Gas boilers "Ariston": review and reviews

Boilers "Ariston" is an Italian product, but, unlike most "Europeans", it is adapted to our reality: the equipment will work at low gas pressure - 5 mbar, there is protection against voltage surges, there are two mechanical filters in the DHW and heating circuit. equipment is operable even at very low temperatures: up to -52 ° C. In general, almost all the dangers that can harm equipment are taken into account. Because, probably, there are practically no bad reviews about this technique. The only thing that can make you think is the lack of a service center nearby. For all other parameters, Ariston boilers are an excellent choice. And there are plenty to choose from.

Any equipment of this company regularly diagnoses the state of the system, in case of violation of certain parameters, stops the operation of the boiler, highlighting the corresponding state on the indicators or display (depending on the model). After a while, self-diagnosis is repeated, and if the parameters are set to normal, the boiler starts working again. A list of possible malfunctions and necessary actions is available in the user manual.

Ariston gas boilers have very good reviews

Traditional gas boilers

This group of heating equipment includes nine lines, each of which has from two to seven modifications. The group has both single-circuit and double-circuit units. Some lines are available in a wide range of capacities, some have only two or three modifications. All of them have automatic control, all can work with both coaxial and conventional chimneys. The control panel may differ, but in any version it is Russified, has a clear logic: to control the work, there is no need to read the instructions for a long time. Everything is clear even intuitively.

Each device in this group has the following elements, functions and capabilities:

Stainless steel burner, the operation of which is modulated depending on the required operating mode. Due to the modulating burner, fuel savings are achieved.
Self-diagnosis function. Some lines have a fault log.
A group of hydraulic devices made of high strength composite materials.
Expansion tank 8 liters.
The air from the heating system and the boiler is removed automatically.
Protection against freezing, blocking and scaling.
In double-circuit lines, the primary heat exchanger (for heating) is made of copper, and is covered with a protective layer for greater durability, the secondary (for hot water) is made of stainless steel.
In boilers with water preparation for hot water supply (double-circuit), it is possible to work only for heating water.
Built-in condensate collection tank.
Built-in temperature sensors (from 2 to 4 depending on the line).

The list is long, but there are also those functions that distinguish one line from another.

Double-circuit GENUS EVO

This line is equipped with open combustion chambers and has the third class of fuel combustion efficiency. Built-in automation regulates the operation of the equipment depending on the weather outside the window. It is possible to connect a solar collector (the boiler will coordinate its work taking into account the heat that will be generated by the collector), you can connect a touch control panel. The boiler is equipped with a pump and fan with smooth speed control.

Specifications GENUS EVO (click on the picture to enlarge)

There are only two modifications in the GENUS EVO line: 24CF and 30CF, which can produce a maximum of 25kW and 31kW of power, respectively (minimum 11kW and 13kW). Productivity for hot water supply at a water temperature of 35 ° C - 10.2 l / min and 11.3 l / min. Efficiency - 90-91% depending on the mode of operation.

Boilers GENUS

The units of this line are equipped with burners with a closed combustion chamber. They have the 4th class of energy efficiency, the "comfort" function - maintaining a constant temperature in the DHW circuit. The “Auto” control system itself adjusts the boiler operation mode depending on weather conditions and data from room sensors (3 pcs). There is also an electronic sensor that controls the water pressure. As well as in the previous line, it is possible to connect a solar collector and any control system. The unit has a system of automatic feeding of the system (a mechanical filter is installed on it). There are post-circulation and post-ventilation modes (post-circulation - the pump continues to operate after the burner is turned off to prevent overheating of the water, post-ventilation - the fan also continues to work after the burner is turned off to remove all combustion products and gas residues into the chimney).

Although this line is in the category of "traditional boilers", condensing technology is used in the work, due to which gas consumption is reduced by 35%, and the efficiency is at the level of 107%. There are three modifications in the GENUS line: 24FF, 30FF, 35FF. Maximum power 22kW, 28kW and 31kW, minimum 5.5kW, 6.7kW, 7kW. DHW capacity at a temperature difference of 35 ° C - 10.3 l / min, 12.9 l / min, 14.3 l / min.

Double-circuit wall-mounted boilers CLAS EV O

Functionally, this line is very similar to GENUS EVO. The only difference is that it has both modifications with an open chamber - 24CF, and with a closed 24FF and 30FF. For CF boilers, the efficiency is 91-92%, with a closed FF - 93%. For hot water, the performance in the 24CF modification is the same - 10.2 l / min, but for closed boilers it is slightly less - 9.9 l / min and 11.6 l / min, respectively.

