Manufacturers of gas wall-mounted double-circuit boilers

The Italian company Baksi is perhaps the most popular on Russian market brand of gas boilers. We have been selling boilers for a long time. They have a wide network of service centers throughout the country. Reviews are different because there are a lot of them for sale.

The company claims that it delivers its boilers only from Italy, as evidenced by the barcode on the packaging of the boiler. However, lately the warranty card attached to the product, for some reason, has been written entirely in Ukrainian. In our market, only models with a capacity of 18 and 24 kW are presented.

The products of the Slovak company Proterm are also widely used in Eastern Europe, including Russia. Proterm is a subsidiary of a German manufacturer of high-quality gas and electric heating equipment, however, their gas boilers are in a higher price category, and today we will not consider them.

You can draw some parallel between these companies. Speaking in “automobile language”, then Protherm for Vaillant is like Skoda for Volkswagen. I think motorists will understand me. Almost the same, only cheaper.

The barcode on the package from the boiler indicates the country of origin - Slovakia. The Gepard MTV boiler line is represented only by models with a thermal power of 11 and 23 kW.

The Navien company is a holding company consisting of several Korean companies. Main direction: gas and diesel boilers for heating. The correct spelling of the company name is Navien. In fact, this is an abbreviation that stands for "Navigator Energy".

Gas wall boilers Navien are produced only in South Korea and are also supplied from there. The Navien gas boiler reviews, which can often be found on the Internet, are in great demand, mainly due to the very attractive price at which the products of this company enter the Russian market. Wide the lineup boilers Navien Ace is presented with a capacity of 10 to 40 kW.

The device of double-circuit wall-mounted gas boilers

The double-circuit wall-mounted gas boiler Baxi Main Four 24 F consists of a copper bithermic heat exchanger and an automatic bypass for switching to hot water supply mode, a circulation pump German company, expansion membrane tank 6 liters, safety group, including an overpressure relief valve, draft sensor and flame control. All supply pipes are made of copper.

The water in the boiler is heated by a bithermic (one) heat exchanger, which works in turn on two circuits: heating and flow utility water. When the DHW mode is turned on, the heating circuit switches to the domestic water heating mode in the bithermic heat exchanger.

Boiler Baxi Main Four 24 F


The double-circuit wall-mounted gas boiler Protherm Gepard 23 MTV includes a copper primary heat exchanger for the heating circuit, secondary plate heat exchanger for hot water supply, made of stainless steel, a three-way valve for switching the operation of circuits made in Germany.

The Grundfos brand pump for coolant circulation is installed the same as that of Baxi. 5 liter expansion tank, draft and flame sensors. Copper inlets.

An important difference between the device of the Cheetah boiler and Baxi Mine is the presence of a secondary heat exchanger for hot water in the Slovak model.

The double-circuit wall-mounted Ace also has two separate heat exchangers (heating and hot water), but unlike the Cheetah boiler, both heat exchangers are made of stainless steel, which significantly increases their service life.

Another distinctive feature of the Navien boiler device is that the built-in equipment - heat exchangers, pump, expander, three-way and safety valve, as well as sensors are made in South Korea.

Coaxial chimney for gas boiler, forced draft device

All models have been designed coaxial chimney for gas boiler. What it is?
means a pipe-in-pipe chimney. The combustion products are exhausted through the internal channel, and air is supplied to the boiler through the external channel.

But in some cases it is necessary to make a separate chimney, i.e. separate pipe for exhaust, and separately for air intake. To do this, you can additionally purchase a channel separator or the so-called “pants” for models from any manufacturer.

However, Korean manufacturers specifically offer the Navien Ace model with already separate smoke exhaust and inflow. This is very convenient, allows you to save on the purchase of an adapter.

And in conclusion, I will share one interesting video recall

The heart of the autonomous heating system- hot water boiler. 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 save time on getting acquainted with the technique - 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 are fundamentally different from each other in terms of the principle 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 are focused only on heating, and double-circuit in parallel provide hot water functions.
  2. Type of combustion chamber: 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 paid off by economical gas consumption and high efficiency heat generators, constituting at least 95-98%. It is believed that the best wall-mounted gas heating boilers of this type are manufactured by the German company Viessmann.

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

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

On the third line is the German heat generator Bosch Condens 5000 FM, which supports operation in 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 a patented tube configuration technology.

