Overview of baxi gas wall-mounted boilers. Baxi ultra-compact gas boilers - main, slim, four models. Main models and their prices
The arrangement of the heating system of a large country house or apartment is a complex and expensive task. First you need to carry out all the necessary calculations, then purchase the main element - the boiler.
The modern market offers Russian consumers products of different brands, which produce dozens of models that differ in the type of design, technical characteristics and other parameters. The Italian plant also presents its products - the Baxi gas boiler, which has a number of advantages.
Briefly about the company
Baxi is a brand from Italy that has been manufacturing heating and hot water equipment for over 50 years. The company offers users a wide range of its products: classic wall-mounted and condensing gas boilers, floor-standing units with a cast-iron heat exchanger, electric water heaters. These are modern high-quality and reliable products that meet all regulatory requirements.
At the moment, the company produces about half a million units of gas boilers in one year, including the popular series: Luna, Main, Slim. Since 1993, when the company received the ISO 9001 quality certificate, its products have been highly rated by consumers.
BAXI S.p.A. founded in 1924 by the Austrian Westen family. The company began producing gas boilers between 1978 and 1984, when it was part of the Zanussi group. Since 2009, the company has been part of the BDR Thermea group, its boiler plant is the center of the holding. The total annual output is about half a million wall appliances.
Features of Baxi boilers
We are talking about high-tech equipment with excellent basic characteristics. At the request of buyers, additional elements can be included in the package, which will make the device even more functional.
The manufacturer offers the following devices:
- Timer. Wall and floor boilers "Baksi" can be programmed in such a way that they work at the time specified by the user. Thanks to this approach, the price of heating is reduced: when no one is at home, the equipment will automatically turn off.
- Room thermostat. This accessory is essential for indoor climate control. Its use is very simple - the desired temperature is set on the display, and the heating device independently maintains it. When the desired value is reached, the device will turn off. When the temperature drops by one degree, it will start working again.
- Outdoor temperature sensor. Thanks to this element, the boiler will be able to respond to weather changes. The technology is needed to maintain the optimum temperature in the house, while reducing gas consumption.
Thanks to these accessories, the final cost of heating is reduced, and home heating becomes many times more efficient. In addition, these elements will facilitate the operation of the device.
Advantages
Among the wide variety of heating equipment, a worthy place belongs to the Italian company Baxi. If we compare the gas equipment of this company with the products of other companies, it becomes clear that the models of this brand are the most technologically advanced and functional. At a minimum, they can be used not only for the purpose of heating, but also for the preparation of hot water. That is, this is a 2 in 1 device. The brand's catalog contains many models that have minor differences in technical parameters.
Among the advantages of Baksi units are the following:
- Electric ignition. One minute is enough to heat the boiler, and the minimum power is used for this. As soon as the equipment is ready, it starts working at maximum.
- Automatic flame power adjustment. Thanks to this, a comfortable temperature will always be maintained in the room. It also has a positive effect on the life of the device, because constant on-off often become the main reason for the failure of devices.
- post circulation system. To do this, the equipment is supplemented with special accessories that reduce the consumption of electricity and gas.
- Easy installation. Floor or wall installation is possible. The device itself has a solid and reliable design, despite its low weight.
- Environmental friendliness. During the operation of the plant, when the fuel burns, a minimum amount of carbon dioxide is released into the air.
Heating equipment has proven itself well when working in premises for various purposes: from country cottages and apartments to industrial buildings. Due to the fact that gas boilers are able not only to heat housing, but also to prepare hot water, they make life much more comfortable. This property is especially important if a person lives in an area remote from centralized engineering networks.
Flaws
If we consider the negative qualities of Baxi gas equipment, we can only highlight its high cost. It is explained by the quality of the products. You need to understand that heating equipment is an important element on which the comfort of living will depend. Therefore, experts do not recommend saving on the purchase of a quality unit.
