Wall mounted gas boiler ariston bs ii 24 ff. Heating systems for country and country houses. Boilers, geysers, water heaters - Repair, service, operation. Recommendations for assembly and installation. Troubleshooting for models of this brand

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

A structural subdivision 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 central heating systems in apartment buildings.

In this review, we will look at some models of this brand, as well as their technical abilities. Instructions for use will be attached below.

Double-circuit wall heating systems

The variety of models from the Ariston trademark is quite large, but a review of Ariston gas boilers shows that the most popular is the line of double-circuit units. It assumes both hot water supply and space heating from one energy source. When installed in apartments or private houses with a total area of ​​up to 100 sq. m. most often purchased the following models, presented in the table below.

Instructions for double-circuit gas boilers Ariston are usually purchased along with all elements of the heating system. If you lost it, it does not matter, a little below is a brief instruction that will help you carry out daily management operations. It should be noted that, despite the lower gas consumption, the BS24FF model is a more advanced solution in terms of its operational capabilities. So instructions.

  1. For the first start, you must first make sure that there is air access to the room, ventilation is provided.
  2. Check the water pressure - it should be between 0.6-1.5 bar. Too low pressure requires feeding the circuit - for this you need to open the tap from the bottom of the boiler.
  3. Often a drop in pressure indicates that water is leaking from the system. This requires a wizard call.
  4. Switching on is simple - by pressing the on / off button.
  5. It is possible to select the "Winter" or "Summer" mode - respectively heating + DHW or only DHW.
  6. Using the regulation buttons, you can set the temperature of the coolant from 35 to 82°C and hot water - from 36 to 56°C.
  7. Turning off the boiler with the on / off button leads to the activation of the anti-freeze mode. If you want to turn off the boiler completely, you need to 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 indicates, 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 ​​\u200b\u200bthe kitchen, where products with an open combustion chamber are most often installed, should be much larger than in the previous case. Otherwise, it will cause a malfunction.

The efficiency also decreases somewhat. 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 designed 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 operation of the Uno 24FF model


The instruction of the gas boiler Ariston Uno considers in detail all issues related to the normal operation of the 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;
  • available for control automation of the work process, which provides for the "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 water heating in both circuits due to the built-in temperature sensor that controls the operation of the circulation pump;
  • precise settings of the parameters of the hydraulic and gas systems of the boiler;
  • reliable coaxial type chimney, 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 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 design solution for this type of technology. Its main features are listed below.

  1. Profitability, which is most evident when used in apartments or houses of a relatively small area.
  2. Unique hydraulic components of the unit, which ensure complete safety of its operation. In particular, the built-in gas supply regulator can be set to any power consumption mode.
  3. The affordability of the price creates the possibility of acquiring such a product for almost any potential consumer.
  4. The BS24FF boiler is fully adapted to domestic operating conditions, including reduced energy carrier pressure in the supply networks, possible voltage drops and low outdoor temperatures.
  5. 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 profile segment of the home heating equipment market. 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 constructive reliability of the equipment.

Troubleshooting for models of this brand

Despite all the efforts of manufacturers, periodic repairs to such intensively used products are inevitable. As with other systems of this class, possible problems are considered in the instruction manual. For double-circuit gas boilers Ariston, the most common malfunctions are as follows.

  1. Deterioration of gas supply. 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-burning device of the BS24FF boiler. This requires a thorough cleaning or flushing of the nozzles.
  2. 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. You can check this using the test value of the resistance of the coil winding, which is 5.8 kΩ for the primary winding and 19.2 kΩ for the secondary.
  3. Unsatisfactory gas flow through the burner, which causes its periodic shutdown. The cause may be a clogged gas supply valve or a broken membrane. Components and parts must be replaced at a service center.
  4. Increased noise during 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 make vibrating sounds. Depending on the severity of the breakdown, either the spring or the modulator itself will have to be changed.




An 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, and also strictly follow the rules for operating the equipment.
When these requirements are met, modern and aesthetic externally gas boilers Ariston BS24FF and Uno24FF will reliably perform their functions for many years.

For high-quality heating of the premises of private houses of medium size (250-300 m²), the Ariston BS24FF boiler, operating on natural gas, is perfect. This is a fairly reliable product of a well-known Italian brand, which is distinguished by an acceptable cost. Unfortunately, the instruction manual attached to it rather briefly describes the device and functions of the heating unit, so it is worth considering them in more detail.

