Overview of gas boilers Ferroli

An effective heating system is crucial for maintaining a warm and comfortable home. Due to their year-round dependability in providing hot water and heating, gas boilers are a popular option among homeowners. This article will examine gas boilers from Ferroli, a reputable brand in the heating sector, in more detail.

For more than 60 years, Ferroli has been producing heating products and has built a solid reputation for both quality and innovation. Their selection of gas boilers is made to be efficient and comfortable while satisfying the heating requirements of both residential and commercial buildings. Ferroli offers solutions to meet different needs, whether you’re looking to install a new heating system or replace an outdated boiler.

Ferroli gas boilers’ high efficiency is one of their main advantages; it lowers energy costs for homeowners while lowering their carbon footprint. These boilers are long-term economical and ecologically friendly because they are made to produce the most heat with the least amount of gas. Purchasing an efficient boiler is a wise financial and environmental decision, especially in light of the rising cost of energy and the escalating concerns regarding climate change.

The longevity and dependability of Ferroli gas boilers is another benefit. Ferroli boilers are designed with high-quality materials and components to ensure years of trouble-free operation.

About the manufacturer

The Ferroli Group, which has been producing indirect boilers, water heaters, and gas heating boilers since the 1950s, is the owner of the Ferroli brand. LLC "FerroliRus" is the official representative office in Russia. Products are also distributed through authorized dealers spread across nearly all regions of the country. The company has made a name for itself during its time operating within the Russian Federation as a producer of incredibly sophisticated and reasonably priced gas boilers that have serious technical features that are on par with those of more costly German and Japanese models. But over the past ten years, boiler dependability has fluctuated.

In actuality, all models—even the most inexpensive ones—have efficiencies between 91 and 93% and, as a result, some of the best gas consumption rates. For instance, the 24 kW Fortuna model’s maximum natural gas consumption is 2.72 m 3 /hour, which is equivalent to the well-known, cost-effective Baxi, Buderus, or Viessmann models. A robust, corrosion-resistant cast iron heat exchanger is included with all floor-standing models, while some wall-mounted models have a copper heat exchanger. Control is simple to use, and all models allow you to connect an external control.

The technology that preheats the secondary heat exchanger (DHW) in two-circuit models minimizes the delay in the hot water supply. Almost all modern boilers come with an extensive range of protective features, including auto-diagnostics, overheating and freezing protection, circulation pump stoppage, and more. Certain models are solar panel-compatible.

Wall-mounted models are popular, perform well, and are functional, but we do not advise choosing them. It is wise to consider if selecting floor-standing Ferroli is worthwhile. It’s all about dependability; specifically, a lot of issues with installation procedures and grievances on discussion boards, based on the quantity of gas service calls Ferroli is one of the top five foreign gas boiler brands in terms of unreliability.

There are many different types of faults, ranging from issues with ignition or water heating to malfunctions with the make-up tap, circulation pump, plastic elements, and even the heat exchanger during the first three to four years of operation (further information is available in the faults section below).

Furthermore, even identical models manufactured in the same year can function flawlessly for ten years while continuously breaking down in an adjacent home or apartment. Numerous factors are at play here, including the unsuccessful attempt to shift some model production to China (though the majority is still made in Italy), low-quality plastic, and high maintenance, cleaning, and coolant quality requirements.

The susceptibility of automation to erratic voltage in the home power grid is particularly important to note. One of the most frequent issues is the control board failing due to a power surge. For this reason, we always advise using a voltage stabilizer to connect any gas boiler with sophisticated automation.

Apart from a few instances of trouble-free operation lasting five or ten years, boilers are an easy-to-use device that is efficient due to modern technology. However, is it really worth the risk to purchase models—the amount of service calls we received today surprised us—when there are well-known brands like Baxi or slightly more expensive Lamborghini—not to mention the German or Japanese manufacturers—that can be had for nearly the same price?

It is sufficient to examine the forum discussions, obtain information from any service center, view search engine queries, or review the most common issues that we have highlighted at the end of the article.

The best and most famous models: characteristics and prices

Wall-mounted

Fortuna

The most popular model with two circuits. It stands out for its exceptionally high technical characteristics, efficiency, which varies with capacity and ranges from 92,4% to 93,1%, and the most common version’s maximum gas consumption of 2,72 m 3 per hour. The secondary heat exchanger (for DHW) is made of stainless steel, while the primary heat exchanger is composed of copper, which is more corrosion-resistant and thermally conductive. The previously discussed secondary heat exchanger preheating system is implemented in the boiler, greatly reducing the amount of time that passes before hot water is delivered.

Versions 10, 13, 16, 18, 20, 24, 32, and 40 kW are available. The most popular modifications are those with a closed combustion chamber (F), but open combustion chamber modifications (C) are also less expensive and somewhat less effective. Although they are only 5–10% less expensive, single-circuit versions such as Fortuna H are also available. Models for Fortuna are now made in China rather than Italy.

Domiproject

Outdated two-circuit model, no longer produced, but still obtainable in ample stock. Obsolescence has an appropriate, incredibly low price, which makes it in demand.

Its bithermal (dual) heat exchanger, slightly lower efficiency, and lower production costs set it apart from the Fortna. These features enable the boiler to be smaller in size, but they also pose significant cleaning challenges. If not, the construction is done as simply as possible using the least expensive materials, which naturally affects the final cost. available in versions with 24 and 32 kW.

Price range: 15,800–23,00 rubles.

BLUEHELIX K

One of the greatest and least problematic Ferroli gas boilers for heating a private residence, this condensing model is remarkable. According to the condensing principle of operation, there must be an additional heat exchanger present to store the heat from the condensate that is produced when combustion waste materials are burned. As a result, a large portion of the heat is now concentrated and directed toward heating the return heating line rather than just "flying into the pipe."

