Heating batteries for summer cottages. Electric heating in the country with radiators, convectors, fan heaters and infrared installations. Overview of solid fuel boilers

The choice of radiators for your own home is not an easy task, especially for a person who is not familiar with the heating equipment market. To greatly simplify this process, we will consider all types of batteries and determine which heating radiators are best suited for your home.

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 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.).
• Necessary temperature regime.
• Thermal power 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 positive qualities 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 heavy weight.

Cast iron batteries are produced in China (KONNER and Tokio) and Russia (MC-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).
• Not resistant 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:

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

Steel

Divided into three subgroups according to the structure 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 immediately noting their high price, because they stand out perfect design and efficient functionality. Tubular radiators make it possible to carry out 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 inner part 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 money spendings 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, then this is highly undesirable for him, since rust will simply eat his 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.

When construction works in the house are completed, the question arises of how to arrange the heating system so that the house is warm. The main unit of the heating system is, of course, heating radiators. Their choice must be approached with particular seriousness, because the strength, durability and reliability of your system depends on it.

The downside is the prohibitively high price, which is beyond the reach of the middle class. You can buy cheap models of bimetallic radiators, but only the name remains of the qualities.

It is not advisable to use bimetallic radiators for a private house due to the high cost. They have the greatest strength, but the local network of the heating system does not have high pressure, so the advantage of this radiator is useless in this case.

By structure, radiators are divided into tubular, sectional, convector and panel.

Steel radiators

All batteries have their drawbacks, which are functional in nature. The convector radiator is durable, economical, safe and quite beautiful. The only negative is the high price, because they are made from high-quality and expensive materials.

Correctly give preference to one or another type of radiators will help such a characteristic as power. It's easy to calculate: in a room with a ceiling height of 300 cm and one window, 100 watts will be needed to heat one square meter. When the room has two external walls, add another 20%. If there are two external walls and two windows, add 30%. When the window exits to the north side - 10% should be thrown. An important factor will be the installation of radiators, because no matter how good you buy batteries, if they are installed incorrectly, there is still zero sense from this. Heat loss

1. Batteries must be placed under the windows
2. their length must correspond to the length of the window, or at least half the length
3. V corner room you can install an additional pair of radiators along the outer wall
4. it is better to mount heating risers in the corners. This will ensure their heating and the ability to avoid blackening of the wall and the formation of mold.
5. they must always be available.

When choosing heating radiators, you should rely on specifications radiators and the heating system itself, as well as the budget. With proper study, you can always find a middle ground for yourself.

A dacha is your own house in nature, but, despite all the external and internal beauty, you need to take care of the warmth inside the house. The central element of the heating system is the radiator.

But if you have a Russian stove in your dacha, you should not disassemble it, following the advice from and tiling it, you can only enjoy its appearance, but also use it as an alternative heating option in case of possible accidents.

Choosing a radiator manufacturer for a summer residence

On the one hand, choosing a radiator is easy because heating radiators are divided into only 4 types:

• cast iron;
• steel;
• aluminum;
• bimetallic.

On the other hand, despite the 4 choices, you need to find out and compare the technical characteristics, positive and negative sides certain radiators, and choose the most suitable for your dacha.

Cast iron radiators

Cast iron batteries are perhaps the oldest type, but still continue to be popular with buyers. TO positive aspects These radiators should include:

• High thermal conductivity;
• High service life;
• Efficient work with coolants of different quality;
• Corrosion resistance;
• Installation in any heating systems;
• Relatively low cost.
  But besides the positives, there are also negatives:
• Great weight;
• Difficulty in installation due to the weight of the structure;
• Small selection of models.

  Manufacturers of cast iron batteries:

• KONNER;
• MS-140.

KONNER– Russian trademark, which has been skillfully using for 10 years modern technologies and lightweight design for making quality radiators at affordable prices.
The products of this company are represented by 3 main collections:

Specifications:

Steel radiators

Steel radiators, in turn, are divided into two subspecies:

With sections-panels;

with tube sections.

With section panels

Panels can be types 11, 22, 33 (this depends on the number of sheets). Sheets are fixed to each other by spot welding.

Such batteries are designed for private houses and cottages that have individual heating systems, in apartment buildings on the contrary, they may not be up to the task.

