Wall-mounted gas boiler IMMERGAS. Model overview

Gas boilers IMMERGAS – two hundred heating horses, says the company slogan.
The company located its production facilities in Italy and over 50 years they have gained trust, respect, and recognition of quality, predetermining exclusively positive feedback from their consumers. The north of Italy has long been famous for technical innovation in all areas of industrial production. The largest company on the European market, specializing in the production of wall-mounted gas boilers under the world-famous Immergas brand, was no exception.

Using only the latest technologies and modern design in its developments, the Immergaz gas boiler is distinguished by its reliability and high quality. The company is so confident in its products that it provides an unprecedented extended warranty of 5 years!

By offering the Immergaz gas boiler to the modern heating market, the company took care of expanding the range of equipment so that the boilers can be used not only in residential buildings, but also in industrial facilities, offering mini boiler rooms for large areas.

Our review is devoted to wall-mounted modifications of boilers called NIKE STAR 24 3 R, NIKE MYTHOS 24 3R, and EOLO STAR 24 3R - which have become bestsellers on the domestic market. Let's consider their features, principles of operation, technical characteristics. Let’s try to create our own opinion about the advantages of the engineering solutions of Immergaz specialists, talk and leave feedback on possible disadvantages.

Neutral reviews

Advantages:

works well so far

Flaws:

broke down, then at least we were crying without heat for a week until the repairman arrived

A comment:

The boiler worked for 5 years and the control board burned out; the board costs 100 USD without warranty. and work 50 b.r. new, but the warranty on the new board is only half a year, which is very upsetting. Another big minus is that no one undertakes to repair this boiler except for one single monopolist company and the local gas networks (whose professionalism is doubtful).

repair is problematic

Advantages:

silent

Flaws:

consumes gas excessively, heats water unevenly

Thunderstorm, power surge (there is a stabilizer) and repairs for 11 thousand rubles. The master said the board is burning out... all over Vladikavkaz... Just a holiday for the “Giraffe”... it’s never possible to swim at a normal pace. the water is either boiling water or cold... (especially pleasing when you are in foam) The pressure drops constantly... I almost didn’t follow it... cold...

User manual

Beretta boilers are operated automatically, which does not require constant human intervention.

The user is only required to adjust the heating mode according to his own feelings, switch the boiler to winter or summer mode (turning off or starting the heating circuit), maintaining the cleanliness of the body and periodic maintenance (by service workers).

All serious problems can only be solved by calling a specialist - eliminating constantly occurring errors or incomprehensible phenomena that occur with the boiler in operating mode.

In addition, the user independently fills the system with water (or recharges as necessary).

The process consists of supplying liquid through the make-up tap and filling the system until the water pressure reaches 1-1.5 Bar. This is below the operating pressure, but when heated, the water will expand and due to the increase in volume, the pressure will reach the desired value.

The boiler starts automatically when the required temperature of the coolant in the system is set.

It is prohibited to pour water into a hot boiler due to the risk of destroying the heat exchanger. It is necessary to wait until the boiler cools down and only then add water.

Specifications

Let's consider the technical parameters of gas units from Immergas:

Classification

Gas boilers for heating private houses Immergas are divided into double-circuit and single-circuit. The design of such models includes a built-in piping with safety valves, circulation pumps and expansion tanks. Some gas boilers are equipped with built-in tanks for storing heated water. Some Immergaz gas double-circuit boilers are equipped with a unique system that regulates the pump rotation speed through frequency modulation, which reduces gas consumption for the heating system.

Condensing models of Immergaz boilers are divided into two types - floor-mounted and wall-mounted. The devices are characterized by a high level of efficiency and a 10-15% reduction in heating costs. All boilers are included in five model lines.

A wide range of gas boilers for heating a private home from the Immergas brand is presented in models equipped with different heat exchangers - classic copper, cast iron and stainless steel. The ARES series is equipped with cast iron heat exchangers.

Immergaz gas boilers are also equipped with:

• Automation that regulates the microclimate in the room depending on the ambient temperature.
• Independent heating circuits.
• Superior automatic system, facilitating boiler control.
• Heat exchangers of increased volume, resistant to clogging.
• Remote control systems.

Flue gases are removed naturally through classic chimneys or forced through coaxial chimneys.

