In order to warm a country house or cottage,perfect gas boiler. It is one of the popular teploagregatov that are used to heat the room. An important advantage of this equipment is that it runs on gas. Currently, it is the most economical fuel that is used for space heating. In addition, gas has a lower cost than other fuels. In order not to get lost in various heating equipment, it is necessary to study the device of a gas boiler and its components. Only then can you make the right choice of heat source. The device of a gas boiler of each type is approximately the same.
Items of equipment
The main elements will be as follows:
- Газовая горелка представляет собой конструкцию rectangular shape, inside which are located the nozzles. They serve to supply gas to the combustion chamber, as well as provide a uniform flame, thereby achieving uniform heating.
- As the heat exchanger acts as a box withradiators. Inside it there are pipes with a coolant, as a rule, it is water. When burning gas produces heat, which is transferred to the liquid. The device of a double-circuit gas boiler is characterized by the presence of two heat exchangers - primary and secondary.
- To provide pressure on the heating line using a circulation pump. This technical element may not be available in all types of gas boilers.
- If there is an intensive heating of the coolant, then it is necessary to take it away for some time. For this is the expansion tank.
- The important point is the removal of combustion products. They must be removed from the boilers using natural draft or an integrated fan.
- The automation system includes a gas boiler control unit, which is carried out using various sensors.
Gas valve
В настенных и напольных агрегатах предусмотрены these elements. The device valve gas boiler is designed to regulate the flow of gas into the burner. That is, the elements are opened and closed at the right moment.
Floor gas boiler
It is necessary to install this type of heat unit, subject to the availability of funds for its purchase, as well as sufficient space.
The room must meet all technical requirements. The device of the floor gas boiler is quite simple. The only difference from the other types is the presence of a double-circuit heat exchanger.
Advantages and disadvantages of floor boilers
Among the advantages of such structures are the following:
- it is not necessary to produce the filling of combustible material, as the boiler runs on gas;
- efficiency is quite high compared to fuel costs;
- careful heating of large areas.
The negative points include the following points:
- to install this type of gas boiler, it is necessary to collect the relevant documentation, which takes a lot of time;
- the inability to install butt to the enclosing structures;
- the need for arranging the premises with special ventilation for removal of combustion products.
Wall mounted gas unit
While remaining compact, such installations can perform the functions of an entire boiler room. The device of a wall gas copper differs in nothing from floor type, except overall dimensions.
Pros and cons of wall units
Among the advantages of this type of gas boiler are the following:
- compact size that allows you to install it with other appliances or furniture items;
- all necessary elements are included in the boiler package, installation of additional bulky equipment is not required;
- if there was no gas for a long time, the device can be easily reconfigured to use gas cylinders.
As with each unit, wall mounted boiler has its disadvantages:
- The device of gas heating boilers does not allow for heating a large area of the room.
- The presence of sensitivity to the chemical properties of the coolant. If you do not install an additional softener, the heat exchanger will quickly fail. And its replacement is quite expensive.
- If the device is a gas heating boilerprovides for a dual-circuit system, you must install an additional valve. In the open position, it serves to cool the coolant. Water supply starts 10 seconds after opening the tap.
Difference of wall equipment from outdoor
The device of the gas boiler floor typedifferent from wall products. This is expressed not only in cost, installation conditions, but also in technical parameters. They determine the type of boiler. In addition, floor models have a longer life. Such a characteristic is directly dependent on the material from which all structural elements are made. As a rule, boilers are made of a thick layer of cast iron, so that they do not corrode for a long time.
The design of the unit provides severaltypes of burners: atmospheric and ventilation. The first type is inexpensive and easy to operate, and does not cause much noise. The second type of burners is most often found in mounted boilers. They cost more, but they also have more power.
Protection system
The protection system is an important issue whenchoosing such equipment. When electricity is turned off, modern gas boilers stop and continue to work automatically when power is restored. In the event of a gas supply shutdown, only the burners close automatically. After that, the system is started up manually, as there is no automatic method.
The device of the gas boiler AOGV provides for the installation of frost protection, as well as energy-saving equipment. Thanks to the sensors, the temperature of the coolant is monitored.
When it is lowered to 5 ºС, the gas boiler is turned onto warm up. As you know, heating in the summer season is not required. Therefore, in order not to break the rotor, it is necessary to turn on the pump. For this purpose, a special function is provided in the boilers.
In modern devices setdiagnostic systems. They can independently analyze all elements and provide information about the general state of the system. Such models check up to 90% of all equipment. Thanks to this, specialists quickly replace or repair a specific device.
The cost of heating boilers
As mentioned earlier, the price of wall and floorboilers is different. So, the cost of wall-mounted models ranges from 28,000 to 150,000 rubles, and floor-standing - from 30,000 to 40,000 rubles. Do not forget that to install a floor-mounted unit, you must assemble a package of necessary documentation and equip a special room, which will result in additional financial costs.
The device and the operation of the gas boiler
You need to start with what is in the rooma thermometer that measures air temperature. If it falls, then the three-code valve switches to the “heating” position. Next, the circulation pump begins to work, and the water begins to move through the heating system.
Затем открывается газовый клапан, и горелка lights up. Heating of the coolant occurs due to the release of energy during the combustion of fuel. A thermostat and a pressure gauge are provided for measuring pressure and temperature. When the air temperature reaches the required parameters, the pump switches itself off. Over time, this heating process is repeated. With continuous operation of the pump, round-the-clock heating of the coolant occurs, which transfers its heat to heating devices.
Automation system
The built-in automation system plays a huge role in the functioning of gas boilers. It controls the operation of the unit in all modes and consists of the following elements:
- sensors that regulate the height of the flame in the burner, as well as its temperature;
- system of turning on and off the boiler in case of malfunction of the power network;
- gas pressure regulating sensors in the event of a gas supply failure;
- devices that protect against freezing, this is relevant for the cold season, when it is necessary to dismantle the boiler;
- equipment for turning on the circulation pump with long-term non-use of the system;
- system of self-diagnosis and detection of errors in the work of individual elements.
If you know the device of the gas boiler, you can easily choose the appropriate model, while saving money at the time of purchase and during operation.
Reviews
Opinions of users of wall and floor boilersdivided. After all, these designs have a number of differences. So, the wall unit can not warm a large area of the room than the floor equivalent. Therefore, people choose gas boilers, starting from this principle.
So, users of wall-mounted devices emita number of advantages. So, in their opinion, such units have small overall dimensions, which allows installation along with other elements. The negative side is the sensitivity to the coolant. If the water is of poor quality, the heat exchanger can quickly break. Its replacement is quite expensive.
Floor boilers surpass wall types in their technical characteristics and are used to heat a large area.
The only minus that many identifiedusers, is the installation process. For the installation of equipment it is necessary to allocate a separate room, as it is quite dimensional. You also need to collect certain documents, which takes a lot of time. Another important point is the removal of combustion products. In the room where the unit will be installed, it is necessary to equip the natural or mechanical ventilation.
Conclusion
Gas boiler is an important element.heating system. It is he who carries out the heating of the coolant, which later enters the pipes and radiators. Work on this type of fuel, like gas, is the best option for creating comfortable conditions in the room. So, we found out the gas boiler device. We hope that this information will help you choose the right device.
