18.10.2019

The Italian trade mark Ariston, behind which a well-known world manufacturer is hidden household appliances Indesit Company has been designing and manufacturing gas heating boilers since the mid 70s of the last century.

The structural division of Indesit Company is the Ariston Thermo Group, whose gas boilers have gained popularity due to the intensive individual construction of residential buildings, as well as the unsatisfactory operation of centralized heating systems in apartment buildings.

In this review, we will take a look at some of the models of this brand, as well as their technical capabilities. Operating instructions will be attached below.

Double-circuit wall heating systems

Variety of models from brand Ariston is large enough, but a review of Ariston gas boilers shows that the most popular is the line of precisely double-circuit units. Here it is assumed both hot water supply and heating of premises from a single energy source. When installed in apartments or private houses with a total area of up to 100 sq. m. the following models are most often purchased, presented in the table below.

Instructions for Ariston double-circuit gas boilers are usually purchased along with all the elements heating system... If you have lost it, it doesn't matter, a little below is presented short instruction to guide you through your day-to-day control operations. It should be noted that, despite the lower gas consumption, the BS24FF model is a more advanced solution precisely in terms of its operational capabilities. So, the instruction.

For the first start-up, you must first make sure that there is air access to the room, ventilation is provided.
Check the water pressure - it should be between 0.6-1.5 bar. Too low pressure requires recharge of the circuit - for this you need to open the valve at the bottom of the boiler.
A frequently falling pressure indicates that there is a water leak from the system. This requires a call to the wizard.
Switching on is simple - by pressing the on / off button.
It is possible to select the "Winter" or "Summer" mode - respectively, heating + DHW or only DHW.
Using the regulation buttons, you can set the coolant temperature from 35 to 82 ° C and hot water- from 36 to 56 ° C.
Switching off the boiler with the on / off button activates the anti-freeze mode. If it is necessary to turn off the boiler completely, turn the external switch to the off position, unplug the boiler from the socket and close the gas cock.

The instruction for the gas boiler Ariston BS24FF notes the differences in the types of combustion chambers. She points out, in particular, that the presence of an open combustion chamber can lead to a lack of oxygen in the room where such a unit operates. Therefore, the useful area of the kitchen, where products with an open combustion chamber are most often installed, should be much larger than in the previous case. Otherwise, it will lead to a malfunction.

The coefficient also decreases slightly useful action... This is mainly due to the fact that boilers with a closed combustion chamber pump the air necessary for the operation of the fuel-burning device directly from the external atmosphere, heating it along the way, which helps to reduce gas consumption.

The instruction of wall-mounted gas boilers Ariston also notes their compactness and ease of installation. At the same time, the Uno 24FF model is intended for relatively small apartments or houses, while more productive options, for example, from the Clas series, are more suitable for installation in large mansions.

Features of the operation of the Uno 24FF model

Instructions gas boiler Ariston Uno considers in detail all issues related to the normal operation of equipment, has the following advantages:

advanced design of the heat exchanger with a developed heating area, which is the reason for the high efficiency of the boiler;
controllable automation of the work process, which provides for "summer" and "winter" modes of operation of the equipment;
blocking the operation of the fuel-burning device, which excludes the failure of the unit in case of interruptions in the supply of water and / or gas;
constant control of the temperature of heating water in both circuits thanks to the built-in temperature sensor that controls the operation circulation pump;
precise settings of the parameters of the hydraulic and gas system boiler;
reliable chimney of the coaxial type, which ensures timely and high-quality removal of combustion products.

The instruction manual for the Ariston gas boiler provides an overview of possible malfunctions, one of the most reliable in its class.

Features of the operation of the BS24FF model

What does the instruction for the Ariston gas heating boiler say? As you can see, this is a more modern constructive solution this type of equipment. Its main advantages are listed below.

Economy, which is most evident when used in apartments or houses of a relatively small area.
Unique hydraulic components of the unit, which ensure complete control of it. In particular, the built-in gas regulator can be set to any power consumption mode.
The affordability of the price creates the opportunity to purchase such a product for almost any potential consumer.
The BS24FF boiler is fully adapted to domestic operating conditions, including low pressure of the energy carrier in the supply networks, possible voltage drops and low outdoor temperatures.
The presence of high-precision diagnostic equipment minimizes the risks of premature failure of the boiler, while expanding its operational capabilities, for example, when installing thermostats in heated rooms.

As a result, reviews about the Ariston gas boiler are mostly positive. It is characterized by a steady demand in the specialized segment of the market for heating equipment for the home. The price range of the products in question is from 16,000 rubles. (for the Uno24FF model) up to 39,000 rubles. (for model BS24FF). The price difference is felt in the structural reliability of the equipment.

Troubleshooting for models of this brand

Despite all the efforts of the manufacturers, periodic repairs of such intensively used products are inevitable. Like other systems of this class, possible problems are considered by the operating manual. For Ariston double-circuit gas boilers, the most common faults are reduced to the following.

Deterioration of gas supply. It is more typical for the gas boiler Ariston Uno - the malfunction manifests itself in the clogging of the gas burner, which operates in less favorable conditions than the fuel combustion device of the BS24FF boiler. This requires thorough cleaning or flushing of the nozzles.
Lack of ignition of the burner when gas is supplied. Due to the presence of control automation, this malfunction is associated with a break in the gas valve windings. This can be checked using the test value of the resistance of the winding of the coils, which is 5.8 kΩ for the primary winding and 19.2 kΩ for the secondary.
Unsatisfactory gas flow through the burner, which causes periodic shutdowns. The cause may be a clogged gas supply valve or a broken diaphragm. Units and parts must be replaced at the service center.
Increased noise during the operation of the boiler (mainly found in products of the Uno24FF model). The reason is the breakage of the modulator spring, which as a result begins to emit vibrating sounds. Depending on the severity of the breakdown, you will have to change either the spring or the modulator itself.

The analysis of these breakdowns indicates that during the operation of the Ariston BS24F gas boiler, malfunctions are more rare. At the same time, in order to extend the service life of the equipment, it is also necessary to periodically check the chimney system, the quality of electrical connections, their grounding, the condition of the chimney pipes, the reliability of ventilation in the room where this equipment is installed, as well as strictly observe the rules of equipment operation.
If these requirements are met, modern and aesthetically pleasing gas boilers Ariston BS24FF and Uno24FF will reliably perform their functions for many years.

Gas boilers Ariston appeared on the Russian heating market among the first. Largely due to its worldwide famous brand, this Italian manufacturer of gas heating equipment quickly managed to "win" a domestic buyer and achieve high sales dynamics.

The Ariston gas boiler, the owners' reviews of which help to better decide on the purchase, we can often find on different sites and in online stores. Modern feature set and good design, not bad specifications and a large selection of models are a clear advantage when buying a device, even though the prices are somewhat overpriced.

But today we will consider not only the pros, but also the disadvantages of Ariston mounted boilers, having studied their structure and features of the models, using the operating instructions, photos, customer and professional reviews.