Some types of appliances must be installed in a specially designated room - a boiler room, which must be properly prepared. If there are no skills in working with gas boilers, then their installation should be entrusted to specialists.
Prices for the range of Baxi gas boilers
gas boiler Baxi
Types of units by type of heat exchanger
Devices are single- and double-circuit. The former are able to heat water only for the heating system, while the latter can serve as a flowing geyser. Accordingly, different heat exchangers are installed in them.
Primary
Such elements are always tubular, they look like a monometric device located under the burner. This copper component is responsible for heating the coolant.
Primary elements are installed only in single circuit boilers, but they are not as common as double circuit units due to the small difference in cost.
All Baxi heat exchangers are made of high quality materials - copper and brass. They provide special processing, which makes them reliable and gives high physical characteristics.
Secondary
They are lamellar heat exchange surfaces. Energy transfer is carried out by means of sanitary water. The elements got their name because of their shape - these are stainless steel plates combined with each other.
The secondary heat exchanger is needed for the boiler to work both for heating and for the DHW system (hot water supply).
Bithermic
These copper elements operate on the "pipe in pipe" principle. They are designed to heat the coolant for the heating system and hot water. They heat water efficiently, but they definitely require that the coolant be of high quality. If the liquid is supplied with a lot of impurities, then thin pipes quickly become clogged, as a result, the efficiency of the boiler is reduced.
Types of boilers according to the method of removal of combustion products
The fuel is burned in a special chamber, which can have a different design. For each type of boiler, the furnace has its own characteristics, on which the efficiency and conditions for using the unit depend, namely, the place of its installation.
Turbocharged
All boilers require oxygen to operate. In such units, a forced draft fan is responsible for the air flow. Compared to other boilers, turbocharged ones require a special chimney consisting of two pipes: air enters through one, and smoke is removed through the second.
Often, units of this type are used in conditions of insufficient free space, where it is not possible to equip a classic chimney. A distinctive feature is that turbocharged boilers are produced with low power - up to 35 kW, which is explained by the presence of a copper chamber, which requires gentle operation.
atmospheric
This type of boiler is suitable for houses with a chimney with a diameter of more than 130 mm. The chamber here is open, and combustion products are removed naturally. Often this type of device is called "aspirated".
The flue pipe of the Baxi boiler has a diameter of 121–122 mm, therefore, an aluminum corrugation with a diameter of 125 mm can be used as a pipe. This element is not afraid of high temperatures (up to + 400 ° C) and easily stretches up to 3 meters. An alternative option is to install a stainless steel chimney, but this will cost a little more. The design of the atmospheric unit does not provide for the installation of a turbine.
Varieties of wall-mounted boilers "Baksi"
Based on the name, it becomes clear that these units are mounted on the wall. There are no strict requirements for the installation process of the equipment. The boilers are easy to operate and have a large power reserve. Several types are produced.
Condensing
A certain part of the generated energy of such boilers leaves with water vapor. But here it is necessary to take into account the moment that the formed steam condenses. In order for this process to start, the combustion products must be cooled to a temperature of + 55 °C. This function is performed by the water inside the boiler. It cools the combustion products and then enters the system. For condensing boilers, there are certain requirements for the amount of temperature heating of the coolant.
Compared to traditional units, condensing units achieve savings of approximately 11%. Products are not only economical, but also environmentally friendly - they can be installed even in residential premises. They work almost silently.
With one circuit
This type of boiler heats only the water that circulates through the heating system. If desired, the unit can also be connected to a hot water supply, but this will require an indirect heating boiler.
When buying such a boiler, you need to take into account the volume of the chamber, based on the number of people living in the house. Units from "Baksi" with one circuit have a power parameter from 14 to 31 kW, which is quite enough to warm up a country house with an area of \u200b\u200bno more than 400 m 2.
With two circuits
Double-circuit installations are in demand if you need to prepare hot water in a short time. Heating the liquid does not affect the operation of the heating system. A key feature of boilers with two circuits is the presence of two heat exchangers. One is copper, which transfers heat from the unit to the radiator. The second prepares domestic hot water and is created from plates.
