If previously reliability was valued above all else in heating equipment, today they are also expected to be able to operate in automatic mode.
The English holding Baxi Group, a well-known manufacturer of gas boilers, takes these requirements into account: the units it produces, due to their high quality, are in good demand in our country.
Our article will help you evaluate their merits, the topic of which is the Baxi gas boiler: instructions for use.
In terms of their design, TM Baksi units are not much different from other gas boilers. They consist of several components.
This node includes several elements:
The combustion chamber of TM Baksi boilers is closed, that is, air is taken into it from the street. The only exception is the Luna-3 Comfort 240i model, which has an open camera.
The pipe for connecting the gas supply line is located in the middle between the pipes for connecting the heating system.
The latter are more efficient due to their high thermal conductivity.
The successful design of the heat exchanger allows you to absorb 90.8% of the heat generated in the combustion chamber (some models have a slightly lower efficiency - 88.7%).
In addition to the main heat exchanger, the Baksi heater may contain another one intended for cooking hot water. Such boilers are called double-circuit boilers. Some models, for example, Baxi Ecofor 24, can heat water in an external boiler.
A mesh filter is installed at the inlet of the heat exchanger.
For different models, the volume of this element can be 8 or 10 liters.
Russian manufacturers heating equipment have made a lot of progress in the quality of their equipment. Among the popular companies is Conord. users and characteristics overview, read carefully.
The heating diagram for a house with a gas boiler is presented.
Autonomous home heating is an attractive option for any owner.
If one device also provides hot water supply, then this option is optimal under any conditions.
There are a lot of installations that perform such functions and have high performance qualities.
A striking example of such heating devices is the Baxi Main 24 Fi double-circuit gas boiler, which has extensive capabilities and has been specialized for Russian technological and climatic conditions.
The unit is highly rated by users and deserves detailed consideration.
The well-known Italian company Baxi, part of the BDR Thermea Group, has been working on the manufacture of heating equipment for more than half a century.
During this time, many technological methods have been developed that allow us to produce high-class products that meet all the requirements and standards accepted in Europe. Baxi Main 24 Fi is one of the models of double-circuit wall-mounted boilers using natural or liquefied gas as fuel.
Almost 70% of the company’s products are intended for export, so manufacturers take into account the conditions upcoming work. The units undergo special training to comply with Russian conditions.
They tolerate changes in gas pressure and are able to compensate for a slight decrease in voltage in the electrical network.
Among Russian users, Baxi products are deservedly in high demand and preference.
Baxi Main 24 Fi is a double-circuit boiler capable of simultaneously supplying hot water and heating the coolant for heating systems or underfloor heating. The numbers 24 indicate the boiler power (24 kW), and the letters Fi indicate the turbocharged combustion chamber.
It has a closed design that ensures tightness and cleanliness of the surrounding air.. The combustion mode is maintained by a fan supplying air flow to the burner.
The main feature of the Baxi Main 24 Fi boilers is the bithermal heat exchanger. Unlike other series, not two separate, but one combined version was used.
It is a design in which another tube is installed inside the tube, having a shape close to a rhombus.
By outside the coolant flows, and the inner, rhombic shape is hot water. The OM flow receives thermal energy from the burner, and the DHW flow from the coolant. This design makes the boiler design simpler, more compact, and simplifies adjustment and configuration.
Set of functions of the Baxi Main 24 Fi boiler:
NOTE!
The functionality of Baxi boilers is almost the same for all models. There are only small features that do not represent a fundamental difference.
For convenience and ease of consideration, we will provide the parameters of the Baxi Main 24 Fi boiler in the form of a table:
The advantages of Baxi Main 24 Fi boilers are:
The disadvantages include:
Both the advantages and disadvantages of the Baxi Main 24 Fi boiler are due to design features. Most of them are general qualities gas boilers.
The main elements of the boiler design are:
The operation of the boiler is to heat the coolant using a heat exchanger and a gas burner. The outgoing OM is mixed with the colder return flow, obtaining the specified temperature parameters.
At the same time, hot water is heated in the heat exchanger, passing through the inner tube and receiving energy from the hot heating agent. The combustion mode and the removal of fuel combustion products are provided by a fan receiving fresh air from the external pipe of the coaxial chimney.
