08.03.2020 Accessories

FERROLI was founded by Mr. Dante Ferroli in the Italian city of San Bonifacio in 1955. The products of a small workshop that produced gas boilers were a success with the residents of the city, and already in 1958 the company received the first large order for the supply of 500 boilers for the municipality of the regional center - the city of Verona.

FERROLI products are beginning to gain popularity and are gaining more and more recognition in the Italian market.

In 1965, FERROLI enters the European market: the Ferroli Espana Sa manufacturing plant is established in the city of
Burgos. In the same 1965, the company acquired the IMA (Industrie Meccaniche di Alano Srl) steel plant in Alano di Piave, Italy, which allowed the company to become independent of iron billet suppliers. Today, the IMA plant produces a full range of aluminum and steel radiators under the trademarks FERROLI and IMA.
The main purpose of gas boilers is to heat water for heating and hot water supply systems in those facilities that are not connected to centralized heating and hot water supply systems. All over the world, this heating equipment is popular among owners of suburban dolmas, dachas, cottages. .

Ferroli wall-mounted boilers are distinguished by high reliability, excellent efficiency and the widest range of settings and controls, which distinguishes it from many other products. At the same time, any Ferroli wall-mounted boiler costs at least no more, and often cheaper than similar products from other European manufacturers.

Gas consumption for gas boilers

The choice of a gas heating boiler is a very serious undertaking that requires consideration of many characteristics; the microclimate in your home, gas consumption, and the amount of heated water for use for various purposes will depend on what equipment you choose. There are a sufficient number of manufacturers, both foreign and domestic, that provide a wide range of heating household appliances, all of which have a different price category and functionality, the use of any equipment leads to completely different fuel consumption.

There are turbocharged and atmospheric gas boilers. Atmospheric gas boilers, according to their standard design, mean that a traditional chimney will be used, which is necessary to remove combustion products. When using this type of equipment, oxygen in the room will also be burned, which can adversely affect your condition. The consumption of such gas boilers is higher, unlike turbocharged ones, which do not need a standard chimney, using a coaxial one, and oxygen in the room will not be burned. Turbocharged gas boilers are slightly more expensive, but you will save a lot on fuel consumption.
There are also single-circuit and double-circuit gas boilers. The single-circuit type is used only for heating rooms of various types, while the fuel consumption will be quite high, it will practically not differ from the gas consumption when operating a double-circuit boiler, which will also provide you with constant hot water supply. Double-circuit boilers will be more economical, since you do not need to buy additional water-heating equipment, and besides, they are quite convenient to use.

Condensing boilers use the maximum amount of thermal energy, which is released when the water vapor produced by the flue gases condenses. This means that the exhaust gases have a sufficiently high temperature, which condensing boilers successfully use. The water entering the boiler will first be heated by the exhaust gases, but only then directly by the gas burner. The cost of such boilers is initially higher than any other, since they are more functional and complex in design, however, during operation you will be able to save from fifteen to seventeen percent of gas consumption, and this will reimburse you for all costs.

Maintenance and repair of gas boilers - a guarantee of safety

If the heating system is based on a gas boiler, this allows you to feel the whole taste of the convenience of an autonomous heating system: the possibility of self-regulation of the temperature regime at home. But, of course, sometimes such complex units require restoration or modernization. Otherwise, a condition dangerous to health and life can be created. A gas boiler repairman is a person who will avoid such situations.

Repair of domestic gas boilers: what you need to know about the device

Any part of the boiler can fail for any reason: poor-quality assembly units, improper operation, an object hit the expansion tank (and now there are puddles under it every day). Be that as it may, the repair of proterm gas boilers or any other must be carried out very carefully, especially if it concerns the security group responsible for proper operation.

At the moment, any master responsible for repairing baxi or other gas boilers knows that the security group consists of the following elements:

Attention! If any sensor fails, you can inhale carbon monoxide, which the system “did not notice”, get an explosion if the electrode does not work properly.

thrust sensor with a plate rated at 75 degrees Celsius. This device monitors the state of the chimney for the boiler, responds to a failure in the removal of combustion products into the chimney, their exit to the smoke traps. As a result, it heats up, works, but it is best if a gas alarm is purchased in addition to it;
monostat to protect turbo boilers from insufficient smoke removal due to a clogged heat exchanger or chimney;
limit thermostat that controls the water in the boiler. If it boils, the overheating sensor turns off the boiler;
ionization electrode to control the presence of a flame. Quite often, the repair of viessmann gas boilers begins precisely with checking the electrode, since the operation of a gas boiler without a flame can even provoke an explosion.
blast valve for pressure control. At pressures above 3 bar, the system will force the boiler to dump dangerous excess.