The heat exchanger that heats the water is a secondary element. Water is supplied to it as needed. Models with different types of heat exchange elements are produced.
Heating boilers are technically complex devices, in order for the equipment to serve for a long time, you need to know how to properly handle it. The package of delivery of each model without fail includes an instruction, which indicates recommendations for installation and safe operation.
The Baxi brand produces several lines of boilers and, in order not to overpay, you should first determine the required power and volume of heated water. If pressure drops occur in the system, this must be taken into account, not to mention other operational features.
For example, it makes no sense to buy an expensive and high-power unit for heating a small house. For such cases, the Baxi ECO Four model is suitable. If you're looking for a small yet powerful rig, the Nuvola 3 is worth a look.
In the selection process, you need to pay attention to the following criteria:
- Power. To do this, you need to know the area of \u200b\u200bhousing and divide this figure by 10.
- Energy dependence. More expensive models do not depend on the availability of electricity. Of course, the issue with the supply of electric current can be solved by installing an uninterruptible power supply.
- Presence of water heating. Then you need to buy a two-circuit unit.
- Boiler type according to the place of installation. Floor standing and wall mounted units available.
- heat exchanger material. To increase the service life, it is better to purchase a boiler with copper or stainless steel elements. There are also cast-iron heat exchangers, but they are quite fragile and heavy, but they perfectly resist corrosion.
- Type of heating system. Centralized or autonomous.
- Compliance of the chimney and combustion chamber.
You can deal with these issues yourself, but with a lack of knowledge and experience, it is recommended to contact a specialist who takes into account all possible nuances. Buying a Baxi gas boiler is not a problem if you know which model is needed.
Possible problems and malfunctions
So far, the world has not invented an ideal technique that would not fail. If the Baxi boiler does not work as it did before, this may indicate some kind of malfunction. As a rule, minor problems are solved on their own, because taking the boiler to a service center is not an easy task. If the skills are not enough, it is better to immediately call the master at home.
List of common problems and how to solve them:
- The power of the flame in the burner has decreased. Most often, this situation occurs when the pressure in the system is incorrectly adjusted. Another reason is the gas valve modulator or diode bridge is broken. To get rid of this problem, you need to correctly configure all system parameters, following the instructions supplied with the boiler, or replace damaged components.
- Switching off the boiler immediately after starting. The problem occurs when the pressure in the gas pipeline is low. It is solved by adjusting the gas pressure down - 5 mbar.
- The coolant is badly heated. It is necessary to check the pressure parameters on the gas valve. Most often, this problem occurs if the min and max values \u200b\u200bare lost.
- Modulation failed. The valve will need to be replaced.
- Temperature sensors are wrong in the values. Old elements are replaced by new ones.
- Insufficient hot water heating. The malfunction may be caused by incomplete opening or breakage of the three-way valve. To verify this, you need to wait until the system has completely cooled down. Further, the valve is closed and the boiler is switched on to the DHW mode. If the element is defective, then the heating system will heat up.
- During ignition, "pops" are heard. This situation arises for two reasons: there is insufficient pressure in the system or the distance between the gas supply and the igniter has changed. The situation is solved by adjusting the gap, the optimal value is from 4 to 5 mm. To perform this work, the boiler cover and damper are removed, behind which the igniter is located. Next, the screw holding the electrode is removed and carefully bent.
- The fluid temperature in the circuit has dropped. As a rule, this happens due to clogged filters. So they need to be cleaned. Sometimes radiators or damaged pipes can be the cause. It is necessary to prevent freezing and clogging of the system.
These problems occur most often, but, as practice shows, you can cope with them on your own. Of course, this will require certain skills. Boilers "Baksi" are fully automated, and they have a self-diagnosis system. Therefore, during operation, the corresponding icons and error numbers may be displayed on the display of the device, indicating a particular malfunction.