All processes are monitored by a system of sensors, which, when problems occur, signal to the control board and display one or another error code on the display.
Almost all processes occur automatically, user intervention is minimal and is aimed only at adjusting the operating mode.
Baxi Main 24 Fi boilers are designed and designed for use in residential premises - houses or apartments of the appropriate size. They are often installed in office or public spaces.
Such units are not recommended for use in industrial workshops, since the specifics of the work will be too harsh and will cause rapid failure of the unit.
The declared area of the heating circuit is 240 m2, although in practice it is not recommended to use this model for rooms larger than 200-220 m2 due to the gradual decrease in the boiler's capabilities resulting from contamination, the appearance of scale and general wear and tear of the unit components.
After delivery, installation of the boiler in the designated place and connection of all communications, it is necessary to carry out the initial start-up of the boiler.
Procedure:
NOTE!
The process may not start the first time due to the presence of air in the system. In such cases, the procedure is repeated until the boiler starts up normally.
The boiler operates automatically, requiring virtually no user intervention. The owner is required to periodically perform maintenance using the services of an invited specialist from the service center.
To improve operating conditions and extend service life, it is recommended to install a voltage stabilizer and a water softening filter. It is especially important to improve water quality if the power comes from your own well and standard water treatment has not been carried out.
Before starting operation, you should carefully study the user manual in order to understand important points and avoid unacceptable actions.
All malfunctions that are possible during the operation of the boiler are immediately detected by the corresponding sensors and displayed on the display in the form of a corresponding code.
The user's first reaction when an error occurs (if there is no visual confirmation of the problem) should be to reset the error by pressing the R button and holding it for 3 seconds. If the error occurs again, you need to call a technician.
Let's consider the opinions of people who operate Baxi Main 24 Fi boilers in their homes.

Wall mounted Baxi gas boilers literally filled Russian market heating equipment over the last decade. This is not surprising. When a potential buyer is faced with a choice: to buy an inexpensive boiler, but unfinished and domestic, or a reliable, but expensive one made in Germany, the choice is often made in favor of Italian manufacturers of gas boilers.
As a rule, they are distinguished by a fairly good price-quality ratio and a developed network Maintenance, easy to find spare parts. Let's consider the most popular brand of gas boilers in Russia, Baxi, reviews of which we can often read on specialized forums, online blogs or on the company's official website.
We will analyze in detail the main models, types, design, technical characteristics of wall-mounted (mounted) single-circuit and double-circuit gas boilers Baksi, identify their main advantages and disadvantages, and also understand how they differ from each other according to the operating instructions.
Basic models of wall-mounted gas boilers from Baxi
The following models of wall-mounted gas boilers from Baxi are available on our market:
— Baxi Main Four and Baxi Main 5 (fourth and fifth generation of boilers);
— Baxi Four Tech and Baxi Eco 4S;
— Baxi Eco Four and its more compact analogue Baxi Eco Compact;
— Baxi Luna-3 and Luna-3 Comfort with a remote control panel;
— Baxi Nuvola-3 with built-in storage boiler.
Baksi wall-mounted gas boilers differ in the type of exhaust of combustion products and are:
1. Baxi turbocharged gas boilers with a closed combustion chamber
A special fan (turbine) is installed in the boiler, with the help of which combustion products are forcibly removed from the boiler into the atmosphere. To do this you will have to buy additional coaxial chimney, or a pipe system for separate smoke removal and air supply.
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 to the street. This is very convenient, because... there is no need to specially fence the chimney through the roof.
Such models are designated by Baxi with the article number “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 to us the power of the boiler, i.e. 18 or 24 kW.
2. Atmospheric boilers Baxi with an open combustion chamber
If your private home already has a chimney with a diameter of at least 130 mm, then you can buy a boiler with an open chamber, the combustion products of which are released due to natural draft. Such boilers are often called “aspirated” boilers.
On the Baxi boilers themselves, the diameter of the smoke outlet pipe is 121-122 mm, so an aluminum corrugation with a diameter of 125 mm, capable of withstanding temperatures up to 400 degrees Celsius, which can be stretched up to three meters, is suitable for them. Or you can use chimney pipes from of stainless steel the same diameter. True, this chimney option will cost a little more.
