Ferroli wall-mounted gas boiler: device, models (single-circuit, double-circuit, atmospheric), as well as setup instructions

Italian gas boilers Ferroli are products of one of the strongest European manufacturers.

The equipment manufactured by this company demonstrates high quality and stable operation; all components and parts of Ferroli gas boilers are assembled on the basis of advanced technologies and fully meet the most stringent technical requirements.

Each unit is equipped with an extensive self-diagnosis system, consisting of a network of sensors that are located on all critical components and parts of the boiler.

If any malfunction occurs or the unit leaves the set mode, the self-diagnosis system immediately reacts by notifying the user using an alphanumeric code on the boiler display.

Let's take a closer look at her work.

Main malfunctions of Ferroli gas boilers

The design of Ferroli boilers is distinguished by well-thought-out and high-quality elaboration of all components and parts.

However, any system has weak points, and gas boilers are no exception..

The operating conditions of some parts of the units are very complex; temperature loads contribute to the occurrence of fatigue of metals and other materials.

According to experts, the most common malfunctions include:

• The boiler does not turn on. There may be different reasons and ways to eliminate them, one of the most common problems.
• Blood pressure drops or rises. This is a serious problem that leads either to a coolant leak, which causes overheating and blocking of the boiler, or to excess pressure and blocking. Particularly dangerous is the increase in pressure, which can cause parts of the unit to burst.
• Fan or circulation pump failure. The loss of both functions means the system is unable to operate - the inability to remove smoke causes sudden overheating and blocking, and the lack of fluid movement has the same consequences, only detected by other sensors.
• Problems with the electronic control board. The cause of these problems is most often an unstable supply voltage or lack of quality grounding. The boiler electronics are very sensitive to any changes in operating mode. When drops or jumps appear, it begins to produce a continuous series of errors that do not repeat when restarted. Often, a static charge accumulates on the housing, which is transmitted through ground to the control board and ionization electrode, which causes error A02 to appear (the system sees a flame when there is none). The solution to the problem is to completely disconnect the boiler from the power system for some time and restore (or create) high-quality grounding.

In addition to those listed, there are a lot of problems with the combustion mode:

• Flame too small.
• Spontaneous start of combustion.
• There is no DHW heating.
• A sharp flash of flame with a pop.

All these problems are associated with deterioration in gas supply due to clogged injectors, failure of a thermocouple or fuel valve coil.

IMPORTANT!

The elimination of all problems should be entrusted to qualified technicians from the service center; repairing the boiler yourself may give the opposite result to what was expected.

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.

All main error codes and their interpretation and solution

Let's consider the main errors of Ferroli gas boilers and options for eliminating them:

Ferroli boiler errors are divided into critical (A) and non-critical (F). Those with the letter A lead to independent blocking of the boiler, but those with the letter F do not.

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.

Operating instructions - how to start correctly

The operation of Ferroli boilers does not differ in any specific actions or procedures.

The owner is only required to organize periodic maintenance, clean the body and interior of the boiler, and maintain the burner nozzles in proper order.

The procedure for starting the boiler is similar to the procedure for igniting other gas units.

A special feature is the need to maintain a pause between startup attempts, during which code D3 or D4 appears on the display (50 or 30 seconds).

The first code occurs after a critical error appears and the unit is blocked.

Until the required time interval has been met, a repeated restart is not possible.

The second code appears between attempts to start normally, if the previous one was unsuccessful.

This is usually due to air in the pump, piping or heat exchanger . Attempts are repeated until the air is removed from the boiler.

Price range

The cost of Ferroli wall-mounted boilers is in the range of 27-125 thousand rubles, depending on belonging to a particular series, specific model, power and other design features.

The difference in prices is quite large; the main factor in the increase in price is the type of heat transfer - traditional convection boilers are much cheaper than condensing boilers, although in Russia it is impossible to obtain a beneficial effect from them.

This point should be taken into account when choosing a boiler, so as not to overpay for unused functions.

IMPORTANT! The basic configuration of boilers requires additional costs for the purchase of a chimney, the conclusion of a warranty agreement and the purchase of other necessary accessories.

How to setup

The basic settings of the Ferroli boiler are carried out at the manufacturer . At the first start, additional adjustments are made to the parameters of all communications to ensure full compliance with the operating modes of the system and the supply of resources - gas, water, voltage.

The upper and lower limits of temperature and pressure of liquids, gas, and other important parameters are also determined.

Most actions are performed from the external control panel; the casing has to be opened only when carrying out complex repair work or to connect a room thermostat.

NOTE!

The setup must be carried out by a technician from the service center, otherwise the warranty agreement will become invalid or important components of the unit will fail due to improper operation.

What series and models are wall mounted?

