Ten of the best wall-hung gas boilers. Which wall-mounted gas heating boilers are better - choice, price. By number of control modes

The classification of these units is quite complex. Taking into account the peculiarities of their installation and some restrictions associated with the specific heating of apartments in townhouses or small cottages, the most important parameters are the following.

1. Type of fuel

When choosing a model for an apartment or private house, you should focus only on gas boilers.

All others (solid, liquid or combined) are clearly not suitable for them. The reasoning is simple - any “fuel” (solar, pellets, etc.) must be stored somewhere. The option with an electrical device is also eliminated. In addition to installation difficulties (separate line, RCD, AV or differential automatic), there are two more problems.

• Grounding. How to connect the boiler to the corresponding bus? The services of a specialist will be required, and practical implementation (depending on the type of power supply) will be quite expensive.

• This heating method is not economically viable. Taking into account even the minimum power of the boiler installed in the apartment, the meter will add up a very tidy sum in a month.

2. Engineering solution

2.1. By installation method

There is no choice here - only a wall-mounted boiler. To install a floor-standing model, a separate room (furnace room) is required, as well as compliance with a number of requirements for the placement of gas equipment. For townhouses, small cottages, duplexes, low-rise apartment buildings - not an option.

2.2. By power

The most common advice that you can get from a store manager is to focus on the ratio of 1 to 10 (boiler power, in kW/apartment area, in m2). But is it really that simple?

• Not a single technical device can work for a long time at the limit of its capabilities - breakdowns are inevitable.
• No matter how well a home is insulated, it is impossible to reduce heat loss to zero.
• The intensity of heating is influenced by the material of the walls and the position of the apartment in the house (whether it is corner or not and a number of other factors).

Therefore, when choosing a gas boiler, the calculated power value (according to the given formula) should be increased by 30 - 35%.

2.3. By type of combustion chamber

It can be open or closed. Here you need to take into account the specifics of the structure.

• With open It is much easier to install a boiler in an apartment with a camera - you just need to connect its pipe to the general house smoke exhaust duct. Some disadvantage of this solution is that by taking air from the room, it “dries” it somewhat. But this is the best option for a gas boiler, and regular ventilation of the home eliminates this disadvantage.

• Closed the chamber involves the intake of air (to ensure the combustion process) from the outside. This means that you will have to hollow out the wall and install an air duct elbow (or a coaxial chimney). How rational this is and whether it is possible in principle depends on the type of building. Well, if a boiler is chosen to replace a boiler that has exhausted its service life, with an open chamber, it is definitely not suitable - the additional installation costs will be too significant.

2.4. By number of circuits

This is not difficult to decide. If your apartment or cottage has a instantaneous water heater (gas water heater), one is enough. But if it is necessary to provide both heating and hot water supply, then it is advisable to purchase a double-circuit boiler for a townhouse or private house, although it is more expensive.

Everything else is secondary and at the discretion of the buyer. For example, the type of control, the presence of a remote control, the number of options in the menu, shape, color scheme, and so on.

The best models of gas boilers for small areas

When purchasing a wall-mounted modification, preference should be given to imported units. They are fully equipped with everything necessary, and the only thing they require is a proper connection. It is undesirable to install domestic gas boilers in apartments and low-rise buildings - there are complaints about the functioning of the DHW circuit of the units, and some things will have to be purchased additionally. For example, an expansion tank.

Wall-mounted heating devices under the brands Bosch, Vaillant, Protherm, Lemax (entirely made from imported components), Baxi are in great demand.

Coziness and comfort depend on optimal temperature and humidity levels. The best gas boiler, which is of primary importance for heating a private home, will help create the necessary atmosphere. Today, there are several main classifications of devices of this kind, each of which is intended for specific conditions of use. But first of all, gas boilers must be reliable, safe and efficient; the rating of gas boilers from the editors of the Marka.guru portal will tell you how to figure this out and purchase the right one. It takes into account customer reviews of popular models, as well as the opinion of specialists in the installation and repair of heating systems. Now a little more about how to choose the best boiler and what criteria you should pay attention to.

There is always a risk of purchasing a model that is not quite suitable, but in order to minimize this possibility, you need to calculate the purchase criteria.

