We carry out heating from a ferroli gas boiler. Ferroli - gas boilers

The Italian company Ferroli is known primarily for its innovative developments in the manufacture of gas heating equipment. What is characteristic, each Ferroli gas boiler has a CE certificate, therefore, it meets all the norms and requirements stipulated by European standards. Employees of the company pay special attention to the improvement of products, as well as its regular updates.

Technical features of Ferolli boilers

Gas boilers from this manufacturer differ, first of all, in their reliability, innovative technological developments and adaptation to domestic operating conditions, which is why they are in great demand. Each model is equipped with a built-in digital type microprocessor control system. The compact heat exchanger, which is also part of the devices, is made of copper.

There is also an automatic adjustment of the permanent modulation of the flame. The surface of the combustion chamber and the heat exchanger is covered with a special anti-corrosion agent made on the basis of aluminum. The burner is equipped with a steel head ("stainless steel"). From the inside, the chamber is insulated with a special material, which is environmentally friendly, and therefore completely safe.

Note! Another feature of the Ferolli boilers is that they have a frost protection system and an anti-blocking pumping system for hot water and heating.

They are able to operate on both natural and liquefied gas. It is worth mentioning the ease of maintenance - all nodes of the system are located in such a way that they have free access. All boilers (and the vast majority of them are wall-mounted) are easy to install and operate. If desired, you can set up remote control of their work - for this you just need to connect the control panel.

How do Ferroli boilers differ from their competitors?

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

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

The Italian company Ferroli is on a par with the largest manufacturers of gas equipment. Mostly the designers of the company are guided by the needs of the average consumer, constantly releasing new models of their products. Today, Ferroli boilers can be found in various versions, each of them has its own set of excellent quality characteristics.

Peculiarities

To choose the right heating boiler from Ferroli, you can identify some of the main characteristics of its products.

You can divide the devices manufactured by the company into a number of categories:

• By location - designs from Ferroli are of 2 types. These are either floor or mounted products. Floor mounted ones are produced for large rooms, mounted ones are excellent for heating oversized spaces.
• In terms of the number of circuits, a double-circuit wall-mounted unit, as well as a floor-standing device, is perfectly suitable for heating the coolant itself and heating the liquid for domestic purposes.

• According to the principle of operation - devices with atmospheric-type flame burners are produced at a low price and maximum ease of maintenance, as they will work according to a simplified scheme. In units of a condensing type that have closed chambers, the air goes by force. Thus, they increase efficiency and reduce gas consumption. To use appliances with closed chambers of the furnace, electricity is indispensable.
• According to the material from which the heat exchanger is made. Steel appliances provide increased heat transfer. A cast iron boiler will have a low efficiency, but will last much longer.

Given the competition, the company's specialists offer more effective and popular solutions. As a result, Ferroli's gas-fired designs guarantee the right level of performance with little fuel consumption.

For consumers, it is especially important that the company produces models that can be adapted to work in difficult domestic conditions. Ferroli products will last 35-40 years even in harsh climates.

Ferroli differs from other companies producing boilers by the product control system using innovative microprocessors, and it is they who will control the level of flame burning in these devices. Also, the company's engineers invented a unique copper heat exchanger with compact parameters, which is coated with a special aluminum composition against corrosion.

Stylish design, simple maintenance and operation, ease of setup - all this is present in Ferroli products, for which customers appreciate them.

The wall-mounted gas boiler Ferroli Domina F24 E with a copper heat exchanger for heating and hot water, with electronic ignition and flame control is a new high-performance device, with a closed combustion chamber (all the air entering the heater is taken from outside the room), running on gaseous fuel.

The Ferroli Domina F24 E boiler is designed to produce hot water for heating and hot water supply. The unit uses advanced technological systems such as electronic regulation, control and safety devices.

A distinctive feature of the device is the built-in electronic device for ignition and combustion control, which ensures fully automatic and safe operation of the burner.

