Installation of wall-mounted gas heating boilers - connection diagram with examples

Owners of private houses are often faced with the question: what is the optimal temperature to set on a gas boiler to keep it warm and economical? Of course, it will be impossible to clearly answer this question using numbers, because there are quite a lot of unknown variables: how many m² need to be heated, how well the house itself is insulated, what are the weather conditions outside, the boiler model and the degree of wear and tear of the entire heating system.

Therefore, the best solution would be to turn to the services of specialists who will not only conduct a thorough analysis, but also set up the automatic heating boiler themselves for maximum efficiency at low fuel costs.

But we can give general recommendations. After the experiments, we can say for sure that at the minimum temperature the gas consumption will be the highest. Why? Read on.

Characteristic

Ariston gas equipment is produced in two basic versions - floor-mounted and wall-mounted.
In private homes, as a rule, wall-mounted models are used. Depending on the model parameters, the unit may have an open or closed combustion chamber.

In the first case, combustion products are removed from the boiler naturally, in the second, a forced gas exhaust system operates. Typically, closed chamber installations are connected to a coaxial chimney. The coaxial pipeline implies the presence of two structural layers, due to which it is possible to simultaneously remove carbon monoxide and provide a flow of fresh air into the firebox.

In addition, the chamber has a built-in fan, which is responsible for the timely removal of burnt gas and hot air. These models are more secure than devices with an open camera.

Floor-standing boilers have quite high power

, therefore they are used for industrial purposes or in residential buildings with a large area. Usually they are designed only to supply heat to radiators and radiators, so if you need to heat water, you should additionally purchase boilers.

The main element of any boiler equipment is the burner, which is responsible for burning fuel and supplying heat to the heating system. Burners can be conventional or modulating. Modulation ones are more modern and technologically advanced, since they allow you to automatically adjust the power of the device depending on the results of internal control over the temperature level.

Ariston double-circuit boilers have 2 heat exchangers: the first is necessary to provide hot water supply, and the second is directly for heating the main coolant. Their production can be carried out in three versions: they are separate, bithermic or with a boiler.

Two autonomous circuits are simultaneously placed in the common boiler body:

• heating - it is responsible for supplying radiators with heated water;
• water - this mechanism is connected to water pipes.

Water can be heated in several ways:

• flow-through - this option only works when using hot water: after passing through the burner, it reaches the end consumer in heated form;
• boiler - such a device implies the presence of an additional tank in which water heated to a given temperature accumulates and from there it flows into the tap.

Based on the location of the circuits, boilers are divided into 2 types.

• Bithermal - in such installations the water pipe is located inside the heating system. In this case, the heating circuit heats up more actively and transfers part of its heat to the water supply.
• Duothermal - include two tubular heat exchangers that evenly transfer heat to both systems. In this case, energy is used most efficiently, however, the heating rate is significantly reduced. In addition, this operating principle creates the preconditions for the appearance of lime deposits, so such devices require regular cleaning.

Depending on the combustion method, Ariston boilers are conventionally divided into those operating on the principle of turbocharging and natural draft. A turbocharged boiler has a fairly high heating rate, however, gas is also consumed in large volumes. The second type of model heats water rather slowly, but fuel consumption is also more economical.

How it works

To minimize problems with the device, you should study its structure and operating principles. Typically, private households use storage models rather than flow-through ones, which allow them to use electricity more efficiently. Such a device consists of a heat exchanger tank, inside of which a heating element is installed - a heating element, connected to the power supply.

An important part of the device is the thermostat. This element allows you to maintain a constant temperature of the water inside the storage tank. Water flows through pipes into the heat exchanger. If its temperature is too low (and this is usually the case), then the thermostat sends a signal and turns on the heating element.

The water is heated until it reaches the required temperature. After this, the thermostat operates again and turns off the heating element. Hot water is taken from the tank and replaced with cold water, the heating process is repeated again and again. This is a general diagram of the design and operation of a conventional storage water heater.

Flow models are designed somewhat differently. They heat not a static volume of water, but a flow. They use more powerful heating elements that start when the water is turned on and stop when it is turned off. To study the operation and design of a particular model in more detail, you need to carefully read the technical documentation accompanying it.

The heater tank is a durable stainless steel container, one or two millimeters thick. No matter how resistant this material is to corrosion, these processes still periodically arise and develop, which leads to water leaking from the device. One of the common causes of such breakdowns is electrocorrosion.

To prevent it, you need to regularly, i.e. annually replace the magnesium anode installed inside. This element is designed specifically to prevent electrocorrosion

Over time, it wears out, and storage tank owners overlook replacing this important part.

As a result, the tank, which has been serving well for some time, suddenly begins to leak. The incorrect condition of the magnesium anode can also affect the condition of the heating element. On the outside, the storage tank is usually enclosed in a metal or plastic housing, and it also has an insulating shell that prevents heat loss.

Damage to the outer shell and insulation occurs rarely, usually due to careless handling of the device. Cracks and chips on the body of the water heater may not disrupt its operation, but this will lead to a deterioration in the properties of the heat insulator and will negatively affect the functioning of the device as a whole.

Inlet and outlet pipes for cold water and outlet pipes for hot water usually do not cause any problems if the heater is installed correctly. Typically, a water heater is equipped with two thermostats, one of which is designed to control the water temperature, and the second monitors the condition of the first device.

Sometimes a third thermostat is used, which determines the working condition of the heating element. In any case, a broken thermostat will have to be completely replaced. There are capillary, rod and electronic types of thermostats. Their design is different, but the principle of their operation is similar.

The insulating gasket not only serves to seal the connection between the elements of the water heater, it is also necessary as an electrical insulator. It is recommended to replace this element regularly during each maintenance of the water heater.

The thermostat shows to what temperature the water inside the device is heated. If this element breaks, the water heater will still perform its functions, although data on the degree of heating will not be received.