These models do not have a turbine, and the Baxi boiler is marked with the article “i”, or it is not indicated 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 boiler only provides 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 that of 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 cannot be connected at all.
You can simply buy a Baxi double-circuit gas boiler, even if there is no running water in the future. After all, perhaps after some time you will find the second circuit of this boiler useful, and you will not have to buy a new device.
2. Dual-circuit.
Such boilers are most popular among buyers, as evidenced by numerous reviews of Baxi gas boilers. They are able to work both as a heating unit and as a flow-through gas water heater. Moreover, when 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 in greatest demand among potential buyers. By purchasing such a boiler, we get both a heating boiler and geyser for hot water supply.
Design features of Baxi double-circuit gas boilers: instructions
1. All models are equipped with two separate heat exchangers (except for boilers of the Main Four and Main 5 series) for heating water in the heating system and utility water 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 made by German manufacturers, either Grundfos or Wilo. This pump is capable of lifting a column of water heating system up to 6 meters, which is quite enough for two-story house or cottage. The circulation pumps built into the boilers are quite economical and are equipped with an automatic air vent.
3. To maintain the required pressure in the heating system, Baksi boilers have a built-in membrane expansion tank volume 6-10 liters. There is no need to purchase an additional one if the total volume of water in the system does not exceed 100-150 liters. You can find out this individual volume yourself 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, gas-burner has flame breakers made of stainless steel. All models automatically maintain the water temperature in the heating system and in the DHW circuit thanks to smooth electronic modulation of the burner.
The boiler safety group includes:
— automatic air vent;
— safety valve with pressure gauge.
Let's consider the device of a double-circuit gas boiler using the example of the “Baxi Eco Four 24F” model according to the diagram:
1 - hydraulic pressure switch
2 - three-way valve
3 - three-way valve motor
4,22 — safety valves at 3 Bar
5 - Honeywell gas valve
6 - gas supply tube to the burner
7 - water temperature sensor in the system
8 - flame spark plug
9 - overheat protection sensor (thermostat)
10 - main heat exchanger
11 - smoke hood
12 - turbine for exhausting combustion products
13 - Venturi tube
14,15 — position points. and negative pressure
16 — traction control sensor
17 - gas burner
18 - expansion membrane tank
19 - circulation pump
20,21 — drain valve and pressure gauge
23 - tap for recharging the heating system
24.25 - temperature sensors of the DHW circuit
In addition, wall-mounted boilers have a built-in electronic board, the so-called. the “brains” of the boiler, various sensors: flow, temperature of the DHW and heating circuits, as well as draft and flame sensors. There is a boiler protection system against freezing and blocking circulation pump. This does not cancel the mandatory purchase of a voltage stabilizer for a boiler of this brand.
Baksi gas boilers: differences between models and technical characteristics
As we see, the lineup boilers at this Italian manufacturer wide enough. 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 the boiler models of the Baxi Main Four and Baxi Main 5 series
The predecessor of this series of boilers were devices called Baxi Main, which did not have an LCD display and a number of other functions. In general, the word “Main” translated from English means “main” or “main”. Also in our case, the “Main” series boilers are the basic version of the wall-mounted gas boiler from the Baxi company.
Their main distinguishing feature is the presence of a bithermal heat exchanger. This means that both the heating system circuit and the DHW circuit are heated in one heat exchanger. The water in the circuits does not mix, and the running water is heated precisely by the heating circuit.
Fifth generation boiler Baxi Main 5 It attracts with its compact size, but is only available 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, and have a model range with a power of 14, 18 and 24 kW.
Features of the Baxi Eco Four and Baxi Eco Compact boiler models
The main feature of these models is the presence of an additional plate secondary heat exchanger made of stainless steel for heating the DHW circuit.
The main (primary) heats water only in the heating circuit, and the secondary works independently of it, using 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 increases.
Model Baxi Eco Compact already in its name indicates to us its small dimensions, due to its better layout internal elements, compared to 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 the wall-mounted gas boilers of the third series, Baxi Eco 3 Compact.
Features of Baxi Four Tech gas boiler models
Boilers series Baxi Four Tech- This is a cheaper version of the Eco Four series boilers. They are also equipped with two separate heat exchangers made of copper and stainless steel. Their distinctive feature is that the hydraulic part (water supply tubes) 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 period of the collapse of the ruble in relation to the dollar and euro.
