The best gas boiler

A comparison of gas boiler equipment was carried out according to the following characteristics: design (wall-mounted, floor-mounted), functionality (number of circuits), gas combustion chamber (open, closed), gas consumption, m3/h, average cost.

In the nomination for the best floor-standing heating boiler, Baxi Slim 2300Fi received more votes. Double-circuit, with a closed combustion chamber. The power of the device is 29.7 kW with a gas flow of 3.49 m3/h. The average cost is 44 thousand rubles.

Advantages of the device: built-in 50 liter water heating tank, electronic indication and piezo ignition, multi-level security and self-diagnosis system.

The main disadvantage of the device is its high cost.

The Baxi Luna 3 comfort 240 Fi received the palm in the category for the best wall-mounted heating boiler. This is a dual-circuit device with a closed combustion chamber, with a power of 25 kW. Gas consumption at this performance is 2.84 m3/h. Cost 25 thousand rubles.

Main advantages: full adaptation to the peculiarities of the domestic gas supply, the ability to program for 7 days, a diagnostic system and multi-level protection, the presence of authorized service centers.

Disadvantages of the device: relatively high cost and sensitivity of the electronics to changes in mains voltage.

Due to the fact that the range of heating devices offered to consumers has included a large number of new, modified models domestic and foreign production, having different characteristics and price levels, in our time 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, installation gas boiler in the residential 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.

Unit power in wall-mounted version 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.

Heart of Autonomous heating system– hot water boiler. Both the air temperature in the house and the amount of heating costs depend on its quality, functionality and efficiency. In order not to make a mistake in choosing this important device, it is necessary to study every detail and function of the device. The rating of wall-mounted gas heating boilers will help you save time on getting familiar with the equipment - the top positions in it are always occupied by equipment that has earned the trust and recognition of other users.

Classification of gas boilers

Lightweight and compact wall-mounted gas heating boilers are suitable for autonomous systems in individual cottages and city apartments. This group combines several types of equipment that differ fundamentally in terms of design and operation. Here is a list of the most important design features, which you should pay attention to before choosing a boiler:

1. Number of circuits: single-circuit ones are focused only on heating, and double-circuit ones provide hot water supply functions in parallel.
2. Combustion chamber type: open or sealed (closed).
3. Exhaust gas removal method: natural or forced.
4. Energy dependence: non-volatile wall-mounted gas heating boilers operate without being connected to electricity.
5. Burner type: atmospheric or modulating with automatic power control.

Consumer ratings: independent choice of buyers

The best condensing boilers

Condensing boilers are more expensive, but the overpayment is more than compensated by economical gas consumption and high efficiency of heat generators, amounting to at least 95-98%. It is believed that the best wall-mounted gas heating boilers of this type are produced by the German company Viessmann.

Taking the lead in the condensing appliance segment is the compact and elegant Viessmann Vitodens 100-W with a maximum output of 35 kW and a hot water preparation speed of 14 liters per minute.

Device ViessmannVitodens 100-W

The second position in the ranking is occupied by the single-circuit Ariston Clas Premium Evo System 35 FF, adapted for low gas pressure. The device is equipped with a primary copper heat exchanger and a secondary plate-type steel heat exchanger. The maximum power of the device is 35 kW.

On the third line is the German Bosch Condens 5000 FM heat generator, which supports operation in a cascade and with solar collectors. The device is equipped with electronic control of the composition of the gas-air mixture and a unique heat exchanger with patented tube configuration technology.

Two in one: the best models of dual-circuit heat generators

Combination boilers solve two important problems at once: they heat the house and provide it with hot water. These devices are in demand among owners of individual buildings and apartment residents who do not want to depend on centralized hot water supply.

The Vaillant turboTEC PRO VUW with forced exhaust of flue gases and a built-in plate water heater with a capacity of 11.5 liters of hot water per minute earned the most positive reviews in this group. The device is equipped with a closed combustion chamber and a modulating burner. The efficiency of the device is 93%, power is from 8 to 24 kW.

Second place in the ranking is occupied by the Italian Baxi Main Four 240 F, capable of preparing 13.7 liters of hot water per minute. Gas wall-mounted boilers Baxi heating systems are equipped with a closed chamber. The devices have traction control sensors, a thermostat to prevent water overheating, and protection against freezing and scale.

