Consider the basic structure of the Baxi boiler. The schematic diagram is printed in the operating instructions for each specific model, but the main components will be the same.
The chimney is located at the top. A fan with a Venturi tube and an exhaust hood for the removal of combustion products are installed immediately below it. Below is the primary heat exchanger, which looks like a radiator and a coil, a little to the left is a safety thermostat and an NTC heating temperature sensor.
In the center is the combustion chamber, inside which there is a burner and electrodes for ignition and flame ionization. Connected to the modulating burner gas train with nozzles, which is supplied with gas from the gas valve.
WITH right side a pipe comes out of the heat exchanger and is connected to an expansion tank and a circulation pump. The pump is equipped with an automatic air bleed valve. It ends at the bottom with a tap for draining the coolant from the apparatus and a pressure gauge, water from the heating system of the house enters it.
On the left side, a pipe is lowered, on which a hydraulic pressure switch and a safety valve at the end are installed. Water comes out of it into the heating system. These pipes are connected to each other by an automatic bypass.
In dual-circuit models, a secondary plate heat exchanger, a DHW priority sensor and a three-stage valve are additionally installed. The Baksi Luna 3 Combi and Nulova 3 series are equipped with an indirect boiler of small volume.
Main 5 boilers are equipped with a bithermal heat exchanger, which simultaneously heats both running water and a heat carrier. This is realized due to the fact that inside the pipe through which the liquid from the heating system flows, there is another pipe of a smaller diameter through which tap water flows. 
An electronic control board is installed in front. The wiring diagram printed in the operating manual shows where all the elements and sensors of the boiler are connected to. From it you can figure out how the electrical part of the equipment works.
A steel casing is installed outside, on which an electrical control panel with buttons for switching on and selecting an operating mode is located below. V modern models a display is installed to output technical data and error codes in the event of a malfunction.
Let's figure out what is the principle of work gas boiler Baksi. The coolant enters the system of the device through the right pipe, driven by a circulation pump. Then it enters the heat exchanger.
When the temperature of the liquid falls below the set in the control panel settings, gas valve supplies fuel to the burner and the ignition electrode is triggered. A flame ignites and heats up the heat exchanger. When heated, the coolant expands and its excess enters expansion tank.
The coolant comes out through the left pipe, passing through the temperature sensor. When the water has heated up to the set level, the gas flow to the burner is shut off. An external room thermostat can also regulate the operation of the boiler, in this case the operating cycles will be tied to the room temperature.
In the two-circuit series, the three-stage valve changes the priority of DHW and heating, depending on the needs of the consumer.
The piping of such a boiler is quite simple, since all functional elements are configured and located inside the body. You need to calculate the required number of radiators, draw a diagram, and then connect them together and bring all the pipes to the device.
So that by the name you can determine the type of boiler, let's figure it out with the marking. The symbol "F" or "Fi" indicates that the boiler is turbocharged with a closed combustion chamber. Atmospheric vehicles have the letter "i". The word “Comfort” means that the set comes with a remote control panel, the mark “Air” says that this panel is remote.
The first number after the name of the series reflects the generation of the boilers, and the second the power. For example, the fourth generation Baxi Eco Four 24 F with closed chamber combustion and a power of 24 kW.
Boiler Baxi Eco Four 24 F
The fifth generation Main 5 series is the next step in the development of boilers Baxi main Four 240 F. Includes three wall-mounted models with 14, 18 and 24 kW. All of them are double-circuit due to the installed bithermal heat exchanger, they have electronic protection against scale. Equipped with a closed combustion chamber. The configuration is very adaptive, the boiler operates at a reduced gas pressure of up to 4 bar and power voltage drops from 170 to 270 V.
Boiler panel Baxi Main Four 240
The development of the outdated Eco 3 Compact series was the ECO Four (Ecofor), Eco 4s and Eco 5 Compact lines. Baxi Eco Compact devices are small in size due to the optimized internal arrangement of the main components. They include single-circuit and double-circuit devices with a secondary plate heat exchanger made of stainless steel.
Baxi Eco Compact 4s boiler
V hydraulic system includes an economical circulating pump with automatic air venting. The range includes 18 models with closed and open combustion chambers from 14 to 25 kW. They have a liquid crystal display. Eco 5 Compact devices can be connected to an integrated solar circuit.