Additional functions and boiler operation control
All models are equipped with a digital control panel, on which you can set the boiler operating mode, the water temperature in the heating system and hot water supply, and adjust the underfloor heating mode in the temperature range of 35-45 degrees. It is also possible to regulate the operation of the boiler depending on the weather outside, thanks to weather-dependent automation, by connecting a special outdoor temperature sensor.
Or buy a room thermostat for the Baxi boiler and set the room temperature.
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” - faulty temperature sensor DHW, etc.
Advantages of Baxi wall-mounted gas boilers
— wide model range;
— many service centers in Russia and the CIS countries;
— availability of spare parts official representatives(dealers);
- reasonable cost.
Disadvantages of Baxi boilers
- weak electronics (in particular, electronic board);
- high sensitivity to running water Bad quality;
- not “original” spare parts.
Results
Today we examined in detail the wall Baxi gas boilers, reviewed the advantages and disadvantages of the models, their technical characteristics, according to the operating instructions. We also compared how the main models of this brand of boilers differ and made our own review of them.
I will not recommend or dissuade you from purchasing, the choice is yours. Read reviews and analyze Baxi gas boilers. Let me just say that the price-quality ratio for Baksi boilers is quite good, even despite the fierce competition in the heating equipment market. Let's watch the video review.

Autonomous heating does not depend on heating networks. And this is perhaps the main advantage. You can regulate the temperature in the room yourself, and if necessary, turn off the heating altogether. On average, over 5 years, equipment for autonomous heating completely pays off.
The comfort, efficiency and reliability of home heating depend on the choice of boiler. If your home is located in a gasified area, then it makes sense to purchase a gas boiler.
Running water is designed to provide hot water in the house. gas heater. It was previously installed in apartment building. Now the models have been improved and are equipped with a gas control and ignition system.
A single-circuit gas boiler is used to heat homes small area. It is simple, powerful, but its operation has its own characteristics:
A boiler with an open combustion chamber requires increased caution and strict compliance with fire safety and sanitary requirements. Among single-circuit boilers there are boilers with a closed combustion chamber, but they are more expensive.
A double-circuit gas boiler can not only heat a room, but also heat water. One circuit works for water heating, and the second for heating.
The design and construction of Italian gas boilers meet the needs of modern heating. The Baxi Luna gas boiler can be placed on any free space walls. It does not require a special room for placement - everything it needs to work is already provided for by the internal structure.
All Baksi wall-mounted gas boilers undergo mandatory certification for compliance with operating safety requirements. Consumer reviews most often confirm the ease of operation of the boiler and its safety.
The units are equipped with a special control system, which is capable of diagnosing the operation of the system and taking into account weather conditions. If there is a drop in gas pressure at the main inlet, this will not affect the operation of the gas boiler in any way.
Single-circuit gas heating boilers are designed to heat the house. They decided to make the wall-mounted “Baksi” more functional and installed special outlets for installation additional boiler. It is possible to heat water for household needs.
Single-circuit boilers are designed quite simply. The burner that ignites the gas is placed inside a safe thermal envelope. The heat that accumulates in the combustion chamber is transferred to the heating circuit through a heat exchanger.
The material for the manufacture of the heat exchanger is copper, cast iron or steel. This type of boiler is designed for low power - from 14 to 31 kW. Wall-mounted Baxi are small in size and are made with a closed or open type chamber.
The boiler design provides for a heat exchanger that is connected to the heating system. Water heating occurs once in a closed cycle. Then the heat exchanger only needs to maintain the required temperature.
The heat exchanger, which is connected to the water heating system, is secondary, and a new portion periodically enters it cold water, so it is forced to work constantly to heat up.
Types of heat exchangers on Baksi boilers:
Perhaps the most popular and advanced is the Baksi double-circuit gas wall-mounted boiler. Reviews, in any case, are exactly like that. The model is considered successful and reliable. There are several reasons for this:
The use of such boilers provides significant savings on blue fuel. The system has a built-in turbocharger, and this allows you to obtain the required amount of heat with lower gas consumption. A fan is additionally installed in the boiler, which blows air from the street.
Cold air enters through a pipe built into another, larger diameter, which works to remove combustion products. The design is completely sealed and prevents harmful toxins and fumes from entering the room.
