Italian gas heating boilers Ferroli are only a small part of the range climate control equipment, which is produced at the enterprises of this company. The Ferroli company itself was founded in 1955 in small town San Bonifacio, and since then it has grown from a small factory into one of the leaders in the national and European heating equipment market.

Boilers from Ferroli

Wall and floor models

Despite the very a wide range of installations for heating residential and production premises, the lion's share of Ferroli's profits comes from gas heating boilers– wall and floor. At the same time, it is in the wall-mounted segment that the greatest diversity is observed.

This is due to the fact that compact wall models have a number of advantages in use:

• Firstly, such a boiler can be installed directly in a residential area, since it does not require a separate boiler room.
• Secondly, If previously the power required for heating could only be provided by large-sized installations, today, through the use of modern technologies even a small boiler can heat up to 300 square meters living space.
• Easy to install– another argument in favor of choosing small models mounted on load-bearing wall premises. Of course, you shouldn’t install the boiler yourself, since this requires special permission - but the cost of installation directly depends on its complexity!

Advice! So that you can monitor compliance with the installation quality heating device, we recommend that you study the video posted on our website. Any work requires verification, and without the proper knowledge you will not be able to carry it out!

Price also plays an important role. Although Ferroli products cannot be considered the cheapest price segment, but still among the mounted models you can choose a completely affordable option.

Application and equipment

Ferroli boilers can be used in the following areas:

• Firstly, for heating private houses and cottages. As we indicated above, the power is quite sufficient.
• Secondly, the compact dimensions allow these units to be used even in apartment buildings for organizing individual heating.

To effectively implement these functions, Ferroli installations are equipped with the following equipment:

• Combustion chamber open or closed type(respectively, they are marked C or F).
• Bithermic heat exchange tank made of copper alloy.
• Automatic control system for the burner operation on a meringue microprocessor unit.
• Protection against freezing, overheating or internal scale formation.

Also included in the basic package is a unit responsible for flame modulation and an ionization system for controlling combustion intensity. Thanks to this, Ferroli boilers are completely protected from possible gas leaks.

The appearance of the boilers, as well as the location of the main elements, are shown in the photo. The instructions included with each product clearly demonstrate the process of connecting the boiler to the network, as well as the sequence of adjusting its main functions. should be done only by specialists, and no amateur performances!

— three-phase 380 V (from 12 kW and above).

Electric boilers "Ferroli Zews"

The assembly of electric boilers is carried out at a factory in China under the quality control of Italian specialists, this is indicated to us by the product barcode 693. This can be attributed to the disadvantages, because Russian consumers do not always trust the reliability of a product made in China. But there are also advantages, for example, the price of a Ferroli electric boiler assembled in Italy would be much higher than a Chinese one.

The design of the Ferroli Zews electric boiler and its functions

All boilers of the “Zews” series are single-circuit, designed only for heating. However, they provide the ability to connect an external boiler indirect heating for hot running water.
On the boiler control panel there is also a special knob for regulating the temperature of the water, which is heated in this additional boiler.

In addition, the boiler has a built-in water and air temperature sensor. However, in order to control the operation of the boiler depending on the room temperature, you must additionally buy an external one.

You can also connect weather-sensitive automation by installing a special sensor outside temperature, for which the boiler has its own connector. With such weather-sensitive automation, you can significantly save on electricity, significantly reducing its consumption.

Having analyzed the technical characteristics, device and functions electric boiler Ferroli, we can conclude that this is a modern heating apparatus, meeting all the latest technology requirements. Its only drawback is that it is slightly overpriced compared to its competitors. Yes, and reviews from specialists and customers are not yet enough to really evaluate the quality of Ferroli Zews electric boilers. Let's watch the video.

The FERROLI company was founded by Mr. Dante Ferroli in the Italian city of San Bonifacio in 1955. The products of a small workshop in which gas boilers were produced were a success among city residents, 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 fame and are increasingly recognized in the Italian market.

In 1965, FERROLI entered the European market: it was founded manufacturing enterprise Ferroli Espana Sa in the city
Burgos. Also in 1965, the company acquired the IMA steel mill (Industrie Meccaniche di Alano Srl), in Alano di Piave, Italy, which allowed the company to become independent from suppliers of cast iron billets. Today the IMA plant produces a full range of aluminum and steel radiators under 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 it's heating equipment popular among owners of country estates, dachas, cottages .

Ferroli wall-mounted boilers are highly reliable, have excellent efficiency and the broadest possibilities 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 similar products other European manufacturers.