Unlike cast iron, steel ones have a larger assortment; you can choose a model with a side, bottom or universal connection. Batteries with a bottom connection are more attractive and therefore more expensive.

Batteries can be tall, narrow, wide, suitable for any layout. In addition, a thermal valve is inserted into almost every manufactured battery of this type, so that you yourself can insert a thermostat and set a comfortable temperature.

Manufacturers of panel radiators:

Korado Radik;

German firm Kermi is the main manufacturer of high quality, powerful and at the same time attractive steel panel batteries. This company is already widely known even among buyers in Russia and Ukraine.

Such radiators are popular because of their quality and thoughtful details, there are models with special rounded edges, for the safety of your children.

Technical specifications:

Aluminum radiators

Today, aluminum radiators are less popular than others, due to the many requirements for the coolant, they are not protected from the effects of oxidation, and they cannot withstand water hammer (in multi-storey buildings).

If you nevertheless decide to install this type of radiator in your country house, please note that the system must have low pressure and a low-alkaline solution as a coolant.

But if you are a fan of aluminum radiators, then some manufacturers coat the radiators inside with a special compound so that they can withstand high pressure and oxidation, but of course their price is much higher than conventional ones.

Advantages:

• High heat dissipation;
• Easy to install and carry;
• Rapid heating of the room;
• Modern versatile design.

Flaws:

• Requirement for the acidity of the coolant;
• Requirement for other parts of the heating system.

Video about choosing a heating radiator

well-maintained Vacation home is an opportunity to escape from the tiring and noisy stone-concrete jungle and give yourself a break. In order to have a holiday in the country at any time of the year, the house needs a modern heating system.

Key elements any rational, convenient and efficient heating system are radiators. For a dacha as for a private dwelling with individual heat supply, and at the same time visited from time to time, the choice of a heating boiler and batteries is based on a number of criteria, seeming to be a search for the best solution in terms of price, practicality and reliability.

Distinctive features of heating systems of private houses

A private house, which is also a summer house, if it has a heating system, then most often it is individual. Autonomous heat supply differs significantly from the centralized one, which is typical for urban areas with multi-storey buildings and buildings for various purposes.

In order to decide which batteries to choose, it is necessary to analyze all characteristics highlighting the pros and cons of individual heating.

Method of heating a country house

It is possible, in principle, to heat a country house with electric heaters - ceramic-metal panels, electric warm floors, oil convectors, infrared heaters etc. Old coal or wood stoves today they are not even taken into account as a relic, from which, on the contrary, they seek to get rid of.

However, in order to quickly heat a frozen house with electrical appliances, you will have to face the following difficulties:

• they will need a lot - for each room there is a heater, or even two, which is expensive;
• it will be extremely costly, especially if you need constant heating for several days;
• is fraught with network overload due to exceeding the permissible load in terms of total capacity - rural networks are not designed for this.

The best solution would be to install a heating system, the center of which is a heating boiler with circulation pump, pumping the coolant (antifreeze or purified water) through an extensive system of pipes and radiators, the task of which is to transfer heat from the heated coolant to the room air. Correctly selected, calculated and correctly mounted option will provide economy, thermal efficiency, convenience and safety as in the case of installation gas boiler, and in the case of an electric, solid fuel or combined boiler.

Features of an autonomous heating system of a private house

Autonomous heating in the country is:

• low, in comparison with centralized large-scale heat supply systems, the created working pressure, as a rule, does not exceed 10 atmospheres. This is due to the relatively small size country house, after all, even a two-three-story cottage with a dozen rooms is not a hundred-apartment high-rise building of 9 or more floors. Much less, gentle pressure is required to circulate water through a small system;
• no risk of water hammer, which eliminates the requirements for the strength of heating radiators;
• lower operating temperatures of the coolant, sparing temperature regime for the entire system;
• opportunity self-selection coolant by type, composition, reaction, etc., as well as control of its condition. In turn, this helps to prevent the risk of corrosion.

It follows from the above that heating batteries can be absolutely anything: in terms of heat engineering and basic operational characteristics, all options offered on the market today by domestic and foreign manufacturers are suitable. Autonomous system will not create difficult, critical conditions for any of the types and models of batteries.

At the same time, even neglecting the indicators of maximum pressure and temperature inside the system, in order to make a rational choice of radiators, it is necessary to correlate the following parameters:

• heat transfer;
• material features;
• corrosion resistance;
• construction and design features;
• price.