The principle of their operation is based on the laws of physics. Typically, gas burns in the boiler chamber and combustion products are discharged outside. In condensation, the procedure is slightly different.
When carbon burns, it produces carbon dioxide and water vapor. The installed heat exchanger cools the steam and uses the released energy to heat the circuits. Its efficiency significantly exceeds that of simple gas boilers.
A wide range and optimal consumer properties are distinguished by Baksi gas boilers. Reviews from owners who have installed floor option boilers, indicate their uninterrupted operation. And this is thanks to the excellent quality of their execution.
Gas floor-standing boilers "Baksi" have a built-in electronic self-diagnostic system that monitors operating parameters and, if necessary, adjusts them in the event of a drop in pressure in the line.
The Baksi gas boiler operates completely autonomously, without any intervention. Errors in the operation of the boiler or a decrease in pressure in the pipeline lead to prompt shutdown of the gas supply to the burner.
Floor-standing boilers are produced in several versions. You can choose it to suit the needs of your home, cottage or production premises, where it is necessary to maintain a constant temperature, the most suitable gas floor-standing boiler is “Baksi”. Owner reviews indicate that connection errors are virtually eliminated and the models are extremely simple. Unit installation specialists will customize them to the homeowner's needs.
Range of floor-standing gas boilers "Baksi":
The operating principle is the same as for wall-mounted boilers. On the heat exchanger, the process of reverse conversion of the dispersed part into liquid takes place. During the transition, additional energy is released, which significantly increases the energy intensity of the boiler.
The Baksi gas boiler has a separate source for igniting the burner. The units are used in various conditions. To increase the safety of using the unit, we manufactured an atmospheric gas boiler “Baksi”. The instructions instruct to install it in a place where it is possible to connect a chimney, gas pipe, heating and water supply systems.
IN atmospheric boilers thermocouple controls uninterrupted operation products. The boiler's dependence on energy resources is eliminated, and if the burner flame goes out, the inlet valve closes. This device managed to increase the safety of operation of a gas boiler.
Gas floor-standing boilers “Baksi”, which have two independent circuits, will heat the house and prepare hot water. The thermal energy that is generated is spent on maintaining the already obtained heat transfer regime. The periodic supply of cold portions of water forces the boiler to constantly work to heat up.
The Baxi Slim gas boiler is compact and independent of electricity. It is made of cast iron, has an atmospheric burner and automation, which will ensure the safe use of the unit by closing the gas valve. In the model line, the Baxi Slim gas boiler is represented by 5 varieties. They differ in power.
There may be problems that disable the Baksi gas boiler. The installation instructions must always be followed.
Problems with the boiler may arise if an incorrectly selected chimney is installed. Specialists in the field insist on installing a coaxial chimney, which is also produced by Baksi.
However, if you already have a proven, reliable chimney and you have no doubt about its serviceability, then it is possible to connect to it. This will save the owner some money.
It is easy to maintain Baxi Slim gas boilers. User reviews indicate that if you need to clean any compartment of the unit, you can do it yourself, without resorting to the services of professionals.
You can easily set up the Baksi gas boiler yourself. The control instructions are simple, and the LCD information display will give a comprehensive picture of the settings. The consumer can set the power himself; he must set the desired program and set the required minimum and maximum values.
The Baksi gas boiler has a built-in self-diagnosis system. He himself can not only identify the breakdown, but also eliminate it. short time. The display shows all the information to adjust and set the system pressure and water temperature.
Any equipment is subject to breakdowns, but everything is compared in percentage terms. Judging by the reviews of the owners, Baksi gas boilers are of high quality, easy to control, fully automated and do not require complex maintenance.
If complaints arise, the breakdowns are insignificant and they do not always occur due to poor quality of the boiler itself. It is necessary to monitor the draft in the chimney so that the water pressure sensors do not fail. There may be scale on the heat exchanger, but this can also be quickly corrected.
Italian gas boilers "Baksi" regularly receive positive reviews from users. They have proven themselves in the market to be safe, productive and environmentally friendly, and have modern design and high-tech automation, fully meet customer expectations and will not disappoint discerning users.

In terms of their design, TM Baksi units are not much different from other gas boilers. They consist of several components.
