About company
The Ariston brand is the brainchild of Vittorio Merloni. His father, Aristide, founded a small business back in the 30s of the last century. Today, this enterprise has become the largest industrial giant, uniting several large companies. Concern Merloni Elettrodomestici in 2005 was renamed Indesit Company, which includes several brands, including Ariston. The company ranks third in the world in terms of sales of household appliances.
Advantages and disadvantages
Italian boilers are able to operate smoothly even at a pressure of 5 mbar and at a temperature of minus 52 ° C. They are equipped with two mechanical filters that purify the water. The developers took into account almost all the dangers for gas equipment in high-risk conditions.
Each model is equipped with a self-diagnosis system that simplifies their operation and maintenance. Security systems prevent emergencies by stopping the operation of the device in a timely manner. Self-diagnosis is periodically repeated - if the parameters are normal, the device will start without human assistance. Pros of Ariston:
- Absolute safety - despite explosive fuels.
- High efficiency. After the combustion of the gas, almost no combustion products remain - all the heating goes to heating.
Minuses:
- Floor standing equipment should be located in a separate room.
- To eliminate pressure surges, an additional adjustment unit has to be installed.
General advantages of double-circuit gas boilers
The main advantages of double-circuit gas boilers are concentrated on four functional levels:
- In the gas system
- In hydraulics
- In the implementation of temperature control over heating
- In a system that controls the control of operating modes and fire and explosion safety.
The gas system of the Baxi, Ariston and Fondital boilers has the following features:
- heating and hot water supply mode occurs with constant modulation of the flame level in the gas burner;
- it is allowed to reconfigure the fuel supply from main to liquefied gas;
- to avoid corrosion, only stainless steel is used in the manufacture of the burner.
What do Ariston products have in common?
Traditional gas heaters are available in nine lines - each of them contains a different number of modifications - from 2 to 7. The lines are single-circuit and double-circuit versions. Some have a wide range of capacities, others consist of 2-3 options. All traditional Ariston models are distinguished by the following features:
• Automatic control. All modifications have the "auto" function - the intelligent unit selects the optimal modes by itself, taking into account changing conditions.
• Can work with a conventional or coaxial chimney.
• Russified control panel. Its logic is intuitive - you don't even need an instruction manual to figure it out.
• Burner material - stainless steel. Its power is modulated taking into account the given mode. This solution saves gas.
• Self-diagnosis.
• Hydraulic devices are made of high-strength composite materials.
• Expansion tank - 8 liters.
• Automatic removal of air from the heating system.
• Protective systems - from blocking, scale, freezing.
• The double-circuit device has a copper heat exchanger - primary, and from a stainless steel - secondary, for heating domestic water.
• In 2-circuit versions, a "summer" mode is provided - operation only on hot water supply.
• Condensate container.
• Temperature sensors - 2-4 pieces, depending on the series.
• High quality sound insulation. Virtually silent operation.
• Included - instruction manual.All documentation is presented in Russian.
• Warranty - 2 years. For condensing versions - 3 years.
• Average dimensions 70x42x60 cm - this is slightly larger than that of competitors.
The models of each line have distinctive design and technical solutions. Also, models may differ in functionality, dimensions, design.
What else is worth saying about 2-circuit boilers
You've probably noticed that a lot depends on the manufacturer, but it's worth mentioning a few general points. For example, an expansion tank is required to regulate the pressure in a closed system. Of course, more modern boilers are equipped with sensors (pressure gauges), which transmit a signal to a control element at critical pressure values. The latter blocks operation until water is drained from the system. Another important point is the control system with which double-circuit gas heating boilers are equipped. Reviews indicate that a remote control system is more preferable, since it is more accurate and helps to save gas. Most boilers today are equipped with a self-diagnosis function. The unit will independently find any deviations from normal operation and signal you about it. But not all devices are equipped with such systems, a vivid example of this is the Buderus double-circuit gas boiler. Reviews, however, are good about it, due to the high build quality.
What are they?
By installation method:
- Wall-mounted - it is compact, has a copper heat exchanger (less often - steel). It is completed with strapping elements. Mounted on a flat wall. Mounted models are more sensitive to unstable parameters of gas and water supply.
- Floor standing units are more powerful, heavier and larger in size. They need a large enough area. They are mounted on the floor - on a stand. Manufacturing material - cast iron. Power - up to 64,000 watts. This heating capacity is enough to heat an area of up to 500 square meters.
By the number of contours:
- Single-circuit - they work only for heating the room.
- Double-circuit - heats the house and heats water for domestic use.
By the type of combustion chamber and thrust:
- Open firebox (natural draft) - combustion air comes from the room. Such a device is atmospheric.
- Closed chamber (forced draft) - the principle of operation is based on forced ventilation. This is a turbocharged version.
Ariston boiler designs
Ariston wall-hung boilers can be equipped with atmospheric or modulating burners. The second option is more common, as it is more convenient and has automatic adjustment. Also, the units are equipped with an open or closed burner. The closed type is preferable, since it excludes the ingress of combustion products into the room air. For units with an open burner, you will have to arrange a well-ventilated specially equipped room - a boiler room and connect a classic chimney.

