.

Air heating at home is heating with heaters or infrared heaters, electric fireplaces or heat from a conventional stove. Stove heating is the cheapest and easiest to implement, but its shortcomings (slow heating of rooms, low efficiency, high heat losses, dirt in the house) do not allow it to be used effectively. Electric heating by any devices is more progressive, but it is an expensive way of heating a house. Therefore, the choice of water heating in a private house will be understandable.

The advantages of autonomous heating over centralized are as follows:

1. Low pressure in the pipes, which minimizes the possibility of accidents;
2. The impossibility of occurrence of hydraulic shocks;
3. The possibility of limiting and adjusting the temperature in the heating system;
4. The ability to control the acid-base balance of the coolant, clean it from impurities and change it to a new one;
5. Easy operation of the system high efficiency and economy.

Applicable to sources of heat distribution, autonomous heating is advantageous in that heating radiators from any materials can be connected to the heating network piping - from cast iron, steel, brass, copper, aluminum, as well as bimetallic heaters. Such a variety of devices becomes possible because bleach and other reagents are not used in the coolant of an autonomous system.

Structurally, batteries or radiators are divided into tubular, panel, sectional and convector-type devices. Their advantages and disadvantages are described below.

Cast iron heating appliances

Traditional and well-known radiators are made of cast iron. In spite of wide range of products from other, more modern materials, cast iron appliances are still in sufficient demand among consumers. The popularity of cast iron radiators is explained by their advantages, including:

1. The strength of cast iron, durability in operation - more than 20-30 years;
2. The number of sections in the radiator, and hence its heat transfer, can be changed at your discretion;
3. Good anti-corrosion and chemical resistance;
4. Large inertia - cast iron heats up for a long time, and cools down just as long. Therefore, in case of emergency shutdown of autonomous heating, such radiators are preferable;

The strength of cast iron radiators is their advantage and disadvantage, which is expressed in the large weight of the products. Another drawback is that it will not work to quickly change the temperature of the battery. outdated appearance, rough surface and the same design do not attract lovers of exclusivity and originality. But for them, the industry produces steel, aluminum and bimetallic devices that have a well-thought-out diverse design and high efficiency.

Steel batteries and radiators

Steel radiators are produced in tubular and panel type. The panel construction consists of two figured plates up to 2 mm thick, which are connected in one housing using spot welding. Having a low inertia, steel batteries are capable of intense heat radiation, and their modern design and original forms of execution do not increase the cost of devices. But there are also disadvantages: radiators quickly rust with poor-quality paintwork, the metal reacts with reagents added to the coolant, a fixed number of sections in one device.

Tubular type radiators are distinguished by the fact that they have an individual original design, you can also choose different shapes of appliances. Tubular products are produced in which steel is coated from the inside with special polymer-based compounds, which increases their anti-corrosion qualities.

Aluminum radiators - advantages and disadvantages

Autonomous heating in a country house is a design of pipes and radiators with water as a coolant, and such a system is called water heating. For a private house with such heating, the most preferred type of heating devices will be aluminum radiators with the following performance advantages:

1. The small mass of the product, which allows you to mount devices even on drywall;
2. Aesthetics and design versatility - an aluminum radiator will fit into any room design, from retro and classic to hi-tech or modern;
3. High efficiency and heat transfer;
4. Temperature control by means of special valves mounted on the radiator housings.

Disadvantages, the knowledge of which will help extend the life of the aluminum case:

1. Additives that destroy the body must not be added to the coolant operating in aluminum batteries. You should also filter water or other coolant from solid particles;
2. The threads on aluminum are quite fragile, so you should carefully assemble the sections and screw in the taps and fittings, as well as watch for possible leaks.

Characteristics of bimetallic radiators

These are batteries, the case of which is made of an alloy of iron and aluminum. Structurally, it looks like this: the body of the device is sheathed with aluminum, and the coolant, when passing between the steel elements, does not come into contact with aluminum. A bimetallic heating radiator can also work in an aggressive environment of a centralized heating system due to its main advantages:

1. They withstand pressure up to 35 atm;
2. Have less weight due to aluminum coating;
3. high efficiency and low inertia.

There is only one drawback - bimetal products are more expensive than others, not counting copper or brass radiators.