The Baxi Four Tech line (Fortech) is a cheaper analogue of the Eco Four series due to the plastic water supply pipes. The Luna 3 and Luna 3 Comfort editions offer single and double circuit units from 24 to 31 kW. Can work for liquefied gas... The burners have continuous electronic flame modulation.
Baxi Four Tech boiler
The electronic board has a self-diagnosis function and the possibility of weekly programming. The Comfort series is completed with a remote control panel with a built-in room temperature sensor. In Luna 3 Combi devices, DHW is provided by a built-in eighty-liter boiler indirect heating made of stainless steel Combi 80.
Floor-standing boilers Baksi Slim have very compact dimensions, a stylish gray body with a black control panel and are equipped cast iron heat exchanger... The Slim 2 models are equipped with an indirect heating boiler with a capacity of 50 or 60 liters.
The circulation pump operates at three speeds. Power range from 15 to 62 kW. It is possible to connect a programmable timer. Slim EF devices are equipped with a gas automation with a thermocouple, which allows operating in a non-volatile mode with natural circulation of the coolant.
In conclusion, we offer a video about the device of the BAXI eco four 24 f boiler:
Among the many proposals of climate technology for the home, a new name has appeared relatively recently. If you flip through the instructions for the Baksi gas boiler, a well-known manufacturer from Italy, it seems that the equipment is no different from competitors. However, the product line includes products that differ in both the applied work algorithms and the ability to implement complex solutions for heating a house.
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 summarized in a short list.
Another advantage, which is somewhat implicit for the buyer, is the orientation of Baksi units for complex use. For example, the instructions for using the Baksi gas boiler make it clear that in the case of piping using boilers from the same company, better results will be obtained.
Also, the “gas boiler with Baksi boiler” line provides for a 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 in the fact that the Baksi name has not yet gained wide popularity in the markets of the post-Soviet space.
Almost any model can be found in the offered lines. The device of the Baksi gas boiler implies the use of all three basic 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 imply a joint piping with a boiler. Any of the basic schemes can be implemented:
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 Main series, 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 small room in terms of size and heat output, boilers of the Fourtech series are ideal.
| Model | BAXI Fourtech 24 | BAXI Fourtech 24 F |
| Combustion chamber type | Open, atmospheric | Closed, supercharger |
| Useful heat output, kW | 24 | 24 |
| Minimum productivity, kW | 9,3 | 9,3 |
| Efficiency at maximum performance | 91,20 | 92,93 |
| Efficiency at 30% power level | 89,3 | 90,37 |
| Gas consumption, m3 / h | 2,78 | 2,73 |
| Overall dimensions in mm | 730x400x299 | 730x400x299 |
| Weight, kg | 29 | 33 |
As seen from technical characteristics, with a very compact size of the device and low weight, a good heat output is ensured. For comparison, the closest competitors from VAILLANT, equal in power, have larger dimensions and a third weight higher. The advantage of a unit with a closed combustion chamber is also immediately noticeable. It has lower gas consumption at all power ratings, as well as the best efficiency. When working with a piping with a boiler, financial investments will pay off much faster.
If we talk about problems, it should be noted right away that electronic systems controls ensure safety as much as possible. Technical solutions, embedded in a special algorithm of work, allow you to raise the level of reliability even higher. 
However, some glitches do happen. Individual malfunctions and methods for their solution are given in the instructions for use of the Baksi gas boiler. Typical problems can be identified by the malfunction code on the indicator.
Gas boilers Baksi is reliable equipment, the level of user characteristics of which is quite consistent with the high price. Sophisticated modes of operation guarantee a long service life, and options for using piping with boilers and joint control can provide excellent economic efficiency heating systems in general. Baksi boilers, thanks to the possibility of equipping with sensors and thermostats, can operate without human intervention, providing excellent temperature regime premises.
Dynamic development building technologies allows many of our citizens to acquire own home Outside the city. Owning a small cottage or summer cottage is becoming the norm. Living far from the noisy metropolis, enjoying clean air and peace - this is what attracts people.
V country house, cottage or cottage, as a rule, there is no central heating and hot water supply. This makes it impossible to permanently comfortable stay in such a house in winter period... Without adequate heating in cold weather, the solution would be autonomous system heating.
