How does an Ariston gas boiler work?

Double-circuit gas appliances make our lives more comfortable and enjoyable. They are quite practical to use, suitable for heating country houses and small apartments. They are used for heating industrial or warehouse buildings with an area of no more than 500 sq.m.

The advantages of Ariston boilers are that in addition to heating buildings in winter, they heat water used in everyday life all year round. This is quite convenient and does not require the installation of additional equipment.

General characteristics of Ariston boilers

The description of Ariston gas units must begin with the characteristics of their main part - the burner. This element is used to burn fuel and release thermal energy into the heating system.

Types of boiler burner:

The modulation burner is more convenient to use. It provides automatic power control depending on the temperature of the device.

According to the type of exhaust of combustion products, burners are divided into:

closed type
open type

Units with a closed burner are safer to use. In this case, natural gas combustion products do not enter the room. The use of a chimney is not required. A coaxial pipe is simply connected to the device and taken out.

Equipment with an open burner requires the use of a chimney to remove combustion products.

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.

Characteristics of Ariston boiler models

A distinctive feature of Ariston boilers is their high quality. After all, the name of the company is translated from Greek as “the best.”

Its products are especially popular among middle-income consumers. Gas boilers of this brand are purchased for heating rooms up to 500 sq. m. The company's products are universal. The transition to liquefied fuel is carried out only by replacing the burner.

All boiler modifications have in common:

small size.
supply of hot water, in the absence of a centralized supply.

Gas boilers of different modifications differ in structure; what they have in common is their low cost and high-quality parts.

Basic equipment of units from Ariston:

double heat exchanger.
electronic gas burner control module.
carbon monoxide control.
microclimate support in a building or in a separate apartment.
control of water freezing inside the system.

Let's take a closer look at existing types of Ariston equipment.

Ariston Genus

Available with double heat exchanger. All modifications are double-circuit and wall-mounted.
This model is considered the most functional of all Ariston devices. Has an LCD display and a button control panel. Ariston Genus can be configured to work autonomously for a whole week.
The display shows basic data on the status of the device and a list of possible errors. The burner is modulating, that is, completely controlled electronically. This function increases the comfort of using this model of gas appliance, due to minimal control by the consumer.

The Ariston Genus line includes the Evo and the more expensive Premium models.

The Evo model is a dual-circuit gas appliance with both types of burner: open and closed.

Genus Premium condensing boilers. They are used for heating residential and commercial buildings. Power range from 24 kW to 35 kW.

Ariston Clas

The device is small in size.
This is a boiler with two circuits and an elegant appearance. The reduced dimensions did not impair its functionality in any way.
Expansion tank 8 l. Hot water heats up quickly

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.

Choosing a gas appliance for heating

Ariston products can be found in catalogs. There are many models of gas appliances available there. The main mistakes when choosing the wrong unit are made from a lack of information. Therefore, before visiting the store, you should familiarize yourself with the basic tips for choosing a wall-mounted gas appliance.

When choosing a boiler, consider the following points:

The size of the kitchen as the place where the heating device is most often installed. In the store, the choice begins by considering the overall dimensions of the device and selecting it individually for your kitchen.
Next, move on to the technical data and study the type of water heater in the device. If there are a large number of people in the family, then it is not recommended to purchase a boiler with an instantaneous water heater.
In this case, it is more rational to purchase a boiler with a storage tank for hot water and select equipment for the amount of water that you will need for everyday use.
Evaluate the combustion chamber of gas equipment. It can be closed or open. It is recommended to choose a boiler with a closed chamber because it is safer to use. The presence of a chimney is not necessary, which is important in multi-storey buildings. All you have to do is buy a coaxial pipe and put it outside.

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.

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.

Descriptions of the Ariston double-circuit boiler

Today you can find many interesting models on the gas boiler market. This is quite convenient, since everyone can choose the device that is most suitable in terms of price, type, characteristics and installation method. Ariston double-circuit wall-mounted boilers gained their popularity due to rare situations with their malfunction, as well as silence during operation, which is very important for maintaining a calm environment in the house.