Choosing a radiator according to its power

In order not to make a mistake in choosing and choose the right home radiator for your home, you should not immediately focus on its design - this is not the main thing for heating a house. The main thing is its power, and this value is indicated in the product data sheet. Knowing the volume of the room to be heated, it is easy to calculate the required radiator power. For example, for full heating of 1 m 2 in a room with three-meter ceilings and one window, ≈ 100 W will be consumed. Therefore, it is necessary to multiply total area rooms at 100 watts. For more accurate calculations, take into account the following corrections:

1. If the room has one window and 2 outer walls, then the result must be increased by 20%;
2. If the room has 2 windows and 2 outer walls, then the result should be increased by 25-30%;
3. If the window in the room faces north, then the result should be increased by 10%.

After such calculations, you can more accurately select a radiator. And it doesn’t matter at all which radiators you decide to choose, which ones are better for a private house and more efficient if they are installed incorrectly. In the best case, improperly located and connected radiators will serve as an interior decoration, in the worst case, they will interfere and clutter up the premises, but not heat them.

Let's look at where to mount radiators - this information will definitely be useful to you when you create a heating scheme. So, batteries should be placed under light openings - windows. This place always has the most heat loss, even if you have modern double-glazed windows installed. A radiator placed under the window will warm the air around it. After that, the heated air rises and creates a curtain in front of the window, preventing the penetration of cold into the room.

When choosing which heating radiators are best purchased for a private house, do not forget about the importance of the length of the appliances - it must correspond to the width of the window opening. In extreme cases, the length should be at least 50% of the width of the window. In a corner room, it is worth placing 1-2 additional devices along the outer walls exposed to cold air. If you are going to install heating risers, mount them in the corners, which will ensure their heating and avoid the possibility of blackening of the walls and the appearance of mold in them.

And do not forget that access to the batteries must be open. Many owners of private houses cover heating radiators with drywall sheets, which is undesirable - this will complicate the process of cleaning and repairing appliances if necessary. In addition, the use of such a fence will lead to a revision of previously performed power calculations.

We told you how and which radiators are best to choose for installation in a private house. Now you know that when buying appliances, you need to consider the quality of the water in the pipes, the power of the devices, their appearance, and even the ability to install on fragile partitions, if necessary.

Creation of an autonomous heating system careful approach to the choice of equipment. And if everything is relatively simple with the choice of a heating boiler, then you will have to sweat with the purchase of radiators. What radiators to choose for heating a private house and what to look for when buying them? In order to answer this question, we will analyze the features of autonomous heating systems, talk about their characteristics, and only after that we will give advice on choosing.

Also in our review, we will consider the features of all radiators available on the market and talk about their use in heating systems private houses. We will cover the following types of radiators:

• cast iron;
• steel;
• tubular;
• aluminum;
• Bimetallic.

For each variety, we present the advantages and disadvantages.

Features of autonomous heating systems

The heating systems of private houses differ from centralized heating systems not so much design features how many performance characteristics. Heating high-rise buildings requires high pressure in the pipes so that the coolant can rise to the upper floors, pass through numerous radiators, passages, taps and bends, and then return back. The higher the house, the higher the pressure, and the more durable the radiators and connections must be.

Autonomous heating system used in private houses consists of: boiler, pipes, radiators, expansion tank and circulation pump(used in systems with forced circulation).

As for autonomous heating systems, they do not need a lot of pressure - the maximum figure here is only 2-3 atmospheres. Therefore, heating radiators for the home can be anything from cast iron to bimetallic. Some settle for the cheapest models, saving money in their wallet, while others give their preference to more reliable, modern and durable radiators. But our verdict is that any heating batteries are suitable for autonomous systems.

What is the difference between centralized heating systems? They are observed:

• Low quality of the coolant;
• Powerful water hammers.

Coolant in centralized systems really disgusting. It is full of reagents harmful to pipes and radiators, a lot of dissolved salts and a lot of small mechanical impurities. Under such influence, only the most tenacious batteries survive, for example, cast iron or bimetallic ones.

Autonomous systems are good because here pure water, poured from plumbing system. At any time, water can be replaced, this will make the coolant cleaner. Often, alternative coolants are used here that do not react with metals and do not even freeze in the cold. That is, in autonomous heating systems there is no aggressive environment that could destroy pipes and radiators in the shortest possible time. Therefore, almost any type of radiators is used here.

When using steel radiators, it is recommended to create closed heating systems, since oxygen often enters open systems, which, together with water, begins to destroy not only batteries, but also pipes (metal).

Water hammers in autonomous heating systems rarely occur, since they are small in size, a small amount coolant and minimum pressure. Therefore, you don’t have to worry about this factor - feel free to install any batteries, but do not forget that any battery has its drawbacks.

