Gas boilers Ferroli (Ferroli): review, operating experience of wall-mounted and floor-mounted, single-circuit and double-circuit models, their technical characteristics, owner reviews and prices

The boiler is the basis of an autonomous heating system. The future efficiency of heating and the comfort of residents largely depends on the correct choice of unit. Among the samples presented on the Russian market is a Ferroli boiler made in Italy. This brand is one of the most recommended by gas services.

Specifications

In order to choose the most optimal option for a heating device manufactured by Ferroli, a number of parameters should be taken into account:

1. Location - there are both wall-mounted and floor-mounted units. The first are intended for autonomous heating of an apartment or private house. The latter are characterized by high productivity and are installed in large rooms.
2. The number of circuits, a mounted Ferroli double-circuit gas boiler and a floor-standing analogue are used for simultaneous heating of the coolant and hot water. Units with one circuit are connected only to the heating system. As an exception, we can note models with a built-in or separately installed indirect heating boiler.

3. Principle of operation - boilers that include an atmospheric burner are distinguished by a simple operation scheme and unpretentious operation, which explains their low price. Condensation-type devices with a closed combustion chamber have a forced supply of air masses. As a result, productivity increases and gas consumption decreases. In order to ensure the functioning of devices with a closed combustion chamber, electrical energy is required.
4. Heat exchanger - units made of steel are characterized by high performance and heat transfer. That is why they are often installed in industrial premises. Boilers with a cast iron heat exchanger have much lower efficiency, but they will last longer.

Condensing units are connected to a horizontal coaxial chimney. Models with closed fireboxes must be connected to the home's energy saving system. By means of a fan, air is drawn in and combustion products are removed.

Advantages of Ferroli gas boilers

As distinctive features of the units produced by the manufacturer Ferroli, first of all, it should be noted their reliability, innovative technological developments, as well as absolute adaptability to Russian conditions.

Condensing gas boiler Ferroli ECONCEPT tech 25 A

Each model includes a digital microprocessor control system. In addition, automatic adjustment of permanent flame modulation is provided. The surface of the combustion chamber and heat exchanger is coated with a special compound that protects against corrosion. Its key element is aluminum. The burner has a steel head. The inside of the chamber is insulated using a special material that is environmentally friendly and absolutely safe.

Another feature of boilers of this brand is the presence of a frost protection system and an anti-lock pumping system for hot water supply and heating.

Boilers can operate on both natural gas and liquefied gas. The devices are also very easy to maintain - all elements are placed in such a way that they are easily accessible. If necessary, you can create remote control of their operation - to do this, you just need to connect the control panel.

Advantages and disadvantages

The advantages of Ferroli double-circuit boilers should be considered:

• High quality parts, elements and assemblies manufactured using modern technologies.
• Full functionality of boilers that allows you to heat rooms and provide them with hot water.
• Economical, relatively low gas consumption.
• Stability, stable operating mode.
• Availability of several types of design and functionality of units.
• Wide choice of power.
• Ease of Management.
• Availability of a self-diagnosis system.
• Compact, small size.
• Attractive appearance of the units.

The disadvantages of Ferroli double-circuit boilers are:

• Energy dependence. The need to use a voltage stabilizer and correctly connect the phase electrode. Mandatory grounding.
• Excessively high sensitivity of the electronics, often leading to failure of the expensive control board.
• A combined (bithermal) heat exchanger installed on some models requires the use of softening water filters; replacing it costs almost half the cost of the boiler.

Most of the shortcomings are not an exclusive feature of Ferroli double-circuit boilers and apply equally to all similar models from any manufacturer.

Although this does not reduce their negative value, such shortcomings should be treated as design costs.

IMPORTANT! You can avoid harmful consequences by installing a voltage stabilizer and a softening water filter. This must be done from the first days of operation of the boiler. As a result, breakdowns and failure of the electronics and heat exchanger can be eliminated.

Condensing wall-mounted gas boilers Ferroli

The high quality of Ferroli heating units is especially noticeable in condensing boilers, the performance of which is very high, the efficiency reaches 100%. The operating principle is based on the use of thermal energy of steam, which is formed as a result of the combustion of blue fuel. The temperature of the flue gases is used to obtain additional thermal energy, which in conventional models flows into the chimney.