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:

The safest is a closed system, 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.

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

Distinctive abilities

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

All models of this company are equipped with automatic protection systems.
The presence of a water pump, which is necessary for constant circulation of water through the pipes.
Possibility to choose a model with an expansion tank. With its help, pressure will be automatically adjusted inside the heating system.
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.

What are the advantages of Ariston gas boilers

Recently, the popularity of the Ariston brand has increased significantly due to high-quality gas boilers, and this is not in vain. Double-circuit equipment operates silently and consumes fuel in the smallest quantities possible. This will allow the owners of the unit to save on utility bills and, at the same time, provide comfort and warmth to the home.

The client will receive a high-quality device that provides round-the-clock water supply and heating to the house, even with a large area of up to 500 square meters. Also, do not forget about the longevity of each boiler. The periods specified in the guarantee are much more modest than they actually turn out to be. The dimensions of the equipment are much more compact than those of other brands, which means that it can be installed absolutely anywhere, even in a small apartment with limited space.

Tables with three-digit codes, descriptions and set values

The values added in the white fields are the values used in my boiler. If there are no corrections, then I have the same values as those printed in the table. To enlarge, click on the photo of the table.

Do you want to install individual heating in your home? Have you already installed and connected gas equipment? Great, then all that remains is to figure out how to turn on the gas boiler. Do you think it’s enough to insert the plug into the socket and select the temperature? No matter how it is. Before this, it is necessary to bleed the air and fill the system with water. You will find instructions with the sequence of actions in our article.

Specifications

Almost all gas boilers from the Ariston brand have a power of 15 to 30 kW. Thus, each client will be able to select the necessary indicators for the size of their apartment or house. It is also worth noting other distinctive characteristics of such gas equipment:

at maximum efficiency, boilers have a high level of efficiency;
all wall-mounted boilers have Russian instructions and symbols on the equipment itself, so citizens do not have problems with operating the unit;
most models from this manufacturer are able to cope perfectly with water in the system and low pressure;
Particular attention to this equipment should be given to those people in whose homes voltage surges often occur. Ariston boilers cope with such network surges without any problems;
All models are very easy to operate. To start using the boiler, you don’t need to study the instructions for a long time; all operating features are intuitive and accessible even to those who are installing such a unit for the first time.

In some cases, the boiler cannot simultaneously heat water and provide sufficient heating of the room; this applies to budget models. In this case, a person needs to think about installing an additional boiler.

Note! If we talk about expensive units, they have a special display that displays various characteristics, including the temperature inside and outside the boiler. This is very convenient in terms of entering the necessary characteristics for the correct operation of the equipment.

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 installing the gas boiler, you need to have a conversation with them and explain in clear 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.

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.

What types of Ariston wall-mounted boilers are there?

All Ariston boilers are divided into 3 series. They have different technical indicators and functions, namely:

Clas - this series refers to more bulky and powerful devices for heating residential premises. They are equipped exclusively with special regulators that automatically regulate the gas supply. This is necessary to save fuel, which is very convenient in terms of utility costs and for frequent business trips of the home owner.
Genus. These are the most innovative and multifunctional models of Ariston gas units. They have more features than other boilers from this manufacturer. Along with the equipment itself, the buyer will receive additional accessories such as a fan necessary for smooth speed control, as well as heat exchangers, primary and secondary. All devices from the Genus line are distinguished by the presence of a large liquid crystal display. It will display all the characteristics that correspond to the operation of the boiler at the moment.
Egis. The units from this series are small in size and attractive in appearance, which is why they have earned great popularity among owners of small apartments. The device will fit well into any interior. An important feature of these boilers is that, given their size, they have a fairly high level of efficiency and low fuel consumption, which is controlled by an intelligent control system.