Gas boiler automation repair: what you need to know about control boards

Some types of gas boiler repairs can only be performed by specialists. By the way, in order to prevent the breakdown of the boiler, you must not forget about the UPS for the gas boiler. No matter how skilled the owner himself is, where such a unit is located, the variety and complexity of the automatic control and management system for the boiler does not always allow a person without experience to correct the operation of the boiler. Repairing a Danko or Viesmann at the level of correcting the operation of the board also sometimes requires special equipment, which the owners simply cannot have.
The operation and repair of gas boilers from different manufacturers will be different, but, as a rule, electronic boards have much in common in their principle. Repairing control boards for gas boilers is quite difficult for a novice master, so experienced professionals can tell you some of their secrets to setting up boards.

Important Repair Notes

Firstly, you should never immediately apply full voltage to it, otherwise the repair of vaillant or Zhukovsky gas boilers may end there: a complete replacement of the burned-out automation for the boiler will be required.

It is better to connect all sensors with "correct" data that are used in the operation of the boiler. And in order to avoid surges, use a voltage stabilizer for a gas boiler. In the instructions for a particular boiler, all indications will be indicated: as the next sensor is connected, it will be possible to see where the system “sags”.

For example, if you need to check how the voltage is applied to the gas valve, first the board is tested taking into account the operation of the controllers. Then you should check the sensors of the security groups for an open contact. After that, the board is given a task to work: to ignite the boiler. The pump is turned on in sequence, then it is controlled how the liquid or antifreeze circulates. When the turbine is turned on, it will be possible to see if there is a false flame. Only then can you apply voltage to the board. If the unit is malfunctioning, then the repair of vaillant or baxi gas boilers may not end there.

Training for the repair of gas boilers in the field of setting up automation (especially control boards) lasts more than one week. This is due to the fact that a malfunctioning boiler can cost the life of its owner: therefore, the work of a specialist is akin to the work of a doctor responsible for the existence of his patient.

Do-it-yourself gas boiler repair: is it worth it?
A modern gas boiler is a complex system, the main danger in the event of a malfunction is the use of explosive fuel, gas. To control the operation of a heating double-circuit or single-circuit heating unit, automation is included in the boiler system, which supports optimal operation. Therefore, the repair and maintenance of gas boilers is carried out only by specialists, although some components of the system can be replaced independently.

If there is a smell of gas or smoke in the room, you can only turn off the boiler completely, ventilate it and leave the room by going to the next room. Repair of baxi or other gas boilers must be carried out by a specialist who must be called immediately.

In the event of a breakdown of the combustion sensor or the supply gas pipe, turn off the device, allow the boiler to cool down, close all gas valves. Then be sure to check the room for the smell of gas! If there is draft, you can start the boiler again. If there is no draft, turn off everything and wait for the master: repair of navien or Vaillant gas boilers is required.

Important! If the boiler overheats, which is a very common occurrence, then the repair of AOGV gas boilers will include cleaning the heat exchanger or correcting the automation. When the overheating sensor is triggered, immediately turn off the boiler and call the masters.

Do-it-yourself repair of a gas boiler can only be carried out in case of visible and easily repairable damage, as well as if the gas supply pipe is dirty. It can be washed with water, cleaned with a cotton swab and dried.

GAS BOILER CARE

Modern gas boilers are, in fact, small autonomous boiler rooms. Gas boilers, like any heating equipment, require care and attention: place in a dry and clean place, supply high-quality fuel and regularly clean the boiler.

Caring for a gas boiler is very important, because every owner wants his boiler to work for a long time, efficiently and without accidents. But in order for the boilers to work reliably, the user must comply with a number of conditions.

The first of them - the room should be dry. Steel and cast iron parts of the boiler are subject to intense corrosion. So organizing laundries and dryers in the same room with the boiler is highly undesirable.
The second condition for caring for a gas boiler is to protect it from dirt and dust. It is necessary to carry out dirty and dusty work at a considerable distance from the boiler, because dust and dirt that has settled on the heat exchanger significantly reduces efficiency.

An important condition is the quality of the water. Water should be clean, free of air, dirt and rust. All these negative factors can significantly affect the operation of the boiler and clog the heat exchanger. To avoid trouble with heating, it is necessary to install a cleaning filter on the system, which will trap all contaminants and prevent them from reaching the boiler. It is necessary to minimize the contact of water with atmospheric air so that less oxygen enters the system, which is the main cause of corrosion.
The fourth condition is the quality of the fuel. Do not buy fuel for the boiler of dubious quality, even if it is cheaper. Such savings can damage the boiler.

A necessary condition for operation is to carry out thorough maintenance and inspection of the boiler once a year. It is also necessary to clean the filters of contaminants that have circulated in the water. To do this, close the taps on both sides, open the filter cover, clean and rinse the filter element.

The owner must take care of checking the condition of the chimneys and ventilation ducts. If necessary, contact a specialized organization to check them and issue a conclusion on suitability for use. The heat in the house depends not only on the state of the gas boiler, but also on the state of the heating system as a whole, therefore it is recommended to carry out: flushing the heating and hot water supply system with special cleaning solutions in order to remove deposits from the internal surfaces of pipelines; elimination of leaks in the heating system connections; replacement of worn parts of the heating system.

