Today we will look at the types of gas heaters from the Italian manufacturer Ferroli. Thus, there are two types of Ferroli boilers: wall-mounted and floor-mounted. Units that are suspended are also divided into two groups - conventional and condensing. The latter are characterized by high efficiency.
Wall-mounted gas boilers Ferroli
Wall heater from the Italian company Ferroli.
Ferrol wall-mounted boilers are available in different configurations and power, so you can choose a unit according to your requirements and budget. The first characteristic is the number of circuits. Thus, heaters can work not only to heat water in the heating system, but also simultaneously supply the house with hot water. Accordingly, single-circuit and double-circuit boilers are distinguished.
The second aspect is the type of combustion chamber and its configuration. The combustion chamber can be open or sealed. Open combustion chambers, just like a regular stove burner, burn out the air from the room (there is no fire without oxygen). Sealed chambers draw in air from the street through a special chimney called.
A heat exchanger (one or two) is installed in the combustion chamber. One heat exchanger (bithermic) is a pipe within a pipe into which pipes are embedded for separate smoke removal. The heat exchanger is made of copper. If there are two heat exchangers, then they are separated from each other. The primary one is made of copper, and the secondary one is made of stainless steel.
The richer the equipment, the more expensive it is to repair Ferroli gas boilers.
Complete set of Ferroli gas boilers according to the instructions:
- heat exchanger (one or two);
- gas valve – Siemens or HoneyWell;
- three-speed Wilo;
- smoke exhaust pipes – separate smoke removal system;
- Control block.
There are models with and without a liquid crystal display. The display shows information about the operating parameters of the heater and errors that occur during operation. The display lights up blue. The DivaTop 60 model is available with a built-in 6o liter boiler.
The efficiency of a Ferroli wall-mounted heating boiler of any model is approximately 93%. Minimum power 7.2 kW, maximum – 40 kW. The unit heats the coolant for high-temperature heating systems to 85 degrees, and water for hot water supply to 55 degrees. Boilers operate on natural and liquefied gas. The nominal energy consumption is indicated in the passport for each model. The gas inlet pressure must be at least 20 mbar for natural gas and 37 mbar for liquefied gas.
Ferroli floor heaters
The inflatable burner needs to be purchased separately.
Floor-standing cast iron boilers are available with a built-in or removable (inflatable) burner. First, let's look at models with a built-in burner. The equipment of the simplest boilers (up to 1 thousand Euros) is very modest:
- single stage burner;
- heat exchanger made of cast iron;
- gas valve HoneyWell or Sit;
- connectors for additional equipment (pump, thermostat).
Boilers priced from 1 thousand euros, in addition to the standard set, are equipped with a display, connectors for connecting a three-way valve, a boiler pump, outdoor temperature sensors, and boiler sensors. Thanks to this set of options, the heater can independently control the degree of heating of the coolant according to weather conditions. The equipment for each model is indicated in the operating instructions for the Ferroli boiler.
Units over 2 thousand Euro, for example Pegasus-DK, have a built-in 130-liter boiler and a 12-liter expansion tank, two pumps, and a magnesium anode installed in the boiler. A magnesium anode is needed to prevent the boiler tank from rusting. This is a consumable material; the anode must be changed periodically (as it breaks down). Heaters for 3 thousand Euros (Pegasus 2S and PegasusF3 N2S) have the same equipment as the cheapest models, with the exception of the burner - in expensive units it is two-stage. This allows you to expand the range of boiler power adjustment.
If any problems arise during the operation of the Ferroli gas boiler, a fault code is displayed on the liquid crystal display.
The peculiarity of boilers with a removable inflatable heating pad is that they can operate on both gas and diesel fuel, it depends on the type of burner:
- for gas – Sun M;
- for diesel - Sun G.
In the Atlas heater, instead of an external inflatable burner, you can connect an internal one or two-stage gas burner. In a rich configuration, for example, Atlas DK, there is a built-in 10-liter expansion tank and a 100- or 130-liter boiler, two pumps, and a liquid crystal display. The external inflatable burner is not included and is supplied separately.
Ferroli condensing boilers
All condensing boilers have a closed combustion chamber.
If you look through the operating instructions for the Ferroli gas boiler, you will see the following differences among the condensing units:
- number of heat exchangers – one or two;
- heat exchanger material – stainless steel or aluminum;
- burner material – ceramics or steel;
- presence of a boiler;
- presence of an air separator.
All heaters have a display, a bypass and a built-in modeling or three-speed circulation pump (except for the Energy Top W model - it does not have a pump). Condensing boilers have an efficiency of 109%. The minimum power is 2.1 kW, and the maximum is 79.5 kW. Prices range from 730 to 3000 Euros.
Gas boilers of the Ferroli brand have become particularly 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 the products of this brand reflect all consumer innovations 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 brand 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.