Ariston double-circuit gas boiler: instructions

Types and features of the design of Ariston double-circuit boilers

If we talk about installation, Ariston double-circuit gas boilers are available in floor-mounted and wall-mounted types.
Floor-standing boilers are placed on a flat, stable base. They have a steel or cast iron heat exchanger, so they are quite heavy and bulky. Very durable and can last quite a long time. A more compact and lighter wall-mounted gas boiler Ariston, with a copper or stainless steel heat exchanger. The quality of operation of such boilers directly depends on the pressure of energy carriers (gas and water) in the pipelines. The Ariston double-circuit gas boiler functions as a house heater and as a water heater. One circuit supplies heat to the radiators in the form of hot water, and the second circuit heats domestic water. When a hot water tap opens, the valve automatically closes and the boiler begins to work to heat the newly incoming cold water.

Ariston gas boilers come with an open or closed combustion chamber. The open type of chamber implies an influx of air from the home where the boiler is located; combustion products are removed through ventilation. A boiler with a closed combustion chamber requires a forced draft device, that is, air is taken in from outside the room, and combustion products are also released. There are built-in fans for this. Expansion tank 8 liters. The power of Ariston gas boilers can be either 24 kW or 28 kW, which is enough to heat an area of ​​500 sq.m.

There is protection for blocking the pump, against scale and freezing. The equipment has a self-diagnosis system; all possible errors and failures are displayed on the liquid crystal display. There are several modes that the Ariston double-circuit gas boiler is equipped with, the price of which does not depend on what mode is present in the boiler.

The following modes exist:

“Chimney Sweep” - the mode is responsible for the operating power of the gas burner. “Auto” mode – is responsible for a comfortable microclimate in the room. Any gas, double-circuit boiler listens to commands from external temperature sensors and, based on the data received, normalizes the burner gas pressure by opening and closing the supply valve. “Comfort” mode – regulates the operation of the second circuit, which is responsible for heating water for domestic use. The Comfort function maintains the desired temperature to quickly provide water for the bathroom or kitchen

When choosing a boiler, it is very important to take into account all parameters in order to save energy resources.

Just like Ariston wall-mounted gas boilers, Ariston floor-standing boilers also have different types of control: climamanager, t-control.

Popular double-circuit gas boilers Ariston

These gas boilers are capable of operating at low gas pressure (up to 5 mbar), neither water flow nor low pressure in the main line has any effect on the functionality of the boiler. Changes in voltage in the electrical network are also not a hindrance. The heating power can be reduced, but the water heating power does not change. There are options: start delay, continuous electronic modulation of the flame in the burner, protection against frost, against the accumulation of scale on heating devices, prevention of blocking of the pumping system and three-way valves.

The Ariston Egis Plus 24 FF gas boiler is equipped with independent diagnostics.

Three-way valve with motor drive. The boiler has two NTC sensors, two filters for mechanical cleaning, and an 8-liter expansion tank. If desired, you can connect a room thermostat and a T-Control digital thermostat-programmer. You can read how to choose a gas boiler for your apartment here.

The circuits are equipped with filters. Taking into account all the advantages, the Ariston double-circuit gas boiler price is not high. But excellent efficiency.

Quiet and lightweight. Combustion chambers are found both open and closed. Maximum power 35 kW. Thanks to sensors, it “feels” the weather and adjusts the boiler itself, focusing on the climatic conditions outside the window. You can set the temperature support level for a specific day of the week. For example, if you leave home every weekend, the boiler will not heat up at full capacity on those days. To buy a double-circuit wall-mounted gas boiler Ariston, you don’t have to go far. This line of boilers is known in almost every city.

CLAS B 24 CF – gas convection wall-mounted boiler. It has an open combustion chamber, electric ignition. Heat exchangers are made of copper. One of the advantages is the presence of a built-in circulation pump, a 40-liter boiler, and a built-in 8-liter expansion tank. Equally capable of operating on natural and liquefied gas. Equipped with a “Comfort” function. There is a power indicator, thermometer, pressure gauge, auto ignition, flame modulation.

BS II - economy-class wall-mounted double-circuit boilers with a power of up to 24 kW, operation and management are simplified as much as possible, designed for heating apartments and providing hot water to residents of apartment buildings. It is distinguished by uninterrupted boiler service when the pressure in the lines decreases. For this purpose, the option “continuous electronic modulation of the burner fire” is provided, a whole set of options ensuring the safe use of the boiler.

It must be said that any Ariston 24 wall-mounted gas boiler, reviews confirm this, is equipped with the following safety functions: semi-automatic replenishment, pumping air out of the system, blocking the operation of the circulation pump, protection against freezing and scale accumulation. Compared to other brands, the Ariston BS 24 FF gas boiler is inexpensive, heats up quickly and is very energy efficient; there will be an excellent bonus in the form of reduced payments for housing and communal services.

Economical, with a closed combustion chamber, protection against scale accumulation, non-freezing. Each Ariston double-circuit gas boiler has self-diagnosis; during use, you need to monitor the readings on the liquid crystal screen; it displays all failures and errors in the operation of the boiler.

The Ariston double-circuit gas heating boiler has two types of condensation model:

• Genus Premium is a boiler with a closed combustion chamber, a built-in circulation pump and a 120 liter boiler. You can connect remote control. Runs on natural gas and liquefied gas. We do not freeze, and has a “warm floors” mode.
• Genus Premium SOLAR - the same, only a 180 liter boiler. The control system is connected to solarsatelite and controls the solar system. The prices for these Ariston gas boilers are also not high.

