All boilers in a certain price category and with similar characteristics are the same in operation. The models differ only in fuel efficiency, resistance to operating conditions and external adverse factors, and safety. All this is achieved through the use of new and more expensive alloys and materials, and build quality. German gas boilers are considered the reference, but their closest competitors are models from Italian manufacturers, which are often 10-20% cheaper.
In the article we will look at the features, advantages, best models and possible problems of floor- and wall-mounted, single- and double-circuit Italian gas boilers for heating a private home.
Italian double-circuit wall-mounted boilers
Italian heating technology is popular and in high demand.
The reasons for this attitude are:
- Advanced level of design development.
- High quality production and assembly of units.
- Adaptation of boilers prepared for export to the technological conditions of the operating country.
- Constant scientific and technical research, which allows us to quickly introduce improvements into the design, remove defective or weak components and solve other issues.
Many users consider the only drawback to be the relatively high cost of the equipment, although top-level units cannot be cheap by definition.
Most Italian companies have a long history and have accumulated rich production and technological experience, which helps them in creating high-quality and reliable gas boilers.
Reasons for choosing Italian equipment
Although today a wide selection of heating equipment from different manufacturers is offered, Italian boilers occupy a leading position. The Italian double-circuit gas boiler is in particular demand. With its help, you can provide your living space with hot water and heating.
Products from Italy are distinguished not only by high quality, but also by ease of use. They are more expensive than domestic analogues, but the quality is much higher, more durable and reliable. Many Italian manufacturers offer their products, so there are many brands represented.
They all differ in their functions and advantages. It is impossible to answer unequivocally which manufacturer to give preference to when choosing equipment. The company's products are adapted to certain conditions with built-in functionality. Products from some brands are suitable for some conditions, but for others they are completely unsuitable.
The best Italian manufacturers and models: characteristics and prices
Baxi
One of the best and most common Italian gas boilers in Russia for heating a private home. Baksi boiler units have been on the Russian market for more than 15 years and have proven themselves to be the most reliable, efficient and functional for their price. Depending on the model, the nominal service life (declared by the manufacturer) is 12-15 years, which, subject to operating conditions and regular cleaning, is true in more than 90% of cases.
Baxi boilers are among the most affordable of the Italian ones, however, they use modern alloys and technologies. There are also known disadvantages, such as noisy circulation pumps on earlier wall-mounted models, volatility and high power consumption; the automation requires the installation of a voltage stabilizer, since, unlike other Italian analogues, it is still vulnerable to voltage surges.
Wall-mounted Baxi ECO4S 24 F.
The most common model is the Baxi ECO4S 24 F - an Italian double-circuit wall-mounted gas boiler with a closed combustion chamber with a power of 24 kW. The boiler efficiency is very high - 92.9% with a moderate gas consumption of 2.73 cubic meters. m/hour. The boiler is equipped from the factory with a safety valve, an air vent, and protection against pump blocking, overheating or freezing. During operation, no significant deficiencies were found. Cost: 33-36 thousand rubles.
Model LUNA 3 Comfort 1.240 i.
An excellent analogue is the LUNA 3 Comfort 1.240 i model, which features a removable electronic control panel with a built-in room temperature sensor, which allows you to control the boiler from any room in the house. The boiler efficiency is slightly lower - 91.2%, which is still considered an extremely high indicator, gas consumption - 2.78 m3/hour.
Average cost: 39-43 thousand rubles.
Of the floor-standing models, the convection single-circuit BAXI SLIM 1.230 iN with a power of 22.1 kW with an open combustion chamber is popular. The boiler efficiency is optimal - 90.2% with a gas consumption of 2.59 cubic meters. m/hour. It is easy to operate, equipped with a reliable cast-iron heat exchanger, operates extremely quietly and stably, but is vulnerable to voltage surges; it is advisable to install a voltage stabilizer in front of the boiler.
Cost: 53,000-58,000 rub.
Ferroli
The company has specialized in the production of heating equipment since 1958. Models of gas boilers of this brand are distinguished by one of the most compact sizes, high efficiency and safety. Prices for the simplest models start at 25 thousand rubles, which is 10-20% cheaper than Baksi. However, a serious drawback is the low reliability of inexpensive wall-mounted models; perhaps they are the most problematic among all Italian models.