This review 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 among the smallest among analogues. Reviews of Ferroli gas boilers indicate primarily their compactness. The devices can be installed even in small kitchens, which is an undoubted advantage of these products.
The low-cost design of products from the Ferroli brand is manifested in the fact that the units of the Diva series are equipped with pressure control sensors - pressure switches - only optionally, like 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 of the transportation and installation conditions.
Analysis of some design solutions
Since the market for household gas boilers is quite densely populated, there is always the opportunity to compare the main operational parameters of competing boilers. In units from the Ferroli brand, the injection burner heads are made of AISI 304 stainless steel (for comparison, German-made boilers use AISI 310S steel).
Significant disadvantages of AISI 304 steel are its inability to withstand elevated temperatures for a long time, as well as insufficient mechanical strength. Let us present for comparison the chemical compositions of both steel grades listed above, precisely from the point of view of the required durability:
A comparison of the chemical composition clearly shows: 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. The data on heat resistance becomes even more expressive: if AISI 310S can withstand temperatures up to 1000 ° C for a long time, then AISI 304 short-term – up to 900°C, and long-term – up to 600°C.
There are similar questions regarding the selected heat exchanger material: Ferroli boilers use aluminum alloy, while similar products from Vissmann use cast iron. Although this circumstance slightly 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 heat exchangers made of copper, but their strength is inferior to cast iron. This solution may cause malfunctions of Ferroli gas boilers.
Burner type
Devices from the Ferroli brand 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 microcracks. Fan burners implemented in the designs of German gas boilers operate with constant water cooling, which:
- increases burner service life;
- reduces the emission of harmful gases into the atmosphere to European established environmental standards.
Of course, the operating instructions for Ferroli gas boilers are silent about these, as well as other design features of these units.
Unit capabilities
The instructions for Ferroli gas double-circuit boilers describe some features of the startup process, as well as the operation of control systems. Here are the operating instructions.
- To turn it on, you need to open the gas valve, then turn on the power supply.
- Place the knobs that regulate the temperature of heating and hot water in the desired position. After this, the boiler will automatically turn on when the room temperature drops or when hot water is needed.
- If you turn both knobs to 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 the event of a strong drop in ambient temperature. The signal lights do not light up.
- By adjusting the knobs, you can set summer or winter modes.
- There are three modes: Summer (only water heating for hot water supply), Winter (heating and hot water supply), and also a mode in which the hot water supply is turned off and only heating works.
It is worth knowing some of the nuances of starting a heating system. They are listed below.
- Possibility of working on any type of gas - liquefied and natural.
- Chimney freeze protection. At the same time, the instructions contain instructions on draining water from the corresponding circuits when the boiler is not operating in winter.
- Electronic ignition and a microprocessor control system for the operation of the boiler are truly useful technical innovations. Its implementation allows you to avoid unnecessary risks if the user of the heating unit is insufficiently qualified.
- Ferroli boilers are not equipped with shut-off valves, which increases the risk of flooding of the room if the pressure in the network is exceeded, when the unit is turned off, but the coolant supply does not stop.
- The process of installing adapters to chimneys is quite complex. The instructions and photos of Ferroli gas boilers show the replacement algorithm and sequence. But the complexity of the calculations requires calling a specialist licensed to work with these units, since some initial data are not provided in the instructions.
Typical faults
The above-described features also predetermine the malfunctions characteristic of the Ferroli gas double-circuit boiler. Among the most common breakdowns among people are the following.
- The Ferroli gas boiler does not turn on - this malfunction can occur due to a lack of gas in the network, the presence of air in the pipelines, a malfunction of the gas valve or ignition electrode.
- The water pressure in the Ferroli gas boiler drops. A malfunction of the circulation pump is the main reason. In the absence of a pressure switch (but with coolant in the system), such a malfunction may occur when the ignition power is insufficient, which should be increased. Damage to the electronic boiler control board is also possible.
Many reviews note the modern design and appearance of the products, which is generally typical for any Italian products. However, it is indicated that the products are not highly 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 service: existing specialized repair companies do not know the design of boilers well, and optional products for them (for example, a sensor for monitoring the connection of a boiler, etc.) are very difficult, if not impossible, to purchase.
The components of the circuit responsible for the operation of the water heater are especially unreliable: electronic boards often fail, the heat exchanger is unstable, and you have to use a gas tap to regulate the water temperature. At the same time, prices for Ferroli double-circuit gas boilers depend on their power and start from 30,000 rubles.
Ferroli F24 DOMIproject
The ferroli boiler has a modern design. Produced using modern technologies, it differs from others in workmanship and reliability. This is a high-efficiency thermal gas generator, manufactured for heating, and runs on both natural and oil gas. Produces hot water.
