Manufacturer information
The Russian representative office of Baxi in Moscow was opened in February 2002.
The Italian brand BAXI SpA has been producing systems for heating and hot water supply for more than 50 years. The manufacturer's line is represented by wall-mounted (standard and condensing), floor-mounted models with cast iron heat exchangers, and storage-type electric boilers.
The company was founded by the Westen family in Austria, but initially it was engaged in the production of tableware. From 1978 to 1984, the brand was part of the Zanussi concern and produced boilers, water heaters, radiators and steel bathtubs. Export of products to countries around the world began in the mid-1980s under the Ocean Idroclima brand.
The manufacturer received its current name in 1999. Currently it is part of two holdings - Baxi Group and BDR Thermea. The international quality certificate ISO 9001 was received in 1993, and environmental friendliness ISO 14001 - in 2001.
The Russian representative office in Moscow was opened in February 2002. The branch is engaged in advertising, marketing, certification of new equipment, consultation and technical support.
Power of Baxi gas boilers
Model Main 5 is a representative of the 5th generation of gas equipment. The electronics of the device are capable of controlling the gas in the exhaust pipe, changing the operating modes of all equipment.
- Representatives of the economy class - Eco Four and ECO Compact are similar to other Baksi models, but have a low price and small sizes.
- The 24-kilowatt member of the Baxi family, Fourtech, is a universal wall-mounted equipment.
Prevention
To prevent breakdowns of the Baksi boiler and thereby extend its service life, this unit should be connected to the electrical network through a stabilizer. Imported electronics are designed for high-quality power supply, and if its parameters deviate significantly from the norm, which we still see quite often, they easily fail.
At certain intervals (after several years of operation), the outside of the heat exchanger must be cleaned of soot. If it is made of stainless steel, you can use a special brush with metal bristles. This tool is not suitable for cleaning a copper heat exchanger, as it can damage it. It is better to use a metal sponge designed for washing dishes.
Gas boiler heat exchanger
The heat exchanger of the DHW circuit needs to be washed from time to time with some descaling agent. The same must be done with the main heat exchanger if ordinary water that has not undergone the desalting procedure is used as a coolant.
The fan must be periodically lubricated, otherwise over time the engine will not be able to rotate it at a sufficient speed. Unscrew the back of the assembly and remove the stator, after which you will need to pour a few drops of machine oil inside.
The chimney, both conventional (for boilers with an open combustion chamber) and coaxial (closed chamber), must be periodically cleaned of soot. The air intake of a coaxial chimney must be kept clean.

Specifications
Malfunctions of the wall-mounted double-circuit gas boiler BAKSI are mainly associated with improper operation. That is why, before purchasing, you should read the passport and instructions, as well as the technical specifications.
The power of boilers has a peculiarity in the form of the need for individual selection for the declared area. Among the models there are several serious options, including those with a power above 60 kW, as well as small boilers of 4 kW, which are designed for a small area.
It is also worth considering that in the characteristics of different models there is a difference in efficiency, which varies from 90% to 110%. The selection of models is carried out according to the stated characteristics.
Important! Models cannot be operated with technical specifications that do not provide for a large amount of work in difficult conditions.
It is worth considering that even models from the same series can differ significantly in the type of operation and characteristics.
Features of Baxi boilers
Thanks to the modulation pump, significant savings occur in gas and electricity. Due to the formation of condensate, the efficiency increases. Special burners allow all equipment to operate smoothly, eliminating various system overloads.
Smart electronics monitor weather conditions, switching the system to the optimal operating mode. The result is cost savings.
The device can be programmed for 7 days. If there is electricity, the gas heater will start automatically.
The Baksi display will promptly report system malfunctions using symbols; all information is stored in memory.
Differences from gas appliances from other manufacturers:
- Availability of a pump with automatically variable speed. This allows you to save energy;
- Two-way brass valve with servo drive;
- Two heat exchangers - copper and stainless steel;
- Electronic water flow meter in the hot water supply system;
- Availability of a filter for water purification;
- The emergency bypass has automatic valves;
- Possibility of connecting additional boilers for hot water.
Types of units by heat exchanger type
The devices are single- and double-circuit. The former are capable of heating water only for the heating system, while the latter can serve as a flow-through gas water heater. Accordingly, they have different heat exchangers installed.