1. Power- the basis for purchasing a boiler; the efficiency of heating the room will depend on it. As a rule, 1 kW is enough to heat 10 square meters of area; if the ceilings in the house are higher than 3 meters, a small additional power reserve will be required. Double-circuit boilers will also require additional calculations, because constant heating of water will require additional energy consumption and increased productivity.
2. Layout- no less important for houses with limited space. A double-circuit boiler is designed for drainage and heating of several systems - heating and hot water supply. The single-circuit gas boilers used are installed together with a storage boiler, in which water for domestic needs will be heated. It will take up additional space, and this is not always possible.
3. Location. A modern wall-mounted gas boiler can have a compact size and a presentable appearance that will fit perfectly into the interior, for example, of a kitchen. As a rule, these are low-power models that are suitable for heating a house of 150 square meters. meters or less.
4. Safety and reliability. The best gas boilers today boast automatic operation and self-diagnosis. Computerized systems are able to select the ideal programs to heat the room at the required temperature. If there is a fuel leak, the boiler will turn off and signal a problem to the owner. And this is far from the limit of possibilities.

Conclusion

A reliable heating system is one of the most important components of a residential building, not counting the roof and walls. And if we choose a worthy device, it must certainly be safe, easy to operate and, if possible, economical.

The rating from the Marka.guru portal will help you find the ideal boiler for a private home; we hope it will orient buyers in the huge range of boilers on the market.

A gas boiler is a heating device that uses natural main gas to generate heat. This type of fuel is cheaper than electricity, which is why gas-powered devices are so popular. “Plumber Portal” will tell you about the features of the equipment so that you can choose an effective, reliable and safe single- or double-circuit gas boiler for heating your home from the whole variety of these devices.

To understand which unit is best for an apartment or house, you must first study the types of gas heating boilers.

1. By material: cast iron, steel, copper.
2. By location: wall and floor.
3. By type of combustion chamber: open and closed.
4. By the number of circuits: single-circuit and double-circuit.
5. According to the presence of additional functions, automation, external characteristics.

Let's look at the types of gas boilers in more detail.

Heat exchanger material

It is worth choosing the internal heat exchanger of heating equipment very carefully, since liquid circulates inside it, and a powerful flow of thermal energy moves outside. Therefore, the heat exchanger material must have good thermal conductivity, on which the efficiency of the device depends, and at the same time a high safety margin.

Manufacturers install heat exchange coils in gas boilers made from:

• cast iron;
• of stainless steel;
• copper

At first glance, a boiler with a cast iron heat exchanger is the most reliable, since it is the least susceptible to corrosion. However, such units are very heavy, and very often, due to non-compliance with the rules of operation of the device, the cast iron heat exchanger cracks in the contact zone of the liquid with a very different temperature. This type of device requires more frequent cleaning.

In this regard, many homeowners choose to connect a steel heat exchange coil. Stainless steel devices are cheaper than copper and cast iron units. In addition, steel is very ductile, so the likelihood of cracks occurring in areas with temperature changes is much lower. However, such heat exchangers, being in the heating circuit, quickly corrode.

Thus, the most reliable choice is a copper heat exchange device. Copper has the best heat transfer rate, is highly resistant to corrosion processes, has good ductility, and is light in weight. Copper heat exchange coils are very compact, but the high price of such devices forces one to choose less reliable, but cheaper units.

Heat exchangers also differ according to the type of internal structure: conventional and bithermal. In the first case, it means connecting only one liquid circulation circuit, and in the second case, you can connect two water circulation circuits at the same time. Double-circuit boilers are equipped with two conventional heat exchangers or one bithermal coil, which is much more economical.

Combustion chamber and burner type

Heating is impossible without maintaining gas combustion using indoor or outdoor oxygen. In the first case, the heater package contains an atmospheric burner for natural circulation of air flows, and in the second case, the device is equipped with a closed burner with forced oxygen injection. In this regard, the consumer can choose a gas boiler for the home with one of two types of combustion chamber:

1. Open - to maintain the combustion process in the firebox, air comes directly from the boiler room or room where gas equipment is installed.
2. Closed - oxygen for the combustion of the flame is taken from the street using additional ventilation or a chimney designed according to the “pipe-in-pipe” principle.

If we choose between a closed firebox with a turbo burner and an open chamber with an atmospheric burner, then it is worth understanding that an open combustion chamber will require the installation of a chimney of 5-7 meters to ensure natural draft, which is not always possible. Therefore, each individual case requires an individual approach.

Wall and floor models

Everything is very clear here - floor-standing gas boilers for heating a private house can only be installed on the floor, since their dimensions, weight and power are much greater than those of a wall-mounted gas boiler, which is used when space is limited. Wall-mounted gas heating boilers are usually installed in the kitchen of an apartment building.

At the same time, installing a gas boiler in an apartment requires compliance with certain installation standards, which are much stricter than when installing a gas boiler in a private house.

