Which Baxi gas boiler to choose for a private home?

Like all gas boilers, the brand’s products are available in different installation options, with one or two circuits and different capacities.

When choosing a unit, you should pay attention to the different series:

• Slim – a series of floor structures with a cast iron heat exchanger, available in various power variations;
• Main - a basic wall-mounted line with a bithermal heat exchanger - the heating circuit and hot water supply go through one heat exchanger, but the water does not mix with each other;
• Eco - are distinguished by the presence of a secondary heat exchanger for the DHW circuit, made of stainless steel, due to which the load is reduced and the service life of the structure is increased. The models also have small dimensions and the latest electronic boards;
• Nuvola are dual-circuit models from the “always available hot water” category. They differ in the speed of heating water in the hot water system;
• Luna is a heating equipment with a removable digital panel.

What characteristics should you pay attention to when choosing a heating boiler?

Keep in mind! Important parameters for boilers are:

• type of unit - there are single-circuit and double-circuit;
• thermal power - calculated depending on the square footage of the heated room;
• combustion chamber design - open or closed;
• energy independence - with regular power outages, this characteristic is important;
• heat exchanger material - directly affects the service life of the equipment.

Types of wall-mounted boilers "Baksi"

Based on the name, it becomes clear that these units are mounted on the wall. There are no strict requirements for the equipment installation process. The boilers are easy to operate and have a large power reserve. Available in several types.

Condensation

A certain part of the generated energy from such boilers is lost along with water vapor. But here you need to take into account the fact that the formed steam condenses. For this process to start, the combustion products must be cooled to a temperature of + 55 °C. This function is performed by the water inside the boiler. It cools the combustion products and then enters the system. For condensing boilers, there are certain requirements for the amount of temperature heating of the coolant.

Compared to traditional units, condensing units allow savings of approximately 11%. The products are not only economical, but also environmentally friendly - they can be installed even in residential premises. They work almost silently.

With one circuit

This type of boiler heats only the water that circulates through the heating system. If desired, the unit can also be connected to DHW, but this will require an indirect heating boiler.

When purchasing such a boiler, you need to take into account the volume of the chamber, based on the number of people living in the house. Units from Baksi with one circuit have a power rating from 14 to 31 kW, which is quite enough to efficiently warm up a country house with an area of ​​no more than 400 m2.

With two circuits

Double-circuit installations are in demand if you need to prepare hot water in a short time. Heating the liquid does not affect the operation of the heating system in any way. The key feature of boilers with two circuits is the presence of two heat exchangers. One is copper, which transfers heat from the unit to the radiator. The second prepares domestic hot water and is created from plates.

The heat exchanger that heats the water is a secondary element. Water is supplied to it as needed. Models with different types of heat exchange elements are produced.

Technical faults and error codes

All failures or breakdowns of boilers are immediately diagnosed by a system of sensors that display an alert in the form of a digital code with the letter “E” (error).

The most common mistakes and owner actions:

• E01 . Keep the burner off. Possible reasons are lack of gas (check the valve), burner nozzles are clogged with soot, problems with the sensor itself.
• E02 . Thermostat overheating. The problem occurs either when the water moves too slowly, or when the heat exchanger is contaminated from the inside with lime deposits.
• E03 . Fan stop. Check it for functionality and replace it if necessary.
• E05 . Failure or short circuit of the air temperature sensor.
• E06 . Failure or short circuit of the DHW temperature sensor.
• E10 . Reduced coolant pressure. The most likely cause is a leak in the heating circuit. This most often occurs when using heated floors, since external radiators signal themselves by the appearance of puddles or streams of hot water.
• E25-26 . Blockage or failure of the circulation pump, failure of the corresponding sensor.
• E35 . False signal about the presence of flame. There may be water on the board, breakdown of the sensor on the case, etc.
• E96 . The power supply voltage is too low.

The full list of errors is much more extensive, so it is recommended to have the user manual included with the boilers at hand. There is no point in learning these codes by heart; it’s easier to look at the list at the right time.

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.

Gas boilersSLIM

This series of heat generators is equipped with two types of combustion chambers:

• closed – 5 models are marked “Fi” and “FiN”;
• open - 10 models are marked “i” and “iN”.

The closed type of chamber in floor-standing boilers is quite rare. But it is precisely these models that will become a real boon for those who, for one reason or another, cannot make a standard chimney. The closed chamber also allows you to install gas equipment in the hallway or kitchen.

An open chamber has nothing in common with contemplating a flame in a firebox. Its name refers to the drawing in of air to form an air-combustible mixture from the room in which the boiler is located. Combustion waste is removed here through natural draft that occurs in a vertically installed chimney.

SLIM boilers are produced:

• single- and double-circuit – at the beginning of the model designation there is the number 1 or 2, respectively;
• with high speed pump and built-in tank, complete with or without hydraulic accessories.

Built-in boilers with a capacity of 50 and 60 liters are made of stainless steel. For the BAXI gas floor-standing boiler , which goes on sale without a tank and pump, the buyer is given the opportunity to flexibly select components. It depends, first of all, on the individual requirements and financial capabilities of the client. Free-standing boilers are available in volumes of 80 and 120 liters in a stylistic design similar to a boiler.

TMBAXI gas boilers are able to operate at reduced gas pressure, which is important in case of unstable situations.