Calculation of heating radiators of a private house

Table of characteristics of 1 section of a heating radiator, depending on the material and size of the section.

The uniformity of heating and the efficiency of the entire heating system depend on how accurately and carefully the calculation of the number of heating radiators in a private house is performed. The average thermal power of heating is 100 W per 1 sq. m. area. That is, to heat a room with an area of ​​​​20 square meters. m. need a radiator with a capacity of 2000 watts. If we choose a bimetallic radiator for heating with a heat output of 200 W per section, then we need a 10-section heater (or two batteries of 5 sections each). Cast iron batteries are characterized by lower heat transfer, on average 120-140 watts per section, so there should be more sections here.

Also included in the calculation process:

• Amendments to the type of glazing;
• The presence of thermal insulation and wall thickness;
• Ceiling height (the standard formula takes into account ceiling heights from 2.5 to 3 meters);
• The presence of heated rooms above the current room;
• Number of exterior walls (corner rooms are colder);
• Number and area of ​​windows;
• Climatic features of the area.

The most accurate calculations include taking into account the wind rose and the location of the outer walls relative to the cardinal points.

Connection schemes: "Leningrad", lateral connection and diagonal.

How to connect heating radiators in a private house? If you plan to run a one-pipe system, we recommend the Leningradka scheme with a jumper (bypass) for each battery. If you plan to use a two-pipe system, then a diagonal or lateral connection is used here. Adjustment of heating radiators in a private house is carried out using taps that block the supply of coolant. If necessary, taps can be placed on each battery - this will help even out the temperature in the rooms.

Adjustment is also available in a single-pipe system, but for this it must be performed according to the Leningradka scheme, with a bypass / jumper and three taps for each battery.

The choice of heating radiators in a private house

We have already figured out the features of the characteristics of autonomous heating systems and briefly got acquainted with the principles of calculating batteries. Now it remains for us to figure out how to choose a heating radiator for a private house and what to give preference to. Let's start with the old, but well-proven cast-iron batteries.

Bulky, heavy, but very reliable - this is how we can characterize cast iron batteries. They have the least efficiency, but they can survive any trouble.. At good care they easily serve for 50-60 years, and it is not known how long they could have served if they had not been thrown away during the next repair. These batteries are good with high heat capacity - they can keep warm during short-term heating outages (for example, they turned off the gas). They are also able to withstand any load.

They also have disadvantages. For example, the same high heat capacity of cast iron causes a high inertia of the system - after heat is supplied, it will take a long time before the batteries begin to warm the rooms. The disadvantages include the large internal capacity of the heatsinks, the enormous weight and the need to use bulky metal pipes to supply heat transfer fluid. Also, we can attribute to the minuses a low heat transfer, which ranges from 120 to 140 W per section - this is one of the biggest minuses.

The verdict is this - if you want to save on heating, and you already have suitable radiators and pipes, feel free to mount the system based on these components. Cast iron batteries are suitable for both one-story and two-three-story private houses.

Lightweight and very efficient - this is how we can characterize steel radiators. They are made of relatively rust-resistant steel and are characterized by high heat dissipation, unattainable for other radiators. They are characterized by ease of installation, which is associated with their low weight. Most often they have a panel form. This is what makes them popular in low-rise construction. They are also distinguished by low cost and low inertia - after 15-20 minutes you will feel how warm and comfortable it becomes in your house.

Panel steel radiators must be constantly filled with water - this will prevent the development of rust. It is for this reason that they often fail in multi-storey buildings, since there are often problems with tightness. In autonomous heating systems, as a rule, there are no such problems - they are simpler in design, they have fewer individual elements and connections. Therefore, they will serve here longer. But you need to ensure that oxygen does not enter the coolant - this will serve as a reason for the rapid oxidation of radiators.

Steel radiators are one of the most worthy solutions for heating private houses. They have high heat dissipation and are characterized by affordable cost. Of all the minuses, not very much can be noted good design but they are very practical.

More impressive tubular radiators are made of the same dough as ordinary steel ones. But if ordinary panel models cannot boast of a good appearance, then in the case of tubular radiators, we can see quite interesting solutions, including color. Such batteries are highly efficient, so they can be safely recommended for heating private houses. As for the advantages and disadvantages, they are the same as those described above. steel models.

Tubular radiators are convenient in that it is convenient to dry small-sized laundry on them, for example, children's clothes. But they are rarely found on sale, despite the fact that some manufacturers offer really interesting models - their price bites.