Model Ferroli Fortuna Pro F24.
The most popular and most successful is the Ferroli Fortuna Pro F24 wall-mounted double-circuit boiler with a power of 24 kW and an efficiency of 93.1% with a record flow rate for such power - 1.81 m3/hour. The heat exchanger is made of copper, the model is characterized by quiet, almost silent operation, pre-heating of the DHW circuit is implemented, which significantly reduces the delay in the supply of hot water. Cost: 25-29 thousand rubles.
Of the floor-standing gas boilers, the relatively simple and very reliable Ferroli Pegasus D 23 with a power of 23 kW and an efficiency of 90.9 with a consumption of 2.68 cubic meters has proven itself well. m/hour. It is based on a reliable cast iron heat exchanger and multifunctional safe automation. The only drawback is the inability to regulate the burner power using the controls, which often increases the number of cycles (ignition-extinguishing). Cost: 61,000-69 rub.
Ariston
The manufacturer is distinguished by some of the most heat-efficient wall-mounted gas boilers. Their efficiency is in the range of 93-94%, the build quality, convenient remote control and stylish minimalist design are also impressive. A frequently noted disadvantage is the instantaneous loud ignition in the form of a characteristic pop, while the adjustment of the cycle duration is often limited to 5-10 minutes.
Model Ariston CARES X 24 FF NG.
One of the best is considered to be the double-circuit wall-mounted model CARES X 24 FF NG with a power of 25.8 kW and an efficiency of 93.7% with a consumption of only 2 cubic meters. m/hour. In addition to high efficiency, it is distinguished by reliability, quality of materials used and assembly, functional automation with the ability to plan 7 days in advance. According to the practice of the owners, the boiler heats both the heating circuit and hot water quite quickly and stably.
The only drawback is the loud ignition and noisy operation of the turbine. Cost: 32,000-34,000 rubles.
Lamborghini
The Lamborghini Caloreclima company (from the founder of the famous automobile brand) is one of the leaders in Europe in the production of climate control equipment. The manufacturer's gas boilers are not so popular in Russia due to their extremely high cost, but they are an excellent unique product.
Wall-mounted Fondital Victoria Compact CTFS 24 AF.
Relatively inexpensive and at the same time successful is the wall-mounted dual-circuit Lamborghini FL D 24F with a closed combustion chamber with a power of 25.8 kW. Boiler efficiency is 93% at a flow rate of 2.73 m3/hour. Equipped with a copper heat exchanger with high thermal conductivity, it is characterized by continuous electrically adjustable flame modulation and smooth ignition, which makes its operation almost silent. The boiler also has a high operating pressure in the heating circuit - 3 bar.
Lamborghini Calor boilers are known for their reliability and exceptional quality, but in the event of a malfunction, finding competent specialists and quickly obtaining spare parts can be difficult. Therefore, it is better to choose such rare boilers if you have a house in the Moscow or St. Petersburg regions. Cost: 37-42 thousand rubles.
Immergas
Another manufacturer of wall-mounted gas boilers, characterized by the highest efficiency rates (93-94%). The boilers have an average price for Italian models, intuitive and multifunctional controls.
Mounted Fondital Victoria Compact CTFS 24 AF.
One of the best models is considered to be the Immergas Eolo Star 24 3 with a power of 23.8 kW and an efficiency of 93.4 with a natural gas consumption of 2.7 cubic meters. m/hour. It features extremely fast heating, stability and virtually silent operation. Ignition is smooth, without characteristic pops.
The only drawback, due to the manufacturer’s not-so-great popularity in Russia, is the poorly developed service structure: not all regions have competent specialists, and service visits often take a long time. However, according to practice, the need to call them is extremely rare. Cost: 35,000 rubles.
Fondital
Boilers of this brand are a good alternative to the analogues listed above; they are superior to some models in terms of characteristics, but they also have their drawbacks that do not allow them to be considered the best. The most successful model is the dual-circuit Fondital Victoria Compact CTFS 24 AF with a power of 23.7 kW and an efficiency of 93% with a flow rate of 2.7 cubic meters. m/hour, which is a good average for Italian gas boilers. In addition, high DHW performance and quiet operation are noted.
