The floor-standing boiler is designed to operate on natural or liquefied (retrofit) gas. High power allows you to heat not only residential premises, but also production areas up to 320 m2. To supply hot water, it is possible to connect a boiler.

A cast iron heat exchanger in 5 sections will ensure reliability and increase service life (due to the fact that cast iron is 2 times less susceptible to corrosion than steel). For stable operation from the network, the installation of a voltage stabilizer is required.

Since the Vaillant atmoVIT VK INT 324 1-5 boiler has an open combustion chamber, it requires the installation of a vertical chimney for the natural removal of combustion products. A control system with a display makes it easier to set up and control the operation of the boiler.

Pros:

• Possibility of connecting a boiler.
• Gas control system.
• Automatic diagnostics.
• Reliable operation.

Cons:

• The expansion tank is not included.
• Heavy weight (99.9 kg).

1 Viessmann Vitogas 100-F GS1D871

Wall-mounted boilers with two circuits operating on gas fuel make it possible to provide supply of hot water to radiators (one circuit) And taps (second circuit) Houses.

Gas boilers are most often used to heat private houses.

Features of wall-mounted gas boilers for heating a private house

The wall mounting method applies to devices special requirements:

• compact dimensions;
• light weight;
• simple controls;
• modern design.

Often boilers are mounted on the walls not in separate buildings, like floor-mounted ones, but directly in the utility rooms of houses - for example, in the kitchen.

This is why boilers are made relatively small in size with a control panel on the front part. The housing has rectangular shape, which makes it easier to fit the device into the interior of the room.

The meaning of the parameters, which options are reliable

Power- a key parameter that allows the boiler to produce required quantity heat for heating and hot water supply (DHW).

It is of great importance when choosing suitable model and is calculated according to the principle 1 kW per 10 sq. m.

But no boiler should operate at maximum power, otherwise it will quickly fail. Therefore, when calculating the boiler power parameter, add 20% stock.

That is, for a house whose area is 100 sq. m., a boiler with a power of 12 kW.

Attention! If the boiler is required for year-round use, then you need to choose two-stage device or unit with adjustable power.

Camera type immediately affects a number of boiler operating characteristics. Combustion chamber closed type allows you to install the boiler in limited space. The main thing is that it is close external wall building through which is used with a closed chamber coaxial chimney.

For combustion chamber open type you will need to install a chimney and ensure air flow into the room. Thanks to closed system The closed type has higher productivity and savings than the open type. But a device with a closed chamber also costs more.

When choosing a fuel type It is important to note that modern boilers are designed to operate as on natural, and on liquefied gas. But it will be an advantage if there is a gas pipeline at the place where the boiler is installed, since it is cheaper, more convenient and safer. The characteristics of each device indicate what fuel consumption is when operating on natural and liquefied gas. By default, the gas boiler is configured to operate on natural gas, so when switching to a liquefied unit, you will have to reconfigure it.

Gas boiler efficiency — important parameter from the point of view of the ratio of the costs of operating the device and the results of its operation. The optimal efficiency range for wall-mounted boilers can be considered 90—95%. At low efficiency, more fuel is wasted, and at high efficiency, more expensive elements for the device are required - for example, copper heat exchangers.

Wall-mounted double-circuit boilers use heat exchangers made of copper and stainless steel. First transfer heat well second- more reliable in operation.

In the boiler they can stand as couples solid-steel, so steel-steel heat exchangers. One is responsible for the heating circuit, the other for the hot water supply.

There are also models of boilers with bithermal copper heat exchangers, the operation of which is organized according to the principle "pipe in pipe".

Hot water supply- an important function of a double-circuit boiler. Therefore, when purchasing it, it is worth studying in the data sheet such an option as DHW performance. Usually the parameters indicate at what temperature And how many liters the boiler can heat. For homes where hot water from taps is used quite often, this point plays an important role.

All these parameters must be taken into account in order to effectively use a gas boiler. At the same time, you should use its resource sparingly - for example, do not turn it on at maximum power for a long time. In case of regular care ( technical inspection once a year) and proper operation, the device can serve properly for quite a long time - on average up to 15 years. You can choose the appropriate option for a particular building by studying the rating of models. In it, the boilers are located as the coefficient of performance (efficiency) decreases.

