Baksi boiler wall-mounted instruction manual. Step-by-step instructions for operating the Baxi gas boiler: from installation to self-configuration and first start. Wall-mounted boilers with one circuit

wall gas boilers Baxi literally flooded Russian market 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 network. Maintenance, 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

Our market has following models wall-mounted gas boilers from Baxi:

- 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 closed camera combustion

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.

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 on dual 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 lift a column of water in 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 equipped.

3. To maintain required pressure in the heating system, Baksi boilers have a built-in membrane expansion tank 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, gas-burner It 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 a dual-circuit device gas boiler on the example of the model "Baxi Eco Four 24F" according to the scheme:

The device of a double-circuit gas boiler Baxi

1 - hydraulic pressure switch

2 - three-way valve

3 - three-way valve motor

4,22 — safety valves for 3 bars

18 - expansion membrane tank

19 - circulation pump

20,21 — drain tap and pressure gauge
23 - tap for feeding the heating system
24.25 - temperature sensors of the DHW circuit

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 circulation pump. Which does not cancel the mandatory purchase for a boiler of this brand.

Baksi gas boilers: model differences and technical specifications

As we see, the lineup boilers in 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 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. Them distinctive 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” - faulty temperature sensor DHW, 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 official representatives(dealers);
- reasonable cost.

Disadvantages of Baxi boilers

- weak electronics (in particular, an electronic board);
- high sensitivity to running water Bad quality;
— not "native" spare parts.

Independent heating system

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, in 5 years, equipment for autonomous heating pays off in full.

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.

Types of boilers

To provide hot water in the house is called flowing gas heater. It was previously installed in 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 \u200b\u200bhousing. It is simple, powerful, but its operation has its own characteristics:

the need to connect to the chimney;
use for combustion of the internal air of the room (open combustion chamber);
need for additional ventilation.

A boiler with an open combustion chamber requires extra care and strict adherence to fire 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 is able not only to heat the room, but also to heat the water. One circuit works for heating water, and the second - for heating.

Wall-mounted gas boilers "Baksi"

The construction and design of Italian gas boilers meet the needs modern heating. The gas boiler "Baksi Luna" can be placed on any free space on the wall. It does not require a special room for accommodation - everything that it needs for work is already provided for by the internal structure.

All Baksi wall-mounted gas boilers undergo mandatory certification for compliance with operational safety requirements. Consumer reviews most often confirm the ease of controlling the boiler and its safety.

The units are equipped with a special control 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 in any way.

The range of wall-mounted gas boilers "Baksi"

Gas single-circuit boiler - only for heating the house.
Household wall-mounted gas boiler with two circuits; purpose - heating and hot water supply.
Turbocharged boiler with two circuits. Special equipment increases the speed of internal processes - for heating and hot water.
Gas wall-mounted condensing boiler uses the released steam energy until it turns into water.

Wall-mounted boilers with one circuit

Single-circuit gas heating boilers are designed for heating the house. They decided to make wall-mounted "Baksi" more functional and installed special outlets for installing an additional boiler. It is possible to heat water for household needs.

Single-circuit boilers are arranged quite simply. The burner, which ignites the gas, was placed inside a safe thermal envelope. The heat that accumulates 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 boiler is designed for low power - from 14 to 31 kW. Wall-mounted Baxi are small in size, made with a closed or open chamber.

Double-circuit wall-mounted gas boilers

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 periodically enters it cold water, so he has to work constantly for heating.

Types of heat exchangers on Baksi boilers:

Lamellar. Copper plates are soldered onto a long curved steel tube. To protect the structure from high temperature, a special protective layer was applied to it.
Biometric. Another pipe of smaller diameter is inserted inside the pipe. Water for heating flows in the outer one, water for household needs moves through the inner one.

Gas boiler Baxi Luna 3 Comfort

Perhaps the most popular and perfect is the Baksi double-circuit gas wall-mounted boiler. Reviews, in any case, are just that. The model is considered successful and reliable. There are several reasons for this:

A weather-dependent automatic system has been installed.
Temperature regime for heating radiators (30-85° C) and separately for water floor heating (30-45° C).
Self-diagnostics with memory of the last malfunctions and malfunctions.
The LCD display reflects all the necessary operating parameters.
The heat exchanger has an anti-corrosion coating.