It is important not to forget that the boiler burner, which is subjected to high temperature loads, also needs careful maintenance. Regular cleaning of the burner will help to avoid excessive fuel consumption and premature failure of the entire device. Take care and maintain your gas boiler. Caring for a gas boiler will enable the equipment to serve for more than a dozen years. Processed

The device and principle of operation of Ferroli boilers

Ferroli gas boilers are of high quality and reliability in operation. They can operate on natural and liquefied gas. The operation of the boiler can be controlled directly from the device and remotely. Equipped with a self-diagnosis system, which minimizes human intervention.

They have a high efficiency of 92%. The principle of operation of Ferroli boilers is to heat the heat exchanger with thermal energy obtained as a result of gas combustion. A distinctive feature is the presence of a microprocessor control system, with the help of which the flame is controlled.

The copper heat exchanger is coated with an anti-corrosion aluminum composition, this type of heat exchanger is patented by Ferroli. The combustion chamber is steel or copper, covered with anti-corrosion aluminum composition, with an internal environmental coating.

Equipped with an injection burner, the heads of which are made of stainless steel. The most popular models on the market are the double-circuit boilers Diva, Divatop, Domiproject and Ferroli Domina 24.

Boiler Ferroli Domina 24

Domiproject has a "pipe in pipe" bithermic heat exchanger, a by-pass circuit in the heating system, and a display on the front panel. Domina is equipped with a copper bithermic heat exchanger of increased power, by-pass system, light indication. Operates on both natural gas and LPG.

Basic error codes

During the operation of the boiler, failures and malfunctions may occur, the codes of which are displayed on the display of the device. Error codes with the symbol “a” lead to the blocking of the boiler, they can be reset manually by pressing and holding the REZET button for 1 second. Codes with the symbol "f" are reset automatically, after the malfunction has been eliminated. The most common malfunctions on the Ferroli gas boiler are: lack of ignition (a01), smoke thermostat operation (f04).

01

Error 01 - no ignition of the burner, the boiler does not turn on. Possible causes and how to fix them are described below.

No gas flow:


Faulty ignition electrode:


On Domina boilers, when this code occurs, two indicators do not light, red flashes.

02

Error 02, blocking - a false signal about the presence of a flame when the burner is off on the Ferroli, Domina and Domiproject models, the reasons for its occurrence:

Faulty ignition electrode:

  • Inspect the wires connecting the electrode and the board, measure the circuit between them for a short circuit.
  • Check gap between electrode and burner, adjust if necessary.

The control board may be defective. in this case, it must be replaced. On Domina boilers, when this code occurs, one indicator is off, yellow is on, red is flashing.

03

Error 03 means boiler overheating, appears if the thermostat has overheated. The code will not appear if the burner was not working at the time of overheating. The safety device is activated when the temperature in the heating circuit exceeds 90 degrees, and the temperature of the hot water supply is more than 95 degrees.

Ferroli boiler thermostat

In the Ferroli Domiproject C24 mounted models, the sensor is triggered at a temperature of 105 degrees. If the unit does not start after cooling down, the following malfunctions are possible.

Sensor failure:

  • Wait for the unit to cool down and restart it.
  • Inspect the mechanical connections of the sensor, troubleshoot.
  • Check the sensor for a short circuit and open circuit, if defective, replace.

The circulation pump is running at partial power:


No coolant circulation:


On Domina boilers, when this code occurs, one indicator does not light, green flashes, red flashes

04

Error 04 appears when the smoke exhaust thermostat is triggered, the burner goes out, the boiler is blocked. After 20 minutes, the automation checks the thermostat, if its contact is closed, the boiler remains in a blocked state.


8

Error 8 or error f08 appears when the heat exchanger overheats, when the coolant temperature exceeds 99 degrees and disappears at a temperature of 90 degrees. This code appears before code 03, is not fixed on the display, can only be seen in the code history. Causes and remedies are the same as when code 03 appears.

51

Error 51 indicates problems with smoke removal. The causes and remedies are similar when code 04 appears.

a01

Error a01 - no ignition of the burner on models with a display, the boiler does not turn on. Why it appears and how to eliminate it is described in code 01.

a03

The reasons for the appearance of error a03 are the same as for code 03 on boilers with light indication, it is eliminated in the same way.

Boiler temperature control

a06

Error a06 lights up in the absence of a flame some time after ignition, when the flame goes out 6 times within 10 minutes.

Occurs in the following cases:


a08

Error a08 is overheating of the heat exchanger. Why it appears and how to fix the situation is described above in the description of error 08.

a21

Error a21 means a malfunction of the combustion control system on Ferroli Domiproject boilers. With this error, the boiler may periodically light up and fade.


a51

Error a51 warns of problems in the smoke exhaust system. See the description of error 04 for the reasons for its appearance and ways to solve the problem.

d1

Error d1 is not a malfunction of the boiler, the code means a delay before the next start.

d2

Error d2 is not caused by any malfunction, this parameter means the waiting time before the next heating cycle of the heating system.

d3

The parameter d3 is not an error, it means a waiting time, about 50 seconds, before the next ignition.

d4

Before restarting the boiler, the display shows the code d4, which is not an error, it means a pause between starts of 5 minutes.

f04

Error f04 appears in Ferroli Domiproject DC devices if the exhaust gas removal thermostat is overheated.