Any dacha owner is faced with the question: how to improve the dacha heating complex. In any part of the Russian Federation it is necessary to winter period year to heat the home. It’s hard to imagine the life of a person living in the Russian Federation without a home heating system. Everyone knows that oil, coal, and gas are always becoming more expensive. There is a lot presented on the site heating systems dachas using absolutely different ways heat production. Any heating system can be used independently or hybridly.

Year after year, the popularity of double-circuit gas boilers is only increasing. Every season, heating equipment manufacturers offer new modifications of boilers with increased power, improved design and modern electronic equipment. Let's carry out brief overview gas double-circuit heating boilers, which are found on Russian markets.

Double-circuit gas boilers appear year after year in every season in new modifications, and at the same time their design and electronic filling are only improving.

The main function of a gas boiler is to heat the building, so the choice of the most suitable option must be made based on its main characteristics.

An important function of a heating boiler is to heat water for various needs. The need for warm water depends on the number of people who can use it at the same time, and for each family this need may differ significantly.

For heating domestic water, double-circuit gas boilers can be classified into three options:

• double-circuit gas boilers with flow-through DHW coolant;
• double-circuit gas boilers with a built-in boiler with a volume of 40 to 60 liters. This option is optimal for cottages and apartments with no more than 3 bathrooms (family up to 5 people);
• boilers with a boiler up to 500 l.

The choice of boiler type for heating systems is mainly influenced by the need for hot water, the cost of equipment and its installation. Let's give a brief overview of the different types of gas double-circuit boilers.

Review of double-circuit mounted boilers with a flow-through DHW heat exchanger

Dual-circuit mounted boilers with a flow-through DHW heat exchanger have high level reliability, allow their installation without extra costs, making them a good option for hot water supply and heating.

Dual-circuit mounted installations for heating - the most popular option for gas boilers, the main advantages of which are:

• performing two functions: providing warm water for various needs (no more than 2 water points) and heating of premises with an area of ​​no more than 300 sq.m;
• high level of reliability, which is achieved thanks to the presence of various safety functions and constant internal monitoring of the condition of the heating system;
• low costs taking into account component materials and installation work;
• modern design and compact dimensions allow them to be installed on any wall without disturbing the interior of the room, and mounted in kitchen furniture;
• equipped with all the necessary equipment for heating the building and heating water, which allows their installation without extra costs;
• have all the functions for water supply and heating, and are also easy to operate.

Double-circuit mounted boilers are mainly produced with a power from 24 to 32 kW and are divided into units according to cost:

• economy class, which are quite cheap and allow you to have hot water supply and heating at low cost;
• standard class, which are equipped with all the necessary functions for comfortable heating of the building and warm water supply;
• elite class - equipped with a fast hot water supply function and other useful functions with which you can achieve increased comfort;
• condensing type, which are characterized by durability, high reliability, silent operation and high efficiency, however, such units are quite expensive.

As the review showed, double-circuit mounted boilers are a good option for hot water supply and heating of a house, apartment or small cottage. It is worth noting that such units are capable of providing a maximum of 2 water intake points, because increasing them will lead to a decrease in water temperature. It is advisable that these points be located close to the boiler itself.

Review of double-circuit mounted boilers with a built-in boiler for 40-60 l

A double-circuit gas boiler with a boiler has antibacterial protection and will provide an unhindered supply of hot water to a family of 3-5 people.

This gas unit is the best option for a cottage and apartment and has a number of advantages over boilers with a flow-through heat exchanger. A built-in boiler of up to 60 liters makes it possible to spend about 400 liters of water at a temperature of up to 30°C in 30 minutes, and reheating the water is carried out in no more than 20 minutes. Such a boiler allows a family of 3-5 people to easily use hot water. One of the functions of such a boiler is antibacterial protection, in which the water in the boiler is periodically heated to 80°C.

The main advantages of these units are:

• high level of reliability thanks to a unique monitoring system and the presence of various security systems;
• equipped with all the necessary equipment in one housing, which makes them easy to install;
• simultaneously provide warm water to up to 4 water points, as well as heating rooms up to 350 sq.m.;
• easy to operate and maintain.

If we compare mounted boilers with a built-in boiler in cost and size with other types of heating systems, then they occupy an intermediate value between single-circuit units in combination with a boiler and double-circuit boilers with a heat exchanger.

Review of boilers with a boiler up to 300 l

Such units are divided into three groups:

1. Floor-standing boilers with a boiler up to 120 l.
2. “Combi” is a mounted single-circuit unit that is installed on a floor-standing boiler.
3. Single-circuit boiler and separate boiler up to 500 l.