Wall-mounted double-circuit turbocharged boilers

The use of such boilers provides significant savings in natural gas. A turbocharger is built into the system, and this allows you to get the required amount of heat with lower gas consumption. The boiler is additionally equipped with a fan that pumps 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 the ingress of harmful toxins and burning inside the room.

Condensing wall-mounted boilers

The principle of their work is based on the laws of physics. Usually, gas is burned in the boiler chamber, and the combustion products are discharged to the outside. In condensation, a slightly different procedure.

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 is much higher than that of simple gas boilers.

Advantages of wall-mounted boilers according to consumer reviews

Boilers "Baksi" with two circuits, for all their small size, are able to cope with space heating and water heating in uninterrupted mode.
Heating of water occurs in the flow mode, and not in the boiler. It is much more convenient and economical.
The boiler is fully operational automatic mode. The user does not need to waste time on controlling the working process of the boiler.
By choosing a wall-mounted gas boiler "Baksi", you do not need to buy additional related equipment. All that is needed for battery life boiler, provided for by its design.
Unit dimensions are minimal. It does not take up much space, so it is more often installed in the kitchen, where it matches the size of the wall cabinets.
If the Baksi gas boiler is correctly installed, errors in its operation are practically eliminated. It is reliable, efficient, safe and relatively inexpensive.

The main characteristics of wall-mounted gas boilers "Baksi"

There is a constant modulation of the flame. This improves efficiency and saves gas.
In winter, at low temperatures, when the gas pressure drops to 5 mbar, the device operates smoothly.
It is enough to change the jets and re-adjust gas automation boiler - and it will switch from natural gas to liquefied gas.
Stainless steel was used for the material of the burners, and this significantly increased their service life.
A filter is installed at the cold water inlet.
You can install a room thermostat or mode programmer.
The maximum pressure in the heating system is 3 bar, in the DHW circuit - 8 bar.

Gas floor boilers "Baksi"

Large assortment and optimal consumer properties distinguish gas boilers "Baksi". Feedback from owners who have installed floor version boilers, testify to their uninterrupted performance. And this is due to the excellent quality of their workmanship.

Gas floor-standing boilers "Baksi" have a built-in electronic self-diagnosis system that monitors operating parameters and, if necessary, adjusts them in the event of a pressure drop 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 the prompt shutdown of the gas supply to the burner.

Floor boilers are produced in several versions. You can choose according to the needs of your home, cottage or production premises, where it is necessary to maintain a constant temperature, the most suitable gas floor boiler "Baksi". Owner reviews indicate that connection errors are practically excluded, the models are extremely simple. Unit installers will customize the units to meet the needs of the homeowner.

The range of floor gas boilers "Baksi":

Single boilers.
Double boilers.
atmospheric boilers.
Condensing boilers.

Condensing gas boilers "Baksi"

The principle of operation is the same as that of wall-mounted boilers. On the heat exchanger, the process of inverse transformation of the dispersed part into a liquid takes place. During the transition, additional energy is released, which at times increases the energy intensity of the boiler.

Atmospheric floor boilers with one circuit

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, an atmospheric gas boiler "Baksi" was made. The instruction prescribes to install it in a place where it is possible to connect a chimney, gas pipe, heating and water supply systems.

AT atmospheric boilers a thermocouple controls the smooth 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 this device, it was possible to increase the safety of operation of a gas boiler.

Atmospheric floor standing boilers with two circuits

Gas floor-standing boilers "Baksi", having two independent circuits, will heat the house and prepare hot water. Thermal energy, which is produced, is spent on maintaining the already obtained heat transfer mode. The periodic flow of cold portions of water makes the boiler constantly work on heating.

Gas boiler "Baksi Slim"

The gas boiler "Baksi Slim" is compact, independent of electricity. It is made of cast iron, has an atmospheric burner and automation that will secure the use of the unit by shutting off the gas valve. In the model line, the Baksi Slim gas boiler 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 the wrong chimney. Profile specialists insist on installing a coaxial chimney, which is also manufactured 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 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 easily set up the Baksi gas boiler yourself. The control instruction is simple, and the information LCD panel will give a comprehensive picture of the settings. The consumer can set the power himself, you need to set 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 system pressure and water temperature.