Units intended for wall-mounted installation include boilers of the following series::

• Divabel. Double-circuit boilers with turbocharged burner. Produced in Belarus, the power of the units is 10, 13, 16, 18, 20 and 24 kW.
• Fortuna. Double-circuit boilers with atmospheric or turbocharged burner. The power range is between 10-40 kW, there are 8 models in total. They are produced in China specifically for use in Russia.
• Fortuna H. A series of wall-mounted single-circuit boilers with a capacity of 13, 24, 32 and 40 kW. There are options with atmospheric and closed combustion chambers. Made in China.
• Divaproject. Double-circuit boiler with a closed burner with a power of 24 kW. Manufactured in Italy.
• Divatech D. Double-circuit boilers with an open or closed combustion chamber. Power 24, 32 and 37 kW, manufactured in Italy.

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.

Floor standing atmospheric boilers

The floor-standing units manufactured by Ferroli are represented by a number of models, the most popular of which are Pegasus devices.

Cast iron gas boiler Ferroli PEGASUS 67 LN 2S

Let's look at their technical characteristics:

• the heat exchanger is made of cast iron, it is thermally insulated and shielded;
• if necessary, you can reconfigure the equipment to operate on liquefied gas;
• thanks to the built-in boiler, immediately after opening the tap you will receive hot water;
• it is possible to adjust the power;
• There is a self-diagnosis function; the liquid crystal display displays information about all faults in the form of coding. Due to this, maintenance is carried out in the shortest possible time; Ferroli boiler errors and their codes here
• there is a safety group, which includes a safety valve and two thermostats;
• a gas boiler can be combined with another heating device in one network. All stations will need to be controlled via a control board;
• If the consumer expresses a desire, the unit can additionally be equipped with a remote control and room temperature sensors.

Ferroli Pegasus floor-standing gas boilers have permission from Gosgortekhnadzor and a certificate of conformity that allows the installation of these devices for domestic and industrial purposes.

Why does blood pressure drop?

A drop in pressure in the boiler can be due to three reasons::

• The appearance of a leak in the heating circuit (including in the boiler itself). The peculiarity of this option is the constancy of the process, since the coolant will not stop leaving, no matter how much the system is recharged. In this case, you need to find the location of the leak. First of all, you need to check the condition of the drain tap or valve to see if it is open or damaged. If no problems are found in this unit, the entire heating circuit is checked sequentially. Sometimes they forget to close the drain valve on radiators, fistulas appear in pipelines, and connections fail. It is most difficult to detect a leak if the tap supplies a water-heated floor system embedded in a concrete screed. You can detect the problem by a wet spot on the floor or ceiling of the lower floor, and to do this you often have to remove the floor covering or suspended ceiling.
• Circulation pump failure. This problem is immediately detected by the self-diagnosis system, and it is easy to check the functionality of the pump. It is enough to carry out a visual inspection of the element and take appropriate measures.
• Expansion tank membrane rupture. In this case, the pressure will drop until the coolant fills the entire volume, after which the process will stop. Then an uncontrolled increase in pressure is possible, especially intense as the temperature of the heating agent increases. If it turns out that the problem element is the expansion tank, urgent measures must be taken to repair or replace the unit. Otherwise, with thermal expansion of the liquid, the heat exchanger or other element of the system will fail, which will require significant costs for repairs and restoration of the boiler’s functionality.

Main series

DIVAtop

The list of heating equipment models released to the market by Ferroli is very wide. Therefore, in this article we will consider only the most significant series from the entire product range.

The DIVAtop series is one of the first to be introduced to the Russian market. The basis of this series are high-performance double-circuit boilers for domestic use.

• DIVAtop devices are distinguished by a stylish body design, which allows them to be installed directly in residential premises.
• A key design feature of devices from the DIVAtop line is the presence of a three-way valve equipped with a separate servo drive.
• A heat exchanger for a hot water supply system, which has a plate design, is responsible for effective heat transfer.

DOMIcompact

Units from the DOMIcompact series are focused not so much on heating (although they perform this function quite effectively), but on obtaining hot water as quickly as possible. At the same time, the specially designed heat exchanger installed in the boiler does not overheat, and virtually no scale forms in it.

• The DOMIcompact boiler can be controlled using either conventional control knobs or a liquid crystal display. A built-in chimney can be used to remove combustion products.
• The DOMIcompact-B modification includes a more modern heat exchanger. Using the energy of steam condensation allows you to increase the power of the boiler, while reducing fuel consumption.
• This modification also significantly reduces the percentage of emissions of harmful gases into the atmosphere.

Econcept

The Econcept series represents the embodiment of the ecological paradigm. Distinctive features of the Econcept series boilers are:

• Heat exchanger-condenser made of high-strength aluminum.
• Ceramic burner with continuous modulation, equipped for the use of different types of gaseous fuels.
• Microprocessor control system for boiler operation, adapted for installing a weather-dependent control system.
• Plate heat exchanger that ensures the fastest heating of water in the hot water supply circuit.
