Gas boiler "Baksi" - classification of existing models

Not all owners of private houses or cottages have the ability to connect to centralized heating and hot water supply systems.

The reason for this is the distance from the main lines or excessively inflated prices for resources, forcing the problem to be solved in other ways.

The best option is considered to be autonomous heating and hot water systems, implemented by installing your own boiler.

The most economical and efficient of them are gas installations, safe and easy to use.

Let's consider boilers from a well-known manufacturer in Europe - the Baxi company.

Gas boilers from Baxi

The Italian company Baxi has recently become part of the BDR Thermea industrial group.

Baxi is one of the oldest European companies, founded about 100 years ago.

It has been producing heating equipment for about half a century. During this time, extensive production and technological experience has been accumulated, techniques for manufacturing complex components and structural elements have been developed, and the most critical structural elements have been identified.

Gas boilers are one of the company's activities. We produce a wide range of equipment designed to service private homes, office or public premises of various sizes and number of floors.

The main emphasis is on installations designed for heating residential premises according to the principle of “one boiler - one house”. The user has the opportunity to choose an installation that corresponds in power to the size of his home and does not overpay for excess kilowatts.

All installations have a basic set of functions:

• Self-diagnosis (the sensor system provides full control over the condition of the units and elements of the unit).
• Protection against freezing of the system (when the coolant temperature drops to 5°, increased circulation starts).
• Possibility of setting the heating mode and operational control of the temperature of the coolant (HW) if necessary.

Additional functions, such as climate control or advanced methods for regulating the operation of units, can be connected as an expansion of the installation capabilities or purchased outright as a feature of a certain boiler series or model.

The Baksi company has its own iron foundry and metallurgical divisions, which allows it to produce absolutely all equipment components independently and not depend on subcontractors.

How to choose a Baxi gas boiler?

The approximate power of boilers is taken at the rate of 1 kW per 10 m2 of housing area. However, such calculations are very approximate and do not take into account the degree of insulation and heat loss through the windows. In addition, they are not suitable for double-circuit boilers because it is necessary to include power consumption for heating water.

Double-circuit boilers need to be purchased if the house does not have hot water supply at all. In case of seasonal and emergency shutdowns, it is better to purchase a separate water heater (instantaneous or storage).

For hard water, it is recommended to choose the ECO series, where the heat exchanger will not be affected as strongly as in other models.

Kinds

The company produces equipment with various capabilities.

The assortment includes:

• Floor and wall types.
• Single and double circuit.
• Turbocharged and atmospheric (with closed or open burner).
• Cast iron, copper and stainless steel heat exchangers with different capabilities and efficiency.

This abundance of options allows users to choose the optimal installation to suit the needs of a given room.

IMPORTANT!

Baxi boilers are initially manufactured to operate on natural gas, but at any time they can be converted to liquefied gas, for which you need to change the gas burner nozzles.

Types by control method

Baksi boilers are controlled from a panel, in the basic version installed on the unit body.

Later samples received a remote control panel, which can be placed separately from the boiler in a more convenient location. This option is designed for homeowners whose equipment is placed in a separate compartment. You don’t have to go to the installation every time, but make adjustments from a more convenient position.

Finally, there are models with the ability to control from a smartphone . Such units can be contacted from almost anywhere in the world and the necessary settings can be made while being at a considerable distance from home.

This is convenient for people who, due to their occupation, often and suddenly travel to other cities or countries.

They do not need to worry about the state of the home heating system - using an application installed on a smartphone, they can at any time receive a report on the state of the system, the current operating mode, and make the necessary changes.

Baxi boilers advantages and disadvantages

Among the most famous brands, Italian-made boilers rightfully occupy a worthy place. This company produces its heating equipment in many European countries, including our country. This equipment is one of the most technologically advanced and modernized among the lines of gas boilers. First of all, they make it possible to heat not only the room, but can also work as water heaters.

Their product catalog is very diverse, but they all have some common parameters. Gas boilers meet fire and environmental safety requirements and have many advantages:

1. The flame in a gas boiler is smoothly ignited using electricity. Thus, the boiler heats up for a minute at minimum power, then starts working at maximum.
2. The equipment automatically adjusts the flame power to maintain a comfortable temperature in the room. This extends the life of the gas boiler, since the main cause of wear and tear of such equipment - the constant change of on-off cycles - is absent.
3. Gas boilers are also equipped with a post-circulation system, which saves electricity and gas. The thermostat installed in the room turns off the boiler when the required comfortable temperature is reached in the room. Also, if a special temperature sensor was installed on the boiler, it can automatically maintain the temperature, depending on weather conditions and air temperature outside and in the room.
4. Installation of the equipment is considered quite simple. Boilers can be installed on the floor or mounted on the wall. The design itself is considered very reliable and durable, and is light in weight.