In third place is the German Bosch ZWA 24-2A with an efficiency of 95% and a water heating rate of 11.4 liters per minute. The device easily copes with servicing a house with an area of ​​up to 240 square meters. meters. The compact boiler is equipped with a three-stage circulation pump and an eight-liter expansion tank.

The Neva Lux 7218 double-circuit gas boiler was not included in the top ten, but it can be noted as one of the most affordable devices. The device is equipped with a biothermal heat exchanger, modulating burner, electronic control and LCD display. The domestic boiler is aimed at heating a house with an area of ​​up to 180 square meters. meters.

Five leading manufacturers of wall-mounted water heating boilers

The manufacturer plays an important role in the selection of boiler equipment. 70% of consumers are willing to overpay for a brand if its name is associated with product quality.

The first position in the customer trust rating is occupied by Viessmann - a reputable German manufacturer energy saving equipment. Wisman condensing wall-mounted gas heating boilers are equipped with a simulated burner that maintains combustion when the gas pressure is insufficient.

In second place is Protherm, a manufacturer of high-quality and functional equipment at an affordable price. The range of heat generators of this Slovak brand includes several lines of devices with open and closed combustion chambers and a wide power range.

In third place in the ranking of wall-mounted gas boilers is the leading European manufacturer of equipment for boiler rooms, Wolf. In assortment German company models with different combustion chamber designs, with built-in heat exchangers for hot water and the ability to connect a boiler.

The fourth place went to the German leader Buderus. The Logamax series of wall-mounted boilers is aimed at Russian consumers and is suitable for operation under conditions of gas and water pressure differences.

The top five most popular manufacturers among Russian users is closed by the Italian company BAXI, whose product range includes single-circuit and double-circuit wall-mounted gas heating boilers, including economical condensing boilers.

The most attractive in price

Wall-mounted gas heating boilers of domestic production are recognized as the most affordable in the line functional models. Among Russian manufacturers, the leader is EPO Signal, whose assortment includes 4 modifications of double-circuit devices of the Angels series. Angels boilers are equipped with a burner with electronic ignition and an automatic ionization-type flame control system.

In the middle price range are Korean wall-mounted gas heating boilers of the Navien brand, represented by groups of high-quality double-circuit appliances with separate and coaxial system smoke removal units that operate uninterruptedly under conditions of low and varying gas and water pressure.

Wall model NAVIEN DELUXE

Daewoo is another Korean giant that supplies the market with inexpensive atmospheric models and economical boilers with a closed combustion chamber. For ease of control, the devices are supplemented with remote controls and liquid crystal indicators.

The assessment of a group of consumers may not always coincide with personal opinion, so we recommend considering not only the models that received the most votes, but also other devices from well-known manufacturers, as well as new products that have not managed to win the trust of customers. In order not to make a mistake with the choice of durable equipment, it makes sense to seek help from a specialist who will take into account the needs of the family and the real capabilities of the existing heating system.

Choosing the best boilers - rating of double-circuit wall-mounted gas boilers

With the start of the heating season, the owners country houses The question often arises about which heating boiler is worth purchasing. This article is devoted to an overview of the most popular double-circuit gas boilers. The rating of double-circuit wall-mounted gas boilers was compiled for wall-mounted models from Baxi, Protherm and Navien.
We considered models that were similar in price category and technical characteristics with a power of about 20 kW and these were the following models: Main Four 24 F (Baksi), Gepard MTV 23 (Proterm) and Ace 24k (Navien).

Model Manufacturers

The Italian manufacturer Baxi is in great demand on the Russian market. Almost all regions of the country have service centers repairing equipment. Models are assembled and parts are produced in the brand’s homeland and in a number of European countries. Models with a capacity of 18-24 kW are supplied to the Russian market.

The Slovak manufacturer Protherm is known and distributed in all regions of the Russian Federation. The service network of this manufacturer is also widely represented in all major regions of Russia. The company produces boilers on its own territory; components are produced in Slovakia and Germany. The range of models imported to Russia is 11-23 kW.

The Korean manufacturer Navien was introduced to the world relatively recently, but thanks to its practical design and affordable cost, boilers from this manufacturer quickly became popular. The production of parts and assembly of boilers is carried out directly in South Korea.

A very wide range of models with a power of 10-40 kW is supplied to Russia.

Design of compared models

The boiler from Baksi is a boiler based on a bithermic heat exchanger and the ability to automatically switch to DHW supply mode. The design includes a circulation pump, expansion tank volume 6 liters, safety sensors. All connections are cast from copper. The coolant is heated by a heat exchanger alternately in two circuits.