General overview of the heat generator

The Ariston BS II 24 FF household water heater is a gas wall-mounted heat generator equipped with a closed combustion chamber and forced combustion air supply using a fan (suction). Due to this organization of fuel combustion, the efficiency of the unit is 93.8% in normal mode and 89.3% with minimal combustion. To remove flue gases from the house, a double-walled coaxial chimney is used.


Theoretically, the rated power of the boiler is 25.8 kW, which is enough to service the water heating system of a private cottage with an area of ​​up to 300 m², located in the central zone of the Russian Federation and properly insulated. With poor insulation or lack thereof, the power of the device is enough to heat no more than 250 m² of area.

The Ariston BS 24 gas boiler is a modern multifunctional unit that can operate in automatic mode and does not need constant supervision by the homeowner. In addition, it is equipped with a second heating circuit for preparing water for the needs of hot water supply.

As the instruction says, the device includes the following main components and elements:

  1. Controller. This is the electronic brain of the boiler, which controls its operation based on the readings of temperature, pressure and draft sensors, as well as signaling the current mode or malfunction.

  2. Burner device of modulating type. It can smoothly change the intensity of combustion at the command of the controller, thereby adjusting the power of the heat generator.
  3. primary heat exchanger. Serves for heating water in the heating network.
  4. secondary heat exchanger. Heats tap water for domestic hot water.
  5. Safety gas valve. Shuts off the gas supply regardless of the controller in case of emergency. These include a drop in fuel pressure in the line below 5 mbar, the disappearance of draft in the chimney and spontaneous extinction of the burner.
  6. Closed combustion chamber, insulated with basalt fiber.
  7. A fan that supplies air to the chamber and removes flue gases from there through a coaxial chimney.

In addition to the main elements, the Ariston BS 24 FF boiler is equipped with additional devices that turn it into a wall-mounted mini-boiler room.

This is a circulation pump equipped with an automatic air vent, and a membrane-type expansion tank with a capacity of 8 liters. The heat generator heats water for heating up to a temperature of 85°C, for hot water supply - up to 60°C. The operating pressure range in the heating system is from 0.6 to 1.5 bar, the maximum is 3 bar.


The maximum pressure for which the DHW circuit is designed is 7 bar. The wall-mounted boiler is able to provide water consumption for household needs up to 10 l / min when it is heated by 35 ° C.

Functions of the thermal unit

The wall-mounted gas boiler Ariston is equipped with many functions, which allows you to operate it with maximum comfort:

  • convenient front panel with operating temperature indicators and a pressure gauge showing the pressure in the heating network;
  • electric ignition, carried out in automatic mode;
  • protection against power surges in the network, freezing and the appearance of a layer of scale;
  • adaptability to Russian operating conditions at low gas pressure;
  • smooth change of burner operating modes (modulation), which allows burning fuel with maximum efficiency;
  • the possibility of switching to liquefied gas;
  • the unit is equipped with a container for collecting condensate flowing from the secondary heat exchanger when heating water for domestic hot water;
  • Possibility of connection of weather-compensated automation and room thermostat.

For the manufacture of elements of the heat generator, appropriate materials were used to ensure a long service life. The heating heat exchanger is made of copper and has an additional protective coating, the hot water treatment unit is made of stainless steel. The burner is also made of stainless steel and protected from clocking (frequent shutdowns).

Starting and running the heater

The instruction manual for the Ariston boiler says that to start it, just press the "ON" button, the controller of the device will do the rest. If after 10-12 seconds the start did not occur, then it is necessary to reset it with the "Reset" button and repeat the inclusion. A repeated unsuccessful start means that the automation does not allow switching on due to a malfunction. According to the instructions, you need to contact the service department, but some problems can be detected on your own:

  • low pressure in the heating network;
  • the heating system is filled incorrectly, there are air pockets in the boiler;
  • electrical network failures.

In accordance with the rules, the connection of a gas heating unit to the gas main and a test run must be carried out by specialists of an organization that has a permit for these types of work. Therefore, the first inclusion should not cause you problems.

After the burner is turned on, heating of the coolant begins up to the temperature set by the regulator on the front panel. If at this time the hot water tap is opened, the flow sensor in the boiler will work, and the three-way valve will switch the heat carrier flow to the second heat exchanger. The water in the DHW circuit will heat up to the temperature set by the second regulator.