Primary
Such elements are always tubular and look like a monometric device located under the burner. This copper component is responsible for heating the coolant.
Primary elements are installed only in single-circuit boilers, but they are not as common as units with two circuits due to the slight difference in cost.
All Baxi heat exchangers are made from high quality materials - copper and brass. They provide special processing, which makes them reliable and gives them high physical characteristics.
Secondary
They are plate heat exchange surfaces. Energy transfer is carried out through sanitary water. The elements got their name because of their shape - these are stainless steel plates combined with each other.
A secondary heat exchanger is needed for the boiler to work both for heating and for the DHW system (hot water supply).
Bithermal
These copper elements operate on the “pipe-in-pipe” principle. They are designed to heat the coolant for the heating system and hot water supply. They heat water efficiently, but they definitely require that the coolant be of high quality. If the liquid is supplied with many impurities, then thin pipes quickly become clogged, resulting in reduced boiler efficiency.
Choosing a Baxi boiler model
When choosing the right device, you should consider the following aspects:
- The power of the device directly affects the financial costs of purchase and further operation. Insufficient power will lead to uncomfortable room temperatures;
- Is there a need to purchase a boiler with an electrical connection;
- Do you need hot water drainage?
- Installation method: wall or floor;
- What metal is the heat exchanger made of?
- Correspondence between the hood in the house and the combustion chamber of the device.
When choosing a Baksi model, you should listen to the advice of a specialist.
Possible errors and their elimination
Explanation of errors
The manufacturer's instructions will tell you how to start the equipment correctly. It will function properly only if there is protection from voltage fluctuations and a ground line. Special mechanical filters are also required, because... remove solid impurities from water. If installation technologies are violated and there are breakdowns on the line, boilers may produce errors.
Using the self-diagnosis system
All Baxi devices have a self-diagnosis function. Failure data is displayed, the user deciphers the error code according to the instructions and takes action. The following may appear on the monitor:
- Index E and numbers 01 – no ignition. The sensor connection and gas supply are checked. Press R and hold for 2-3 seconds.
- E02 - the thermostat has tripped.
- E03 – normal traction has disappeared.
- E05 – temperature sensor is broken.
- E10 – decrease in pressure, loss of board contacts, breakdown of the relay or pump sensor. The malfunction can only be diagnosed and repaired by a specialist.
- Errors E96, 97 and 98 – failure of the electronic board. It needs to be replaced.
Blocking information may also appear on the display. It occurs when overheating or loss of traction. The user will need to reset the boiler.
Other breakdowns
In addition to errors, equipment failures are observed:
- The burner does not operate at maximum power. The pressure is set incorrectly or the gas valve modulator is broken. To fix the problem, the owner must configure the settings according to the instructions.
- The device turns on, but immediately turns off. The reason is low gas pipeline pressure. It is necessary to make adjustments to 5 mbar.
- The coolant practically does not heat up. The problem can be resolved by testing the gas valve pressure.
- Popping sounds when igniting. There is not enough pressure, the distance from the igniter to the gas supply has changed. To eliminate damage, the gap is adjusted to 4-5 mm.
- Modulation doesn't work. The valve is being replaced.
- Failures in temperature sensor readings. New elements are being installed.
Work on replacing parts and disassembling the boiler should only be carried out by specialists.
The operation of gas boilers from the manufacturer Baksi is possible in apartments, private houses, and industrial areas. Due to the presence of several series and types of equipment, users will not have any difficulties selecting a model.

Possible malfunctions, reviews
According to reviews, for the most part, Baksi have delicate electronics.
Sensitive equipment may not tolerate well or completely break down due to power surges, which occur quite often in the network.
And the more expensive and complex the unit, the more vulnerable it is to poor-quality power supply. Buyers, taught by bitter experience, are strongly advised not to skimp on a UPS and be sure to install it before the first start-up.
It is imperative that the outlet is grounded. By the way, there are opinions that the Luna series has more reliable electronics than the others.
Service centers, of which there are many throughout the country, help deal with breakdowns.
So, Baksi equipment can be selected to suit any capabilities and tastes. The cost of the units themselves is relatively low (especially when compared with solid fuel or pellet boilers). However, delicate electronics and sensors often break down and bad experiences are reflected in many reviews, along with positive ones.
Baxi boilers are widely popular due to their autonomous operation and reliability. Baksi boiler - instructions for use and unit design, read carefully.