1. Wall-mounted appliances have a relatively small power, which averages 35 kW, since wall-mounted boilers are equipped with a copper heat exchange coil that cannot withstand too high temperatures.
2. Gas floor units are the optimal choice of heating device for a private home, since such equipment can easily heat a building with an area of ​​up to 700 sq. m. There are even outdoor models that can be installed outside a residential building.

Floor-standing double-circuit or single-circuit devices, depending on the configuration of the batch, can be equipped with a turbocharged or atmospheric burner. A distinctive feature of turbocharged models is their high efficiency and high safety margin, while a unit with an atmospheric burner is more durable and less noisy, and their cost is lower.

Single- and double-circuit gas boiler

Considering the types of gas heating equipment, one cannot help but note their differences in the number of circuits.

A single-circuit gas boiler for heating a private house in its standard configuration is used only for heating the building, and floor-mounted or wall-mounted double-circuit devices, in addition to heating premises, also supply hot water to water intake points.

In order for a single-circuit gas boiler for heating private houses to also perform the functions of double-circuit devices, you can additionally connect a boiler. But it’s still better to immediately use a double-circuit gas boiler for heating houses.

Connection diagram for a single-circuit unit with a boiler:

There are also significant differences in the design of these types of heating gas equipment.

The double-circuit wall-mounted one is much more compact than its single-circuit counterparts, so they are the best option for a small room with a lack of free space. At the same time, such models put forward higher requirements for operating conditions.

Since dual-circuit devices heat water in the system, to automatically turn on the hot water supply, it is necessary that the flow of incoming water has good pressure and therefore the consumption of hot liquid increases significantly.

In addition, the double-circuit floor option is not very suitable for large areas if the water intake points are too far from the liquid heating device. This feature of dual-circuit equipment is due to the fact that in this case an additional circulation pump cannot be connected.

Single-circuit devices also have design features that affect the operation and installation of gas equipment. First of all, it is worth noting the large dimensions of such units, as well as the labor-intensive process of installing a gas boiler in a private house.

Moreover, if a boiler is included in a single-circuit system, it can be equipped with an additional circulation pump, which will supply hot water to several water intake points - shower, kitchen, sink, however, the efficiency of such single-circuit heating equipment is limited by the volume of the boiler, and the cost of the system increases.

Which device is better to choose for your home?

The selection of a gas boiler for a private home largely depends on the area of ​​the room and other factors.

The technical documentation for a gas heater certainly covers information about the requirements and rated power of the device. Often the manufacturer indicates the area of ​​the room that this boiler can heat, as well as instructions on how to install the unit.

When making calculations, an experienced heating engineer should take into account:

• cubic capacity and area of ​​the room;
• climate of the region of residence;
• quality of external thermal insulation of walls; the number and size of windows, as well as what type of double-glazed windows are installed in them;
• the presence of balconies and street doors;
• heating system data, etc.

In addition, it is necessary to take into account the quality of the fuel and the gas pressure in the line. A separate calculation must be made for the DHW system. And only after that both figures are summed up, and then increased by 15-20% for a margin so that the boiler can cope with peak and constant load.

There are a lot of characteristics for choosing a gas boiler, but the main ones are:

1. Output power of the equipment.
2. Layout device (number of circuits, material from which the heat exchanger is made, type of housing).
3. Installation location.
4. Is there automation for safe operation of the equipment?
5. Price. Not always a cheap option of poor quality.

All these points are interconnected. If there is no space for installing a large unit or the desire to install a device in the kitchen whose appearance will be in harmony with the interior of the room, one is forced to opt for a wall-mounted model, whose power is much less compared to a floor-standing device. And if it is necessary to heat hot water, they are forced to buy double-circuit equipment.

The best models of gas boilers

Nowadays, the market offers a wide range of this equipment in various price categories - from fairly cheap Chinese-made products, which are of rather dubious quality, to boilers with turbocharged combustion chambers and other technical bells and whistles from branded manufacturers, but the price of such devices is also quite high.

There are several types of gas boilers, so when choosing equipment for your home, you need to know exactly what you need.