Autonomous heating does not depend on heating systems. 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.
Comfort, efficiency and reliability of home heating depend on the choice of the boiler. If your house is located in a gasified area, then it makes sense to purchase a gas boiler.
A flow-through gas heater is designed to provide hot water in the house. It was installed earlier in an apartment building. Now the models have been improved and equipped with a gas control and ignition system.
A single-circuit gas boiler is used to heat a small area of housing. It is simple, powerful, but its operation has its own characteristics:
A boiler with an open combustion chamber requires increased care and strict adherence to fire and sanitary requirements. Among the single-circuit boilers there are boilers with a closed combustion chamber, but they are more expensive.
A double-circuit gas boiler is able not only to heat the room, but also to heat the water. One circuit works for water heating, and the second for heating.
The construction and design of Italian gas boilers meet the needs modern heating... The gas boiler "Baksi Luna" can be located on any free spot on the wall. He does not need a special room for placement - everything that he needs for work is already provided for by the internal structure.
All wall-mounted gas boilers "Baksi" undergo mandatory certification for compliance with operational safety requirements. Consumer reviews most often confirm the simplicity of boiler control and its safety.
The units are equipped with a special monitoring system, which is capable of diagnosing the operation of the system itself 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.
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 the installation of an additional boiler. It is possible to heat water in it for household needs.
Single-circuit boilers are quite simple. The burner that ignites the gas was placed inside a safe thermal jacket. The heat accumulated in the combustion chamber is transferred to the heating circuit by means of a heat exchanger.
The material for the manufacture of the heat exchanger is copper, cast iron or steel. This type of boilers is designed for low power - from 14 to 31 kW. Wall-mounted Baxi are small in size, made with a closed or open chamber.
The design of the boiler provides for the presence of a heat exchanger, which is connected to the heating system. Water heating occurs once in a closed cycle. Further, 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 is periodically supplied to it cold water, therefore, he is forced to work constantly for heating.
Types of heat exchangers on Baksi boilers:
Perhaps the most popular and perfect is the Baksi double-circuit gas wall-mounted boiler. Reviews, in any case, are just like that. The model is considered successful and reliable. There are several reasons for this:
The use of such boilers provides significant savings in blue fuel. A turbocharger is built into the system, and this allows you to get the required amount of heat with lower gas consumption. An additional fan is 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 the combustion products. The design is completely sealed and excludes the ingress of harmful toxins and burning into the room.
The principle of their work is based on the laws of physics. Usually gas burns in the boiler chamber and the combustion products are discharged to the outside. In condensation, the procedure is slightly different.
When carbon is burned, carbon dioxide and water vapor are formed. 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.
Large assortment and optimal consumer properties distinguish Baksi gas boilers. Reviews of owners who have installed floor version boilers, testify to their uninterrupted performance. And this is due to the excellent quality of their performance.
Gas floor boilers "Baksi" have a built-in electronic self-diagnosis system, which monitors the operating parameters and, if necessary, adjusts them in the event of a pressure drop in the line.
The Baksi gas boiler works completely autonomously, without any intervention. Errors in the operation of the boiler or a decrease in pressure in the pipeline lead to an operative shutdown of the gas supply to the burner.
Floor standing boilers are produced in several versions. You can choose to fit the needs of your home, summer cottage or industrial premises where it is necessary to maintain a constant temperature, the most suitable gas floor boiler "Baksi". The owners' comments indicate that connection errors are practically excluded, the models are extremely simple. The unit installers will customize them to the homeowner's needs.
The assortment of floor-standing gas boilers "Baksi":
The principle of operation is the same as for wall-mounted boilers. On the heat exchanger, the process of reverse transformation of the dispersed part into liquid is underway. During the transition, additional energy is released, which significantly increases the energy consumption of the boiler.
The gas boiler "Baksi" provides a separate source for ignition of the burner. The units are used in different conditions... To increase the safety of using the unit, a Baksi atmospheric gas boiler was manufactured. The instruction prescribes to install it in a place where it is possible to connect a chimney, gas pipe, heating and water supply systems.
V atmospheric boilers The thermocouple controls the uninterrupted operation of the product. The dependence of the boiler on energy carriers is excluded, and if the burner flame goes out, the inlet valve closes. With such a device, it was possible to increase the safety of operation of a gas boiler.