Boiler malfunctions

Most problems that arise can be prevented during the installation of the boiler. Here is a list of the main malfunctions, their causes and measures to prevent device failure:

• Failure of the control board. As a rule, it occurs due to poor quality of electricity - power surges, frequent power outages. To prevent breakdowns for this reason, it is necessary to install a voltage stabilizer. For a private home, a good solution would be to install a backup diesel generator and an automatic transfer system. It is necessary to protect the device with a circuit breaker, power it via a separate cable line and reliably ground it.
• Deterioration in the nameplate characteristics of the device, expressed in underheating of water or reduced performance when heating. It is associated with the presence of contaminants in the water and excessive water hardness. In both cases, deposits appear on the heat exchanger tubes, making it difficult to heat and pass water through the system. To solve the problem of contamination, it is necessary to install a filter, and when using water with a high calcium content, it is recommended to heat the water to 45-50 °C.
• Frequent stops due to insufficient water pressure. The malfunction is detected by the device and causes a protective stop. BEFORE purchasing the unit, it is necessary to find out the parameters of the supply water network and make changes to it if the pressure is below 1.5 bar. If the pressure is higher than 6 bar, then install a pressure relief valve. If the parameters of the main network are normal, then turn off the boiler and check the system for leaks.
• Frequent stops on the smoke removal system. BEFORE installing the unit, calculate and install flue ducts and a chimney that will provide the required draft.
• Frequent stops due to lack of air. Before installing the device, equip the room with a supply ventilation system.
• Non-compliance of operating modes with the stated ones, non-compliance of the coolant with the specified parameters. The main reason is incorrect commissioning and incorrect device settings. Carefully reading the instructions often solves the problem. If necessary, you should involve a qualified specialist who will carry out commissioning and provide instructions on how to use the device.

Here are the basic recommendations when installing a gas boiler, which will avoid most problems:

• When choosing a model, contact a company that will select the necessary equipment based on your requirements;
• Entrust the installation and commissioning of the device to a qualified specialist;
• Please read the operating instructions carefully;
• Do not neglect periodic preventive inspections and maintenance of equipment;
• In case of any frequently recurring malfunction, turn off the boiler and call a qualified specialist;
• Entrust repairs and supply of spare parts only to a certified organization.

Malfunctions of heating boilers

Mostly, major malfunctions begin to appear during the heating season, when two boiler circuits are operating - heating and water heating. It may happen that it does not start at all, or does not heat well enough. With the launch, the issue will have to be resolved separately, but if the water does not heat up enough, then the reason may be a clogged heat exchanger. As you know, the water quality in our systems is far from ideal, and besides, few users install it in front of the boiler. This is where the heat exchanger becomes clogged, resulting in poor boiler performance.

Here are the most common malfunctions of gas boilers when they do not heat the water well:

• periodically switches off spontaneously,
• smokes a lot,
• does not develop enough power,
• makes noise
• clogged,
• the pump is broken.

If it happens that the gas boiler does not heat the water, then often the reason is the formation of limescale on the walls of the heat exchanger, which, as it accumulates, becomes very durable and not only reduces the water temperature, but also reduces the throughput of the boiler. The thermal conductivity of scale is tens of times less than that of metal, so it is not surprising that the boiler does not heat the water. If you do not take any preventive measures, then very soon you will have to completely disassemble the boiler and remove deposits mechanically.

This problem can only be helped by timely action, and it should be done regularly, especially if cleaning and softening filters are not installed in front of the boiler.

Special chemicals are used for flushing, but they should be used with great care, since they are equally destructive to lime deposits and to the material from which the heat exchanger is made. It is best to invite a specialist for this purpose. To ensure safe and efficient operation of your gas boiler, preventative maintenance is recommended.

It is advisable to do this regularly before the start of the heating season; you should not wait for a situation when the boiler does not heat the water. This approach will ensure its long service life and economical operation. Major repairs are carried out as needed by a service center employee - it is strictly prohibited to do this yourself

Vailant boilers are particularly reliable and safe. Breakdowns of such complex equipment must be repaired by a specialist. But, minor faults can be removed yourself if you have a basic level of knowledge about the design of heating and heating boilers.

Most faults are indicated on the boiler display. Having deciphered the errors, you can figure out the reason for the boiler’s failure to heat water. Where to start searching if water heating in the Vailant boiler does not work and the indicator does not show an error or can it be interpreted in different ways?

Gas equipment manufactured by Ariston

Gas production equipment, depending on the model in question, is designed for installation in autonomous heating systems with an area of ​​up to 500 m2. Note that these models are capable of not only heating the coolant, but also capable of providing the user with hot water supply.

The Ariston double-circuit wall-mounted gas boiler is distinguished by its compact external dimensions, as well as simplicity and ease of operation and maintenance. To install the equipment, you do not need to allocate a separate room, as, for example, for liquid and solid fuel heating devices.

Thanks to the wide power range, equipment produced by Ariston can easily be selected for installation in a specific system, based on the characteristics of the room that will be heated.

Gas equipment "Ariston"

1. The language menu on absolutely all models offers Russian.
2. The AUTO function is installed, which allows you to automatically adjust the power based on the internal and external air temperatures.
3. Absolutely all Ariston units have heat and sound insulation.
4. The manufacturer provides a two-year warranty on all its traditional-type products, and a three-year warranty on condensing products.

Equipment safety is ensured by the following built-in functions:

• semi-automatic refill;
• pumping air out of the system;
• blocking the operation of the circulation pump;
• protection against freezing and scale formation.

Ariston double-circuit turbocharged gas heating boilers are distinguished by their simplicity and ease of operation and maintenance.

Main advantages of the equipment

Ariston equipment is offered in two versions: wall-mounted and floor-mounted

• with an open combustion chamber (combustion products are removed naturally);
• with a closed combustion chamber (removal is carried out in a forced manner).

Equipment with a closed chamber is connected to a coaxial chimney. The difference is that these models have a built-in fan, thanks to which combustion products are removed in a timely manner.

The main advantage of devices of the second type is high safety, and also in the fact that air is taken from outside the room, while devices of the first type take the oxygen necessary for normal gas combustion from the room.

It is important to note that Ariston double-circuit wall-mounted gas boilers stop working to heat the coolant immediately after the hot water intake is turned on. This point is important to consider when choosing and purchasing a device.

