Wall-mounted gas boilers Ariston - the main types of devices and their functional features
Today we will get acquainted with the brand, which has long been heard by the Russian buyer. The topic of our article is heating gas boilers Ariston and other products of this manufacturer. Of course, we will try to learn more about the manufacturer himself.
About the manufacturer
Its history began in 1930. A certain Aristede Merloni founded a small company for the production of scales in the Italian city of Fabriano. Later in its range were added gas cylinders and electric water heaters.
The production successfully survived the rise to power of the National Socialists and the fall of their regime, the war and the bombing. During one of them, the plant was badly damaged and was restored after the end of hostilities.
The Ariston brand was born in the sixties. The word literally translates from Greek as "the best."
It is curious: in addition, its sound clearly echoes the name of the creator.
After Aristede's death, the company's assets were divided among his three sons. We are interested in Vittorio, who lost the right to the brand. Despite the fact that the European market had long been divided between large manufacturers by the end of the seventies, Merloni Elettrodomestic, managed by Vittorio, achieved incredible success:
- 1989 - The company acquires the extremely popular Indesit brand.
- 1990 - Schulthess becomes another brand under which products are made.
- 2000 - the company buys out the assets of the Novolipetsk plant Stinol, which produced refrigeration equipment. The plant did not recover from the 1998 crisis; after selling to the Italians, he began to produce refrigerators under the names Indesit and Ariston.
- In 2007, the previously purchased British brand was merged with the Italian one. From now on, household appliances are produced under the Hotpoint-Ariston name.
- The current price of Indesit Company is approximately $2.5 billion. It is one of the largest manufacturers household appliances and heating equipment in Europe.
Range
Heating and hot water equipment is far from a priority area for the company. It was not affected by the rebranding of 2007: all products are still manufactured under the brand name Ariston.
What is in the assortment of the company?
- Traditional Ariston. On the Russian website of the company, the buyer is offered 9 lines. We will return to their features and characteristics.
- Floor gas boilers are represented by one line at all.
- Boilers of indirect heating, a significant part of which can be used as heat accumulators in heating systems. Here the company offers 8 lines of devices.
- Solar heating systems. They are represented by 11 positions, and both individual collectors and complex solutions are offered.
- If you remember, one of the first product lines in pre-war Italy was electric water heaters. The current Ariston does not change traditions: in its assortment there are 34 devices using electric heating elements or gas-burners. Of course, both flow and storage heaters are presented.
Useful: a common problem with all flow gas heaters is the unstable temperature of hot water. The burner continuously adjusts to the current water flow, which you have to constantly adjust. As a result, an attempt to take a shower begins with a ten-minute unequal struggle with the faucet.
- Condensing boilers complete the list of products - 7 lines of different power and functionality.
heating equipment
Since the topic of our article is gas heating boilers Ariston, let's dwell on this part of the product range in more detail. What is offered to us?
Traditional
Genius EVO
The line includes two models with a capacity of 24 and 30 kilowatts with open burners. Ignition - electronic, efficiency fluctuates around 90% depending on temperature regime. The boilers are double-circuit, with the output of hot water at a temperature of 35C at 10.2 and 11.3 liters per minute.
The devices are equipped with a safety group including an 8-liter expansion tank, and a circulation pump with stepless speed control.
CLAS EVO
This line largely repeats the previous one. It has three wall-mounted double-circuit devices with a capacity of 24 and 28 kilowatts. The efficiency has slightly grown and is 91-93%.
Curiously, the 24CF is equipped with atmospheric burner, and 24FF and 28FF are turbocharged and divert combustion products to the street. Their temperature, by the way, does not exceed 118C.
CLAS EVO SYSTEM
A wider choice of power is presented here: models from 15 to 32 kilowatts with open and closed burners. Single-circuit boilers; circulating pumps lost their smooth adjustment and became two-speed.
A curious feature (present, however, in other EVOs) is self-diagnosis with logging of accidents.
In the photo - CLAS EVO SYSTEM.
CLAS SYSTEM
Budget line without any frills. The younger model is 15 kilowatts, the older one is 32. Burners are open and closed type; The efficiency in all models is above 90%.