1. Vaillant atmoVit INT 164-564/1-5 is the best device for a home with an area of ​​50 to 150 m2. Cost 81,000 – 100,000 rubles.
2. Bosch WBN6000-18C RN S5700 is the optimal dual-circuit model for a building with an area of ​​100 to 180 m2. Price 36,000 – 43,000 rubles.
3. Viessmann Vitopend 100-W type A1JB 12 kW - the best price-quality ratio in a double-circuit condensing version for buildings with an area of ​​up to 120 sq. m. Viessmann cost 35,000 - 41,000 rubles.
4. Ferroli Divatech F24 D is the optimal option for heating and hot water supply to buildings with an area of ​​100 to 240 m2. Price 40,000 – 45,000 rubles.
5. BAXI SLIM 1.490 iN is the best single-circuit unit for heating a private house from 200 to 300 m2. Cost 70,000 - 78,000 rubles.
6. Buderus Logano G334WS-73 is an ideal model for a home with an area of ​​more than 300 m2. Cost 315,000 - 350,000 rubles.
7. Protherm Bear 30 KLOM is the best floor-standing Protherm model with an open burner, for buildings up to 260 m2. Price 49,000 – 55,000 rubles.
8. Irbis Khoper 25 SABC is the most budget-friendly unit with acceptable build quality for buildings up to 250 sq. m. Cost 33,000 - 36,000 rubles.

These companies have been presenting their products on the market for a long time and their quality has been tested by a huge number of customers. Although domestic equipment (Irbis) is inferior in ease of use and performance characteristics to devices manufactured by foreign companies, they perform their main task properly.

The temperature characteristics of all models are not very different. All boilers comply with all safety standards and norms, but more expensive models have a complex multi-stage self-diagnosis system, as well as fairly effective automatic protection. The service life and reliability of equipment are characterized by the quality of assembly and parts, and, of course, compliance with all requirements and operating standards.

Installation rules and subtleties

The site’s consultants recommend strictly following the rules for installing a gas boiler. To install such equipment in a home, you must obtain permission. This opportunity will only appear after a number of the following conditions are met:

• the room must be equipped with good ventilation and a source of natural light, which will be required for servicing the equipment;
• in the boiler room, the ceilings must be at least two and a half meters, the room area must be at least 4 m2, the doorway must be at least 80 cm wide;
• The power supply system must be equipped with current and thermal protection. The choice of a voltage stabilizer for gas boilers is a separate point that requires separate consideration and must be given sufficient attention;
• The width of the chimney directly depends on the power of the boiler. For example, the power is about 30 kW, then the chimney diameter should be at least 13 mm;
• presence of pressure and temperature sensors;
• It is prohibited to install gas equipment in basements;
• The gas pipeline must not be laid in fire hazardous areas;
• regardless of the type of gas pipeline (closed or open), the pipes for it must be metal;
• The boiler room must have a gas level analyzer, as well as an electric valve, which, if necessary, will shut off the gas supply.

Helpful advice! To install a gas boiler, as well as to complete all the necessary documentation, you need special tools and professional skills. If you have neither one nor the other, then the best solution would be to contact an organization that deals with this.

If you have decided to independently replace your old heating equipment with a new one, then it is best to do this in the following sequence:

• flush the old heating system. If the pipes are clogged, this will significantly reduce the life of a new boiler, even of very high quality, so it is recommended to use a special compressor to remove blockages and contaminants. If it is impossible to clean the pipes, then simply replace them with new ones;
• dismantle old equipment;
• install new equipment, taking into account all the recommendations in the boiler operating instructions;
• connect the boiler to the smoke exhaust system. If the house does not have its own chimney, then it is better to purchase a coaxial chimney. The equipment instructions usually indicate the requirements for the characteristics of the chimney. This is a rather important point, since due to the insufficient width of the chimney or its low height, most of the combustion products will enter the room;
• The boiler must be connected to the gas pipeline. You won't be able to do this with your own hands. This is carried out only by organizations that have the appropriate permission;
• the unit crashes into the heating system and the PVA system;
• commissioning work is being carried out. They are a fairly important point during installation, since the future efficiency of both the boiler itself and the entire system depends on them.

To install a new gas boiler you will need to perform the following steps:

• check the presence of all components - they should include a mounting template, a strip for connecting gas and water, the necessary pipelines and the boiler itself;
• select a level to secure the hanging bar, then attach it;
• install gas and water pipeline gaskets by removing protective plugs;
• install the boiler itself, then connect the water circuit and gas supply system to it;
• Connect the power supply and equipment to the chimney.

Particular attention should be paid to voltage drops. Which voltage stabilizer is best for a gas boiler depends on the power model of the equipment itself.

Thus, before choosing a gas boiler for a private home, you need to determine the requirements for its functionality. For houses where there is a boiler or a water heater, purchasing a double-circuit boiler will be an irrational decision, due to the unnecessary waste of money, but if there is a need to equip a hot water supply, a double-circuit gas boiler for heating a house will be the optimal solution.

Gas is most often used to heat a private home; this fuel is beneficial for residents of Russia. Since heat generators are expensive, you need to know how to choose them correctly. The review describes the best floor-standing gas boilers, taking into account price and technical characteristics.