Design features and equipment design

Design features and device

All proposed gas boiler options differ in the type of combustion chamber: closed or open. If the device is equipped with an open chamber, then it will need to be connected to the chimney, while air is taken from the room in which the unit is installed.

If the Ariston wall-mounted double-circuit gas heating boiler is equipped with a closed chamber, then the combustion products are removed forcibly using a built-in fan. Such equipment is connected to a coaxial chimney. Air is taken from outside the room, which is a big advantage, since the oxygen in the room is not burned during operation of the device.

Ariston gas wall-mounted double-circuit heating boilers have two heat exchangers in their design. One is intended for heating process water, the second for heating coolant. Their production can be carried out in several versions: bithermic, separate and with a built-in boiler.

gas boiler Ariston Egis 24 CF NG characteristics

• the device menu is displayed in Russian; if necessary, you can easily set the required temperature for heating the coolant and hot water;
• high resistance to sudden changes in voltage in the network;
• the equipment will continue to operate stably even with reduced water and gas pressure in the relevant systems;
• ease and convenience of installation, maintenance and operation;
• high efficiency in operation.

All operating parameters are displayed on the built-in display, which makes it easy to monitor work processes and, if necessary, make the required adjustments to them.

The Ariston double-circuit wall-mounted gas boiler can have in its design special sensors for determining internal and external air temperatures. All operating parameters are displayed on the built-in display, which makes it easy to monitor work processes and, if necessary, make the required adjustments to them.

Causes of malfunctions of gas-type boilers

Even if the operating instructions for the Ariston gas boiler are thoroughly studied, it is impossible to insure against the fact that the device breaks down. There are many reasons why equipment can fail, for example:

• maintenance of the device was not performed in a timely manner or with violations;
• insufficient air supply to the combustion chamber;
• unprofessional repairs or maintenance of control units or burner regulation;
• low-quality spare parts were used during maintenance;
• Incorrectly set temperature.

There are other more complex breakdowns of gas heating boilers that should only be repaired by a service employee. Therefore, regardless of the complexity and cause of the malfunction, the Ariston double-circuit gas boiler must be repaired and serviced by a technician who has not only special tools and experience, but also special permission to carry out repairs and maintenance of gas heating boilers.

Features of some models using the example of Ariston EGIS Plus 24

The EGIS Plus 24 gas boiler is equipped with a dual-circuit heating system, a closed combustion chamber and a wall-mounted housing. They can heat an area of ​​up to 250 square meters. m. In addition to automatic protection against major disasters (overheating, freezing or jamming of the pump), there are two important features. This is the ability to easily tolerate all power surges and stable operation under conditions of low gas pressure.

But, despite such a well-thought-out design, this model also has weak points. So, the sp3 error appears in it much more often than others. In various situations, the flame does not burn, even under seemingly favorable conditions, to the point that the masters shrug their shoulders. And they adjust the valves, check the access and removal of air/exhaust gases, clean the scale, and still the error can happen again at the most unexpected moment.

According to owner reviews, the supposed causes of the sp3 error look different. Either the connection to the water supply via a hose seems to be interfering, or an error appears after switching to the heating system after using hot water. In general, EGIS Plus is considered a reliable model, but defects that appear, such as the described floating error, reduce its popularity.

Small boilers for heating using gas are now often used in houses and apartments, and many of the best such devices are produced under the Italian brand Ariston. We will look at some models of this brand and provide instructions for the Ariston gas boiler regarding these models.

This brand is known all over the world. Its roots, like many other great brands, come from the early 20th century, when enterprising Italians started a family business. Nowadays, Ariston household appliances do not need any recommendations.

Ariston gas boilers, if you do a brief review, reveal themselves to be very reliable and popular. The company mainly specializes in wall-mounted domestic boilers with two heated circuits - for heating and for hot water supply. They are presented in several series:

• Genus;
• Clas;
• Egis;

The first family has rich functionality. The second family is famous for its practicality. The third series is distinguished by the compactness of the boilers coupled with their excellent design. We'll talk about the models of the last two series below. Every type of Ariston gas boiler has good reviews from consumers everywhere.

User manual

The first thing you need to remember before you start installing a gas boiler is that the installation and connection of the device should only be carried out by certified specialists. Self-installation is not recognized by gas services as legal; in this situation, the inspection company has the right to shut off the gas supply to the house and impose a fine on the owner of the premises. And this is at best, and at worst, the boiler can fail or even explode and cause harm to life, health and property.

Before starting use, you should check the level of ventilation - the room where gas equipment is installed must be well ventilated. Throughout the entire period of operation of the boiler, it is necessary to constantly monitor the water pressure in the heating system. Normally it is 1.5-2 bar; if the pressure drops, the boiler turns off and the control display shows an error. In this case, you should make sure that there are no leaks and “feed” the installation.

Even if the installation and connection were carried out by professionals, and the boiler was used strictly according to the instructions, there is always a possibility of the device breaking down.

There are many reasons why a unit may fail, but the most common are the following.

1. Damage to the control board. This problem is usually associated with frequent power surges or power outages. To avoid problems even at the installation stage, you should think about installing a voltage stabilizer, and for a cottage, a backup generator that is equipped with a circuit breaker and grounded can be an excellent option.
2. Low efficiency or underheating of water. Such damage is often accompanied by excessive water hardness or the presence of contaminants in it, so experts recommend using water filters.
3. Stops due to lack of oxygen. This defect occurs if the room is not equipped with a supply ventilation system.
4. Inconsistency between the actual parameters of the coolant and the declared ones. This problem is a direct consequence of improper installation of equipment and illiterate settings of the boiler.

And in conclusion, a few recommendations:

• do not neglect regular preventive inspections of the boiler and its quality maintenance;
• if a particular malfunction recurs too often, you should contact the service company;
• repairs should only be trusted to a certified organization whose specialists have all the suitable spare parts and necessary tools, and in addition, have the required permits to work with gas equipment.