Considering the types of heating radiators for a private house, one cannot pass by modern aluminum models. These are inexpensive, quite reliable and efficient devices, well suited for installation in low-rise buildings. They withstand pressure up to 15-20 atmospheres and resist small water hammer well. Their main advantage is a small price, which goes well with excellent appearance. As a result we get a heating battery balanced in all respects for a private house- Inexpensive, effective and beautiful.

As for the disadvantages aluminum radiators, then this is the lack of resistance to a coolant with a high level of acidity. For this reason, such batteries cannot be installed in high-rise buildings with centralized heating, where the quality of the coolant is extremely far from ideal. But if you pour well-purified water with a neutral acidity index (pH) into your home autonomous heating system, then the batteries will last a long time, featuring good efficiency and heat dissipation.

Also, the list of disadvantages includes too intense convection, which is why you have to carefully select these radiators for the area and volume of heated rooms. It is best to entrust this to heating specialists.

The characteristics of aluminum radiators are similar to those of steel models. But they confidently captured the low-rise construction market due to their lightness, reliability, lack of rust, high heat transfer and low cost - the last parameter is the most significant for the domestic consumer.

Bimetal radiators

This is the most enduring type of batteries for private and apartment buildings. They are resistant to poor quality coolant, high heat output (literally a few watts lower than that of aluminum models - this parameter can be neglected), pleasant appearance, and endurance. These radiators withstand high coolant pressure and are able to withstand water hammer up to 50 atm. Bimetallic radiators are good in all respects, but lose a lot in price- their cost is very high.

Generally bimetal radiators well suited for installation in private homes. But is it worth spending so much money if there is no high pressure here, and the coolant is of high quality? Therefore, we can only recommend them if you have extra money in your pockets.

The heating system is the most complex engineering project in the house. Types of heating are constantly being improved due to high energy prices. Any heating system will work effectively only in the case of a competent heat engineering calculation and correctly performed installation.

The radiator heating system continues to function reliably in this century, having undergone some modernization. The number of heating radiators for installation is determined by calculation, and not "look like a neighbor." Do not compare houses, your house is not like that anyway. Only the correct calculation and high-quality heating system can create a warm and cozy atmosphere in your abode.

Classes of heating radiators

The modern market of heating equipment offers a wide range of design solutions and manufacturers. With such an abundance, it is easy to make the wrong choice, which in the end will lead to big trouble. For example, radiators in a central heating system are subject to the most severe operating conditions:

• Large and changing pressure in the system;
• The destructive effect of water hammer on heating devices reduces their service life;
• Increased corrosion and abrasive wear by the influence of a coolant saturated with oxygen and fine solid particles;
• Outside the heating period central system is without water, which contributes to the destruction of pipelines and radiators;
• Not everyone will withstand after that the pressure testing of the system before the start of the heating season high pressure, exceeding the working one and a half times.

Much better conditions operation of radiators in autonomous heating systems of private households, but even here there are a lot of "pitfalls". Traditional materials for their manufacture are steel, cast iron and aluminum.

These materials have different characteristics heat transfer, react differently to the coolant of the heating system, the life of the radiators and their cost depend on this. For example, copper would be ideal, but their price and service life are incommensurable.

Cast iron sectional radiators

Now many, living in "Khrushchev" and "Stalinka" began to consider cast-iron radiators a relic of the past, primarily because large sizes, not fashion design for modern interior and several layers of paint on them. Yes, and having worked for half a century in the central heating system, the end sections have not warmed up for a long time.

This is an operational problem, but not a reason for abandoning them when working in urban networks. Modern artistic cast iron casting and bold design solutions have significantly changed the appearance of cast iron radiators, while maintaining their efficiency and durability.

Advantages of cast iron batteries:

• The longest service life, more than 50 years;
• Resistant to corrosion and aggressive coolants;
• Large inertia at the termination of the heating system, up to 2 hours;
• High working pressure;
• Insignificant hydraulic resistance, which implies their operation in systems with natural water circulation;
• Low cost with unlimited service life.

With so many advantages of cast iron batteries, there are significant disadvantages:

• Large dimensions and weight make installation difficult;
• Brittle cast iron does not withstand water hammer;
• On sale, radiators are primed, so they require painting after installation;
• Heating occurs by radiation with slight convection, which complicates the uniform heating of the room;
• Increased inertia complicates the work of weather-dependent automation;
• A large volume of liquid, which in an autonomous heating system leads to an increase in fuel consumption.