This node includes several elements:
The combustion chamber of TM Baksi boilers is closed, that is, air is taken into it from the street. The only exception is the Luna-3 Comfort 240i model, which has an open camera.
The company installs both steel and copper heat exchangers in its units.
The latter are more efficient due to their high thermal conductivity.
The successful design of the heat exchanger allows you to absorb 90.8% of the heat generated in the combustion chamber (some models have a slightly lower efficiency - 88.7%).
In addition to the main heat exchanger, the Baksi heater may have another one designed for preparing hot water. Such boilers are called double-circuit boilers. Some models, for example, Baxi Ecofor 24, can heat water in an external boiler.
A mesh filter is installed at the inlet of the heat exchanger.
For different models, the volume of this element can be 8 or 10 liters.
All units of this brand use volatile automation. The total power consumption of the boiler, depending on the model, is 135 or 165 W. For most models, for example, Luna-3, Eco-3, Slim, Nuvola, the automation is weather-sensitive.
This means that in addition to the timer and room thermostat, you can connect an outdoor temperature sensor to it. Taking into account weather conditions allows the system to timely switch the boiler to the optimal mode, which makes the heating system more economical.
The wall-mounted model Luna-3 Comfort (3rd generation boiler) uses a temperature sensor instead of a room thermostat.
TM Baxi boilers can operate in two modes:
The first involves heating the coolant to 85 degrees with a return temperature of about 30 degrees. The second is designed for a temperature ratio of 45/30 degrees (supply/return) and is intended for “warm floor” systems. This mode can also be used with conventional radiator heating during the off-season.
So, let's look at the Baksi gas boiler - operating instructions, setup and adjustment. To set up the boiler, just set the desired temperature on the room thermostat - the unit will do the rest itself. All data is shown on the display. The most convenient are thermostats with a programming function, through which you can plan the boiler operating schedule for a day or a week in advance (depending on the model).
In Luna-3 Comfort series boilers, the controller is removable and can control the operation of the boiler remotely. It looks like a panel with a display and keys, which also contains a room temperature sensor.
The controller is located in one of the rooms on any convenient location and with its help they adjust the operation of the heater. On it you can view the results of self-diagnosis and, if necessary, view a list of recent errors - it is stored in memory.
To prevent breakdowns of the Baksi boiler and thereby extend its service life, this unit should be connected to the electrical network through a stabilizer. Imported electronics are designed for power supply High Quality and if its parameters deviate significantly from the norm, which we still see quite often, it easily fails.
At certain intervals (after several years of operation), the outside of the heat exchanger must be cleaned of soot. If it is made of stainless steel, you can use a special brush with metal bristles. This tool is not suitable for cleaning a copper heat exchanger, as it can damage it. It is better to use a metal sponge designed for washing dishes.
The heat exchanger of the DHW circuit needs to be washed from time to time with some descaling agent. The same must be done with the main heat exchanger if ordinary water that has not undergone the desalting procedure is used as a coolant.
The fan must be periodically lubricated, otherwise over time the engine will not be able to rotate it at a sufficient speed. Unscrew the back of the assembly and remove the stator, after which you will need to pour a few drops of machine oil inside.
TM Baxi boilers have a self-diagnosis function, thanks to which these units independently detect their own faults. The test results are displayed on the display in the form of an alphanumeric code. Each code indicates several possible faults. Below are the most common ones.
The cause of overheating may be a clogged heat exchanger with scale, a breakdown of the circulation pump, a clogged filter, or the appearance of air lock in the heating circuit.
False alarms of the system are possible due to a breakdown of the temperature sensor or its insufficient contact with the coolant (should be installed with thermal paste).
The chimney is clogged with soot or condensation, is too long or has an incorrect design (for example, there is no mandatory vertical section at the beginning, with a length of at least 2 diameters). Be sure to check the fan for functionality.
Triggers when the burner goes out repeatedly (more than 6 times). It is necessary to check whether flue gases are leaking into the duct. The reason may also be voltage fluctuations.
The error appears when this sensor fails or when its contact with the board is broken.
If this sensor signals a gradual or sudden decrease in temperature in the DHW circuit, the 3-way valve may have failed.
It is checked as follows:
This message is displayed mainly due to a breakdown of the circulation pump or a clogged heating circuit. The filter and heat exchanger are more susceptible to this (they become overgrown with scale).