In the review of Immergaz gas boilers, it is worth noting that the company’s products are fully adapted to Russian operating conditions and remain operational when the pressure of water and gas changes.

Features of the brand and product range

The assembly of Immergaz wall-mounted gas boilers takes place at several factories: the main production is located in Italian territory, and additional production is in Slovakia, where the equipment is assembled. Information about this can be read on the manufacturer’s official website.

Now in Western European countries it is allowed to install only condensing units, so many companies, because of this feature, have transferred the production of their own traditional boilers to Slovakia.

The Russian market offers the following devices of this brand:

• condensation;
• classic.

The first type of boilers was not widespread among Russian buyers due to its own high cost and cheap gas in our country. Because, as you know, the main advantage of condensing units lies precisely in saving natural gas by 20-30%, and in European territory it is much more expensive than in Russia. Therefore, in our case, it is better to consider classic Immergas gas boilers, which are divided into:

• units with one circuit (for heating only);
• with two circuits (heating and hot water heating);
• with one circuit + built-in boiler for 45 or 60 liters.

Single-circuit gas boilers of the Eolo Mini X 3E and Nike Mini X 3E lines are intended only for equipping rooms with heat, but their price is not much lower than for 2-circuit ones, which is why Immergaz double-circuit gas boilers, which combine advantages of a heating boiler and heating column. All models with one circuit can be connected to an indirect heating boiler to heat water for domestic needs.

Gas boiler IMMERGAS EOLO STAR 24 4E

The manufacturer's equipment is also produced:

1. With a closed combustion chamber (turbine units with forced ventilation).
2. With an open type chamber (natural draft).

The Immergas gas boiler with a closed combustion chamber “Eolo” is produced in the following options:

• “Mini” line with two heat exchangers for heating and preheating liquids;
• “Star” line only with a bithermic heat exchanger for two circuits.

Units with an open combustion chamber are produced with the “Nike” marking:

• “Mini” 24 E series with a pair of separate heat exchangers and a power of 24 kW;
• “Star” 24 3R series with a biothermal copper heat exchanger and the same power characteristics.

All double-circuit wall-mounted gas boilers Immergaz can be modified. To operate on bottled gas, you need to install special nozzles (purchased separately).

It would also be fair to mention the floor-standing units of the Hercules series from the Italian manufacturer. The model has a condensing module for greater performance (maximum 32 kW). However, the boiler is characterized by economical fuel consumption, so the equipment will pay for itself to the owner within 2-3 heating seasons. If desired, additionally purchased:

• indirect heating storage boiler;
• room thermostats, sensors that read the temperature in the atmosphere and adjust the operation of the unit accordingly.

The boiler does not turn on - there is no indication

Almost all modern gas boilers are equipped with a control board and an information panel with a liquid crystal display or LED indicators. If there is no indication, first of all you need to make sure that power is supplied to the boiler. Typically, the electrical connection of the boiler is carried out through a separate “automatic machine” - check whether it is turned on or not.

The surest way to make sure that power is supplied to the boiler is to check with a multimeter in voltmeter mode the presence of 220V at the connection point to the boiler board. If there is no voltage, it is necessary to localize and eliminate the problem. In real life, it happens that someone in the household simply pulls the plug from the socket.

Safety fuses

It is also worth paying attention to the location of the fuses. In some boilers, depending on the model (for example, Ariston, Buderus, Vaillant), the fuses are located on the board itself, and in some, before they are connected to the board

If there are no problems with the electrical connection to the boiler, you should check the integrity of the fuses (with the same multitester in the “continuity” mode).

If the fuses are intact and there is 220 volts at the control points, it is likely that the boiler does not turn on due to a malfunction of the control electronics.

If during the inspection it turns out that the fuses have blown, then there was at least a problem with the power supply. In this case, it would be correct to first conduct research on the actuators (fan, pump, priority valve) and boiler wiring for a short circuit. However, in practice, even representatives of specialized organizations simply replace the fuses with good ones and check the boiler in operation. If the fuses blow again, then sequentially turn off the high-voltage parts of the boiler to identify the problem area (this is not a recommendation for action! This approach is not entirely correct).

Several spare fuses are usually supplied with the boiler.