Baksi gas boilers - user reviews
“... I would like to note that Baxi boilers are an expensive pleasure. For example, an average device from Baxi will cost at least 25,000 rubles. We are talking about the Baxi Fourtech 240 Fi boiler. This is a wall-mounted model that can run on natural gas and is supplied with two circuits. Mounted on the wall by hanging.
As for power, the maximum power of the boiler is 24 kW, that is, the Baxi Fourtech 240 Fi model can heat 240 m2 with a ceiling height in the room not higher than 2.7 meters. And now criticism towards Baxi boilers. All Baxi models require annual maintenance. Many sellers at least position this idea very strongly.
In addition, boilers are explosive (according to reviews on the forums), and this is a real phenomenon, especially if you miscalculate the cubic meters of the room. Of course, about explosiveness - this statement is not only true for Baksi boilers, but also for other boilers. Also, many complain about noise and spontaneous shutdown ... "
Anatoly Georgievich, Balashikha.
“... To keep warm in my house (the second floor is 50 m2, and the first floor is 100 m2), I chose the Baxi Luna-3 Comfort 240Fi gas heating boiler. I installed it more than three years ago, and I am 100% satisfied with the purchase. I chose for a very long time - after going to forums and shops, after viewing reviews and collecting opinions about these boilers from people who have been operating this model for a long time.
One thing is clear - indeed, I had to talk a lot with company managers (more than ten) and review a lot of messages on the forums before I decided to buy the Baksi boiler after all. As mentioned above, I am completely satisfied, the house is warm, and I practically don’t look into the boiler - I just wipe it from time to time ... ”
Maxim, Dolgoprudny.
“…Our family recently purchased a Baxi Main Four 240Fi boiler. It was recommended to us by friends who have been using this particular model for 5-6 years. No shortcomings have been noticed so far, but everything that has become much more economical and comfortable was felt by everyone at once. Our house is quite large, and it was rather problematic to heat it with an old coal-fired boiler.
Everyone just suffered - it was necessary to get up early to melt the boiler, it was impossible to leave for a long time, and so on. Once they already changed the frozen cast-iron radiators, so they decided to change the heating system to gas heating. Now we really feel free and confident…”
Oksana, 38 years old, Moscow region.
“... My wife persuaded me for a long time to buy autonomous heating, and I resisted to the end, but she won. I was afraid that either the gas would be turned off, or something else would happen - the 90s scared us so much. But still, I made up my mind. First, it was necessary to choose the right model of the boiler.
After long, but informative consultations and visits to various stores, we chose the Baxi 24 F, like our friends. At first, we became interested in the dimensions of the boiler, but this model had more than compact ones, and we no longer doubted it. This model has been working for six years, and for all the time the problems did not manifest themselves in any way ... ”
Osipov Nikolai Petrovich, Podolsk.
Baksi gas boiler is a modern and reliable heating and water heating device manufactured by one of the largest manufacturing companies in Europe. The high quality of equipment under the BAXI brand is the result of a successful combination of advanced technologies with many years of development and experience gained by a foreign company.
Model range of boilers Baxi (Baksi)
The range of the Italian manufacturer BAXI is represented by dozens of efficient models that operate using natural gas or solid fuel. All wall-mounted and floor-type heating equipment differs in size, design and power ratings, but has international quality and ISO certificates, therefore it is absolutely safe in terms of operation.
Condensing
Condensing equipment is considered environmentally friendly and energy efficient
The most significant advantages of condensing equipment are represented by its complete environmental friendliness and energy efficiency. The fundamental difference between condensation is the use of a reserve of thermal energy in the form of water vapor, which is formed during the combustion process and is again converted into a liquid. Thanks to this feature, the energy consumption of the equipment is reduced, and the amount of toxic substances emitted is also reduced.