With proper installation and operation, a 2-circuit boiler from Ariston will last at least 20 years.

Descriptions of the Ariston double-circuit boiler

One of the most important components in all gas boilers is the burner, in this case it can be modulating or conventional. The first option is more popular than the second. When using it, the entire system will be adjusted automatically, without human intervention. In this case, the power of the installed heating equipment depends on temperature indicators.

The burner is also divided into 2 types:

open;

The safest is since it does not involve combustion products entering the room in case of emergency. Also in this case, the owner does not have to worry about building a chimney. A special coaxial pipe must be connected to the closed burner; it can always be brought outside in any accessible place.

An open-type Ariston boiler, in any case, requires a chimney to remove combustion products to the street. Also, do not forget about natural cravings. Air will enter the system from the living space, so it will have to be constantly ventilated.

The coaxial pipe used in a closed combustion system has the advantage of being made of 2 layers. One is necessary to remove combustion products, and the other will ensure fresh air enters the boiler. Thus, the owner of the equipment does not have to constantly ventilate the room and worry about natural draft. The room will always have a sufficient amount of oxygen.

Technical data of Ariston gas appliances

• Ariston boilers are used for heating and water heating, that is, they are double-circuit.
  Each modification has its own characteristics, but the common type of fuel is gas.
• The gas combustion chamber can be either open or closed.
  If there is a chimney, units with an open chamber are used. And in apartments of multi-storey buildings, where there are not always chimneys, equipment with a closed combustion chamber is used.
• Power.
  Using this indicator, the gas consumption required to heat the room is calculated.
• Compactness.
  Wall-mounted units are used in small, narrow rooms. Floor-standing units used in production or warehouse areas are heavier and require more space for installation.
• Availability of a control unit.
  This element is indispensable when the water is turned off or when there is a sharp decrease in gas. In case of any malfunction, the unit will immediately turn off the device, which will prevent breakdown. It can also help you save fuel consumption.

Device selection

When choosing a device, you must be guided by the following criteria:

The area of ​​the heated room in m2. It is necessary to select a boiler based on 1 kW of thermal power per 10 m2 of room. At the same time, it is necessary to understand that this is an ideal option and, taking into account the heat loss of the living space, the average annual air temperature at the installation site and the radiators used, it is necessary to introduce a correction factor. For a preliminary assessment, we recommend using any online calculator that takes into account the above factors and also makes adjustments for the location of the walls (windward or not), ceiling height, and type of windows.

Need for hot water. For high consumption, it is wise to choose the CLAS B model with a built-in boiler, which is more economical.

Boiler installation location. For water heating units with an open combustion chamber, it is necessary to equip the room with forced ventilation, since the combustion air comes directly from the room

Since devices with an open combustion chamber are designed to remove combustion products through a chimney with natural draft, it is necessary to provide for the installation location of the chimney and chimneys. IMPORTANT! It is not allowed to pass chimneys through structures made of flammable material.

How to work with the menu

By pressing the “OK” button once, the number 2 will blink on the digital indicator - this will be the first digit of the future three-digit code (Menu Group Number)

Using the plus and minus buttons you can change this value from group number 2 to any other group. To fix the selected group for further entering the code number, you need to press “OK” again - after this the second digit of the future three-digit code begins to blink (Submenu)

Having selected a submenu, fix it by pressing the “OK” button again and similarly select and fix the third digit (Parameter)

All! Now the screen will no longer display the three-digit code itself, but the set value of this parameter, which can be changed by pressing “plus” or “minus”. Having made the necessary changes, do not forget to commit them by clicking “Ok”.

Please note that after selecting the desired menu, after a few seconds of inactivity, a three-digit code will begin to be alternately displayed (to remind you where you are) and the parameter corresponding to this menu.

The ESC button is used to exit the settings menu and return to the previous step. The exit is carried out step by step, one press is equal to one step back.

Let's practice

Now, if you want, practice to better understand the switching order. For example, enter menu code 701; this will turn on the forced air removal mode, essentially turning on the pump in the boiler for 6 minutes.

When this mode is turned on, the “P I -” symbol will light up on the display. You can exit the “Anti-Air” mode without waiting 6 minutes by pressing ESC.

Then, using ESC, try to go back and switch to mode 300, which means (Set water temperature in the boiler) in the values ​​you can see the temperature that is currently set by your DHW regulator.

Ariston boiler menu structure

At first it may seem complicated, but once you figure it out, everything will be simple and clear, so:

Each parameter is indicated by a three-digit digital code. For example 228 (this is just a parameter code that depends on the boiler version)

The first digit of the three-digit code means a separate menu group; the boiler has six separate menu groups, each responsible for its own settings section. Here they are.

2 - Boiler settings

3 - Solar collector and storage boiler

4 - Zone 1 parameters

5 - Zone 2 parameters

7 - Testing and maintenance

8 — Technical parameters.

The second digit of the three-digit code indicates the submenu, and the third is the parameter itself to which access is granted.

For example, code 228, already known to us, is deciphered as follows: 2 - Boiler settings (this is the Menu), 2 - Basic boiler settings (Submenu), 8 - Boiler version (Parameter).

So by typing the three-digit code 228 we get access to the set value of this parameter, which, according to the table, can vary from 0 to 5 and depends on the boiler version.

I will provide tables with menu codes and a description of what is regulated by a specific code below, but for now let’s figure out how to enter the boiler service menu.

Features of replacing a faulty heating element

If the boiler stops heating the water to the required temperatures, then the heating element should be replaced. To do this, you need to perform the following procedure:

• Disconnect the device from the electrical network.
• Stop supplying water to the container.
• Connect a hose to the drain valve and drain all the water into the sewer.
• Remove the protective box by removing 2 screws.
• Remove the return valve from the pipe.
• Drain the remaining water from the tank.
• Using a wrench, unscrew the nut that secures the flange.
• Carefully remove the old heating element without damaging the flange.
• Clean the walls of the container from accumulated dirt. If the inside walls have a special protective enamel, then there is no need to remove scale. You may simply damage the protective film. This layer of scale will protect the walls of the vessel from rust formation.
• The magnesium anode is removed and repaired if required.
• A new heating element is being installed. You need to do exactly the opposite of all the work.
• Checking operation after final assembly of all parts. The tank should not leak. Otherwise, you need to put in new gaskets.

