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
domestic hot water device Ariston BS II 24 FF is a gas wall-mounted heat generator equipped with a closed combustion chamber and forced combustion air supply by means of 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 middle lane 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:
- 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.
- 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.
- primary heat exchanger. Serves for heating water in the heating network.
- secondary heat exchanger. Heats tap water for domestic hot water.
- Safety gas valve. Shuts off the gas supply independently of the controller when a emergencies. 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.
- Closed combustion chamber, insulated with basalt fiber.
- 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 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 indicators operating temperature 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 the faucet is opened at this time hot water, then the flow sensor in the boiler will work, and the three-way valve will switch the coolant flow to the second heat exchanger. The water in the DHW circuit will heat up to the temperature set by the second regulator.