Gas floor boilers "Baksi", which have two independent circuits, will heat the house and prepare hot water. Thermal energy, which is generated, is spent on maintaining the already obtained heat transfer mode. The periodic flow of cold portions of water makes the boiler constantly work for heating.
Gas boiler "Baksi Slim" compact, independent of electricity. It is made of cast iron, has an atmospheric burner and automatic equipment that will secure the use of the unit by shutting off the gas valve. In the model line, the gas boiler "Baksi Slim" is represented by 5 varieties. They differ in power.
There may be malfunctions that disable the Baksi gas boiler. The installation instructions must always be followed.
Problems may arise with the boiler when installing an incorrectly selected chimney. Specialists insist on installing a coaxial chimney, which is also produced by Baksi.
However, if you already have a proven reliable chimney, and you do not doubt its serviceability, then it is possible to connect to it. This will save the owner some money.
Easy to maintain Baksi 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 set up the Baksi gas boiler yourself. The operating instructions are simple, and the information LCD panel will give a comprehensive picture of the settings. The consumer can set the power himself, it is necessary to set the desired program and set the required minimum and maximum values.
A self-diagnosis system is built into the Baksi gas boiler. He himself can not only identify a breakdown, but also fix it in a short time. The display shows all the information to adjust and set the pressure in the system and the temperature of the water.
Any technique is prone to breakdowns, but everything is compared in percentage terms. Judging by the owners' reviews, Baksi gas boilers have quality, ease of control, are fully automated and do not require complicated maintenance.
If complaints do arise, then the breakdowns are insignificant and they do not always occur due to the poor-quality performance of the boiler itself. It is necessary to monitor the draft in the chimney so that it does not fail. Scale on the heat exchanger is possible, but this can also be quickly corrected.
Italian gas boilers "Baksi" receive positive reviews from users on a regular basis. They have established themselves in the market as safe, productive and environmentally friendly, possess modern design and high-tech automation, fully meet the expectations of buyers and will not disappoint discerning users.
Wall mounted gas boilers Baxi literally overwhelmed Russian market heating equipment over the past decade. This is not surprising. When a potential buyer is faced with a choice: to buy an inexpensive boiler, but unfinished and domestic, or reliable, but expensive, made in Germany, then the choice is often made in favor of Italian manufacturers of gas boilers.
As a rule, they are distinguished by a rather good price-quality ratio and a developed network. Maintenance parts are easy to find. Consider the most popular brand of gas boilers in Russia Baxi, 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 (hinged) single-circuit and double-circuit gas boilers Baksi, identify their main advantages and disadvantages, and also figure out how they differ from each other according to the instruction manual.
Basic models of wall-mounted gas boilers from Baxi
The following models of wall-mounted gas boilers are presented on our market from Baxi:
- 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 counterpart 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 removal 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 the combustion products from the boiler are forcibly removed into the atmosphere. To do this, you will have to additionally buy coaxial chimney, or a pipe system for separate smoke exhaust and air intake.
The coaxial chimney type "pipe-in-pipe" is installed at one end (through the elbow) on the boiler, and the other end through the wall goes to the street. This is very convenient because there is no need to specially fence the chimney through the roof.
Such models at Baxi are designated by the article number "F" or "Fi". For example, the wall-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 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 also 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 chimneys of the same diameter can be used. True, this version of the chimney will cost a little more.
In these models, there is no turbine, and in the marking of the Baksi boiler there is an article "i", or it is not affixed at all. For example, "Baxi Eco Four 24i" or "Baxi Four Tech 24".
Wall mounted gas boilers Baxi are available in two versions:
1. Single-circuit.
This type of boilers provides only for heating the heating medium in the heating system. These boilers have only one main heat exchanger. This type of boilers 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, perhaps after some time, the second circuit of this boiler will also come in handy, and you will not have to buy a new device.
2. Double-circuit.
Such boilers are most popular with buyers, as evidenced by numerous reviews on 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 utility water, 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 bithermal one for heating both circuits in one monolithic block. Boilers of this type are in the greatest demand among potential buyers. Having bought such a boiler, we get in "one bottle" both a boiler for heating and a gas water heater for hot water supply.
