Gas boiler Baxi Slim: floor-standing double-circuit device, its device, reviews and price

Owners of private houses are most attracted by their own autonomous heating system.

In any case, it will be more efficient, economical and maintainable.

In the event of a serious accident on the main line of the centralized line, it will take the efforts of many people, technicians, and time.

An autonomous system located within one house can be repaired in a maximum of several hours.

The main task is the correct choice of the main element of the system - a heating boiler capable of performing its tasks in the most efficient way.

Series of gas boilers Baxi Slim

The Italian company Baxi (Baxi) has been producing various heat engineering installations for more than half a century, performing the tasks of heating rooms and preparing water for hot water supply. The range of manufactured units is wide; there are devices for any conditions and specific tasks.

Gas boilers are among the most popular type of devices, since their economy and efficiency are significantly ahead of other designs..

The Baxi Slim series (Baxi Slim) represents a model line of boilers, a feature of which is increased power and wider possibilities in comparison with wall-mounted samples.

Several design options with an open or closed burner, single or double-circuit types of units are offered to the attention of users.

All installations have approximately the same set of functions, a self-diagnosis and protection system.

There is no fundamental difference in the structural relation between them, only the power of the boilers differs, which determines the size of the serviced premises.

Floor standing gas equipment

In the production of baxi floor standing appliances, there are two directions:

Condensing, using both the energy of gas combustion and the power released during the condensation of combustion products;
Single and double-circuit with atmospheric burner.

The SLIM series is distinguished by the use of cast iron heat exchangers, small dimensions and modern design. The latest technical developments allow the automation to detect up to 10 faults in the system, which makes it possible to carry out timely repairs and extend the operating time.

Such devices have become popular due to their ultra-compact dimensions and the following technical characteristics:

providing flame modulation;
the atmospheric burner is made of stainless steel;
durable cast iron heat exchanger;
modern automation;
protection against water freezing.

All baxi ultra-compact boilers are fully adapted to Russian conditions. They are designed for both fairly frosty winters and instability of pressure in gas pipelines and voltage in power grids.

The equipment made in Italy demonstrates English punctuality and reliability in operation, and according to consumer reviews, it is excellent for Russian homes.

Baksi Italian gas boilers today are full-fledged participants in the modern heating equipment market. They have managed to establish themselves as high-tech and safe devices that are perfect for small houses or apartments, and for industrial enterprises.

Features of the

Equipment under this brand is developed, manufactured and sold in Italy, England, Germany, India, China, Finland and Holland. The history of the brand begins in 1866, and today the company is among the leaders in sales of heating equipment in Europe.

BAXI gas equipment and boilers have the following distinctive features and advantages:

Smooth electric ignition.
The flame is modulated continuously.
Post-circulation.
Automatic adjustment depending on the weather.
Self-diagnosis.
Frost protection system.
Work programming.
Interlock protection
Protection against bacteria.

In addition, the manufacturer equips its equipment with energy-efficient WILO SE and GRUNDFOS pumps. Also, gas heating boilers provide for the possibility of changing the type of fuel (from liquefied gas to natural gas and vice versa). Some units can be installed outdoors.

What is the difference between wall-mounted and floor-standing boilers?

There is no fundamental difference in the design of wall-mounted and floor-standing boilers. However, taking into account the difference in installation conditions, you can notice a significant difference in the design requirements.

Hanging the unit on the wall sets certain conditions, requirements for the bearing capacity of the wall, limits the boiler by weight.

A floor sample can be made from stronger and heavier materials, high-quality and massive units can be installed.

Accordingly, this freedom from restrictions allows you to increase the power and productivity of the unit, to increase its efficiency.

Baksi floor-standing boilers are designed to heat a much larger area than wall-mounted installations..

They are capable of heating industrial or public premises with an area of up to 500-600 m2, which wall-mounted boilers cannot.

Baksi gas boilers - user reviews

“… I would like to note that Baxi boilers are not a cheap pleasure. For example, an average device from Baxi will cost at least 25,000 rubles. We are talking about the Baxi Fourtech 240 Fi boiler. It is a wall-mounted model that can run on natural gas and is supplied with two circuits. Hanging on the wall.
As for the power - the maximum boiler power is 24 kW, that is, the Baxi Fourtech 240 Fi model can heat 240 m2 with a ceiling height in the room not higher than 2.7 meters. And now criticism towards Baxi boilers. All Baksi models require annual maintenance. Many sellers position this idea at least very strongly.
In addition, boilers are explosive (according to reviews on the forums), and this is a real phenomenon, especially if you miscalculate the cubic meters of the room. Of course, about the explosion hazard - this statement is not only true for Baksi boilers, but also for other boilers. Also, many complain about noise and spontaneous shutdown ... "

Anatoly Georgievich, Balashikha.