All Baksi gas boilers have a number of features that significantly improve the user characteristics of the device. The advantages of the equipment can be described in the form of a short list.
Another advantage, which is somewhat implicit to the buyer, is the orientation of Baksi units for complex use. For example, the instructions for using the Baxi gas boiler make it clear that if connected using boilers from the same company, better results will be obtained.
Also, the “gas boiler with Baksi boiler” lines provide direct connection electronic control circuits to create a flexible control system. If we talk about the disadvantages of boilers of this brand, the following points can be noted.
The high price in the eyes of potential buyers is a key factor that the Baksi name has not yet become widely known in the markets of the post-Soviet space.
In the offered lines you can find almost any model. The design of a Baxi gas boiler involves the use of all three main engineering solutions:
Among the equipment suitable for heating an apartment or small house, there are a huge number of wall-mounted gas boilers. Both single-circuit and double-circuit models are presented. Within the framework of boilers that provide for floor placement, there are a lot of models that require joint piping with the boiler. You can implement any of the basic schemes:
Some characteristics of equipment suitable for heating an apartment.
Most interesting for residents apartment buildings, as well as owners of small cottages and private houses wall-mounted boilers series Main, ECO Compact, Fourtech. These boilers are compact in size, do not have any special installation requirements, allow connection to any piping options, and their performance is sufficient to meet the needs of most users.
To illustrate this, we need to compare devices running on different principles. For a small room, based on size and thermal power, Fourtech series boilers are ideal.
| Model | BAXI Fourtech 24 | BAXI Fourtech 24 F |
| Combustion chamber type | Open, atmospheric | Closed, supercharger |
| Net heat output, kW | 24 | 24 |
| Minimum performance, kW | 9,3 | 9,3 |
| Efficiency at maximum performance | 91,20 | 92,93 |
| Efficiency at 30% power level | 89,3 | 90,37 |
| Gas consumption, cubic m/h | 2,78 | 2,73 |
| Overall dimensions in mm | 730x400x299 | 730x400x299 |
| Weight, kg | 29 | 33 |
As can be seen from technical characteristics, with very compact dimensions of the device and low weight, good thermal energy output is ensured. For comparison, the closest competitors from VAILLANT, equal in power, have larger dimensions and a third higher weight. The advantage of a unit with a closed combustion chamber is also immediately noticeable. It has lower gas consumption at all power levels, as well as better efficiency. When the piping works with a boiler, the financial investment will pay off much faster.
If we talk about problems, it is worth immediately noting that electronic control systems ensure maximum safety. Technical solutions embedded in a special operating algorithm allow us to raise the level of reliability even higher. 
However, some glitches do occur. Individual malfunctions and methods for solving them are given in the instructions for using the Baxi gas boiler. Typical problems can be identified by the fault code on the indicator.

Baksi gas boilers are reliable equipment, the level of user characteristics of which fully corresponds to the high price. Thoughtful operating modes guarantee long service life, and the use of boiler trims and joint control can provide excellent economic efficiency of the heating system as a whole. Baksi boilers, thanks to the ability to be equipped with sensors and thermostats, can operate without human intervention, providing excellent temperature regime premises.
Among the many offers climate control technology a new name has recently appeared for the house. If you look through the instructions for the Baxi gas boiler, a well-known manufacturer from Italy, it seems that the equipment is no different from its competitors. However, the product line includes products that differ both in the operating algorithms used and in the ability to implement complex solutions for heating a home.
All Baksi gas boilers have a number of features that significantly improve the user characteristics of the device. The advantages of the equipment can be described in the form of a short list.
Another advantage, which is somewhat implicit to the buyer, is the orientation of Baksi units for complex use. For example, the instructions for using the Baxi gas boiler make it clear that if connected using boilers from the same company, better results will be obtained.
Also, the “gas boiler with Baksi boiler” lines provide for direct connection of electronic control circuits to create a flexible control system. If we talk about the disadvantages of boilers of this brand, the following points can be noted.
The high price in the eyes of potential buyers is a key factor that the Baksi name has not yet become widely known in the markets of the post-Soviet space.