Exhaust thermostat

  • Broken chimney draft. Clean out the chimney.
  • Chimney installed incorrectly. During installation, it is necessary to take into account the design features that exclude air turbulence and reverse flow.
  • Sensor failure. Check the mechanical connection of the sensor wires to the control board. Check the sensor with a multimeter, if necessary, replace it.
  • Faulty board. If all of the above is in good condition and after restarting the boiler gives the same error, check the board, in case of a malfunction, replace it.

f05

When the boiler is started, the fan does not turn on, the system generates an error f05 (f05).


f10

Error f10 indicates a sensor malfunction in the supply circuit.

  • Sensor damage. Ring the sensor contacts, if it is faulty, replace it with a new one.
  • Short circuit or open circuit in connecting wires. Check with a multimeter for a short circuit, check the reliability of the connections.

Ferroli gas boilers have earned the trust of consumers and are now positioned as high-quality equipment from Europe. The company itself is one of the world's leading manufacturers of heating equipment.

In a private home, Ferroli boilers always provide the latest in performance, reliability (MTBF) and user friendliness (ergonomics, noise, convenience ...).

What is Ferroli - history

The company for the production of boilers was founded by the Ferroli brothers in 1955 in the Italian city of San Bonifacio (Verona). The first order is the supply of gas-fired steel boilers for municipal houses in Verona.
In the future, thanks to perseverance, resourcefulness, the creators managed to significantly expand the company, turning it into a leading manufacturer.

  • In 1962, Ferroli introduces cast-iron boilers to the market, for the production of which an automated casting process was created.
  • In 1967, an automatic line for the production of cast-iron radiators was put into operation on new automatic lines.
  • 1973 - a factory for the production of steel and aluminum radiators, ... etc. started working.

Now Ferroli assembly plants are located in Italy, Germany, Spain… The company supplies a range of modern equipment:

  • heating boilers;
  • climate systems;
  • shower cubicles;
  • radiators and heating equipment;
  • electric motors.

Classification of models, names of Ferroli boiler lines

Wall mounted boilers:

  • diva,
  • Domina N,
  • arena,
  • Divatop Micro,
  • Divatop-H,
  • Divatop Micro LN,
  • Divatop 60,
  • Domiproject-D

Floor units, - examples of models:

  • Pegasus-56,
  • Pegasus-2S,
  • Pegasus D,
  • atlas,

Condensing options:

  • econcepttech,
  • econcept-ST,
  • energy top,
  • econcept combo,

Features of the most economical condensing boilers

In Europe, condensing boilers are required to be used at the legislative level. Since these devices save energy and pollute the environment less.

In the technical specifications of the condensing boiler, you can find that the efficiency is estimated to be more than 100%. This technical nonsense is obtained because the boiler uses the energy of the phase transition of water from vapor to liquid. This energy is not taken into account when determining the calorific value of fuel combustion. Thus, there is a fuel saving of 10 - 25%, depending on the ability to fully use low-temperature heating.

The fact is that the boiler will operate in a super-economical mode only at low coolant temperatures - the heating system in the house must be appropriate. You can learn more about such heating on this resource ...

In addition to collecting energy from water vapor, Ferroli condensing boilers use other innovations - the best automation, weather-dependent control, the latest materials and equipment ...

But it is in our conditions that the increased price makes them weakly competitive, and the reason is low energy prices ...

Modern models of gas boilers Ferroli

Consumers in the recent past have had popular models of gas boilers Domiproject-D and Divatech-D. Now they have been replaced by model lines called Diva, Domina and others. But it is likely that these lines of European-quality gas heating equipment will be replaced by more advanced models in the near future ... After all, the company shows dynamic development and constantly updates its lineup.

More often at Ferroli you can find double-circuit versions of boilers, where hot water is prepared in a second additional heat exchanger.

Power is presented in a wide range, for example, wall-mounted automated gas heat generators can easily cover the heat needs of private houses and apartments. A power step of 4 kW will allow you to choose the right option in the model range - ... 20 kW, - 24, 28, 32 ...

Open and close combustion chamber

Design features of the modern range of heating boilers from Ferroli - the ability to purchase the same model with either an open or a closed combustion chamber. Options with an open chamber are indicated in the names with an additional letter "C". The option with a closed (forced) burner is marked as "F".

Often, consumers ask the question, which boiler is better - with an open or closed burner. The answer is known - both are good for their conditions. Atmospheric open burner operates under the influence of chimney draft, takes air from the room, it can only be placed in a special furnace, with a regulated fresh air inflow, and a high chimney that creates the necessary draft.