Boilers, of course, single-circuit. However, it is possible to connect an indirect heating boiler, like any other heating device.
Curious: when connected, the manufacturer promises a capacity of more than 1000 liters of hot water per hour. Without mentioning, however, for which particular model.
GENUS
There is confusion associated with this line that only the manufacturer can probably explain.
Genius boilers are positioned as extremely economical and easy to use. There are three models in the line - 24, 30 and 35 kW. Of course, with a safety group made of heavy-duty composites, ultra-precise temperature sensors and the ability to connect a programmer.
Curiously, both the pump and the burner pressure can be adjusted steplessly. Heat-resistant stainless steel burner and heat exchangers are also a nice bonus. Finally, the boiler can smoothly regulate the power of heating work with a constant power for water supply.
But! It is positioned as traditional and is in the appropriate section. However, the temperature of the combustion products does not exceed 65C, and the efficiency in economy mode (at 30C on the return line) is 108%, which clearly indicates a condensing type boiler.
Well, let's write it off for inattention ...
CLAS
Another line of the class "economy". Double-circuit boiler with a minimum set of service functions, but a separate heat exchanger. Burners - open and closed type, power - 24 and 28 kW.
The manufacturer specifically mentions "adaptation for Russian conditions." Translated from the diplomatic language of the official website, sadly, this means “it is difficult to break even with the grossest violation of operating standards” ...
Please note: just in case, we recall that you can connect any gas equipment by hand is strictly prohibited. Actually, this is clearly stated in the instructions for any boiler. You will have to turn to the services of the gas service.
EGIS Plus
Before us is a line of compact and not too heavy wall-mounted boilers of quite acceptable power of 24 kilowatts. There are options with open and closed burners; both models are equipped with separate heat exchangers.
BSII
Economy class, equipped, however, with all the useful features of older models. The design is perhaps somewhat inexpressive. Otherwise, decent devices with open and closed burners with a capacity of 14 - 24 kW.
It is curious that in the older model with a closed burner, the efficiency reaches 94%, which is very high for a device that uses the lowest calorific value.
CLAS B
The highlight is the 40 liter built-in stainless steel boiler. After mixing with cold water he is ready to give 80 liters with a temperature of 40C. In addition, if the water from the boiler is used up, then from 24 to 30 kilowatts of thermal energy of the burner will go to work for the needs of hot water in the flow mode.

Air supply and removal of combustion products
The Ariston Egis Plus 24 ff boiler allows installation of type B (air supply from the room) and type C (air supply from outside).
Install the seals carefully in accordance with this manual to prevent combustion products from entering the duct system.
When installing the combustion products removal system, be careful not to break the seals and prevent combustion products from entering the air duct.
Horizontal sections of pipelines must have a slope of at least 3% to prevent the accumulation of condensate.
Type B installation is permitted in rooms with adequate ventilation and air supply, in accordance with current codes and regulations.
In rooms where there may be corrosive vapors in the air (eg laundries, hairdressers, galvanizing stations, etc.) only a type C unit (with air supply from outside the room) should be used. This protects the boiler from corrosion.
When installing a coaxial (double) flue/air supply system, only original accessories must be used.
The chimney must not come into contact with or pass in close proximity to flammable materials, nor should it pass through building structures made using flammable materials.
The connection must be made in such a way as to ensure that condensate does not enter the boiler.
When replacing an old boiler, the elements of the ventilation system and the removal of combustion products should also be replaced.
Chimney/air duct connection
Coaxial system (of the "pipe in pipe" type), designed to supply air and exhaust combustion products;
Separate system for the removal of combustion products and air supply from outside the room;
Single-channel chimney for removing combustion products, air is supplied from the room.
When connecting the Ariston Egis Plus 24 ff boiler with a chimney / air duct, only materials and components that are resistant to condensate may be used.
For information on the lengths and orientation of the connecting elements, see the table "Types and lengths of pipelines for the supply of air and removal of combustion products."
Accessory kits for connecting the chimney / air duct are not included in the boiler delivery set, they must be ordered for a specific type of connection.