Differential air pressure sensor

The air differential pressure sensor is a safety device, it allows the burner to be ignited only after checking the operation of the fan.

If the difference between the pressure of the outgoing combustion products and the incoming air is not equal to the minimum calibration value of the sensor, then the sensor contacts will remain open and the gas valve will not open.

In addition, the electrical circuit of the boiler is designed in such a way that if the pressure sensor contacts remain closed when the fan stops, the burner will not start.

The principle of operation of the gas boiler Ferroli Domina F24

The Ferroli Domina boiler is suitable for operation on two types of combustible gas: methane or propane (liquefied gas).

The gas mode for operation is selected when ordering or changed at the installation site. The boiler works with advanced systems: electronic control, safety and control equipment.

When the room thermostat calls for heat, the pump and burner are switched on. With the help of an electronic flame modulation system, the boiler output is gradually changed until the set flow temperature is reached.

If the power required in the heating system is lower than the minimum power of the boiler, when the flow temperature exceeds the set value, the burner is switched off and the electronic system allows it to be switched on only after 2 minutes.

When the temperature set on the room thermostat is reached, the burner switches off and the circulation pump continues to operate for another 5 minutes to ensure better heat distribution in the system.

If during the heating phase hot water is drawn for the domestic hot water system, the electrical heating circuit is automatically switched off and the hot water circuit is switched on.

Throughout this stage, the circulation pump of the heating system stops, and the Ferroli Domina boiler supplies water at a set temperature.

The device maintains the water temperature of the water supply system constant, even when taking different quantities, by modulating the torch.

Every time the domestic hot water production ends, the heating pump starts for one second to prevent it from blocking, especially in summer.

Adjustment of Ferroli Domina boilers

Main burner pressure and flow adjustment

Wall-mounted gas boiler Ferroli Domina works on the principle of flame modulation. The system has two fixed pressures, minimum and maximum, which must be the same as indicated for each type of gas.

Adjusting the minimum pressure must be done first to ensure correct ignition of the burner. After that, the maximum pressure is adjusted. Any changes to the minimum pressure affect the maximum pressure value.

Minimum and maximum pressure adjustment with Honeywell V K4105G gas valve:

Connect a suitable pressure gauge to the pressure tap downstream of the gas valve.

Disconnect pressure compensator.

Remove protective cap.

Set the potentiometer (on the main panel) to the minimum value (counterclockwise).

Operate the Ferroli Domina boiler in heating mode.

Adjust the minimum pressure by turning the screw clockwise until the desired value is obtained.

Set the potentiometer (on the main panel) to the maximum value (clockwise).

Adjust the maximum pressure by turning the screw counterclockwise until the desired value is obtained.

Connect pressure compensator.

Replace the protective cap.

Adjustment of the maximum power of the heating system:

This adjustment is carried out only on the electronic board with the adjusting screw R3, starting from a system temperature below the maximum of the regulating thermostat (system temperature 50-60°C).

Connect a special pressure gauge to the pressure tap located in front of the gas valve; turn the temperature control screw to the maximum value, then set the desired pressure value.

At the end of this operation, turn on and off the Ferroli Domina boiler 2-3 times using the thermostat. At each start, check that the pressure corresponds to the set value and that the burner ignites correctly.

If necessary, make additional adjustments until the pressure stabilizes at the set value.

When igniting the burner, to control the set pressure, set the control thermostat knob to the maximum value, otherwise errors will occur.

Adjusting the temperature of the heating system and the room:

The water temperature of the heating system is regulated by turning the corresponding knob.

Turning the knob clockwise increases the temperature of the heating water, and turning it counterclockwise decreases it.

The temperature can vary from a minimum of 35°C to a maximum of 85°C. We recommend not to operate the Ferroli Domina boiler at a temperature lower than 45°.

The room temperature is controlled by setting the room thermostat knob to the desired value.

The thermostat automatically controls the boiler, temporarily cutting off the power line, depending on the heat demand of the room.