A boiler with a closed forced combustion chamber can be located in any non-residential premises, for example, in the kitchen, and the air will move through the burner under the action of a fan along the same double pipeline - fresh from the street, exhaust gases back.

Line of wall-mounted boilers Domina-N

The Domina-N model has a copper heat exchanger with a particularly resistant coating, which is claimed to have the longest trouble-free operation.

Modulating burner, change of heating power and domestic hot water floor by microprocessor control. Low-noise injection burner made of AISI 304 stainless steel.

Diva

The Ferroli Diva line, like other modern models, is equipped with a copper heat exchanger with an aluminum alloy coating, which is considered to be very resistant to thermo-chemical aggression. Information liquid crystal display, a large degree of automation and self-diagnosis. As well as other achievements of modern technologies used on Ferroli boilers:

  • electric ignition without igniter;
  • frost protection system;
  • water hammer protection;
    And much more.

Divatop Micro

The Divatop Micro range is a small wall-mounted boiler with the latest innovations. Provides programming for a long period of operation.

  • Possibility to connect Romeo remote control;
  • Possibility to connect Oscar room programmer device;
  • the ability to operate both on liquefied and natural gas (subject to the use of a special kit).
    As well as all other achievements of the company…

Reviews that say about Ferroli boilers

Boilers of this brand have been in operation for a long time, a lot of reviews have appeared, which basically indicate that we are talking about high-quality European equipment.

Note first of all:

  • general ergonomics that meets the highest modern requirements;
  • the use of parts, materials of the highest quality, from other leading world manufacturers. For example, there is a Siemens valve ...;
  • relatively quiet operation;
  • long maintenance-free service life, reliability.

Negative reviews about Ferolia boilers that can be found are mainly associated with poor gas quality and unstable power supply:

  • high gas consumption - but it is equally increased in the gas stove, to heat the kettle;
  • the ignition of the burner occurs with cotton, - it is difficult to ignite the gas on the stove ...;
  • failure of the electronics - turning on the boiler without a protective voltage stabilizer, which the trading organization warns about, and without which it does not give a guarantee for the equipment ...

Today, a gas boiler is a necessary thing in every home. Every year, the inhabitants of our country have to deal with planned and unscheduled shutdowns of hot water. And private houses and many new buildings, in general, are designed only for individual heating. As a result, sooner or later, many of us have to think about purchasing a boiler or boiler. This article will focus on Ferroli gas boilers. Let's talk about the types of heaters, their operation and possible breakdowns.

Kinds

Ferroli is an Italian company that produces various household appliances from heaters to a variety of air conditioners. For the first time she declared herself in the middle of the last century. Over the decades of its work, Ferroli has become an international company that has branches all over the world, including Russia. In our country, their products are known for their high quality and affordable price. Heaters are the main layer produced by the technology company. Basically, their varieties depend on the source of nutrition. Accordingly, they are:

  • gas;
  • electric;
  • solid fuel;
  • diesel.

This article will focus on gas boilers. They, in turn, are also divided into subspecies according to their parameters. Let's look at them in more detail.

  • single circuit- the simplest version of the boilers. Designed exclusively for space heating. They are not able to heat water, which means that in addition you will have to purchase other equipment. But single-circuit boilers have high reliability, which is provided by the internal device. Its main elements include a heat exchanger, expansion tanks and circular pumps.

  • Dual circuit- Solve the issue with the purchase of additional equipment for heating water. This equipment is aimed at performing two tasks at once. These heaters are equipped with two heat exchangers. The water that circulates through the heat exchanger serves not only to heat the room, but also to provide hot water.

It is worth noting: a double-circuit boiler does not exceed in size a single-circuit one. But due to the complex structure, the level of reliability decreases. By the way, there is a bithermic subspecies of double-circuit boilers. Its peculiarity lies in the fact that one heat exchanger is located inside the other. With this structure, boilers become the least reliable.

  • Open combustion chamber- heaters that need an influx of oxygen coming from the external environment. Therefore, the occupied premises must be equipped with ventilation and a chimney. The latter is necessary to remove combustion products. Before installing such a boiler, the room will have to be prepared in accordance with all fire safety rules. This type of boilers has a simple structure, high reliability, low productivity. Models make little noise during operation.

  • Closed combustion chamber- such boilers are the least harmful to the environment. They work with a special burner. Among other parts, they have a fan that supplies air. It also removes combustion products, so it does not matter if there is draft in the chimney or not. This type of boiler is the most productive, but less reliable. Often there are problems with the fan. By the way, it makes a lot of noise during operation.

Many of these models are condensing. That is, they differ in low fuel consumption with a fairly high efficiency. Others (convector boilers) lose a lot of heat along with combustion products, which is a serious disadvantage.

  • wall- the most popular type of gas boilers. The demand for them is due to their compact size, affordable price and sufficient performance to heat an apartment or a private house. They are also easy to install due to their light weight. This type usually has a closed combustion chamber.