Which floor-standing gas boiler is better to buy?

Floor-standing boilers are able to operate autonomously and regardless of the availability of electricity. If you choose a model with a cast iron heat exchanger, it will last more than thirty years. Powerful equipment heats a large area without any problems, but its price is much higher.

Mechanical models can be easily repaired in case of breakdown, while electronic models provide comfort in operation. When choosing the best floor-standing gas boilers, it is recommended to choose the following models:

• Among single-circuit devices, the Baxi Slim230 iN is most often chosen. The equipment has a modern design, compact dimensions and the highest efficiency.
• The most popular boiler with a water heating tank is Buderus Logano G124 WS-32.
• Lemax Premium-30B is considered the most reliable double-circuit boiler. It heats a large area using fuel economically.

Due to the fact that a large number of new, modified models of domestic and foreign production with different characteristics and price levels have appeared in the range of heating devices offered to consumers, nowadays it is possible to replace an old boiler with a more economical, compact and aesthetic one without any problems. Many owners decide to “kill two birds with one stone” with such a purchase, that is, at the same time solve the issue of autonomous supply of hot water. And now this is not difficult - they are offered a wide selection of double-circuit boilers.

However, such high market saturation often contributes to the “reverse effect”, that is, it makes choosing the optimal model a very difficult task. We will try to help with this - we will provide a list of devices that are consistently included in the constantly changing rating of double-circuit, wall-mounted and floor-mounted gas boilers. True, a reservation can be made: the authors deliberately did not award certain places to the listed boilers - simply so as not to interfere with the subjective factor in this issue. The determining criterion was the positive feedback from consumers who had already tried this technique in practice. In a word, the boiler models indicated in the publication can be purchased with close to 100% confidence in receiving a device of high build quality and with the expectation of its long-term operation.

Of course, when choosing any heating boiler, you need to pay attention to other criteria that affect quality and durability.

Basic criteria for choosing a heating device

Double-circuit boilers are divided into floor-mounted and wall-mounted.

• Floor-standing double-circuit gas boilers, as a rule, are designed for higher thermal output than wall-mounted models, so they are most often installed in houses with a large area. However, for such heating devices with a power of 30 kW or more, a separate room from the living area is required. Therefore, before choosing such a model, it is necessary to study not only the technical characteristics and operating rules, but also the standards for boiler room equipment.

On sale you can find models of floor-standing gas boilers that do not require power to operate - it is only important that a gas supply with natural or liquefied gas is provided. Such variants of units are especially convenient for heating in houses located in rural areas, where power outages are not uncommon. The design of non-volatile boilers is quite simple, but very reliable; such units are more durable than boilers with complex automation.

The efficiency of modern floor-standing models is 90 percent or higher.

• Wall d Double-circuit gas heating devices, as a rule, are compact in size, so they are convenient to install in small houses or even in a city apartment.

Since such a unit does not take up much space, it is usually placed on the kitchen wall, where all the communications necessary to connect it are located. For the operation of almost all models of wall-mounted heating devices, an uninterrupted power supply is required. The circulation pump, the automation unit, and, in models with a closed combustion chamber, the fans for air injection and exhaust of combustion products require power.

Naturally, installing a gas boiler in the living area of ​​the house increases the requirements for organizing a more efficient ventilation system.

Unlike floor-standing boilers, in which steel or cast iron heat exchangers are often installed, wall-mounted units, in order to reduce their weight, are often equipped with copper heat exchange elements.

The power of wall-mounted units usually varies from 9 to 30 kW.

Power of double-circuit boilers

In order for a heating and water heating device to be truly effective in operation, it is necessary to correctly calculate its power for a specific house or apartment.

Very often on the Internet you can come across a sign like this:

To be honest, such information, instead of a clear idea, can, on the contrary, raise a lot of questions in the consumer. Agree that the difference in price between 9 kW and 20 kW models will be quite significant, and the spread of options according to such a “coordinate system” is impressive.

In addition, this approach does not take into account the characteristics of the regional climate, the building itself and its individual rooms, the degree of glazing (that is, the number and size of windows) and many other important circumstances. Therefore, it seems more reasonable to carry out more thorough calculations, in which the calculation calculator located below can help.

The basic principle is that calculations are carried out for each heated room separately, and then the results are summed up. This, by the way, gives the owners another “preference” - having such calculation results in hand (and it is best to display them on a plate - for each room separately) it will be much easier and correctly to arrange heat exchange devices in the rooms - radiators or convectors.