The disadvantages of this boiler include:

1. High cost, due to good production quality.

You can see the device in the photo below.

Types and range of Baksi boilers

The range of products is divided into wall-mounted standard and condensing gas heating boilers for premises, and floor-standing gas boilers with a heat exchanger. Wall-mounted and floor-standing boilers can be divided into single-circuit and double-circuit gas boilers of low and medium power; they are used for heating a home and heating water in the private sector. Single-circuit and double-circuit gas boilers Baxi are available with open or closed combustion chambers. Let's take a closer look at each type of boiler.

Wall-mounted gas boilers Baksi

Such Baksi gas boilers are mounted on the wall in any place you like. He does not need a specially designated isolated place. They are easy to use and very powerful, but they must be connected to a chimney; for combustion, air must come from the room (the combustion chamber is open), so additional ventilation in the house cannot be avoided. A boiler with an open combustion chamber implies strict compliance with fire safety and environmental standards.

If you read customer reviews about Baksi gas boilers, you will notice that they confirm the ease of operation of the boilers and their safety. The boilers are equipped with a self-diagnosis system and are able to take into account weather conditions. If the gas pressure drops in the gas pipeline, this will not affect the operation of the stove.

Baksi wall-mounted gas boilers have safety certificates.

The Baxi single-circuit wall-mounted gas boiler is designed for heating a small house. The principle of its operation is simple: the burner that ignites the gas is surrounded by a thermal shell. The heat accumulated in the combustion chamber is distributed through the heat exchanger throughout the entire heating circuit. Heat exchangers are made of copper, cast iron or steel. The Baxi single-circuit gas boiler is not very powerful - from 14 to 31 kW, but this is enough to warm up a house with an area of ​​​​about 400 square meters.

If there is a separate room, then a boiler with an open combustion chamber is suitable. But there are also boilers with closed chambers. If you decide to purchase a Baxi single-circuit wall-mounted gas boiler with a closed combustion chamber, the price for it will be higher than with an open chamber. A boiler with a closed combustion chamber is suitable for installation in living rooms.

The Baxi double-circuit gas boiler serves both as a stove and as a water heater. One circuit heats the water, and the second circuit heats the house. The Baxi double-circuit wall-mounted gas boiler is much more functional; it is equipped with special outlets for the boiler. It can be used to heat water for everyday use, which makes life in the private sector very easy. A heat exchanger is connected to the heating system. The water is heated in a closed cycle, and the heat exchanger simply maintains the desired temperature.

Heat exchanger for heating water, secondary. Cold water enters it as needed, and it works to warm it. If you decide to purchase a Baxi double-circuit gas boiler, the price will pleasantly surprise you. There are two types of heat exchangers on Baksi boilers.

The first is a plate heat exchanger - it consists of a long bent steel tube with soldered copper plates. It is protected from overheating by a special coating. The second is a biometric heat exchanger - 2 tubes of different diameters inserted into each other. The upper one carries water to the heating system, and the smaller tube contains water for domestic needs. A turbocharged boiler with two circuits with accelerated internal processes - it works as a stove and a water heater.

The Baxi wall-mounted condensing gas boiler operates on the energy generated by the conversion of steam into liquid. The energy released during this process increases the energy volume of the boiler several times. Customer reviews explain the great demand for the Baxi gas boiler by the fact that it is almost perfect. The system installed on it automatically adjusts to weather conditions. The temperature of the radiators is (30–85° C), and for a warm water floor (30–45° C).

Errors and interruptions in operation are also independently diagnosed by the system. The liquid crystal display displays all the necessary information. The heat exchanger is protected by an anti-corrosion coating. Flame modulation saves gas, increasing energy efficiency. It works without interruption even in cold weather and when the pressure in the lines drops to 5 Mbar. The boiler runs on natural and liquefied gas. The burners will last a long time, as they are made of durable stainless steel. Cold water is filtered when entering.

Gas floor-standing boilers "Baksi"

BAXI floor-standing gas boilers can also independently diagnose faults, monitor operating readings and adjust them if the pressure in the line fluctuates. Absolutely autonomous, work without outside help.