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

Combined boilers solve two important tasks at once: they heat the house and provide it 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 most positive reviews in this group were Vaillant turboTEC PRO VUW with forced withdrawal flue gases and a built-in plate water heater with a capacity of 11.5 liters of hot water per minute. The device is equipped closed camera combustion and modulating burner. The efficiency of the device is 93%, power is from 8 to 24 kW.

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 the maintenance of a house up to 240 square meters. meters. The compact boiler is equipped with a three-stage circulation pump and an eight-liter expansion tank.

The double-circuit gas boiler Neva Lux 7218 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 focused on heating a house with an area of ​​​​up to 180 square meters. meters.

Five leading manufacturers of wall-mounted hot water boilers

Not the last role in the choice of boiler equipment is played by the manufacturer. 70% of consumers are willing to overpay for a brand if its name is associated with product quality.

  1. Viessmann

The first position in the customer confidence rating is taken by Viessmann, a reputable German manufacturer of energy-saving equipment. Wismann condensing wall-mounted gas heating boilers are equipped with a simulated burner that maintains combustion with insufficient gas pressure.

  1. Protherm

In second place is Protherm, a manufacturer of high-quality and functional equipment at an affordable price. The model range of heat generators of this Slovak brand includes several lines of devices with an open and closed type combustion chamber 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. The assortment of the German company includes models with a different combustion chamber arrangement, with built-in heat exchangers for hot water and the ability to connect a boiler.

  1. Buderus

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 in conditions of gas and water pressure drops.

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

Most attractive price

Wall-mounted gas heating boilers of domestic production are recognized as the most affordable in the line of functional models. Among Russian manufacturers, EPO "Signal" is the leader, in the assortment of which there are 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 there are Korean wall-mounted gas heating boilers of the Navien brand, represented by groups of high-quality double-circuit devices with a separate and coaxial smoke removal system, which operate smoothly in 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 consumer group may not always coincide with a personal opinion, therefore 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 possibilities of the existing heating system.

Video: how to choose a gas boiler

Each time, when choosing heating equipment, the question arises not only of choosing the characteristics of the model, but also of the manufacturer, on which the quality sometimes directly depends. This also applies to the gas heat generator. The market offers many models of various price categories, from which it is not always easy to choose a gas boiler that meets all expectations. To simplify the choice, as well as save time searching for a quality product, there is a reliability rating for gas boilers.

gas boilers

For a general idea, you need to consider the classification of gas heating equipment that exists on the market:

  1. According to the method of natural gas combustion and removal, there are units with an open combustion chamber and a closed one.
  2. According to the efficiency of using the heat of combustible natural gas, there are convection boilers and condensing boilers. The second type saves fuel consumption by about 15-20%, moreover, it has a higher efficiency compared to a traditional boiler.
  3. According to the ability to heat water for the needs of hot water supply: single-circuit and double-circuit.

The first type is designed for space heating, often installed in rooms without water supply, while the second type is designed for heating and hot water supply. A double-circuit boiler saves space, but not the amount of water. In addition, it is demanding on operating conditions and equipment. A double-circuit gas boiler can be made from a single-circuit gas boiler by attaching a boiler to it. However, in this case, the volume of water supply will be limited by the capacity of the boiler, moreover, such a system will cost more than a compact two-circuit system.

By installation, boilers are wall-mounted, or suspended, and floor-mounted.

The first type is used for installation in limited areas. The floor boiler is larger, but also more powerful, designed to heat a large area up to 600 sq.m. The wall analog has a power of 35 kW and is designed for heating buildings up to 100 sq. m, since the copper heat exchanger will not withstand a higher temperature.

  1. Classification of models by power.

After the choice regarding the characteristics has been made, you can proceed to the choice of a manufacturer offering quality equipment.

Rating of gas boilers in terms of reliability and quality


Floor boiler

Rating of single-circuit and double-circuit

Among single-circuit and double-circuit gas boilers there are none that would not meet modern requirements for efficiency and safety.

In choosing a gas boiler for heating country house sometimes it’s not its technical characteristics or price that are decisive, but the reviews of those people who have already bought a boiler and, on their own experience, appreciated all its advantages and disadvantages.

You can find reviews directly in stores that sell boilers, but according to popular opinion, the most truthful opinions and useful advice are on thematic forums. It was they that the author of the article took advantage of, after analyzing the most popular forums and, based on them, ranking the best gas heating boilers of 2017.

It should be noted that it is impossible to make an overview of all gas heating boilers within the framework of one article, therefore, the comparison was made only among double-circuit wall-mounted heating boilers, as the most popular among the population of our country.