Features of the device of double-circuit gas boilers Baxi: instruction
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 from German manufacturers, either Grundfos or Wilo. This pump is capable of lifting a column of water in heating system up to 6 meters, which is quite enough for two-storey house or a cottage. The circulation pumps built into the boilers are quite economical and 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 with a volume of 6-10 liters. You do not need to buy an additional one if the total volume of water in the system does not exceed 100-150 liters. You can also find out this individual volume yourself by counting the total number of radiator sections, pipe length or when filling the system.
4. Baxi boilers are equipped with a Honeywell gas valve, gas-burner has stainless steel flame diffusers. 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.
Let's consider the device of a double-circuit gas boiler using the example of the "Baxi Eco Four 24F" model according to the scheme:
1 - hydraulic pressure switch
2 - three-way valve
3 - three-way valve motor
4.22 - 3 Bar safety valves
5 - Honeywell gas valve
6 - pipe for gas supply to the burner
7 - water temperature sensor in the system
8 - flame spark plug
9 - overheating protection sensor (thermostat)
10 - main heat exchanger
11 - smoke hood
12 - turbine for exhaust of combustion products
13 - Venturi tube
14.15 - points of position. and neg. pressure
16 - traction control sensor
17 - gas burner
18 - expansion membrane tank
19 - circulation pump
20.21 - drain cock and pressure gauge
23 - tap for feeding the heating system
24.25 - DHW temperature sensors
In addition, an electronic board is built into the wall-hung boilers, the so-called. "Brains" of the boiler, various sensors: flow rate, 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 circulation pump... That does not negate the mandatory purchase of a voltage stabilizer for a boiler of this brand.
Baksi gas boilers: model differences and technical characteristics
As you can see, the lineup boilers from this Italian manufacturer are 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 models of boilers of the Baxi Main Four and Baxi Main 5 series
The predecessor of the boilers of this series was the apparatus 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 "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 circuit and the DHW circuit are heated in the same heat exchanger. In this case, the water in the circuits is not mixed, and the running water is heated precisely by the heating circuit.
Fifth generation boiler Baxi Main 5 attracts with its compact size, but it is produced only with a closed combustion chamber, in contrast to 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.
Features of the models of boilers Baxi Eco Four and Baxi Eco Compact
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 the water only in the heating circuit, and the secondary works independently of it, using the heat carrier from the heating circuit to heat the running water. Thus, the load on the main heat exchanger is significantly 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 the better arrangement of internal elements, in comparison 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 series Baxi Eco 3 Compact.
Features of models of gas boilers Baxi Four Tech
Boilers series Baxi four tech Is a cheaper version of the Eco Four series boilers. They are also equipped with two separate copper and stainless steel heat exchangers. Their distinctive feature is that the hydraulic part (water supply pipes) are not made of copper, as in Eco Four, but 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 exchange rate of the dollar and the euro.
Additional functions and boiler operation control
All models are equipped with a digital control panel, on which you can set the operating mode of the boiler, the temperature of the water in the heating system and hot water supply, 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 the weather-dependent automation, by connecting a special outdoor temperature sensor.
Or buy a room thermostat for the Baxi boiler and set the room temperature.
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 during the operation of the Baxi boiler under certain codes, for example, "E 06" - the DHW temperature sensor is faulty, etc.
Advantages of wall-mounted gas boilers Baxi
- a wide range of models;
- lots of service centers in Russia and CIS countries;
- availability of spare parts for official representatives(dealers);
- acceptable cost.
Disadvantages of Baxi boilers
- weak electronics (in particular, electronic board);
- high sensitivity to poor quality running water;
- not "native" spare parts.
Outcomes
Today we have disassembled in detail the wall gas boilers Baxi, considered the advantages, disadvantages of the models, their technical characteristics, according to the instruction manual. We also compared the difference between the main models of this brand of boilers and made our own review on them.
I will not recommend or dissuade you from buying, the choice is yours. Read reviews on gas boilers Baxi and analyze. I will only say that the price-quality ratio for Baksi boilers is quite good, even despite the fierce competition in the heating equipment market. We watch the video review.

The Baksi gas boiler works completely autonomously, without any intervention. Errors in the operation of the boiler or a decrease in pressure in the pipeline lead to an operative shutdown of the gas supply to the burner.