All Ariston boilers Egis Plus 24 ff are designed for air supply and exhaust of combustion products through a coaxial system with a diameter of 60/100 mm or a separate system with a diameter of 80/80.
In the case of pressure losses in the piping, additional aerodynamic resistance must be taken into account when sizing the chimney/air duct (see catalog of chimney/air duct accessories).
Make sure that the air supply and combustion products exhaust pipes are free from foreign objects and have no leaks.
To connect a separate system, use only one of the two air inlets. Loosen the screw, remove the plug, install the air intake insert and secure with the supplied screw.
Connection gas boiler Ariston Egis Plus 24 ff to the electrical network
In order to ensure safety, have a qualified person carefully check all electrical connections of the boiler.
The manufacturer is not responsible for damage caused by lack of proper grounding or improper parameters of the power supply network.
Make sure the system is sized for the maximum power drawn by the boiler (see rating plate). Ensure that conductors with a cross section of at least 0.75 mm2 are used.
For proper and safe operation, the boiler MUST be securely grounded.
Power is supplied from the mains 230 V, 50 Hz (L, N + PE) with polarity and a grounding conductor.
If you need to replace the power cable, contact a qualified technician. The ground wire (yellow or green) must be longer than the live wire or neutral.
The connection of the Ariston Egis Plus 24 ff boiler to the power supply network should be carried out through a permanent connection (the use of a plug is not allowed) through a two-pole switch with a minimum distance between contacts of at least 3 mm.
It is strictly forbidden to use multi-pin plugs, extension cords and/or adapters. The boiler does not have lightning protection devices.
If fuses need to be replaced, use 2A fast blow fuses.

OPERATION AND REPAIR OF BOILERSUpdated:
2016-09-01The Ariston boiler is a high-quality Italian product. The Ariston boiler is protected from power surges and can work even with low temperatures down to -52 degrees.
Ariston boilers represent nine different lines of models, in each of them from 2 to 7 models maximum, they differ not only in power and efficiency characteristics, but also in price. This group of models has single-circuit boilers and double circuit. Boilers are produced both in a wide and in a narrow range of capacities.
However, despite the power, all models have automated system controls and can also be used with a conventional chimney, and can also be used with a coaxial chimney. The control panel in some models may differ, but in each unit it is Russified and has a clear logical system, which allows the user not to refer to the instructions for every question. Each Ariston unit has the following elements, functions and characteristics:
- There is an economical burner made of stainless steel, the operation of which is fully controlled depending on the desired result.
- Function of diagnosing problems. Some models even have a list of possible faults.
- Manufactured from composite materials with increased strength, a group of various hydraulic devices.
- Expansion tank with a capacity of 8 liters.
- Automatic removal of excess air.
- Protection against internal scale, freezing of the boiler, as well as blocking.
- The double-circuit unit is endowed with a primary heat exchanger, which is made of copper with an additional protective layer to increase durability, and the secondary heat exchanger is made of stainless steel.
- In double-circuit models with the function of preparing water, only its heating is possible.
- Excess condensate collection system.
- From two to four temperature sensors built into the boiler.
Boiler difference
The double-circuit wall-mounted boiler is the most popular among consumers. This popularity is due to some of the qualities that these boilers have. The main ones are ease of installation, small size with the possibility of embedding in a wall cabinet.
The less popular Ariston floor-standing gas boilers do not have a special weight limit and are made from thick metal parts, due to which the power of such models is noticeably greater, which cannot be said about the wall-mounted version. Double-circuit floor-standing boilers only work to heat water, which acts as a heat carrier, to heat the liquid in the storage tank. Single-circuit floor, unlike counterparts, it has more power and, accordingly, efficiency. Below you will find detailed description to some of the models that are in particular demand.
GENUS EVO line
The Ariston double-circuit unit is equipped with exclusively open combustion chambers with the 3rd class of fuel combustion efficiency and economy. Automation built into the boiler allows you to fully control its operation based on the weather outside. It is also possible to attach a touch control panel and connect it to a solar collector with efficient use of heat. There is also a fan and a pump.