Cast Iron Batteries Ideal inexpensive option for the system central heating and their use in individual systems of houses and cottages is not recommended (although when operating a coal-fired cast-iron solid fuel boiler, cast-iron radiators have proven themselves well).

Bimetallic radiators

The high cost of bimetallic radiators is due to their special design: durable steel pipes of the inner layer ensure reliable operation, and the outer layer of aluminum accelerates heat transfer and gives them a modern look. Their sectional structure allows you to adjust the size of the set and its power.

Their merits include:

• Long service life, from 20 to 50 years;
• Do not be afraid of water hammer due to the strong steel core;
• Aluminum housing provides high heat dissipation;
• Less susceptible to corrosion, which is essential when they are used in the central heating system;
• A small amount of liquid guarantees a quick response to the operation of the thermostat, which contributes to efficient and comfortable heating of the home;
• They do not require painting, aluminum gives them a pleasant appearance.

The high quality of composite radiators implies one and their biggest drawback: high cost. They have a nice appearance, so when looking for a manufacturer, you should rely on the wall thickness steel structure, the quality of the aluminum coating, the absence of aluminum contact with the coolant, etc.

Aluminum radiators

Aluminum has a higher heat transfer than cast iron and steel, its ductility allows you to give different shapes to the sections of radiators. Sections are made by pressing aluminum with the addition of silicon. Between themselves, they are connected by thread, and I assume the upper and lower connection to the heating system.

Advantages of aluminum radiators:

• Low inertia ensures rapid heating of the room;
• Light weight allows installation on plasterboard structures;
• High external attractiveness at a reasonable price;
• In addition to radiant heat, elements for convection heating are provided in the design;
• Service life without the use of Teflon internal coating up to 20 years;
• Respond quickly to room thermostat commands.

But there is a problem with the joint operation of aluminum batteries, steel pipes and copper-containing boiler structures that increase corrosion inside the radiator sections. And the low operating pressure generally excludes their installation in central heating.

The scope of aluminum batteries is quite narrow: individual systems heating houses and cottages, excluding boiler equipment with copper heat exchanger.

Tubular radiators

In the last century, cast iron was the main structural material, now alternative steel tubular and panel radiators have become popular. Tubular radiators represent the design of bent tubes located vertically or horizontally without stiffeners. Therefore, its effectiveness depends on the length of the tubes, their number and the pitch between them. Such a system is non-separable, which eliminates leakage on threaded connections.

Advantages of tubular radiators:

• Good heat transfer, which directly depends on the diameter of the tubes;
• aesthetic appeal;
• Light weight;
• Internal polymeric material reliably protects against corrosion;
• High working pressure;
• The absence of sharp corners, smooth shapes suggest installation in children's rooms;
• Variety of colors and designs.

Despite the polymer coating, the presence of welds has limited their operation in multi-storey buildings with central heating. There is a low resistance to water hammer and the formation of deposits that increase the hydraulic resistance and reduce the flow.

Panel radiators

When heating residential buildings highest value has a financial question: how to heat and how much to pay for it? This problem has made panel radiators popular due to the combination of efficiency and low price.

Such a heater consists of two stamped steel sheets interconnected with channels for the circulation of the coolant. The power of a panel radiator depends on the size of the welded panel and their number, for example, 33 type of radiator involves a three-panel design.

Advantages:

• Maximum heat transfer coefficient;
• High heating rate due to convection effect;
• The smallest volume of water, which ensures rapid circulation of water and reduces the cost of heating it;
• Light weight facilitates installation;
• Responds well to thermostat commands;
• The panels are painted and equipped with decorative grilles;
• The delivery set includes fasteners, a mounting kit, a plug and a Mayevsky crane.

But the small internal volume of water means it cools quickly, and the narrow channels and the presence of free oxygen limit their use in systems with natural circulation and in the central heating system. The working pressure of such radiators directly depends on the thickness of the steel panels.

Convectors (plate batteries)

Structurally, they consist of a pipe with a coolant, on which a plurality of plates are mounted. Such radiators have sufficient reliability, high heat transfer. Unlike previous radiators, installation in the floor is possible here, which significantly saves space in the living room. But it does not provide uniform heating of the room and there is a problem with dust removal when installed in the floor.

Which heating radiators are best suited for a private house?