The boiler body has a copper plate heat exchanger. It provides excellent heat transfer regardless of operating conditions. The housing also includes an electronic burner, which is ignited electrically, and an ionization system that controls the flame.
The operation of the boiler is automated using microprocessor control and monitoring of the diagnostic system. To supply hot water, the DHW system is regulated automatically and without interruption.
To obtain the desired room temperature and hot water temperature, these parameters must be adjusted automatically. The boiler operates year-round with a regulating system and control.
The boiler has a display that provides all the information about the operation of the unit. Malfunctions are shown on the display and can be automatically corrected.
Control Panel
The control panel has a button with many functions, two knobs, a display on which there are three lights: green, yellow, red. With their help, information about the operation of the ferroli is displayed. The lights indicate a fault code, which in most cases will restart automatically.
Enable and disable
Using the instructions, it is possible to familiarize yourself with how the gas unit starts and turns off. The gas valve located in front of the boiler must be opened. The air that is in the gas pipes must come out. After which the ferroli is connected to the network, and the control knobs are set to a specific heating or hot water mode. After a certain request, the ferroli will begin its work. To turn off, turn the knobs to the minimum position. In this case, the electronic board is not disconnected from the voltage. The frost protection system is active. It stops functioning if the power supply is disconnected. 
Using the remote control instruction, the system temperature will be at a certain level and controlled by the room thermostat.
The heating system temperature can be from 30°C to 85°C. But operating ferroli at temperatures below 45° C is not recommended.
The hot water temperature can vary from 40°C to 55°C. By turning the knob, the desired temperature is set. When a remote control is connected, the hot water is adjusted from the remote control.
ECO/COMFORT setting mode
Ferroli has a special device that produces high-speed sanitary water. In this mode, hot sanitary water is supplied to the hot water supply system without delay.
Maintenance
The ferroli boiler must be regularly maintained. At least once a year. To clean the boiler, use a damp soft cloth and soapy water. Detergents and solvents are not recommended.
Installation
A gas boiler must be installed by professionals who follow the instructions. The water in the boiler is heated to boiling temperature, and it is connected to the heating system.
A gas boiler has an open combustion chamber. Installation and operation are carried out in well-ventilated areas, which must comply with UNI-CIG 7129 standards. Considering that the boiler power does not have 34.8 kW, its installation is permitted in any well-ventilated area. The unit is hung on the wall.
Connection types
For excellent functioning and long service life, the hydraulic system of the boiler must be sized to comply with the standards of the instructions, and ensure proper operation and continuous flow of water.
To connect the gas connections, the gas pipes must be cleaned. Connection takes place strictly in accordance with current standards.
In addition, the boiler has an electrical connection, which requires proper connection to the ground loop.
The boiler must be commissioned by highly qualified specialists.
Do you use Ferroli gas equipment? Then our article will be useful to you. All possible malfunctions and errors in the operation of the Ferroli boiler are discussed here. Whatever problem arises - the equipment does not turn on, the pressure drops, there is no hot water - the recommendations in the table will help you find a solution.
Design and features of Ferroli boilers
Ferroli brand gas boilers can be installed in any home, even if the mains are not connected. The equipment is connected to a common pipeline or a separate cylinder with liquefied gas.
Flame modulation allows the heat exchanger to be heated evenly. It is made of copper, so the efficiency is 92%. Anti-corrosion coating extends the service life of the device. The ignition block is also covered with aluminum.
The most popular among users are the double-circuit models “Domina”, “Diva”, “Domiproject”, “Pegasus”.
Error codes and malfunctions
Errors can be displayed on the boiler display or on the control panel. Codes are divided into several categories:
- Critical - "A". When they occur, the system is completely blocked and the equipment does not start. To eliminate it, you need to exclude the cause of the appearance of symbols on the screen and restart with the “Reset” key. The reboot will not occur immediately, but after 30 seconds after pressing the button;
- Non-critical - "F". Minor problems that require user intervention and system adjustment;
- Pauses - "D". These symbols indicate the intervals between certain modes.

| F50 | Problems with gas fittings. |
|
| fh | The circulation pump is removing air. After three minutes the code will disappear. |
There are others too problems that are not indicated by codes and not described in the instructions:
- Small flame in the burner. Adjusting the pressure on the burner, it is necessary to clean the nozzles from dust and dirt;
- The burner starts randomly. The injector needs cleaning, the broken thermocouple is being replaced. The fuel valve coil is checked for breaks;
- Hot water does not heat up. Reduced pressure in the line. It is necessary to adjust the power and clean the heat exchanger from scale;
- The flame flares up sharply. Cleaning the combustion chamber and burner. Checking traction.
Most errors block the operation of the boiler. Even if after a restart it functions again, you should not let the problem take its course. You need to find out the reasons for its occurrence and contact a specialist or solve the problem yourself. Regular maintenance prevents problems and prevents contamination of equipment parts.