Gas consumption for gas boilers

Choice of gas heating boiler 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, who provide a wide range of heating household devices, they all have different price category And functionality, the use of any equipment leads to absolutely different consumption fuel.

There are turbocharged and atmospheric gas boilers. Atmospheric gas boilers in their own way standard device imply that a traditional chimney will be used, necessary to remove combustion products. When using this type of equipment, the oxygen in the room will also be burned, which can negatively affect your condition. The consumption of such gas boilers is higher, unlike turbocharged ones, which do not require a standard chimney, using a coaxial one, and oxygen in the room will not be burned. Turbocharged gas boilers are slightly higher in price, but at the same time you will save significantly on fuel consumption.
There are also single-circuit and double-circuit gas boilers. Single-circuit type is used only for heating the room different types, while fuel consumption will be quite high, practically no different from gas consumption during operation double-circuit boiler, which will also provide you with a constant hot water supply. Double-circuit boilers will be more economical since you will not need to buy additional hot water equipment Moreover, they are quite convenient to use.

Condensing boilers are used maximum amount thermal energy that is released when water vapor produced by exhaust gases condenses. This means that the exhaust gases have enough heat, which condensing boilers successfully use. The water entering the boiler will first be heated by the exhaust gases, but only then directly 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 experience the full taste of convenience autonomous system heating: possibilities self-regulation temperature regime Houses. 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 repair specialist is a person who will help you avoid such situations.

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

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

On this moment any master responsible for repairing Baxi or other gas boilers knows that the safety group consists of the following elements:

Attention! If any sensor fails, you can inhale carbon monoxide, which was “not noticed” by the system, will result in an explosion if the electrode does not work properly.

draft sensor with a plate rated at 75 degrees Celsius. This device monitors the condition of the boiler chimney, reacts to a failure in the removal of combustion products into the chimney, and their exit into smoke eliminators. As a result, it heats up and goes off, but it is best if, in addition to it, a gas alarm is purchased;
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 monitor the presence of flame. Quite often, the repair of Viessmann gas boilers begins with checking the electrode, since the work gas boiler without a flame it can even cause an explosion.
blast valve for pressure control. At a pressure above 3 bar, the system will force the boiler to release 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 boiler breakdown, 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, diversity and complexity automatic system control and management of the boiler do not always allow a person without experience to correct the operation of the boiler. Repairing Danko or Viesmann at the level of correcting the operation of the board also sometimes requires special equipment, something the owners simply cannot have.
Work and repair of gas boilers different manufacturers will vary, but generally electronic boards have a lot in common in principle. Repairing control boards of gas boilers is quite difficult for a novice technician, because experienced specialists can tell you some of their secrets about setting up boards.

Important Notes for Repairs

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

It is better to connect all sensors with “correct” data that are used in the operation of the boiler. And to avoid surges, use a voltage stabilizer for a gas boiler. The instructions for a particular boiler will indicate all the readings: as you connect the next sensor, you will be able to see where the system “sags”.

For example, if you need to check how voltage is supplied to gas valve, first, the board is tested taking into account the operation of the controllers. Then you should check the safety group sensors for broken contact. After this, the board is given a task to do: light the boiler. The pump is turned on sequentially, then it is controlled how the liquid or antifreeze circulates. When the turbine is turned on, you can see if there is a false flame. Only then can you apply voltage to the board. If the unit is not working properly, then the repair of Vaillant or Baxi gas boilers may not end there.

Training on repairing 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.

DIY gas boiler repair: is it worth it?
Modern gas boiler - a complex system, the main danger in case of malfunction is the use of explosive fuel or gas. To control the operation of a double-circuit or single-circuit heating unit, the boiler system includes automatic equipment that supports optimal performance. Therefore, 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 completely turn off the boiler, ventilate and leave the room by going to next room. Repair of baxi or other gas boilers must be carried out by a specialist, who must be called immediately.

If the combustion sensor or supply gas pipe breaks down, you need to turn off the device, let the boiler cool, turn off everything gas valves. Then you definitely need 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 everything off and wait for the technician: repair of Navien or Vaillant gas boilers is mandatory.

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

Do-it-yourself repair of a gas boiler can only be carried out if there is 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 houses. Gas boilers, like any heating equipment, require care and attention: place it in a dry and clean place, supply it with 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 one is that the room must be dry. Steel and cast iron parts of the boiler are subject to intense corrosion. So it is highly undesirable to organize laundries and dryers in the same room with the boiler.
The second condition for caring for a gas boiler is protecting it from dirt and dust. It is necessary to carry out dirty and dusty work at a considerable distance from the boiler, because the settled dust and dirt on the heat exchanger significantly reduces the efficiency.