Efficiency: 109%; the heat exchanger is made of steel, but it is constructed using a unique technique that eliminates welding seams, meaning that it is durable both in theory and in actual use.

The primary distinction is the inclusion of a 50-liter built-in boiler within the body, which significantly improves hot water heating efficiency and user comfort. Exclusively made in Italy, only versions with 25 and 50 kW are offered.

Floor standing

Pegasus D

Single-circuit atmospheric gas boiler, practically problem-free against the background of wall-mounted Ferroli models. Features a cast iron heat exchanger, which is resistant to corrosion and therefore durable. It also has good efficiency indicators – 90,9-91,7% and simply excellent as for the atmospheric floor standing gas consumption, the maximum consumption of natural gas of the 23 kW version is 2,68 m 3 /hour.

The model includes every safety feature found on wall-mounted boilers, including safeguards against freezing, overheating, and pump blockages. The Pegasus D has an air vent, an air vent, and overheating protection. Pre-installed safety valves and air vents from the factory simplify boiler piping and reduce boiler installation time. It is possible to connect underfloor heating to an external control. The boiler weighs between 106 and 164 kg, which is relatively light in comparison to other cast iron equivalents. This helps to simplify the boiler room floor requirements. available in versions with 23, 32, and 45 kW.

Pegasus 2S

The identical atmospheric floor-standing boiler unit, but with a much larger capacity; it has a cast iron heat exchanger and is similar in design and technical aspects. With few competitors in its price range, it is ideal for heating large private homes and commercial spaces. It comes in versions with heat outputs of 56, 67, 77, 87, 97, and 107 kW.

In contrast, external controls can be connected to the new Pegasus D, which only had an air vent and overheating protection. Two-stage, auto-igniting burner. It is a fairly straightforward and unambiguous design overall.

Official site: where to see all models and operating instructions

The manufacturer’s official website in Russia is located at http://service.ferroli.ru/.

You can view the descriptions of all the models that are available by going to the "Equipment" → "Ferroli boilers" section. Electronic copies of comprehensive operation, installation, and setup manuals are attached to each model under the "Documentation" tab. The features, installation plan, operation switching and adjustment algorithm, maintenance features, and schematic images are all detailed in the manuals for each model.

What model of boiler in the end is better to choose

If you choose Ferroli boilers, the floor atmospheric Pegasus D is the best option in terms of "price-quality" ratio; it rarely requires service calls, typically lasts for five, seven, or ten years without experiencing any problems, and has fewer comparable models from other manufacturers at its price. The best option, if money is not an object, is to condense BLUEHELIX K with an integrated boiler.

The best option is to go with inexpensive wall-mounted models like Fortuna, Domiproject, etc.д., Despite their excellent technical qualities, we do not advise taking them into consideration due to the significant problems with nearly all of the modules.

Known faults of Ferroli boilers

The majority of the common flaws are built into low-cost wall-mounted models, but there are some others that are not completely problem-free.

Boilers must always be connected to the power grid via a voltage stabilizer since, in most cases, even tiny voltage fluctuations cause control boards (automation) to malfunction. A less painful but still common issue is the makeup tap breaking or leaking (it’s under the boiler and has a black painted handle); in Ferroli models, it’s just composed of rather flimsy plastic. Less frequently, circulation pumps, draught sensors, and heat exchangers leak after three, four, or six years of use.

It is worthwhile to thoroughly examine the most common operational issues, which are not always connected to the breakdown (click to expand):

If, upon turning on the hot water at the point of consumption, the water does not start to flow after ten to fifteen seconds, the heat exchanger that is clogged with limescale is probably the source of the issue. This is particularly common to models like Domiproject that have bithermal heat exchangers because their coil cross-sections are much smaller and can be blocked by even a thin layer of limescale. Although a complete replacement is usually required, the heat exchanger may occasionally still be flushed out. The flow sensor (flow meter) may malfunction far less frequently than the other source of the issue.

A leaky heating circuit, whether it be in the piping, safety valves, expansion tank, make-up valve, etc., is easily identified by a drop in pressure. The circulator is the most frequent component to fail. For the majority of Ferroli models, 1.2 bar should be the standard operating pressure. The boiler displays error F37 if the value drops below the critical threshold. The most frequent cause is a leaky expansion tank or make-up tap; to increase the pressure, you must inspect and seal every component of the system.

Every reason home gas boilers experience a drop in water pressure

There are two primary causes: a minor obstruction or malfunction of the ignition electrode, or a partial malfunction of the automatics (the board’s condition must be checked).

It is almost a given that the issue is with the control board, which failed as a result of a voltage drop. Ferroli needs to be connected through a stabilizer, which is something that practically all buyers overlook and makes it extremely vulnerable to the unstable domestic power grid.

Among the other well-known but uncommon issues are malfunctions related to the turbine, such as noise-producing or dead fans, as well as malfunctions involving the temperature and draught sensors.

The most frequent error codes

The burner did not light. See the above note regarding no ignition. An obstructed or flawed ignition electrode is most likely the root of the problem. It’s also important to pay attention to its connections and examine the state of the boiler’s wiring and control board.

After the turbine fan is turned on for 20 seconds, the air pressure switch is inoperative. In severe frosts, ice on the chimney headband is a common cause of the problem. It is easy to fix by carefully knocking it off. If the venting appears to be in good condition, the cause could be a misaligned diaphragm, inadequate contact on the air pressure switch (draught sensor), or a malfunctioning one.

The system’s water pressure is insufficient. happens when the system pressure falls below the 0.7–1 bar critical level. There are two possible reasons: depressurization (leakage) or insufficient coolant in the system. Leaks should be inspected in all heating circuit modules, including those found inside the boiler.