If the fuses blow due to damage to one of the actuators, it must be replaced (or the cause of the short circuit must be eliminated). In the case where it is proven that the mechanisms (and wiring) are in good working order, the control board itself remains. Blown fuses indicate that there was an unacceptable load on the electronics (thunderstorm, pulsed power surge in the network), so the cause of the malfunction may also be a short circuit on the board itself.

Water (moisture) getting on the board

Water ingress is one of the most unpleasant situations. Although the board is in a protective case, water may get inside due to leakage or condensation. Often it gets into the box through the wires. Water ingress almost always causes damage to the board, in most cases irreparable. Characteristic stains and oxidation will be visible on the board due to water.

Varistor and power supply

Often, if the boiler board is damaged, burnt or charred elements can be visually detected on it. A varistor is a protective element of the board that is installed at the input of the circuit. In most cases, this is a blue round part (but not necessarily). When the rated load is exceeded, the varistor is destroyed and opens the circuit. In some cases, if the varistor helped prevent damage to the electronics, it is enough to bite it out to eliminate the gap in the circuit

Important! Although the board circuit will work without a varistor, it should be remembered that the varistor is a protective device and the correct solution would be to replace it. The power supply is a microcircuit that is also damaged primarily during pulsed power surges or during a thunderstorm

If cracks or damage are visible, the boiler board will likely need to be diagnosed and repaired.

Display board

For some boiler models (Vaillant, Ariston, Navien), the control unit consists of a main board and an information board (display board). The boiler may also not turn on if the display board is broken. The display board, unlike the main one, is cheaper, but most often cannot be repaired. In this case, the fault can only be identified by replacing a known good part.

If the gas boiler is working, there is an indication on the display, but it does not start or produces errors, further diagnostics are required.

Reviews of Immergas Eolo Mythos 24 2

Write a reviewEduard, 03/11/2021

Advantages: There are no advantages.

Disadvantages: After four years of operation, I replaced the heat exchanger and now I will have to change the board.

Comment: The boiler is very bad. Don't mess around.

Nikolay Bolotov, 10/24/2020

Pros: Reliable and quiet

Disadvantages: a little expensive

Comment: I bought it on the advice of friends after a Korean boiler that kept breaking down. For 5 years it has never caused any problems, and it has never been serviced. Makes water comfortable. When I bought it, it seemed a little expensive compared to the Korean one. But as it turned out in the end, it was worth it.

Stas Sotnikov, 10.15.2020

Pros: Reliable and very quiet

Disadvantages: none found

Comment: Makes water comfortably, without jumps. It works very quietly, installed in the kitchen, no louder than a refrigerator. It works in tandem with a room thermostat, operation at room temperature is very comfortable. Simple control of the boiler itself, everything is intuitive, made for people. The longest warranty of all the boilers I have found is 3 years.

Tolobistyuk Dima, 10/01/2017

Pros: Not good yet, but it works.

Disadvantages: It leaks air through the nipple.

Comment: I bought an apartment in a new building with this boiler. After a year, he refused to heat hot water. I called the developer, who contacted the supplier. The supplier said that I had not undergone annual maintenance and sent me away with the guarantee. I was not warned about maintenance when handing over the apartment. In short, I had to figure it out myself. It turned out to be a bad electrical contact on the 3-way valve. It also leaks air through the nipple of the expansion tank. You have to constantly pump it up. The nipple does not unscrew at all. There was also a constant overheating error. I had to adjust the gas regulator several times. I don’t know why this was not configured initially or why this setting gets lost. In short, if you want to constantly tweak and finish something, then this boiler is for you.

Alexander Egorov, 11/29/2016

Pros: I can't highlight anything.

Disadvantages: Flame modulation for heating does not work.

Comment: Flame modulation on heating does not work. When turned on, the beginning of one sign lights up, then the second, the third blinks immediately goes out and continues to work on the second icon. When the temperature rises, the flame does not decrease until it turns off. What I also didn’t like was that all the pipes were mixed, not like on other boilers. When replacing the boiler, all the pipes had to be redone. In short, I don’t recommend it to anyone.

Brief information about the design of the heating system

Modern gas heating systems are complex systems. Their operation is monitored using a whole range of automatic devices, which you need to become familiar with before you begin repairing gas boilers yourself.