Safe and reliable gas boilers "Baksi". Consumer reviews

Any technique is prone 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 operate, fully automated and do not require complex maintenance.

Complaints, if they arise, then the breakdowns are insignificant and they do not always occur due to 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. Scale on the heat exchanger is possible, but this can also be quickly fixed.

Instructions for choosing a gas boiler "Baksi"

Be sure to ask about the warranty period that is issued when buying a boiler.
A wall-mounted boiler with a power of 11-42 kW is suitable for heating a house up to 400 square meters. m. For the price, it will be almost half cheaper than the floor. This is due to the design of the boiler.
If the cottage area allows, and the boiler can be installed in a separate room, then the choice can be stopped on boilers with an open combustion chamber.
The closed combustion chamber of the boiler is designed for living rooms. Oxygen is taken in through a carbon fiber chimney. Forced or additional ventilation not required.

Device and main elements

In terms of their design, TM Baksi units are not much different from other gas boilers. They consist of several components.

Gas burner device

This node contains several elements:

Gas-burner: in the most affordable models, a burner with a constant power is installed, in more expensive ones - with step regulation. To maintain a constant temperature in the room, the automation system has to periodically extinguish such burners, and then ignite them again. In the most expensive Baksi boilers, modulating burners are installed, the power of which is smoothly regulated. Such burners operate constantly and in the most optimal mode, so the set temperature is maintained with high accuracy.
Combined gas valve: allows or blocks the gas supply to the burner, depending on the signals from the automation devices.
Ignition block: consists of an electronic circuit and an electrode. This unit converts the mains voltage supplied to it into high-frequency high-voltage pulses that are applied to the electrode. As a result, a spark flares up between the electrode and the burner (in some models, between two electrodes), igniting the gas-air mixture on the burner.

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.

heat exchanger

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 assimilate 90.8% of the heat generated in the combustion chamber (for some models, the efficiency is slightly less - 88.7%).

In addition to the main heat exchanger, the Baksi heater may contain another one designed for preparing hot water. Such boilers are called double-circuit. Some models, for example, Baksi Ecofor 24, can heat water in an external boiler.

A mesh filter is installed at the inlet to the heat exchanger.

Expansion tank

Different models have volume given element can be 8 or 10 liters.

Automation system

All units of this brand use volatile automation. The total power consumption of the boiler, depending on the model, is 135 or 165 watts. For most models, for example, Luna-3, Eco-3, Slim, Nuvola, the automation is weather-dependent.

This means that in addition to the timer and room thermostat, you can connect an outdoor temperature sensor to it. Accounting 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.

Operating modes

Boilers TM Baxi can operate in two modes:

standard;
low temperature.

The first involves 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 "warm floor" systems. Also, this mode can be used with conventional radiator heating during the off-season.

Setting and adjustment

So, consider the Baksi gas boiler - operating instructions, settings and adjustments. To set up the boiler, it is enough to set the desired temperature on the room thermostat - the unit will do the rest. All data is shown on the display. The most convenient are thermostats with a programming function, through which you can plan the boiler's work 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 “sewn up”.

The controller is placed in one of the rooms at any convenient place and with its help the heater is adjusted. On it you can also get acquainted with the results of self-diagnosis and, if necessary, view a list of the latest errors - it is stored in memory.

Prevention

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 we still observe quite often, it easily fails.

With a certain frequency (after several years of operation), the heat exchanger from the outside must be cleaned of soot. If it is made of stainless steel, you can use a special brush with metal bristles. Such a 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 must be flushed from time to time with some kind of descaling agent. The same must be done with the main heat exchanger if ordinary water is used as a heat carrier that has not undergone a desalination procedure.

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 engine oil inside.

Errors during operation

TM Baxi boilers have a self-diagnosis function, thanks to which these units independently identify their own malfunctions. The test results are displayed as alphanumeric code. Each code refers to several possible faults. Below are the most common ones.