The following were taken as evaluation criteria:

  • Reliability, for the evaluation of which is used guarantee period manufacturer
  • The ability to connect to natural and bottled gas (many owners of private houses, while waiting for connection to the main gas, are forced to use LPG for heating for several years)
  • Number of heat exchangers. The boiler with two heat exchangers is considered the best. The fact is that when water is heated, scale forms in the heat exchanger, which can lead to its failure. If there is only one heat exchanger, there is a great risk of being left without heating. if there are two of them, then you will have to give up hot water for a while, but at the same time the second heat exchanger will provide the house with heat.
  • the presence of built-in additional equipment (pump and expansion tank)
  • Automatic control system
  • Type of combustion chamber
  • Boiler weight

Boiler in the kitchen

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

The market notes a stable demand for wall-mounted gas double-circuit boilers new generation. These are improved options, equipped with modern automation and reliable system security. 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 the level where it can control some of the parameters of its work without the presence of a person. Therefore, modern manufacturers of gas double-circuit boilers - wall-mounted and floor-standing - paid great attention this year to caring for the environment, as well as improving systems that reduce energy consumption.

Also, the focus was on the possibility of increasing the efficiency of the installation. Many units have upgraded 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 and wall options that do not respond to pressure surges within the network and turn off in the event of a gas or water supply failure.

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

The shift in the geography of suppliers deserves special attention. If a few years ago the rating of the most popular manufacturers was headed exclusively by European concerns, today South Korean brands and domestic companies have wedged into their ranks.

Recognized Leaders

Germany

In the category of elite heating equipment, the rating 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 heat engineering is characterized by high workmanship, special reliability, compactness and stylish design.

During operation, gas wall 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.

Viessmann boiler room

But German boilers also have disadvantages, on the elimination of which manufacturers continue to work:

  • 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 heat engineering takes a long time to warm up. It takes more than a minute to start dispensing hot water.
  • Anyone who purchases German gas wall-mounted double-circuit boilers is forced to spend some time on their maintenance. And all because chimneys are often clogged.

The rest of the technique is flawless.

Italy

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

Baxi LUNA-3 COMFORT 240

The list of advantages of "Italians" is as follows:

  1. To achieve high quality allows a special approach to production. Entrepreneurs spend a lot of time and effort on staff development. Therefore, each technical unit is assembled by highly skilled workers.
  2. Every year, part of the profits is invested in research and development. So the production is constantly being 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 carefully studied, 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 particular 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 heat engineering. Other brands boast a simple and reliable control system that is extremely convenient in daily use.
  5. Italian boilers do not waste fuel, they work even with a sharp drop in gas pressure and at very low atmospheric temperatures.

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

France

Chaffoteaux Alixia 24 FF

Closes the top three French manufacturers. Brands such as Chaffoteaux, Chappee, De Dietrich and Frisquet rely on three pillars - reliability, durability and high quality. They are doing everything to make 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 have opened throughout the country, but also service centers offering 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, Slovak trademark Protherm and Electrolux from Sweden.

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

Concern "Navien" has chosen the area of ​​innovative design of thermal equipment as the main strategic direction. This allowed him to establish the production of a new generation of wall-mounted double-circuit boilers with exceptional technical characteristics.

Let's name the main ones:

  • Korean gas wall-mounted boilers are very compact and safe to use.
  • They demonstrate high performance at low temperatures, which is very important for the Russian climate.
  • The stability of work is not disturbed even when the pressure of gas and water drops to a minimum.
  • They are not afraid of voltage drops in the mains.
  • Availability automatic system eliminates the possibility of defrosting the boiler.

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

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

In fairness, it should be noted that Russian manufacturers, for example, Gazapparat, AZGA and Signal, have strengthened their positions in the market. They are also able to compete, but so far they help to establish large heating systems for residential areas and suburban villages, shopping centers and production shops.

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

The German concern Vaillant was the first to launch such models into production - 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 has proposed a model whose power has been increased to 40 kW.

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

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

Significant changes have also taken place in smoke exhaust systems. South Korean and Japanese brands have suggested using gas outlets that are larger 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.

As you can see, this year technical innovations were presented a large number of. It was they who formed the demand, allowing some manufacturers to maintain their leading positions in the competition, and others to break into the rating of the most popular and sought-after thermal equipment on the crest of technical progress. The Germans are still the leaders, but the Asians have been on their heels for a long time. It's nice that domestic producers were able to attract the attention of potential buyers.