Floor standing boilers are produced in several versions. You can choose the most suitable gas floor boiler "Baksi" for the needs of your home, summer cottage or industrial premises, where it is necessary to maintain a constant temperature. The owners' comments indicate that connection errors are practically excluded, the models are extremely simple. The unit installers will customize them to the homeowner's needs.
The assortment of floor-standing gas boilers "Baksi":
The principle of operation is the same as for wall-mounted boilers. On the heat exchanger, the process of reverse transformation of the dispersed part into liquid is underway. During the transition, additional energy is released, which significantly increases the energy consumption of the boiler.
A separate source is provided for ignition of the burner in the Baksi gas boiler. The units are used in various conditions. To increase the safety of using the unit, an atmospheric gas boiler "Baksi" was manufactured. The instruction prescribes to install it in a place where it is possible to connect a chimney, gas pipe, heating and water supply systems.
In atmospheric boilers, a thermocouple controls the uninterrupted operation of the product. The dependence of the boiler on energy carriers is excluded, and if the burner flame goes out, the inlet valve closes. With such a device, it was possible to increase the safety of operation of a gas boiler.
Floor-standing gas boilers "Baksi", which have two independent circuits, will heat the house and prepare hot water. The heat energy that is generated is spent on maintaining the already obtained heat transfer regime. The periodic flow of cold portions of water makes the boiler constantly work for heating.
Gas boiler "Baksi Slim" compact, independent of electricity. It is made of cast iron, has an atmospheric burner and automatic equipment that will secure the use of the unit by shutting off the gas valve. In the model line, the gas boiler "Baksi Slim" is presented in 5 varieties. They differ in power.
There may be malfunctions that disable the Baksi gas boiler. The installation instructions must always be followed.
Problems may arise with the boiler when installing an incorrectly selected chimney. Specialists insist on installing a coaxial chimney, which is also produced by Baksi.
However, if you already have a proven reliable chimney, and you do not doubt its serviceability, then it is possible to connect to it. This will save the owner some money.
Easy to maintain Baksi 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 set up the Baksi gas boiler yourself. The operating instructions are simple, and the information LCD panel will give a comprehensive picture of the settings. The consumer can set the power himself, it is necessary to set the desired program and set the required minimum and maximum values.
A self-diagnosis system is built into the Baksi gas boiler. He himself can not only identify a breakdown, but also fix it in a short time. The display shows all the information to adjust and set the pressure in the system and the temperature of the water.
Any technique is prone to breakdowns, but everything is compared in percentage terms. Judging by the owners' reviews, Baksi gas boilers have quality, ease of control, are fully automated and do not require complex maintenance.
If complaints do arise, then the breakdowns are insignificant and they do not always occur due to the poor-quality performance 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" receive positive reviews from users on a regular basis. They have proven themselves in the market as safe, productive and environmentally friendly, have a modern design and high-tech automation, fully meet the expectations of buyers 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, which has an open chamber.
The company installs both steel and copper heat exchangers in its units.
The latter, due to their high thermal conductivity, are more efficient.
The successful design of the heat exchanger allows you to assimilate 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 in the Baksi heater, there can be another one intended for preparing hot water. Such boilers are called double-circuit. Some models, for example, Baksi Ekofor 24, can heat water in an external boiler.
A strainer is installed at the inlet to the heat exchanger.
For different models, the volume of this element can be 8 or 10 liters.
All units of this brand are equipped with volatile automation. The total power consumption of the boiler, depending on the model, is 135 or 165 W. Most of the models, for example, Luna-3, Eco-3, Slim, Nuvola, are weather-dependent.
This means that in addition to a timer and a room thermostat, an outdoor temperature sensor can be connected to it. Accounting weather conditions allows the system to switch the boiler to the optimal mode in a timely manner, which makes the heating system more economical.
V wall 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 provides for heating the coolant to 85 degrees at a temperature in the "return" of about 30 degrees. The second is designed for a temperature ratio of 45/30 degrees (supply / return) and is intended for floor heating systems. Also, this mode can be used with normal radiator heating during the off-season.
So, consider the Baksi gas boiler - operating instructions, setting and adjustment. To set up the boiler, it is enough to 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 thermostats with a programming function, through which you can plan the boiler operation schedule for a day or a week in advance (depending on the model).