Error E01 (flame control sensor tripped)

When the boiler was connected to the mains, the phase and the neutral core were reversed, as a result of which the boiler could not turn on (relevant for phase-dependent models, for example, Main 24 Fi and Main For). The power cable must be connected correctly.
The burner cannot develop sufficient power. Causes: breakdown of the gas valve or diode bridge, lack of air (smoke can seep into the air intake tract), as well as incorrect pressure settings in the heating circuit.
The gas pressure has dropped or its lower threshold has been incorrectly set. If the pressure drop occurs frequently, the lower limit in the settings should be set to 5 mbar. With such a malfunction, the boiler turns off immediately after starting, and when it is turned on, pops may be heard.
Defective flame control sensor or ignition unit.

E02 (coolant overheating sensor)

The cause of overheating may be clogging of the 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 on thermal paste).

E03 (traction sensor)

The chimney is clogged with soot or condensate, is too long or has an incorrect design (for example, the required vertical section at the beginning is missing, having a length of at least 2 diameters). Be sure to check the fan for performance.

E04 (flame tracking electrode)

Triggered by repeated (over 6 times) short-term attenuation of the burner. It is necessary to check whether flue gases are leaking into the duct. It could also be due to voltage fluctuations.

E05 (heat carrier temperature sensor)

The error appears when this sensor fails or if its contact with the board is broken.

E06 - appears when the temperature sensor of the water heating circuit malfunctions (in double-circuit boilers)

If this sensor indicates a gradual or sharp decrease in temperature in the DHW circuit, the 3-way valve may have failed.

It is checked as follows:

turning off the boiler, they wait for the coolant to cool completely in pipes and radiators;
cut off the heating circuit with the help of valves;
start the boiler in the water heater mode;
check the temperature of hot water in the DHW circuit and the coolant: if the medium in both circuits is heated, the 3-way valve must be changed.

E10 (minimum coolant pressure switch)

Such a message is displayed mainly due to a breakdown of the circulation pump or a clogged heating circuit. AT more the filter and the heat exchanger are subject to this (overgrown with scale).

Features of these systems

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.

The flame is always adjustable. The boiler does not just ignite - the launch is carried out in two stages. First, the burner warms up the combustion chamber, operating at minimum power for approximately 60 seconds, then goes to the level set by the electronic control unit.
If temperature control sensors are used, automation only supports required level flame. This provides smoother operation, reduces the number of mode switching cycles. As a result, the boiler lasts longer due to less wear on nozzles, combustion chamber walls, blowers, and coils.
The post-circulation system, controlled by signals from external sensors, can significantly reduce fuel and electricity consumption. The boiler will continue to circulate the coolant after the burners are turned off, until a signal is received to reduce the temperature balance.
Baxi boilers support double temperature control. It is possible to control the operation of automation not only with the help of sensors installed indoors, but also located on the street. This makes it possible to maintain an optimal balance of humidity and the best climatic conditions in the rooms.
The equipment is quite compact compared to competitors, weighs little. Connecting Baksi gas boilers is as convenient as possible, carried out according to standard schemes for both wall and floor models. This makes it possible to minimize the malfunctions of Baksi gas boilers that occur due to improper operating conditions. You can use the equipment with any options for organizing the strapping.

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 Baxi boiler" lines provide for a direct connection electronic circuits regulation to create a flexible control system. If we talk about the shortcomings of boilers of this brand, the following points can be noted.

High price. Compared to the closest competitors on the market, the equipment has a 2-2.5 times higher price. This is easily explained by the manufacturability of work, as well as best performance ventilation of combustion chambers, the stability of maintaining the climate in the room.
Floor boilers are very sensitive to installation. Incorrect installation or location can cause various deviations, among which are increased noise, ignition with cotton, and others. It almost does not affect the main parameters of work, but it causes concern.

The high price in the eyes of potential buyers is a key factor in the fact that the Baksi name has not yet become widely known in the post-Soviet markets.

Designs and executions

In the proposed lines you can find almost any model. The Baksi gas boiler device involves the use of all three main engineering solutions:

with an open combustion chamber;
with forced supercharging and a closed combustion chamber;
with condensation system.