  • floor standing- a powerful type of boilers, designed to heat large rooms. Their dimensions and weight far exceed the parameters of wall heaters. The price is also noticeably higher. Such boilers are rarely used in everyday life.

The lineup

Ferroli brand products boast a wide range of different models. You can choose a heater based on any requirements. However, not all of these models can be presented in Russian household appliances stores. Fortunately, today Internet services with a delivery service can always come to the rescue. Consider the most famous and common boilers from Ferroli.

  • Domina N- one of the new models released in 2013 to replace the old boilers that were discontinued. The unit belongs to the bithermic subspecies, that is, it has two heat exchangers and the second is located inside the first. They are made of copper and coated with a heat-resistant substance that increases the service life. Wall-mounted boilers of this model can have both a closed combustion chamber and an open one. Domina N has a long range of advantages, including: nice design, small size and weight, electric ignition function, anti-blocking pump system, frost protection, the ability to connect a remote control, high efficiency, safety and reliability.

  • Ferroli Diva- Another modern wall-mounted boiler. It has two heat exchangers to heat the room and provide hot water. Equipped with a simple and accessible control panel with a digital display. Like the Domina N model, it has subspecies with different combustion chambers. Among the advantages of Ferroli Diva are elegant appearance, ease of installation and maintenance, electric ignition, 93% efficiency level, self-diagnosis, safety, plate heat exchanger for hot water, anti-corrosion coating of the steel combustion chamber, and an electronic board for power modulation.

  • Divatop Micro- the latest of the models, featuring a number of innovative features. Quite a popular boiler today. Boasts improved efficiency and reliability. Consists of two separate heat exchangers made of copper. And three-way inverter valves provide ease of use. The boiler program is able to independently maintain the set temperature for a long time. This model has an innovative self-diagnosis system that ensures maximum safety of operation.

The price of Divatop Micro may seem too high compared to analogues, but at the same time the boiler is equipped with a full range of accessories that make it much easier to manage. Other features include a variable speed fan, LCD display, automatic weather recognition system, wide functionality and convenient layout of internal components.

  • Pegasus 23- a popular model of floor boilers. Of course, they are chosen less often than wall-mounted ones. The point is the high price and power, which is not needed to heat a house or apartment. But some people own large cottages that are not easy to heat with a medium-sized boiler. Here Pegasus 23 comes to the rescue, whose power reaches 23 kW. The cost of the model can reach 50 thousand rubles. It is due to the presence of a cast-iron heat exchanger, which ensures maximum reliability of the boiler. It is also resistant to corrosion. The boiler is equipped with elements such as a thermometer and a pressure gauge.

  • Bluehelix Tech 35A- wall-mounted boiler, superior in power to some floor-standing ones. Designed specifically for heating large rooms. The model is a condensing type heater. The type of combustion chamber is closed. Maximum power - more than 32 kW. At the same time, the boiler is very reliable. At the heart of Bluehelix Tech 35 A is a heat exchanger made of stainless steel. In addition to it, an 8-liter expansion tank and a circulation pump are available. The filling dictates a solid price - about 65 thousand rubles.

  • Atlas D30- An interesting model that can run on both gas and liquid fuels. This boiler is single-circuit and has a cast-iron heat exchanger. And its thermal insulation is made of mineral wool. The maximum power of the unit is 30 kW. Among the advantages, one can single out a high level of efficiency exceeding 93%, the ability to connect an additional boiler or other external panels, as well as a low amount of electricity consumed. However, there are also certain disadvantages. To use the boiler, you will need a mounted burner, which will have to be purchased separately.

  • Fortuna PRO 24F- one of the most popular wall models. It boasts positive feedback from the owners of private houses, because the unit is intended for their heating. It is able to provide heat to an area of ​​240 square meters. In addition, the boiler will please you with hot water supply. Maximum power - 25 kW, efficiency - 93%. The heat exchangers inside it are separate. The type of combustion chamber is closed. There is an expansion tank of eight liters. By the way, if desired, the heater can be converted to work on liquefied gas.

  • Econcept Tech 18A- stands out from other models with its flexible adjustment system. But alas, it is not able to boast of high power, whose maximum does not exceed 18 kW. The same can be said about the average reliability indicators. This is due to the aluminum alloy from which the heat exchanger is made. But among the advantages, an increased level of security can be distinguished. It is achieved by the self-diagnosis function, automatic air vent, safety valve, electronic flame modulation and other useful systems.

Launch and control

Most modern models are equipped with automated control systems. And if not, they can be purchased separately and connected, which will greatly simplify the operation of the boiler. To properly start a gas heater from Ferroli, you must first connect it to the mains and turn it on by pressing the start button. It may take about 15 seconds for the boiler to start up. Then open the burner and ignite.

To turn off, close the valve and press the corresponding button. It is also recommended to disconnect the boiler from the mains, however, when completely disconnected, the heater may freeze. To avoid this threat, you need to drain the entire water. You can also add antifreeze to it.