The third option can provide warm water to a huge number of people, but when installing it you need to buy additional equipment. Such a unit takes up a lot of space and requires special skills when installing it.

Review of brands of double-circuit boilers

Let's look at the main brands that can be found on the Russian heating equipment market.

European manufacturers of dual-circuit units are represented on the market by the following brands:

• German: Wolf, Viessmann, Vaillant, Buderus, Bosch, AEG;

When the question arises about installing a heating system in your home, you will be faced with a huge range of boilers: from solid fuel, coal and wood fired, to gas and electric. But still, in our country, gas boilers are the most popular, since, on the one hand, the stability of electricity supply to the regions sometimes leaves much to be desired, and the cost of natural gas as a fuel compared to the cost of electricity is significantly less, respectively its use is much more economical. On the other hand, unlike solid fuel boilers, gas boilers do not require regular attention several times a day (to add firewood).

But even if you decide to heat the room natural gas, the problem of choice before you will not narrow significantly. Gas boilers are also available:

• wall or floor;
• single-circuit (for heating only) or double-circuit (heating and hot water heating), and double-circuit, in turn, come with a combined boiler or flow-through;
• steel or cast iron;
• volatile (dependent on electricity) or not;
• with multifunctional automatic or simple mechanical.

To determine the choice of boiler type, about them distinctive features you can read in the relevant articles on our website, and in this article we will review the most common brands of gas boilers from luxury to economy class.

Executive class gas boilers

This class of gas boilers is represented by the following most famous brands: Buderus, Vaillant, Viessmann (all from Germany), De Dietrich (France), etc.

First of all, all these brands are distinguished by the high quality of the equipment itself, high-quality service, provided, as a rule, by their own branded service centers, and of course, an appropriate price for the class, which can reach, for example, for a boiler for a small house of 100-150 sq.m. . depending on technical characteristics, $7,000 or more. The price is, perhaps, their only drawback.

Let's take a closer look at each brand.

Buderus

129-Buderus_Logano_G215

Buderus (Buderus)- one of the oldest (since 1731!) world leaders in the production of heating systems, currently part of the Bosch Thermotechnik GmbH corporation. It has the following types of gas boilers in its arsenal:

• wall-mounted gas condensing boilers (4.3 - 100 kW)
• wall-mounted gas heating boilers (7 - 28 kW)
• floor cast iron boilers, gas / diesel fuel (17 - 1200 kW)
• floor-standing steel boilers, gas / diesel fuel (71 - 19200 kW)
• floor-standing cast iron boilers, gas (9 - 750 kW)

More often in the countries of the former Soviet Union they are chosen in the latter configuration - a cast iron floor-standing boiler, but it is worth noting that such a choice, like the choice of any cast iron boiler, is justified only when you are equipping a house for permanent residence. If you put this boiler in your country house and turn it on for two days off, then at first you will wait a longer time compared to steel boilers until it warms up (first it warms itself up and then begins to warm up the coolant), and then, after you leave, the boiler will cool down for a long time, giving off heat to the street, which will lead to unreasonable overconsumption of energy carrier (gas).

The video provides an overview of the heating system based on the cast iron boiler Buderus Logano G234 WS

How to choose an electric heating boiler

If we talk with an open mind about electric heating boilers, then we should focus on Galant boilers, which are reliable and environmentally friendly. Without an open flame, electric boilers perfectly meet the requirements for safe operation. It is also possible to use electric heating boilers in apartment buildings, you don’t need a chimney to operate them. This is one of the significant advantages of electric boilers. However, when comparing electric and gas boilers, it is necessary to note the significant advantages of the latter, which are more economical in terms of energy costs. Therefore, the buyer's choice is more focused on

Many owners of private houses and industrial buildings are switching to independent heating using gas as an energy carrier: this is the cheapest and most profitable.
The market offers a huge variety of foreign-made boilers of different price ranges; there are also Russian gas heating boilers, the prices of which are more affordable. Let's take a closer look at them and try to understand the proposals of the domestic manufacturer.

A boiler is, first and foremost, a functional device, and it is not cheap to purchase. But the most important thing is that with the right choice, it is the boiler that can significantly reduce the costs of its owner, and the number of heating system repairs and the frequency of visits depends solely on the successful choice. service centers and the participation of house residents in the maintenance of heating equipment.