Basic elements of a security group:

• Draft sensors designed for 75 0 C. This device makes it possible to monitor the condition of the chimney. If normal smoke removal fails, the temperature rises and the sensor is triggered. Optimally, in addition to the traction sensor, a gas alarm is purchased.
• The monostat protects turbocharged gas units from poor removal of combustion products due to a clogged chimney or heat exchanger.
• The limit thermostat is designed to control the temperature of the coolant in a heating installation. When the water boils, the overheating sensor turns off the device.
• The flame control electrode, when detecting its absence, turns off the operation of the heating unit.
• The blast valve serves to control the pressure. When the pressure rises above a critical value, excess coolant is discharged in batches.

Problem solving

Let's look at ways to solve the most common problems:

• 01. This error was discussed above and is a consequence of gas supply failures or incorrect power connections.
• 03. Problem with the smoke exhaust sensor or thermostat. Check the functionality and connection; in difficult cases, replace the sensor.
• 04. Lack of standard load resistance at the terminals. Clean the contacts and check the connecting wires.
• 10. The heating circuit pressure has dropped. The error indicates a lack of coolant, the need to replenish the system and eliminate leaks.
• 11. Problems with the smoke pressure thermostat. Check the operation of the fan or the condition of the chimney.
• 27. Low circulation rate. The condition of the circulation pump should be checked. Particular attention should be paid to the impeller blades, which are made of plastic and can fail.
• 28. Leakage in the DHW circuit. Check the taps, connections, inspect the water taps - perhaps a tap has been left open somewhere. You should also pay attention to kitchen or plumbing fixtures connected to the hot water supply - perhaps the cause of the leak lies there.
• 31. Incompatibility or failure of the electronic control board. The culprit here could be a software failure that requires re-flashing the board, or a purely mechanical failure, burnout of microcircuits due to a power surge, etc. Replacing the control board is an expensive procedure, so you should protect it as much as possible from external influences (install a voltage stabilizer).

IMPORTANT!

Some errors appear randomly due to voltage fluctuations. Strong fluctuations cause a series of errors on the display, which almost never repeat. To avoid such situations, you should immediately connect a power stabilizer (or better yet, an uninterruptible power supply).

Why does the pressure in the boiler drop?

The main reason for the pressure drop is coolant leakage.

Various reasons may be involved here:

• The boiler drain valve or one of the system radiators is open. If this happens, the coolant is constantly removed from the system, which causes a drop in pressure. The solution to the problem is obvious - close the tap, or repair it.
• A leak has appeared and the coolant is leaking into it. This case is much more difficult, since the leak cannot be detected immediately. Sometimes it is found only by wet spots on the floor or ceiling of neighbors. A detected leak is immediately eliminated by replacing the pipeline or the problematic radiator.
• Failure of the expansion tank membrane. In such a situation, the pressure drop continues only until the entire volume of the tank is completely filled with liquid. After this, the pressure stabilizes for a short time and then begins to increase to a critical value. These signs are usually used to identify the problem. The solution is to replace the expansion tank (or repair it if possible).

history of the company

The company began its existence in 1964. In 1965, the company developed and produced its first gas boiler. Since 1967, having received the first patent, the Immergas company begins to gradually develop and expand. Here are the company's main milestones:

• Since the mid-70s, the company has focused on the production of household units for heating residential premises. The first model with a built-in water heater tank goes on sale.
• In the 80s, a wall-mounted model of a boiler with a boiler was developed and produced.
• Since 1994, the Immergas brand entered the world market, where it successfully gained a foothold. All over the world, Immergas wall-mounted boilers have positive consumer reviews.

• In 2000, the company relied on innovative energy-saving technologies and developed condensing heating equipment. Such equipment is very environmentally friendly and economical.
• Following the development and introduction of condensing boilers, Immergas focused its potential on hybrid systems capable of supporting a complete cycle of cooling, heating and hot water production for an entire house.

How to clean the heat exchanger

Beretta boilers are equipped with either separate or bithermal (combined) heat exchangers. In the first case, flushing gives a greater effect; the second type of heat exchangers is difficult to flush due to the design features.

There are two washing methods:

• Mechanical. Requires disconnecting the heat exchanger from the boiler. The results of such washing are not particularly successful, since it is extremely difficult to clean the internal surfaces mechanically.
• Chemical. Does not require dismantling the heat exchanger, but is done using a special device. It has a fairly high efficiency, is able to eliminate scale and extend the service life of the unit.