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 involve joint piping with a boiler. You can implement any of the basic schemes:

connection of a double-circuit boiler to work with a boiler as a buffer for the heating system;
using the boiler to ensure the operation of the hot water supply system through the three-way avk valve of the air boiler;
connection of the heater through an additional control system in order to realize the maximum rate of hot water withdrawal from the system;
the use of a boiler as a heat accumulator, both for the heating system and hot water supply.

Some characteristics of equipment suitable for apartment heating.

Most interesting to residents apartment buildings, as well as owners of small cottages and private houses wall boilers Main, ECO Compact, Fourtech series. These boilers are compact in size, do not have any special requirements for installation, 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 dimensions and indicators of thermal power, boilers of the Fourtech series are ideal.

Model	BAXI Fourtech 24	BAXI Fourtech 24 F
Combustion chamber type	open, atmospheric	Closed, supercharger
Useful heat transfer, 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 specifications, with very compact dimensions of the device and low weight, a good return of thermal energy is ensured. For comparison, the closest competitors from VAILLANT, equal in power, have large dimensions and a third more weight. The advantage of a unit with a closed combustion chamber is also immediately noticeable. It has lower gas consumption in all power ratings, as well as better efficiency. When working with a piping with a boiler, financial investments will pay off much faster.

Malfunctions and methods for their solution

If we talk about problems, it is worth noting right away that electronic control systems provide maximum security. Technical solutions, embedded in a special algorithm of work, allow you to raise the level of reliability even higher.

However, some crashes do happen. Individual malfunctions and methods for solving them are given in the instructions for using the Baksi gas boiler. Common Problems, can be determined by the fault code on the indicator.

Up

Baksi gas boilers are reliable equipment, the level of user characteristics of which is fully consistent high price. Thoughtful operating modes guarantee a long service life, and options for using boiler piping and joint control can provide excellent economic efficiency for the heating system as a whole. Baksi boilers, thanks to the possibility of being equipped with sensors and thermostats, can work without human intervention, providing excellent room temperature conditions.

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 Baksi double-circuit wall-mounted gas boiler, purchase the necessary tools, then no one will give you permission to perform such work. It is important to know that the installation, and even more so the connection of gas equipment, should be carried out only by experienced craftsmen who are able to do everything in compliance with the requirements and rules.

Upon completion of all work, the master will without fail perform the first start of the Baxi gas boiler, which will allow you 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 and floor heating boilers, as well as carefully study the device of the Baxi gas boiler - this will allow you to properly operate the equipment in the future.

Proper installation of a wall-mounted gas boiler

Preparatory work

First of all, we open the packaging of the device and check the equipment, 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 combustible materials, it is necessary to fix a heat-resistant coating on the surface, and in this case the device is mounted from the surface at a distance of up to 5 cm.

Note that the installation of the Baxi gas boiler with your own hands at this stage can be performed, since preparatory work may not be the responsibility of professionals. Their task is exclusively connection and installation.

Before installing the device, it is recommended to flush the inner tubes, which could get into small debris and dust during transportation and storage in the warehouse. Only after completing these works, you can proceed with the installation process, which includes eight stages.

Before starting all work, check the number indicated in the passport with the number on gas appliance to be installed. This point should be checked before buying. If the numbers do not match, the boiler may not be registered.

Installation of a wall-mounted gas boiler Baksi

Install planks.
On the water pipe through which water will be supplied, a filter is installed. If this is not done, the equipment will become clogged, and you will need to buy spare parts for Baxi gas boilers and call the master to fix the problem. The filter must be installed between two shut-off taps - this will allow it to be replaced or cleaned without draining water from the system.
A coaxial chimney is installed for the Baksi gas boiler, after which the draft is checked.
The gas boiler is connected to the pipeline using a coupling, the connection is made from the side.
Feed connects at the top, return at the bottom. If you need to perform welding work, it is recommended to use gas welding. The slope of heating pipes should not exceed 5 mm per 1 meter of pipe.
The connection of the appliance to the gas supply system must be carried out by a specialist.
If the installed equipment is volatile, then we connect it to the mains. It is important to install a voltage stabilizer for the Baxi gas boiler, the presence of which will protect the device from power surges, short circuits and overheating.
After connecting all the circuits, the master performs the first start and checks the quality of the gas boiler installed by him in the heating system.