Among the wall-mounted condensing models, noteworthy are the series that have flexible adaptability to performance characteristics, including the features of the chimney design, composition and type of gas:

floor standing
Floor standing boilers are usually installed in boiler rooms
A design feature of modern floor-standing gas boilers with an atmospheric burner is the possibility of non-volatile operation of some series of equipment:
- SLIM is a popular series with power from 15 to 62 kW. The system performs self-diagnosis, and ease of maintenance is ensured by electronic modulation of the flame. Price range - 102,000–214,000 rubles;
- SLIM HPS - a series with a sectional cast iron heat exchanger and excellent aerodynamic properties. The minimum heat loss is due to the fiberglass thermal insulation under the casing. Price range - 255,000–341,000 rubles;
- SLIM EF - non-volatile series with automatic closing of the gas valve. Models of this series have a power in the range of 22–61 kW and a stylish design in gray and black tones. The price range is 87,000–142,000 rubles.
Floor boilers are relevant for heating rooms with a large area (from 180–200 m 2) and, as a rule, are installed in a specially equipped boiler room. The main advantages of such models include high power and decent performance.
Reviews
According to users and experts, equipment under the BAXI brand has proven to be reliable and durable, unpretentious in maintenance, of decent quality and easy to operate, with flexibility of settings, and is characterized by almost silent operation. Consumables for repair work are always available at major service centers.
However, despite the intuitive clarity and simplicity of the interface, there are a number of parameters that should be set by specialists when commissioning the equipment. Among other things, negative reviews are received by the instability of the temperature of the hot water supply and the strong cotton that accompanies the ignition of the device.
The device of a double-circuit gas boiler Baxi
Baksi gas equipment based on Grundfos or Wilo circulation pumping equipment has an expansion membrane tank of a built-in type, is equipped with a Noneywell gas valve and a reliable safety group in the form of an automatic air vent and a safety valve device with a pressure gauge.
The device of a double-circuit boiler Baksi
The equipment consists of 25 main units
As "smart" elements in the equipment, temperature control of the DHW circuit, flame and draft, as well as a protective system that prevents the boiler from freezing and blocking the circulation pump, is used.
Connection and setup
Connection and adjustment of any gas equipment is carried out in accordance with special requirements:
- installation of the boiler at the selected location;
- chimney connection;
- supply and connection of water through the filter;
- connecting the boiler to the electrical network through a stabilizer.
Commissioning works:
- disconnection of the boiler from the power supply;
- checking the pressure in the expansion tank and stabilizing the indicators to a level of 0.5 atmospheres;
- checking heating taps and transferring them to the "Open" mode;
- filling the heating system to one and a half atmospheres and shutting off the tap;
- bleed air in heating batteries until the pressure drops and re-set to the “Unit” indicator or a little more on the pressure gauge;
- bleeding air with a screw on the pump under the panel;
- short-term inclusion of the boiler in the "Heating" mode at minimum temperatures.
After a couple of minutes, the boiler is turned off by the button on the panel and from the power supply, after which the pump screw opens and all the air is vented. The screw is left open about a quarter of a turn, which will allow the system to bleed air on its own. Then you should turn on the "Heating" mode and check the heating of the batteries.
Brief instruction manual
Proper regulation of the temperature regime of the coolant directly affects the efficiency of gas consumption. The basic configuration of the boiler assumes, as a rule, independent temperature control, but if necessary, the equipment can be easily supplemented with weather-dependent automation.
The most important operating parameters:
- clocking - the frequency of turning on the equipment, which is three minutes by default. In the absence of external control devices, the maximum clocking mode is 10 minutes. More frequent switching on is uneconomical, and setting this parameter in specific models requires studying the instructions;
- economy mode is set by the minimum parameters of maximum and minimum useful power. The minimum modulation range of boiler equipment for 24 kW is 40%, and for heating a room with an area of 80–90 m 2, 9 kW is enough;
- most modern models of Baksi boilers have the ability to connect a room thermostat, which allows heating if the air temperature drops below the specified parameters;
- connection of a programmable thermostat allows for flexible adjustment of different temperature regimes during the day, and lowering the temperature by one degree throughout the year allows you to save fuel by 4–5%.