What the owners of their own houses are proud of is their own heating system. Such a system operates at low coolant pressure, the water in the system is clean, there are no water hammers, which involves the use of radiators of any type.

But each type of radiator requires the creation of operating conditions for it, taking into account the design of the heating system (forced or natural circulation), its operating conditions (coolant water or antifreeze), type of boiler equipment (solid fuel boiler, gas steel floor, gas hinged double-circuit or electric).

For a private house, you should pay attention to two options: these are aluminum and steel panel radiators.

What you need to rely on when choosing the type of radiator for a private house

Comparison of working pressure and applications of different radiators

The power of the radiator section and its parameters

• Domestic section of cast iron radiator MS-140 with a height of 588 mm has a weight of 8.2 kg, a volume of 1.45 liters and a heating surface area of ​​0.244 sq.m;
• Aluminum radiator section 580 mm high, 80 mm wide and 81 mm deep has a weight of 1.35 kg, a volume of about 0.4 liters and a heat dissipation of 152 W;
• Section of a bimetallic radiator 564 mm high, 80 mm wide and 80 mm deep has a weight of 1.75 kg, a volume of 0.2 liters and a heat dissipation of 168 W;
• Steel panel radiator 22 types 500mm long, 505 mm high, 102 mm deep has a weight of 18 kg and a power of 1078 W (for comparison, an aluminum radiator of 7 sections will have the same power).

There are average data to determine the power heater: 1 kW will provide heat to a room of 10 square meters. m with a ceiling height of 2.5 m.

Radiator dimensions

Simple installation of heating radiators is due to their universal dimensions, which are suitable for most rooms and their parameters meet operational requirements. But this choice is not always made for aesthetic reasons; heat transfer conditions are of primary importance.

The number of sections of radiators determines their heat transfer and the reality of the installation in a place determined by the project. When installing a radiator under a window, to ensure its efficient operation, the distance from the radiator to the window sill must be at least 100 mm, from the bottom edge to the floor at least 80 mm.

It is preferable that the length of the radiator correspond to the width of the window opening. Thus, following these rules, one can choose optimal size panel radiator or decide on a set of sections of a sectional battery.

Design

In addition to standard radiators, their new design solutions for a non-standard interior have now appeared. For example, cast-iron radiators with decorative ornaments (retro versions) and original appearance, created by artistic casting, will decorate Vacation home, fireplace room, restaurant.

Now the market offers a wide selection of designer stainless steel heating radiators with a unique design. Often, in addition to the function of heating, they play the role of a heated towel rail or. The use of such radiators in the interior gives any room its own unique atmosphere of coziness and comfort.

Manufacturers

All countries whose geographic location suggests the presence of a heating season produce radiators. But the leading position is traditionally occupied by German companies with their guaranteed quality and durability (Kermi, Buderus, Oventrop). Finland (Purmo) and Italy (FondItal, Calidor, Radena) are not far behind them. Our customers are now most interested in cast-iron radiators Konner (China), well, we love cast-iron.

Price comparison table for different types of radiators

The above recommendations for choosing a radiator are not instructions for use, but are tips, since each type of radiator meets certain operating conditions, taking into account technical features of this heating system and the properties of the structures of the house or apartment as a whole. The size of the budget is also important, so it is advisable to find a "golden" mean between technical capabilities radiators and their price.

What radiators are better for a private house?

When, in the process of repairing or building new housing, it becomes necessary to install new radiators, the problem arises of their correct selection. Errors on this stage lead not only to unreasonable costs and significant heat losses, but also to breakthroughs, premature failure of devices. Do not forget that the operating conditions and parameters of open and autonomous systems differ markedly. Overview of heating batteries for houses and apartments, their comparative analysis and user reviews will help you choose the best set of equipment.

Varieties and description

Heating radiators (batteries) are varied in shape and size, but their main hallmark- the material from which they are made. This is what determines performance.