In boilers of the Luna-3 Comfort series, the controller is removable and can control the operation of the boiler remotely. It looks like a panel with a display and keys, in which the room temperature sensor is also "wired".
The controller is placed in one of the rooms at any convenient place and with its help the operation of the heater is adjusted. On it, you can also view the results of self-diagnostics and view, if necessary, 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 mains through a stabilizer. Imported electronics are designed for high quality power supply and with a significant deviation of its parameters from the norm, which is still observed quite often in our country, it easily breaks down.
With a certain frequency (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 metal bristle brush. For the cleaning copper heat exchanger such a tool is not suitable as it could damage it. It is better to use a metal scouring pad.
The DHW heat exchanger should be cleaned from time to time with a descaling agent. The same must be done with the main heat exchanger, if ordinary water that has not undergone the desalination procedure is used as a heat carrier.
The fan must be lubricated periodically, otherwise the motor will not be able to rotate it at a sufficient speed over time. Unscrew the back of the assembly and remove the stator, after which you will need to pour a few drops of engine oil inside.
The TM Baksi boilers have a self-diagnosis function, thanks to which these units independently identify their own faults. The test results are displayed as an alphanumeric code. Each code indicates several possible malfunctions. Below are the most common ones.
Overheating can be caused by scale clogging of the heat exchanger, breakdown of the circulation pump, clogged filter or the appearance of an air lock in the heating circuit.
False alarms of the system are possible due to a breakdown of the thermal sensor or its insufficient contact with the coolant (should be installed on thermal paste).
The chimney is clogged with soot or condensate, is too long or has an incorrect design (for example, there is no mandatory vertical section at the beginning, which has a length of at least 2 diameters). Be sure to check the fan for performance.
It is triggered by multiple (more than 6 times) short-term burner damping. Check if flue gases are leaking into the duct. Also, the reason may be voltage drops.
The error appears when this sensor fails or when its contact with the board is broken.
If this sensor signals a gradual or sharp decrease in the temperature in the DHW circuit, the 3-way valve may be out of order.
It is checked as follows:
This message is displayed mainly due to a breakdown of the circulation pump or a blockage in the heating circuit. The filter and heat exchanger are more susceptible to this (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 summarized in a short list.
Another advantage, which is somewhat implicit for the buyer, is the orientation of Baksi units for complex use. For example, the instructions for using the Baksi gas boiler make it clear that in the case of piping using boilers from the same company, better results will be obtained.
Also, the “gas boiler with Baksi boiler” line provides for a 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 in the fact that the Baksi name has not yet gained wide popularity in the markets of the post-Soviet space.
Almost any model can be found in the offered lines. The device of the Baksi gas boiler implies the use of all three basic engineering solutions:
Among the equipment suitable for heating an apartment or a 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 imply a joint piping with a boiler. Any of the basic schemes can be implemented:
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, 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 that operate on different principles. Boilers of the Fourtech series are ideal for a small room in terms of size and heat output.
| Model | BAXI Fourtech 24 | BAXI Fourtech 24 F |
| Combustion chamber type | Open, atmospheric | Closed, supercharger |
| Useful heat output, kW | 24 | 24 |
| Minimum productivity, kW | 9,3 | 9,3 |
| Efficiency at maximum performance | 91,20 | 92,93 |
| Efficiency at 30% power level | 89,3 | 90,37 |
| Gas consumption, m3 / h | 2,78 | 2,73 |
| Overall dimensions in mm | 730x400x299 | 730x400x299 |
| Weight, kg | 29 | 33 |
As can be seen from the technical characteristics, with a very compact size of the device and low weight, good heat energy output is ensured. For comparison, the closest competitors from VAILLANT, equal in power, have larger dimensions and a third weight higher. The advantage of a unit with a closed combustion chamber is also immediately noticeable. It has lower gas consumption at all power ratings, as well as the best efficiency. When working with a piping with a boiler, financial investments will pay off much faster.
If we talk about problems, it should be noted right away that electronic control systems maximize security. Technical solutions incorporated in a special algorithm of work allow to raise the level of reliability even higher. 
However, some glitches do happen. Individual malfunctions and methods for their solution are given in the instructions for use of the Baksi gas boiler. Typical problems can be identified by the malfunction code on the indicator.