“… To keep warm in my house (second floor 50 m2, and 100 m2 first) I chose the gas heating boiler Baxi Luna-3 Comfort 240Fi. I delivered it more than three years ago, and I am 100% satisfied with the purchase. I chose for a very long time - after going to forums and shops, after viewing reviews and collecting opinions about these boilers from people who have been using this model for a long time.
One thing is clear - indeed, I had to talk a lot with company managers (more than ten) and review many posts on the forums before deciding to buy a Baksi boiler. As mentioned above, I am completely satisfied, the house is warm, and I practically do not look into the boiler - I just wipe it from time to time ... "

Maxim, Dolgoprudny.

“… Our family recently purchased a Baxi Main Four 240Fi boiler. It was suggested to us by friends who have been using this particular model for 5-6 years. No shortcomings have yet been noticed, but what has become much more economical and more comfortable - everyone felt at once. Our house is quite large, and it was quite problematic to heat it with an old coal boiler.
Everyone was just tormented - they had to get up early to light the boiler, they couldn't leave for a long time, and so on. The frozen cast-iron radiators have already been changed once, so they decided to change the heating system to gas heating. Now we really feel free and confident ... "

Oksana, 38 years old, Moscow region.

“… My wife tried to persuade me to buy autonomous heating for a long time, and I resisted to the end, but she won. I was afraid that either the gas would be cut off, or something else would happen - this is how the 90s scared us. But still I made up my mind. First, it was necessary to choose the right boiler model.
After lengthy but informative consultations and visits to all kinds of stores, we chose Baxi 24 F, just like our friends. At first, we were interested in the dimensions of the boiler, but this model had them more than compact, and we stopped doubting further. This model has been working for six years already, and for all the time the problems have not manifested themselves in any way ... "

Osipov Nikolay Petrovich, Podolsk.

The choice of heating technology on the modern market is diverse and multifaceted. When deciding which model will be the most harmonious in a house or apartment, you should definitely pay attention to English equipment. Elegance and severity of forms, combined with attractive characteristics, will certainly interest both the owner of the house and the heating engineer.

The popularity of British heaters with the baxi brand is associated with exceptional reliability and technical innovations in the design of any model on the market. The constant introduction of the latest developments of the corporation's engineers has made it possible to obtain practically perfect gas and diesel boilers, boilers, water heaters.

The technical characteristics of the baxi gas boiler meet the most demanding requirements, while the price makes it possible to purchase a similar device for middle-class customers. The presence of a number of subsidiaries in various countries of the world, for example, Italy and Turkey, helps to reduce the cost of production.

Special attention by the corporation's specialists is paid to reducing energy consumption and the use of alternative fuels. The solar systems developed at the enterprise can operate both autonomously and in tandem with a gas unit, thus significantly reducing gas consumption and reducing operating costs.

Existing types

There are two types of boilers:

Single-circuit... Designed to perform a single function - heating the coolant (or heating water, OM).
Double-circuit... Provide the room with hot water (DHW), in parallel with the heating circuit power supply.

In addition, there are options with an open (atmospheric) or closed (turbocharged) burner, the difference between which lies in the design of the combustion chamber.

The first option is much simpler and cheaper, the second provides for the presence of a fan supplying fresh air to the chamber and providing a predetermined combustion mode.

Most models are provided with a two-stage burner that allows modulation of the flame. This increases the efficiency of the installation, allows you to smoothly change the settings and obtain accurate temperatures in the circuits being serviced.

New model "Baksi Eco Four 1.24"

These boilers "Baksi" have different reviews. Of the shortcomings, consumers note the work of the electric ignition of the device. At the same time, the dimensions of the boiler are average: the height is 730 mm, the width is 400 mm, and the depth is only 299 mm. The total weight of the device is 32 kg. During this time, many appreciated its ability to work at low pressure. The air supply, in turn, is very smooth. Overall, the combustion chamber is well sized and robust.

Additionally, an ionization controller is installed to regulate the combustion flame. For this, special stainless steel dividers are built in. The heat exchanger is made entirely of copper, which delighted the buyers. At the same time, there is an anti-corrosion protection system. The pressure gauge of the device is built-in and works properly. Additionally, these heating boilers "Baksi" have good reviews for the quality of the filters, which are responsible for rough cleaning at the inlet. This model can be connected to solar collectors.

i - open combustion chamber, there is a hydraulic group.
FiN - Closed combustion chamber, no elements of the hydraulic group.
Fi - closed burner, there are hydraulic elements.

IMPORTANT!

Models without a hydraulic group are much cheaper, but they need to install a circulation pump as an additional element, otherwise the coolant will not circulate and the system will not work.