For washing, special reagents are used to dissolve scale and remove it from the internal cavity of the heat exchanger tubes. The procedure should be performed every 2-3 years, depending on the quality of the water. To carry out the work, you must invite a specialist from the service center.

Repair and operation

Many modifications of boilers have an LCD screen; error codes are always displayed on it if they occur. The codes can be quickly deciphered by simply looking at the instructions included with the specific gas unit.

Fault code 16, which means the fan does not turn on, indicates that the circuit is open. To do the repair yourself, you need to diagnose the fan, subsequently repair the circuit, and routinely tighten the contacts, and then all problems with the boiler will be solved.

To do this, press the Reset key. This happens after a long period of equipment downtime. All that remains is to bleed excess air from the system and restart the ignition.

If you need to switch your boiler to summer mode, then press the button with the image of an umbrella and set the most comfortable temperature for yourself. If it suddenly becomes cool and there is a need for heating, then simply turn on the winter mode - the icon with a snowman. And also select the desired coolant temperature.

Video review of the Immergas gas boiler, see the following video.

Settings

“Navien” is programmed for winter (heating and DHW) and summer (DHW) operating modes - with the “Snowflake” and “Sun” icons. The network temperature is adjusted on the LCD remote control when the “radiator” icon on it is lit. In some options, the “Heating Mode” is started, in others the knob is turned. A flashing LED records the set water temperature.

If the icon just lights up without pulsating, the actual temperature in the network is displayed. By selecting the icon, use “+” or “-” to increase or decrease the temperature. After a couple of seconds the LED will stop flashing and show the actual temperature. They regulate the heating temperature from 40.0 C to 80.0 C. If it is set incorrectly, an error code will be displayed.

Note! The DHW temperature is adjusted in the same way, only on the remote control there are pictograms with a tap, the range is from +30 to +60 C.

And more about malfunctions

Most modern gas boilers are equipped with a diagnostic system that independently detects any malfunction and displays its code on a digital display. This is a good hint for the owner. The boiler kit usually comes with instructions that explain the error codes. If I look into it, the owner will quickly understand what the problem is and also determine possible ways to eliminate it.

Different models have differences in diagnosing breakdowns; for example, a Supermaster gas boiler indicates possible faults by flashing a red light. Judging by reviews from owners, each modification has its own set of common problems. For a Weiland gas boiler, possible malfunctions are mainly as follows: lack of water, the unit does not start, the burner flame goes out, there is not enough water pressure.

You should always remember that preventing a breakdown is better than repairing it. You shouldn’t wait for the boiler to fail at the most inopportune moment. It is better to prevent this: clean and change filters in a timely manner, check the draft in the chimney, make adjustments according to the instructions, and promptly eliminate minor faults.

Features of boilers from the Immergaz company

Immergaz boilers are available for sale in many models. Among them there are single-circuit and double-circuit samples, devices of condensation or convection type, as well as floor- and wall-mounted devices. In total there are over 10 series, differing in characteristics, type of installation and principle of operation. Each series includes models of varying power and performance.

• According to the standard double-circuit scheme without a boiler;
• According to the scheme with a built-in boiler;
• According to the diagram with the connection of an external water heater.

Models with built-in storage boilers hold up to 120 liters of hot water. Some samples with a standard design use Aqua Celeris technology. It provides instant supply of hot water when the tap is opened.

Gas boilers from Immergaz are divided into single-circuit and double-circuit. They include built-in piping - there are circulation pumps, safety valves and expansion tanks on board. Some models are complemented by built-in hot water storage tanks. As for pumps, some boilers have a unique system for regulating the rotation speed through frequency modulation. This reduces gas consumption for the heating system.

In the gas boiler segment from the Immergaz company, condensing type models are presented. They can be floor or wall mounted. The devices have increased efficiency and reduce heating costs by up to 10-15%. All of them are divided into five lines - Victrix Tera, Victrix PRO, Victrix TT and Victrix Superior (wall-mounted), as well as Hercules Condensing (floor-mounted).

The wide range of Immergaz boilers includes models with different types of heat exchangers - traditional copper, stainless steel and cast iron (including separate and bithermic). Cast iron heat exchangers are presented in the ARES series. The power of boilers from this line is up to 60 kW. If we talk about the most powerful units, we will find them in the Victrix PRO series - their power varies from 35 to 120 kW.