The boiler from Proterm has a copper heat exchanger for the primary circuit and a second steel heat exchanger for the DHW circuit. A three-stage control valve is provided to switch operating modes. It is also equipped with a German circulation pump and a 5-liter expansion tank, and safety sensors.

The connections, like those of Baksi, are cast from copper. An important difference between this model and the previous one is the presence of a second heat exchanger, which ensures independent heating of water for heating and the hot water system.

The boiler from Navien is also equipped with two independent heat exchangers, but both of them are cast from steel. Let us remember that the previous model had one of the heat exchangers made of copper. A steel heat exchanger is much more reliable than copper.

All built-in equipment - circulation pump, expansion tank, sensors and valves are manufactured directly in South Korea.

Technical parameters of models

The chimney of all the models under consideration is made according to the coaxial scheme. This means that the same pipe has two compartments, through one of which air is introduced into the boiler, and through the other, exhaust gases are removed.

Dimensions of the tested models (HxWxD, cm):

• Baksi 73x40x29.9
• Proterm 74.2x44x26.5
• Navien 72.2x44x26.5

Heating capacity of models (kW):

• Baxi from 9.3 to 24
• Proterm from 9.0 to 24
• Navien from 9.3 to 24

Volume of produced hot water (l/min)

All models are capable of heating an area of ​​up to 220 m2.

Model functionality

To compile a rating of double-circuit wall-mounted gas boilers, all compared boilers have the ability to adjust the burner and the function of maintaining the temperature in a separate heating circuit. In addition, all models have frost protection.

Models from Baksi and Proterm provide the ability to connect a room temperature sensor and an outside temperature sensor, thanks to which you can implement the climate control function.

Baksi, unlike other models, has a “warm floors” mode, and the Navien model has a remote control unit. In addition, the Navien boiler is protected from power surges.

Cost of models

Protherm 600 euros

Navien 500 euros.

Having analyzed the parameters of the boilers according to the indicated parameters, it is easy to conclude that the rating of gas boilers was distributed as follows:

3rd place. Baxi Main Four 24 F

2nd place. Proterm Gepard MTV 23

1 place. Navien Ace 24k

To compile the rating, this article examined the 3 most popular and similar models of gas boilers wall installation with two circuits: Baksi Main Four 24 F, Rotherm Gepard MTV 23 and Navien Ace 24k.

There are several types of gas boilers, and therefore, when choosing a model for your home, you need to know exactly what you need. Let's briefly go through the classification of each type of heating equipment:

Single-circuit and double-circuit

Single-circuit gas boilers in the basic configuration are used exclusively for heating the room, while double-circuit gas boilers, in addition to heating the home, are also responsible for supplying hot water.

It is worth noting that, if desired, you can additionally purchase a boiler for a single-circuit boiler, and then it will be able to perform all the functions of a double-circuit boiler.

In respect of design features These types have significant differences: double-circuit boilers are much more compact, which makes them an ideal option for rooms with limited free space, but they are also more demanding in terms of operating conditions. A double-circuit boiler heats running water, and in order for the DHW system to automatically turn on, the flow of incoming liquid must have high pressure, as a result of which saving hot water is practically impossible.

Also, double-circuit boilers are not the most the best solution for large rooms, where water intake devices - taps, showers, etc., are very distant from the boiler itself. This is due to the fact that a heating system based on a double circuit cannot be equipped with an additional circulation pump.

Single-circuit boilers also have their own characteristics, including large sizes and labor-intensive installation. When using a boiler, systems based on single-circuit boilers can be supplemented with circulation pumps to supply hot water to several water intake points, however, the efficiency of such a system is limited by the volume of the boiler.
It is also worth noting that the total cost of a system consisting of a single-circuit boiler and a boiler is higher than the price of a double-circuit boiler.

Floor and wall

Everything is simple here - floor-standing boilers are installed exclusively on the floor - they have much larger dimensions and power than wall-mounted counterparts, which make sense to use only in cases of limited free space.

As a rule, the power of most wall-mounted boilers is limited to 35 kW, as they have a copper heat exchanger that cannot withstand high temperatures.

Floor-standing boilers are the best option for heating rooms with an area of ​​150 to 600 sq.m. Depending on the configuration, floor-standing boilers can have either an atmospheric or a turbocharged burner. A distinctive feature of atmospheric burners is endurance, noiselessness and high price, while boilers with turbocharged burners have an order of magnitude greater efficiency, but are also significantly more expensive.