Wall mounted gas heaters

Wall-mounted units are lightweight and compact enough. Domestic customers have become popular series ECO, Luna, NUOVA, which are fully adapted to the peculiarities of Russian conditions. A special board performs diagnostics of the equipment operation and ensures perfect functioning even when the gas pressure drops.

The baxi wall-mounted boilers are distinguished by the presence of a liquid crystal screen, which allows you to monitor the parameters of the device. At the same time, the device operates completely autonomously, does not require intervention and makes it possible to leave the device unattended for a long time.

The system of sensors and thermostats provides a timely response to changes in indoor temperature and outdoor weather. To increase the efficiency of the equipment, a room thermostat is installed, which automatically maintains the set temperature in the room. The efficiency is increased with an optional external sensor.

In the line of wall-mounted units, two directions can be traced in the method of heating water, each of which is equipped with modern equipment that ensures the maximum functionality of the model.

Equipped with a bithermal heat exchanger, they quickly heat up the running water due to the direct heating of the coil. The simplicity of the design ensures ease of maintenance, and if necessary, repairs will be made in one of the many service centers. The reliability of the device is evidenced by the factory guarantee of a five-year trouble-free operation.

Smart automatics will turn on the equipment only when necessary, and flame modulation will help eliminate water temperature drops.

FOUR TECH

This ultra-compact boiler does not require a lot of installation space, and the composite body ensures minimal weight. The main difference between the model is a special block that allows you to regulate the flow of hot water and adjust the temperature of the coolant. The turbine flowmeter will provide complete automation of temperature control.

LUNA

The LUNA model range unites a line of high-performance double-circuit boilers with an LCD screen and, with a low weight, providing a gas consumption of 3.2 m3. This category includes units with remote control, which allows, taking into account the weather forecast, to adjust the automation for the next two weeks, saving energy consumption and correcting possible errors in standard settings.

In this series, there are models that allow outdoor installation and reconfiguration for operation on liquefied gas, as well as providing for the connection of a "warm floor" system.

ECO Four

ECO Four boilers have a record low weight (less than 30 kg) and small dimensions. Models are available in single and double-circuit, equipped with a copper heat exchanger and a convenient informative display. Such devices are easily installed in any room, take up a minimum of space and fit aesthetically into any interior.

They can control the operation of several autonomous circuits.

Each of the lines of equipment also has its own characteristics.

Luna Platinum - wall mounted gas condensing boilers with removable control panel. The power of the units is from 12 kW to 33 kW. In addition to the functions listed above, these boilers have a very wide power modulation range - 1:10, which allows the most efficient use of fuel and stable temperature maintenance.

Condensing boilers Baxi

The hydraulic system has a modulating pump with a built-in automatic air exhaust system for forced circulation of the coolant in the heating system. There is a pressure gauge to control the pressure (on the front of the boiler). It is possible to programmatically set the temperature for each day of the week. The equipment is regularly tested (self-diagnostic function), in the presence of emergencies, the results are displayed on the LCD display, several records of previous operating errors are stored in the memory.

Luna Duo-tec - single-circuit and double-circuit condensing boilers with a power modulation range of 1: 7. The power of the units is from 12 kW to 40 kW. Among the features - an energy-saving circulation pump with automatic air venting from the system, a filter at the cold water inlet, an electronic pressure gauge that turns off the equipment when the gas pressure is below 0.5 bar, a safety valve that turns off the burner when the pressure in the system rises above 3 bar.

Device

The device of the units does not have significant differences from analogues of other manufacturers or generally accepted schemes.

Baksi Slim boilers consist of the following units:

Gas burner open or closed.
Heat exchanger of sectional type made of cast iron.
Circulation pump.
Three-way valve.
Expansion tank.
Turbocharger fan.
Self-diagnosis control board and sensor system.

The operation of the boiler is based on the process of heating the coolant and organizing its circulation. Heating is carried out in a heat exchanger, where the heating agent receives heat energy from gas combustion.

The hot coolant passes through a three-way valve (mixing unit), where a colder return flow is mixed into it in a certain proportion.

It turns out the OM of the required temperature, which is sent to the system. Hot water is supplied to the taps after passing through the heat exchanger.

Its temperature depends on the intensity of parsing, the more the tap is open, the colder it is.

Wall mounted boilers

Wall-mounted gas heating units are still more in demand than floor-standing models. After all, they are most often installed in the kitchen: there are all the communications that are needed for the operation of these devices. Therefore, the design is developed taking into account the installation location: more suitable for kitchens. Wall-mounted gas boilers Baxi are no exception - they are made with truly Italian elegance.