In the offered lines you can find almost any model. The design of a Baxi gas boiler involves the use of all three main engineering solutions:
Among the equipment suitable for heating an apartment or small house, there is a huge number of wall-mounted gas boilers. Both single-circuit and double-circuit models are presented. Within the framework of boilers that provide for floor placement, there are a lot of models that require joint piping with the boiler. You can implement any of the basic schemes:
Some characteristics of equipment suitable for heating an apartment.
The most interesting for residents of apartment buildings, as well as owners of small cottages and private houses, are wall-mounted boilers of the Main, ECO Compact, and Fourtech series. These boilers are compact in size, do not have any special installation requirements, allow connection to any piping options, and their performance is sufficient to meet the needs of most users.
To illustrate this, we need to compare devices operating on different principles. For a small room, based on size and thermal power, Fourtech series boilers are ideal.

If you think that you can install and connect a gas boiler yourself, you are mistaken. Even if you carefully study the instructions for the Baxi double-circuit wall-mounted gas boiler and acquire the necessary tools, no one will give you permission to carry out such work. It is important to know that the installation, and especially the connection of gas equipment, should only be carried out experienced craftsmen who are able to carry out everything in compliance with the requirements and rules.
Upon completion of all work, the technician will certainly perform the first startup of the Baxi gas boiler, which will allow him to check the quality of the work performed. If everything is in order, the equipment is put into operation. Despite the fact that the installation and connection of gas boilers is carried out by a specialist, you should know how to properly install wall-mounted and floor-standing heating boilers, and also carefully study the structure of the Baxi gas boiler - this will allow you to properly operate the equipment in the future.
First of all, we open the packaging of the device and check the contents; if something is missing, we go to the store and buy more.
We check the surface on which the boiler will be installed. If it is made of flammable materials, it is necessary to attach a heat-resistant coating to the surface, and in this case the device is mounted from the surface at a distance of up to 5 cm.
Please note that installing a Baksi gas boiler yourself can be done at this stage, since preparatory work may not be the responsibility of specialists. Their task is exclusively connection and installation.
Before installing the device, it is recommended to wash the internal tubes, into which small debris and dust may have entered during transportation and storage in the warehouse. Only after completing these works can you begin the installation process, which includes eight steps.
Before starting all work, check the number indicated in the passport with the number on gas appliance which will be installed. This point should be checked before purchasing. If the numbers do not match, the boiler may not be registered.
If necessary, in order to increase the efficiency and economy of the device, the technician may recommend installing a room thermostat for the Baxi gas boiler, which will allow you to regulate the heating temperature of the coolant based on room temperature parameters
We check the contents and compliance of the numbers in the passport and on the equipment. After this, attention turns to the room in which it is planned to install the equipment.
If you do not want to frequently repair Baksi gas boilers, it is recommended that you trust the installation and connection to specialists.
The surface on which installation will be performed must be perfectly flat. It is recommended to place a sheet of metal on the floor surface, which should protrude beyond the structure of the device by at least 10 centimeters, and from the front side by 30 cm.
Provided that the installation of the Baksi gas boiler was carried out by a qualified specialist, we can speak with confidence about the quality of all connections and that the device will serve for a long time and properly for many years. Of course, the latter will depend only on how correctly the gas heating boiler is operated. Please note that the equipment may become out of working order and require repairs either through the fault of the user or through no fault of the user.
There are other malfunctions that may occur during operation. In order to protect yourself as much as possible from unexpected breakdown of the device during the heating season, it is recommended to carry out maintenance of the unit at least twice a year.
Experts advise that any gas equipment, for example, a wall-mounted double-circuit turbocharged gas boiler Baxi, be checked for quality of operation before and after the heating season. With such a responsible approach, the equipment is guaranteed to serve properly and, most importantly, reliably.
Many people install generators to protect themselves and their expensive equipment. Of course, this is a good solution. But there is a much simpler and less expensive solution to the issue.
All that is required is to install a five percent Stihl thyristor stabilizer with a power of 1.2 kW and SmartUps 1000. Next, we replace the 24-volt internal battery installed in the uninterruptible power supply with two 12V car batteries, each of which has a capacity of 75 A/ h. We connect the batteries to each other in series. As a result, we get an additional energy reserve of 150A/h.
Note that when the fan, circulation pump and boiler are operating at full power, the battery charge will be enough for approximately 11–12 hours of operation, which is quite enough to emergency situation was decided.