Will the boiler start at the beginning of the season, will it have to be lit manually and how often, will it provide the maximum possible savings on heating, will the boiler lead to air pollution and the room in which it is installed, will it lose appearance over time and how long it will last - all this depends on the right choice boiler suitable for a specific room. Moreover, you can avoid all of the above inconveniences without overpaying, but simply by competently choosing heating equipment.

When choosing a gas boiler, you usually pay attention to the following characteristics:

Boilers are classified according to installation method, functionality and method of exhaust gas removal. According to the method of installation, boilers are wall-mounted and floor-mounted, according to the type of functionality they are single- and double-circuit, and according to the method of gas removal - with a closed and open combustion chamber.

Floor-standing boilers are in greatest demand: they allow heating a large area, are reliable and have a wide power range - 11–68 kW.

Russian manufacturers have learned to produce floor-standing boilers adapted to our operating conditions and capable of competing with imported models, therefore, having purchased a floor-standing gas boiler Russian production, you can reduce start-up costs and get a completely reliable heating device that is in no way inferior to foreign ones.

The storage unit can hold up to two hundred liters of water. Thus, if you buy a double-circuit floor-standing gas boiler made in Russia, two problems are solved at once - heating and hot water supply. Sometimes it is advisable to purchase a boiler for a single-circuit boiler, then it will work on the double-circuit principle. However, double-circuit boilers much more compact, therefore better suited for rooms with limited area. But they have a requirement: the flow of incoming water must be under high pressure. In addition, they are not suitable in cases where the bathroom is located at a great distance from the boiler itself.

Closed and open combustion chamber

As for the type of combustion chamber, an open chamber uses room air and exhausts exhaust gas through a chimney; a closed chamber (turbo) contains fans that take air from the outside and send combustion products there. Boilers with open type combustion works on the principle gas burners, they heat up themselves, warm up the air around them (hence the lower efficiency), and require some distance from flammable objects. Turbo models are considered more economical and safe.

Among domestic models you can find all the listed types of floor-standing boilers, choosing according to the necessary parameters. Experts believe that modern Russian-made floor-standing gas boilers, even if they do not have highly competitive technical and operational characteristics, perform their main functions properly.

Popular Russian manufacturers of heating equipment

When choosing heating equipment at an affordable price, it is reasonable to proceed from considerations of individual needs, focusing not only on the brand. In general, reviews of floor heating are increasingly positive, perhaps this is due to a decrease in purchasing power, or maybe our compatriots began to trust local manufacturers more and gave themselves the opportunity to evaluate Russian equipment.

Domestic gas boilers have a number of advantages for Russian buyers:

• reasonable price;
• good service base;
• optimal efficiency.

Among the disadvantages of Russian boilers are:

1. large weight and dimensions;
2. inability to regulate temperatures;
3. often outdated design.

Zhukovsky Machine-Building Plant

The plant has been producing heating equipment for more than 40 years. The company presents boilers of three series (types) on the market: Economy, Universal and Comfort. Depending on the type, Zhukovsky gas boilers are equipped with imported automation or the development of our own engineers. The automation disconnects/connects the burner, monitoring the temperature in the heating system, monitors the readings of safety sensors and turns off the gas supply to the boiler if a potentially dangerous situation occurs. All ZhMZ models do not require connection to the electrical network. Among them there are both double-circuit (AKGV) and single-circuit models (AOGV).

Floor-standing gas boilers ZHMZ of the Economy series are equipped with an atmospheric burner, equipped with emergency draft sensors, are easy to set up, and have high efficiency. However, these models do not provide protection against overheating, which requires a more accurate calculation of power when purchasing a boiler, as well as periodic manual ignition of the igniter in cases where the protection is triggered. In addition, economy-type devices require a mandatory annual maintenance procedure before the start of the season.

But for Zhukovsky gas heating boilers floor price so attractive that these minor inconveniences can be ignored. In addition, the listed service features apply only to Economy series boilers. The automation of the Universal and Comfort models is more advanced (made in Italy and Germany, respectively). These models do not require maintenance, are reliable and unpretentious.

Price is one of the main advantages of Zhukovsky heating devices, but not the only one. In addition to their low cost, they have high efficiency (80 - 92%), a high degree of reliability and have a long service life. The standards of the plant, which, by the way, also produces special-purpose aviation equipment, lead to confidence in the durability and long service life of the heating equipment produced here. If you need a Russian-made floor-standing gas boiler whose price is minimal and whose operation is stable, perhaps you should take a closer look at Zhukov’s models.

