Autonomous heating and hot water supply is a convenient solution for apartments and private houses. To organize it, first of all, you need to choose a boiler. If the housing is connected to a centralized gas supply system, gas equipment will be the best option. It remains only to decide on the manufacturer and model. So, let's talk about how to choose a Baxi boiler, what characteristics to consider when buying it and which 6 boilers from this manufacturer are worthy of the title of the best.

The main criteria for choosing a gas boiler
When choosing a gas heating boiler, you should pay attention to a number of characteristics:
- Boiler type;
- Thermal power of the equipment;
- Efficiency level;
- Type of instalation;
- Combustion chamber design;
- Equipment energy independence;
- Heat exchanger material;
- Consumable gas volume;
Boiler type
Heating boilers can be single and double-circuit. In the first case, the equipment is designed only to provide heating. The double-circuit boiler also provides hot water supply. An alternative to a double-circuit boiler is to connect an indirect heating boiler with a storage tank to a single-circuit equipment.
Thermal power
This indicator is calculated based on the area of housing. For an accurate calculation, it is necessary to take into account the volume of the premises, the climate of the region, the thickness and level of thermal insulation of the walls, the size and quality of the windows. But in a simplified form, the following formula is used: for every 10 "squares" of area, 1 kW of thermal power will be required. He adds 20-30% to the resulting number, because if the boiler operates at 100% of its capacity, it will quickly fail. If the equipment is also used for DHW, an additional calculation is made for this system.
Boiler efficiency
The boiler efficiency depends on its type. The higher this indicator, the more energy efficient the equipment. Modern condensing boilers have an efficiency level of 110%. However, the higher this indicator, the more expensive the model is.
type of instalation
The boilers are available in wall and floor versions. Wall-mounted models usually have a lower heat output and are compact in size. If there is enough equipment with an indicator of up to 30 kW, the installation of a wall model is permissible, it can be mounted in a non-residential area (kitchen, corridor). Boilers up to 60 kW are most often floor-standing, however, they can also be installed in public premises. If the power indicator is up to 150 kW, the equipment should be in a separate room on any floor. If the unit differs in power above this level, it must be installed strictly on the first floor. or in the basement in a specially designed room with a separate exit to the street.
Combustion chamber design
The boiler heats the water with fire, which requires oxygen to maintain. The combustion chamber can be of two types: open and closed. In the first case, oxygen is taken directly from the room where the equipment is located. In units with a closed combustion chamber, air is blown using a ventilation pipe or coaxial chimney.
For installation in a city apartment, it is worth giving preference to units with a coaxial chimney and an oxygen blower. Equipment with an open burner can be installed in a separate boiler room or annex; additional care must be taken for ventilation in this room.
Equipment volatility
Boilers with a closed combustion chamber are characterized by increased efficiency, however, they require connection to the power supply network. If there is no electricity, the equipment will not work. The same applies to models with automatic electric ignition. If electricity from time to time disappears, it is worth giving preference to open-type boilers with a piezoelectric element.
Heat exchanger material
The material used to manufacture the heat exchanger largely determines the service life of the equipment. They are made from cast iron, steel and copper. The cast iron version is considered the most durable, but such a heat exchanger will weigh decently, in addition, if the operating rules are not followed, it may burst. Steel heat exchangers are cheaper and lighter, but not resistant to corrosion. Copper heat exchangers are the most expensive, but they have high performance characteristics, this material is not afraid of corrosion, has good heat transfer, and is lightweight.
Consumable gas volume
Gas consumption depends on the type of equipment, its efficiency, activity of operation. The presence of automation allows you to significantly reduce the level of consumption.
When choosing a boiler, you should also pay attention to the manufacturer. Equipment of the Italian brand Baxi is characterized by high quality combined with productivity.

FAQ
Why can the boiler hum?
The boiler may hum for one of the following reasons:
- High oxygen content in the heat-transfer water;
- Reduced level of gas pressure;
- Sediment accumulated on parts;
- Fan problems.
Why may the batteries not heat up?
Sometimes, when the boiler is running, the batteries remain cold. The most common cause of this is a pump breakdown or a clogged filter.