Model Fondital Victoria Compact CTFS 24 AF.
However, in terms of reliability, Fondital boilers are inferior to their Italian counterparts. A known problem with this model is the incorrect operation of the automation after 3-4 years of use: it turns off the boiler or turns it on outside the heating season, and does not meet the specified heating conditions. The reason is simple clogging of the flame control electrode, which, like many boiler elements, must be cleaned annually.
With more careful maintenance, a high-performance boiler will operate without problems for many years. Cost: 42,000 rub.
One of the most underrated and less common gas boilers on the Russian market, but worthy of attention. Successful models are highly efficient, reliable and silent; after installation practice, there are models that work without problems for 6,7 or even 10 years. However, a noticeable disadvantage is their 8-10% higher cost.
Model Fondital Victoria Compact CTFS 24 AF.
One of the best and most common models is the wall-mounted double-circuit boiler Sime BRAVA ONE 25 BF with a closed combustion chamber with a power of 23.7 kW. The efficiency of the model is 92.9% with a natural gas consumption of 2.7 m3/hour. The boiler has a reliable and efficient copper heat exchanger, stable DHW performance, and operates almost silently, without characteristic pops. But the automation is sensitive to voltage changes and necessarily requires grounding; it is advisable to connect the boiler through a voltage stabilizer. Average price: 33-37 thousand rubles.
The RX 19 CE IONO and RX 19 E floor-standing boilers with heat exchangers made of high-quality eutectic cast iron are also known for their simplicity and durability.
Materials for heat exchanger: which is better
The heat exchanger plays one of the main roles in the design of a gas heating device - the coolant circulates through it. The most common materials used in the production of heat exchangers for gas boilers are copper, cast iron, and steel.
Steel version of the heat exchanger
The cheapest, and as a result, the most popular material for a heat exchanger is steel. Therefore, it is actively used by domestic manufacturers in order to reduce the cost of the final product. Unlike cast iron, it is not brittle.
Compared to cast iron, steel is much lighter, but when compared to copper, it significantly exceeds its weight and makes the boiler structure heavier.
The steel heat exchanger heats up and cools down quickly. In addition to convenience, this leads to negative consequences - “fatigue” of the metal causes damage. The disadvantage of steel is also its susceptibility to corrosion.
During operation, both the internal and external sides of the steel heat exchanger are subject to corrosion. Over time this leads to its destruction
Copper type heat exchanger
The material has many positive properties - corrosion resistance, small volume, low inertia. Due to its compactness and low weight, copper is actively used for the production of lightweight wall-mounted boilers.
Non-corrosion is one of the main qualities for heating equipment intended for heating process water.
The opinion about the fragility of copper heat exchangers has long been refuted by manufacturers of modern heating equipment - in them, the burner power is reduced by 30%, which reduces the thermal effect on the metal and has a good effect on the duration of operation.
Boilers with cast iron heat exchanger
The main quality of cast iron that should be noted is its inertia. The material takes a long time to heat up and cools down for a long time, which increases the efficiency of heat transfer.
Such inertia can be considered both a positive quality and a negative one - in the event of sudden warming outside, the boiler will maintain a high temperature in the heating system for a long time.
A cast iron boiler weighs twice as much as a steel one, so the boiler design is made sectional to make it convenient to deliver, install and repair
Cast iron is subject to dry and wet corrosion. The latter contributes to the appearance of rust, but due to the thick walls, the corrosion process extends over a long time.
The disadvantages of cast iron boilers include the fragility of the material, which manifests itself as a result of improper operation - temperature changes, mechanical damage during transportation and installation.
Immergas
Immergas is one of the leaders in the market of heating devices for public and domestic premises. The company's headquarters have been located in the Italian city of Brescello since 1964. Immergaz boilers are represented in more than 32 countries around the world. The manufacturer is constantly improving its products and expanding its supply boundaries.
The manufacturer has a personal development and research center engaged in the design and manufacture of all types of heating structures. All products comply with the standards of each country where supplies are made.
Construction of the Immergas ZEUS Superior gas boiler
SeriesCharacteristics

Gas boilers require regular maintenance.
In what modes can it operate?