Remote controls make it much easier to set up the job. Moreover, the adjustment in all models is carried out according to the same scheme. You can install such a remote control in any room, and you do not have to visit the boiler every time you need to change the parameters. You can manually change the room temperature or the heat exchanger temperature, set a specific operating mode, activate the comfort function or reset all preset settings.

Also with its help you can give commands to the boiler sensor and set the expansion tank settings. And the digital display, which is almost always present on the remote, will notify you of errors that have occurred. This feature greatly simplifies maintenance. Accordingly, the service life is increased.

Faults and repairs

Even if your boiler is of European quality and enviable reliability, sooner or later you will encounter certain breakdowns. But don't worry. Any modern model will try to notify you about this and tell you exactly what the malfunction is. She does this using a display or color indication. In the second case, the indicators on the control panel start flashing. Why does the boiler not heat water and the red light is flashing? What does bad ignition mean? Answers to these questions and a detailed designation can be found by referring to the instructions or special Internet sources.

Consider the error codes that are displayed on digital screens.

  • A01 - no flame. This error means that the system made several attempts to start the fire, but none of them worked. Valve closed or gas pressure too low. Also, the problem may be the incorrect connection of the electrodes. Examine the wiring. If everything is in order, restart the equipment. The operation of the control board may also be disrupted.

  • A03 - the boiler has overheated. The alarm sensor registers an elevated temperature and shuts down the equipment until it returns to normal. The reason is often a violation of the circulation of water. This happens due to low pressure or when air enters the system.

Keep in mind that the sensor itself can also fail and register incorrect readings. In this scenario, it should be replaced.

  • A06 - ignition has been carried out, but there is no torch. This error occurs when the gas pressure is low.
  • A08 - the overheating sensor is out of order. First of all, check its wiring for breaks. If everything is in order with it, the sensor must be replaced.
  • F05 - the process of removing smoke from the room is violated. Usually the problem is with the air pressure switch. Pay attention to the correct connection of the connections.

Also, the problem may lie in the heater diaphragm. However, most often the code is displayed due to a clogged chimney. Just do some cleaning.

  • F10 - two reasons. The first is a short circuit. The second - somewhere in the temperature sensor circuit there was a break. Check if there is contact between the sensor and the control panel. The problem is solved by reconnecting the wiring. Find out the current resistance of the sensor. If it is faulty in all respects, replace it with a new one.
  • F14 - a problem with the second pressure heating circuit sensor. Most likely, it is damaged and needs to be replaced with a new one. Either there is a short circuit or a break.

  • F34 - the voltage of the electrical network is too low. The boiler gives an error when it drops below 180 V. If the problem occurs too often, it is recommended to connect the boiler to a stabilizer.
  • F37 - the pressure level has noticeably decreased in the heating system. The relay contacts open. If there is a problem, replace it. And inspect the entire heating system, leaks may be found in it.

  • F39 - a short circuit or open circuit of the outdoor temperature sensor has occurred. Check resistance and wiring between sensor and control panel.
  • F50 - the gas valve modulation coil is defective. It should be called to identify an inter-turn circuit or open circuit. Check gas valve. Maybe there is an error in the operation of the control panel. Perform a reset.

Some of the problems can be eliminated with your own hands. For example, to release air or increase pressure is a simple matter. You can clean the heat exchanger if you already have experience in this matter. But in most cases, it is recommended to call a specialist or contact a service center. Masters will conduct detailed diagnostics and troubleshoot without causing harm to the system. And in order for breakdowns to occur as rarely as possible, a few simple rules should be followed. Perform maintenance and cleaning at least once a year. Replace damaged parts to avoid more serious damage. Don't skimp on installing a heater. Entrust this business to the masters who will do everything right.

Gas boilers of the Ferroli trademark are especially widespread in the domestic market of heating appliances. Not least due to their moderate price, which at the same time corresponds to the good quality of these products. Ferroli has been manufacturing products since 1958.

Thus, it is worth assuming that all consumer novelties are reflected in the products of this brand in a timely manner. Instructions for using Ferroli gas boilers, which can be found below, will help you understand the application.

Features of this product line

The basis of the model range of wall-mounted gas boilers of the trademark are the Diva and Domina N units, which have been supplied since 2013. The main technical characteristics of products of approximately the same power are given in the table.

Such an overview of Ferroli gas boilers shows that both sizes belong to the double-circuit category. These are products that provide guaranteed heating of rooms up to 100 sq.m. and hot water supply.

The external characteristics of such boilers generally correspond to the model range, while their dimensions are one of the smallest among analogues. Reviews of Ferroli gas boilers indicate primarily their compactness. Appliances can be installed even in small kitchens, which is an undoubted advantage of these products.

The budget design of products from the Ferroli trademark was manifested in the fact that the Diva series units are equipped with pressure control sensors - pressure switches - only optionally, as well as some other diagnostic devices.