Distinctive features of condensing double-circuit and single-circuit Ferroli units in wall-mounted versions are as follows:

1. Gas consumption is reduced to a minimum. The design of the device has a modulation burner. Automation independently regulates the gas supply based on the specified temperature conditions and seasons. More information about gas boiler automation in this article
2. Thanks to the control system, you can choose the intensity with which the house will warm up depending on the time of day for several days in advance. Some models have special outlets for connecting underfloor heating. Automation heats the coolant simultaneously in both heating circuits.
3. Wall-mounted gas-powered units from the Italian manufacturer Ferroli are completely dependent on electrical energy. With frequent voltage drops, the microprocessor board quickly breaks down. If the voltage drops, the heating is turned off and the station must be restarted. This phenomenon is a significant disadvantage of Ferroli boilers; it is because of it that boiler ratings fall.

The sensitive burner in condensing-type boilers can also operate at low gas pressure. The coolant can be water or antifreeze.

Owner reviews of Ferroli gas boilers: advantages and disadvantages

Wall-mounted units with atmospheric burner

Atmospheric boilers are traditional devices that have an open combustion chamber and a burner, to which air is supplied through natural circulation. Air masses are taken from the room, which serves the needs of the boiler room.

The advantage of wall-mounted atmospheric gas boilers is their simple and convenient design. As a minus, it should be noted the high gas consumption and low productivity. There is nothing complicated in installing wall-mounted boilers classified as atmospheric.

The package includes important elements that affect the performance of the system as a whole. These are an expansion tank, a circulation pump, a gas valve and a burner. Electric or piezo ignition is provided. Piezo ignition is considered a more economical option, since the pilot burner is activated only when the flame extinguishes.

Types of Ferroli units

produces a wide range of household and industrial boiler equipment.

Types of units:

• gas (there are traditional and condensing);
• universal (gas/diesel);
• solid fuel;
• electric boilers.

Gas equipment runs on blue fuel. Hybrid devices have the ability to change gas to diesel fuel. Solid fuel units burn wood or coal to produce heat. Electric versions operate on 220 V.

Wall mounted

Mounted models are represented by gas and electric products of low and medium performance. Having light weight and modest dimensions, they can easily be placed on the wall without cluttering up the room.

Most of the units are designed to heat rooms using a coolant plus the preparation of hot water (hot water). The DIVATOP H model is intended for heating only.

Water for hot water supply is heated using a flow-through method. In DIVATOP 60, the liquid is heated indirectly in a stainless steel boiler. The remaining boilers have two types of heat exchangers installed: plate type or three series-connected pipes of larger diameter, in which coils of thin pipes are placed.

The liquid in the heating circuit heats the copper heat exchanger. It is allowed to use water with a hardness of no higher than 25° Fr (1°F = 10 ɩɩɦ CaCO3), antifreeze, inhibitors and additives as a coolant. Of the non-freezing liquids, only those designed specifically for heating systems can be used.

Based on the type of combustion chambers, there are two types of wall-mounted boilers:

• with an open firebox, they are marked in the form of the Latin letter “C”, such modifications require a chimney;
• with closed - marked with the letter “F”, combustion products are removed using a turbine.

The combustion chambers in Ferroli boilers are made of steel, with an aluminum-based anti-corrosion coating applied on top. Almost all models have an injection burner with stainless steel heads. The flame is ignited without the help of an igniter (there is no pilot burner) using an electric spark.

A special sensor monitors the correct operation of the device; in case of failure, it shuts off the gas supply. Two-position burners are controlled by a microprocessor.

Each wall-mounted boiler has:

• a system that prevents pump blocking;
• anti-freeze system (the burner turns on when the coolant temperature drops below 5 oC);
• control of the removal of combustion products; if the smoke content is high, the burner function is blocked;
• built-in automatic bypass that protects against sudden changes in fluid pressure;
• self-diagnosis;
• It is possible to reconfigure the burner for liquefied gas (performed by service center employees).

The main difference between boilers is the control board: an LCD screen or LEDs can be installed, and there are different ways to change parameters: switches or buttons.

Floor-standing

More powerful units are installed on the floor. It is necessary to allocate a separate place for them, leaving intervals for servicing.

Only four models belonging to this category and operating only on gas are produced:

• PEGASUS D;
• PEGASUS 67–107 2S;
• PEGASUS F3 N 2S;
• PEGASUS DK 130.

All of them are equipped with an open combustion chamber, work with conventional or coaxial chimneys of natural draft, ignition is electronic, the heat exchanger is made of cast iron, sectional, injection burner with stainless steel heads.

Heat exchangers are made of special thermoplastic cast iron, then subjected to tests: peak loads at high water pressure. Service functions include self-testing and frost protection.

Official website: where to view all models and operating instructions

A snapshot of the official Ferroli website in Russia.
In Russia, the official website of the manufacturer is located at https://service.ferroli.ru/

By going to the section “Equipment” → “Ferroli boilers” you can see all available models and their descriptions. For each model, in the “Documentation” tab, electronic copies of complete operating, installation and configuration instructions are attached. The manuals for each model describe the characteristics, installation diagram, algorithm for switching on and adjusting the operation, maintenance features, and contain clear schematic images.