The supply of gas to the burner is also automatically stopped if something goes wrong, a failure or malfunction.

Floor-standing boilers are produced taking into account the fact that they will be used in various rooms. It is possible to analyze all the parameters and buy a Baxi gas boiler that is optimally selected for a cottage, home or commercial premises. Engineers will install the equipment and make the necessary adjustments at the owner’s request.

Floor-standing gas boilers "Baksi", like wall-mounted ones, can be single-circuit or double-circuit. If we talk about a gas boiler, single-circuit, BAXI, then you need to remember that it is only capable of heating the house, and a double-circuit one also heats water. The Baxi Slim gas boiler is compact and does not depend on electricity. Made of cast iron, equipped with automatic shut-off gas if a malfunction or breakdown occurs. The burner is atmospheric. Boilers have several varieties, differing in power.

A turbocharged gas floor-standing boiler is economical and environmentally friendly; it can easily be installed in isolated rooms. If you use the bathroom or kitchen sink regularly and a lot, it is better to install a double-circuit boiler. If there are two or more bathrooms in the house, then a single-circuit boiler with an additional boiler will be required.

Atmospheric floor-standing boilers with one circuit. According to safety rules, it can be installed where it is possible to connect a chimney, pipe, heating and water supply. If the burner flame goes out, the inlet valve closes. This increases the safety of boiler operation. The atmospheric Vaxi gas heating boiler has two independent circuits, one for heating the house, the other for heating water. Thermal energy is spent to support the resulting heat transfer mode. Cold water flows continuously, so the boiler works to heat it without stopping.

Operating principle

The operation of the boiler is to heat the coolant entering the primary heat exchanger using a circulation pump . At the outlet, the hot heating agent passes through a three-way valve, where it is mixed in a given proportion with a colder return flow, as a result of which the temperature of the coolant acquires the desired value and is sent to the heating system.

Hot water is heated in a secondary indirect heat exchanger . The heat source for it is the hot heating agent, which has not yet entered the three-way valve.

The operation of all components is constantly monitored by a system of sensors that transmit a signal to the control board.

When changing the nominal mode, the display shows an error code related to a specific unit or part of the boiler.

Review of the most popular series

The “line” of products is shown in the table below.

As for radiators, the batteries of this company have the following properties:

• The pressure at which the metal begins to collapse is 34 bar.
• The probable coolant temperature is about 110 degrees. This indicates that it is possible to use not only water, but also any antifreeze in the system.

• Good level of heat transfer. This is likely due to the features of the aluminum alloy from which the radiators are made, and due to the oval shape of the internal channels through which the coolant passes.
• Light weight and, of course, corrosion resistant. Thanks to the first quality, the batteries can be hung on walls with low load-bearing properties, and the second property ensures a long service life.

Note! Radiators of this brand are bimetallic solutions, which indicates that it is very undesirable to drain water from the main line. Due to the fact that oxygen immediately gets inside the channels, and the surface of the elements begins to oxidize.

In principle, we have sorted out the classification of products, now it is worth considering the list of troubles that you may encounter if you operate a Baxi gas heating boiler.

Installation technology

Installing boilers is not difficult. Floor-standing models are installed in a designated area, wall-mounted models are hung on strong walls that are guaranteed to withstand the weight of the units and connecting pipelines.

In this regard, there are certain conditions that prohibit the installation of equipment on plasterboard or plywood partitions and fragile surfaces.

How to set it up correctly

Boiler settings are carried out according to certain rules, detailed in the user manual.

The point of the entire procedure is to set the minimum and maximum gas pressure, determine the parameters of the heating agent and hot water supply. All actions are performed during initial startup or after routine repairs (maintenance).

During boiler operation, current adjustment of the extract air temperature is carried out, which does not affect the general settings of the unit.

IMPORTANT!

Self-configuration of parameters is not recommended, since such actions must be performed by service center employees. Most organizations have a negative attitude towards independent actions and may refuse warranty service.

Price range

The company's products have a wide range of series and models, so the price range is very wide.

The minimum ones are in the range of 25-30 thousand rubles, these are single-circuit installations of relatively low power.

More productive models with a wide range of options are much more expensive - up to 200 thousand rubles. and even higher. Industrial-level installations have a price of over a million rubles, which is explained by their high productivity and ability to serve large areas.

The cost of equipment is significantly affected by logistics - for areas located far from densely populated centers, the price is always slightly higher due to the complexity of delivery.