Borinskoe

Like Zhukovsky, this plant has been producing heating equipment for quite a long time - more than 20 years. The company produces single-circuit and double-circuit boilers with the usual markings AOGV and AKGV, as well as boilers of its own design of the ISHMA series. All of them are equipped with imported automatic equipment, almost all models are energy independent, have a relatively modern design and low price.

The reviews for Borino gas boilers are quite good, they speak especially warmly about the ISHMA series models - they are additionally equipped with gas pressure sensors, providing the devices with an increased level of equipment automation and helping to reduce specific gas consumption by about 15-20%. An important advantage of Borin heating devices is the durability of the budget AOGV and AKGV series due to a reliable cast iron heat exchanger. True, this affects the cost.

For comparison, the heat exchangers of ZhMZ boilers are made of steel, so they are cheaper. Due to the cast iron elements, some models of Borino boilers are also heavy.

For those who are looking for floor-mounted Russian gas heating boilers that are particularly durable, it is worth considering models from Borinskoye OJSC.

In general, if you compare boilers by heat exchanger material, you should take into account some comparative characteristics cast iron and steel models.

Steel heat exchangers:

• cheaper than cast iron;
• easier to transport and install;
• They last a little less than cast iron.

Modern steel grades, when properly used, provide a service life of up to 30 years.

Cast iron heat exchangers:

It should be borne in mind that prices for floor-standing gas boilers made in Russia partly depend on the material of the heat exchanger.

If you need to buy a single-circuit floor-standing gas boiler that would look attractive, you should also consider Borinsky’s proposals. The boilers are coated with polymer enamel, which gives them an attractive appearance: they will fit well into modern interior and will look quite impressive. But there are also disadvantages: increased sensitivity to fuel quality and susceptibility to corrosion.

In general, Borinsky’s heating equipment is perhaps even the most reliable domestic gas floor heating boilers, the prices of which are significantly lower than similar offers foreign market. All models of Borinsky boilers are ideally suited for operation in Russia and are characterized by high efficiency, up to 90%.

"Signal"

The Engel heating equipment plant “Signal” has recently been gaining popularity. His gas boiler Signal KOV-10ST and other models are collecting good reviews, given the optimal price/quality ratio, however, installation of Signal boilers can be difficult due to divergent connector standards. Reviews for this Signal gas boiler are generally positive, as for other models of the manufacturer. They attract mainly due to their low price.

There are single- and double-circuit models on the market, the automation is imported, and they are moderately capricious in operation.

For many who decide to buy a floor-standing gas boiler, price often becomes the main selection criterion, but on the Russian market there is such a variety of heating equipment produced in Russia and the CIS at a relatively equal and affordable price that it is possible to choose a model in the same price range that matches requirements for all key parameters.

Many became interested in the small-sized and attractively designed Pechkin boilers (Taganrog), choosing as the main argument that, for example, the Pechkin KSG-10 gas boiler is small in size and equipped with an autonomous continuous water heating system. And someone chooses a Hephaestus floor-standing gas boiler, which has an original water-tube heat exchanger design based on the “Russian stove” principle, which ensures fast and efficient heating of the entire heating system.

You can buy a ThermoBar gas boiler (Ukraine) with a multi-section atmospheric burner, which ensures the purity of fuel combustion products, silent operation and avoids the accumulation of soot in the combustion chamber even at long-term operation device. You can read about other popular Ukrainian-made gas boilers. In addition to the manufacturers mentioned above, the Lemax and Rostovgazapparat enterprises have steadily occupied their niches.

Lemax

The offers of the Taganrog enterprise Lemax will be of interest to those who cannot decide on the type of boiler heating: Lemax offers solid fuel heating devices that can be easily converted to gas. The company offers gas boilers in three types, both single-circuit and double-circuit, the distinctive features of most of which are special coating steel heat exchanger, protecting the boiler from corrosion. There are models with cast iron heat exchangers. All boilers are equipped with imported components and have high efficiency, non-volatile.

Rostovgazapparat

Rostov equipment is valued for its design feature, which allows complete combustion of fuel. Heat exchangers at this enterprise are made of steel, cast iron and copper. The boilers are equipped with high-quality imported automation.

Quietness, environmental friendliness, design, dimensions - any of these parameters can become a decisive argument when choosing. The main thing is that domestic manufacturers have learned to create heating equipment that is affordable and capable of competing with the foreign market.