Device

Ferroli double-circuit boilers are designed based on the most efficient designs used in the global heating industry. The main elements are the gas burner, which is located in close proximity to the heat exchanger.

The hot coolant passes into the secondary heat exchanger, where it transfers some heat to prepare hot water.

IMPORTANT! In models with a bithermal heat exchanger, both processes occur simultaneously.

At the exit from the secondary heat exchanger, the heating agent enters a three-way valve, where the hot and colder return flows are mixed in the required proportion to obtain the desired temperature, after which the liquid is sent to the heating circuit.

All processes are controlled by an electronic control board equipped with an extensive network of sensors.

They form the core of the self-diagnosis system, which constantly monitors the condition of the boiler components.

Basic faults and main error codes

All malfunctions of Ferroli double-circuit boilers are immediately detected by the self-diagnosis system and displayed on the display as an error code.

The most common ones are:

The boiler does not start (the burner does not turn on)

Problems with starting a boiler occur most often, since there are many reasons for such a situation.

Among them may be:

• The gas supply valve is closed.
• Gas valve problems.
• The burner nozzles are clogged with soot.
• The control board has failed.
• The boiler is blocked due to a problem with a component.

Most possible causes are detected by the self-diagnosis system and display the corresponding code.

However, some possible reasons - failure of the gas supply system, a closed valve and other mechanical obstacles may not be noticed by the system, so you should independently verify that it is ready for operation . In addition, it is necessary to take into account the phase dependence of the boiler and the need for grounding.

Sometimes, after connections have been made, the wires on the panel are mixed up.

IMPORTANT!

If the phase is connected to the wrong electrode, the boiler will not start. It is also extremely undesirable to have an electrical potential between the working zero and the ground, which causes error A02 to appear.

Price comparison for Ferroli boilers

To make it clearer, the average market prices at which you can purchase a Ferroli gas boiler are given in the form of a table. Let’s immediately make a reservation that all prices are average, and specific figures largely depend on the type of model.

How do Ferroli boilers differ from their competitors?

The main difference between Ferolli gas boilers and units of other brands specializing in the production of gas equipment is that there is the above-mentioned microprocessor control system that regulates the flame level in the devices. The company's specialists created (and immediately patented, of course) a unique small-sized copper heat exchanger, which is coated with an aluminum-based anti-corrosion agent. Typically, such a heat exchanger is found exclusively in Ferroli products.

Domestic buyers are well aware of the products, since it (the company) has been present on the domestic market for over fifteen years. Over the course of all these years, many consumers have appreciated the heating boilers of this brand. They managed to acquire numerous positive reviews left not only by grateful customers, but also by specialists installing or maintaining gas equipment. Excellent external characteristics, ease of use and adjustments - all this is about the Italian Ferroli gas boiler, for which, in fact, consumers value it.

Ferroli company - the history of an Italian enterprise

The company produces 86% of its products for heating apartments and houses.
The Ferroli company, one of the top ten world leaders in the production of heating and air conditioning equipment, appeared in 1955 in the city of San Bonifacio. Gas boilers made by the Ferroli brothers quickly gained popularity among Italians. After 3 years, products began to be ordered for municipal houses in Verona. Following the Italian market, the company's steel and cast iron boilers gained a foothold in other European countries.

In the 90s, an innovative investment program began. New factories are being built and subsidiaries are opening in China. The brand unites several companies under the common Ferroli Group brand. It operates in 5 production areas, but 86% of its products are heating equipment.

In this video you will learn the advantages and disadvantages of a Ferroli double-circuit gas boiler:

Wall mounted

Fortuna

The most common dual-circuit model. It has extremely high technical characteristics, efficiency, depending on power, is in the range of 92.4-93.1%, and the maximum gas consumption of the most common version with a power of 24 kW is 2.72 m3/hour. The primary heat exchanger is made of more heat-conducting and corrosion-resistant copper, the secondary (for hot water supply) is made of stainless steel. The boiler implements the previously mentioned secondary heat exchanger preheating system, which significantly reduces the delay in the supply of hot water.

Available in 10, 13, 16, 18, 20, 24, 32 and 40 kW versions. Mostly in demand are modifications with a closed combustion chamber (F), but there are also cheaper and slightly less productive modifications with an open combustion chamber (C). There are also single-circuit models - Fortuna H, but their cost is only 5-10% lower. The production of Fortuna models is now carried out in China, and not in Italy.