Luna3 ("Moon 3") and Luna3 Comfort) - gas-powered units of the third generation for heating and water heating. In these lines there are boilers with one circuit - only for heating, there are two - in addition to heating, water is also heated for domestic needs. The boilers are produced with a medium power range - 24 kW to 31 kW. For fast heating of water, the heat exchanger installed in Luna boilers is large, there is a brass hydraulics group in them. In models for hot water supply, a flow meter with a turbine is installed. Luna 3 can operate in conjunction with the Baxi solar circuit.

Double-circuit gas boilers "Baksi"

One of the automatic functions that distinguishes Luna 3 from analogs is the programming of heating parameters for a week. Another more common one is self-diagnosis - at regular intervals, key indicators of the system are checked and compared with reference values. The test results are displayed on the LCD. Another distinctive feature is the adjustment of the burner operation and the supply of gas, air according to the weather outside, for which a special sensor installed outside is used. Depending on its readings, the intensity of combustion is selected.

Luna 3 Comfort, with similar functionality, is distinguished by the presence of a special panel: it can be removed from the boiler. It is connected to the equipment with an elastic cable. A contactless version is installed on request. The remote control has a built-in sensor that monitors the air condition in the room, it is possible to set a timer for heating and hot water supply

Main 5 and ECO Compact - units of the fifth generation of small sizes (70 * 40 * 30 cm). A convenient LCD panel is located at the bottom of the casing. The control is easy, straightforward, setting and changing the temperature of the coolant or hot water takes place in a few clicks. These lines use a new principle of control for the presence of a flame, new sensors for the removal of combustion products and the presence of thrust. These innovations make it possible to more accurately adjust the operation of the burner and air supply to the real state of the system. Also, these new measuring devices make it possible to accurately adjust the operation of the equipment in accordance with the state of the system (adjust the combustion to the amount of thrust and the amount of air supplied to the burner unit), which makes the operation of the equipment more stable even when the parameters are changed.

Wall-hung gas boilers baxi Main 5 ("Main 5") and ECO Compact

Main 5 units are available with two circuits, power from 14 kW to 24 kW. Fast heating of water is provided by a bithermal heat exchanger.

Devices of the ECO Compact line are available with one or two water heating circuits, ranging from 14 kW to 24 kW. They have a compact group of hydraulics. At the inlet of the primary stainless steel heat exchanger there is a removable filter, the secondary one for hot water supply is also made of stainless steel, but has a plate shape.

Any boilers of this group are equipped with frost protection, it is possible to connect a sensor that measures the outside temperature with subsequent adjustment of the system to these parameters.

Fourtech (Fortech) and ECO Four ("Eco Fo") wall-hung gas boilers of the third generation, which are developed on the basis of the ECO-3 Compact line. There are both single-circuit and double-circuit installations, with a closed or open combustion chamber. The power of the units is still within the same framework - from 14 kW to 24 kW, the dimensions are small - 700 * 400 * 300 mm. In boilers with hot water supply, a stainless steel plate heat exchanger. All units have built-in frost protection, a hydraulics group with a three-way valve powered by electricity and a cold water inlet filter.

Where is used

Floor-standing boilers of the Baksi Slim series have great possibilities for space heating.

Unlike wall-mounted installations, which are limited in their capabilities, individual floor samples are capable of heating up to 600 m2, which corresponds to the area of an industrial workshop or a fairly large store, public center, etc.

For heating private houses, models of relatively low power are used, corresponding to the size of the house.

They are focused on the supply of hot water and heating, while powerful installations mainly heat the heating medium for the heating circuit of the room..

User's manual

For the operation of Baksi Slim boilers, it is only necessary to create the appropriate conditions - to connect the appropriate communications, ensure an uninterrupted and stable supply of electricity and gas, organize a water supply and connect a heating circuit.

No further action is required from the user, except for the current setting of the desired temperature.

Once a year, boiler maintenance, ash removal and other work must be performed.

To do this, you should invite a specialist from the service center with the skills and experience in servicing such installations.

NOTE!

In the event of failures, errors or other malfunctions, you should immediately stop the boiler and call a foreman for repair work.

Atmospheric floor standing boilers with one circuit

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.

DIY customization

Self-tuning of boilers consists in installing, connecting all the necessary communications and power supply.

Then it is necessary to fill the system with water, for which the make-up valve is opened and a pressure of 0.7-1.5 mbar is formed on the pressure gauge.

After that, the following actions are performed:

The power supply turns on.
The gas valve opens.
By turning the corresponding switch, the "summer" or "winter" mode is switched on.
The temperature of the extract air and hot water supply is set,

After that, the boiler will start working, the burner will ignite and the coolant will circulate.... It is strongly discouraged to make finer settings on your own, since there is a risk of damage or failure of an expensive installation.