Operating instructions for Ariston gas boilers

Before purchasing an Ariston gas boiler, you need to understand that if the buyer does not understand its installation, it is better to contact experienced specialists and entrust all the work to them. After all, even with the most detailed instructions, it is not a fact that the matter will end successfully. In this case, there is every chance of damaging the equipment, after which you will have to call repairmen, and this will result in additional costs.

It is very important to keep children away from the equipment. To do this, after, you need to have a conversation with them and explain in accessible language that you cannot twist or place anything on the unit, this should only be done by an adult

If the family leaves, for example, on vacation, after the boiler is turned off, it is also necessary to shut off all gas and water supply pipes. Only after this is the equipment disconnected from the network.

If any model has a display, all indicators that it displays must be strictly monitored. It may display any problems or deviations from normal operation that occurred during the heating process.

One of the most important points in the instructions for gas equipment is safety precautions. Before connecting the boiler, you need to familiarize yourself with it first.

For what reasons does an Ariston gas boiler fail?

There are options when all connection and operation parameters have been met, but the heating boiler is still faulty?
Like all equipment, gas units can also fail. There are reasons for this:

• a malfunction may occur due to the fact that some maintenance rules were violated, or the installation was unsuccessful;
• Malfunctions of the Ariston gas double-circuit boiler also occur when there is insufficient air supply. The combustion chamber must constantly receive air in order for it to operate at full capacity. If there is not enough of it, then, accordingly, various problems with the boiler will appear;
• Malfunctions may also appear due to incorrect work carried out by specialists when servicing the control units or adjusting the burner;
• The market is full of low-quality products, so spare parts are also often found to be of low quality. Even if the installation or replacement of something went well, a malfunction can still appear precisely because of imperfect spare parts.

This is not the entire list of breakdowns that can occur with a gas unit. But one condition for repairing all models of Ariston boilers must be fulfilled - calling a specialist who understands such issues to your home. Working with gas equipment is far from a safe task, which is why it must be carried out by experienced employees who have permits for repairs and all the necessary spare parts.

Advantages and disadvantages

Ariston gas boiler systems are popular all over the world, this is due to their exceptional performance characteristics:

• effective built-in protection system against power surges in the network - devices can operate in the voltage range from 150 to 260 V;
• the ability to effectively regulate the rate of water heating: in the case when the flow rate does not go beyond 6 l/minute, the temperature can reach up to 37 degrees; in order for the water to heat up faster, you simply need to increase the boiler power;
• simultaneous operation in the mode of a water heater and an efficient heating device;
• the ability to automatically shut off the gas in the event of flame extinguishment, regardless of its causes;
• automatic shutdown of the heater if the water pressure in the system drops to a critical level;
• the presence of two heat exchangers;
• wide range of models;
• excellent adaptation to use in Russian conditions;
• Italian assembly;
• European quality control system.

However, there are also disadvantages, among them the following should be highlighted:

• very high cost in comparison with analogues;
• use of components produced in China.

Russian users highlight boilers of this brand as high-quality, reliable and practical. Reviews from owners of private houses indicate such advantages of Ariston as compact dimensions, energy-efficient gas consumption and ease of control of the mechanism. Among the disadvantages is the dependence of its operation on the power supply, but this feature concerns not only Ariston - almost no gas equipment operates without being connected to an alternating current network.

Plunging into history

Few people know that the history of the company, which today produces the best heating boilers in its segment, began with a small family-type enterprise. The talent of its founders - the Merloni family - turned a small company into a thriving company with a huge staff of talented employees.

The success of the enterprise lay in the stable improvement of product quality. It was this priority that was set by the leaders of Ariston. Naturally, trust in the brand grew every year, as the brand offered increasingly higher quality, reliable and durable units, the functionality of which was also steadily expanding. This applies to absolutely the entire Ariston product line.

Vittoria Merloni, the founder of the company, sought to satisfy the needs of the market to the maximum extent possible

He paid attention to the smallest requests of potential clients. As an example, from a certain point the product undergoes a safety test for pets

Even today, few manufacturers care about this parameter. For Ariston, this is one of the stages of monitoring the safety of its products.

Over the years of its existence, the company has accumulated sufficient experience in the production of water heating equipment to today offer customers perfect engineering solutions in all respects. Today, Ariston can rightfully be considered one of the leaders in the household appliances market, since the company occupies an honorable third place in the world in terms of sales volumes. Naturally, heating equipment brings the lion's share of all profits. That is why the newly formed subsidiary Hotpoint-Ariston, part of the famous Indesit Company, is one of the priority objects for investment of the large giant's funds.

In practice, everything is so - the corporation is investing serious amounts in the development of Ariston’s scientific and technical base, education and training of its personnel, as well as expanding the range of products offered. That is why we can safely say that the manufacturer will surprise consumers more than once with interesting technical solutions aimed at ensuring comfort in the homes of its potential buyers.

• 92/42/EU regarding energy efficiency
• 2014/35/EU regarding electrical safety

Disposal and recycling.

Our equipment is designed and manufactured from recyclable materials and components.

The boiler and its accessories must be disposed of properly and separately in separate categories where possible.

The packaging used for transporting the boiler must be disposed of by the installer or seller.

ATTENTION !!

Recycling and disposal of the boiler and accessories must
be carried out in accordance with the requirements of the rules and regulations applicable to this equipment.

Weaknesses of the water heater

The Ariston brand is considered one of the most reliable. But despite this, these boilers have their drawbacks. Very quickly after purchasing the device and starting its operation, the display indicating the main parameters of the boiler’s operation breaks down. However, it is intended for the convenience of the user. A broken display does not affect the operation of the boiler in any way.