• Cast iron. They operate at temperatures up to +150 °C and pressures up to 15 atm. Thermal power sections - 80-160 watts. Battery life is up to 50 years. Pros: ease of installation, mechanical and chemical resistance of the material. Along with traditional products, more modern designs are produced.
• Aluminum - 10-15 atm, limit t \u003d 110 ° C. Power - 82-212 watts. Service life 10-15 years. Pros: fast heat dissipation, easy installation.
• Steel. Panel radiators are two sheets with water channels connected by welding. Operating pressure - 6-8.5 atm, t = 110-120 ° C, thermal capacity (depending on dimensions) 450 - 5,700 W. Pros: Efficient low temperatures, small thickness, reasonable price. Tubular devices operate at temperatures up to 120 ° C and 12 atm. Crimping pressure is 25 atm, so tubular radiators can withstand water hammer. The height of the products is 190-3000 mm, the depth is up to 230 mm, and the length is almost unlimited. Pros: high heat transfer rate and resistance to corrosion (if they are made of stainless steel).
• Bimetallic heating batteries. Their shell is made of aluminum, and the core is made of steel or copper. They work at 35 atm and t = 100 °C. Thermal capacity of the section at its very small sizes- 170-190 watts. Pros: chemical resistance, mechanical strength, low weight.
• Copper. Operating parameters: maximum t = 250 °C, pressure - 16 atm (crimping - up to 25). Radiators have absolute chemical resistance, increased heat transfer (2 times higher than that of aluminum). Service life - up to 50 years.

Requirements for batteries for home and apartment

An autonomous system is an undoubted advantage of a private house, since its parameters do not go beyond the calculated data. Centralized heating due to the instability of indicators requires compliance with a number of additional conditions.

1. Batteries for the home.

It is easier to choose a heating radiator for a private house, since a closed circuit has the following advantages:

• work at reduced pressure;
• lack of hydraulic shocks;
• limited coolant temperature;
• ability to control acid-base balance.

Taking into account the above positive aspects, any batteries can be connected to home heating, giving preference to products with the highest heat transfer and an optimal ratio of quality and price.

The best battery option for the home will help determine a short comparative analysis of their performance in local systems.

• Steel. Panel products - the most a budget option. Their heat dissipation is quite high, the thickness is small, they fit well into the interior. If in the house big windows, panel radiators create a thermal curtain, blocking the way for cold air. Tubular ones almost do not differ from panel ones in terms of technical parameters, but they have a more elegant look and therefore are more expensive.
• Oxidation due to poor-quality water is a significant disadvantage of steel batteries. They are recommended to be washed every three years so as not to slagging the entire heating structure.
• Aluminum. They are widely used in private homes due to modern design and high heat transfer. When installing aluminum radiators, their thermal conductivity is taken into account. If you put too many sections, the heated air rises very quickly, and the floor remains cold. During operation, the acid-base balance should be controlled, otherwise aluminum quickly corrodes without air access.
• Bimetallic. It is not economically feasible to install them in a private house, since increased strength is not in demand in an autonomous network with a pressure of 2-3 atm.
• Cast iron. Corrosion resistance, stable operation of radiators in old houses confirms their reliable reputation. They are more expensive than their counterparts made of aluminum and steel, but they accumulate heat better and keep it longer. As a result, gas costs are reduced.

2. Radiators for the apartment.

Good central heating batteries must withstand the negatives of open design:

• the presence of aggressive substances in the water chemical impurities and mechanical particles;
• temperature fluctuations;
• pressure surges - they occur during adjustments to pumping station or if air gets in after repair work.

The quality of the coolant is a barrier that does not allow you to choose some types of heating batteries for an apartment. Excessive acid content leads to failure of aluminum radiators. Air bubbles characteristic of open systems corrode the surface of steel products. The least sensitive to the composition of copper: on their inner walls a protective layer of copper oxide is formed. But this type is too expensive.

Comparison of cast iron and bimetallic radiators:

• Bimetallic. They withstand temperature fluctuations up to +130 ° C, pressure - up to 30-50 atmospheres. Corrosion resistance is ensured by a copper core, and a high thermal output is provided by a figured aluminum case. Durability is enhanced by the anti-corrosion primer. The appearance of neat compact products is also attractive, the only negative is the price.
• Cast iron. Radiators can last up to 50 years, regardless of the state of the coolant, they do not rust if the water is systematically drained. Iron-carbon alloy is chemically passive, and thick walls are not afraid of abrasive particles. Cast iron withstands fluctuations within 9-12 atmospheres, but powerful water hammers can destroy it. The disadvantage of batteries is a lot of weight, and at a cost they are more affordable than bimetallic ones.

User opinions

“A year ago, we replaced heating radiators in our 2-room Khrushchev with bimetallic ones - the Global Style 500 model. Although cast-iron batteries give off heat better, Global is much more efficient due to the shape of the sections. They are bent like petals and direct heated air into the room. We even have to reduce the heat supply - it’s good that there is a thermostat.”

Victoria, St. Petersburg.