It is assumed that the automation system, adjusted to certain operating conditions, will itself quickly respond to changes in pressure, pressure and other parameters that affect the normal operation of the boiler. In fact, everything is determined by the quality factor of the conditions of transportation and installation.

Analysis of some design solutions


Since the market for domestic gas boilers is quite densely filled, it is always possible to compare the main operating parameters of competing boilers. In units from the Ferroli trademark, the injection burner heads are made of AISI 304 stainless steel (for comparison, AISI 310S steel is used in German-made boilers).

Significant disadvantages of AISI 304 steel are its inability to withstand elevated temperatures for a long time, as well as insufficient mechanical strength. For comparison, we present the chemical compositions of both steel grades indicated above, precisely from the point of view of the required durability:


A comparison of the chemical composition clearly shows that although formally both steels belong to the low-carbon class, the strength of AISI 310S steel is 40% higher than that of AISI 304 steel. AISI 304 short term up to 900°C and long term up to 600°C.

There are similar questions regarding the chosen material of heat exchangers: Ferroli boilers use aluminum alloy, while similar products from Vissmann use cast iron. Although this circumstance somewhat increases the mass of the boiler, the durability of cast-iron heat exchangers is almost 1.5 times greater than the durability of aluminum ones. Some models use copper heat exchangers, but their strength is inferior to cast iron. Such a solution can cause malfunctions of Ferroli gas boilers.

Burner type


The devices from the Ferroli trademark use a conventional atmospheric burner, the parts of which are characterized by sudden temperature changes during operation. This provokes thermal deformation, accompanied by a change in size with a subsequent risk of developing microcracks. Fan burners, implemented in the designs of German gas boilers, operate with constant water cooling, which:

  • increases the service life of the burner;
  • reduces the emission of harmful gases into the atmosphere to European fixed environmental standards.

Of course, the operating instructions for Ferroli gas boilers are silent about these, as well as other design features of these units.

Aggregate Capabilities


Instructions for Ferroli gas double-circuit boilers describe some features of the start-up process, as well as the operation of control systems. Here is the instruction manual.

  1. To turn on, open the gas valve, then turn on the power.
  2. Set the knobs that regulate the temperature of heating and hot water to the desired position. After that, the boiler will automatically turn on when the room temperature drops or when hot water is needed.
  3. If you turn both knobs to the minimum, the boiler will not work, but it still consumes power. This is due to the "anti-freeze" function, which turns on the heating of water in the heating system in case of a strong drop in ambient temperature. The signal lamps do not light up.
  4. By adjusting the knobs, you can set the summer or winter modes.
  5. There are three modes: Summer (hot water heating only), Winter (heating and DHW), as well as a mode in which DHW is turned off and only heating works.

It is worth knowing some of the nuances of starting the heating system. They are listed below.

  1. Ability to work on any type of gas - liquefied and natural.
  2. Chimney frost protection. At the same time, the instructions contain an indication of draining water from the corresponding circuits when the boiler is not working in the winter.
  3. Electronic ignition and a microprocessor control system for the operation of the boiler is a really useful technical innovation. Its implementation allows avoiding unnecessary risks in case of insufficient qualification of the user of the heating unit.
  4. Ferroli boilers are not equipped with shut-off valves, which increases the risk of flooding the premises when the pressure in the network is exceeded, when the unit is turned off, but the coolant supply does not stop.
  5. Quite complicated is the process of installing adapters to chimneys. Instructions and photos of Ferroli gas boilers show the replacement algorithm and sequence. But the complexity of the calculations requires calling a specialist who has a license to work with these units, since some initial data are not given in the instructions.

Typical malfunctions

The above features predetermine the malfunctions characteristic of the Ferroli gas double-circuit boiler. Among the most common breakdowns in people, the following can be distinguished.

  1. The Ferroli gas boiler does not turn on - such a malfunction may occur due to a lack of gas in the network, the presence of air in the pipelines, a malfunction of the gas valve or the ignition electrode.
  2. In the Ferroli gas boiler, the water pressure drops. A malfunction of the circulation pump is the main reason. In the absence of a pressure switch (but in the presence of a coolant in the system), such a malfunction may occur when the ignition power is insufficient, which should be increased. It is also possible that there is damage to the electronic control board of the boiler.


Many reviews note the modern design and appearance of products, which is generally typical for any Italian goods. However, it is indicated that the products are not very reliable. At one time, such a malfunction of Ferroli Domiproject F24 gas boilers became the main reason for their removal from production. However, the new line of models is not much superior in quality to the previous one.

Malfunctions of heating systems are often repeated in new models. The reviews note the insufficient development of after-sales service: existing specialized repair companies do not know the design of boilers well, and optional products for them (for example, a boiler connection control sensor, etc.) are very difficult, if not impossible, to purchase.


Particularly unreliable are the components of the circuit responsible for the operation of the water heater: electronic boards often fail, the heat exchanger is unstable, and a gas valve has to be used to adjust the water temperature. At the same time, prices for Ferroli double-circuit gas boilers depend on their power and start at 30,000 rubles.