Although the manufacturer indicates that the device is frost-resistant, the water from it must be completely drained during downtime. Frozen residues may damage the device.

The temperature maximum of the Ariston boiler is 80 degrees. But it is not recommended to use it. The boiler will fail very quickly in this case. It is best to heat up to 60 degrees.

If all these disadvantages are taken into account during operation of the device, then it will last for many years.

Do-it-yourself Ariston water heater repair in the video below:

Some of the existing breakdowns can be easily fixed on your own; for some, the equipment will have to be taken to a service center.

Cold or insufficiently hot water flows from the boiler

The cause of a malfunction of this nature may be a breakdown of the heating element, thermostat and a large layer of scale on these devices. Before determining the cause of the malfunction of the Ariston 80-liter water heater and doing the repair yourself, you should turn off the power supply and drain the water.

Then, using a 13 mm wrench and a Phillips screwdriver, remove the protective box and unscrew the bolts on the mounting plate

Carefully remove the flange on which the heating element and thermostat are attached. Now you need to descale these 2 devices

The thermostat should be unscrewed, cleaning the attachment points to the flange from sediment, then carefully, using a screwdriver, free the thermostat from scale. You can check the functionality using a tester; the absence of a signal on its contacts indicates a malfunction and the need for replacement, since the thermostat cannot be repaired

You can also check the heating element for functionality using a tester by connecting the ends of the tester to the contacts of the heating element. If there is voltage, the heating element is working, but it needs to be cleaned

The heating element can be cleaned using a screwdriver, carefully removing pieces of deposits

Then you need to prepare a solution of citric acid - 100 g per 1 liter of water and immerse the heating element in the solution. The effect of the solution on the device will be indicated by air bubbles that appear as a result of the reaction. If this action is not enough for complete cleansing, you can put the vessel with the solution and heating element on low heat.

After cleaning the heating element, you need to descale the tank

Be careful not to damage the inner surface of the tank. If it is possible to remove the heater from the wall, cleaning can be done using a solution of citric acid, pouring it into the tank

After these manipulations, assemble all the parts in the order in which they were disassembled and carefully insert and secure the flange. Make sure that during assembly there are no distortions of parts, do not overtighten the bolts, change the gasket between the body of your storage boiler and the flange, since the flange gasket was also exposed to salts

Filling the heating system with water

Starting a gas boiler begins with filling the heating system with water. Everything is simple here - modern double-circuit boilers do not require the installation of a special system feeding unit. It is already built into the boiler and equipped with a special tap, which, as a rule, is located at the bottom of the boiler in close proximity to the cold water connection pipe. Open the feed tap and slowly fill the system with water.

Starting the boiler - how to fill the system with water

A very important point in the operation of any boiler equipment is fluid pressure. To control this parameter of the heating system, almost all boilers are equipped with a pressure gauge. During the process of filling systems with water, it is necessary to monitor the pressure and after it reaches 1.5-2 atm, filling the system will need to be stopped. In principle, the operating pressure of a boiler may vary depending on the manufacturer and model - therefore, see the instructions for the boiler for the exact operating pressure.

Peculiarities

Gas boilers made in Italy by Ariston are presented in a wide variety of models, however, regardless of the modification, the equipment of this brand is aimed at installing heating systems on an area of ​​no more than 500 m2. Some boiler options only work for heating, while others are used not only to supply heat to the house, but also to supply hot water.

Speaking about the essential options for gas boilers from this manufacturer, we can highlight the following characteristics.

• The presence of a multilingual menu - this allows users to choose a language familiar to them to effectively control the operation of the boiler.
• The “auto” function makes it possible to configure the required power parameters in autonomous mode based on monitoring the actual temperature in the room, as well as inside the boiler.
• Heat and noise insulation - ensures silent operation of the equipment, and in addition helps to maintain the coolant at a given temperature for a long time even after stopping work.
• The warranty on all of our equipment is 2 years for standard boilers, and longer for condensing models - for 3 years.
• Ease and ease of use - the menu is thought out very competently, thanks to which even beginners who have not yet dealt with gas installations can effectively operate the boiler.
• A safety system that prevents breakdowns caused by power outages.
• Built-in electrified elements that maintain the operation and performance of the unit even in conditions of low water or fuel pressure.

A characteristic feature of all Ariston models is a well-thought-out and highly technological protection system, which ensures long-term and uninterrupted operation of the gas installation.

It includes:

• mechanisms for replenishing the boiler with water;
• built-in system for timely pumping out accumulated air;
• blocking the circulation pump;
• anti-scale and anti-freeze protection mechanism.

Common parameters of all Ariston models include small dimensions and the ability to supply hot water. The basic package includes: a double-type heat exchanger, a burner control module, a carbon monoxide control system, a mechanism for maintaining a normal indoor microclimate, and a device responsible for controlling the freezing of water inside the heating system.

The lineup

The line of models of double-circuit boilers, in contrast to single-circuit boilers, is more in demand, since the models are designed for heating rooms and supplying hot water.

BCS 24 FF (closed combustion chamber) and Uno 24 FF (open combustion chamber)

Most buyers choose Ariston of these brands.

In addition to the operating instructions, the device comes with all the elements of the heating system, which you can operate every day and without special skills.

All information can be read on the display.

Distinctive abilities

According to reviews of Ariston gas wall-mounted double-circuit boilers, they have 4 distinctive features that are useful for their owners:

1. All models of this company are equipped with automatic protection systems.
2. The presence of a water pump, which is necessary for constant circulation of water through the pipes.
3. Possibility to choose a model with an expansion tank. With its help, pressure will be automatically adjusted inside the heating system.
4. Ariston equips its equipment with various types of ignition. It can be automatic, which will make life much easier for the owner of a particular boiler. Otherwise, every time the unit starts, the person will need to press a special button.