If necessary, you can use the system of zone temperature control in different rooms by means of individual controlled thermal heads. In this case, gas savings are about 30%. Among other things, the result of the accumulation of soot and scale inside the system is a decrease in heat transfer performance, so competent maintenance is a guarantee of economical and trouble-free operation of the boiler.
Common errors and malfunctions
At any stage of the functioning of the heating equipment, malfunctions may occur, the notification of which is carried out by means of coded errors.
Error | Reasons for the appearance | Solutions |
Starting the boiler is impossible and is accompanied by a drop in coolant pressure | Connection errors of phase-dependent equipment | Reconnect the boiler bleeding air from the system and topping up the coolant |
The burner does not operate at full capacity | Pressure setting errors, malfunction of the diode bridge or valve device | Replace faulty units, correct settings in accordance with the user manual |
Boiler shutdown immediately after start-up | Low pressure indicators of the main gas, errors in setting the lower limits | Check the stability of the gas supply, set the lower value to 5 mbar |
Traction deterioration | Errors in the installation of the chimney and fan, condensate in the chimney malfunction of the pneumatic relay, broken contact between the relay, the board and the fan |
Eliminate the listed causes |
Low temperature of the thermal carrier | Incorrect gas valve setting | Adjust gas valve |
Modulation violation | Failure of the board or gas supply valve | System testing, board or valve board replacement |
Erroneous readings of temperature sensors | Failure of one or several sensors at once | Replacement of defective sensors |
A sharp decrease in the temperature regime inside the heating circuit | Use of low-quality coolant, blockages in radiators or pipes, clogged filters | Eliminate blockage, fill the system with high-quality coolant |
Of course, along with other brands of gas equipment, boilers under the BAXI brand are not without some drawbacks, but their undeniable advantages are full adaptation to Russian climatic conditions, a long service life, a wide range of models, ease of maintenance and regular updating of all technical documentation.

At the same time, in the series POWER HT 230-320 power increased even more, up to 320 kW. Such boilers are suitable for heating large buildings, for example, office or shopping complexes. High durability is achieved through the use of silumin heat exchanger.
Slim boilers and Slim HP have a cast-iron heat exchanger and an atmospheric burner. Power range ranging from 15 to 62 kW. And in Slim HP There is also fiberglass insulation under the shell to keep heat loss to a minimum.
All the above (and other) boilers can be found in the category:.
If the article was useful, as a thank you use one of the buttons below - this will slightly increase the ranking of the article. After all, it's so hard to find something worthwhile on the Internet. Thank you!wall Baxi gas boilers literally flooded the Russian market of heating equipment over the past decade. This is not surprising. When a potential buyer faces a choice: to buy an inexpensive boiler, but unfinished and domestic, or a reliable, but expensive German-made boiler, the choice is often made in favor of Italian gas boilers.
As a rule, they are distinguished by a fairly good price-quality ratio and a developed maintenance network, it is easy to find spare parts. Consider the most popular brand of Baxi gas boilers in Russia, reviews of which we can often read on specialized forums, Internet blogs or on the company's official website.
We will analyze in detail the main models, types, device, technical characteristics of wall-mounted (mounted) single-circuit and double-circuit gas boilers Baxi, identify their main advantages and disadvantages, and also understand how they differ from each other according to the operating instructions.
The main models of Baxi wall-mounted gas boilers
The following models of wall-mounted gas boilers from Baxi are presented on our market:
- Baxi Main Four and (fourth and fifth generation of boilers);
- Baxi Four Tech and Baxi Eco 4S;
- and its more compact counterpart Baxi Eco Compact;
- Baxi Luna-3 and Luna-3 Comfort with remote control panel;
- Baxi Nuvola-3 with built-in storage boiler.