If necessary, in order to increase the efficiency and profitability of the device, the master can recommend installing a room thermostat for the Baxi gas boiler, which will allow you to adjust the heating temperature of the coolant based on room temperature parameters

Installation of a floor gas heating boiler

We check the completeness and compliance of the numbers in the passport and on the equipment. After that, attention switches to the room in which the equipment is planned to be installed.

If there is no desire to frequently repair Baksi gas boilers, it is recommended to trust the installation and connection to specialists.

The surface on which the installation will be performed must be perfectly flat. It is recommended to put a sheet of metal on the floor surface, which should protrude beyond the design of the device by at least 10 centimeters, and from the front side by 30 cm.

Unit installation

The chimney is being installed and the draft is being checked.
Connecting the boiler to the heating system, on the return before entering the boiler, a shut-off valve is installed, then a filter.
Connecting the water supply to the instrument circuit. Before the equipment, a filter is placed on the pipe, followed by a shut-off valve. The filter is installed in order to prevent clogging of the pipeline located in the design of the device. Shut-off valves installed on both sides will be needed when Baxi gas boilers are being repaired or serviced. The advantage is that it will not be necessary to drain the coolant from the system: they simply turned off the taps and you can carry out the necessary work.
The final step is to connect the device to the gas pipeline, after which you can perform the first start. All work related to the connection must be carried out only by a specialist.

Provided that the installation of the Baksi gas boiler was carried out by a qualified specialist, it will be possible to speak with confidence about the quality of all connections and that the device will last a long time and work properly for many years. Of course, the latter will depend only on how correctly the gas heating boiler will be operated. Note that the equipment may go out of service and require repair either through the fault of the user or through no fault of the user.

Possible causes of a malfunction of the Baksi gas boiler

The efficiency of the equipment may decrease due to a sharp drop in pressure in the system to 0.8 atm. This can happen due to a coolant leak. It will be possible to avoid this trouble if the pressure is checked at regular intervals, a pressure of 1.5 atm is considered normal.
The equipment may not turn on and start working due to a failure of the draft sensor, which occurs due to the freezing of the pipe through which the air is taken. You can fix the problem by lengthening the pipe by about 20 cm.
As a result of condensate ingress or due to wear, the pressure switch may stick, if the problem is not solved in a timely manner, the flame modulator may fail. For repairs, you will need to buy special spare parts for Baxi gas boilers and call a master who will perform the necessary repairs.
As a result of frequent power surges or a brief power outage, the stabilizer may burn out, causing the device to stop working. To fix the breakdown, you will need to buy a new stabilizer and replace it.
Also, malfunctions of the Baxi gas boiler can be caused due to the shutdown of the gearbox, which can occur as a result of a pressure surge.

There are other malfunctions that may occur during operation. In order to protect yourself as much as possible from an unexpected breakdown of the device during the heating season, it is recommended that the unit be serviced at least twice a year.

Experts advise any gas equipment, for example, a gas wall-mounted double-circuit turbocharged boiler Baxi, check for quality of performance before and after the heating season. With such a responsible approach, the equipment is guaranteed to serve properly, and most importantly, reliably.

What to do if there is a sudden power outage?

Many, in order to protect themselves and their expensive equipment, install generators. Of course, this is a good way out. But there is a much simpler and less expensive solution to the problem.

All that is required is to install a five percent thyristor stabilizer Calm 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. Batteries are connected in series. As a result, we get an additional energy reserve of 150A/h.

Note that when the fan, circulation pump and boiler are running on full power the battery charge is enough for about 11-12 hours of operation, which is quite enough for the emergency to be resolved.

If earlier reliability was valued above all in heating equipment, today they are also expected to be able to work in automatic mode.

The English holding Baxi Group, a well-known manufacturer of gas boilers, takes these requirements into account: the units produced by it thanks to high quality are in good demand.

Our article will help to evaluate their merits, the topic of which is the Baksi 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.