This is necessary in order to choose the best equipment option, which will be appropriate from a functional point of view, taking into account the specifics of the operation of the dacha during the cold season, the characteristics building materials, climate features in a particular area, and also eliminate the risk of unjustified overpayment and high time and effort costs.

Types of radiators according to the material of manufacture and rating according to the characteristics of thermal efficiency

So, the basis for choosing suitable batteries for private heating country house is the search for the optimal solution in terms of thermal conductivity and price-quality ratio.

The thermal conductivity of the radiator is determined physical property thermal conductivity of the material from which it is made. If you rank the types of radiators by increasing the value of thermal conductivity from the lowest to the highest, then it will look like this:

• cast iron radiators - with the lowest thermal conductivity, warm up for a long time and heat the room, but also cool down for a long time;
• steel radiators;
• aluminum radiators;
• bimetallic modern options(steel tanks inside, aluminum casing outside);
• copper - the most heat-conducting, heat up quickly, give off heat well and warm up the space.

On the other hand, the natural desire of the modern consumer is to ensure a sufficient level of efficiency or efficiency.

The efficiency is influenced by the design and the area of ​​the heat transfer surface. Modern radiator models embody solutions that reduce costs through the use of cheaper materials, ensure the compactness of the heater, the aesthetics of its appearance, while expanding the heat transfer area and creating conditions for the formation of effective directional warm flows, thereby improving convection. In this regard, even many modern aluminum options may be preferable in terms of thermal efficiency and cost than copper.

The actual heat transfer and efficiency of the heater is characterized by the ratio of the heat transfer of the metal and the volume of the internal space filled with the heated coolant. The less coolant is required to provide high level heat dissipation, the better.

Cast iron radiators

The cast-iron version of the radiators, despite its former glory and prevalence, is not the most successful.

The advantages include high strength and resistance to water hammer, they are inert to corrosion and undemanding to the quality of the coolant, retain heat well and create significant thermal power.

The main disadvantage is significant weight and bulkiness, which make it difficult to use cast iron batteries in country houses with thin, especially wooden or Scandinavian-built walls and ceilings. Warm up the frozen country house won't come out quickly either.

As a rule, cast-iron radiators do not have a presentable appearance, and for modern aesthetic models you will have to overpay a lot so that their cost will exceed the cost of steel and aluminum models.

Steel radiators

The use of steel radiators of the heating system for summer cottages is more preferable, especially panel options that are neutral in appearance, provide good heat dissipation, heat up quickly, are conveniently adjustable, have a light weight and are budget-priced.

However, steel is not resistant to water hammer, it is subject to corrosion, and therefore it is necessary to constantly monitor that air does not enter the system, for this reason it is also not recommended to drain water at all for the summer period. Otherwise, the service life may be reduced to several years.

Aluminum radiators

Due to the physical and chemical properties of this metal, as well as modern solutions in terms of design, aluminum radiators seem to be one of the best options heaters for suburban housing, because they:

• light and easy to install;
• withstand sufficiently high working pressure and temperature, and therefore in gentle conditions autonomous heating show high reliability;
• quite aesthetic;
• durable;
• characterized by high heating rate, thermal conductivity and heat dissipation.

For their value, they are a rational investment in providing coziness and comfort in the country. In particular, optimal solution according to the ratio of practicality, price and quality, you can choose among the range.

Bimetal radiators

To date, this is the most progressive solution, distinguished by aesthetics, efficiency, reliability and other valuable properties, which makes them the most expensive heating radiators. For a dacha designed for the periodic temporary stay of the owners, it is better to pay attention to more affordable options, and install bimetal in a private house for permanent residence or a city apartment with central heating.

Copper radiators

Excellent in terms of thermal and operational characteristics, copper heaters are plain in appearance and are too expensive, in addition, they do not tolerate proximity to aluminum - either all copper or brass elements are acceptable.

One of the main components of a home heating system is a radiator - a heating battery, as we used to call it. Consider radiators for heating - which ones are better for a private house, what are they made of?