There are two main operating modes of a double-circuit gas boiler:
- Winter mode. This is the full operation of all systems of the unit - heating the coolant, preparing hot water with the specified parameters.
- Summer mode. During the warm season, the heating circuit is switched off, only DHW heating remains active.
The transfer from one mode to another is carried out by the user himself; this is a standard procedure that does not require the intervention of specialists. The owner decides when the heating can be turned off and when it should be started.
At the same time, hot water supply is needed all year round, so the DHW circuit is always running, although if it is no longer needed, water heating can also be turned off.
There is another, protective mode of operation of the gas boiler. It is designed to prevent freezing of the coolant in the system when the temperature drops to a set limit.
In such situations, increased circulation is launched, when the circulation pump begins to drive the heating agent through the system at an increased speed and prevents it from freezing.
In Russian conditions, such a function is very useful and allows you to avoid serious problems.

Operating principle
Combustion of fuel contributes to heating of the coolant in the primary heat exchanger.
The circulation pump ensures the movement of water through the system, constantly supplying new portions of the cooled flow to replace the heated one.
The three-way valve regulates the temperature by mixing a certain amount of cold coolant into the flow with the maximum degree of heating, resulting in the formation of a given temperature in the system.
Fuel combustion is supported and enhanced by the air flow supplied by the turbocharger fan.
All work is constantly monitored by appropriate sensors that transmit signals to the control board, which interacts with the remote control.
Kinds
Wall-mounted double-circuit boilers are the most popular type of heating products.
They are compact, fit well into the interior of any room, and have a full range of functions.
Italian engineers are leaders in the development and design of gas boilers, so the range includes all current types of units:
- Convection. The coolant is heated in the primary heat exchanger using heat from a gas burner.
- Condensation. A relatively new design that heats the coolant in a stepwise mode: first, thermal energy obtained from the condensation of water vapor from the exhaust smoke is used, and then follows conventional heating in the primary heat exchanger. Primary heating is relatively small, but it allows you to reduce the intensity of the main heating, which ensures gas savings and increases the service life of the heat exchanger by softening the operating mode. The efficiency of condensing boilers, declared by manufacturers, is about 107-109%, which cannot be from a physical point of view, but works great as a marketing ploy.
In addition, there are models with different types of combustion chamber:
- Open (atmospheric). They work on the principle of a conventional stove - smoke removal occurs through a common house chimney using natural draft, combustion air is taken directly from the room in which the boiler is installed.
- Closed (turbocharged). Air intake occurs from the outside, and smoke exhaust is provided by a turbofan.
PLEASE NOTE! Atmospheric boilers are a tribute to tradition, which in today's conditions looks like an atavism. Natural cravings are extremely unstable and depend on a host of external factors. Initially, atmospheric boilers were produced in a non-volatile version, but over time they began to install electronics, which made the design incapable of independent operation.
Criterias of choice
A wide variety of gas boilers and other types of heating equipment often confuse buyers. The right choice must be based on certain requirements. Having found out for yourself the purpose of the device, you should then take into account the main parameters:
- Type of fuel;
- power;
- dimensions;
- type of instalation.
According to experts, gas boilers are the most cost-effective and easiest to operate. Not only the heating of the room, but also the costs will depend on the power of the model. There are products that can be hung on the wall in the hallway or in the kitchen. More bulky units will require a separate room. When choosing the type of installation, you should take into account the layout of the home and the weight of the equipment for creating heat supply.

Reviews
Victor Annikov, 56 years old, Kasavyurt
The simplest gas boiler worked in my house for almost 20 years, and it served its purpose well. When the time came to change it, we immediately decided to install a dual-circuit model, since children and grandchildren often come to us on weekends. Due to the fact that we have very little space in our house, even though it is 100 square meters, we decided to install it in its old place - in the kitchen. As a result, we settled on the mounted Italtherm City Plus 24C model. I don’t remember how much it cost us, but since we bought it for the New Year, we got a special offer - they gave us a gas filter and a voltage relay as a gift. The device worked fully for one season, and there are no complaints about it. Even when we went on vacation for a week in winter (the boiler was turned off), after our return, the unit quickly managed to warm up the entire house - literally by the evening it was as warm as if we had never left.