Baksi wall-mounted gas boilers differ in the type of combustion products removal and are:
1. Turbocharged gas boilers Baxi with a closed combustion chamber
A special fan (turbine) is installed in the boiler, with the help of which the combustion products from the boiler are forcibly removed into the atmosphere. To do this, you will have to additionally buy, or a pipe system for separate smoke exhaust and air flow.
The coaxial type of chimney of the "pipe in pipe" type is installed with one end (through the elbow) on the boiler, and the other end goes out through the wall. This is very convenient, because there is no need to specially block the chimney through the roof.
Gas boiler Baxi Main Four 240 Fi
Such models at Baxi are designated by the article "F" or "Fi". For example, mounted double-circuit gas boilers Baxi Main Four 18 F, Baxi Eco 4S 24F or Baxi Eco Four 24 F. The numbers indicate the power of the boiler, i.e. 18 or 24 kW.
2. Atmospheric boilers Baxi with an open combustion chamber
If your private house already has a chimney with a diameter of at least 130 mm, then you can buy a boiler with an open chamber, the emission of combustion products of which occurs due to natural draft. Such boilers are often called "aspirated".
On the Baxi boilers themselves, the diameter of the flue pipe is 121-122 mm, so an aluminum corrugation with a diameter of 125 mm is suitable for them, capable of withstanding temperatures up to 400 degrees Celsius, which can be stretched up to three meters. Alternatively, stainless steel flue pipes of the same diameter can be used. True, this version of the chimney will cost a little more.
These models do not have a turbine, and the article “i” is present in the labeling of the Baksi boiler, or it is not affixed at all. For example, "Baxi Eco Four 24i" or "Baxi Four Tech 24".
Baxi wall-mounted gas boilers are available in two versions:
1. single circuit.
This type of boilers provides only for heating the coolant in the heating system. These boilers have only one main heat exchanger. This type of boiler is not very popular, because its cost is slightly lower than for double-circuit models.
In turn, a wall-mounted double-circuit gas boiler can always be used only for heating, and the second circuit for hot water supply should not be connected at all.
You can simply buy a Baksi double-circuit gas boiler, even if there is no running water for the future. After all, it is possible that after some time the second circuit of this boiler will come in handy, and you will not have to buy a new device.
2. Dual circuit.
Such boilers are most popular with buyers, as evidenced by the numerous reviews of Baxi gas boilers. They are able to work both as a heating unit and as a flowing geyser. Moreover, while using running hot domestic water, the heating of the heating circuit does not turn on automatically, unlike many brands of floor-standing gas boilers.
Double-circuit wall-mounted gas boilers have two separate heat exchangers, or one bithermic one for heating both circuits in one monolithic block. Boilers of this type are most in demand among potential buyers. Having bought such a boiler, we get in “one bottle” both a boiler for heating and for hot water supply.
Features of the device of double-circuit gas boilers Baxi: instructions
Double-circuit boiler Baxi Eco 4S 24F
1. All models are equipped with two separate heat exchangers (except for the Main Four and Main 5 series boilers) for heating water in the heating system and domestic, flowing for hot water supply. The main heat exchanger is made of high-quality copper, the secondary one for hot water supply is made of stainless steel.
2. All boilers are equipped with a circulation pump from German manufacturers, either Grundfos or Wilo. This pump is able to raise the water column in the heating system up to 6 meters, which is quite enough for a two-story house or cottage. The circulation pumps built into the boilers are quite economical and equipped.
3. To maintain the required pressure in the heating system, Baksi boilers have a built-in membrane expansion tank with a volume of 6-10 liters. You do not need to buy an additional one more if the total volume of water in the system does not exceed 100-150 liters. This individual volume can also be found out independently by counting the total number of radiator sections, the length of the pipe, or when filling the system.
4. Baxi boilers are equipped with a Honeywell gas valve, the gas burner has stainless steel flame spreaders. All models automatically maintain the temperature of the water in the heating system and in the DHW circuit thanks to the smooth electronic modulation of the burner.
