Boilers from Ferroli

Wall and floor models

Despite a very wide range of installations for heating residential and industrial premises, the lion's share of Ferroli's profit is brought by gas heating boilers - wall and floor. At the same time, it is in the segment of wall-mounted household gas heating boilers 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 earlier the power required for heating could be provided only by large-sized installations, today, due to the use of modern technologies, even a small boiler can heat up to 300 square meters of living space.
• Ease of installation is another argument in favor of choosing small models mounted on the load-bearing wall of the room. Of course, it’s not worth installing the boiler with your own hands, since this requires a special permit - but the installation cost directly depends on its complexity!

The price also plays an important role. Although Ferroli products cannot be attributed to the cheapest price segment, you can still choose a very affordable option among mounted models.

Application and equipment

Ferroli boilers can be used in the following areas:

• Firstly, for heating private houses and cottages. As we pointed out above, the power quite allows.
• Secondly, the compact dimensions make it possible to use these installations even in apartment buildings for organizing individual heating.

For the effective implementation of these functions, Ferroli units are equipped with the following equipment:

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

Also included in the basic package is a unit responsible for modulating the flame and an ionization system for controlling the intensity of combustion. 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 instruction included with each product clearly demonstrates the process of connecting the boiler to the network, as well as the sequence of adjusting its main functions. The installation of Ferroli gas heating boilers should be carried out only by specialists, and no amateur performance!

Main series

DIVAtop

The list of models of heating equipment put on the market by Ferroli is very wide. Therefore, within the framework of 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 is high-performance double-circuit boilers for domestic use.

• DIVAtop devices are characterized by a stylish housing design, which allows them to be installed directly in residential areas.
• The key design feature of the DIVAtop range is the 3-way valve equipped with a separate servomotor.
• For efficient heat transfer, the heat exchanger for the hot water system, which has a lamellar design, is responsible.

DOMIcompact

Units from the DOMIcompact series are focused not so much on heating (although they perform this function quite efficiently), but on the fastest way to get hot water. At the same time, the heat exchanger of a special design installed in the boiler does not overheat, and scale is practically not formed in it.

• The DOMIcompact boiler can be controlled both with conventional adjustment knobs and with the help of 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.
• Also, this modification significantly reduced the percentage of emissions of harmful gases into the atmosphere.

Ecocept

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.
• Cermet burner with continuous modulation, equipped for the use of different types of gaseous fuels.
• Microprocessor-based boiler control system, adapted for the installation of a weather-compensated control system.
• Plate heat exchanger, providing the fastest possible heating of water in the hot water circuit.

At the same time, the Econcept series is characterized by a minimum amount of atmospheric emissions, as well as very impressive safety and fault tolerance indicators.

Usage Tips

In order for the boilers to break down less often, the user needs to take good care of the equipment casing by wiping it with a rag and soapy water. Once a year, a complete inspection of the product should be carried out. Experts advise to check the combustion process from time to time

It is extremely important to monitor the set parameters of Ferroli boilers

It is virtually impossible to find negative reviews about the equipment of this manufacturer.

All users note excellent performance, thoughtful design of devices and low gas consumption, almost silent operation of products, which is extremely important when installing them in residential buildings where boilers with heating and hot water are needed

But still, you can find certain nuances when using gas appliances from Ferroli. In reviews, the possibility of leakage in the heat exchange system is often noted. This is a common problem that can in no way be related to the quality of the company's products. Such phenomena appear due to improper use of the product and due to the use of hard water. For this reason, it is better to immediately choose models that are able to work with both gas and water.

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.
• According to 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.

Ferroli differs from other companies producing boilers by a 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.

Wall-mounted boilers are the most popular type of heating products, which are represented by such interesting models as "Diva" and "Divatop Domina". Due to its affordable cost and simple structure, the popular Arena model is in the greatest demand. This is a wall-mounted double-circuit type design, where there are also 2 heat exchangers. The combustion chamber here can be either open or closed. In the model, you can find parts from well-known companies (Siemens and Wilo).

Floor products represent the Pegasus and Atlas series in various models. Usually these are weighty devices, so they are mounted on the floor. The Pegasus model consists of a cast iron thermal device, a Honeywell valve, a reliable burner, a signal subspecies contact, and also includes connectors for high-quality connection of pumps and a small thermostat. For ease of use, ignition from the mains was provided and the possibility of connecting a boiler. The device has a built-in smoke removal control, an ionization sensor, a bimetallic indicator for monitoring overheating.These products have many options - a separate control unit, thermostat activation elements and turbo nozzles.

Condensing units from Ferroli can be found in the "Econcept" series, as well as "Energy" or "Bluehelix". These are designs with a single circuit, among them you can choose products with high power (the Econcept series, for example, will have the highest power - up to 300 kW). The characteristic features of condensing appliances include weather-dependent automation and a large LCD screen. In addition, an aluminum heat exchanger and a ceramic burner were built into the Econcept.