A double-circuit boiler ensures the functional operation of the heating system and provides consumers with the opportunity to use hot water in the absence of a centralized supply. It is equipped with anti-legionella antibacterial protection, which activates once every seven days. At this moment, the contents of the built-in boiler are heated to a temperature exceeding 60 degrees Celsius.

SLIM has the ability to connect to a “warm floor” system due to the presence of two temperature modes. In this case, the equipment is switched to “softer” ranges - from “30-85 degrees” to “30-45 degrees”.

Technical characteristics of boilers of this series:

• power – 15…62 kW;
• heated area – 140...620m2;
• Efficiency – 87.6…90.3%;
• weight – 177…229kg;
• height – 850mm;
• width – 350 and 650mm;
• depth – 520...875mm;
• the number of cast iron sections is from 3 to 9.

The SLIM model means a BAKSI gas boiler, the price of which depends on the type of firebox (open, closed), the number of circuits, and the presence of a pump with a water tank. The recommended cost of the equipment is 1258-2850 euros.

Gas boilers are equipped with electronic components:

• continuous but flexible ionization flame controller;
• ignition, maintaining smooth ignition;
• modulation of fuel consumption.

Flexible, rather than stepwise, flame control helps to save gas. Such modulation actually extends the life of the burner and the boiler itself. When pressure drops in the gas pipeline, the fuel supply and flame intensity are automatically regulated. BAXI gas heat generators can operate on both main and liquefied gas, but switching to a new mode requires reconfiguring the equipment.

Among other things, the boilers are equipped with a number of monitoring, regulating and safety devices. These include:

• timers;
• thermostats – mechanical or programmable;
• pneumatic relay;
• sensors, including traction and street temperature;
• valves;
• self-diagnosis systems;
• pump blocker;
• weather-sensitive automation – provides real savings in fuel resources without human intervention;
• Antifreeze protection – triggered when the water temperature drops to five degrees Celsius. The automation turns on the burner, which turns off only after the coolant reaches a temperature of at least 30 degrees upon entering the boiler.

Remote controls equipped with climate controls are available as an additional accessory. When installing mini-boiler houses, heat generators can be combined into cascade systems. A special device allows you to connect up to four boilers, ensuring uniform loading of the equipment. Consumers evaluate SLIM floor heat generators as highly reliable, efficient and economical equipment.

SLIM series boilers are recommended for home use.

Letters and numbers for the boiler

The marking of SLIM boilers consists not only of numbers that are also present on other BAXI floor-standing gas generators. Let us recall that the first of them indicates the number of circuits, and the next two indicate a rounded power indicator. The letters indicate the presence or absence of certain elements in the equipment configuration:

• i – there is electric ignition;
• N – no built-in tank and circulation pump;
• F – the boiler is equipped with a closed combustion chamber.

Once explained, the markings become extremely clear. Seeing, for example, the designation SLIM 1.230FiN, you can immediately understand that this is a single-circuit floor-standing boiler that runs on gas. Its maximum thermal power is about 23 kW. The equipment set does not include an expansion tank or a pump, but there is electric ignition and a closed combustion chamber.

BAXI LUNA-3 series

Power: 24, 25, 28, 31 kW.

High-performance boilers provide maximum comfort under user control. An advanced electronic board, self-diagnosis and the possibility of weekly programming guarantee high reliability of the boiler operation, as well as ease of use and maintenance.

LUNA-3 boilers are equipped with a wide liquid crystal display, which displays all information about the operation of the unit.

conclusions

Baxi is a popular manufacturer of heating boilers characterized by a long service life, high quality and performance.

When choosing a specific model, you should pay attention to the following characteristics:

• number of circuits - if you need to solve a problem with hot water supply, it is better to go with a dual-circuit model;
• thermal power - the higher this indicator, the larger the room the device can heat;
• type of installation - floor installation is much simpler to implement, but such units are much larger;
• energy independence - this parameter is important for those who periodically experience power outages.

A little history

The largest European holding BAXI Group arose in England 150 years ago - in 1866. Today, he controls more than three dozen specialized companies located in Western European countries:

• England;
• France;
• Germany;
• Italy;
• Spain;
• Ireland;
• Denmark.

Each of the enterprises belongs to the production sector associated with heating equipment, but, nevertheless, there is some division. Some factories specialize in boiler equipment and water heaters, others in components and accessories, including automation and radiators, others in systems related to solar energy, and still others in compact heat and power generators. Moreover, the combined enterprises include a unit engaged exclusively in the development of advanced technologies and their subsequent implementation in the production cycle.

Russian consumers are familiar with the Italian branch of BAXI GROUP through the BAXI SPA trademark. The manufacturing company has been producing heating equipment for more than half a century, including BAXI gas heating boilers, although the factory was initially focused on the production of radiators and enamel cookware, and then bathtubs. The year of foundation of the company is considered to be 1924, the location is Bassano del Grappa, a town in northern Italy, and the founders are the Westen family of Austrian origin. Since 1978, the company has changed its name more than once, joining different but specialized concerns, and since 1999 it received its current name by joining the BAXI GROUP. Today, the Italian factory is the leading enterprise of the holding, producing gas heat generators. BAXI SPA was one of the first to deservedly receive an international quality certificate.

Technical developments introduced into production ensure high quality of BAXI gas boilers, supported by decent service support.

A whole network of branded stores and service centers has been opened in Russia. Here you can familiarize yourself with BAKSI products and documentation, get advice and choose a suitable gas boiler. The equipment is certified according to European and Russian standards, which fully meets the requirements of the modern market.