“Last year we were persuaded to replace the old registers with aluminum Halsen. They look good, are expensive, and we did not feel the effect of the replacement. In the event of a power outage, the safety shutdown of the boiler is triggered. At the same time, aluminum cools down quickly, so I had to install 8-section batteries not only under the windows, but also along the walls. Gas consumption remained high.”

Alexander Kirillov, Tyumen.

“Having studied the reviews about good radiators, I decided to install Kermi flat wall steel radiators in my house. They quickly heat rooms, are hung on the wall and are almost invisible, easy to maintain. The main condition is a clean liquid without air pockets. I installed an electromagnetic filter-softener, before the start of the heating season I bleed air through the Mayevsky faucet.

Igor Fursov, Taganrog.

“Because of hard water, I was afraid to install aluminum batteries in the house. A year ago, I came across neat cast-iron radiators from the Chinese company Konner with good heat dissipation (150 W). For an area of ​​115 m2, I had to buy 90 sections (with a margin). But, apparently, the manufacturer overestimated the parameters - it was cold in the house, despite the fact that the system worked at the limit.

Dmitry Kovalev, Novosibirsk.

“Modern bimetallic radiators are best suited for an apartment. I was convinced of this by installing Sira RS three years ago. They are designed specifically for Russia: the steel filling is resistant to low water quality, and the outer shell of aluminum gives off heat well. The design is attractive, there are no sharp edges - this is important, since we have a small child. The height of the model and the number of paired sections (from 4 to 10) are easily selected.

Leonid Kizilov, Moscow.

Selection by technical parameters

The main criterion when buying radiators is the correspondence of their characteristics to the parameters of the system.

• The maximum allowable pressure. Batteries for central heating of an apartment must withstand at least 25 atmospheres. Although the operating temperature in the house pipes of the heating network is 10 atm, it goes off scale at the time of launch after the summer season, leading to hydraulic shocks. The least resistant to drops are steel batteries.
• Maximum coolant temperature. In autonomous heating, it is set by the user (no more than 90 °) and is maintained at the same level using a thermostat. For high-rise buildings the calculated value of the water temperature is 105 ° C, but it is not the limit.
• Heat dissipation. This parameter depends on the material from which the battery is made - the best heat conductors are aluminum and copper. In the accompanying documents, the manufacturer indicates the heat transfer of one element: on this basis, the required number of sections is calculated.

Comparison of heating radiators is carried out comprehensively, taking into account passport data and specific working conditions, segment sizes.

If the choice of a suitable design is made, it remains to choose a worthy company. Popular brands of bimetallic batteries - Italian Global Style, Royal Thermo BiLiner, Sira, Russian Rifar. Quality steel products are produced by Kermi and Zehnder. One of the best manufacturers cast iron radiators is German company Guratec.

The choice of batteries for heating in own house- not at all the same as buying batteries for operation in an apartment where the central heating system always functions. Heating a private house involves organizing your own heating system, which, as a rule, is based on a gas boiler. This and other nuances impose certain requirements on radiators.

To help you navigate the issue, Santekhbomba has prepared an article with recommendations. After reading it, you will find out which heating batteries are best for a private house, what you should pay attention to when choosing them, and also get an idea of ​​​​the main characteristics of the most popular batteries at the moment, suitable for working in gas heating systems.

Features of the gas heating system

First of all, it is worth identifying several features inherent in gas heating systems.

• Low working pressure.
• Absence of pressure surges and hydraulic shocks due to the closed circuit.
• The ability to use a good quality coolant, change its type or properties.

Based on this, such common types of heating batteries as cast iron and bimetallic should immediately be “sweeped away” from the selection. Yes, they are wonderful in their own way, but there is no point in using them in a closed system. Bimetallic ones, for all their merits, cost a lot - they are more expensive than aluminum and often even cast-iron counterparts, which will make their purchase completely impractical. Cast iron is simply not suitable for autonomous heating on gas. It's all about their high thermal inertia - because of it, you can't quickly heat up the room, and the efficiency of cast iron is such that using it in your home will be too costly. It will also prevent the automatic temperature control system, if any, from working. At the same time, the main advantages of cast iron come to naught - there will be no water hammer in such a system, as already mentioned, but to ensure good quality coolant will not be difficult.

If you are looking for heating batteries, which are best for a private house, only aluminum batteries remain of the options. But they should also be chosen based on your needs. To do this, let's take a closer look at exactly how they interact with gas system heating, what are their main advantages, and what characteristics should you pay attention to before buying.