The best gas floor heating boilers

Having dealt with the classification of modern gas boilers, we move on to compiling a rating. To do this, we analyzed numerous reviews from owners of a wide variety of boilers and identified the best models in each class of heating equipment.

Single-circuit gas heating boilers

Boiler in the kitchen

Every year at the end of the year, thermal equipment specialists sum up interim results and prepare analytical reviews. They help to understand what was most in demand on the market in the past year, and which manufacturers’ products were able to win the sympathy of buyers. Of particular interest is the rating of gas double-circuit boilers compiled in this way, the list of the most popular models and the explanation of why they were included in the list of the best heating equipment.

The market notes stable demand for wall-mounted gas double-circuit boilers of the new generation. These are improved options, equipped with modern automation and a reliable security system. Almost every company uses innovative solutions. They made it possible not only to replace existing series, but also to offer new unique examples of technical art.

The main trends of this season

Technology today has reached a level where it can control some parameters of its work without human presence. That's why modern manufacturers gas double-circuit boilers - wall-mounted and floor-mounted - great attention this year we paid attention to caring for the environment, as well as improving systems that reduce energy consumption.

The focus was also on ways to increase plant efficiency. Many units had modernized burner designs. Many manufacturers took into account the peculiarities of Russian communications, so series adapted to our realities appeared on sale. These are gas heating boilers in the form of floor-mounted and wall-mounted options that do not respond to pressure surges within the network and turn off if the gas or water supply is interrupted.

Another newfangled trend is moving away from piezo ignition and giving preference electronic ignition. Today, many floor-standing gas double-circuit boilers do not have a pilot burner. Even budget models differ in a full range of functions characteristic of a particular brand. Therefore, they have LCD screens, built-in weather-dependent automation, and precise control over all processes occurring inside the boilers.

The shift in supplier geography deserves special attention. If several years ago the ranking of the most popular manufacturers was headed exclusively by European concerns, today South Korean brands and domestic companies have joined their ranks.

Recognized leaders

Germany

In the elite category heating technology The ranking of the most popular models is still headed by the Germans. The leaders are Bosch, Buderus, Vaillant, Viessmann and Wolf. A wide range of models allows you to choose products taking into account the individual characteristics of autonomous heating systems. Almost all German heating equipment is characterized by high quality workmanship, extreme reliability, compactness and stylish design.

During operation, gas wall-mounted and floor-standing boilers make virtually no noise. They are easy to operate, easy to install and can operate even with low gas pressure and minimal water volume.

Boiler room Viessmann

But German boilers also have disadvantages, which manufacturers continue to work on eliminating:

• Among the assortment on the Russian market, it is difficult to find models that allow heating private houses or apartments with an area of ​​more than 300 square meters. m.
• The described heating equipment takes a long time to warm up. It takes more than a minute for it to start dispensing hot water.
• Anyone who purchases German gas wall-mounted double-circuit boilers is forced to spend some time servicing them. And all because chimney ducts often become clogged.

Otherwise the technique is impeccable.

Italy

Italian brands are in second place among European manufacturers. Many people are familiar with such brands as Ariston, Baxi, Ferroli, Nova Florida and Saunier Duval. All products are on average price segment. Therefore, it is more accessible to the general population. Acceptable price and high quality - features Italian products. The vast majority of the range consists of double-circuit wall-mounted gas boilers designed for the assembly of autonomous heating systems and hot water supply lines.

Baxi LUNA-3 COMFORT 240

The list of advantages of “Italians” is as follows:

1. A special approach to production allows us to achieve high quality. Entrepreneurs spend a lot of effort and time on improving the qualifications of their staff. Therefore everyone technical unit assembled by the hands of highly skilled workers.
2. Every year, part of the profits is invested in scientific developments. So production is constantly modernized and expanded, which makes it possible to produce interesting new products that attract the attention of potential buyers. At the same time, each specific market is studied very carefully, and changes are made to production schemes taking into account its characteristics.
3. A huge range allows you to choose an Italian gas boiler for a specific room, house or apartment.
4. Baxi and Ferroli boilers have a self-diagnosis system. This is the latest know-how in the production of the described heating equipment. Other brands boast a simple and reliable control system, extremely convenient for daily use.
5. Italian boilers do not overuse fuel and operate even with a sharp drop in gas pressure and at very low atmospheric temperatures.