The boiler safety group includes:
- automatic air vent;
- safety valve with pressure gauge.
Consider the device of a double-circuit gas boiler using the example of the Baxi Eco Four 24F model according to the scheme:

In addition, an electronic board is built into the wall-mounted boilers, the so-called. The "brains" of the boiler, various sensors: flow, temperature of the DHW and heating circuit, as well as draft and flame sensors. There is a system for protecting the boiler from freezing and blocking the circulation pump. Which does not cancel the mandatory purchase for a boiler of this brand.
Baksi gas boilers: model differences and technical specifications
As you can see, the range of boilers from this Italian manufacturer is quite wide. Let's now take a closer look at each of the main models, and find out how they differ from each other and what features they have.
Features of models of boilers of the Baxi Main Four and Baxi Main 5 series
The predecessor of the boilers of this series were devices called Baxi Main, which did not have an LCD display and a number of other functions. In general, the word "Main" in translation from English means "main" or "main". Also in our case, the boilers of the “Main” series are the basic version of the wall-mounted gas boiler from Baxi.
Their main distinguishing feature is the presence of a bithermic heat exchanger. This means that both the heating circuit and the DHW circuit are heated in the same heat exchanger. The water in the circuits does not mix, and the running water is heated precisely by the heating circuit.
The fifth generation boiler attracts with its compact dimensions, but is produced only with a closed combustion chamber, unlike the fourth generation boiler. They can be used for heating a private house or apartment with an area of up to 200-240 m2, they have a model range with a capacity of 14, 18 and 24 kW.
Specifications Baxi Main 5
Features of the Baxi Eco Four and Baxi Eco Compact boiler models
The main feature of these models is the presence of an additional stainless steel plate secondary heat exchanger for heating the DHW circuit.
The main (primary) - heats water only in the heating circuit, and the secondary one works independently of it, using the coolant from the heating circuit to heat running water. Thus, the load on the main heat exchanger is noticeably reduced. Thus, the service life of both it and the gas boiler itself is increased.
Model Baxi Eco Compact already in its name indicates to us its small dimensions, due to the better arrangement of internal elements, compared with the same boilers of the fourth series. In addition, they are equipped with a new electronic board. The "ancestors" of the Eco Four series boilers are wall-mounted gas boilers of the third Baxi Eco 3 Compact series.
Specifications Baxi Eco Four
Features of models of gas boilers Baxi Four Tech
Series boilers are a cheaper version of Eco Four series boilers. They are also equipped with two separate heat exchangers made of copper and stainless steel. Their distinguishing feature is that the hydraulic part (water supply pipes) is not made of copper, as in Eco Four, but of plastic.
Due to this, the manufacturer managed to reduce the price of wall-mounted double-circuit gas boilers with two heat exchangers, and some buyers appreciated this: after all, boilers of this series also found their firm place in the market. This was especially noticeable during the collapse of the ruble against the dollar and the euro.
Specifications Baxi Four Tech
Additional functions and boiler control
All models are equipped with a digital control panel, on which you can set the boiler operation mode, the temperature of the water in the heating system and hot water, set the mode of underfloor heating in the temperature range of 35-45 degrees. It is also possible to regulate the operation of the boiler depending on the weather outside the window, thanks to weather-dependent automation, by connecting a special outdoor temperature sensor.
Or buy Baxi and set the temperature in the room.
But, unfortunately, these accessories are not included in the package and must be purchased separately.
The only exception is the Luna-3 Comfort model with a remote control panel.
In addition, the display shows errors when the Baxi boiler is operating under certain codes, for example, “E 06” - the DHW temperature sensor is faulty, etc.
Advantages of Baxi wall-mounted gas boilers
- a wide range of models;
- many service centers in Russia and the CIS countries;
— Availability of spare parts from official representatives (dealers);
- reasonable cost.
Disadvantages of Baxi boilers
- weak electronics (in particular, an electronic board);
- high sensitivity to running water of poor quality;
— not "native" spare parts.