Important condition- water quality. The water must 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 troubles 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 main reason corrosion.
The fourth condition is fuel quality. Do not buy boiler fuel of questionable quality, even if it is cheaper. Such savings can damage the boiler.

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

The owner must take care to check the condition of the chimneys and ventilation ducts. If it is necessary to 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 condition of the gas boiler, but also on the condition of the heating system as a whole, therefore it is recommended to: flush the heating and hot water supply system with special cleaning solutions in order to remove deposits from internal surfaces pipelines; eliminating leaks in 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 care. Regular cleaning of the burner will help avoid excessive fuel consumption and premature breakdown of the entire device. Take care and maintain your gas boiler. Caring for a gas boiler will allow the equipment to last for decades. Processed

For heating suburban or country house The Ferroli Zeus electric boiler is perfect. This heating equipment produces Italian company. Ferroli compares favorably with other manufacturers: equipment power, various small models, which operate on a 220V network, with efficient boilers that can heat 280 sq.m.

Features of Ferroli Zeus electric boilers

Ferroli Zeus electric boilers are manufactured with a power of 6 to 9 kW for heating a house with an area of ​​no more than 100 sq.m. For more large areas an electric boiler with a power of 12 to 28 kW is used.

Depending on the type of connection, Ferroli Zeus electric boilers can be:

• Single phase 220V. Up to 9 kW inclusive;
• Three-phase 380V. Over 12 kW.

Under the supervision of Italian specialists, Ferroli Zews electric boilers are manufactured at a factory in China. The barcode on the 693 equipment indicates these nuances. This assembly is a disadvantage of this equipment, since not everyone trusts the Chinese assembly. The cost of electric boilers is considerable, and if they were assembled in Italy, the amount would be enormous. Therefore, the Chinese assembly, to some extent, can be a positive thing.

Electrical and installation requirements

Heating equipment can only be adjusted under the supervision of a qualified specialist - an electrician, who may be authorized to work with a three-phase electrical network.

In order for the electric boiler to operate stably and without interruptions, it is necessary to take into account some recommendations:

1. If the electric boiler is connected to a voltage of 220V, then it must be connected through a separate machine. It should be highlighted in the shield.
2. In Ferroli Zeus electric boilers, the automation reacts poorly to voltage surges. Therefore, to increase the service life, you need to install an uninterruptible power supply.
3. Thanks to installed machines, grounding and RCD are provided safe work systems.

To connect to a three-phase power supply, you need to use a separate power cable. The instructions for use specify the cross-sectional standards and requirements for the wire.

Using an indirect heating boiler, DHW supply. Thermal energy during heating of water, which is necessary for the heating system, it is temporarily sent to the BKN. The rated output should be 10-15% greater than the output of a boiler with an electric boiler.

Design of Ferroli Zews electric boilers

Zeus electric boilers are single-circuit, that is, they are designed only for heating the house. But you can connect an external indirect heating boiler for hot water to the electric boiler.

The electric boiler is equipped with a built-in air and water temperature sensor. But in order to monitor and control the operation of the boiler depending on the temperature in the house, you need to purchase a separate remote room thermostat. In addition, you can connect weather-compensated automation. To do this, you need to install an outdoor temperature sensor. The electric boiler has a special connector for connecting such a sensor. With weather-compensating automation, you can save on energy costs.

The Ferroli electric boiler includes the following elements:

1. Electronic board.
2. Heat exchanger with heating elements made of copper.
3. Expansion membrane tank volume 10 l.
4. Safety valve.
5. Hydrogroup made of copper.
6. Circulation pump, which has three speeds, with an automatic air vent.

Using a large information LCD display, you can control the parameters of the heating system and water supply system:

1. System pressure.
2. Water temperature in the indirect heating boiler and in the heating circuit.
3. Electricity consumption.
4. If there are any faults, an error is displayed.

In addition to the information LCD display, the front panel of the electric boiler has built-in on/off buttons, a “winter-summer” function and a thermomanometer. The winter-summer function promotes energy consumption depending on the time of year. An electric boiler can operate in “warm floor” mode at the required temperature.

Advantages and disadvantages

The advantages of Ferroli Zeus electric boilers include the following:

1. Excellent quality of spare parts and components.
2. Large selection of models with different power.
3. Availability of an informative LCD display.