It is possible to install boilers without allocating space for heating equipment separate room. In cramped conditions, compact dimensions play a big role. Italian heating equipment is installed quite quickly, but there is one BUT. Its installation can only be entrusted to specialists licensed to install wall-mounted and floor-mounted double-circuit gas boilers.

France

Chaffoteaux Alixia 24 FF

French manufacturers close the top three. Brands such as Chaffoteaux, Chappee, De Dietrich and Frisquet rely on three components - reliability, durability and high quality. They are doing everything to ensure that these three aspects become the flagships of production.

French manufacturers of gas wall-mounted double-circuit boilers have been present on the domestic market since 1996. During this time, not only branded sales offices were opened throughout the country, but also service centers offering high-quality service for the products described.

Over the past decades, France has been able to present several high-profile premieres demonstrating great innovative potential. Therefore, French manufacturers managed to stay in the ranking of the most sought-after and popular brands. But the Polish brand Termet, the Slovak brand Protherm and Electrolux from Sweden have long been hot on their heels.

Asians

Recently, Korean brands have also become more active. The concerns “Celtic”, “Daewoo”, “Kiturami” and “Navien” have long been trying to win the sympathy of consumers. The Navien trademark received the title “Breakthrough of the Year” this year. Korean gas double-circuit boilers are very reliable, versatile and fit well into autonomous heating schemes.

The Navien concern has chosen the field of innovative design of thermal equipment as its main strategic direction. This allowed him to launch the production of wall-mounted double-circuit boilers of a new generation with exceptional technical characteristics.

Let us outline the main ones:

• Korean gas wall-mounted boilers are very compact and safe to use.
• They demonstrate high operating efficiency in conditions low temperatures, which is very important for the Russian climate.
• The stability of operation is not affected even when the gas and water pressure drops to a minimum.
• They are not afraid of power surges either.
• The presence of an automatic system eliminates the possibility of defrosting the boiler.

Note! The presence of intelligent filling allows the boiler to adapt to existing weather and independently set the necessary operating modes. The boiler will always function economically and efficiently, and for this you do not need to constantly look after it.

Convenience, ease of use, the ability to use the latest scientific developments and not overpay for them - this is what allowed Korean gas double-circuit boilers to quickly gain space in the market and stand on a par with the products of the listed European manufacturers.

In fairness, it is worth noting that Russian manufacturers, for example, Gazapparat, AZGA and Signal have strengthened their positions in the market. They are also capable of competing, but for now they help set up large heating systems for residential areas and country towns, shopping centers and production workshops.

A little more analytics

Ferroli Pegasus DK

Speaking about the main trends of the outgoing year, it should be noted that modern manufacturers are concerned not only with preserving environment and the search for new energy-saving technologies, but also the opportunity to increase the efficiency of double-circuit wall units. Therefore, today you can find double-circuit boilers with a power of more than 30 kW on sale.

The German concern Vaillant was the first to launch such models - the power of its products is 36 kW. Then the Italians distinguished themselves, and the Frisquet brand offered a series of wall-mounted boilers with a capacity of 45 kW. South Korean Daewoo offered a model whose power was increased to 40 kW.

The boom in flow-through heat exchangers is gradually passing. Today, a series of wall-mounted double-circuit boilers are more popular, the package of which can include storage boilers. This tandem turned out to be more convenient and practical. Ferroli and Frisquet, Hermann and Nova Florida, the German Viessmann this year released wall-mounted boilers with a built-in microboiler, the volume of which does not exceed 4 liters.

Large capacity for storing hot water was offered by Ariston and Baxi, Beretta and Biasi. As well as Buderus, Chaffoteaux, Chappee and Ferroli.

Significant changes have also occurred in smoke removal systems. South Korean and Japanese brands have proposed using gas outlets of larger sizes than those of European manufacturers. Now you can see the diameter of the gas outlet pipe 70/100 and 80/110 versus 60/100 standard.

Generalization

Ferroli Diva F16

As you can see, a large number of technical innovations were presented this year. It was they who created the demand, allowing some manufacturers to maintain their leading positions in the competition, and others to burst into the ranking of the most popular and in-demand heating equipment on the crest of technical progress. The leaders are still Germans, but the Asians have long been treading on their heels. It’s nice that domestic manufacturers were able to attract the attention of potential buyers.