Also found in Immergas gas boilers are:

• Weather-dependent automation – controls the climate in the house depending on the outside air temperature;
• Independent heating circuits - in high power models;
• Superior automation – makes it easier to control gas boilers;
• Heat exchangers of increased volume - they are resistant to clogging;
• Remote control systems.

Flue gases are removed forcibly through coaxial chimneys or naturally through traditional chimneys.

Full-time education

Training takes place in regional offices throughout Russia under the guidance of practicing teachers

The task of the organization, in particular the beginning of the daily work of forming a position, largely determines the creation of forms of development. The significance of these problems is so obvious that the new model of organizational activity requires the identification and clarification of further directions of development:

• simple adjustment of equipment operation for any heating system, for example, by adjusting the burner re-ignition delay;
• maintaining a set temperature using weather-dependent automation (most models) and a control panel (all Immergas series);
• operation in DHW mode with minimal water consumption, as a result of which its temperature remains relatively stable, regardless of consumption;

The implementation of the planned targets makes it possible to assess the significance of the positions taken by the participants in relation to the assigned tasks. We should not, however, forget that constant information and propaganda support of our activities largely determines the creation of further areas of development. The significance of these problems is so obvious that the strengthening and development of the structure represents an interesting experiment in testing the forms of development.

Wall-mounted gas boiler IMMERGAS. Model overview

Gas boilers IMMERGAS – two hundred heating horses, says the company slogan. The company located its production facilities in Italy and over 50 years they have gained trust, respect, and recognition of quality, predetermining exclusively positive feedback from their consumers.

The north of Italy has long been famous for technical innovation in all areas of industrial production. The largest company on the European market, specializing in the production of wall-mounted gas boilers under the world-famous Immergas brand, was no exception.

Using only the latest technologies and modern design in its developments, the Immergaz gas boiler is distinguished by its reliability and high quality. The company is so confident in its products that it provides an unprecedented extended warranty of 5 years!

By offering the Immergaz gas boiler to the modern heating market, the company took care of expanding the range of equipment so that the boilers can be used not only in residential buildings, but also in industrial facilities, offering mini boiler rooms for large areas.

Our review is devoted to wall-mounted modifications of boilers called NIKE STAR 24 3 R, NIKE MYTHOS 24 3R, and EOLO STAR 24 3R - which have become bestsellers on the domestic market. Let's consider their features, principles of operation, technical characteristics. Let’s try to create our own opinion about the advantages of the engineering solutions of Immergaz specialists, talk and leave feedback on possible disadvantages.

Each season has its own regime

Modern boilers are very easy to adjust a variety of parameters, including the intensity of fuel combustion. This function was introduced for a reason, but to prevent excessive fuel consumption due to clocking. It is recommended to choose your own regime for each season:

1. Winter - maximum or average power.
2. Spring, autumn - minimum power, in March and November - average.
3. Summer - the boiler is not used, or - minimum flame.

However, these settings are relevant if the boiler matches the size of the heated room. Many people take equipment “with a reserve” of power, implying severe frosts, deterioration of the heat-saving properties of housing, or an increase in the area of ​​​​the premises. In this case, it is recommended to immediately set the flame to minimum, especially if the boiler is wall-mounted.

Burner adjustments may stop working or operate incorrectly over time. If boiler repair is not possible, you can change the flame power using a valve on the gas pipe. This method is rarely used in practice, since valve wear can lead to leaks.

Setting the unit power

You can adjust the optimal power of the Imeergas gas boiler using the gas valve. Setting the operating power of a gas boiler is carried out as follows:

• set the DHW switch to the desired position;
• open the hot water tap;
• adjust the required power using the adjustable nut on the gas valve;
• adjust the heat output by turning it clockwise to increase it, or counterclockwise to decrease it.

The minimum heat output can be adjusted using a plastic screw located on the gas valve. The adjusting nut must remain motionless. It is recommended to turn off the power to the valve modulation coil and then turn the screw clockwise to increase the pressure or counterclockwise to decrease the pressure. After this, the power to the coil must be returned.

Note! The minimum power should not be less than that specified in the characteristics of the unit.