Technical characteristics of Ariston gas boilers

All boilers of this brand have a power of 15 to 30 kW. You can choose exactly the power that suits the size of your house or apartment.

So, the technical features of wall-mounted heating units:

• It’s very good that the menu of wall-mounted boilers for Russian citizens is also in Russian. Therefore, you can easily set the temperature that should be;
• in places where power surges often occur, these Ariston heating devices are best suited. They can withstand them without problems;
• Gas units also cope well with reduced gas and water in systems.
• gas double-circuit units are easy to operate. They are also easy to install, so even a novice in this matter can handle it.
• they have a high level of efficiency and are quite economical.

Of course, there is the possibility that the boiler will not be able to heat the heating system and water at the same time, but this is not a big problem. Since, if necessary, you can install a boiler in parallel to heat water.

Some models of gas wall equipment may even have sensors that detect indoor and outdoor air temperatures, so they work even more efficiently. The built-in display will show all the parameters by which the unit operates, so you can correct everything in time.

Boiler service menu

For all manipulations with switching modes, only 4 buttons are used - Plus, Minus, Ok/Menu, ESC.

It is important to understand that not all boiler menu items will be available to you; some of them will only become available when additional devices are connected to the boiler, such as external sensors or a solar collector. And most menu items are accessible only by service code, I’ll talk about this below, but for now let’s “practice on cats”

Reviews of Ariston double-circuit wall-mounted boilers

The manufacturer of gas boilers Ariston has taken a leading position in the market due to the quality of its units. This is evidenced by many customer reviews throughout Russia:

Ariston gas boilers made in Italy are popular due to their uninterrupted and quiet operation. They include many models with different characteristics. Let's take a closer look at the design of the Ariston gas boiler.

Model operating instructions

You can also choose an Ariston boiler as a heating equipment; the operating instructions are included in the kit and must be studied by you before you start using the equipment. In it, the manufacturer discloses safety issues

For example, it is important to prevent leakage of liquid gas, as this can pose a danger to human life. If this does happen, then the heating system must be turned off.

The premises should be checked by closing all doors leading to living rooms. It is prohibited to use electrical switches.

If you smell gas, a leak could cause an explosion. Smoking is prohibited under such conditions.

It is important to eliminate the possibility of sparks and open fire. You need to immediately open the windows and turn off the gas supply

The heating system must be turned off. People should not be allowed into the danger zone.

The Ariston boiler, the operating instructions for which you must read if you have purchased such equipment, is installed taking into account the manufacturer’s recommendations. After reading them, you can find out that the device is mounted on a vertical flat surface. For ease of maintenance, minimum clearances should be ensured. No special ventilation is required in the room where the device is installed.

When connecting gas, make sure that the connections are tight. Electrical wiring should be connected in such a way as to facilitate electrical isolation of the equipment. Before applying water, flush the system without disconnecting the device. In order to remove contaminants and prevent damage to the heat exchanger, you should make sure that there are no contaminants, as they can cause build-up and corrosion.

Causes of malfunctions

In most cases, the cause of breakdown is violation of the rules in the operating manual. The main mistakes when using Ariston hotpoint refrigerators are as follows:

1. The door remains open for a long time - to prevent this situation, refrigerators are equipped with a sound signal that beeps and warns of the need to close the door, but most owners ignore this “request” of the refrigerator.
2. Often the door remains loosely closed due to incorrect placement of dishes and food on the shelves of the unit.
3. Dishes that have not yet cooled down are sent to the refrigerator.
4. When using a model with periodic defrosting, the manufacturer's recommendations regarding timing are not followed - icing occurs on certain components of the unit, which often leads to failure of the refrigeration equipment.

The electronic control system helps check the functioning of the unit, signals malfunctions, and if defects are eliminated in a timely manner, the operating period increases noticeably.

Error d, displayed on the screen, indicates a failure to open the valves. When the unit was released in 2012, this problem is global and applies to all refrigerators of that year. At home, it is impossible to eliminate the problem on your own, since this is a “development defect” that can only be solved in a service center. The problem is that the top door has a plastic gasket at the bottom that wears out when the door is opened and closed frequently. It is only possible to smooth out the depth of the problem a little on your own by cutting out a gasket from rubber to replace this plastic - in order to lift the sash. But not all models can carry out such repairs.

Correct maintenance of the device

The fact that problems have arisen in the operation of the device may be indicated by some changes in its operating mode. For example:

• increasing the time for heating water to a given temperature;
• the appearance of unusual sounds accompanying the operation of the device;
• the appearance of foreign impurities in tap water, changes in its color, smell or taste.

If at least one of these signs is observed, you should immediately clean the water heater. To do this you will have to perform the following operations:

1. Disconnect the device from the power supply.
2. Remove the protective cover.
3. Disconnect the contacts of the electrical wires.
4. Shut off the cold water supply.
5. Use a hose to remove any remaining water from the tank.
6. Unscrew the bolts that hold the heating element.
7. Remove the heating element and descale it.
8. Clean the inside of the drive from dirt and scale particles.
9. Rinse the device thoroughly.
10. Check the serviceability of the magnesium anode.
11. If necessary, replace this element immediately.
12. Wait for the cleaned tank to dry completely.
13. Reinstall the heating element.
14. Reassemble the device.
15. Check the reliability of all fastenings.
16. Connect the water heater to the power supply.
17. Check for grounding.

The heating element should be removed from the tank carefully; the bolts may be too stubborn; sometimes the heating element is difficult to remove due to too much scale. The heating element is cleaned by mechanical or chemical means, as is the removal of contaminants from the tank. If a large amount of scale is found inside the device, you should consider reviewing the operating mode of the water heater.

This phenomenon is often observed when the device operates at maximum power for a long time. It is recommended to set the maximum heating temperature no higher than 60 degrees to increase the life of the device and reduce the number of breakdowns. If the body of the heating device receives an electric current, the heating element may be deformed and ruptured, or there may be a breakdown in the control system.