Single circuit CLAS EVO SYSTEM

In these "Aristons" for heating there is a post-circulation mode, weather-dependent automation, a copper heat exchanger, the ability to connect any control (including touch), a solar collector. Models are available with both closed (15FF, 24FF, 28FF, 32FF) and open combustion chambers (15CF, 24CF, 28CF). The maximum power is from 16.5 kW to 32.5 kW, the minimum power is from 8.5 kW to 14 kW. Fuel combustion efficiency class:

2nd for modifications 15СF and 24CF
3rd for the rest.

Efficiency in the region of 90% for modifications CF (with an open combustion chamber) and 91-93% for FF (with a closed combustion chamber).

Ariston CLAS SYSTEM

Single-circuit heating gas boilers in wall-mounted version. They belong to the middle class of devices. There are modifications with open (CF) and closed (FF) burners. Powers 15,24,28 and 32kW (32 FF only). The boiler is single-circuit, but it is possible to connect an additional indirect heating boiler. There is a post-circulation mode.

The efficiency of boilers 15СF, 24CF, 28CF is in the region of 90-92%, 15FF, 24FF, 28FF, 32FF - 93.5-95%. The maximum heating power is 16.5-32.5 kW, the minimum is 7.3-14 kW.

Double-circuit boilers CLAS and BS II

These units are recommended by the manufacturer for heating apartments and preparing hot water in multi-storey buildings. There are only two powers in the CLAS line - 24 and 28 kW, but there is a 24CF modification. Belongs to the class "economy". No frills, but a sufficiently high level of comfort and high reliability of the equipment. The minimum productivity for hot water is 10.5 l / min modification 24CF; 10.7 l / min - 24FF; 12.1 l/min in a 28FF boiler.

The range of double-circuit boilers BS II has two powers of 15kW (only FF) and 24kW (both open and closed burners). Efficiency is 90-94.5% depending on the combustion mode, for the 15FF and 24CF modifications the fuel combustion efficiency class is 2nd, for the 24FF model it is 3rd. Boilers BS II have a slightly lower hot water capacity - 9.7 l / min.

Compact EGIS Plus

Another line of "economy" class, which has small dimensions (400*770*315mm) and weight (30kg). There is only one power - 24 kW, but there is an option with an open and closed combustion chamber. The fuel combustion efficiency class of 24CF is 2nd, efficiency is 92%, the 24FF modification has efficiency class 3 and is slightly higher than efficiency - 94%. Hot water with a temperature of 35 ° C produces a little less than 10 liters - 9.7 l / min.

Boiler CLAS B with built-in boiler

A very interesting model. There is a built-in stainless steel boiler of 40 liters. It takes up to 10 minutes to heat the entire volume of water. After the entire supply of water is used up, you continue to receive hot water, but it is already heated according to the principle of an instantaneous water heater. There are three modifications, two capacities: 24CF, 24FF, 30FF (24kW and 30kW, respectively).

As you can see, there are plenty to choose from. What remains unchanged is the quality of workmanship. Reviews There are very few negative things about traditional Ariston boilers. Almost everyone is either very happy or just happy. The water heats up quickly, the boiler is very quiet, it consumes little gas. There are almost no problems with the equipment. Management is easy and understandable. People for 3-5 years of operation had no problems. The only thing they pay attention to is the need to install water filters. Specialists from service centers also recommend putting a stabilizer on the power supply: although there is built-in protection against surges, it is more reliable with a stabilizer (in their opinion). As not the most pleasant moment, dependence on electricity is noted, but this applies to all boilers of recent years. To reduce this dependence and provide a house or apartment with heat during a power outage, you can install a UPS with batteries. With low consumption (for all Aristons of this group in the region of 120-150W / h), you can extend the operation of the system for several hours (without batteries) or up to several days (with batteries).

There are two or three negative assessments, which say that in cold weather the boiler does not warm up the premises. But this, rather, refers to the wrong choice of power. At another owner, the boiler is constantly clogged and has to be cleaned. The problem is easily solved if you put filters on water and gas.

Double-circuit boiler "premium" class GENUS PREMIUM

The power of this line is average: 24kW, 30kW and 35kW. There is a function of semi-automatic make-up of the heating circuit with water if necessary (a protective mechanical filter is installed on the make-up line). The burner is protected against frequent switching on. You can connect any automation, including those with a touch panel, connect a solar collector and control it. DHW capacity at a temperature difference of 35 ° C - 10.3 l / min - 14.3 l / min.

In general, Ariston boilers fail quite rarely. Even if this happens, service centers have most of the parts in stock. But for stable operation without failures, good traction, the correct form and within the required power supply are required. Additional filters at the inlet of water and gas will not interfere, although the boilers have built-in ones. Installation and start-up of the boiler to maintain 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. Here's how lucky anyone is. And in order to avoid controversial issues later, carefully read the documents and operating instructions, and only then act.
