Gas boilers Baksi: reviews and instructions for use

For owners of private houses, the most attractive is 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, equipment, 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 dimensions 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.

Gas boilers Baxi are an excellent combination of energy efficiency, reliability and safety.

These Italian boilers are manufactured according to the latest European standards in the field of efficient use of thermal energy, operational safety and emissions of harmful substances into the atmosphere.

Baksi gas boilers are produced in the widest possible range, which is able to satisfy the needs of any consumer. Baksi wall and floor gas heating boilers are produced in a very wide range. This is a very high quality Italian heating equipment.

Many models of Baxi gas boilers are equipped with separate heat exchangers and a weather-dependent automation system.

The Italian company Baxi dates back to 1966 and has many years of production experience. Today Baxi is one of the largest manufacturers of gas boilers in Europe, and has, for the production of its products, prestigious European prizes and awards.

The priority direction of the company's development is the constant use of innovative technologies and their practical application in production.

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. But 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.

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.

Wall-hung boilers with one circuit

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 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 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 lineup

The Baxi Slim series includes open and closed burner units in its range.

In addition, the list includes single and double circuit samples... Single-circuit ones have a power of 24 and 30 kW (with a closed burner), and from 15 to 62 kW (with an open combustion chamber),

The two-circuit models are available in 24 and 30 kW (with closed burner) and only 24 kW with open burner.

All models have the appropriate designations in the marking, thanks to which you can determine the type of construction:

• The numbers 1 or 2 indicate the number of contours.
• iN - open burner, there are no elements of the hydraulic group - pump, pressure gauge, expansion tank.
• 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 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 quick 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-diagnostics - 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, understandable, 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 parameters are changed.

Also, consumers liked the electrical protection, which is responsible for preventing the formation of scale. There is a thermostat protection in order to avoid excessive heating of water in the heat exchanger chamber. All this significantly increases the term of successful operation of modern equipment.

This model of Baksi gas equipment receives various reviews from professionals. Many leading experts like the fuse in this unit. The boiler is mounted directly in the heating circuit, which is very good. Also, experts from the positive side gave a characteristic of the frost protection system. It functions as it should, and almost never fails. But in some situations the built-in thermostat fails insignificantly. There is also noted a moment as incorrect display of data can cause overheating of the water. But, in this situation, the technical support of the Baksi service center will help, for example, RDTR in UAH.

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.

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..

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.

The presence of electronic modulation of combustion makes it possible to obtain economical fuel consumption, and the heat exchanger covered with an anti-corrosion compound practically excludes equipment failure. In the attached detailed instructions in Russian, you can find information on connection, conditions of use, as well as on the procedure for action in case of possible malfunctions.

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.

Boiler maintenance, ash removal, and other work must be performed once a year.

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 the foreman for repair work.

0 Artem 02/14/2018 13:06 We have a gas boiler Baxi main 24 fi. For 5 years of work, there were no complaints. But in recent months, patience has been lacking. When you take a shower, the pressure in the boiler drops and instead of hot water, cold water flows, the batteries become cold. And so it is stable 1-2 times a week. This has never happened before! What is the reason? How to fix it?

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 breakage or failure of an expensive installation.