Living in a private house has many advantages, along with this, a lot of worries and efforts fall on our shoulders, we strive to ensure that everything is equipped competently and of high quality. An autonomous heating system in a private house is one of the main aspects responsible for comfortable living. You will not be dependent on a centralized system, you will always be able to heat your home, regardless of the schedule for turning on the heating (as is the case in urban residential buildings). Your own heating system can be calculated and installed as you wish, and, of course, each of us strives to ensure that everything in this matter is done reliably, for many years to come.

The right choice of equipment is important both for the budget and for subsequent comfortable operation. Today, the construction market offers a wide range of modern heating equipment. When choosing radiators, you should consider options with a favorable price ratio and a limiting heat transfer rate. Judging objectively, any batteries can be suitable for a home heating system, but there are still certain nuances.

Heating radiators - which are better

What are modern batteries? If we consider the so-called steel options, then there are panel or tubular models. Despite the fact that they are considered the most budgetary, they are characterized by good heat dissipation, relative compactness. Panel models consist of two metal plates interconnected by welding. Due to their area, such radiators are able to give a lot of heat.

Panel option, photo:

Tubular options will come out to you a little more expensive than panel counterparts, they have a very concise appearance, somewhat reminiscent of old cast-iron batteries. They can have a variety of designs, shapes and sizes.

Tubular batteries, photo:

Some models of steel radiators have an internal polymer coating which prevents corrosion processes.

Advantages of steel structures:

• reasonable price along with high efficiency;
• do not oxidize from low-quality water;
• long operating life
• light weight
• convenient sizes.

The disadvantages include:

• rough appearance (panel version);
• require flushing every 3-4 years (to avoid slagging of the system);
• need constant filling with water (to avoid activation of corrosion processes).

Aluminum radiators

Due to their low weight, they can be mounted even on thin walls and partitions. They have an aesthetic modern design, have high heat dissipation. Cons - a short service life (15-17 years), susceptibility to corrosion, leaks can form at the joints of sections. According to the specifics of connecting sections, aluminum batteries are arranged, solid and combined. One-piece models are more reliable, they do not have connections through which water can seep over time. The assembled radiators allow you to replace the sections that have become unusable. Combined models have the qualities of the first two analogues.

Aluminum batteries, photo:

Bimetal heating radiators

They are considered the most "advanced" and improved. These batteries combine the qualities different types metal - aluminum heat dissipation, rust resistance (inside made of copper or steel High Quality). A bimetallic radiator has a layer of anti-corrosion coating both inside and outside (for more expensive models). The declared service life of such batteries is 40 years. They have a higher price compared to all other types of radiators, but the money costs are offset by quality and high performance.

Bimetallic version, photo:

Cast iron radiators

The most durable, reliable and time-tested. The first cast iron batteries appeared more than 100 years ago. Everyone knows their appearance, despite the fact that the life of this radiator is 50 years, they can still be found in many houses now. Such batteries cool down slowly, retain heat longer (compared to, for example, an aluminum counterpart) - this factor allows you to reduce gas costs.

Examples of modern cast iron batteries, photo:

Cast iron heating radiator is highly resistant to corrosion processes, has a large wall thickness. Despite the fact that the internal volume of the sections is quite large and requires a large amount of water to fill, this feature allows you to provide heat to a large area of ​​\u200b\u200bthe room. Such batteries are heavy and require appropriate powerful brackets for mounting. Over the years, their appearance has not changed much, but today on sale you can find ennobled versions of modern cast iron radiators. The outer surface of such structures has an improved design that is suitable for a certain style in the interior (classic, retro).

At a price, these radiators are more expensive than aluminum models, but cheaper than bimetallic ones.

Which radiators are good

After a small comparative analysis of the proposed models for a private house, we can draw the following conclusions:

• If you want a reliable economy option, then choose a high quality aluminum battery from a well-established manufacturer. They are aesthetic, have a low weight, and will work perfectly in a home autonomous heating system.
• If the issue of price does not bother you, then choose sectional bimetallic radiators - they are good in all aspects.
• Reliable, solid cast-iron options will keep heat in your house for a long time, and it is also very convenient to dry things on them in the cold season.

To the question - heating radiators, which are better for a private house, the answer will be this: in each individual case, you need to calculate your capabilities and take into account the requirements of your individual heating system. It is necessary not only to calculate the correct number of radiators, but also to produce high-quality thermal insulation of the whole house. If the dwelling is poorly insulated, not a single radiator will help in the fight against cold.