Igor Valetnikov, 45 years old, Novy Urengoy
I installed a Domiproject double-circuit boiler for my parents 3 years ago. I didn’t really trust the domestic manufacturer, since I already had a negative experience, and with the same boilers. My parents are already old, so I chose a model that was as easy to use as possible. Domiproject has continuous flame modulation and frost protection. Since the unit was supposed to hang in the corridor, it was important for me that it have compact dimensions. The model has an electronic “filling”, the operation of which is displayed on the LCD display. Therefore, if any malfunction occurs, parents will easily understand it, and thanks to the decoding in the instructions, they themselves will determine the fault code. This device can even work with solar collectors. Maybe in the future I will improve their house in this sense.
Yulia Vereskova, 39 years old, Nazran
At our house, almost all the equipment is from Ariston, so when we were choosing a boiler for heating and hot water, it somehow happened naturally that we decided to go with the same manufacturer. Since we often have problems with gas pressure, the Ariston boiler is perfectly adapted to this. This year we also connected street sensors to it, thanks to which we no longer have to run to the boiler and regulate its operation. In addition, this also saves gas consumption somewhat, since in winter we do not constantly have frosts. At the time of purchase, the seller told us that several more boilers can be freely connected to this model, that is, if we upset the house, there will be no problems with heating.
Device
The design of Italian boilers is practically no different from the design of all the most popular models. Actually, most manufacturers try to copy the basic ideas and directions followed by Italian engineers.
The main elements of the boiler that provide the main functions are the primary and secondary heat exchangers, as well as the gas burner. The coolant, under the action of the circulation pump, is supplied to the primary heat exchanger and heated to the temperature determined by the set mode.
At the exit from the primary, it immediately enters the secondary heat exchanger, where it gives up a certain amount of thermal energy to prepare hot water, after which it finally enters the heating circuit.
In condensation models, the coolant is first supplied to the condensation chamber, which is the same heat exchanger. There it receives primary heating, after which it moves according to the standard pattern.
It must be taken into account that efficient operation of condensing boilers is only possible in low-temperature systems. If the return coolant flow is warmer than the condensate, then there is no point in such a design.
This limits the use of condensing boilers - the difference between the temperature inside and outside the room should not exceed 20°.
IMPORTANT! Condensing boilers are approximately twice as expensive as conventional convection models, therefore, when purchasing, you should first figure out whether such a design will be effective under the existing conditions.
Features of a double-circuit gas boiler, what is the difference from a single-circuit one
A double-circuit gas boiler is a modified design of a single-circuit unit. Both types are focused primarily on performing a basic function - heating the coolant for the heating system.
DHW supply becomes possible due to the presence of hot coolant (HW); the second circuit is a structural addition to the main composition of components and parts.
The function is implemented using a secondary heat exchanger installed between the output of the primary unit and the three-way valve.
Passing through the primary (main) heat exchanger, the coolant receives an excess amount of thermal energy, which is regulated in a three-way valve by mixing a certain amount of colder return fluid.
This energy is wasted, so installing a secondary heat exchanger does not disrupt the overall operation of the boiler.
The hot coolant gives up excess energy to prepare the hot water supply, and the only change is to adjust the operating mode of the three-way valve.
There are double-circuit boilers with a combined (or bithermic) heat exchanger, which is capable of heating the coolant and hot water at the same time.

- The boiler produces the last few degrees and operates at low power. This reduces the number of starts.
- Noise during operation is reduced due to the heating mode, where the gradual start function operates. This function brings the system to the desired mode in 35-45 seconds.
- The Baxi boiler has a built-in anti-blocking function to protect the three-way valve and pump. The circulation pump operates after the unit stops operating. If the design is with a thermostat, then the duration is three seconds; if without it, then the operation is continuous.
- The unit’s automation is configured in such a way that it itself adjusts the operation of the structure in connection with the temperature outside the window.
- Built-in programming function. Makes it possible to configure the program for On/Off mode and reduced coolant temperature in the heating circuit. You can set the Auto Shut-off program in the hot water supply circuit.
- The unit has two modes: radiator high-temperature, panel low-temperature.
- Function to protect water from bacteria. The work is carried out in conjunction with a storage boiler. The water heats up to seventy degrees and harmful microorganisms in the storage tank disappear.