DHW operation at 35 degrees is 24CF - 11.2 liters / min and 30CF - 11.3 liters / min. This line represents the category of conventional, traditional boilers. The price of this model of boilers varies in the range - 50,000-60,000 thousand rubles.
Model GENUS
Double-circuit boilers of this Ariston model are equipped with a burner with a closed combustion chamber. They have an increased, 4th class of energy efficiency. The automatic control system will independently adjust the operation based on the weather conditions outdoors and indoors. There is also automatic system make-up and a special sensor that checks the water pressure.
Despite the fact that this type of boiler is on the list of conventional boilers, the functionality has condensation technology, thanks to which it is possible to reduce gas consumption by 35% with an efficiency of 107%. In this line there are three variants of models 24FF, 30FF and 35FF with the highest power 24FF - 22kW, 30FF - 28kW and 35FF - 31kW, and the smallest 24FF - 5.5kW, 30FF - 6.7kW and 35FF - 7kW with a performance at 35 degrees is 24FF - 10.3 liters / min, 30FF - 12.9 liters / min and 35FF - 14.3 liters / min.
CLAS EVO
Wall-mounted boiler Ariston CLAS EVO, similar to the GENUS EVO model. It differs only in that in this line there are units with both methods of combustion with closed chambers (24CF, which is wall-mounted) and open (24FF and 30FF). The efficiency of a unit with a closed one is 91-92%, and for models with an open one it is 93%.
The 24CF has a capacity of 10.2 liters/min, while the 24FF and 30FF have 9.9 liters/min and 11.6 liters/min. The value of the double-circuit model CLAS EVO is 40,000-50,000 thousand rubles.
Boilers CLAS EVO SYSTEM
This Ariston boiler has a post-circulation mode, a copper heat exchanger, an automatic weather-dependent system, as well as the possibility of connecting to a solar collector and any possible control system.
As in the model that you read about earlier, this model has units not only with a closed combustion chamber, namely 15FF, 24FF, 28FF, 32FF, but also with an open chamber - 15CF, 24CF and 28CF, with maximum power boiler from 16.5 kW and up to 32.5 kW, depending on the model and the minimum, respectively, from 8.5 kW to 14 kW. The efficiency with a closed chamber is from 91 to 93%, and with an open chamber - 90%. The price of these gas boilers will be in the range from 35,000 to 43,000 thousand rubles.
CLAS SYSTEM
The wall-mounted, single-circuit boiler Ariston CLAS SYSTEM can be with an open combustion chamber (CF) and a closed one (FF) with a power of 15,24,28 and 32 kW. For boilers with closed system 93.5-95%, and with open 90-92%, with power from 16.5 kW to 32.5 kW, and minimum - from 7.3 kW to 14 kW.
EGIS PLUS Compact economical line Ariston, which has a fairly small size and significantly light weight of 30 kg. There is an option with an open combustion chamber and a closed one, but, despite the difference, they have the same power - 24 kW. However, the efficiency of a boiler with a closed combustion chamber is 94%, and with an open one - 92%. The productivity of these boilers is 9.7 liters / min. The price of boilers of the CLAS SYSTEM model can vary from 37,000 to 45,000 thousand rubles.
CLAS B
One of the interesting models of Ariston is the CLAS B unit. It has a 40-liter boiler built into the boiler, which takes only 10 minutes to heat the water. After using heated water, warm water continues to flow to you warmed up. Another feature is that these boilers are wall-mounted.
There are 3 options in this line 24CF, 24FF, 30FF, and there are only two capacities - 24kW and 30kW. As for the price, wall boilers of this line are one of the most expensive firms Ariston and is about - 70-80 thousand rubles.
How to make a choice?
But how to choose the right Ariston gas boiler? To do this, you need to decide on some points, namely: first of all, what type of connection is right for you, you need to find out how much you are willing to pay for the boiler.
It is important to decide which boiler you need single-circuit or double-circuit, choose between wall-mounted and floor standing boilers and finally, you need to choose a boiler with a control system that is convenient and suitable for you. Everything else regarding the connection and installation of the Ariston boiler is not difficult and not expensive.