Overview of wall-mounted gas boilers
The Ariston range of heating units includes single and double-circuit devices. The latter will be able to provide you not only with heating, but also with hot water. Ariston wall-mounted double-circuit gas boiler has two heat exchangers. On sale you can find models with both separate and duometric (combined) heat exchangers. It is also possible to have a built-in water heater.
Gas boilers of this manufacturer also differ in the type of ignition: piezo ignition or automatic. The second option allows you to start the unit by pressing one button.

All models of Ariston wall-mounted gas boilers have protection and automation systems with certain capabilities.
How to choose?
To choose gas equipment for heating a private house or apartment, you cannot act intuitively - you need a calculation of heat loss. For the calculation, the condition is taken that for 10 sq.m. area (height up to 3 m) should have 1000 watts. But this is just a rough estimate. It is not recommended to select an option without a margin, so that the device does not have to operate at the maximum of its resources. It is also necessary to take into account the degree of insulation of the house.
A more accurate calculation is ordered by construction and design companies. The cost of such services depends on the region and is 2,000-7,000 rubles. Calculation errors can provoke:
• uneven distribution of heat in rooms;
• shortage of hot water.
Operation and maintenance
You should find out from the instructions what the pressure in the expansion tank should be - as it may drop during operation. It is recommended to check the pressure once a year. Periodically follows:
• check filters, if necessary - clean;
• cleaning the heat exchangers - this is especially important for hard water;
• change the corresponding gaskets.
The above activities, as well as installation, configuration and first start-up are the task of the service technicians. The owner only needs to conclude an appropriate service agreement and follow the manufacturer's recommendations regarding the operation of the device. A specialist should be called twice a year - you cannot start the heating season without an inspection. At the end of the season, you also need to invite a service worker.

In general, Ariston boilers fail quite rarely. Even if this happens, most of the parts are in stock at the service centers. But for stable operation without interruptions, good traction, correct shape and power supply is required within the required limits. Additional filters at the water and gas inlet will not interfere, although the boilers have built-in ones. The installation and start-up of the boiler in order to maintain the warranty obligations must be carried out by employees of a service center certified by the company. Although, according to the experience of most owners, there are no problems within 5 years after purchase. At this point, how lucky is anyone. And so that later there are no controversial issues, carefully read the documents and operating instructions, and only then act.
Start-up and operation
Commissioning works are carried out by the company representatives - service workers.Failure to comply with this requirement will result in a denial of warranty. The user just needs to read the instructions to figure out how to use the device. It is important to follow the operating rules and to perform seasonal maintenance on time. In the event of a malfunction, an error code appears on the display indicating the cause of the malfunction or the problem that has occurred. Complete with gas equipment - instruction, passport and connection diagram.
How to fix?
When installing, you need to take into account the following points:
- Anchor bolts are used for fastening. Installed on any wall - blank or load-bearing. Wall material - brick, aerated concrete blocks, reinforced concrete slabs.
- The piping is carried out according to the instructions. The data sheet describes in detail the purpose of all conclusions. Cut-off valves are placed directly in front of the apparatus. Purification filters and a pressure relief valve are installed at the water supply point.
- Most Ariston models are equipped with a coaxial chimney - exhaust gases are removed through an opening in the wall.
- Additionally, the equipment is completed with a circulation pump.
- Control unit - regulation of hot water and heating medium temperature.
- Ariston models are non-volatile, therefore, the instruction prescribes the mandatory installation of the UPS.
